The consistent presence of the human accessory deep peroneal nerve. (1/777)

Twenty-four human legs were dissected macroscopically to study the morphological details of the accessory deep peroneal nerve. This nerve arose from the superficial peroneal nerve and descended in the lateral compartment of the leg, deep to peroneus longus along the posterior border of peroneus brevis. Approaching the ankle joint, this nerve passed through the peroneal tunnels to wind around the lateral malleolus; it then crossed beneath the peroneus brevis tendon anteriorly to reach the dorsum of the foot. The accessory deep peroneal nerve was found in every case examined and constantly gave off muscular branches to peroneus brevis and sensory branches to the ankle region. In addition, this nerve occasionally had muscular branches to peroneus longus and extensor digitorum brevis, and sensory branches to the fibula and the foot. The anomalous muscles around the lateral malleolus were also innervated by this nerve. Neither cutaneous branches nor communicating branches with other nerves were found. The present study reveals that the accessory deep peroneal nerve is consistently present and possesses a proper motor and sensory distribution in the lateral region of the leg and ankle. It is not an anomalous nerve as has previously been suggested.  (+info)

Microdissection-based analysis of mature ovarian teratoma. (2/777)

The genotypic features of mature ovarian teratomas (MOTs) are controversial. Early studies detected a homozygous genotype in MOTs suggesting that these tumors are composed of germ cells that have undergone meiosis I. Other studies, however, revealed a heterozygous genotype in a substantial proportion of MOTs suggesting an origin either from premeiotic germ cells or from a somatic cell line. In view of the complex morphology of MOTs and to increase the sensitivity of teratoma genotyping, we applied tissue microdissection before genetic analysis of teratomatous tissue. This approach allowed selective analysis of different heterotopic tissue elements as well as the lymphoid tissues within MOTs the origin of which is unknown. After DNA extraction, the tissue samples were polymerase chain reaction amplified using a random panel of highly informative genetic markers for different chromosomes to evaluate heterozygosity versus homozygosity. In all seven cases that were analyzed, heterotopic tissues consistently revealed a homozygous genotype with several markers; in two cases, heterozygosity was detected with a single marker, indicating a meiotic recombination event. Lymphoid aggregates within MOTs were heterozygous and derived from host tissue rather than from teratomatous growth. However, well differentiated thymic tissue was consistently homozygous, suggesting lymphoid differentiation capability of MOTs. We conclude that potential pitfalls in genotyping of teratomas including meiotic recombination and host cell participation can be avoided by a microdissection-based approach in combination with a panel of genetic markers.  (+info)

The possibility of deep peroneal nerve neurotisation by the superficial peroneal nerve: an anatomical approach. (3/777)

Neurotisation involves transfer of nerves for the restoration of function following injury. A number of nerves have been used in different part of the peripheral nervous system. This study was undertaken to develop a practical and relatively safe surgical approach to the treatment of L4 root lesion's. We examined the effectiveness and safety of neurotisation of the deep peroneal nerve and its branches by the superficial peroneal nerve. Twelve legs of dissected cadavers provided for teaching purposes in the anatomy laboratory were used to display the common peroneal nerve and its branches. Each branch was measured using calipers and analysed to investigate the possibility of neurotisation of the deep peroneal nerve by the superficial peroneal nerve and its branches. It was found that of the measured branches, transposition was possible between those to peroneus longus and tibialis anterior on the basis of their diameter and length. In recent decades, advances in microsurgical reconstruction and understanding of the microanatomy have played major roles in improving the results of surgical treatment of nerve injuries. There is a need for further experimental studies on the feasibility of this surgical approach.  (+info)

Telomerase activity in ductal carcinoma in situ and invasive breast cancer. (4/777)

The increasing number of breast carcinoma in situ detected by screening procedures makes it imperative to develop improved markers to stratify the risk of invasive cancer. Telomerase is detectable in invasive cancer, but not in normal tissues. We have microdissected frozen tissue blocks containing both DCIS and invasive cancer to assay the telomerase activity of these two lesions. The 46 available cases of concurrent DCIS and invasive breast cancer resulted in 43 DCIS samples and 38 invasive cancer samples adequate for analysis. Seventy per cent of the DCIS and all invasive cancer samples tested had detectable telomerase activity. In addition, we analysed telomerase activity in ten cases of DCIS that were not associated with invasive cancer, and detected telomerase activity in seven (70%). Mixing experiments showed no evidence of telomerase inhibitors in telomerase negative samples. Furthermore, periductal inflammatory infiltrates were shown to be a potential confounding source of telomerase activity. Since DCIS lesions appear to be heterogeneous with respect to telomerase activity, and telomerase activation appears to precede the development of invasive cancer, telomerase activity may be a useful adjunct in stratifying the risk of developing invasive breast cancer in patients with DCIS.  (+info)

Quantification of nitric oxide synthase activity in microdissected segments of the rat kidney. (5/777)

This study was designed to quantify nitric oxide synthase (NOS) activity in microdissected glomeruli (Glm), pars convoluta, pars recta, cortical collecting duct, cortical thick ascending limb, outer medullary collecting duct, medullary thick ascending limb and thin limb, inner medullary collecting duct (IMCD) and thin limb, and vasa recta (VR). Total protein from microdissected segments was incubated with L-[3H]arginine and appropriate cofactors, and the L-arginine and converted L-citrulline were separated by reverse-phase HPLC and radiochemically quantitated. NOS activity was found to be greatest in IMCD (11.5 +/- 1.0 fmol citrulline. mm-1. h-1) and moderate in Glm (1.9 +/- 0.3 fmol. glomerulus-1. h-1) and VR (3.2 +/- 0.8 fmol. mm-1. h-1). All other renal structures studied exhibited significantly less NOS activity. The mRNA for NOS isoforms in the NOS activity-positive segments was then identified by RT-PCR. The IMCD contained mRNA for neuronal (nNOS), endothelial (eNOS), and inducible NOS (iNOS), but Glm and VR only expressed the mRNA for nNOS and eNOS. These experiments demonstrate that the greatest enzymatic activity for NO production in the kidney is in the IMCD, three- to sixfold less activity is present in the Glm and VR, and minimal NOS activity is found in other segments studied.  (+info)

Composite low grade B-cell lymphomas with two immunophenotypically distinct cell populations are true biclonal lymphomas. A molecular analysis using laser capture microdissection. (6/777)

Low grade B-cell lymphomas comprise several well defined, clinically and immunophenotypically distinct disease entities. Composite lymphomas showing phenotypic characteristics of more than one of these tumor subtypes in the same site are rare, and both common and separate clonal origins of the two tumor parts have been reported for cases studied by molecular methods. We describe the detailed immunohistochemical and molecular findings in three cases with features of composite low grade B-cell non-Hodgkin's lymphoma (B-NHL). All three neoplasms contained morphologically distinct but interwoven compartments of different cell types, which exhibited discordant expression of several markers, including CD5, CD10, CD43, and cyclin D1. According to their morphology and phenotypes, they were classified as mantle cell lymphoma and follicular lymphoma (Case 1), follicular lymphoma and small lymphocytic lymphoma (Case 2), and mantle cell lymphoma and chronic lymphocytic leukemia/small lymphocytic lymphoma (Case 3). PCR analysis of DNA obtained from whole tissue sections failed to reveal evidence for biclonality in any of the cases. We therefore isolated cell populations with different antigen expression patterns by laser capture microdissection and analyzed them by polymerase chain reaction amplification and sequencing of clonal immunoglobulin heavy chain gene rearrangements and oncogene rearrangements. Sequence analysis revealed unrelated clonal rearrangements in each of the two tumor parts in all three cases, suggesting distinct clonal origins. In addition, Case 1 showed a bcl-2 rearrangement present only in the follicular lymphoma part. Our findings suggest that low grade B-NHL with two distinct morphological and immunophenotypic patterns in the same anatomical site are frequently biclonal. This is in keeping with current classification schemes, which recognize subtypes of low grade B-NHL as separate disease entities. Furthermore, our analysis demonstrates the power of laser capture microdissection in revealing molecular microheterogeneity in complex neoplasms.  (+info)

Testicular sperm extraction: microdissection improves sperm yield with minimal tissue excision. (7/777)

Testicular sperm extraction (TESE) is often an effective method for sperm retrieval from men with non-obstructive azoospermia. However, TESE has been a blind procedure that does not identify the focal sperm-producing areas of the testicle until after tissue has been excised from the patient. Experience with a new technique of microdissection of testicular tubules is presented here that identifies sperm-containing regions before their removal. Identification of spermatogenically active regions of the testicle is possible by direct examination of the individual seminiferous tubules. The underlying concept for this technique is simple: seminiferous tubules containing many developing germ cells, rather than Sertoli cells alone, are likely to be larger and more opaque than tubules without sperm production. In a sequential series of TESE cases for men with non-obstructive azoospermia, the ability to find spermatozoa increased from 45% (10/22) to 63% (17/27) after introduction of the microdissection technique. Microdissected samples yielded an average of 160,000 spermatozoa per sample in only 9.4 mg of tissue, whereas only 64,000 spermatozoa were found in standard biopsy samples that averaged 720 mg in weight (P < 0.05 for all comparisons). For men where microdissection was attempted, successful identification of enlarged tubules was possible in 56% (15/27) of cases. However, spermatozoa were retrieved with microdissection TESE for six men in whom sperm retrieval was unsuccessful with standard TESE approaches (35% of all men with spermatozoa retrieved). These findings suggest that microdissection TESE can improve sperm retrieval for men with non-obstructive azoospermia over that achieved with previously described biopsy techniques.  (+info)

Endoscopic harvesting of the greater saphenous vein for aortocoronary bypass grafting. (8/777)

We conducted an observational study to evaluate the effectiveness of an endoscopic technique for harvesting the greater saphenous vein for aortocoronary bypass grafting. We hypothesized that the endoscopic technique would minimize the risk of postoperative wound complications. From May 1997 to July 1998, we used an endoscopic technique to harvest the greater saphenous vein in 50 patients who underwent aortocoronary artery bypass grafting. Twenty-five of the patients had an increased risk for wound complications due to preexisting diabetes, obesity, peripheral vascular disease, or lymphedema. The average duration of the procedure was 39 minutes (range, 11 to 70 minutes). The average length of the harvested vein was 58 cm (range, 25 to 85 cm). We made an average of 2.5 incisions per patient (range, 1 to 5 incisions), and the average incision length was 7 cm (range, 3 to 10 cm). Two patients (4%) required conversion to an open technique using 5 small incisions. Postoperative complications included 1 wound infection (2%) and 1 small hematoma (2%). Two patients (4%) had minor erythema at the incision site, and 5 patients (10%) had postoperative lymphedema. The most common problem, ecchymosis, was seen in 6 patients (12%). None required repeat hospitalization or reoperation for wound complications. In our study, the endoscopic approach yielded superior cosmetic results, and reduced wound complications and discomfort, compared with traditional methods of vein harvesting. After gaining expertise with this minimally invasive method of vein harvesting, a surgeon can safely remove the saphenous vein in 20 to 30 minutes.  (+info)

22A A COMPARISON OF ILEAL DIGESTIBILITY USING CANNULATION AND DISSECTION TECHNIQUES R.J. VAN BARNEVELD*, E.S. BATTERHAM*, and B.W. NORTON** Ileal digestibility is widely used in diet formulation for pigs, and is normally determined using T-piece or re-entrant cannulas. Ileal cannulation allows multiple sampling from a single animal and causes little disturbance to the digestive tract. Leakage around the cannula is prevalent, however, and the studies are consequently highly labour intensive. An alternative is the intact ileal dissection technique involving removal of the terminal ileum and the collection of its contents. During an investigation into the ileal digestibility of lysine in heat-treated field peas, results were compared from ileal cannulation and dissection techniques respectively (Table 1). Four male pigs (40-45 kg) fitted with T-piece cannulas were utilised in the cannulation study. All pigs were fed 4 diets (4x4 Latin square) for a period of 7 days prior to a continuous 2 day ...
Introduction: Endoscopic submucosal dissection has been widely accepted as a standard treatment for early gastric cancers. However, endoscopic submucosal dissection for an early gastric remnant cancer post-proximal gastrectomy with jejunal interposition is not yet widespread. Case Series: A large, flat, elevated lesion was detected in an 83-year-old male (Case 1), whereas two separate flat, elevated lesions were detected in a 75-year-old male (Case 2). Successful curative en bloc resection of these lesions by endoscopic submucosal dissection using the insulation-tipped diathermic knife-2 revealed well-differentiated adenocarcinoma confined to the mucosa. No postoperative bleeding nor perforation was observed in the present cases. Conclusion: These cases underscore the importance of periodic upper gastrointestinal endoscopy follow-up and the value of endoscopic submucosal dissection using the insulation-tipped diathermic knife-2 for treating early gastric remnant cancers post-proximal gastrectomy in the

BACKGROUND: There have been no studies of the structure and safe surgical entry zones of the brainstem based on fiber dissection studies combined with 3-dimensional (3-D) photography.. OBJECTIVE: To examine the 3-D internal architecture and relationships of the proposed safe entry zones into the midbrain, pons, and medulla.. METHODS: Fifteen formalin and alcohol-fixed human brainstems were dissected by using fiber dissection techniques, ×6 to ×40 magnification, and 3-D photography to define the anatomy and the safe entry zones. The entry zones evaluated were the perioculomotor, lateral mesencephalic sulcus, and supra- and infracollicular areas in the midbrain; the peritrigeminal zone, supra- and infrafacial approaches, acoustic area, and median sulcus above the facial colliculus in the pons; and the anterolateral, postolivary, and dorsal medullary sulci in the medulla.. RESULTS: The safest approach for lesions located below the surface is usually the shortest and most direct route. Previous ...
bjective: Esophageal tumors arising in the muscularis propria are difficult to be resected endoscopically using standard electro surgical techniques, even the endoscopic submucosal dissection (ESD) technique appeared recently. Our purpose is to investigate the efficacy of endoscopic ultrasound (EUS)-assisted tunnel-type ESD for resection of these tumors. Methods: A total of 17 patients were included in this study. A standard endoscope was used. The submucosal tunnel was created with the triangle knife according to the standard ESD technique, about 5 cm proximal to the lesion. EUS was performed within the tunnel to detect the tumor, and then the tumor was separated both from the submucosal and the muscle layers. After the tumor was removed, several clips were used to close the mucosal defect. EUS was performed to evaluate the healing quality 1 week after the procedure. Result: In all the cases, the tumors were completely resected. Mean tumor size was 24.2 mm (12-50 mm) in diameter. The histo ...
Colonoscopy plays an increasingly important role in the diagnosis and treatment of colorectal pathologies. The recent progress in endoscopic technologies and interest in colorectal cancer screening have enabled the diagnosis of a larger number of early colorectal neoplasms, including benign polyps and early cancers. Colonoscopic polypectomy remains the cornerstone of therapy for the majority of colorectal polyps and helps prevent colorectal cancer. However, if colorectal neoplasms are too large or cannot be removed en bloc endoscopically, operative procedures are required to reduce risks of incomplete removal and local recurrence. Laparoscopic resection represents a minimally invasive alternative for treating colorectal neoplasms that are not amenable to en bloc endoscopic resection. However, laparoscopic surgery has to be done under general anesthesia, is associated with operative morbidity, and is expensive.. Endoscopic submucosal dissection (ESD) is a revolutionary endoscopic procedure that ...

The Glissonean pedicle transection method has been reported to shorten operation time, reduce intraoperative blood loss, and minimize surgical risks in HCC patients undergoing hepatectomy 22. The Glissonean approach may therefore be more beneficial for HCC patients undergoing curative resection than other hilar vascular control methods such as the Pringle maneuver. However, in a large series, only 17.1% of patients underwent major hepatectomy involving two or more segments, with most patients (80.3%) undergoing segmentectomy or subsegmentectomy18. Our patient cohort differs in the extent of liver resection as well as including only patients with large (, 5 cm) nodular HCCs. 56% Of the 25 patients in our Glissonean group, 14 (56%) underwent removal of more than 2.5 segments (right trisegmetectomy).. To our best knowledge, our study is the first to compare the surgical effectiveness and safety of Glissonean transection with the Pringle maneuver in patients with large HCC undergoing radical ...
Results Indications were suspected early rectal (14/36), sigmoid (1/36) or gastric cancer (4/36), gastric NETs (2/36), scarred colonic adenomas (7 rectal, 1 transverse colon), or adenomas abutting dentate line (5/36). Mean diameter of lesion was 3.5 cm (1-7 cm). Median total procedure time fell between study periods (110 v 90mins, p=NS). R0 resection rates significantly improved after 20 cases from 45% to 85.7% (p=0.016) and use of KAR techniques significantly reduced (65% v 21.4%, p=0.012). R0 resection rates were significantly reduced when KAR was used (43% v 78%, p=0.042). When procedures using KAR were excluded, time/cm2 fell from 43.8 to 30 mins/cm2, p=NS). Perforation was seen in one patient in the first 20 cases (sealed with clips, surgery not required). No significant post procedural bleeding was seen. 30/34 patients have completed 3 month follow up; recurrence was 7.1% after R1% and 0% after R0 en-bloc resection. 1 patient underwent surgery for sm3 disease. ...

Endoscopic submucosal dissection (ESD) is capable of en-bloc resection of lesions regardless of their size. This has not only enabled accurate histopathological examination, but also preservation of organs, already making it a standard treatment modality for early gastric cancer, particularly in Japan. ESD has also been listed as an insured treatment in Japan for superficial oesophageal cancer, as well as gastric cancer. However, ESD for colorectal cancer has not yet been established as a standard treatment modality, due to the difficulty of the techniques and because the pathological characteristics of colorectal cancer are radically different from those of oesophageal and gastric cancers. In view of this, the Working Group for Standardisation of Colorectal ESD was started as a subordinate organisation of the Japanese Gastrointestinal Endoscopy Promotion Liaison Committee in April 2006. The committee is presently clarifying the colorectal tumours for which ESD can be indicated, improving the ...

Our aim was to demonstrate respiratory disturbances using polysomnography (PSG) during propofol sedation for gastric endoscopic submucosal dissection. Among the ten patients, 207 respiratory disturbances were identified by PSG. Apnea hypopnea index (AHI), defined as the number of apnea and hypopnea per hour, detected by PSG was signifi-cantly greater than that detected by pulse oximeter. Obstructive AHI was significantly greater than central AHI. The 25 instances of respiratory disturbances with hypoxemia were detected on an average of 107.4 s before they were detected by pulse oximetry. PSG would be useful for monitoring respiratory conditions with better detectability of AHI ...

Irving S. Wright describes patients with similar symptoms and signs as those with costoclavicular syndrome. However, Wrights patients experience symptoms with hyperabduction of the arms (elevation of the arms above the head). Interestingly, Wright could not reproduce symptoms or pulse obliteration in his patients by using the maneuvers used by Falconer.. Wright went on to test 150 asymptomatic volunteers by performing hyperabduction of their arms while monitoring their pulse. In nearly 90% of volunteers, Wright induced obliteration of the radial pulse, despite the volunteers having no symptoms. In only two of the 150 patients could Wright induce tingling, presumed to represent nerve compression. Interestingly, neither of these patients had a loss of pulse in the same arm position. Wright concluded that clinical obliteration of the pulse was not correlated with compression of the brachial plexus.. Wright also performed anatomic dissections to further understand the underlying mechanism of ...

A hinged dissection of a set of polygons S is a collection of polygonal pieces hinged together at vertices that can be folded into any member of S. We present a hinged dissection of all edge-to-edge gluings of n congruent copies of a polygon P that join corresponding edges of P. This construction uses k n pieces, where k is the number of vertices of P. When P is a regular polygon, we show how to reduce the number of pieces to ⌈k / 2⌉ (n − 1). In particular, we consider polyominoes (made up of unit squares), polyiamonds (made up of equilateral triangles), and polyhexes (made up of regular hexagons). We also give a hinged dissection of all polyabolos (made up of right isosceles triangles), which do not fall under the general result mentioned above. Finally, we show that if P can be hinged into Q, then any edge-to-edge gluing of n congruent copies of P can be hinged into any edge-to-edge gluing of n congruent copies of Q ...

Background: Endscopic mucosal resection (EMR) has been accepted as a treatment of early gastric cancer (EGC). The number of EMR procedures for EGC has been increasing because a patients quality of life after EMR is superior to that after surgical gastrectomy. The recently developed EMR procedure, endoscopic submucosal dissection (ESD), makes en-bloc resection possible for mucosal cancer regardless of the size of cancer. In addition, this procedure enable to resect in one piece, therefore accurate pathology can be diagnosed. In Japan, although the number of patients with EGC treated by ESD has increased, the appropriate strategy for treating those with non-curative resection has not been established. Laparoscopic gastrectomy (LG) with regional lymph node dissection has been used in the treatment of EGC with low mortality and morbidity and improvement in patients quality of life. We performed ESD and LG, by these combinations for EGC. However, ESD is deeper and wide dissection on the gastric ...
Background and Aim: Endoscopic submucosal dissection (ESD) enables complete, collective removal of gastrointestinal (GI) malignant tumors, but requires a long operation time. Air insufflated during ESD is distributed throughout the entire GI tract, and thus causes an enlarged feeling of the abdomen. We aimed to reduce the incidence of an enlarged feeling of the abdomen by wedging a balloon in the bulbus duodeni to reduce air flow into the lower parts of the GI tract.. Methods: Sixteen patients who were approved by the institutional ethics committee and provided consent to participate in this single-center, prospective study were divided into two groups using a sealed-envelope randomization method: ESD with a balloon wedged in the bulbus duodeni (the balloon [+] group) or conventional ESD with no balloon (the balloon [−] group). Total air volume in the entire GI tract and its change before and after ESD were measured objectively by 3-D computed tomography.. Results: In the balloon (+) group, ...

The superficial external pudendal artery (superficial external pudic artery) is one of the three pudendal arteries. It arises from the medial side of the femoral artery, close to the superficial epigastric artery and superficial iliac circumflex artery. After piercing the femoral sheath and fascia cribrosa, it courses medialward, across the spermatic cord (or round ligament in the female), to be distributed to the integument on the lower part of the abdomen, the penis and scrotum in the male, and the labium majus in the female, anastomosing with branches of the internal pudendal artery.

With the patient initially lying in the left lateral position, a full colonoscopy was first performed to confirm and locate the site of pathology. Patients were then re-positioned such that the lesion was at an anti-gravitational position in the endoscopic view at 6 oclock. This could be easily achieved by seeing the injected water pooling opposite to the lesion. In this position, the gravitational force aided in retracting the lesion away from the submucosal plane during dissection. We then injected 1:100 000 adrenaline saline at 1 cm distal to the lesion, aiming at the submucosal layer. This could be ascertained by seeing the formation of a dwell. With the injecting needle still in situ, the solution was then changed to the mixture of adrenaline saline and sodium hyaluronate to provide a precipitous elevation of sufficient height. After elevating the lesion, a mucosal incision was made proximal to the lesion. The mucosal incision was started at the proximal two thirds of the lesion. After ...
Endoscopic mucosal resection (EMR) is widely accepted as a minimally invasive treatment for GI neoplasms.However, one disadvantage of EMR is that lesions larger than 2 cm in diameter must be removed in pieces, which may result in a high recurrence rate of residual tumor tissue. In addition, in most patients, pathological assessment cannot be conducted after the procedure. ESD can overcome the disadvantages of EMR. However, it is difficult to perform ESD for GI neoplasms because of the high rate of complications ...
Knowledge of anatomical location of Superficial External Pudendal Artery (SEPA), its origin and course is very important while exploring SFJ and ligating its various branches.
Firstly, a small incision was made on the peripheral mucosa near the diverticula to clearly identify the submucosa, followed by submucosal injection of 0.4% hyaluronate sodium solution (MucoUp; Johnson & Johnson K.K., Tokyo, Japan) with a needle knife (KD-441Q; Olympus, Tokyo, Japan). The mucosa nearest to diverticula was dissected using the needle knife from the peripheral mucosa toward the side of diverticula, resulting in safe and complete marginal cutting of the mucosa near the diverticula (Fig. 2), and followed by standard colorectal ESD. The entire dissected surface, including the diverticula, was sutured with hemoclips to prevent late complications. Histological examination revealed a curative resection of a carcinoma with adenoma. The patient was hospitalized for 1 week without associated complications and showed excellent postoperative outcomes.. ...

Connections between the insular cortex and the amygdaloid complex have been demonstrated using various techniques. Although functionally well connected, the precise anatomical substrate through which the amygdaloid complex and the insula are wired remains unknown. In 1960, Klingler briefly described the fasciculus amygdaloinsularis, a white matter tract connecting the posterior insula with the amygdala. The existence of such a fasciculus seems likely but has not been firmly established, and the reported literature does not include a thorough description and documentation of its anatomy. In this fiber dissection study the authors sought to elucidate the pathway connecting the insular cortex and the mesial temporal lobe. ...
Occurrence of metastatic cancer to the stomach is rare, particularly in patients with prostate cancer. Gastric metastasis generally presents as a solitary and submucosal lesion with a central depression. We describe a case of gastric metastasis arising from prostate cancer, which is almost indistinguishable from the undifferentiated-type gastric cancer. A definitive diagnosis was not made until endoscopic resection. On performing both conventional and magnifying endoscopies, the lesion appeared to be slightly depressed and discolored area and it could not be distinguished from undifferentiated early gastric cancer. Biopsy from the lesion was negative for immunohistochemical staining of prostate-specific antigen, a sensitive and specific marker for prostate cancer. Thus, false initial diagnosis of an early primary gastric cancer was made and endoscopic submucosal dissection was performed. Pathological findings from the resected specimen aroused suspicion of a metastatic lesion. Consequently,
The ultrasonic dissector does not possess hemostatic properties, but serves only to remove or divide parenchyma, exposing vascular structures and bile ducts. These structures can be then controlled with conventional technique (ligation, clipping, coagulation) or by the use of the harmonic scalpel. The ultrasonic vibration (range about 100 ,i) of the hand piece hollow titanium tip selectively destroys liver parenchyma cells because of their high water content. It preserves the vascular and bile duct structures due to their higher content of elastin and collagen. The tip of the hand piece is constantly irrigated. A suction line parallel to the hollow tip aspirates the irrigation fluid, blood, and small tissue fragments. The ultrasonic dissector allows a decrease in blood loss and provides extensive exposure and dissection of large anatomical structures like portal and hepatic venous branches [22, 23]. Preservation of these structures is necessary when the resected portion of the liver will be used ...
Of two PCS (n = 2), one migrated and one became embedded leading to difficult stent removal. Endoscopic clips have been used on gastric tumors, post‐sphincterotomies, arterio-venous malformations and diverticular bleeds. The precursor of colon cancer is called a polyp. As such, we do not routinely clip cold EMR defects but would consider doing so if there is pulsatile bleeding or ongoing oozing or a specific concern in a particular patient. Carr-Locke, Saltzman, and Soetikno discuss and demonstrate why they feel the Instinct is the best clip on the market! The arms are elongate linear cantilevered beams extending beyond the base and are biased to a first or closed position generally within the plane. Endoscopic removal of sessile and flat colonic lesions larger than 2 cm has become a standard procedure in most health care systems.2, 3. Standard polypectomy, endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are established techniques for the resection of superficial ...
Twenty tumors in 20 patients (13 males:7 females) with a mean age of 74.4 ± 7.5 were included. Mean tumor size was 27.6 ± 6.4 mm. Nearby vulnerable structure(s) were identified as the ureter in 5/20 cases, the PUJ in 8/20 cases and both the PUJ and the ureter in the remaining 7/20 cases (35%) cases. Mean minimal distance between the tumor and the vulnerable organ(s) was 4.8 ± 2.6 mm (range 0-10). A mean of 1.7 ± 0.6 spinal needles were used per intervention with a mean time to complete hydrodissection of 18.6 ± 13.4 min. Primary and secondary technical efficacy rates were 90% and 95%, respectively. Mean follow-up was 23.1 ± 9.2 months. There were no immediate or delayed complications, in particular no urothelial strictures. Two tumor recurrences occurred during follow-up, with a time to disease progression of 13 and 31 months, respectively ...

For the early IAL rectal cancer group (i.e., node negative patients who underwent polypectomy or endoscopic submucosal dissection before surgery due to incorrect T staging of the primary tumor), NL showed a statistical value in predicting DFS (p=0.016) and OS (p=0.014) (Table 3, Fig. 2). Therefore, in patients with three or less total lymph node, there was a difference in the DFS and OS, and close observation is warranted.. Johnson et al. [13] reported that increasing the negative lymph node count is independently associated with improved long-term survival in stage IIIB and IIIC colon cancer but not stage IIIA. They also divided patients into subgroups of those with ≤ 3, 4-7, 8-12, or ≥ 13 negative lymph nodes. Cumulative 5-year cancer mortality was 27% in stage IIIB patients with ≥ 13 negative nodes identified versus 45% in those with three or fewer negative lymph nodes evaluated (p , 0.001). In patients with stage IIIC cancer, those with ≥ 13 negative nodes had a 5-year mortality of ...

Endoscopic submucosal dissection is found to be a safe and effective treatment for patients with superficial pharyngeal cancer, according to a recent study.
education. To reduce the anxiety of the medical students by mentally preparing them before going to the dissection room. The questionnaires were distributed among 68 medical students. The pre-dissection questionnaire comprised questions related to demographic data and the first encounter with a cadaver. The students were randomly divided into experimental and control groups. The experimental group was prepared psychologically prior to dissection, but the control group entered the dissection room without any preparation. After the first dissection class, all students were surveyed by the second questionnaire which surveyed physical and cognitive symptoms of anxiety, resulting from exposure to the dissection room at the first visit and six weeks later.

Objective. We conducted this study to develop a sonographically guided approach to the spinal nerve of the lumbar spine and to assess its feasibility and accuracy by means of computed tomography (CT). Methods. Fifty sonographically guided approaches at 5 levels (L1-S1) were performed on 5 embalmed cadavers, which were positioned prone. The spinal nerves of the lumbar spine
Lung. Surgeons who altered the treatment of lung cancer by performing lobectomy, pneumonectomy, or segmental resection of the lung received considerable recognition. Hugh Davies performed the first lobectomy in 1912 using anatomic dissection ( 7, 8). In reporting the results of Davies operation, Naef wrote, If his patient had not died 28 days after the operation, he would have preceded Evarts Grahams first lung resection by 21 years ( 8). Although Davies also received acclaim for being … the earliest advocate of interdisciplinary teamwork in thoracic medicine ( 8), his publication provides no information related to lung cancer other than a technical description of how he performed the operation. A report by Harold Brunn of a single cancer patient who had a one-stage lobectomy provides information only about an operative technique he used ( 9).. Although Rudolph Nissen was credited with performing the first total pneumonectomy in 1931 ( 10), he was recognized for an operation that ...

IIDavid Chorn was previously Anatomy Teaching Prosector in the School of Biomedical Sciences, Queens Medical Centre, Nottingham, UK, and is currently Senior Tutor in Anatomy in the Faculty of Health Sciences at Wits. Correspondence. The dissection of human cadavers is a complex topic that can be comprehended only if a number of factors are taken into account, as illustrated by the example of Herophilus of Chalcedon, who was the first dissector in the Western medical tradition. The social, cultural, political and intellectual climate of Hellenistic Alexandria in the third century BC provided Herophilus with opportunities to dissect - and possibly vivisect - human bodies. He was thus able to make an unprecedented number of anatomical discoveries and accompanying accurate descriptions. Subsequent changes in Alexandrian society and its intellectual climate saw the rapid demise of the practice of dissection - its resurgence occurring only some 15 centuries later.. Probably no issue in medicine has ...

Objective: The purpose of this study was to evaluate whether ultrasound allows precise assessment of a focal defect at the lateral patellar retinaculum (LPR) and to determine its anatomical significance. Materials and methods: This work was initially undertaken in four cadaveric specimens and followed by high-resolution ultrasound study in 48 healthy adult volunteers (96 knees) by two musculoskeletal radiologists. Dimension and location of the LPR defect and its relations to adjacent anatomical structures were analyzed. Results: A focal defect of the LPR through which vessels penetrated was constantly identified by ultrasound in our population. The mean transverse diameter of the defect was 2.4 mm (range, 1-6 mm). The defect was located a mean of 23.7 mm (range, 18-30 mm) proximal to the lateral tibial plateau and 6.6 mm (range, 4-9 mm) lateral to the patellar tendon. Anatomical dissection demonstrated that the LPR defect is related to perforating vessels that originate from the peripatellar ...
Scientists in Edinburgh will perform the first public anatomy lectures using human bodies since the 1800s, when serial killers Burke and Hare profited from selling corpses to a medical school.
A method for removing a vessel from a patients body comprises the steps of identifying the vessel to be removing and providing an incision in the patients body near the identified vessel. An optical dissector is inserted through the incision and tissue is optically dissected away from the surface of the vessel with the optical dissector. The optical dissector is then withdrawn from the body through the incision. An optical retractor is inserted into the body through the incision and is used to retract the dissected tissue away from the surface of the vessel thereby providing space between the dissected vessel and the retracted tissue. The vessel and its side branches are then dissected, ligated and transected and the vessel is then removed from the body through the incision.

Several cell adhesion molecules involved in neuron-neuron and neuron- glia interactions have been identified in our laboratory and have been shown to undergo cell surface modulation. In the case of the neural cell adhesion molecule (N-CAM), it has been found that during development the molecule is converted from a microheterogeneous embryonic (E) form containing 30 gm of sialic acid/100 gm of polypeptide to several distinct adult (A) forms containing one third as much of this sugar. In vitro analyses indicate that this change is accompanied by a 4-fold increase in the rate of N-CAM homophilic binding. In the present study of the mouse and the chick, alterations of N-CAMs occurring as a result of E----A conversion, prevalence modulation, and changes in antigenic state during the development of different neural regions were analyzed by the use of highly specific polyclonal and monoclonal antibodies combined with anatomical dissection and several new quantitative assays. We made the following ...
Long rectangles (80mm x700mm) were cut from artificial fur fabric. The two long edges were sewn together and overlocked, with the fur on the inside.
