Sclerosing peritonitis after intestinal transplantation in children.
Long-term graft dysfunction and/or graft loss after intestinal transplantation (ITx) is a significant concern. Sclerosing peritonitis (SP) is a manifestation of chronic allograft failure and its presence may also include classic arterial obliterative arteriopathy (OA) as in chronic rejection. We describe the clinical presentation and management of SP occurring after ITx in children. Case records of 121 children undergoing ITx from 1990 to 2003 were reviewed. Three children (2.4%) presented with SP of the intestine allograft at a mean time of 6.6 yr following ITx as follows: age at Tx (yr) 8.2, and 3.7, with indication for ITx being gastroschisis in two and midgut volvulus in one patient. Type of ITx was isolated intestine in one and liver/intestine in two patients. Gross findings of SP included fibrosis/strictures; microscopically SP showed fibrosis/serositis, and fibrous adhesions; one patient had evidence of chronic allograft vasculopathy. All patients presented with clinical signs and symptoms of bowel obstruction and gastrointestinal contrast studies confirmed distal ileal obstruction (DIO). Operative findings confirmed SP and DIO in all patients; all patients were initially treated with distal segmental intestine allograft resection and lysis of the fibrous peel. All three patients recovered, although two required repeat laparotomy, there is only one long-term survival. SP after ITx may be a different manifestation of long-term intestine allograft degeneration. Surgical resection appears to offer palliation.
