OBJECTIVE: To assess the diagnostic value of various ultrasound (US) findings and to make a decision-tree model for US diagnosis of biliary atresia (BA). MATERIALS AND METHODS: From March 2008 to January 2014, the following US findings were retrospectively evaluated in 100 infants with cholestatic jaundice (BA, n = 46; non-BA, n = 54): length and morphology of the gallbladder, triangular cord thickness, hepatic artery and portal vein diameters, and visualization of the common bile duct. Logistic regression analyses were performed to determine the features that would be useful in predicting BA. Conditional inference tree analysis was used to generate a decision-making tree for classifying patients into the BA or non-BA groups. RESULTS: Multivariate logistic regression analysis showed that abnormal gallbladder morphology and greater triangular cord thickness were significant predictors of BA (p = 0.003 and 0.001; adjusted odds ratio: 345.6 and 65.6, respectively). In the decision-making tree using conditional inference tree analysis, gallbladder morphology and triangular cord thickness (optimal cutoff value of triangular cord thickness, 3.4 mm) were also selected as significant discriminators for differential diagnosis of BA, and gallbladder morphology was the first discriminator. The diagnostic performance of the decision-making tree was excellent, with sensitivity of 100% (46/46), specificity of 94.4% (51/54), and overall accuracy of 97% (97/100). CONCLUSION: Abnormal gallbladder morphology and greater triangular cord thickness (> 3.4 mm) were the most useful predictors of BA on US. We suggest that the gallbladder morphology should be evaluated first and that triangular cord thickness should be evaluated subsequently in cases with normal gallbladder morphology.

Duodenal diverticula are detected in up to 27% of patients undergoing upper gastrointestinal tract evaluation with periampullary diverticula (PAD) being the most common type. Although PAD usually do not cause symptoms, it can serve as a source of obstructive jaundice even when choledocholithiasis or tumor is not present. This duodenal diverticulum obstructive jaundice syndrome is called Lemmel's syndrome. An 81-yr-old woman came to the emergency room with obstructive jaundice and cholangitis. Abdominal CT scan revealed stony opacity on distal CBD with CBD dilatation. ERCP was performed to remove the stone. However, the stone was not located in the CBD but rather inside the PAD. After removal of the enterolith within the PAD, all her symptoms resolved. Recognition of this condition is important since misdiagnosis could lead to mismanagement and therapeutic delay. Lemmel's syndrome should always be included as one of the differential diagnosis of obstructive jaundice when PAD are present.

OBJECTIVE: To evaluate the outcomes of patients undergoing percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy. MATERIALS AND METHODS: Fifty patients (mean age, 62.4 years; range, 27-86 years) who underwent percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy were included. The technical success rate, clinical success rate, complication rate, stent patency, patient survival and factors associated with stent patency were being evaluated. RESULTS: The median interval between the gastrectomy and stent placement was 23.1 months (range, 3.9-94.6 months). The 50 patients received a total of 65 stents without any major procedure-related complications. Technical success was achieved in all patients. The mean total serum bilirubin level, which had been 7.19 mg/dL +/- 6.8 before stent insertion, decreased to 4.58 mg/dL +/- 5.4 during the first week of follow-up (p < 0.001). Clinical success was achieved in 42 patients (84%). Percutaneous transhepatic biliary drainage catheters were removed from 45 patients (90%). Infectious complications were noted in two patients (4%), and stent malfunction occurred in seven patients (14%). The median stent patency was 233 +/- 99 days, and the median patient survival was 179 +/- 83 days. Total serum bilirubin level after stenting was an independent factor for stent patency (p = 0.009). CONCLUSION: Percutaneous transhepatic placement of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy is a technically feasible and clinically effective palliative procedure.

Hepatic peribiliary cysts (HPCs) are characterized by cystic dilatations of the peribiliary glands located throughout the branches of the biliary systems. Specifically, they are mainly located along the hepatic hilum and major portal tracts. The natural history and prognosis of HPCs are uncertain. In fact, almost all HPCs have been discovered incidentally during radiological examination or autopsy, and they are considered to be clinically harmless. Recently, several cases of HPCs associated with obstructive jaundice or liver failure were reported in patients with pre-existing liver disease in several studies. However, until now there have been no reports of such a case in Korea. Herein, we report a case of HPCs that show a disease course with a poor prognosis. These HPCs developed in a 47-year-old man with progressive alcoholic liver cirrhosis.

The aim of this study was to compare the clinical outcome and cost-effectiveness of preoperative biliary drainage (BD) methods in periampullary cancer, and to suggest guidelines for selecting the appropriate preoperative BD method. Between October 2004 and August 2010, 211 patients underwent pancreatoduodenectomy after preoperative BD. Clinical outcome and cost-effectiveness of the preoperative BD methods were compared based on the final drainage method used and on intention-to-treat analysis. There was no significant difference in drainage duration between percutaneous transhepatic biliary drainage (PTBD) and endoscopic BD groups (14.2 vs 16.6 days, respectively; P = 0.121) but daily diminution of serum bilirubin level was higher in the PTBD group (0.7 vs 0.6 mg/dL/day, respectively; P = 0.041). Based on intention-to-treat analysis, drainage duration was shorter (13.2 vs 16.5 days, respectively; P = 0.049), daily diminution of serum bilirubin level was higher (0.7 vs 0.6 mg/dL/day, respectively; P = 0.041). Medical care cost was lower (14.2 vs 15.7 x 10(3) USD, respectively; P = 0.040) in the PTBD group than in the endoscopic BD group. When selecting the preoperative BD method, practitioners should consider that PTBD is more cost-effective and safer than endoscopic BD.

Echinococcal disease can develop anywhere in the human body. The liver represents its most frequent location. Hepatic hydatid cysts may rupture into the biliary tract, thorax, peritoneum, viscera, digestive tract or skin. We report a rare case with rupture of the right hepatic duct into a hydatid cyst in a woman with known hydatid disease and choledocholithiasis. The increased intra-luminal pressure in the biliary tree caused the rupture into the adjacent hydatid cyst. The creation of the fistula between the right hepatic duct and the hydatid cyst decompressed the biliary tree, decreased the bilirubin levels and offered a temporary resolution of the obstructive jaundice. Rupture of a hydatid cyst into the biliary tree usually leads to biliary colic, cholangitis and jaundice. However, in case of obstructive jaundice due to choledocholithiasis, it is possible that the cyst may rupture by other way around while offering the patient a temporary relief from his symptoms.

Primary non-Hodgkin's lymphoma arising from the bile duct is extremely rare and the reported imaging features do not differ from those of cholangiocarcinoma of the bile duct. We report a case of a patient with extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue (MALT), who presented with obstructive jaundice and describe the distinctive radiologic features that may suggest the correct preoperative diagnosis of primary lymphoma of the bile duct. Primary MALT lymphoma of the extrahepatic bile duct should be considered in the differential diagnosis when there is a mismatch in imaging findings on computed tomography or magnetic resonance imaging and cholangiography.
