Cystectomy is the gold standard treatment for patients with bladder cancer. Urinary diversion with ileal conduit and uretero-ileal anastomoses, as described by Bricker, is the most widely used surgical therapy because of the lower risk of postoperative complications in elderly patients and in those with co-morbidities. The Bricker technique involves the use of a segment of the ileum as a conduit to the skin, with a successive uretero-ileal-cutaneous anastomosis for each ureter [1]. The endoscopic approach to construction of the ileal conduit for urological obstruction is rarely reported [2]. We present the case of a patient who underwent cystectomy with a Bricker uretero-ileal-cutaneous anastomosis, who developed a fistula between the ileal conduit and an ileal handle. In May 2015, the patient underwent cystectomy with a Bricker uretero-ilealcutaneous anastomosis because of bladder transitional cell carcinoma. In October 2016, stool appeared in the drainage. The patient underwent radiological examination with contrast medium at another hospital, which revealed a fistula between the ileal conduit and an ileal handle. The patient was referred to our unit and an ileal conduit endoscopy (▶Fig. 1) was performed using a gastroscope, which showed stool leakage from an orifice between the two ureteral anastomoses (▶Fig. 2). An 11/6 traumaticteeth over-the-scope clip (OTSC), 9mm in diameter, was placed to close the leak (▶Video1), using an OTSC anchor to grasp the fistula (▶Fig. 3). Stool no longer appeared in the drainage 24 hours after OTSC placement. No adverse events occurred, and the patient was discharged 3 days after the procedure. There are no reports in the literature of the endoscopic closure of a fistula between the ileal conduit and an ileal handle. The current case demonstrates successful closure using an OTSC, which avoided damage to the uretero-ileal anastomoses. The OTSC is an excellent endoscopic therapeutic and conservative option in this particular and rare adverse event.
