Aim. To study the efficacy and other treatment outcomes of Ovesco clip closure of iatrogenic perforation. Methods. Retrospective study from 3 tertiary-care hospitals in Thailand. Patients with iatrogenic perforation who underwent immediate endoscopic closure by Ovesco clip were included. Patients’ demographic data, perforation size, number of Ovesco clips used, fasting day, length of hospital stay, success rates, and complication rate were recorded. Technical success was defined as closure achievement during endoscopic procedure and clinical success was defined as the patient can be discharged without the need of additional surgical or radiological intervention. Results. There were 6 iatrogenic perforations in 2 male and 4 female patients. The median age was 59 years (range 39–78 years). The locations of perforation were 5 duodenal walls and 1 rectosigmoid junction. The median perforation size was 13 mm (range 10–40 mm). The technical success was 100% and the clinical success was 83.3%. The success rates per locations were 100% in colon and 80% in duodenum, respectively. The median fasting time was 5 days (range 1–10 days) and the median length of hospital stay was 10 days (range 2–22 days). There was no mortality in any. Conclusion. Ovesco clip seems to be an effective and safe tool for a closure of iatrogenic perforation.
