“…As reported in a recent multicenter study, the novel "fistula endoscopic submucosal dissection with clip closure" (FESDC) strategy is safe and feasible for endoscopic closure of gastrointestinal fistulas [3]; however, in our population, the technical success does not exceed 70 % in naïve fistulas. We previously reported the optimal results of a new closure device called the "mucosal adaptative ring to close endoscopic artificial ulcer" (MAR-CEAU) in endoscopic leak closure at the ulcer bed after endoscopic submucosal dissection (ESD) and persistent gastrocutaneous fistulas after percutaneous endoscopic gastrotomy [4,5]. This strategy has not previously been used for gynecological fistulas.…”
