Acute Pancreatitis Complicating Liver Transplantation in a Case of Fulminant Hepatic Failure Due to Yellow Phosphorus Poisoning

Abstract

Yellow phosphorus (YP) is a general protoplasmic poison causing hepatic, cardiac, renal, and multiorgan failure. We report an unusual case of fulminant liver failure due to ratol (YP) poisoning complicated by acute pancreatitis postoperatively after liver transplantation. A 25-yr-old man presented with alleged consumption of approximately 7gm of Ratol paste. Serum amylase and lipase levels were 880 and 2423, respectively, and CT imaging of pancreas was normal. He developed fulminant liver failure, fulfilling King's college criteria and an living donor liver transplantation was performed. Intraoperatively fat saponification was seen at the root of mesentery. On postoperative day (POD) 13, he developed incisional wound dehiscence and he underwent laparotomy with extensive slough removal from the lateral aspect of wound. On POD 21, wound showed evidence of burst abdomen. CT abdomen revealed inflamed tail of pancreas with peripancreatic fat stranding and an exploratory laparotomy was performed again. Intraoperatively, walled-off necrotic collection was seen in the tail of the pancreas and necrosectomy was carried out. All the aforementioned re-explorations were carried out under steroid immunosuppression. He was restarted on tacrolimus on POD27. Graft function and cholestatic biochemistry improved progressively, and he was discharged and is on regular follow-up. YP is very toxic with rapid absorption and gets accumulated in liver causing acute liver failure. Acute pancreatitis in a patient after liver transplantation for fulminant liver failure owing to Ratol poisoning has not been reported in published English literature. Although clinically relevant pancreatitis is rare in ratol poisoning, despite elevated pancreatic enzymes, it is prudent to meticulously image pancreas before embarking on liver transplantation. In those with pretransplant elevation of pancreatic enzymes, it is desirable to follow up the enzyme values postoperatively.
