40 patients diagnosed as cholangiome of which 9 patients diagnosed by biliary cell, 13 patients diagnosed by CT scanner, and 18 patients diagnosed by operation. The biliary obstruction in the general hepatic tube occurred in 95% of patients in which the lesion involved in the 2 branches of liver was 75%. The image of cholangiome in the film of cholangiography found that biliary fair stenosid (62,5%).

Biliary adenoma is rarely found in the biliary tract, and there are currently few reported cases of tubular adenoma. Biliary adenoma most often occurs on the duodenal ampulla and the next most common site is on the common bile duct. Because the clinical signs, symptoms and the laboratory findings of these lesions may be similar to malignant biliary diseases, it is difficult to differentiate benign biliary adenoma from malignancy. Therefore, the diagnosis of these tumors tends to be delayed and physicians usually make the pathologic confirmation after a surgical operation. We experienced a case of the simultaneous occurrence of tubular adenoma of the common hepatic duct and gallbladder carcinoma, and all this was diagnosed and treated with common hepatic duct resection and a Roux-en-Y hepaticojejunostomy operation. To the best of our knowledge, this is the first report of biliary tubular adenoma accompanied with gallbladder carcinoma arising from tubulovillous adenoma.

Adenoma is a benign epithelial lesion with malignant potential and can be found at any site of the gastrointestinal tract. Adenoma of the common bile duct is a rare and unusual cause of bile duct obstruction. We report a case of tubulovillous adenoma of the common bile duct at the cystic duct opening. A 1.8X1.2X1 cm sized, round and lobulated mass was noted on abdominal sonogram, CT scan and endoscopic retrograde cholangiogram, and it was confirmed and treated by surgical resection.

Villous adenomas of the common bile duct are rare and accordingly it is difficult to render a firm preoperative diagnosis. They are the unusual cause of bile duct obstruction and can mimic malignant extrahepatic biliary tumors or stones. Until recently, only a few cases had been reported in the medical literature. Although some authors advocate open surgical excision, especially with recurrence or carcinomatous change, an endoscopic resection of a distal common bile duct adenoma is a viable alternative for those patients considered poor surgical risks. We present two cases of villous adenoma of the common bile duct diagnosed by an endoscopic biopsy and endoscopically resected, with review of the relevant literature on the subject.

BACKGROUND/AIMS: The technique of cholangioscopy has been used in the treatment of bile duct stones or for the diagnosis of various bile duct tumors. However, the cholangioscopic characteristics of the various types of bile duct tumors have not yet been clearly described. Therefore, we analyzed the results of our cholangioscopic examinations and classified the cholangioscopic findings according to tumor histology. METHODS: The cholangioscopic finding from 111 patients who had benign or malignant bile duct tumors were reviewed. The mucosal changes, the presence of neovascularization, and the patterns of luminal narrowing were analyzed and compared with the histologic diagnosis. RESULTS: Bile duct adenocarcinoma can be classified into three different types according to the cholangioscopic findings: nodular, papillary, and infiltrative. Bile duct adenoma, hepatocellular carcinoma and other types of bile duct cancer such as mucin-hypersecreting cholangiocarcinoma, biliary cystadenocarcinoma, squamous cell carcinoma also presented with their unique cholangioscopic characteristics. CONCLUSIONS: Bile duct tumors seem to show characteristic cholangioscopic findings according to their histology. Cholangioscopic examination seems to be a useful technique in the differential diagnosis of bile duct tumors.

Villous adenomas are benign epithelial lesions with malignant potential which can occur at any site in the gastrointestinal tract. They are usually encountered in the rectum and colon, less frequently in the small bowel and very rarely in the biliary trees. Nine cases of bile duct villous adenomas have been reported in the literature. However, 4 cases of bile duct villous adenomas have been reported in the Korean literature. Recently, we experienced a case of villous adenoma in the common hepatic duct in a 77-year-old man presenting with obstructive jaundice in which preoperative histologic diagnosis of villous adenoma played a critical role in managing this patient. Herein, we present a case report of bile duct villous adenoma and a review of the reported cases in Korea to help define and manage this rare disease entity in the bile ducts. In addition, confusing nomenclature of bile duct adenomas is discussed.

Bile duct adenomas are discovered incidentally during surgery or at autopsy. Especially, the occurrence of an adenoma in a choledochal cyst is very rare. Biliary carcinomas are known to be related to choledochal cysts. The association of an adenoma in a choledochal cyst with the carcinoma is not definite. We have experienced a case of a tubular adenoma arising in a choledochal cyst. Recently, a 24-year-old female was admitted with complaints of right upper quadrant abdominal pain and indigestion. Abdominal ultrasonography and ERCP showed a fusiform dilation of the common bile duct. During the operation, a tiny polyp was discovered in the cyst. We performed a cyst excision and a Roux-en-Y hepaticojejunostomy. On microscopic examination, the polyp was diagnosed as a tubular adenoma.

Benign tumors of the extrahepatic bile duct are rare. They occur mostly in the common bile duct. Among them, papillomas and adenomas are most common. We experienced a case of villous adenomas in the common bile duct and also in the cystic duct. The ultrasound and the CT scan of the abdomen revealed markedly dilated common bile duct, subtle filling defect, and irregular mass narrowing the lumen of the common bile duct. The cholangiogram demonstrated movable, feathery, and marginated papillary mass with tumors, a broad base, and biopsy of this mass was done through the PTBD. The biopsy specimen showed villous adenoma. Even though it was diagnosed as benign, cholecystectomy and excision with Roux-en-Y hepaticojejunostomy was performed because of the high incidence of recurrences and malignant potential.
