Totally laparoscopic total gastrectomy using the "enjoyable space" approach coupled with self-pulling and latter transection reconstruction versus laparoscopic-assisted total gastrectomy for upper gastric cancer: short-term outcomes.

With the development of minimally invasive surgery in recent years, totally laparoscopic total gastrectomy (TLTG) has attracted more attention.

To introduce the more comprehensive "enjoyable space" approach coupled with the self-pulling and latter transaction (SPLT) reconstruction technique to perform TLTG and investigate its safety and feasibility.

Ninety-seven patients with primary upper gastric cancer underwent laparoscopic radical total gastrectomy between January 2020 and December 2020. Among these patients, 46 underwent laparoscopic-assisted total gastrectomy (LATG), and 51 underwent TLTG. We compared the clinicopathological characteristics, surgical outcomes and postoperative complications between the two groups.

There were no significant differences in the clinicopathological characteristics between the two groups (p > 0.05). However, the TLTG group had a slightly lower mean operative time and mean blood loss than the LATG group (p < 0.05 each). Although there were similarities in the mean times to first flatus, liquid diet, and soft diet, the duration of hospital stay was significantly reduced in the TLTG group (p < 0.05). No significant differences in overall complications and E-J-related complications were found between the two groups (15.2% vs. 25.4%, p > 0.05).

TLTG is a safe and feasible procedure for treating upper gastric cancer. The enjoyable space approach in conjunction with SPLT reconstruction is an appropriate comprehensive technique with several advantages over LATG.
