A 10-year-old-girl who underwent Roux-en-Y cystojejunostomy under the diagnosis of choledochal cyst at another hospital at the age of 3 months was referred to our hospital due to abdominal pain. Abdominal ultrasonography (USG) and computed tomography (CT) showed the type I choledochal cyst and multiple gall bladder stones. Severe inflammation and adhesion made difficulty of radical resection and only partial resection of choledochal cyst with Roux-en-Y hepaticojejunostomy could be performed. She complained of intermittent abdominal pain, fever, nausea and vomiting 2 1/2 years after the second operation. Follow-up abdominal CT scan showed the polypoid nodular lesion in the remnant choledochal cyst and suspicious metastatic lesion in the segment 7 of the liver. The duodenum was obstructed by the mass arising from the remnant choledochal cyst. The USG-guided liver biopsy revealed the moderately differentiated adenocarcinoma. A secondary palliative gastrojejunostomy was performed to relieve the obstruction of duodenum. She died of hepatic insufficiency 4 months later of third operation.

An 11-year-old girl with history of two previous attacks of acute pancreatitis was admitted to another hospital. On physical examination, she had epigastric tenderness. Laboratory studies included amylase of 657IU/L and lipase of 3131IU/L. Abdominal computed tomography (CT) scan suggested necrosis in 30% of pancreas. To establish the cause of recurrent pancreatitis, endoscopic retrograde cholangiopancreatography (ERCP) was performed after acute pancreatitis subsided. Duodenoscopic view revealed a blind sac covered by normal duodenal mucosa at the second portion of the duodenum. Barium upper gastrointestinal series (UGI) showed a large sac separated from adjacent duodenal lumen by a radiolucent band. Diagnosis of intraluminal duodenal diverticulum (IDD) was made and endoscopic excision was considered. The apex of the diverticulum was incised endoscopically using a needle knife papillotome. At a follow-up endoscopy one day after procedure, bleeding from the incised edge of diverticulum was noted. Despite hemoclipping and injection of hypertonic saline-epinephrine solution by under the endoscopy, hemostasis was unsuccessful. She was transferred to the Kyungpook National University Hospital after resuscitation. Open duodenotomy and excision of the diverticulum were performed. She has recovered well from surgery and remains asymptomatic.
