Purse-string sutures using novel endoloops and repositionable clips for the closure of large iatrogenic duodenal perforations with single-channel endoscope: a multicenter study
Serious complications due to perforation restrict the development of duodenal endoscopic treatment. The key stage for remediation is the successful endoscopic closure to prevent peritonitis and the need for surgical intervention. This report aimed to present a new simple method for the closure of large iatrogenic duodenal perforations with purse-string sutures using the novel endoloops and repositionable clips through a single-channel endoscope.
A total of 23 patients with iatrogenic duodenal perforations ≥ 1 cm were retrospectively studied who were presently treated by purse-string sutures using the novel endoloops and the repositionable hemostasis clips with the single-channel endoscope at four institutes. During and after the procedure, a 20-gauge needle was used to relieve the pneumoperitoneum or subcutaneous emphysema. Finally, a gastroduodenal decompression tube was placed.
The median maximum diameter of iatrogenic duodenal perforations was 1.65 cm (range 1.0–3.0 cm). Complete endoscopic closure of all 23 perforations was achieved. No patient had severe complications such as peritonitis. The wounds were healed and no obvious duodenal stricture was observed in all cases after 3 months.
Purse-string sutures using the novel endoloops and repositionable endoclips through single-channel endoscope were feasible, effective and easy methods for the closure of large duodenal iatrogenic perforations.
