ABSTRACT
Objective To evaluate the efifcacy of endoscopic Over-The-Scope-Clip system (OTSC) system for the acute iatrogenic digestive tract perforation. Methods To collect 11 cases with digestive tract perforation closed with the OTSC system, including 7cases of gastric perforation, 1 case of duodenal perforation,3 cases of colorectal perforation. Results 11 cases were successfully closed with OTSC system in time, the average time needed for the endoscopic closure is 6~15 min. And the perforation diameter is 0.6~3.7 cm, average diameter is (1.89 ± 0.27) cm. No intraoperative bleeding and delayed hemorrhages, no deaths occurred. Conclusion Endoscopic OTSC system is a successful method for the digestive tract perforation and is worth to popularize.
ABSTRACT
Objective To evaluate the clinical efficacy of the over-the-scope-clip (OTSC) for endoscopic closure of acute refractory non-variceal upper gastrointestinal bleeding. Methods This retrospective study selected 16 refractory patients, including 2 cases with Mallory-Weiss syndrome, 7 cases with gastric ulcer, 1 case with gastric carcinoma and 6 cases with duodenal ulcer, underwent OTSC treatment of acute non-variceal upper gastrointestinal bleeding from January 2015 to June 2016 as study subjects. Results All of the 16 patients with bleeding lesions were successfully controlled. The successful rate is 100.0%. The mean procedure of OTSC for endoscopic bleeding closure was between 5.0 and 6.0 min. Conclusion The Over-the-Scope-Clip system is safe and effective for closure of acute non-variceal upper gastrointestinal bleeding in refractory patients, and deserves further clinical applications.
