Sclerosing peritonitis. Possible early diagnosis by computerized tomography of the abdomen.

Sclerosing peritonitis (SP) has come to be recognized as a serious complication of peritoneal dialysis (PD). However, diagnosis is often established at a late stage of the disease and at laparotomy. The use of computerized tomography (CT) of the abdomen in 2 patients, clinically suspected of suffering from SP, revealed loculated ascites, adherent bowel loops, bowel lumenal narrowing, and thickening of the peritoneal membrane. Such radiological changes in patients on PD seem highly consistent with a diagnosis of SP. We feel that CT of the abdomen may help in attaining an early, correct, and noninvasive diagnosis of SP. We recommend that CT of the abdomen be performed in any patient on chronic PD who has clinical manifestations suggestive of SP. Early diagnosis of SP can lead to early cessation of PD and hopeful recovery of the peritoneal membranes and space.
