We present here the case of a continuous ambulatory peritoneal dialysis (CAPD) patient who developed sclerosing calcifying peritonitis with gross macroscopic calcification of the small bowel, a rare and life-threatening complication of sclerosing peritonitis. A 40-year-old female had been on CAPD for 7 years. A peritoneal biopsy during an open cholecystectomy for cholelithiasis showed sclerosing peritonitis, but the patient refused to change dialysis modality. She remained free of symptoms for 3 years, but then was admitted with cloudy effluent, abdominal pain, and referred pain to the left shoulder. A white blood cell count showed 25,000 cells/microL, and a peritoneal cell count showed 1000 cells/microL. An abdominal computed tomography scan was nondiagnostic. The patient was started on intraperitoneal antibiotics, but 3 days later she was taken for surgery because of acute abdomen. Laparotomy revealed a tanned and thickened peritoneum and a small bowel with significant fibrosis and foci of calcification on the antimesenteric surface. Enterectomy and primary anastomosis was performed. Pathology revealed extensive mural fibrosis, calcium deposition, and localized inflammatory infiltration of the small bowel. The patient developed an anastomotic leak and, despite a second operation, died in the intensive care unit from septic shock. Although some authors report successful outcomes in similar cases by using surgery or other treatments (parenteral nutrition, immunosuppression), or both, we urgently recommend that, if sclerosing calcifying peritonitis is diagnosed, the patient be switched promptly to hemodialysis.

(2011)Most episodes of peritoneal dialysis (PD)-related peritonitis could be attributed to a single organism, but in almost 10% of peritonitis episodes multiple organisms are identified. Polymicrobial peritonitis is often related ...
