To compare the safety and short-term efficacy of complete endoscopic Billroth Ⅱ anastomosis and small incision manual Billroth Ⅱanastomosis in laparoscopic distal gastrectomy.

From January 2015 to December 2020, the medical records of 277 patients who underwent laparoscopic distal gastrectomy in Zhongshan City People’ s Hospital were retrospectively analyzed. In the trial group of 114 cases, the posterior wall of the remnant stomach was completely anastomosed with the jejunum by using the linear cutting occluder. In the control group of 163 cases, a small incision was made in the upper abdomen, and the remnant stomach and jejunum were manually anastomosed outside the abdominal cavity. The intraoperative conditions, postoperative complications and early postoperative recovery of the two groups were compared.

The operation time and anastomosis time, and the incision length of the trial group was shorter than that of the control group, while the postoperative pain score of the trail group was lower than that of the control group, the postoperative exhaust time was earlier than that of the control group, and the postoperative hospital stay was less than that of the control group, and the differences were statistically significant (P<0.05). There were no significant differences in intraoperative blood loss and incidence of postoperative complications between the two groups.

It is safe and feasible to use the linear cutting closure device to complete laparoscopic Billroth Ⅱ anastomosis in laparoscopic distal gastrectomy, which is worthy of promotion.
