Abstract

Introduction: Entero-neovesical fistula is a rare complication after radical cystectomy and orthotopic ileal bladder substitution. Typical presenting symptoms are faecaluria, pneumaturia, recurrent urinary tract infections and abdominal pain. Risk factors include history of pelvic radiation, chemotherapy and abdominal surgery, as well as diverticular colonic disease, inflammatory bowel disease and traumatic pelvic injury. The paucity of cases reported in the literature makes the management of this threatening complication very challenging. Conservative treatment has only anecdotally been reported. Case description: We describe two cases of entero-neovesical fistula with different presentation, which both required an immediate surgical treatment. The former patient was admitted to the emergency room with faecaluria, complete urinary incontinence and fever 2 years after radical cystectomy, and a fistula between the Y-shaped neobladder and the bowel anastomosis was detected. He had previously undergone chemotherapy because of tumour progression. Undiversion into an ileal conduit was required. The latter patient presented with faecaluria 20 days after an uneventful radical cystectomy, and a fistula between the Vescica Ileale Padovana neobladder and the sigmoid was documented. Treatment included resection of the sigmoid with several small diverticula, temporary ileostomy and closure of the neobladder fistula. Conclusion: Conservative treatment of entero-neovesical fistula can be attempted only in patients with small openings in the small bowel and no systemic symptoms. In all other cases, surgical treatment with bowel resection and either closure of the neobladder opening or undiversion should be the preferred option.
