Non-visible colovesical fistula located by cystoscopy and successfully managed with the novel Padlock® device for endoscopic closure

The development of novel mechanical endoscopic closure systems allows now the management of some gastrointestinal fistula types in a minimally invasive way. However, the correct location of the fistulous tract is essential to achieve successful endoscopic closure.
A 69-year-old woman with high risk for surgery presented with recurrent cystitis, pneumaturia, and enteruria 2 months after medical-treated diverticulitis. Computerized tomography demonstrated colovesical fistula but colonoscopy could not locate the fistulous opening. A cystoscopy was performed and the fistulous tract was shown using a guidewire. Then, a novel over-the-scope clip device Padlock® system was released in the sigmoid colon, with successful endoscopic closure through this not previously described collaborative approach between urologists, surgeons, and gastroenterologists.
