背景技术背景：传统的胆肠Roux-en-Y吻合术技术复杂，术后并发症发生率高。方法：将16只犬随机分为两组，每组8只，结扎胆总管7 d后，取胆总管空肠，用自制的磁性压迫器行胆总管空肠吻合术。研究组采用吻合口，对照组采用传统的手工缝合方法进行标准Roux-en-Y胆肠吻合。比较两组患者术后1个月和3个月的手术时间、并发症发生率、大体外观和吻合口病理差异。两组均未发生吻合口狭窄，但对照组胆肠吻合口狭窄率明显高于对照组。对照组有1例胆漏，而研究组无胆漏发生。一个更光滑的表面，一个改进的层贴壁，和较低的局部炎症反应被确定在吻合的studygroup.CONCLUSION：新型磁压缩支架的结构简单，他们是省时，安全和有效的执行Roux-en-Y胆肠吻合术程序在犬梗阻性黄疸模型。（肝胆胰疾病国际2012;11：81-88）
BACKGROUND: The traditional hand-sewn Roux-en-Y choledochojejunostomy is technically complicated, and the incidence of postoperative complications has remained high. A set of novel magnetic compressive anastomats was introduced to facilitate choledochojejunostomy and improve the prognosis of patients.METHODS : After ligating the common bile duct for 7 days, 16 dogs were randomly divided into two groups (n=8 per group). Anastomats were used in the study group, and the traditional hand-sewn method was used in the control group for standard Roux-en-Y choledochojejunostomy. We compared the operation time, incidence of complications, gross appearance, and pathological disparity in stoma between the two groups in 1-month and 3-month follow-tip examinations.RESULTS: The time spent on constructing the anastomosis for the study group was significantly shortened. Although no anastomotic stenosis occurred in the two groups, the narrowing rate of biliary-enteric anastomosis was much higher in the control group. There was one case of bile leakage in the control group, whereas no bile leakage occurred in the study group. A smoother surface, an improved layer apposition, and a lower local inflammatory response were identified in the anastomosis of the study group.CONCLUSION: The structures of the novel magnetic compressive anastomats are simple, and they are time-saving, safe and efficient for performing Roux-en-Y choledochojejunostomy procedures in a canine model of obstructive jaundice.
