Effect of endoscopic resection on short-term surgical outcomes of subsequent laparoscopic gastrectomy: a meta-analysis

Abstract

Background: Endoscopic resection (ER) might affect subsequent laparoscopic gastrectomy (LG) because of the electrical coagulation, but the effect remains controversial. The purpose of this meta-analysis was to analyze the effect of ER on the short-term surgical outcomes of subsequent LG.

Materials and methods: The PubMed, EMBASE, and Cochrane Library databases were searched to find eligible studies published from inception to March 21, 2021. Short-term surgical outcomes were compared between the ER-LG group and the LG-only group. The registration ID of this current meta-analysis on PROSPERO is CRD42021238031.

Results: Nine studies involving 3611 patients were included in this meta-analysis. The LG-only group had a higher T stage (T1-T2: OR=2.42, 95% CI=1.09 to 5.34, P=0.03; T3-T4: OR=0.41, 95% CI=0.19 to 0.91, P=0.03) than the ER-LG group. The ER-LG group showed a shorter operation time than the LG-only group (MD=-5.98, 95% CI=-10.99 to -0.97, P=0.02). However, no difference was found in operation time after subgroup analysis of propensity score matching studies. No significant difference was found in intraoperative blood loss, time to first oral feeding, or postoperative hospital stay between the ER-LG group and the LG-only group. And no significance was found in overall complications (OR=1.16, 95% CI=0.89 to 1.50, P=0.27), complications of grade ≥ II (OR=1.11, 95% CI=0.71 to 1.73, P=0.64), complications of grade ≥ III b (OR=1.47, 95% CI=0.49 to 4.43, P=0.49) between the ER-LG group and the LG-only group.

Conclusions: ER did not affect subsequent LG in terms of short-term outcomes, and the ER-LG group might have a shorter operation time than the LG-only group.
