The aim of this study was to evaluate the feasibility of a totally stapled gastrojejunal anastomosis performed using one transabdominal 12-mm trocar and a gastroscope in a porcine model.
The procedure was carried out on six domestic pigs weighing 45 kg using a hybrid technique with a gastroscope and a 12-mm Hasson trocar, positioned in the left hypochondrium. At the end of the procedure a mechanical circular 21-mm gastrojejunal anastomosis was performed by inserting the stapler through a small gastrotomy after enlarging the trocar incision.
In all six cases the procedure was completed through a single 3 cm abdominal incision and without complications. The mean operating time was 2 h, and endoscopic investigation showed that the anastomoses were intact, patent, and airtight.
Totally stapled gastrojejunal anastomosis using a hybrid NOTES-single 12-mm trocar approach is a feasible procedure in the porcine model. Further survival studies are warranted, particularly to evaluate the functional results of this procedure.
本研究旨在评估在猪模型中使用一个经腹腔 12mm 套管和胃镜进行全吻合钉胃空肠吻合术的可行性。
该程序在 6 头重 45 公斤的家猪上使用混合技术进行，使用胃镜和位于左季肋部的 12mm Hasson 套管。在手术结束时，通过扩大套管切口，将吻合器插入小胃造口来完成机械圆形 21mm 胃空肠吻合。
在所有 6 例中，手术均通过单一 3cm 的腹部切口完成，且无并发症。平均手术时间为 2 小时，内镜检查显示吻合口完整、通畅且无泄漏。
在猪模型中，使用混合NOTES-单一 12mm 套管方法进行全吻合钉胃空肠吻合术是可行的。需要进一步进行生存研究，特别是评估该手术的功能结果。
