Enterovesical fistula, a rare complication of Meckel’s diverticulum: A case report

INTRODUCTION: Enterovesical fistulas usually result from diverticulitis, Crohn's disease, or colorectal cancer. A perforated Meckel's diverticulum can exceptionally result in an vesico-diverticulum fistula, as noted in only seven previously reported cases. CASE REPORT: A 35-year old Arabic male, quadriplegic,who presented epigastralgia evolving for a week, associated with abdominal distension and cloudy urine. On examination he was feverish (38.5 °C), dehydrated with tenderness in the entire distended abdomen; rectal examination revealed a hypotonic sphincter with no other abnormality. After investigations, acute peritonitis diagnosis was retained. Exploratory laparotomy revealed a vesico-diverticular fistula resulting from a performed Meckel’s diverticulum. Diverticulectomy, ileostomy and bladder sutures were performed after peritoneal cleansing. The postoperative course was uneventful. The anatomo-pathological examination confirmed the diagnosis of a perforated Meckel’s diverticulum that did not contain ectopic gastric or pancreatic tissue. CONCLUSION: Vesico-diverticular fistula resulting from a perforated Meckel's diverticulum is a rare complication. To our knowledge, this is only the fourth reported case which is not associated to inflammatory bowel disease.
