Webs are diagnosed by their characteristic appearance on imaging studies, typically appearing as thin, radiolucent rings with or without dilatation of the organ proximal to it. Like in other organs, the etiology of webs in the common bile duct is controversial. Some webs are thought to be congenital, whereas others occur in the presence of chronic inflammation, suggesting a pathogenic relationship. We report a case of a common bile duct septum in association with numerous large black pigment stones in a 62-year-old woman. The patient was treated by cholecystectomy with T-tube insertion.

BACKGROUND/AIMS: Sustained HBV DNA reduction is necessary for biochemical remission, histological improvement, and prevention of complications. We analyzed the time taken from HBV DNA loss to viral breakthrough after antiviral treatment in patients with chronic hepatitis B (CHB). The early fall of the HBV DNA level to undetectable levels assessed really whether it is related to late breakthrough. METHODS: A total of 91 patients whose HBV DNA levels dropped below undetectable levels were chosen from lamivudine-treated 306 patients and were analyzed retrospectively. The patients were divided into 4 groups (A< or =12, 1248 wk) according to the time taken for the HBV DNA to decrease below undetectable levels. HBV DNA level was determined every 3 months. RESULTS: The mean time taken for loss of HBV DNA was 34+/-28 wk. The baseline ALT differed significantly among groups (A: 382+/-274, B: 340+/-30, C: 166+/-92, D: 54+/-100 IU/L) (p=0.007). Fifty nine of the 91 patients (64.8%) experienced viral breakthrough. The mean interval between HBV DNA loss and viral breakthrough was 65+/-40 wk and differed significantly between group A, B (82+/-43 wk) and group C, D (56+/-28 wk) (p=0.015). In multivariate analysis, only HBV DNA loss within 24 wk, was found to be independently associated with late viral breakthrough (p=0.035). Undetectable HBV DNA after 24 wk was associated with high odd ratio of 3.24 (95% CI, 1.09-9.67). CONCLUSIONS: HBV DNA loss within 24 wk after antiviral treatment could predict the late breakthrough.

BACKGROUND/AIMS: The treatment of choice of intraductal papillary mucinous neoplasm (IPMN) is partial pancreatic resection with complete excision of this potentially malignant lesion, thus preserving sufficient pancreatic tissue to ensure endocrine and exocrine functions. This strategy, however, requires a reliable preoperative assessment of the highly variable extension of IPMN. We performed this study to determine the role of intraductal ultrasonography (IDUS) in predicting the extension of IPMN and selecting the resection methods of pancreas. METHODS: A preoperative assessment of IPMN by IDUS was performed in 12 patients who underwent a surgical resection of IPMN. According to the preoperative localization of IPMN by IDUS, various types of limited pancreatic resections were planned. The histologic examination of the frozen section of the pancreatic cut surface was performed in all patient. In the cases of tumor involvement as cut surface margin, a modification of the planned pancreatic resection was done. RESULTS: Technical success was achieved in all 12 cases (100%). There were positive tumor margin of cut surfaces in 2 patients. Of 10 cases whose frozen tissue evaluation of the pancreatic cut surface had been negative at first, one patieat has turned out to be margin positive in permanent section examination, finally. Overall accuracy of IDUS in predicting the continuous extension of IPMN was 75%. CONCLUSIONS: IDUS is a reliable diagnostic modality to guide the resection extent of the pancreas in patients with IPMN.

BACKGROUND/AIMS: Photodynamic therapy (PDT) has a promising effect on non-resectable hilar cholangiocarcinoma. The aim of this study was to compare overall survival of PDT plus biliary drainage versus biliary stent alone in advanced hilar cholangiocarcinoma. METHODS: Twenty patients who were treated with endoscopic biliary drainage alone (Group A) and 27 patients treated with PDT under percutaneous cholangioscopy and additional percutaneous biliary drainage (Group B) were analyzed retrospectively. RESULTS: The mean bilirubin level declined effectively in both group after treatment. One-year survival was 28% in group A, 52% in group B (p<0.05). Median survival time was 288 days in group A, 558 days in group B (p=0.0143). CONCLUSIONS: PDT under percutaneous cholangioscopy seems to be more effective in extending survival than biliary drainage alone in advanced hilar tumor. To investigate whether PDT can increase survival rates, further prospective, randomized study is needed.

BACKGROUND/AIMS: Presence of enhanced mural nodules, which can be visualized using computed tomography (CT), is one of high-risk stigmata in branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs). Conversely, the absence of enhanced mural nodules on preoperative imaging does not exclude malignant risk. The present study aimed to investigate other morphological features as predictors of malignancy in “pure” BD-IPMNs without enhanced mural nodules on CT. METHODS: This retrospective study included 180 patients with surgically confirmed “pure” BD-IPMNs of the pancreas and no enhanced mural nodules on preoperative CT. The study was conducted at 15 tertiary referral centers throughout South Korea. Univariate and multivariate analyses were used to identify significant predictors of malignancy. RESULTS: BD-IPMNs with low-grade (n=84) or moderate-grade (n=76) dysplasia were classified as benign; those with high-grade dysplasia (n=8) or invasive carcinoma (n=12) were classified as malignant. The multivariate analysis revealed that cyst size ≥30 mm (odds ratio, 8.6; p=0.001) and main pancreatic duct diameter ≥5 mm (odds ratio, 4.1; p=0.01) were independent risk factors for malignancy in “pure” BD-IPMNs without enhanced mural nodules on CT. Endoscopic ultrasound detected enhanced mural nodules (6/82) that had been missed on CT, and two IPMNs with enhanced mural nodules were malignant. CONCLUSIONS: In patients with “pure” BD-IPMNs who have no enhanced mural nodules on CT, cyst size ≥30 mm and main pancreatic duct diameter ≥5 mm may be associated with malignancy.
