We report a patient with HBV-related hepatocellular carcinoma (HCC) and refractory ascites who had received a peritoneal-venous shunt (PVS) 1 year before liver transplantation. Urgent surgical intervention following bowel obstruction and failure of immunosuppression therapy. No intestinal obstruction was found during an initial PVS. However, intestinal obstruction developed 2 wk after liver transplantation; and a cocoon abdomen was found upon exploration. This is the first reported case of cocoon abdomen caused by PVS and exacerbated by liver transplantation.
