Abstrakt: Simple Summary: Minimally invasive approaches to total gastrectomy (TG) are gaining acceptance worldwide for the treatment of gastric cancer. Previous studies comparing short-term results were limited by pairwise comparisons and the inclusion of both total and distal gastrectomy. The present analysis aimed to compare the short-term outcomes of different techniques for TG comprehensively in the setting of GC. Lap-assisted TG (LATG), totally laparoscopic TG (TLTG), and robotic TG (RTG) seem to be associated with a lower overall complications rate and improved short-term functional outcomes compared to open TG (OTG). Severe postoperative complications and anastomotic leak seem comparable across techniques. Our findings support the adoption of minimally invasive TG techniques in the surgical management of gastric cancer. Background/Objectives: Total gastrectomy (TG) is the cornerstone treatment for gastric cancer (GC). While open TG (OTG) with D2 lymphadenectomy remains the gold standard, alternative techniques such as lap-assisted TG (LATG), totally laparoscopic TG (TLTG), and robotic TG (RTG) have been reported with promising outcomes. The present analysis aimed to compare the short-term outcomes of different techniques for TG comprehensively in the setting of GC. Methods: A systematic review and network meta-analysis were performed. The primary outcomes were overall complications (OC), severe postoperative complications (SPCs), and anastomotic leak (AL). Pooled effect-size measures included risk ratio (RR), weighted mean difference (WMD), and 95% credible intervals (CrIs). Results: Sixty-eight studies (44,689 patients) were included. Overall, 52.4% underwent OTG, 6.5% LATG, 39.2% TLTG, and 1.9% RTG. Both TLTG (RR 0.82; 95% CrI 0.73–0.92) and RTG (RR 0.75; 95% CrI 0.59–0.95) showed a reduced rate of postoperative OC compared to OTG. SPCs and AL RR were comparable across all techniques. Despite the longer operative time, LATG, TLTG, and RTG showed reduced intraoperative blood loss, time to first flatus, ambulation, liquid diet resumption, and hospital stay compared to OTG. Conclusions: Minimally invasive approaches seem to be associated with improved OC and functional outcomes compared to OTG. [ABSTRACT FROM AUTHOR]
