- We report a 15-year boy who presented with obstructive cholangiopathy and pancreatitis after blunt abdominal trauma. A magnetic resonance cholangiopancreatography showed dilated common bile duct, dilated hepatic ducts, and a suspicious choledochoduodenal fistula. An endoscopic retrograde cholangiopancreatography revealed a parapapillary choledochoduodenal fistula. An operation of choledochojejunostomy, excision of common bile duct, and cholecystectomy was done for recurrent cholangitis. Abdominal symptoms completely subsided one month later.
- We report a 3-year-old boy who presented with a foreign body impacted in the esophagus and had a poor tolerance of solid food since he was 5 to 6 months old. In the last 2 years, he developed progressive dysphagia, anorexia, vomiting, and poor weight gain. An esophagoscopy and barium esophagogram revealed an esophageal web in the distal third of the esophagus. Three courses of endoscopic balloon dilatation resulted in transient improvement in his dysphagia and vomiting; a follow-up barium esophagogram and esophagoscopy showed limited improvement of the esophageal stenosis.
- Inflammatory myofibroblastic tumor is a reactive proliferative lesion that occurs extremely rarely in the renal pelvis, especially during childhood. We report 1 such case that occurred in a child who presented with prolonged fever and abdominal pain. Ultrasonography and abdominal computed tomography revealed a left renal pelvic mass. She received conservative surgical treatment. The diagnosis was confirmed by pathological and immunohistochemical studies. Distinguishing inflammatory myofibroblastic tumor from other malignant renal pelvic tumors in children is essential to preventing unnecessary nephrectomy.
