Single-incision plus one-port laparoscopic gastrectomy versus conventional multi-port laparoscopy-assisted gastrectomy for gastric cancer: a retrospective study

Abstract

We compared short-term perioperative outcomes after single-incision plus one-port laparoscopic gastrectomy (SILG+1) and conventional multi-port laparoscopy-assisted gastrectomy (C-LAG) for gastric cancer. The work was conducted between August 2017 and October 2019. A total of 90 patients with early or advanced gastric cancer were retrospectively analyzed: 43 patients of which underwent SILG+1, and 47 of which underwent C-LAG, respectively. These were divided into two groups: the total gastrectomy group (SILT+1 and C-LATG) and the distal gastrectomy group (SILD\u2009+\u20091 and C-LADG). The demographics, tumor characteristics, postoperative outcomes, and short-term complications of all enrolled patients were summarized and statistically analyzed. The mean incision length in SILT+1 group was 5.40 cm shorter than that in C-LATG group (3.15\u2009±\u20090.43 vs. 8.55\u2009±\u20092.72, P\u2009<\u20090.001). This comparison between the SILD\u2009+\u20091 and the C-LADG group produced comparable results. The SILT+1 group underwent a 56.32 min longer operation than the C-LATG group (273.03\u2009±\u200966.80 vs. 216.71\u2009±\u200982.61, P\u2009=\u20090.0205). SILG+1 group had better postoperative visual analog scale (VAS) and cosmetic score than those of the C-LATG group (P\u2009<\u20090.05). There were no significant differences in preoperative demographics or 30-day postoperative complication rates between the SILG+1 and C-LAG groups. Tumor-related index, including mass size, histological type, number of retrieved lymph nodes, pathological tumor-node-metastasis (TNM) stage, and proximal and distal edges were all equivalent between the SILG+1 and the C-LAG group. This retrospective study demonstrates the safety and feasibility of SILG+1 with D1+\u2009or D2 lymphadenectomy for the treatment of early and advanced gastric cancers, compared with C-LAG.
