Kissing式胰肠吻合的动物实验研究

Animal experimental study on Kissing pancreaticojejunostomy

目的 通过动物实验探索Kissing式胰肠吻合的可行性和安全性,明确胰管、黏膜愈合的病理过程.方法 通过测定胰肠吻合后吻合口耐受压,求证该吻合的严密性；通过吻合后不同时间的手术探查、胰肠管造影和病理学检查证实吻合后胰腺残端与空肠黏膜之间愈合情况和病理演变过程.结果 所有实验犬均顺利完成胰肠吻合术,耐受压测定均在90 cm H2O以上,各时间段处死的实验犬均见吻合口紧密,无出血、瘘口,造影见胰管与肠腔连续,充盈良好,未见造影剂外渗现象.病理切片提示4周后胰管与空肠黏膜间形成瘢痕愈合,连接紧密.结论 Kissing胰肠吻合简便,易推广,胰管、空肠黏膜间可形成严密瘢痕愈合,未见积液或脓腔等,具有临床应用价值.

Objective To evaluate the feasibility and safety of the modified panceaticojejunostomy called Kissing panceaticojejunostomy by animal experiment,and to explore the pathological process of primary healing between the pancreatic duct and the jejunal mucous.Methods The tolerance pressure at the anastomotic intestine was measured during surgery to ensure close contact suture of Kissing panceaticojejunostomy.Exploratory laparotomy,pancreatic ductography and pathology was performed at 2,4 weeks after panceaticojejunostomy.Results Kissing panceaticojejunostomy was performed successfully on 6 Beagle dogs.Tolerance pressure in all dogs was 90 cm H2O and above.No bleeding、fistula or contrast extravasation was found,and healing anastomosis was identified by laparotomy and pancreatic ductography.Cicatricial healing was found between pancreatic duct and jejunal mucosa 4 weeks after anastomosis.Conclusions Kissing panceaticojejunostomy is easy to perform,ensuring close-up cicatricial healing without hydrops or abscess between pancreatic duct and jejunal mucosa.
