Abstract

Background: Performing an intestinal anastomosis is a challenging part of laparoscopic surgery, and ensuring adequate closure is essential to prevent anastomotic leakage. The aim of this study was to develop an objective method for quantitative assessment of laparoscopic intestinal anastomosis during simulation training.

Methods: A modular intraluminal air leakage device, the LeakChecker, was designed and validated by comparing laparoscopic intestinal anastomoses performed by laparoscopic novices and experts. The MaxForce, MeanNon-zero force, PathLength and DepthPerception parameters from the Lapron box-trainer vs MaxPressure and PressureArea from the LeakChecker were used for comparison.

Results: A functional prototype was built and the data of 10 laparoscopic novices and seven experts were included. Anastomoses made by the experts tolerated a higher MaxPressure (3,10(2,51-7,24)kPa vs 0,98(0,81-1,35)kPa; p=0.010) and showed a higher pressureArea (24,89(16,13-100,04)kPa*t vs 5,99(4,78-9,23)kPa*t; p=0.032). The Lapron box trainer data showed significant differences between the experts and novices for almost all including force and motion parameters.

Conclusion: The LeakChecker can quantify anastomotic leakage during training as it objectively distinguishes between novices and experts. Implementing this kind of smart training task in a training program with objective skill assessment would inform participants of both their instrument handing skills and the quality of their execution.

LeakChecker：腹腔镜肠吻合训练中漏气定量评估。

背景：进行肠道吻合是腹腔镜手术的一个具有挑战性的部分，确保足够的闭合是防止吻合口漏的必要条件。本研究的目的是在模拟训练中建立一种客观的方法来定量评估腹腔镜肠吻合术。方法：设计一种组合式腔内漏气装置LeakChecker，并通过比较腹腔镜新手和专家的腹腔镜肠吻合术进行验证。使用Lapron box-trainer的MaxForce、menon -zero force、PathLength和DepthPerception参数与LeakChecker的MaxPressure和PressureArea进行比较。结果：构建了功能原型，纳入了10名腹腔镜新手和7名专家的数据。专家制作的吻合器承受更高的最大压力(3,10(2,51-7,24)kPa vs 0,98(0,81-1,35)kPa；p=0.010)，显示出更高的压力面积(24.89 (16,13-100,04)kPa*t vs 5.99 (4,78-9,23)kPa*t；p = 0.032)。拉普龙箱子训练器数据显示，专家和新手在包括力和运动参数在内的几乎所有方面都存在显著差异。结论：LeakChecker能够在训练过程中对吻合口漏进行量化，客观区分新手和专家。在一个有客观技能评估的培训项目中实施这种智能训练任务，将告知参与者他们的仪器处理技能和执行质量。

期刊介绍： Minimally Invasive Therapy and Allied Technologies (MITAT) is an international forum for endoscopic surgeons, interventional radiologists and industrial instrument manufacturers. It is the official journal of the Society for Medical Innovation and Technology (SMIT) whose membership includes representatives from a broad spectrum of medical specialities, instrument manufacturing and research. The journal brings the latest developments and innovations in minimally invasive therapy to its readers. What makes Minimally Invasive Therapy and Allied Technologies unique is that we publish one or two special issues each year, which are devoted to a specific theme. Key topics covered by the journal include: interventional radiology, endoscopic surgery, imaging technology, manipulators and robotics for surgery and education and training for MIS.
