摘要比较传统Billroth-Ⅰ吻合与Overlap吻合方式腹腔镜辅助胃癌切除术后的消化道重建中的应用效果。研究发现Overlap吻合组消化道吻合时间、手术时间、首次排气时间及住院时间短于传统吻合组，腹部切口长度短于传统吻合组（ P<0.05）。提示腹腔镜辅助远端胃切除术将Overlap吻合应用于Billroth-Ⅰ消化道重建中可有效缩短患者术后吻合时间，推荐应用。

abstractsThe purpose of this study was to compare the usefulness of classical Billroth-I anastomosis vs overlap anastomosis in gastrointestinal reconstruction after laparoscopy-assisted resection of gastric cancer. The study demonstrated shorter time for gastrointestinal anastomosis, shorter operation time, time to flatus, length of hospital stay, and shorter abdominal incision with overlap anastomosis compared with the classical Billroth-I anastomosis ( P<0.05) . These findings suggests that overlap anastomosis used for Billroth-I gastrointestinal reconstruction can effectively shorten the anastomosis time after laparoscopic distal gastrectomy, and is recommendable for clinical use.
