A Modified Purse-String Stapling Technique for Intracorporeal Circular Stapled Esophagojejunostomy During Laparoscopic Total Gastrectomy: Comparison with Extracorporeal Reconstruction Technique.

Background

Intracorporeal esophagojejunostomy (EJ) in the context of laparoscopic total gastrectomy remains a complex and technically demanding procedure. We have previously introduced a novel method of intracorporeal circular stapled EJ utilizing a conventional purse-string suture instrument. Since May 2018, we have refined this technique, and the aim of this study was to assess its safety and efficacy.

Methods

Between May 2018 and June 2022, we enrolled 92 patients who underwent laparoscopic total gastrectomy with the modified intracorporeal reconstruction method. In addition, between March 2014 and June 2022, we enrolled 121 patients who underwent the procedure with the extracorporeal reconstruction method. We retrospectively collected and compared the clinical data of these 2 patient cohorts.

Results

Intracorporeal reconstruction group experienced lower postoperative pain scores (2.7 ± 1.3 versus 4.5 ± 1.4, P = .032), reduced administration of analgesics (3.1 ± 2.2 versus 5.0 ± 3.5, P = .041), and shorter postoperative hospital stays (4.9 ± 2.3 versus 6.3 ± 3.5, P = .045) compared with the extracorporeal reconstruction group. In addition, anastomotic time and postoperative pain score were not increased in the overweight patients in the intracorporeal reconstruction group. Anastomotic leakage occurred in 2 (2.2%) patients in the intracorporeal reconstruction group and 4 (3.3%) patients in the extracorporeal reconstruction group. Anastomotic stricture occurred in 1 (1.1% and 0.8%) patient in each group. There was no significant difference in the overall postoperative complication rate between the 2 groups.

Conclusions

The modified intracorporeal purse-string stapling technique for EJ during laparoscopic total gastrectomy is a safe and viable option, exhibiting less invasiveness and comparable outcomes to the extracorporeal reconstruction method, especially suitable for obese patients.
