Feasibility of a Novel Laparoscopic Technique with Unidirectional Knotless Barbed Sutures for the Primary Closure of Duodenal Ulcer Perforation.

Laparoscopic primary repair is one of the main procedures used for perforated gastric ulcers, and this technique requires reproducible and secure suturing. The aim of this study was to investigate the safety and efficacy of a novel continuous suture method with barbed sutures during laparoscopic repair for perforated peptic ulcers.
