To investigate the short-term effect of distal radical gastrectomy for Borrmann typeⅢ-Ⅳgastric cancer using single incision plus one port laparoscopic surgery (SILS+1).

Eighty-one patients with laparoscopic distal radical gastrectomy admitted to Langfang Municipal People’s Hospital from January 2018 to December 2020 were prospectively selected, all of whom were Borrmann typeⅢ-Ⅳ. According to digital random method, they were divided into SILS+1 group (41 cases) and traditional 5-hole laparoscopic group (5-hole group, 40 cases). All patients received perioperative accelerated rehabilitation surgical concept support. The changes of perioperative related indexes, postoperative complication rate, nutritional status indexes and inflammatory stress indexes were compared between the two groups.

The incision length, bowel sound recovery time and postoperative hospitalization time of SILS+1 group were better than those of the 5-hole group (all P<0.05). There were no significant differences in operative time, intraoperative blood loss, the number of dissected lymph nodes, and the total incidence of postoperative complications between the two groups. On 1 and 5 days after operation, the recovery of serum albumin, prealbumin, C-reactive protein and interleukin-6 levels in SILS+1 group were better than those in 5-hole group (P<0.05).

The application of SILS+1 laparoscopic radical distal gastrectomy for Borrmann type Ⅲ-Ⅳgastric cancer can effectively improve the postoperative nutritional status, reduce inflammatory response, and promote postoperative recovery, with good short-term efficacy.
