A Study of a Novel Disposable Endoscopic Purse-String Suture Auxiliary Instrument for the Treatment of Full-Thickness Gastric Wall Defects.

ABSTRACT:

Objectives

In this study, we aimed to evaluate the effectiveness of a novel endoscopic purse-string suture auxiliary instrument compared with traditional methods for closure of a full-thickness defect of the stomach in an ex vivo model.

Methods

Twelve perforation sites (10-20 mm in diameter) were created in the ex vivo porcine stomach models. Two physicians (A and B had performed endoscopic surgery for 6 and 3 years) performed suturing using both the experimental and traditional (control) instruments. Operation time, success rate, and number of attempts for successful suture required were recorded.

Results

For physician A, the median suturing time was 56.50 s (interquartile range [IQR] 40.50 s, 134.50 s) and 215.50 s (IQR 63.75 s, 254.75 s) in the experimental and con
