Sclerosing encapsulating peritonitis in a child secondary to peritoneal dialysis.

ABSTRACT

Sclerosing encapsulating peritonitis, or "abdominal cocoon," is a rare but serious complication of continuous ambulatory peritoneal dialysis. It is characterized by the diffuse appearance of marked sclerotic thickening of the peritoneal membrane resulting in intestinal obstruction. A 14-year-old adolescent boy with a history of end-stage renal failure on continuous ambulatory peritoneal dialysis presented with symptoms of acute intestinal obstruction. A computed tomography scan of the abdomen revealed distended small bowel loops clustered and displaced to the right upper quadrant. The overlying peritoneum was markedly thickened and calcified. Laparotomy confirmed the diagnosis of sclerosing encapsulating peritonitis and the patient was treated with excision of the fibrocollagenous membrane. Postoperatively, he had prolonged ileus requiring parenteral nutritional support and peritoneal dialysis was restarted on postoperative day 10. A high degree of cognizance is needed to facilitate diagnosis and treatment of this uncommon and potentially life-threatening condition.
