BACKGROUND
Right hepatic duct, formed by the confluence of the anterior and posterior right sectorial ducts, joins left hepatic duct to form common hepatic duct. This fashion of confluence does not prevail in all cases. The sectorial ducts can aberrantly meet left duct and rest of the ducts from the left lobe of liver. Presence of such variation imposes clinical importance during peri-hilar, split liver transplant surgery or cholecystectomy. Nepalese population has not been explored before disregarding clinical necessity as MRI or cholangiography.
METHODS
Descriptive cross sectional study was conducted in 107 cases dissecting the main portal fissure separating hemi liver and extrahepatic biliary confluences. Methylene blue dye was injected and bile duct wall was cut open to the study pattern of the confluence. Data analysis was done with Statistical Package for Social Sciences (SPSS) version 17.
RESULTS
Normal variant of confluence was found in 72% cases, aberrant right posterior sectorial duct joins left hepatic duct in 9.3% and aberrant right anterior duct or low insertion of the right posterior sectorial duct was found in 1.9%. 9.3% of cases there is no true right hepatic duct often described as triple confluence. 0.9% cases showed no particular pattern of confluence where common hepatic duct is formed by multiple confluence. Quadrate lobe was found to be draining into right anterior sectorial duct in a single case.
CONCLUSIONS
Right hepatic duct confluence pattern is variable and all the evidence occurs at the main portal fissure. Right sectorial duct may join the left duct avoiding normal confluence pattern. Right posterior sectorial duct may be inserted low in the common bile duct.

An 83-year-old man without specific symptoms was referred to our hospital for further evaluation and treatment of apparent double primary tumors of the cystic duct and common bile duct. Computed tomography showed contrast-enhanced solid tumors in the cystic duct and common bile duct. Magnetic resonance imaging showed that the bile duct tumor was isointense on T1-weighted images and had low intensity on T2-weighted images. In addition, the bile duct tumor showed high intensity on diffusion-weighted images. Endoscopic ultrasonography revealed the tumor of the common bile duct and endoscopic retrograde cholangiopancreatography demonstrated a filling defect in the bile duct. The cystic duct was not identified on endoscopic ultrasonography or endoscopic retrograde cholangiopancreatography. Transpapillary biopsy of the bile duct tumor showed adenocarcinoma. The patient was diagnosed with double primary tumors of the cystic duct and the common bile duct and underwent subtotal stomach-preserving pancreaticoduodenectomy. Microscopic examination with molecular profiling of the tumors revealed a high-grade noninvasive intracholecystic papillary neoplasm of the cystic duct extending into the common bile duct and forming a tubulopapillary neoplasm with invasion of the common bile duct.

This prospective study of 139 patients was performed for evaluation of the normal and abnormal distal cystic duct and cystic duct remnant after cholecystectomy. The normal distal cystic duct could be demonstrated in 51% of the patients with normal common bile duct and normal gallbladder. The average diameter of the normal distal cystic duct was 1.8 mm. In 95% of the patients, the distal cystic duct was located posterior to the common bile duct and, in 5% of the patients, anterior to the common duct. Echoes produced by cystic duct insertion into the common bile duct occasionally can be mistaken for stones in the common bile duct. These echoes, however, are not associated with acoustic shadowing. Sludge and stones could be demonstrated in the distal cystic duct as well as in the cystic duct remnant after cholecystectomy.

Mirizzi's syndrome is a rare complication of gallstone disease, that gallbladder lumen can lie alongside the common hepatic duct, resulting in inflammation and resultant bile duct stricture. Most cases are not identified preoperatively. Variations of the cystic duct and its point of union with the common hepatic duct are surgically important. Here, we present an unusual case of type I Mirizzi's syndrome with an uncommon anomalous cystic duct that long cystic duct joins common hepatic duct behind the duodenum. Also, there is a high bilirubin level due to gallstone and bile duct stone.
