Choledochal cyst is an uncommon premalignant anomaly. The morphology and pathogenesis of the premalignant lesion of cholangiocarcinoma arising from the choledochal cyst has not been well described. Herein, we report a rare case of bile duct adenoma arising from choledochal cyst with anomalous union of pancreaticobiliary duct (AUPBD). 50-year-old woman was admitted to our hospital with the complaint of epigastric pain. She had received common bile duct (CBD) exploration and choledocholithotomy and cholecystectomy 3 months earlier under the diagnosis of multiple CBD stones. Intraoperalive cholangiogram was not remarkable except CBD dilatation at that time. Endoscopic retrograde cholangiopancreatography revealed choledochal cyst with AUPBD and round filling defect which disappeared easily on the balloon cholaniogram. On magnetic resonance cholangiopancreatography, the filling defect was confirmed as 2 cm polypoid mass attached to the distal bile duct wall. At laparotomy, a soft whitish mass was palpable on the lower CBD. On histological examination, adenoma with focal carcinoma change arising from choledochal cyst was diagnosed.

The mucin-hypersecreting biliary papillomatosis is a premalignant neoplasm characterized by intraductal papillary proliferation involving extensive areas of the intrahepatic and/or extrahepatic bile duct. We report a case of mucin-hypersecreting biliary papillomatosis manifested as obstructive jaundice and diagnosed only by microscopy, with a review of literatures. A 74-year-old female, who had a past history of cholecystectomy about 13 years ago, was admitted to our hospital with jaundice. A CT scan showed marked dilatation of intrahepatic and extrahepatic bile duct without intraductal filling defect or extrabiliary mass. During endoscopic retrograde cholangiopancreatography, mucin extrusion from the duodenal major papilla and dilated common bile duct with amorphous filling defects was noted. Percutaneous transhepatic biliary drainage for cholangioscopy was failed. In the operation field, there was a lot of mucin but was no visible mass at the common bile duct with bare eyes and cholangioscopy. However, papilloma was detected at the random biopsy specimen by microscopy. The patient underwent partial resection of common bile duct and choledocho-jejunal anastomosis.

Small cell carcinoma is usually seen in the lung, but rarely involves the gastrointestinal tract including biliary tract. A 65 year-old man was admitted because of obstructive jaundice. A smooth-surfaced round intraluminal mass with proximal bile duct dilatation was seen in the proximal common bile duct on endoscopic retrograde cholangiogram. Under the diagnosis of bile duct cancer, pylorus-preserving pancreatoduodenectomy was done. Pathology revealed a 2 cm sized small cell carcinoma in the proximal common bile duct and distal common hepatic duct. On immunohistochemical stain, the tumor cells were positive for neuroendocrine markers CD56 and synaptophysin. After surgery, the patient received 5 cycles of adjuvant chemotherapy with VIP (etoposide, ifosfamide, and cisplatin) regimen. However, the patient died of liver metastasis 12 months after the diagnosis. We report a case of extrapulmonary small cell carcinoma arising from the common bile duct.

Xanthogranulomatous cholecystitis (XGC) is an unusual and destructive inflammatory process that is characterized by thickening of the gallbladder (GB) wall with a tendency to adhere to neighboring organs. XGC is often mistaken for GB carcinoma, and the frequency of the coexistence of these two lesions is approximately 10%. Therefore, in case of severe XGC, there is chance of either overlooking the carcinoma or other significant lesions. CA 19-9 is commonly measured in the serum of patients with hepatobiliary malignancies. Although CA 19-9 can be elevated in benign conditions such as cholestasis, pancreatitis, tuberculosis, thyroid disease etc., malignancy should be considered at first in setting of its significant and persistent elevation. We report a case of a 62-year-old man who showed continuously rising level of CA19-9 over 2000 U/mL after cholecystectomy for xanthogranulomatous cholecystitis and finally was diagnosed as cholangiocarcinoma by short-term follow up.

Multiple primary malignancy was reported firstly by Billroth in 1889. Recently, multiple primary malignancies are considered to increase due to improved survival rate of cancer patients, advanced diagnostic tools, and increased use of chemotherapy and radiotherapy. In Korea, several cases of triple primary malignancies were reported. However, four primary malignancies in gastro-intestinal tract was rarely reported. Recently, we experienced a 70 year-old male who was diagnosed with metachronous four primary malignancies in rectum, ascending colon, stomach, and ampulla of Vater. We report this rare case of metachronous four primary malignancies with a review of literature.

OBJECTIVETo assess the value of magnetic resonance imaging (MRI) in mid- and long-term complication monitoring after liver transplantation.

METHODSTwenty-one recipients receiving orthotropic liver transplantation between Feb 2003 and May 2005 were enrolled in this study. FLASH T(1)-weighted, T(2)-weighted fast spin echo, T(2)-weighted fat suppression, dynamic gadolinium-enhanced, MR cholangiopancreatography (MRCP) and three-dimensional dynamic gadolinium-enhanced FISP MRA images were obtained.

RESULTSOf the 21 patients, bile duct complications were detected in all cases and liver arterial and venous complications in 8 cases. Liver cancer relapse occurred in 5 cases and allograft failure in 4.

CONCLUSIONMR imaging allows effective monitoring of mid- and long-term complications of liver transplantation, which provides valuable clues for their clinical treatment.

Afferent loop syndrome is a rare complication which can occur in patients with Billroth II gastrectomy. Bile and pancreatic juice is congested at afferent loop in the syndrome. This syndrome can progress rapidly to necrosis, perforation, or severe sepsis, and therefore early diagnosis and swift surgical intervention is important. But, cases of endoscopic or percutaneous transhepatic drainage have been reported when surgical management was inappropriate to proceed. We report a case of afferent loop syndrome accompanying acute cholangitis developed after percutaneous transhepatic cholangioscopic lithotripsy for the retrieval of common bile duct stone in a patient who underwent Billroth II gastrectomy due to early gastric cancer. There was no other organic cause. We treated afferent loop syndrome successfully by performing balloon dilation of afferent loop outlet.

OBJECTIVE: We wanted to determine the technical and clinical efficacy of using a PTFE-covered self-expandable nitinol stent for the palliative treatment of malignant biliary obstruction. MATERIALS AND METHODS: Thirty-seven patients with common bile duct strictures caused by malignant disease were treated by placing a total of 37 nitinol PTFE stents. These stents were covered with PTFE with the exception of the last 5 mm at each end; the stent had an unconstrained diameter of 10 mm and a total length of 50-80 mm. The patient survival rate and stent patency rate were calculated by performing Kaplan-Meier survival analysis. The bilirubin, serum amylase and lipase levels before and after stent placement were measured and then compared using a Wilcoxon signed-rank test. The average follow-up duration was 27.9 weeks (range: 2-81 weeks). RESULTS: Placement was successful in all cases. Seventy-six percent of the patients (28/37) experienced adequate palliative drainage for the remainder of their lives. There were no immediate complications. Three patients demonstrated stent sludge occlusion that required PTBD (percutaneous transhepatic biliary drainage) irrigation. Two patients experienced delayed stent migration with stone formation at 7 and 27 weeks of follow-up, respectively. Stent insertion resulted in acute elevations of the amylase and lipase levels one day after stent insertion in 11 patients in spite of performing endoscopic sphincterotomy (4/6). The bilirubin levels were significantly reduced one week after stent insertion (p < 0.01). The 30-day mortality rate was 8% (3/37), and the survival rates were 49% and 27% at 20 and 50 weeks, respectively. The primary stent patency rates were 85%, and 78% at 20 and 50 weeks, respectively. CONCLUSION: The PTFE-covered self-expandable nitinol stent is safe to use with acceptable complication rates. This study is similar to the previous studies with regard to comparing the patency rates and survival rates.
