Intestinal fistula accompanied by recurrent peritonitis associated with peritoneal dialysis: a case report

BACKGROUND: Intestinal perforation from peritoneal dialysis is rare, but the resulting complications are serious. Some patients do not necessarily have symptoms, and it can be difficult to differentiate their condition from PD-related (peritoneal dialysis-related) peritonitis, which may lead to misdiagnosis. Here we report a peritoneal dialysis patient with intestinal fistula associated with recurrent peritonitis. CASE PRESENTATION: A 44-year-old man had been treated for more than 6 years with peritoneal dialysis for chronic kidney disease stage-V. Abdominal computed tomography and electronic colonoscopy revealed an appendiceal fossa with adjacent fistula. The peritoneal dialysis catheter was removed, and the patient recovered with no recurrence of complications. CONCLUSION: We report a case of a rare complication of peritoneal dialysis. The intestinal fistula in this patient was mainly caused by recurrent peritonitis and removal of the catheter could control the peritonitis.
