术中置胃胆管、胆总管一期缝合在胆总管探查术中的应用

目的建立胆总管探查术后胃胆管引流、胆总管一期缝合的动物模型(简称胃胆管引流术),探讨胃胆管引流术的可行性和临床价值.方法将30只犬随机分为3组:对照组(仅行腹腔探查,n=5),胆总管一期缝合组(简称一期缝合组,n=10),胃胆管引流、胆总管一期缝合组(简称胃胆管组,n=15).观察术后肝功能的变化、胆漏等并发症,评估胃胆管引流术的安全性.结果对照组术后无一血清总胆红素(TBil)升高.一期缝合组术后3只犬血清TBil显著升高,4只犬血清TBil轻度升高;胃胆管组术后无一血清TBil显著升高,后两者差异有统计学意义(P＜0.01).胃胆管组平均拔管时间(7.0±1.7)d,无一发生胆漏、腹腔感染及切口感染、裂开;一期缝合组术后5只犬胆漏,其中3只犬发生胆汁性腹膜炎,两者差异有统计学意义(P＜0.05).结论胃胆管引流术安全可行,胆道引流时间短、避免了胆总管一期缝合术后胆漏等并发症,具有其独特的临床应用价值.

The experimental study on application of gastrobiliary duct drainage in primary suture after exploration of common bile duct

Objective To establish an animal model with installation of gastrobiliary duct drainage (GBDD) in the primary suture after exploration of common bile duct, to assess the safety and feasibility of GBDD. Methods Thirty dogs were randomly divided into three groups: control group (n=5), primary suture group (n= 10) and GBDD group (n= 15). Serum TBil levels, bile leakage,and complications were observed and compared. Results No increase in serum TBil level was observed in the control group. However, serum TBil levels were significantly increased in the primary suture group compared to the GBDD group (P＜0. 01). GBDD were all successfully withdrawn at mean (7. 0±1.7) days after the operation. No bile leakage was found in the GBDD group, which was significantly different compared to 5/10 bile leakage cases in primary suture group (P＜0. 05). There were 3/10 cases of bile peritonitis, infection of incisional wound and splitted in the primary suture group, while there were no such complications in the GBDD group (all P＞0.05). Conclusions GBDD is safe and feasible. It can shorten biliary drainage time and prevent occurrence of bile leakage.Therefore, it has unique value in clinical application.
