Abstract

BACKGROUND AND AIM:

Current endoscopic full-thickness resection (EFTR) methods are limited by their transmural communication and exposure of tumor to the peritoneum. The aim of this study was to test the feasibility of a new resection technique that does not expose the mucosa to the peritoneum, although it involves an easy and secure suture method, which could be applied in the clinical setting.

METHODS:

The nonexposure endolaparoscopic full-thickness resection with simple suturing technique was performed in four pigs. This new technique includes the steps of laparoscopic seromuscular suturing, which results in inversion of the stomach wall; EFTR of the inverted stomach wall from inside the stomach; and finally, endoscopic mucosal suturing with endoloops and clips.

RESULTS:

En bloc and complete resections were achieved without adverse events in all pigs. The mean (± standard deviation) operation time was 137.0 ± 28.2 minutes. All pigs survived with no clinical evidence of illness until euthanasia. Gross and microscopic examination of the resection site showed healing without evidence of leakage or infection.

CONCLUSION:

The nonexposure endolaparoscopic full-thickness resection with simple suturing technique was feasible in an animal model.
