腹腔镜全胃切除术进行辅助小切口下的消化道重建有时较为困难。一些应用机械吻合为主的体内食管空肠吻合技术被开创应用，其中线性吻合器overlap法因易于操作且吻合口宽目前最受青睐。近期报道的基于倒刺线改良的overlap法引起我们的关注，现已作为我中心全腔镜全胃切除术的主要技术。

For laparoscopic total gastrectomy, there is concern about the dificulty of extracorporeal gastrointestinal reconstruction through a mini abdominal incision. Several kinds of techniques using mechanical staplers have been reported to complete an intracorporeal esophagojejunostomy. Among them, the overlap method by using an linear stapler is favored because it facilitates handling of the stapler with a wider anastomosis stoma. Recently a new modified overlap method using knotless barbed sutures were reported. Now it has been a primary technology for totally laparoscopic total gastrectomy at our center.
