To examine diseases of the small intestines, the use of different methods including a small bowel series and push type enteroscopy have been employed, but these procedures are restrictive and have a low diagnostic accuracy rate. Recently, the use of double balloon enteroscopy has been introduced, and it is expected that this procedure will be of great value for research of diseases of the small intestine as it enables one to obtain a biopsy tissue sample and to perform diagnostic and therapeutic endoscopy while examining small intestine visually. We report as case of a patient that visited our institution complaining of abdominal pain, and the patient was diagnosed as suffereing from an intestinal obstruction due to a bezoar. The patient was treated by surgery after an investigation with the aid of a double balloon enteroscope.

Multiple primary cancer is defined as the multiple occurrence of malignant neoplasm in the same individual. Synchronous cancers are usually defined as finding the second cancer at the same time or within a 6-month period after the diagnosis of the primary lesion, and metachronous cancers are found at more than 6 months after the initial diagnosis. Multiple primary cancers have been increasing reported on due to prolonged lifespans and the improvement of diagnostic techniques. Nevertheless, triple synchronous cancers have been regarded as a relatively rare finding. We report here on an unusual case of triple synchronous cancer of early gastric cancer, carcinoid tumor of the ampulla of Vater and renal cell carcinoma.

Caroli's disease is defined as a communication between congenital cystic dilatation of the bile duct and the biliary system. Caroli's disease accompanied with autosomal dominant polycystic kidney disease is a very rare finding and the differential diagnosis between Caroli's disease with polycystic kidney disease and a polycystic liver is very important. A 67-year-old male patient was admitted to our hospital for hematochezia, and he underwent hemodialysis for chronic renal failure due to his autosomal dominant polycystic kidney disease. On colonoscopy, ulcero-infiltrative tumor was observed in the sigmoid colon. It was diagnosed as adenocarcinoma on tissue biopsy. On abdominal computerized tomography and magnetic resonance cholangiopancreatography, a number of simple cysts was observed in both kidneys and we were able to identify the communication between the dilated intrahepatic ducts and the intrahepatic cystic lesions, and so we diagnosed this patient as having Caroli's disease.
