Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.

A blind comparison of the effectiveness of endoscopic ultrasonography and endoscopy in staging early gastric cancer. (1/935)

BACKGROUND/AIMS: Endoscopic ultrasonography is expected to be useful for invasion depth staging of early gastric cancer. A prospective blind study of the staging characteristics of endoscopy and endoscopic ultrasonography for early gastric cancer was performed. METHODS: Findings of endoscopy and endoscopic ultrasonography using a 20 MHz thin ultrasound probe were independently reviewed and the results of 52 early gastric cancer lesions analysed. RESULTS: The overall accuracy rates in invasion depth staging of early gastric cancer were 63% for endoscopy and 71% for endoscopic ultrasonography. No statistically significant differences were observed in overall accuracy. Endoscopic ultrasonography tended to overstage, and lesions that were classified as mucosal cancer by endoscopic ultrasonography were very likely (95%) to be limited to the mucosa on histological examination. All 16 lesions staged as mucosal cancer independently but coincidentally by both methods were histologically limited to the mucosa. CONCLUSIONS: Endoscopic ultrasonography is expected to compensate for the understaging of lesions with submucosal invasion that are endoscopically staged as mucosal cancer.  (+info)

Double gallbladder originating from left hepatic duct: a case report and review of literature. (2/935)

BACKGROUND: Double gallbladder is a rare anomaly of the biliary tract. Double gallbladder arising from the left hepatic duct was previously reported only once in the literature. CASE REPORT: A case of symptomatic cholelithiasis in a double gallbladder, diagnosed on preoperative ultrasound, computed tomography (CT) and endoscopic retrograde cholangiopancreatogram (ERCP) is reported. At laparoscopic cholangiography via the accessory gallbladder no accessory cystic duct was visualized. After conversion to open cholecystectomy, the duplicated gallbladder was found to arise directly from the left hepatic duct; it was resected and the duct repaired. CONCLUSIONS: We emphasize that a careful intraoperative cholangiographic evaluation of the accessory gallbladder is mandatory in order to prevent inadvertent injury to bile ducts, since a large variety of ductal abnormality may exist.  (+info)

Transvaginal ultrasonography in the assessment of organic diseases of female urethra. (3/935)

The current investigation aimed to check the effectiveness of transvaginal ultrasonography in the diagnosis of organic urethral diseases, comparing its results with those of conventional examinations (physical examination, voiding cystourethrography, pelvic ultrasonography, cystourethroscopy). Transvaginal ultrasonography was performed in 560 female patients with recurrent cystitis, dysuria, or palpable masses and diagnosed the following urethral diseases: 25 diverticula, seven stenoses, three carcinomas, two leiomyomas of periurethral tissue, and one incomplete duplex urethra. In our study transvaginal ultrasonography proved to be the most reliable diagnostic tool among imaging methods used.  (+info)

Artificial neural network models for the preoperative discrimination between malignant and benign adnexal masses. (4/935)

OBJECTIVE: The aim of this study was to generate and evaluate artificial neural network (ANN) models from simple clinical and ultrasound-derived criteria to predict whether or not an adnexal mass will have histological evidence of malignancy. DESIGN: The data were collected prospectively from 173 consecutive patients who were scheduled to undergo surgical investigations at the University Hospitals, Leuven, between August 1994 and August 1996. The outcome measure was the histological classification of excised tissues as malignant (including borderline) or benign. METHODS: Age, menopausal status and serum CA 125 levels and sonographic features of the adnexal mass were encoded as variables. The ANNs were trained on a randomly selected set of 116 patient records and tested on the remainder (n = 57). The performance of each model was evaluated using receiver operating characteristic (ROC) curves and compared with corresponding data from an established risk of malignancy index (RMI) and a logistic regression model. RESULTS: There were 124 benign masses, five of borderline malignancy and 44 invasive cancers (of which 29% were metastatic); 37% of patients with a malignant or borderline tumor had stage I disease. The best ANN gave an area under the ROC curve of 0.979 for the whole dataset, a sensitivity of 95.9% and specificity of 93.5%. The corresponding values for the RMI were 0.882, 67.3% and 91.1%, and for the logistic regression model 0.956, 95.9% and 85.5%, respectively. CONCLUSION: An ANN can be trained to provide clinically accurate information, on whether or not an adnexal mass is malignant, from the patient's menopausal status, serum CA 125 levels, and some simple ultrasonographic criteria.  (+info)

The pattern of changes in ovarian stromal and uterine artery blood flow velocities during in vitro fertilization treatment and its relationship with outcome of the cycle. (5/935)

OBJECTIVES: To assess the effect of short-term (2-3 weeks) pituitary suppression and controlled ovarian stimulation on ovarian and uterine artery Doppler measurements during the in vitro fertilization (IVF) treatment cycle and to compare the pattern of these changes between conception and non-conception cycles as well as between patients with normal and those with polycystic ovaries. DESIGN: Prospective observational study of women undergoing IVF treatment. SUBJECTS: Women using the long-treatment buserelin protocol who did not have uterine fibroids, ovarian cysts or endometrioma. METHODS: Serial transvaginal color and pulsed Doppler measurements of ovarian stromal and uterine artery blood flow velocity were carried out in the early follicular phase of the menstrual cycle, on the day of pituitary suppression and on the day of administration of human chorionic gonadotropin (hCG). The main outcome measures were the ovarian stromal and uterine artery blood flow peak systolic velocity (PSV) and pulsatility index (PI). RESULTS: A total of 105 patients were recruited but six patients were excluded from the analysis because they had only one stage of the measurements performed. There was a significant decline in mean ovarian stromal artery PSV after 2-3 weeks of gonadotropin releasing hormone (GnRH) agonist therapy but no effect on ovarian stromal artery PI. The mean uterine artery PSV or PI did not change significantly after 2-3 weeks of GnRH agonist therapy. There was a significantly higher mean ovarian stromal artery PSV in conception cycles compared to non-conception cycles in the early follicular phase and on the day of pituitary suppression, but not on the day of hCG administration. There were no differences between conception and non-conception cycles in the mean uterine artery PSV or PI. Women with polycystic ovaries had a higher mean ovarian artery PSV on all the three occasions of measurement. CONCLUSION: These data suggest that assessment of ovarian blood flow before commencement of gonadotropin stimulation may play a role in assessing cycles likely to result in pregnancy.  (+info)

Diagnostic value of endoscopic ultrasonography-guided fine-needle aspiration cytology of mediastinal masses in patients with intrapulmonary lesions and nondiagnostic bronchoscopy. (6/935)

Several procedures are available for the cytopathological diagnosis of mediastinal lesions. The purpose of this study was to evaluate the diagnostic value of endoscopic ultrasonography (EUS)-guided fine-needle aspiration (FNA) in patients with mediastinal mass lesions/lymph node enlargement. All patients had intrapulmonary lesions on chest X ray and/or CT scan, and inconclusive findings by endobronchial forceps biopsy and/or brush cytology. EUS-guided FNA was performed in 16 patients using a modified oblique forward-viewing gastroscope with an electronic multielement curved linear ultrasound transducer. After the region of interest was localized, a 22-gauge Vilmann-Hancke needle was introduced via the 2-mm biopsy channel. The cytological diagnosis of EUS-guided FNA was conclusive for cancer in 9 patients and in the other 7 patients the aspirated samples revealed a benign lesion. In 10 patients the final diagnosis was cancer, thus EUS-guided FNA was diagnostic for malignancy in all but 1 of the lesions (sensitivity 90.0%). In 1 patient epitheloid cell granuloma was detected by cytological examination of the FNA. Following tuberculostatic treatment the lesions disappeared completely on CT scan and EUS. The overall accuracy in this study amounted to 93.7%. From this and other studies discussed, it is assumed that the procedure is an accurate and safe technique to examine nodular lesions suggestive of metastatic lymph node involvement.  (+info)

Differential diagnosis of small polypoid lesions of the gallbladder: the value of endoscopic ultrasonography. (7/935)

OBJECTIVE: To evaluate the accuracy of endoscopic ultrasonography (EUS) in making a differential diagnosis of small (< or =20 mm) polypoid lesions of the gallbladder. SUMMARY BACKGROUND DATA: Differential diagnosis of these lesions is often difficult using conventional imaging modalities. METHODS: The findings of EUS and transabdominal ultrasonography were retrospectively analyzed in 65 surgical cases of small polypoid lesions (cholesterol polyp in 40, adenomyomatosis in 9, adenoma in 4, and adenocarcinoma in 12). RESULTS: Polypoid lesions exceeding 10 mm suggested malignancy. EUS showed a tiny echogenic spot or an aggregation of echogenic spots with or without echopenic areas in 95% of patients with cholesterol polyps. EUS showed multiple microcysts or comet tail artifact in all adenomyomatosis cases. Adenomas and adenocarcinomas were not associated with the echogenic spots, microcysts, or artifacts. Among adenomas and adenocarcinomas, all sessile lesions were adenocarcinomas. EUS differentiated among polypoid lesions more precisely than ultrasonography (97% vs. 71%). CONCLUSIONS: A tiny echogenic spot or an aggregation of echogenic spots and multiple microcysts or comet tail artifact is pathognomonic for cholesterol polyp and adenomyomatosis, respectively. Polypoid lesions without these findings indicate adenoma or adenocarcinoma on EUS. Routine use of EUS is recommended for differential diagnosis of polypoid gallbladder lesions when ultrasonography shows no signs indicative of either cholesterol polyp or adenomyomatosis.  (+info)

Endoscopic ultrasound guided fine needle aspiration biopsy: a large single centre experience. (8/935)

BACKGROUND: Endoscopic ultrasound guided fine needle aspiration biopsy (EUS-FNA) is a recent innovation in the evaluation of gastrointestinal and pulmonary malignancies. AIMS: To review the experience with EUS-FNA of a large single centre. METHODS: 333 consecutive patients underwent EUS-FNA. Follow up data were available on 327 lesions in 317 patients, including 160 lymph nodes, 144 pancreatic lesions, 15 extraintestinal masses, and eight intramural tumours. RESULTS: A primary diagnosis of malignancy was obtained by EUS-FNA in 62% of patients with clinically suspicious lesions. The overall accuracy of EUS-FNA for the diagnosis of malignancy was 86%, with sensitivity of 84% and specificity of 96%. With respect to lesion types, the sensitivity, specificity, and accuracy were 85%, 100%, and 89% for lymph nodes; 82%, 100%, and 85% for pancreatic lesions; 88%, 100%, and 90% for perirectal masses; and 50%, 25%, and 38% for intramural lesions, respectively. Compared with size and sonographic criteria, EUS-FNA in the evaluation of lymph nodes provided superior accuracy and specificity, without compromising sensitivity. Inadequate specimens were obtained from only six patients, including 3/5 with stromal tumors. Only one complication occurred. CONCLUSIONS: EUS-FNA is safe and can readily obtain tissue specimens adequate for cytopathological diagnoses. Compared with size and sonographic criteria, it is a superior modality for the detection of nodal metastases. While providing accurate diagnosis of pancreatic and perirectal malignancies, results suggest the technique is less useful for intramural lesions.  (+info)

Case Reports in Gastrointestinal Medicine is a peer-reviewed, Open Access journal that publishes case reports and case series focusing on gastroenterology, hepatology, pancreas and biliary, and related cancers.
This article is the second of a two-part publication that expresses the current view of the European Society of Gastrointestinal Endoscopy (ESGE) about endoscopic ultrasound (EUS)-guided sampling, including EUS-guided fine needle aspiration (EUS-FNA) and EUS-guided Trucut biopsy. The first part (the Clinical Guideline) focused on the results obtained with EUS-guided sampling, and the role of this technique in patient management, and made recommendations on circumstances that warrant its use. The current Technical Guideline discusses issues related to learning, techniques, and complications of EUS-guided sampling, and to processing of specimens. Technical issues related to maximizing the diagnostic yield (e. g., rapid on-site cytopathological evaluation, needle diameter, microcore isolation for histopathological examination, and adequate number of needle passes) are discussed and recommendations are made for various settings, including solid and cystic pancreatic lesions, submucosal tumors, and ...
Isolated pancreatic masses are usually primary pancreatic tumours, either ductal adenocarcinoma or neuroendocrine neoplasia, or represent focal chronic pancreatitis [3]. Secondary involvement of the pancreas by extrapancreatic cancer is rare and constitutes less than 3% of all pancreatic resections [2, 4, 25-27], though the rate varies between 3% and 12% of all pancreatic malignancies in autopsy studies [28]. Even though rare, the literature demonstrates the pancreas as a site for metastases from some cancers, especially renal, ovarian, breast, lung, brain and colon [2, 4, 6, 7, 23]. This data was corroborated by the findings of our series as well, with higher prevalence of non-Hodgkins lymphoma, lung, renal, colon and breast cancer.. Patients presenting with pancreatic metastases often have non-specific symptoms. Patients can present with abdominal pain, weight loss, nausea, melaena, jaundice, and gastric outlet obstruction. Abdominal pain was the most frequent symptom in our patients, which ...
Of 8,936 endoscopic ultrasound examinations, 73 repeated procedures were identified, and 24 were excluded.. The 49 initial endoscopic ultrasound procedures were done in Indiana or another state, by one of 15 physicians in private practice, or at a teaching hospital.. The researchers performed an endoscopic ultrasound-guided fine-needle aspiration during an initial endoscopic ultrasound in 21 patients.. This method was not attempted in 14 patients.. The principle indication for a repeated endoscopic ultrasound in 35 patients was for an endoscopic ultrasound fine-needle aspiration after the initial tissue sampling was benign, nondiagnostic, or not done.. The researchers noted that a second endoscopic ultrasound had no clinical impact in 37% of patients.. The team found that in the remaining 63% of patients, a repeated endoscopic ultrasound provided a new or changed clinical diagnosis.. Dr DeWitts team commented, In this study, a repeated endoscopic ultrasound at a tertiary-referral center had a ...
The results of this study show that EUS with FNA is an accurate method for diagnosing sarcoidosis in an unselected group of patients with mediastinal lymphadenopathy of unknown origin. The sensitivity and specificity were 89% and 96% after exclusion of the indefinite cases in both groups. These values must be appreciated in the context of the difficult and often incomplete clinical diagnosis of sarcoidosis.. Mediastinal lymphadenopathy represents a diagnostic challenge because of the variety of potential pathological aetiologies and the difficulty of access for tissue sampling. Different diagnostic modalities have been used for evaluating mediastinal lymphadenopathy of undetermined origin including CT, MRI, bronchoscopy with TBB, mediastinoscopy, and thoracotomy. Evaluation of the mediastinum using EUS-FNA has been found to be useful for a number of indications. Several publications have shown that EUS-FNA establishes the diagnosis in a high percentage of patients with mediastinal ...

Several extrathoracic tumors metastasize to the mediastinum. Mediastinoscopy is the standard method to obtain tissue proof of mediastinal spread, but drawbacks are its invasiveness, requirement for general anesthesia and costs. Transesophageal endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is indicated in lung cancer staging guidelines as a minimally invasive alternative for surgical staging. The diagnostic values in patients with suspected mediastinal metastases and various (previous) extrathoracic malignancies were assessed. ...

In addition, the prognosis of our patients with EUS non-traversable EC may have been further worsened by the limited EUS assessment of EC stage. EUS is a standard locoregional staging modality for EC, demonstrating high T (80% to 90%) and N staging accuracy (70% to 80%) that is clearly superior to CT and magnetic resonance imaging [3,4]. However, the accuracy of EUS decreases significantly when an echoendoscope cannot pass through EC. Staging accuracy of EUS is reportedly 46% in EUS non-traversable EC (vs. 92% in EUS traversable EC) and correct preoperative T stage was obtained using EUS only in 30.8% of patients with high-grade EC stenosis (vs. 81% of patients with less severe EC stenosis) [6,22]. A previous study reported that 9.9% of patients with distant metastatic nodes were found on EUS after EC stenosis dilation [23]. Another study on the effects of EUS after dilation of EC stenosis reported that EUS detected additional cases of advanced diseases in 19% of patients, including celiac node ...

Objectives: To investigate quantitative and qualitative EUS parameters of left-sided colonic cancers with contrast enhanced EUS imaging.. Design: A prospective cohort study. Methods: When EUS staging has been performed in the cohort of study 2, further evaluation of tumour perfusion will be done by low-mechanical contrast enhanced endoscopic ultrasound (CE-EUS). Power Doppler vascularity index will be calculated and used as a measure of tumour perfusion. The volume of tumour perfusion has previously shown a strong correlation with the vascular density. The perfusion of tumour tissue per cm3 (automated pixel analysis) will be compared with histologically determined vascular density. The study is explorative and no sample size calculation is possible based on present literature.. Outcome: Outcome measures will be endoscopic ultrasound perfusion parameters correlated to histopathological vascular characteristics of left-sided colonic cancers (e.g. micro vessel density measured by CD31 staining and ...

A 19 gauge needle in nitinol (Flex needle) has been recently become available for EUS guided procedure.. The use of nitinol should guarantee a better needle flexibility with a theoretical advantage on the use of this needle for lesions that need to be sampled through the duodenum. Moreover, samples for histologic examination seems to be easy to interpret than cytologic ones allowing evaluate of the overall architecture of the tissue, better performance of immunohistochemical staining, and may be of additional value to perform tissue profiling that in the future will be very important to guide individualized therapies. The existing data on the performance of the Flex needle for EUS-guided transduodenal biopsy are coming form a single study performed in one single center. Thus, the reproducibility of these results is unknown and multicenter prospective studies are warranted to answer this important question. ...
Endoscopic ultrasonography (EUS) is the single best modality for staging esophageal cancer with respect to depth of tumor infiltration and extent of lymph node involvement using the TNM classification system. The accuracy of EUS for staging patients with esophageal carcinoma who subsequently underwent surgery for confirmation ranged from 59% to 92% (with a mean of 84% in 1154 patients); the accuracy for N staging ranged from 50% to 90% (with a mean of 77% in 1035 patients). Endosonography is superior to CT in the T and N staging of disease. However, EUS is not a sensitive tool for diagnosing tumor involvement of the trachea and bronchial tree, because these structures contain air. Bronchoscopy should be used for the staging of proximal esophageal cancers. If esophageal cancers obstruct the lumen and the EUS endoscope cannot be advanced through, tumor staging is incomplete. EUS employs the technology of endoscopy and internally placed high-frequency ultrasound waves to visualize the ...

EUS is an advanced endoscopic technique. Very few specialists and endoscopists undergo additional training after specialization to do this properly. Typically, it takes about an additional 1-2 years of dedicated EUS training after completing specialist and general endoscopy training in order to perform EUS competently. There are various levels of difficulty in EUS. Most EUS specialists are able to perform routine cases such as simple diagnostic evaluation and FNA. However, only top EUS experts are able to perform difficult cases successfully. It is important to ensure that the doctor performing the EUS has the correct level of expertise to match the difficulty of the case.. EUS is safe when performed by properly trained doctors. The risk of diagnostic EUS is equivalent to a simple gastroscopy. Complications and failures increase significantly when EUS is performed by Inadequately trained doctors or those with insufficient cases to maintain their skill. Hence, it is important to ensure that the ...
Endoscopic US (endosonography), using a high-resolution 20MHz transducer, has the potential of becoming the most important imaging modality in esophageal cancer staging and evaluating other intramural lesions. Tumor extension to regional nodes can be detected. The current trend is that endosonography influences patient management, often toward less costly, less risky, and less invasive procedures. Endoluminal US data can provide 3D images, potentially aiding staging, but this technique is too new to draw conclusions. Fine-needle aspiration biopsy using endoscopic US guidance is feasible ...
Results The number of EUS procedures rose from 54 in 2002 to 287 in 2013. EUS FNA started in 2006 with the purchase of a linear echoendoscope which was associated with increasing number of EUS. There was a further increase in numbers in 2011 with the appointment of an additional consultant with an interest in EUS. There was a dip in total numbers 2008-2009 due to technical issues. Overall, there was a significant increase in the number of PB EUS comparing 2002 with 2013 (9/54 vs. 207/287, p , 0.0001). There was a significant increase in the number of FNA performed comparing 2002 with 2013 (0/54 vs 48/287, p = 0.0006). EUS-FNA sensitivity for solid pancreatic lesions was 61.5%, for non-pancreatic lesions it was 66% but specificity was 100% in both groups of lesions. In solid pancreatic masses, diagnostic cytology was associated with increased numbers of passes into the lesion compared to non-diagnotic cytology (median 4 passes vs. median 2 passes, p = 0.001). There was no difference number of ...
An endoscopic ultrasound (EUS) is a test to look at the inside of your gastrointestinal (GI) tract. Its commonly used to look for cancers or growths in the esophagus, stomach, pancreas, liver, and rectum.
The ability to look inside the body is a powerful tool for diagnosing medical conditions.. Traditional imaging techniques such as X-ray, ultrasound, magnetic resonance imaging (MRI), and others allow doctors to observe certain conditions from the outside, looking in.. However, an endoscopic ultrasound (EUS) is a procedure that allows doctors to obtain images and information from the inside.. Specifically, this medical procedure combines endoscopy (the insertion of a long flexible tube via the mouth or rectum to visualize the digestive tract) with an ultrasound examination (a diagnostic imaging test that uses high-frequency sound waves to produce images or pictures of internal organs and structures inside the body). Doctors use EUS to obtain images of the internal organs in the chest and abdomen, as well visualize the walls of these organs, or to look at adjacent areas such as lymph nodes. Combined with Doppler imaging (another form of ultrasound), nearby blood vessels can also be ...
The consultant uses an endoscope (long, flexible telescope) with a miniature ultrasound probe attached. This is passed through the mouth, down the oesophagus into the stomach and duodenum. The ultrasound probe can give highly detailed images of the wall of the oesophagus, stomach and duodenum as well as the adjacent organs - gallbladder, pancreas and bile duct.. EUS can be used to take a tissue sample (biopsy), using a fine needle that is passed through the endoscope.This is then sent to the laboratory for analysis. This technique can assist in the diagnosis of enlarged abdominal lymph nodes, cysts or tumours.. Endoscopic ultrasound may be helpful in a variety of clinical scenarios:. ...
Endoscopic ultrasound (EUS) uses a specialized endoscope-a long, flexible, lighted tube-equipped with a small ultrasound probe, which emits sound waves.
There are situations in which a diagnosis of IgG4-RD is under consideration on clinical grounds and where histopathological examination of accessible tissue that may not be clinically or radiologically involved in the disease process may be requested in order to attempt to support the diagnosis. This is often the case in patients with suspected AIP where endoscopic ultrasound guided aspiration and/or biopsy of a pancreatic mass can be challenging and yields insufficient material for analysis. The extent to which histopathological features and IgG4+ plasma cell counts or IgG4+ to IgG ratios can be used in this context is currently uncertain. Examples of tissues that may undergo histopathological examination in this and related situations include the ampulla of Vater, duodenum, bile duct, gallbladder and the colon.. Ampullary or distal duodenal biopsies may be taken when a diagnosis of AIP is being considered, even when the mucosa appears normal on endoscopic examination. Associations have been ...

OBJECTIVES: Contrast-enhanced harmonic endoscopic ultrasonography (CEH-EUS) has been used to diagnose solid pancreatic lesions (SPLs). The aim of this study was to investigate the efficacy of CEH-EUS-guided fine-needle aspiration (CEH-EUS-FNA) compared with that of conventional EUS-FNA for the diagnosis of SPLs.. METHODS: Forty patients with solid pancreatic lesions who visited Fukushima Medical University between September 2013 and June 2014 were recruited for this prospective study. Twenty patients underwent CEH-EUS-FNA, and 20 patients underwent conventional EUS-FNA. The sampling rate, sensitivity, accuracy, and number of needle passes required to obtain sufficient samples were compared between the two groups.. RESULTS: Patient characteristics, sampling rate, accuracy, and sensitivity were not significantly different between the two groups. The final diagnosis of patients who underwent CEH-EUS-FNA was pancreatic cancer in 19 and intraductal papillary mucinous carcinoma in one. Nineteen ...

The characteristic finding was an elliptical or tortuous anechoic lesion in the submucosal layer that extended to the outer side of the gastric wall. There were no intramural changes suggestive of deep ulcer beyond the Ul‐2. An abnormally large submucosal vessel was observed within 4 cm of the site of bleeding. This vessel was present even in the remnant stomach of a patient who required emergency surgery because an attempt to treat massive bleeding with endoscopic hemostasis failed. These endosonographic findings suggest that Dieulafoys lesion patients risk rebleeding due to shallow ...

Scarless surgery is an innovative and promising technique that may herald a new era in surgical procedures. We have created a navigation system, named IRGUS, for endoscopic and transgastric access interventions and have validated it in in vivo pilot studies. Our hypothesis is that endoscopic ultrasound procedures will be performed more easily and efficiently if the operator is provided with approximately registered 3D and 2D processed CT images in real time that correspond to the probe position and ultrasound image. Materials and Methods: The system provides augmented visual feedback and additional contextual information to assist the operator. It establishes correspondence between the real-time endoscopic ultrasound image and a preoperative CT volume registered using electromagnetic tracking of the endoscopic ultrasound probe position. Based on this positional information, the CT volume is reformatted in approximately the same coordinate frame as the ultrasound image and displayed to the ...
An accurate understanding of the position of the target lesion is essential to improve the diagnostic rate of TBNA, because failure to place the needle within the lesion is the leading cause of a low biopsy yield. The advent of new technologies such as EBUS and CT fluoroscopy has led to the concept of integration with TBNA to improve the diagnostic yield. Although EBUS images show target lesions beyond the airway, needle penetration of the target lesion could not be proved by EBUS using a single-channel bronchoscope. To confirm whether the target lesion was aspirated, rapid on-site cytopa-thology was needed immediately after aspiration. In this study, high diagnostic rates were established by EBUS-D without requiring rapid on-site cytopathology because the real-time EBUS image confirmed that the TBNA needle was within the lesion, in which it offered as a hyperechoic point. An advantage of EBUS-D is that if the TBNA needle is not placed correctly on the first penetration, relocation of the ...
Most of pancreatic masses are represented by neoplastic processes, primarily ductal adenocarcinoma and less frequently neuroendocrine tumor, lymphoma and metastasis. On the contrary, non neoplastic lesions are represented by chronic, autoimmune pancreatitis and cysts [1, 2]. Pancreatic cancer is the fourth and fifth most common cancer in men and women respectively [3]. Due to local invasion or distant metastasis, only 15-20% of patients are surgical candidates at presentation. Among them, the 5-year survival rate is only 10-15% [4]. About 70% of pancreatic cancers develop in the head while 10-20% in the body and tail [5]. In many cases, pancreatic cancer is diagnosed in the advanced stage of the disease and at this point the tumor cannot be submitted to surgical resection. In fact, at the moment of diagnosis, 52% patients show distant disease and 26% have regional spread [6]. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a rapid, safe, cost-effective and accurate technique to evaluate
Antibiotics are not generally required before or after EUS examinations. However, your doctor might prescribe antibiotics if you are having specialized EUS procedures, such as to drain a fluid collection or a cyst using EUS guidance.. Practices vary among doctors, but for an EUS examination of the upper gastrointestinal tract, some endoscopists spray your throat with a local anesthetic before the test begins. Most often you will receive sedatives intravenously to help you relax. You will most likely begin by lying on your left side. After you receive sedatives, your endoscopist will pass the ultrasound endoscope through your mouth, esophagus and stomach into the duodenum. The instrument does not interfere with your ability to breathe. The actual examination generally takes less than 60 minutes. Many do not recall the procedure. Most patients consider it only slightly uncomfortable, and many fall asleep during it. An EUS examination of the lower gastrointestinal tract can often be performed ...

Recurrent pancreatitis associated with pancreatic strictures requires treatment with endoscopic retrograde pancreatography (ERP), but it is sometimes technically unsuccessful. Endoscopic ultrasound-guided pancreatic drainage (EUS-PD) was developed as an alternative to a surgical approach after failed ERP; however, the indications for EUS-PD are unclear. In this study, we evaluated the outcomes of EUS-PD and established the indications for EUS-PD. Methods. A total of 15 patients had indications for EUS-PD for recurrent pancreatitis due to pancreatic strictures. There were eight patients with ...
Contrast enhancing media has been mainly used in enhancing the color doppler signal so far. Since conventional abdominal ultrasonography can not detect the small particles of contrast enhancer due to its low frequency range, it was rarely used in B-mode imaging. However, endoscopic ultrasonography (EUS) with a high frequency range can detect the particles and produce a contrast-enhancing effect when injecting a contrast enhancer such as Levovist. Gastric submucosal tumor shows various ultrasonograpic features, depending on histopathology, but its differential diagnosis is limited. We experienced two cases where the enhancing features on EUS for submucosal tumors were recognized by using Levovist and this helped preoperative prediction of differential diagnosis. The use of contrast enhancer such as Levovist during EUS of submucosal tumor enables us to learn the hemodynamic features of the tumor. Therefore, the differential diagnosis and prediction of the characteristics of the submucosal tumor ...

To provide criteria for the differential diagnosis of serous cystic neoplasms (SCNs) and mucinous cystic neoplasms (MCNs) by analyzing the imaging features of these two neoplasms by endoscopic ultrasound (EUS). From April 2015 to December 2017, a total of 69 patients were enrolled in this study. All patients were confirmed to have MCNs (31 patients) or SCNs (38 patients) by surgical pathology. All patients underwent EUS examination. The observation and recorded items were size, location, shape, cystic wall thickness, number of septa, and solid components. Head/neck location, lobulated shape, thin wall and | 2 septa were the specific imaging features for the diagnosis of SCNs. When any two imaging features were combined, we achieved the highest area under the curve (Az) (0.824), as well as the appropriate sensitivity (84.2%), specificity (80.6%), positive predictive value (PPV) (84.2%), and negative predictive value (NPV) (80.6%).

Patients with esophageal high grade dysplasia or mucosal esophageal cancer can he successfully treated hy endoscopy. We performed a systematic review of the literature to determine whether endoscopic ultrasound (EUS) correctly predicts the T-stage of early esophageal cancers, compared with pathology specimens obtained by using endoscopic mucosal resection (EMR) or surgery. METHODS: Standard systematic review methods were used w perform reference searches, determine eligibility, abstract data, and analyze data. \When possible, individual patient-level data were abstracted, in addition to publication- level aggregate data. RESULTS: Twelve studies had sufficient information to abstract and review for quality; 8 had individual patient-level data (n = 132). Compared with surgical or EMR pathology staging, EUS had T-stage concordance of 65%, including all studies (n = 12), but only 56% concordance when limited to individual patient-level data.

Endoscopy and Endoscopic Ultrasound Conference is for the researchers, scientists, scholars, engineers, academic, scientific and university practitioners to present research activities that might want to attend events, meetings, seminars, congresses, workshops, summit, and symposiums.
Background and Aim: A recently carried out randomized controlled trial showed the benefit of a novel 20-G fine-needle biopsy (FNB) over a 25-G fine-needle aspiration (FNA) needle. The current study evaluated the reproducibility of these findings among expert academic and non-academic pathologists. Methods: This study was a side-study of the ASPRO (ASpiration versus PROcore) study. Five centers retrieved 74 (59%) consecutive FNB and 51 (41%) FNA samples from the ASPRO study according to randomization; 64 (51%) pancreatic and 61 (49%) lymph node specimens. Samples were re-reviewed by five expert academic and five non-academic pathologists and rated in terms of sample quality and diagnosis. Ratings were compared between needles, expert academic and non-academic pathologists, target lesions, and cytology versus histological specimens. Results: Besides a higher diagnostic accuracy, FNB also provided for a better agreement on diagnosing malignancy (ĸ = 0.59 vs ĸ = 0.76, P , 0.001) and classification ...

The research team evaluated 69 patients referred for endoscopic ultrasound because of thickened gastric folds on CT between 2001 and 2003. The average age of the participants was 57 years, and 49% were male.. Of the participants included, 51% were asymptomatic, 57% had normal upper endoscopy, and 70% had normal EUS. A single physician questioned, examined, and performed upper endoscopy followed by EUS in all patients.. The researchers assessed upper endoscopy and EUS findings, and predictors of abnormal EUS. If upper endoscopy was abnormal, EUS was abnormal in 70% of cases. The team found that if upper endoscopy was normal, the EUS was normal in 100% of cases. Multivariate analysis revealed that neither age, gender, presence of abdominal symptoms nor alarm symptoms predicted abnormal EUS. Dr Lams team concluded that, When CT shows gastric wall thickening, normal upper endoscopy is strongly associated with normal EUS.. Abnormal upper endoscopy is associated with abnormal EUS in 70% of ...
Aceptado: 10-05-05.. Correspondencia: Juan J. Vila Costas. Servicio de Aparato Digestivo. Hospital de Navarra. C/ Irunlarrea, 3. 31008 Pamplona. e-mail: [email protected] INTRODUCTION. Endoscopic ultrasonography or echoendoscopy integrates endoscopic examination and ultrasound imaging in one single piece of equipment. Three endosonographic examination systems are primarily available (1):. -Radial system: using a mechanic rotary or electronic device, it obtains 360º ultrasonographic images perpendicular to the transducers axis, with frequencies available including 5, 7.5, 12, and 20 MHz. It allows neither color Doppler studies, nor deep tissue sampling for histological examination. From this point on, this technique will be referred to as EUS.. -Sectorial system: it allows ultrasonographic examination using 100º longitudinal sections, which are obtained through an oblique-beam electronic transducer with 5 and 7.5 MHz frequencies. It allows both qualitative and quantitative color Doppler ...
