背景:通过柔性内窥镜进行的自然腔道内镜手术(NOTES)胆囊保留手术是一种新兴技术。然而,胆囊在手术过程中未能获得牵引和定位功能。
目的:为了评估一种新的手术方法的可行性和安全性,“圈套器辅助纯注释胆囊保留手术”。
方法:将8只小型猪随机分为实验组[NOTES使用圈套器进行保胆手术,圈套辅助(SA)]和对照组(NOTES不使用圈套器的胆囊保留手术,NC),每组4例。两组动物在手术时间上的差异,操作工作量,并发症,不良事件,白细胞,和肝功能测定。
结果:手术成功率没有差异,胆囊切口闭合,白细胞计数,或肝功能在两组之间。总运行时间,胆囊切口失血,胆囊迷失方向的时间,胆囊切口闭合时间,SA组的国家航空航天局-任务负荷指数的工作量得分明显降低(P<0.05)。
结论:这些结果表明,使用标准内窥镜器械的圈套器辅助单纯的NOTES胆囊保存手术降低了手术难度,缩短操作时间,并且没有增加猪的并发症。提供了一种纯NOTES保胆手术的新方法。
BACKGROUND: Natural orifice transluminal endoscopic surgery (NOTES) gallbladder-preserving surgery by flexible endoscopy is an emerging technology. However, the gallbladder fails to obtain traction and positioning functions during the operation.
OBJECTIVE: To evaluate the feasibility and safety of a new surgical method, \"
snare-assisted pure NOTES gallbladder-preserving surgery\".
METHODS: Eight miniature pigs were randomly divided into the experimental group [NOTES gallbladder-preserving surgery using the
snare device,
snare assisted (SA)] and the control group (NOTES gallbladder-preserving surgery without using the
snare device, NC), with four cases in each group. The differences between the two groups of animals in operating time, operating workload, complications, adverse events, white blood cells, and liver function were determined.
RESULTS: No differences were found in the surgical success rate, gallbladder incision closure, white blood cell count, or liver function between the two groups. The total operating time, gallbladder incision blood loss, gallbladder disorientation time, gallbladder incision closure time, and workload scores on the National Aeronautics and Space Administration-Task Load Index were significantly reduced in the SA group (P < 0.05).
CONCLUSIONS: These results indicated that
snare-assisted pure NOTES gallbladder-preservation surgery using standard endoscopic instruments reduced the difficulty of operation, shortened operation time, and did not increase complications in pigs. A new method for pure NOTES gallbladder-preservation surgery was provided.
