The authors experienced three cases of cholangiocarcinoma associated with profuse mucin production. We intended to review and summarize the clinical features of these patients to emphasize the clinical importance of mucin-producing cholangiocarcinoma. All patients were female. Symptoms were mainly right upper quadrant pain and jaundice. Diagnosis was made by characteristic endoscopic retrograde cholangiographic findings and computed tomography. Bile ducts were dilatated and obstructive jaundice had developed as a result of the accumulation of mucin realeased by the tumor. Treatments were hepatic lobectomies for two intrahepatic cholangiocarcinoma patients and extrahepatic bile duct resection and hepaticojejunostomy for one patient. There was no postoperative complication. Pathologies were well differentiated papillary adenocarcinoma in two cases. Two patients are still living without recurrence for over three and four years respectively. One patient who had T4 lesion died of recurrence 38 months after operation. Conclusively, aggressive surgical treatment may be justified in the treatment of mucin hypersecreting cholangiocarcinoma even in advanced stage in view of the favorable outcome after radical operation. Further study is needed to clarify its biological behavior.

BACKGROUND AND AIMS: In the management of patients with extrahepatic bile duct carcinoma, histologic diagnosis is crucial to determine therapeutic modalities, to predict their outcomes, and to avoid an unnecessary operation. Though various methods were developed, none of them yielded satisfactory results. A combination of those methods was reported to yield superior sensitivity and specificity to a single method. To evaluate the diagnostic efficacy, endoscopic transpapillary biopsy (ETPB) and exfoliative bile aspiration cytology (BAC) was performed in 40 patients with extrahepatic bile duct carcinoma. METHODS: After visualization of the biliary tree and the lesion by endoscopic retrograde cholangiopancreatography (ERCP), ETPB (n=40) and BAC (n=28) was done in one session with or without endoscopic sphincterotomy (EST) and the results of two methods were analyzed. RESULTS: The final diagnoses were made by surgical pathology and by clinical follow-ups of more than a year. The locations of the 40 bile duct carcinomas were in the upper area in 25, the middle in 14 and the lower in 1. ETPB was performed in all patients and BAC in 28 patients. The overall sensitivity of the ETPB was 65.0% (26/40). According to the morphology and location, the sensitivity of ETPB was 65.6% (11/32) for sclerotic, 60.0% (3/5) for papillary, and 66.7% (2/3) for the protruding type, and 68.0% (17/25) for the upper bile duct lesion, 64.3% (9/14) for the middle, and 0% (0/1) for the lower. The overall sensitivity of the BAC was 71.4% (20/28). According to the morphology and location, the sensitivity of BAC was 80.0% (16/20) for sclerotic, 20% (1/5) for papillary, and 100% (3/3) for the protruding type, and 82.4% (14/17) for the upper bile duct lesion and 54.5% (6/11) for the middle bile duct lesion. When the two tests were combined, the sensitivity rose to 96.4% (27/28). CONCLUSIONS: A combination of ETPB and BAC is useful in making a histologic diagnosis in patients with bile duct carcinoma.

We report here on an extremely rare case of duplicated extrahepatic bile ducts that was associated with choledocholithiasis, and this malady was visualized by employing the minimum intensity projection images with using multi-detector row CT. The presence of duplicated extrahepatic bile ducts with a proximal communication, and the ducts were joined distally and they subsequently formed a single common bile duct, has not been previously reported.

Benign schwannomas arise in neural crest-derived Schwann cells. They can occur almost anywhere in the body, but their most common locations are the central nervous system, extremities, neck, mediastinum, and retroperitoneum. Schwannomas occurring in the biliary tract are extremely rare and mostly present with obstructive jaundice. We recently experienced a case of extrahepatic biliary schwannomas in a 64-yr-old female patient who presented with intra- and extrahepatic bile duct and gallbladder stones during a screening program. To the best of our knowledge, extrahepatic biliary schwannomas associated with bile duct stones have not been reported previously in the literature.

BACKGROUNDS/AIMS: In patients with obstructive jaundice due to malignant biliary tract stricture, a tissue diagnosis is essential because the various treatment options are available. The tissue biopsy from the biliary tree is difficult because of the focal, sclerotic, small annular nature and lower celluarity. Brush cytology is an effective method for obtaining a tissue from bile duct stricture, and the diagnostic sensitivity of endoscopic brush cytology is reported as between 40% and 70% from malignant bile duct strictures. In this study, we analyzed the diagnostic value of endoscopic brush cytology in patient with extrahepatic bile duct strictures. METHODS: The eight patients with extrahepatic bile duct strictures diagnosed with endoscopic retrograde cholangiopancreatography underwent endoscopic brush cytology and aspiration bile cytology. Brushing were taken using a Greenen cytology brush passed with a guide wire through the stricture. RESULTS: The final diagnoses were made by surgical pathology and clinical follow-up. The sensitivity of brush cytology (62.5%, 5/8) was significantly higher than the sensitivity of bile cytology (0%; 0/8). No procedure related complication occured. CONCLUSIONS: Endoscopic brush cytology would be an effective and a relatively safe method for tissue diagnosis in patients with malignant biliary obstruction.

Combined hepatocellular-cholangiocarcinoma (HCC-CC) with sarcomatoid features is an extremely rare primary liver cancer, of which only four cases have been reported. We report a case of sarcomatoid combined HCC-CC in a 60-year-old woman who complained of right upper quadrant pain and presented with a 7 cm mass in the S4 region of the liver in abdominal CT. Ultrasonography-guided needle biopsy diagnosed it as HCC, and left lobectomy of the liver followed. Microscopically, the tumor consisted of two portions: HCC portion showing trabecular pattern, which had partially sarcomatous area with spindle-shaped tumor cells, and CC portion with glandular pattern. Immunohistochemically, HCC portion reacted positively with alpha-fetoprotein while CC portion demonstrated positive reactivity with carcinoembryonic antigen and mucicarmine. Sarcomatoid cells reacted positively for cytokeratin. She died of tumor recurrence and hepatic failure 12 months after the operation. Combined HCC-CC has poor prognosis, and sarcomatoid HCC has high metastatic potential and poor prognosis compared with ordinary HCC.

We experienced one fatal case of biliary cast syndrome after cadaveric liver transplantation involving both intrahepatic ducts. A 58-year-old man underwent cadaveric liver transplantation because of hepatitis B virus related liver cirrhosis and concomitant hepatocellular carcinoma. Five weeks after the liver transplantation, postoperative course was complicated by development of acute cholangitis. Subsequent endoscopic retrograde cholangiography revealed diffuse intrahepatic bile duct strictures without filling defects. Percutaneous liver biopsy, which was done to exclude rejection, revealed biliary cast. Successful endoscopic removal was precluded due to its diffuse involvement. Because of the deterioration of patient's condition by refractory biliary obstruction and cholangitis, retransplantation from cadaveric donor was performed. Debridement of the biliary tree after graft removal yielded a near-complete cast of the intrahepatic ductal system. Biliary cast syndrome should be suspected when jaundice or cholangitis is associated with dilated ducts on abdominal imaging studies in cadaveric liver transplantation recipients. Initial therapeutic options include removal of biliary cast after endoscopic or percutaneous cholangiography. Although endoscopic retrieval of biliary cast by endoscopic retrograde cholangiopancreatography could be employed as a first-line management, other modalities such as endoscopic nasobiliary drainage, percutaneous transhepatic drainage, or retransplantation should be considered when complete removal is not feasible and the condition of the recipient deteriorates.

OBJECTIVETo explore the feasibility and outcome of combined hepatectomy, orthotopic liver transplantation and Whipple's pancreatoduodenectomy for radical excision of cholangiocarcinoma.

METHODSA 35-year-old female patient with unresectable cholangiocarcinoma underwent curative radical operation, which includes hepatectomy, orthotopic liver transplantation and pancreaticoduodenectomy of hilar bile duct carcinoma; immunosuppression followed an induction protocol with FK506 and steroids. Lamivudine and HBIg were used to prevent hepatitis B virus from infection again.

RESULTSPathologic examination revealed low differentiated cholangiocarcinoma and immunohistochemistry stains demonstrated positive expression of cytokeratin 9 and 17, carcinoembryonic antigen and the hepatocyte protein was negative. Neither the margins of resection nor the periductal lymph nodes were involved. The liver showed evidence of cholestasis and metastasis nod. The patient was hospitalized 32 days and came back to the previous work. He has been followed up for more than 14 months up to now and is currently alive without any evidence of recurrent cancer.

CONCLUSIONSFor some selected unresectable Klatskin's tumors, combined hepatectomy, pancreatoduodenectomy and orthotopic liver transplantation was justified. The radical methods maybe provide long-time survival and curative effect. Nevertheless, because of possible tumor recurrence and ethical controversy, the combined hepatectomy, pancreatoduodenectomy and orthotopic liver transplantation procedure has to be applied only with caution and indications.

PURPOSE: This study addressed the feasibility and effect of surgical treatment of metachronous periampullary carcinoma after resection of the primary extrahepatic bile duct cancer. The performance of this secondary curative surgery is not well-documented. METHODS: We reviewed, retrospectively, the medical records of 10 patients who underwent pancreaticoduodenectomy (PD) for secondary periampullary cancer following extrahepatic bileduct cancer resection from 1995 to 2011. RESULTS: The mean age of the 10 patients at the second operation was 61 years (range, 45-70 years). The primary cancers were 7 hilar cholangiocarcinomas, 2 middle common bile duct cancers, and one cystic duct cancer. The secondary cancers were 8 distal common bile duct cancers and 2 carcinomas of the ampulla of Vater. The second operations were 6 Whipple procedures and 4 pylorus-preserving pancreaticoduodenectomies. The mean interval between primary treatment and metachronous periampullary cancer was 20.6 months (range, 3.4-36.6 months). The distal resection margin after primary resection was positive for high grade dysplasia in one patient. Metachronous tumor was confirmed by periampullary pathology in all cases. Four of the 10 patients had delayed gastric emptying (n = 2) or pancreatic fistula (n = 2) after reoperation. There were no perioperative deaths. Median survival after PD was 44.6 months (range, 8.5-120.5 months). CONCLUSION: Based on the postoperative survival rate, PD may provide an acceptable protocol for resection in patients with metachronous periampullary cancer after resection of the extrahepatic bile duct cancer.
