To compare the clinical outcome of total laparoscopic modified triangle anastomosis and laparoscopic-assisted BillrothⅠanastomosis for digestive tract reconstruction after radical gastrectomy.

From February 2014 to April 2017, 70 patients with distal gastric cancer were enrolled and randomly divided into group A (35 cases) and group B (35 cases). All patients underwent distal gastrectomy combined with D2 lymphadenectomy, patients in group A received total laparoscopic modified triangular anastomosis, while patients in group B received laparoscopic-assisted BillrothⅠanastomosis. Statistical analysis were performed by using SPSS19.0 software. Intraoperative and postoperative clinical indicators were presented as mean±standard deviation, and were examined by using t test. The postoperative complication rate were expressed as %, and were compared with χ² test. P<0.05 was thought to be statistically significant.

The operation time and intraoperative blood loss in group A were lower than those in group B, meanwhile the harvested lymph nodes in group A was more than that in group B, and exhaust time, first inflow time, hospital stay in group A were shorter than those in group B, with significant difference (P<0.05). The total incidence of postoperative complications was 11.4% in group A and 17.1% in group B, with no significant difference (P>0.05). There were no anastomotic stenosis, tumor recurrence and death during follow-up period.

Compared with laparoscopic-assisted BillrothⅠanastomosis, the total laparoscopic modified triangular anastomosis has more minimally invasive advantages, including shorter operation time, less blood volume, better oncological outcome, faster postoperative recovery, which is worthy of clinical promotion.
