Korean multicenter study confirms efficacy and safety of OTSC® for GI fistulas, leaks and perforations

All 19 patients were treated successfully with the OTSC System. In 74 % of cases, complete healing of the leakage was achieved using OTSC alone

Lee HK et al., Department of Internal Medicine, Hanyang University College of Medicine, Seoul, Korea, performed a prospective multicentre multicenter study at seven centers in Korea aiming to examine the therapeutic success rate of endoscopic treatment of gastrointestinal perforations, fistulas and anastomotic leakages using the OTSC Ssystem in Korean patients.

A total of 19 patients were included, with gastrointestinal leakages from gastrojejunostomy sites (n=3), esophago-jejunostomy sites (n=3), esophago-gastrostomy sites (n=4), esophago-colonostomy sites (n=1), jejuno-jejunal sites (n=1), endoscopic full thickness resection site closures (n=2), Boerhaave’s syndrome (n=1), esophago-bronchial fistulas (n=2), gastro-colonic fistula (n=1), and colono-pseudocyst fistulas (n=1). The size of the leakage ranged from 5 to 30 mm (median diameter 10 mm). The median procedure time was 16 min. All cases were technically successful. Complete healing of the leakage was achieved in 14 of 19 patients (74%) using OTSC alone. There were no complications associated with the OTSC procedures.

The authors concluded that the OTSC System is a safe and effective method for the management of gastrointestinal defects, especially in cases of anastomotic leakage after surgery.
