Our aim in this work is to evaluate our experience in the management of colovesical and colovaginal fistulas with endoscopic over\u2010the\u2010scope (OTS) clips.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A retrospective review of all patients who underwent attempted endoscopic OTS clip management of colovesical and colovaginal fistulas between 2013 and 2020 was performed. Preoperative risk factors, operative details and postoperative outcomes are reported.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ten patients were identified. Fistula types were: colovesical (five), rectovesical (two), colovaginal (two) and rectovaginal (one). The aetiology of the fistula was diverticular disease in seven (70%) cases and surgical complication of pelvic surgery in three (30%). The mean defect age was 157\u00a0\u00b1\u00a098\u00a0days, the mean defect diameter was 4.5\u00a0mm (range 2\u201310\u00a0mm) and the mean fistula length was 15\u00a0mm (range 2\u201325\u00a0mm). In nine (90%) cases, fistula identification and cannulation were performed through the nonenteric lumen of the fistula. Initial management with an OTS clip was technically successful in eight (80%) patients. Of the eight patients who underwent OTS clip placement, long\u2010term success (mean follow\u2010up 218\u00a0days, range 25\u2013673\u00a0days) was achieved after initial intervention in four (50%) patients. One patient underwent serial OTS clip procedures and achieved long\u2010term success after four interventions; three patients have not undergone a repeat procedure after initial failure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Endoscopic management of colovesical and colovaginal fistulas with OTS clips offers a promising therapeutic option for patients with contraindications to conventional surgical management.
