Gastric outlet obstruction caused by a heterotopic pancreas in a pregnant woman: report of a case.
A 26-year-old Japanese woman who was 23 weeks pregnant presented with nausea, vomiting, and abdominal pain. Gastroduodenal endoscopic examination revealed an oval-shaped submucosal tumor obstructing the gastric outlet at the prepyloric area in the stomach. Magnetic resonance imaging showed a 5-cm cystic tumor and we suspected a degenerated gastrointestinal stromal tumor. No other radiological tests were done because of the associated risks to the fetus. Distal gastrectomy was performed and a histological diagnosis of heterotopic pancreas was confirmed. The patient had an uneventful postoperative course and was discharged 19 days after her operation. She delivered a healthy, full-term male infant 3 months later. This case of an ectopic pancreas obstructing the gastric outlet in a pregnant woman is reported and discussed due to its rarity.

Pancreatic tuberculosis.
A 63-year-old Japanese man visited our institute with fever of unknown origin. Findings on preoperative imaging modalities were consistent with pancreatic carcinoma, but a positive tuberculin skin test indicated tuberculosis infection. Negative results for MycobacteriumDNA polymerase chain reaction from sputum and bone-marrow aspiration biopsy specimens ruled out pulmonary and miliary tuberculosis, respectively. Positron emission tomography (PET) with 2-[fluorine-18]-fluoro-2-deoxy- d-glucose (FDG) showed multiple labeled spots within the pancreas body and chest. Distal pancreatectomy was performed with a diagnosis of suspected pancreatic carcinoma, but the histological and microbiological diagnosis was Mycobacterium infection. A rare case of pancreatic tuberculosis evaluated by FDG PET is reported and discussed herein.

Percutaneous sclerotherapy for intractable external biliary fistula after hepatectomy.
A 59-year-old man was diagnosed with cholangitis and a liver abscess caused by intrahepatic stones and underwent a hepatectomy of the left lobe and a side-to-side hepaticojejunostomy. After the operation, the patient developed an intractable external biliary fistula in the left remnant medial region. For the purpose of closing the fistula as a conservative treatment, an injection of 95% dehydrated ethanol was started after confirming the absence of any communication with the central bile duct; 1.5-5 ml was used for each injection, and the tube was clamped for 2 hours after injection. The excretion of bile juice decreased from the second injection, the excretion became serous, and the fistula completely closed after about 2 months without any particular complications. Percutaneous sclerotherapy by the injection of ethanol was found to be useful for closing a noncommunicating external biliary fistula.
