Endoscopic management of iatrogenic EUS-related duodenal perforations with over-the-scope clips.

Iatrogenic endoscopic ultrasound (EUS) perforations are life-threatening adverse event and to date, surgery has been the main treatment for them. The aim of this study was to assess feasibility and safety of conservative treatment with over-the-scope clips (OTSC).  We performed a retrospective study, including iatrogenic EUS duodenal perforation with conservative endoscopic management from 2011 to August 2018. Patients who initial had surgical management were excluded.  In 8504 EUS procedure occurred, 13 perforations occurred (0.15 %). Eleven patients were included in the study, all women. Mean patient age was 75 years (range 68 - 88). Eighth of 11 perforations (72.7 %) were due to a radial probe and three of 11 (27.3 %) were due to a curvilinear probe. Eleven procedures (100 %) were performed as diagnostic. Defect size ranged from 10 to 15 mm. All procedures were successful. Three of eleven patients (27 %) had a stay in intensive care unit for less than 72 hours and length of total hospital stay ranged from 3 to 22 days.  Conservative endoscopic treatment of Iatrogenic EUS perforation, with OTSC is feasible, efficient and safe.
