Assessment of a manipulator device for NOTES with basic surgical skill tests: a bench study.
Advanced complex surgery performed with the natural orifice translumenal endoscopic surgery technique requires use of a multitasking platform. The aim of this study is to evaluate the basic functionality of a prototype multitasking platform "EndoSAMURAI" with the use of a biosimulation model and ex vivo porcine stomach. We compared the performance of basic surgical skill tasks between the EndoSAMURAI and standard laparoscopic instrumentation. Basic surgical tasks include cutting, dissection, and suturing and knot tying. Main outcome measurements were the time to complete each task and leak pressure to evaluate the quality of the suturing and knot tying. Although it took longer to perform all basic surgical tasks with the EndoSAMURAI than with laparoscopic instrumentation, all tasks could be performed precisely and with an accuracy comparable to that of the laparoscopic technique. Leak pressures of the gastric closure site between both techniques were also comparable.
