The application of OTSC clamping system to perforation closure of gastrointestinal tract(with video)

Abstract

Objective To investigate the application and therapeutic effects of OTSC clamping system on perforation closure of gastrointestinal tract. Methods A total of 21 cases of gastrointestinal perforation or digestive tract fistula patients underwent OTSC closure.The perforation tissue was drawn into the transparent cap with grasping forceps, and then the rake holder was released. Results OTSC was successfully performed in 1case of tracheoesophageal fistula, 1 case of esophageal perforation, 12 cases of gastric perforation, 2 cases of duodenal perforation, 1 case of ileocecal valve perforation, 1 case of colon perforation, 3 cases of rectum perforation. Nineteen cases of perforation were iatrogenic and 2 chronic perforation. The diameter of perforation was 0.3-4.0 cm, with mean diameter being(1.6±0.8) cm. No intraoperative hemorrhage, delayed bleeding or deaths occurred. Conclusion OTSC clamping system is safe, effective new technology and worth clinical recommendation to gastrointestinal perforation or fistula.
