Sclerosing Peritonitis Presenting 2 Years after Renal Transplantation in a Former CAPD Patient

Abstract

Sclerosing peritonitis (SP) is a rare but serious complication of peritoneal dialysis (PD), characterized by a fibrous peritoneal thickening. The etiology of this condition remains unknown but is likely to be multifactorial. Patients with SP almost invariably develop ultrafiltration and clearance failure. Although a number of pharmacologic drug treatment options have been tried with various results, surgical treatment and cessation of PD are almost always necessary and transfer to hemodialysis is the only practical option. Despite some evidence supporting the recovery of gastrointestinal function after renal transplantation in such patients, SP may very rarely appear much later after the cessation of PD and even after renal transplantation. We report an interesting case of a former PD patient who 2 years after renal transplantation presented with abdominal discomfort, vomiting, and malnutrition due to SP. Despite the initial conservative treatment, the symptoms persisted and a surgical treatment was decided upon. After that the patient recovered with no further complications. Although the appearance of SP after renal transplantation is extremely rare, it must be included in the differential diagnosis of every case of unexplained malnutrition and abdominal obstruction in a patient with a PD history.
