BACKGROUND/AIMS: This study analyzed the factors associated with the yield of percutaneous transhepatic cholangioscopic biopsies in patients with bile duct cancer. METHODS: One hundred and sixteen patients who had received percutaneous transhepatic cholangioscopy and who had been confirmed as having bile duct cancer were enrolled in this study. RESULTS: When the location of the tumor was divided into intrahepatic (IHD), hilar and common bile duct, the biopsy yield was significantly higher in IHD cancer (93.7%) than in cases of hilar cancer (69.6%) (p<0.05). After a bile duct cancer had been classified as a nodular (n=31), papillary (n=27) or infiltrative type (n=58) upon cholangioscopic findings, the biopsy yields from nodular (96.8%) or papillary types (96.3%) were significantly higher than from infiltrative types (58.6%; p<0.01). However, cholangioscopic classification of bile duct cancer was the only independent factor affecting biopsy yield by multiple logistic regression analysis (p=0.001). The sensitivity of the combination of cholangioscopic biopsy and tumor vessel in overall bile duct cancer, especially in the infiltrative type, was significantly increased when it was compared with that for cholangioscopic biopsies (p<0.01) or for tumor vessels alone (p<0.01). CONCLUSIONS: The cholangioscopic classification of bile duct tumors might provide important clues to predict biopsy yield.

PURPOSE: To compare survival outcomes between bile duct segmental resection (BDR) and pancreatoduodenectomy (PD) for the treatment of middle and distal bile duct cancer. METHODS: From 1997 to 2013, a total of 96 patients who underwent curative intent surgery for middle and distal bile duct cancer were identified. The patients were divided into 2 groups based on the type of operation; 20 patients were included in the BDR group and 76 patients were in the PD group. We retrospectively reviewed the clinical outcomes. RESULTS: The number of lymph nodes (LNs) was significantly greater in patients within the PD group compared to the BDR group. The total number of LNs was 6.5 ± 8.2 vs. 11.2 ± 8.2 (P = 0.017) and the number of metastatic LNs was 0.4 ± 0.9 vs. 1.0 ± 1.5 (P = 0.021), respectively. After a median follow-up period of 24 months (range, 4–169 months), the recurrence-free survival of the PD group was superior to that of the BDR group (P = 0.035). In the patients with LN metastases, the patients undergoing PD had significantly better survival than the BDR group (P < 0.001). CONCLUSION: Surgeons should be cautious in deciding to perform BDR for middle and distal common bile duct cancer. PD is recommended if LN metastases are suspected.

PURPOSE: There are several reports that intraoperative transfusion may be a prognostic factor in periampullary cancer, but it is not conclusive. The purpose of this study is to clarify the prognostic significance of a transfusion following a pancreatoduodenectomy for periampullary cancers. METHODS: We analyzed 357 periampullary cancers from 1985 to 1997 (ampullary cancer: 130 cases; distal bile duct cancer: 141 cases; and pancreatic head cancer: 86 cases). Analytic variables for possible prognostic factors were various clinicopathologic factors combined with the presence of the perioperative transfusion. RESULTS: Of the overall 357 patients, 215 (60%) have received an intraoperative transfusion. The 5-year survival rate of the 130 ampullary cancer patients was 59%, and 76 cases (58%) underwent an intra operative transfusion. The 5-year survival rate of patients without intraoperative transfusion was 79% whereas that of patients with a transfusion was 47% (p=0.029). Following multivariate analysis, an intraoperative transfusion was an independent prognostic factor in ampullary cancer (relative risk: 2.174). In common bile duct cancer, the overall 5-year survival rate was 33%, and the 5-year survival rates of patients with (N=87) or without (N=54) a transfusion were 25% and 38% respectively, which showed a marginal statistical significance (p=0.0717). In pancreatic head cancer, the overall 5-year survival rate was 16% and there was no survival difference between transfused (N=52) and untransfused (N=34) patients. CONCLUSION: In the present study, intraoperative transfusion was an independent significant prognostic factor in ampullary cancer. Careful dissection to minimize intraoperative bleeding is mandatory in pancreatoduodenectomy for ampullary cancer.

BACKGROUNDS/AIMS: Mid bile duct cancers often involve the proximal intrapancreatic bile duct, and resection of the extrahepatic bile duct (EHBD) can result in a tumor-positive distal resection margin (RM). We attempted a customized surgical procedure to obtain a tumor-free distal RM during EHBD resection, so that R0 resection can be achieved without performing pancreaticoduodenectomy through extended EHBD resection. METHODS: We previously reported the surgical procedures of extended EHBD resection, in which the intrapancreatic duct excavation resembles a > or =2 cm-long funnel. This unique procedure was performed in 11 cases of mid bile duct cancer occurring in elderly patients between the ages of 70 and 83 years. RESULTS: The tumor involved the intrapancreatic duct in all cases. Deep pancreatic excavation per se required about 30-60 minutes. Cancer-free hepatic duct RM was obtained in 10 patients. Prolonged leakage of pancreatic juice occurred in 2 patients, but all were controlled with supportive care. Adjuvant therapies were primarily applied to RM-positive or lymph node-positive patients. Their 1-year and 3-year survival rates were 90.9% and 60.6%, respectively. CONCLUSIONS: We suggest that extended EHBD resection can be performed as a beneficial option to achieve R0 resection in cases in which pancreaticoduodenectomy should be avoided due to various causes including old age and expectation of a poor outcome.

Primary carcinoma of the bile duct is uncommon but not rare and its prognosis is poor even though long-termsurvival had been reported. The authors presented 62 cases of bile duct cancer, which were confirmed at YUMC fromJan. 1971 to Dec. 1981. The results were as follows; 1. The most prevalent age group was 6th decade and a male-tofemale ratio was 1.9:1. 2. Jaundice was the most common clinical manifestations(84%), and followed by right

Double common bile duct (DCBD) is a rare congenital anomaly among biliary anomalies. The anomaly has an important clinical implication because of its association with anomalous pancreaticobiliary ductal union (APBDU) and upper gastrointestinal cancers. In addition, if one of the two common bile ducts is mistaken for the cystic duct during surgery, bile duct injury is likely to occur. Treatment depends on the coexistence of concomitant cancer and APBDU. A 54-year-old male diagnosed of gastric cancer was referred for surgery. During surgery, we incidentally detected bile leak from the tubular structure around the hepatoduodenal ligament. We performed intraoperative cholangiogram by cannulizing into the tubular structure, and confirmed the tubular duct as the accessory bile duct with an ectopic drainage into the stomach, which was connected to the proximal common bile duct. In this study, we report a rare case of DCBD with an ectopic drainage into the stomach and review the literature.

Adenomyoma is a nonneoplastic lesion that can be found anywhere in the gastrointestinal tract, but it's rarely found in the extrahepatic bile duct. To the best of our knowledge, it is a completely benign lesion, but making a clear distinction from malignancy on preoperative evaluation is very difficult. Its clinical importance mainly lies in the possibility that they may be confused with carcinoma, leading to unnecessarily extensive surgical resections. We report here on a case of distal common bile duct adenomyoma that presented with right upper quadrant abdominal pain, and the preoperative examinations could not reveal whether the tumor was benign or malignant. It was finally diagnosed by histological examination after performing pylorus preserving pancreaticoduodenectomy.

The authors analysed retrospectively 56 cases of bile duct cancer, which were confirmed by histologically in47 cases and highly suuspected by clinically and radiologically in 9 cases. The resutls were as follows: 1. Themost prevalent age groups were 5th decade and a male to female ratio is 2.7:1. 2. The location of bile ductcarcinomas were common bile duct in 36%, common hepatic duct in 25%, junction in 13%, porta haptis in 11% anddiffuse involvement in 5%. 3. The accuracy of predicting obstruction is by ultrasonography was 76%. 4. Correctdiagnosis as bile duct carcinoma was made in 29 cases(43%). 5. The echogenicity of bile duct carcinoma compare toliver parenchyme was hyperechoic in 10 cases(34.5%), isoechoic in 14 cases(48.3%) and hypoechoic in 5cases(17.2%). 6. Posterior acoustic shadowing was seen in 5 cases. 7. The shape of obstruction site was abruptcut-off in 12 cases(41%), funnel shape in 7 cases(24%) and indistinct in 10 cases(35%).

Intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) is frequently found and has recently been recognized as a precancerous lesion leading to invasive carcinoma characterized by papillary growth of the ductal epithelium with rich mucin production and cystic dilatation of the hepatic duct. Surgical resection is the treatment of choice to avoid malignant transformation. Despite a growing number of studies on IPMN-B, there are few reports of its treatment aside from surgery. A 75-year-old woman was incidentally diagnosed as IPMN-B. Considering the patient's age, comorbidity, and preference, we recommended an argon plasma coagulation (APC) as local ablation therapy rather than surgical resection. There was no evidence of remnant tumor on percutaneous transhepatic cholangioscopy 4 weeks after the ablation of tumor mass by using APC. We report a rare case of IPMN-B successfully treated with APC.
