Core Tip
Core tip: The feasibility and safety of the laparoscopic approach in overweight (OW) patients and cases of total gastrectomy were already reported, but an assessment of the feasibility and safety of laparoscopic total gastrectomy (LTG) in OW patients has not yet been conducted. In the article we performed two main analyses. One is a comparison of postoperative outcomes after LTG between OW and non-OW patients. The other is that after open total gastrectomy. In order to balance the baseline characteristics between laparoscopy and open groups, we performed propensity score matching. We found out two main results through the analyses. One is LTG in OW patients is feasible and safe although it remains technically challenging (longer operation time). The other is OW has less impact on laparoscopic versus open approach.
