Colon and rectal anastomoses do not require routine drainage: a systematic review and meta-analysis. (1/1718)

OBJECTIVE: Many surgeons continue to place a prophylactic drain in the pelvis after completion of a colorectal anastomosis, despite considerable evidence that this practice may not be useful. The authors conducted a systematic review and meta-analysis of randomized controlled trials to determine if placement of a drain after a colonic or rectal anastomosis can reduce the rate of complications. METHODS: A search of the Medline database of English-language articles published from 1987 to 1997 was conducted using the terms "colon," "rectum," "postoperative complications," "surgical anastomosis," and "drainage." A manual search was also conducted. Four randomized controlled trials, including a total of 414 patients, were identified that compared the routine use of drainage of colonic and/or rectal anastomoses to no drainage. Two reviewers assessed the trials independently. Trial quality was critically appraised using a previously published scale, and data on mortality, clinical and radiologic anastomotic leakage rate, wound infection rate, and major complication rate were extracted. RESULTS: The overall quality of the studies was poor. Use of a drain did not significantly affect the rate of any of the outcomes examined, although the power of this analysis to exclude any difference was low. Comparison of pooled results revealed an odds ratio for clinical leak of 1.5 favoring the control (no drain) group. Of the 20 observed leaks among all four studies that occurred in a patient with a drain in place, in only one case (5%) did pus or enteric content actually appear in the effluent of the existing drain. CONCLUSIONS: Any significant benefit of routine drainage of colon and rectal anastomoses in reducing the rate of anastomotic leakage or other surgical complications can be excluded with more confidence based on pooled data than by the individual trials alone. Additional well-designed randomized controlled trials would further reinforce this conclusion.  (+info)

Is early post-operative treatment with 5-fluorouracil possible without affecting anastomotic strength in the intestine? (2/1718)

Early post-operative local or systemic administration of 5-fluorouracil (5-FU) is under investigation as a means to improve outcome after resection of intestinal malignancies. It is therefore quite important to delineate accurately its potentially negative effects on anastomotic repair. Five groups (n = 24) of rats underwent resection and anastomosis of both ileum and colon: a control group and four experimental groups receiving daily 5-FU, starting immediately after operation or after 1, 2 or 3 days. Within each group, the drug (or saline) was delivered either intraperitoneally (n = 12) or intravenously (n = 12). Animals were killed 7 days after operation and healing was assessed by measurement of anastomotic bursting pressure, breaking strength and hydroxyproline content. In all cases, 5-FU treatment from the day of operation or from day 1 significantly (P<0.025) and severely suppressed wound strength; concomitantly, the anastomotic hydroxyproline content was reduced. Depending on the location of the anastomosis and the route of 5-FU administration, even a period of 3 days between operation and first dosage seemed insufficient to prevent weakening of the anastomosis. The effects of intravenous administration, though qualitatively similar, were quantitatively less dramatic than those observed after intraperitoneal delivery. Post-operative treatment with 5-FU, if started within the first 3 days after operation, is detrimental to anastomotic strength and may compromise anastomotic integrity.  (+info)

Right atrial bypass grafting for central venous obstruction associated with dialysis access: another treatment option. (3/1718)

PURPOSE: Central venous obstruction is a common problem in patients with chronic renal failure who undergo maintenance hemodialysis. We studied the use of right atrial bypass grafting in nine cases of central venous obstruction associated with upper extremity venous hypertension. To better understand the options for managing this condition, we discuss the roles of surgery and percutaneous transluminal angioplasty with stent placement. METHODS: All patients had previously undergone placement of bilateral temporary subclavian vein dialysis catheters. Severe arm swelling, graft thrombosis, or graft malfunction developed because of central venous stenosis or obstruction in the absence of alternative access sites. A large-diameter (10 to 16 mm) externally reinforced polytetrafluoroethylene (GoreTex) graft was used to bypass the obstructed vein and was anastomosed to the right atrial appendage. This technique was used to bypass six lesions in the subclavian vein, two lesions at the innominate vein/superior vena caval junction, and one lesion in the distal axillary vein. RESULTS: All patients except one had significant resolution of symptoms without operative mortality. Bypass grafts remained patent, allowing the arteriovenous grafts to provide functional access for 1.5 to 52 months (mean, 15.4 months) after surgery. CONCLUSION: Because no mortality directly resulted from the procedure and the morbidity rate was acceptable, this bypass grafting technique was adequate in maintaining the dialysis access needed by these patients. Because of the magnitude of the procedure, we recommend it only for the occasional patient in whom all other access sites are exhausted and in whom percutaneous dilation and/or stenting has failed.  (+info)

Endovascular stent graft repair of aortopulmonary fistula. (4/1718)

Two patients who had aortopulmonary fistula of postoperative origin with hemoptysis underwent successful repair by means of an endovascular stent graft procedure. One patient had undergone repeated thoracotomies two times, and the other one time to repair anastomotic aneurysms of the descending aorta after surgery for Takayasu's arteritis. A self-expanding stainless steel stent covered with a Dacron graft was inserted into the lesion through the external iliac or femoral artery. The patients recovered well, with no signs of infection or recurrent hemoptysis 8 months after the procedure. Endovascular stent grafting may be a therapeutic option for treating patients with aortopulmonary fistula.  (+info)

Factors influencing the development of vein-graft stenosis and their significance for clinical management. (5/1718)

OBJECTIVES: To assess the influence of clinical and graft factors on the development of stenotic lesions. In addition the implications of any significant correlation for duplex surveillance schedules or surgical bypass techniques was examined. PATIENTS AND METHODS: In a prospective three centre study, preoperative and peroperative data on 300 infrainguinal autologous vein grafts was analysed. All grafts were monitored by a strict duplex surveillance program and all received an angiogram in the first postoperative year. A revision was only performed if there was evidence of a stenosis of 70% diameter reduction or greater on the angiogram. RESULTS: The minimum graft diameter was the only factor correlated significantly with the development of a significant graft stenosis (PSV-ratio > or = 2.5) during follow-up (p = 0.002). Factors that correlated with the development of event-causing graft stenosis, associated with revision or occlusion, were minimal graft diameter (p = 0.001), the use of a venovenous anastomosis (p = 0.005) and length of the graft (p = 0.025). Multivariate regression analysis revealed that the minimal graft diameter was the only independent factor that significantly correlated with an event-causing graft stenosis (p = 0.009). The stenosis-free rates for grafts with a minimal diameter < 3.5 mm, between 3.5-4.5 and > or = 4.5 mm were 40%, 58% and 75%, respectively (p = < 0.05). Composite vein and arm-vein grafts with minimal diameters > or = 3.5 mm were compared with grafts which consisted of a single uninterrupted greater saphenous vein with a minimal diameter of < 3.5 mm. One-year secondary patency rates in these categories were of 94% and 76%, respectively (p = 0.03). CONCLUSIONS: A minimal graft diameter < 3.5 mm was the only factor that significantly correlated with the development of a graft-stenosis. However, veins with larger diameters may still develop stenotic lesions. Composite vein and arm-vein grafts should be used rather than uninterrupted small caliber saphenous veins.  (+info)

Cylindrical or T-shaped silicone rubber stents for microanastomosis--technical note. (6/1718)

The ostium of the recipient artery and the orifice of the donor artery must be clearly visualized for the establishment of microvascular anastomosis. Specially designed colored flexible cylindrical or T-shaped silicone rubber stents were made in various sizes (400 or 500 microns diameter and 5 mm length) and applied to bypass surgery in patients with occlusive cerebrovascular disease such as moyamoya disease and internal carotid artery occlusion. The colored flexible stents facilitated confirmation of the ostium of the artery even in patients with moyamoya disease and allowed precise microvascular anastomosis without problems caused by the stent.  (+info)

Subclavian artery resection and reconstruction for thoracic inlet cancers. (7/1718)

PURPOSE: We previously described an original transcervical approach to resect primary or secondary malignant diseases that invade the thoracic inlet (TI). The purpose of this study was to evaluate the technical aspects and long-term results of the resection and revascularization of the subclavian artery (SA). METHODS: Between 1986 and 1998, 34 patients (mean age, 49 years) underwent en bloc resection of TI cancer that had invaded the SA. The surgical approach was an L-shaped transclavicular cervicotomy in 33 patients. In 14 of these patients, this approach was associated with a posterolateral thoracotomy (n = 10) or a posterior midline approach (n = 4). In one patient, the procedure was achieved with a single posterolateral thoracotomy approach. An end-to-end anastomosis was performed in 16 patients. In one patient, a subclavian-left common carotid artery transposition was performed. In one other patient, an end-to-end anastomosis was performed between the proximal innominate artery and the SA. The right carotid artery was transposed into the SA in an end-to-side fashion. In 16 patients, prosthetic revascularization with a polytetrafluoroethylene graft was performed. Thirty-three patients underwent postoperative radiation therapy. RESULTS: There were no cases of perioperative death, neurologic sequelae, graft infections or occlusions, or limb ischemia. There were two delayed asymptomatic polytetrafluoroethylene graft occlusions at 12 and 31 months. The 5-year patency rate was 85%. During this study, 20 patients died: 18 died of tumor recurrence (5 local and systemic and 13 systemic), one of respiratory failure, and one of an unknown cause at 74 months. The overall 5-year survival rate was 36%, and the 5-year disease-free survival rate was 18%. CONCLUSION: Tumor arterial invasion per se should not be a contraindication to TI cancer resection. This study shows that cancers that invade the SA can be resected through an L-shaped transclavicular cervicotomy, with good results with a concomitant revascularization of the SA.  (+info)

Laparoscopic aortofemoral bypass grafting: human cadaveric and initial clinical experiences. (8/1718)

PURPOSE: Postoperative complications are mainly related to the surgical trauma derived from the extensive abdominal incision and dissection after a conventional aortofemoral bypass grafting procedure. In an attempt to reduce postoperative complications, a concept of video-endoscopic vascular surgery on the infrarenal aortoiliac artery has been developed. On the basis of our experience with the practicability of video-endoscopic vascular surgery in the pelvic region in an animal study and in a pilot study of human cadavers, the purpose of this report was to describe three different methods that we evaluated on human cadavers and that we partly applied to patients. METHODS: In this experimental study, three different approaches were used to perform video-endoscopic aortofemoral bypass grafting. We performed an observational trial on human corpses (n = 24) with the transabdominal-retroperitoneal approach (TARA), the extraperitoneal approach (EPA), and the transabdominal left paracolic approach (TAPA). The EPA also was applied to patients with aortoiliac occlusive diseases. RESULTS: The TARA on cadavers (n = 4) soon was abandoned because it caused a burdensome sliding of the intestine into the operative field adjacent to the renal vessels, particularly in cases with obese subjects. In comparison, the TAPA (n = 6) with right-sided positioning of the patient retained the intestine in the right upper abdomen throughout the procedure. Until a surgeon actually is acquainted with the anatomic landmarks and the laparoscopic preparation technique, the EPA (n = 14) is a challenging procedure that necessitates thorough training. As with the TAPA, the EPA represents a procedure that reveals constant exposure of the operating field, even in cases with obese subjects. In the clinical observational study (n = 7), aortobifemoral bypass grafting was achieved totally laparoscopically with the EPA. The mean operating time was 6.5 hours and ranged from 3 to 10 hours. Blood transfusions were necessary after surgery in three patients (range, 1 to 3 red packed blood cells). One patient, who had had occlusion of the inferior mesenteric artery, died of ischemic colitis at postoperative day 10. The other patients had uneventful postoperative courses with minor wound discomfort. CONCLUSION: Laparoscopic vascular surgery seems to be a promising procedure to minimize postoperative complications. On the basis of our experience, we do not favor the TARA. Because it necessitates steep Trendelenburg positioning to displace intra-abdominal organs, the TARA is not an appropriate approach, particularly in obese and cardiopulmonary frail cases. Contrarily, the TAPA and the EPA deliver potentially better results in terms of exposing the operative field and thus reducing operating time and perioperative morbidity rates. A prospective cadaveric and clinical trial may be justified to further evaluate the use of these surgical techniques.  (+info)

A cuff is used to provide a form for curing fluid about the exterior of an end-to-end anastomosis site. The cuff includes a port through which fluid may be injected to reach an interior space defined between the exterior of tissue at the anastomosis site and the inner surface of the cuff. A circular stapler may be used as a mandrel for the cuff and fluid. Alternatively, inflatable balloons may be used as a mandrel. The curing fluid may comprise a mixture of fibrin and thrombin.

The experiments in this report were designed to evaluate the effect of superficial temporal-middle cerebral artery (STA-MCA) anastomosis on the course of middle cerebral artery (MCA) occlusion by emboli while avoiding a vessel clipping technique as well as the use of long-acting barbiturate anesthesia. Dogs were divided into 3 general groups: A) embolus placement 1 h following anastomosis; B) embolus placement 5 h prior to anastomosis; C) control group without anastomosis. Anastomosis prior to MCA occlusion has a favorable clinical effect and reduces the size of an infarction. Anastomosis 5 h after embolus placement is deleterious unless other therapeutic modalities can be shown to delay the course of infarction. ...
Patient was in the right lateral decubitus position with the lower body slightly tilted to the left, and a left thoracoabdominal incision was performed. The cardiopulmonary bypass was established by a venous cannula placed in the right atrium through the left femoral vein and 2 arterial return cannulas inside both femoral artery and ascending aorta. If the proximal thoracic descending aorta was not involved by the aneurysm and was long enough for both clamping and anastomosis (usually Crawford extent III TAAA), proximal aortic anastomosis was performed under mild hypothermic cardiopulmonary bypass and beating heart. otherwise, it was performed using an open technique with profound hypothermic circulatory arrest.. During our modified multiple branched graft replacement of TAAA, the proximal aortic anastomosis was performed first. After a proximal aortic clamp was placed just distal to the left subclavian artery or profound hypothermic circulatory arrest was established, a distal aortic clamp was ...
Distal anastomosis devices and associated methodology are described herein. Connector and connector components as well as tools associated therewith are disclosed. The connectors are preferably adapted to produce an end-to-side anastomosis at a graft/coronary artery junction. A fitting alone, or a fitting in combination with a collar may be used as a connector. Each fitting may be deployed by deflecting its shape to provide clearance for a rear segment that rotates about adjoining hinge section(s) so to fit the connector within an aperture formed in a host vessel. Upon return to a substantially relaxed position, a rear segment anchors the fitting it in place. The distal fitting may include additional side features for interfacing with the host vessel/coronary artery. The collar may include features complimentary to those of a fitting and provisions for strain relief and securing the graft vessel.

Methods and devices use magnetic force to form a magnetic port in a hollow body. Additional methods and devices form anastomoses between two or more hollow bodies. First and second anastomotic securing components create a fluid-tight connection between the lumens of the hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created without using suture or any other type of mechanical fasteners, although mechanical attachment structure may be used in conjunction with the magnetic attachment. The securing components have magnetic, ferromagnetic or electromagnetic properties and may include one or more materials, for example, magnetic and nonmagnetic materials arranged in a laminated structure. The system of anastomotic securing components may be used in many different applications including the treatment of cardiovascular disease, peripheral vascular disease, forming AV shunts, etc. The system may be sized and configured for forming an anastomosis in or between a specific hollow body,
Head and neck anastomosis techniques present common aspects with any type of anastomosis but their localisation at the junction of the respiratory and digestive tracts makes them often delicate to perform.

The main types of flaps also used for this purpose are highlighted. We then review the cases observed during the 5 last years in our department, type and technique of surgery used. In this general review, we illustrate our stand point although aware of the multiple variants favoured by different schools. ...
INTRODUCTION. Conventional vascular anastomosis requires extensile exposure, circumferential dissection and temporary occlusion of the vessels. This technique was initially described by Alexis Carrel, in 1902[1], and despite several technical improvements it has remained basically the same.. Several devices for sutureless anastomosis were developed since that time, as grafts with rings[2], connectors[3], clips[4] and even magnets[5].. In complex aortic surgeries, the time to perform an anastomosis is related to ischemic and reperfusion injuries and can lead to renal failure, mesenteric ischemia and systemic inflammatory response. Thus, is advisable to simplify and shorten this period of the surgery.. In 2008, Lachat et al.[6] described a technique of sutureless anastomosis by telescoping a stent graft (Viabahn, W. L. Gore & Associates, Flagstaff, AZ) in order to facilitate complex vascular reconstruction in debranching procedures for thoracoabdominal aneurysms. The advantages of this technique ...
An apparatus for anastomosing an organ of a subject to be anastomosed such as patient comprises a pair of magnets being disposed to predetermined sites or regions of organs of the subject each other so as to be opposed through wall portions of the respective organs, the magnets being adsorbed to each other so as to form an anastomosis site having a through hole for making communication between the organ walls, a flexible soft guide wire detachably mounted to at least one of the paired magnets, and a guide tube inserted into a body of the subject with the guide wire being inserted therein, the guide tube coming into contact with a guide wire mount surface of the one of magnets so as to support the one magnet when the guide wire is removed from the one magnet and the guide tube being inserted into the through hole of the anastomosis site to maintain formation of the through hole.
A method and devices are provided for performing end-to-side anastomoses between the severed end of a first hollow organ and the side-wall of a second hollow organ utilizing transluminal approach with endoscopic assistance, wherein the first and second hollow organs can be secured utilizing a biocompatible glue, clips or by suturing. In an alternative embodiment, the method utilizes a modified cutter catheter which is introduced into the first hollow organ in combination with a receiver catheter which is introduced into the second hollow organ. The distal end of the receiver catheter includes a receiver cavity and a selectively activatable magnetic material. The magnetic material is selected so that it will interact with a magnetically susceptible material disposed in the distal end of the modified cutter catheter when the modified cutter catheter is disposed in proximity to the proposed site for anastomosis whereby the severed end of the first hollow organ is matingly engaged with the sidewall of the

A method and instruments used to performing an end-to-end anastomosis between two portions of intestinal tissue is disclosed. The method involves drawing a first portion of intestinal tissue over a portion of a bioabsorbable stent. The end of the first portion of intestinal tissue is everted on the stent to create a collar of exposed inner intestinal tissue. A second portion of intestinal tissue is drawn over the stent and over the exposed intestinal tissue. A bandage containing one adhesive compound selected from the group of an adhesive and an adhesive initiator is wrapped about the juncture. The other adhesive compound is applied to saturate the bandage and the combination of an adhesive and an adhesive initiator sets the adhesive to adhere the first portion and the second portion of adhesive to the bandage.

Results: After exclusion of 10 noninformative pregnancies, perinatal, double, and any survival rates were 61%, 44%, and 77%, respectively. When an anastomosis was detected at each of the 3 time points, perinatal and double survival rates were higher than when one was not (at first treatment, perinatal survival 83% versus 53%, respectively, P = .003; double survival 78% versus 33%, P , .001). Perinatal and double survival (P ,= .01) were poorer with more advanced stage, but any survival rates were not influenced by stage or anastomosis detection. Multiple logistic regression demonstrated that anastomosis detection at treatment increased the chance of perinatal (odds ratio [OR] 5.1, 95% confidence interval [CI] 1.6, 15.9) and double survival (OR 19.3, 95% CI 2.7, 138), independently of stage. For stages I-III at treatment, anastomosis detection predicted better perinatal (100% versus 63%, 100% versus 59%, and 83% versus 44%, respectively) and double survival rates (100% versus 52%, 100% versus ...
Of 2609 relevant studies, 16 randomized controlled trials (RCTs) met our inclusion criteria. Nine RCTs (n=473) compared straight coloanal anastomosis (SCA) to the colonic J pouch (CJP). Up to 18 months postoperatively, the CJP was superior to SCA in most studies in bowel frequency, urgency, fecal incontinence and use of antidiarrheal medication. There were too few patients with long-term bowel function outcomes to determine if this advantage continued after 18 months postop. Four RCTs (n=215) compared the side-to-end anastomosis (STE) to the CJP. These studies showed no difference in bowel function outcomes between these two techniques. Similarly, three RCTs (n=158) compared transverse coloplasty (TC) to CJP. Similarly, there were no differences in bowel function outcomes in these small studies. Overall, there were no significant differences in postoperative complications with any of the anastomotic strategies. ...
When a vein segment is grafted into arterial circulation, biomechanical forces stimulate modification of its structure. This morphological adaptive response is progressive during a medium or long term and occludes the vessel lumen, leading to a graft failure. The objective of this study was to characterize the early morphological response of the vascular wall in a terminal-terminal vascular vein graft model in Wistar rats. A segment of the femoral vein was placed in the femoral circulation. An end to end microsurgical graft anastomosis technique was implemented and standardized in twenty rats. The samples were processed with histological technique to analyze the overall structure with hematoxylin and eosin, the composition of the vessel wall with Masson trichrome technique, the proliferating and smooth muscle cells were detected with immunohistochemistry (anti-PCNA, anti-actin and anti CD68) and the induction of apoptosis with TUNEL technique. The times periods studied were 1, 3 and 5 days ...

Logistic regression was used in both univariate and multivariate modelling.. The team used the methods to identify independent preoperative variables associated with the presence of intraoperative leak.. Model parameters were estimated by the maximum likelihood method. From these estimates, odds ratios with 95% confidence intervals were computed.. The investigators found no postoperative anastomotic leaks or mortalities in these series.. Overall, endoscopic evaluation of the gastrojejunostomy resulted in the detection of 16% of intraoperative leaks.. The team noted a difference in the incidence of intraoperative leakage for patients, with 21% older than 40 years, and 10% in those younger than 40 years. In the initial 91 cases, the gastrojejunostomy was performed by the end-to-end anastomosis technique.. The team reported that the subsequent 249 were performed with a combination of linear stapling and handsewn technique. There was a non-significant trend to less leakage in 12% with end-to-end ...
A ring for use in anastomosis. Preferably, the ring is integrally formed from metal, and includes a ring portion and tines and docking members that extend from the ring portion. The ring portion and tines are malleable, and preferably also the docking members are malleable. The ring portion and tines are malleable in the sense that once deformed from a first shape into a second shape, they will not relax back into the first shape from the second. To install the ring in a vessel with the ring portion extending around an incision or other orifice, the tines pierce the tissue around the orifice and are curled against an anvil. The action of curling the tines inverts the tissue near the orifice edges to expose the inside surface of the vessel or organ. Other aspects of the invention are a method and apparatus for installing an anastomosis ring in an incision or other orifice in a vessel or other organ, a method and apparatus for precisely aligning two anastomosis rings (each installed in an incision or

The anastomosis device according to the present invention is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes a frame for receiving and holding the end of a graft vessel in an everted position and first and second spreading members configured to be inserted into an opening in the target vessel. The first and second spreading members are arranged substantially in a plane for insertion into an opening in a target vessel, and are moved away from one another to capture the edges of the opening in the target vessel securing the graft vessel to the target vessel. One version of the anastomosis device includes a plurality of linkages arranged in two rows for grasping opposite sides of an opening in the target vessel. A portion of the linkages fold outward to trap vessel walls on opposite sides of the opening in the target vessel. The anastomosis devices greatly
Research conducted in our laboratory focuses on the fundamental aspects of fluid mechanics and mass transport that are involved in the modulation of mammalian cell function. Special attention is given to the cells in the arterial circulation and to the development of tissue-engineered vascular implants.. Our research activities include the development of instrumentation and methods for the accurate in vitro evaluation of cell function in variable mechanical environments. A main objective is to develop experimental models and theoretical analysis that will provide a good description of the dynamic process occurring in the arterial surface in early atherosclerosis. We are interested in the identification of physical mechanisms involved in cell pathobiology. In specific, we study cell communication, adhesion and injury in well controlled disturbed flow fields in vitro.. Three dimensional numerical simulations of the fluid flow in models of graft anastomosis and arterio-venous reconstructions are ...

Background: Fibrin-based biological adhesives are used for tissue adhesion improving the outcome of gastrointestinal sutures. The objective was to assess the effectiveness of fibrin-based biological adhesives for prevention of anastomotic leakage in high-risk gastrointestinal anastomoses. Methods: A randomized clinical trial was designed to recruit patients underwent a rectal resection surgery. A subgroup of patients with rectal anastomosis were recruited from 2 different hospital centres. Patients in which a biological fibrin-based biological adhesive was applied to the suture line (study group) were compared versus a control group under standard practice. The main outcome measures was presence or absence of leakage and need for reoperation. Results: Thirty seven patients underwent a rectal resection and anastomosis. In 21 standard practice was applied and a fibrin-based adhesive was used in 16. Fourteen patients (37.8%) had a clinical or subclinical anastomotic leak, 11 belonging to control group
