Abstract

Background

To decrease the incidence of internal hernia after laparoscopic Roux-en-Y gastric bypass, recent recommendations indicated closure of mesenteric defects and Petersen’s defect. Laparoscopic distal gastrectomy for gastric cancer is used increasingly, so the incidence of Petersen’s hernia can also increase, but the trend has not been studied.

Methods

This study retrospectively reviewed 358 consecutive patients who underwent laparoscopic distal gastrectomy for gastric cancer at one institution, with antecolic Roux-en-Y (RY) reconstruction.

Results

Petersen’s hernia occurred in 6 (2.2 %) of 268 patients whose Petersen’s defect was not closed by a mean of 351 days after surgery. All the patients underwent reoperation with reduction and repair of the hernia except the first case. In 90 subsequent cases, with closure of the Petersen’s defect, internal hernias did not occur (0/90 cases; p = 0.06). Focusing on the totally laparoscopic procedure, Petersen’s hernia occurred in 2 (5.1 %) of 39 patients, whereas in 81 subsequent cases, with closure of Petersen’s defect, internal hernias did not occur (0/81 cases; p = 0.03).

Conclusions

Based on the recent recommendations for bariatric surgery, closure of this potential hernia defect is necessary after laparoscopic distal gastrectomy with R-Y reconstruction for gastric cancer.
