Two Cases of Resection of Localized Sclerosing Encapsulating Peritonitis

ABSTRACT

Sclerosing encapsulating peritonitis (SEP), or abdominal cocoon, is generally recognized as a rare complication of continuous ambulatory peritoneal dialysis (CAPD), and the prognosis is very poor. The causes of SEP are multifactorial, including acetate in dialysate, recurrent peritonitis and dialysate con tamination with antiseptics containing chlorhexidine. Patients experience the characteristic symptoms and signs of nausea, vomiting, abdominal pain, and partial or intermittent bowel obstruction, and weight loss and malnutrition develop in severe case. We performed bowel resection on two patients with SEP, one idiopathic, and the other from CAPD. We briefly review the literature, and discuss the pathophysiology and the management of SEP.
