ABSTRACT
Congenital hepatic fibrosis is an uncommon fibrocystic disorder affecting the intrahepatic bile ducts. It has autosomal recessive inheritance. The main consequence of this condition is portal hypertension and it is often misdiagnosed as cirrhosis. Patients with congenital hepatic fibrosis usually present during childhood or early adolescence with oesophageal variceal bleeding. Portosystemic shunt surgery is the treatment of choice for these patients as the risk of postoperative hepatic encephalopathy is low. We report a patient with congenital hepatic fibrosis who presented with oesophageal variceal bleeding at the age of 16 years, initially misdiagnosed as having cryptogenic liver cirrhosis. The patient experienced two further episodes of oesophageal variceal bleeding in subsequent years. She eventually underwent portosystemic shunt surgery. One year after the operation, the shunt remained patent on Doppler ultrasonography, and there had been no further episodes of variceal bleeding post-surgery.

Patients with neurofibromatosis type 1 are at increased risk of developing carcinoid tumours of the duodenum, particularly in the ampulla of Vater. Aggressive surgery with pancreatoduodenectomy is recommended for all ampullary carcinoid tumours because of their propensity to metastasise. We report a case of a 43-year-old woman with neurofibromatosis type 1, who presented with recurrent epigastric pain for 15 months. Evaluation using magnetic resonance cholangiopancreatography and side-viewing duodenoscopy revealed a submucosal tumour at the ampulla of Vater causing pancreatobiliary ductal obstruction and dilation. The ampullary tumour was overlooked initially by forward-viewing endoscopy. The patient subsequently underwent pancreatoduodenectomy. Histological examination of the surgically resected specimen confirmed the presence of a carcinoid tumour, with metastasis to peri-pancreatic lymph nodes. She remained asymptomatic 10 months after surgery.
