JOURNAL FREE ACCESSThe influencing factors of stent patency were analysed in 70 cases with tube stent and 21 cases with metallic stent. Univariate analysis showed that diabetes was prognostic factors influen cing patency of tube stent in contrast to metallic stent. Multivariate analysis using Cox's p ropotional hazards regression model showed that age and diabetes were prognostic factors influenci ng patency of tube stent.View full abstractDownload PDF (898K) -

JOURNAL FREE ACCESSA 41-year-old woman was seen at the hospital because of jaundice and general fatigue. Laboratory data on admission showed obstructive jaundice and increase of biliary and liver enzymes. Image examination revealed a cystic tumor with papillary prominence inside. The prominence was noticed as high echoic mass on ultrasonography and hypervascular mass on enhanced CT and angiography. Also the cystic mass had a few stones inside. The histopathological diagnosis was cholangiocellular carcinoma with cystic formation. It was so difficult to differentiate the tum or from biliary cystadenoma on image diagnosis. Eighteen cases, including the present case, of cholangiocellular carcinoma with cystic formation because of mucus production and necrotic degeneration of the tumor and so forth have been reported. However, it was very rare in such the present case and one other report that the cause of the cystic formation was regarded as not mucus production but the stricture of the bile duct by the tumor itself.View full abstractDownload PDF (5299K) -

JOURNAL FREE ACCESSA 73-year old man with choledocolithiasis suffered from acute pancreatitis after endoscopic biliary drainage with a double-pigtail stent. An abdominal X-ray showed the tip of the long (10 cm)stent moved into the duodenal third portion, and we considered that the straight part of the doublepigtail stent obstructed the orifice of the pancreatic duct. The stent was endoscopically removed, and a new short (4 cm) stent was placed. Then, his symptom disappeared and he was discharged in a good condition.View full abstractDownload PDF (1539K) -

JOURNAL FREE ACCESSThe patient was a 74-year-old man with a chief complaint of right hypochondralgia admitted to our hospital because of cholecystolithiasis. Abdominal CT and ultrasonography showed no maliganalthough, serum DUPAN-2 level was as high as 33,000U/ml. Because malignancy was suspected open cholecystectomy was performed. Pathological findings of the resected specimen revealed no evidence of malignancy. Immunohistological staining for DUPAN-2 demonstrated it to be positive reaction in epithelial cells.
The serum DUPAN-2 level is rarely increased in benign diseases such as cholecystolithiasis, probably due to biliary inflammation or the elevation of biliary manometory.
We need to estimate the change in DUPAN-2 level over time, since it is occasionally reduced in proportion to improvement of cholecystitis.View full abstractDownload PDF (2454K) -

JOURNAL FREE ACCESSWe report here a case of cholecystohepatic duct, an extremely rare anomaly. A 53-year-old female was admitted for suspicion of gallbladder and intrahepatic bile duct stones based on the ultrasonographic image. The patient was diagnosed as having a cholecystohepatic duct (right hepatic duct type) with stones by endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography. Following percutaneous transhepatic cholangio drainage, cholangio-scopic lithotomy was performed. On cholangiogram after lithotomy, the gallbladder strangely appeared atrophic and branched off directly from the bile duct. She has been well after lithotomy for two-year observation period without an operation. This is one case of cholecystohepatic duct with stones in which it was possible to obtain good bile excretion by ablation of stones only, and we consider that the indication for surgical treatment of cholecystohepatic duct should be decided after ablation of the stones.View full abstractDownload PDF (2278K) -

JOURNAL FREE ACCESSA 78-yr-old female with a hustory of biliary enzyme elevation for several years was admitted for evaluation of its aggravation. Cholangiography revealed biliary stenosis from the bilateral hepatic ducts to the upper portion of extrahepatic duct. Proper hepatic arterial CT showed homogenous thickening of the bile buct wall enhanced during the early phase, which turned hypodense during the late phase. This finding differed from eccentric wall thickening with late phase enhancement recognised in patients with extrahepatic bile duct cancer. Ballon dilation was performed under the diagnosis. She has been followed for 16 months without symptom. Cholangiography and CT have showed little change during this period.View full abstractDownload PDF (4915K) -

JOURNAL FREE ACCESSWe encountered a case of non-dilated pancreaticobiliary maljunction detected by helical DIC-CT.
The patient was a 55-year-old man whose chief complaint was epigastralgia. Abdominal ultrasonography revealed the presence of cholecystolithiasis accompanied by adenomyomatosis, pancreaticobiliary maljunction was suspected by helical DIC-CT and confirmed ERCP. Therefore, extrahepatic bile duct resection and biliary reconstruction were performed.
Non-invasive helical DIC-CT may be useful for screening a nd diagnosing non-dilated pancreaticobiliary maljunction.View full abstractDownload PDF (2807K)
