Acute pancreatitis (AP) has been described after orthotopic liver transplantation but is uncommon in stable patients after the initial perioperative phase. The aim of this study is to review our experience with AP occurring more than 2 months after primary allografting and determine possible contributing factors plus patient outcome. A review of patient files and the unit database was performed. AP was diagnosed in 9 of 298 patients (3%) on 12 occasions. The incidence of AP was greater in men (8 of 163 men) than women (1 of 135 women; P <.04). Underlying factors to each episode of AP were biliary manipulation (4 of 12 episodes; 33%), history of recent alcohol ingestion (3 of 12 episodes; 25%), and malignancy in the region of the pancreas (2 of 12 episodes; 16%). AP was associated with a diagnosis of either hepatic artery thrombosis combined with biliary tract complications (P <.005) or malignancy (P <.004). In 7 of 12 episodes of AP (58%), conservative management alone was successful. In 3 of 9 patients (33%), subsequent surgery was required. One patient died of pancreatic malignancy. In conclusion, AP is uncommon in stable liver transplant recipients. Male sex, complications of hepatic artery thrombosis, and malignancy in the region of the pancreas are associated with AP in this study.
