Comparison of totally laparoscopic total gastrectomy and laparoscopic-assisted total gastrectomy: A systematic review...

Laparoscopic-assisted total gastrectomy (LATG) has been extensively employed for the removal of gastric tumors, although it has several limitations. Totally laparoscopic total gastrectomy (TLTG) is a new technique that has rapidly been gaining popularity, and may help overcome the limitations of LATG; however, its safety and therapeutic effect remain controversial. In the present study, we aimed to assess the safety and efficacy of TLTG, and compare the short-term outcomes of TLTG and LATG.

We searched for studies comparing TLTG and LATG published up to April 2018 from databases such as PubMed and Embase. The study results, including time of surgery, blood loss, anastomosis time, retrieved lymphatic nodes, proximal and distal resection edges, incision length, time to first fluid and soft diet, hospitalization duration, time to first flatus, and postsurgical and anastomotic complications, were compared between the procedures.

A total of 10 studies were included. TLTG led to reduced intraoperative blood loss (P < 0.01), greater number of retrieved lymphatic nodes (P < 0.01), decreased hospitalization duration (P < 0.01), reduced incision length (P = 0.05), and shorter time to first fluid diet (P < 0.05), as compared to LATG. The surgery and anastomosis times, time to first soft diet, resection edge, time to first flatus, overall postsurgical complications, and anastomosis-related complications were similar between TLTG and LATG (P > 0.05).

TLTG is a safe procedure that yields better cosmesis lower invasiveness, and faster recovery as compared to LATG.
