Purpose. Thorough understanding of biliary anatomy is required when performing surgical interventions in the hepatobiliary system. This study describes the anatomical variations of right bile ducts in terms of branching and drainage patterns, and determines their frequency. Methods. We studied 73 samples of cadaveric material, focusing on the relationship of the right anterior and posterior segmental branches, the way they form the right hepatic duct, and the main variations of their drainage pattern. Results. The anatomy of the right hepatic duct was typical in 65.75% of samples. Ectopic drainage of the right anterior duct into the common hepatic duct was found in 15.07% and triple confluence in 9.59%. Ectopic drainage of the right posterior duct into the common hepatic duct was discovered in 2.74% and ectopic drainage of the right posterior duct into the left hepatic duct in 4.11%. Ectopic drainage of the right anterior duct into the left hepatic ductal system and ectopic drainage of the right posterior duct into the cystic duct was found in 1.37%. Conclusion. The branching pattern of the right hepatic duct was atypical in 34.25% of cases. Thus, knowledge of the anatomical variations of the extrahepatic bile ducts is important in many surgical cases.

The right hepatic artery is an end artery and contributes sole arterial supply to right lobe of the liver . It also supplies the gall bladder, cystic duct, common hepatic duct and upper and middle part of common bile duct. Normal hepatic arterial anatomy occurs in approximately in 80% of cases, for the remaining 20% multiple variations have been described. Misinterpretation of anatomical variations of the right hepatic artery contribute to the major intraoperative mishaps and complications in hepatobiliary surgery. Materials and Methods: This descriptive study conducted on 50 cadavers in Department of Anatomy,Govt Medical College, Kozhikode to document the normal anatomy and different variations of right hepatic artery regarding its origin and relation with the common hepatic duct. Results : Right hepatic artery had its origin from proper hepatic artery in 47 (94%) cases, in one case the artery came from common hepatic artery, aberrant origin of right hepatic artery was seen in 4% cases, one case from celiac trunk directly and the other from superior mesenteric artery. Relation with common hepatic duct : In 46 cases (92%) the artery (normal and aberrant) passes posterior to common hepatic duct. In 6%, the artery was related anterior to common hepatic duct. In one case the artery was medial to the common hepatic duct. Conclusions : This study highlights the importance of knowledge of such anomalies since their awareness will decrease morbidity and help to keep away from a number of surgical complications.

Intraductal papillary mucinous neoplasms (IPMNs) are mucin-producing papillary neoplasms of the pancreatic or biliary ductal system that exhibit variable cellular atypia and cause ductal dilation. There are few reported cases of IPMN arising from the biliary tree in the literature. It has a higher propensity to undergo malignant transformation compared to IPMN arising from the pancreatic duct. An 80-year-old male underwent cross-sectional tomography (CT) imaging of the abdomen for evaluation of prostate adenocarcinoma, which revealed an incidental 2.3 × 2.7 cm soft tissue mass centered at the porta hepatis with diffuse dilatation of the left intrahepatic biliary ductal system and mild prominence of the right intrahepatic ductal system. Endoscopic ultrasound showed 2 adjacent hilar masses involving the common hepatic duct and the left hepatic duct with protrusion of the tissue into the lumen of the duct and upstream ductal dilatation. Endoscopic retrograde cholangiopancreatography revealed a large filling defect in the common hepatic duct extending into the left hepatic duct. A large amount of clot and soft tissue with a fish-egg appearance was retrieved. The patient underwent left hepatic lobectomy, radical resection of the common hepatic duct with Roux-en-Y hepaticojejunostomy to the right hepatic duct. Histopathological examination of the resected specimen revealed intraductal papillary mucinous neoplasm with diffuse high-grade dysplasia. Follow-up CT scan of the abdomen 2 months after the surgery was negative for any masses.

The right hepatic artery is an end artery and contributes sole arterial supply to right lobe of the liver. Misinterpretation of normal anatomy and anatomical variations of the right hepatic artery contribute to the major intraoperative mishaps and complications in hepatobiliary surgery. The frequency of inadvertent or iatrogenic hepatobiliary vascular injury rises with the event of an aberrant anatomy. This descriptive study was carried out to document the normal anatomy and different variations of right hepatic artery to contribute to existing knowledge of right hepatic artery to improve surgical safety. This study conducted on 60 cadavers revealed aberrant replaced right hepatic artery in 18.3% and aberrant accessory right hepatic artery in 3.4%. Considering the course, the right hepatic artery ran outside Calot’s triangle in 5% of cases and caterpillar hump right hepatic artery was seen in 13.3% of cases. The right hepatic artery (normal and aberrant) crossed anteriorly to the common hepatic duct in 8.3% and posteriorly to it in 71.6%. It has posterior relations with the common bile duct in 16.7% while in 3.4% it did not cross the common hepatic duct or common bile duct. The knowledge of such anomalies is important since their awareness will decrease morbidity and help to keep away from a number of surgical complications.

ABSTRACTUnder the prevailing overall Conditions of all veterinarians for the diagnosis of biliary diseases, application of surgical procedures and liver transplantation in Cats as carnivorous pet animal, and Rabbits as herbivorous pet animal and also as a human model in research. The present study was constructed on twelve native breeds of rabbits (Oryctolagus cuniculus) and eighteen adult domestic cats (Felis catus domesticus). We concluded that, in brief; the rabbit gall bladder was relatively small, fixed by several small hepato-cystic ducts to its fossa. The rabbit bile duct was formed commonly by the junction of the left hepatic duct and the cystic duct. The cystic duct was commonly fairly large, received the right hepatic duct that collected the right lobe in its route to enter the duodenum, the bile duct receives the branch of the caudate process of the caudate lobe. The present study revealed other four anatomic variations dealing with the shape and size of the feline native breed’s gall bladder from fundic duplication, bilobed, truncated fundus and distended rounded fundus. Commonly, the bile duct was formed by the triple convergence of the left and the right hepatic ducts with the cystic duct. However, in some exceptional cases a short common hepatic duct was formed. Sonographically, the normal gall bladder in rabbit appeared small, elongated with anechoic lumen bordered by right lobe laterally and quadrate lobe medially and has no visible wall, but in cat varied in conformation, bordered by the right medial lobe laterally and the quadrate lobe medially surrounded by echogenic wall.

Abstract The extrahepatic bile duct morphometry was determined by the analysis of the colangiographies performed at Medimar Imaging Services SRL of the “St. Andrei “in Constanta on a General Electric Brightspeed Select CT scanner 16 slides. For the left liver duct found a caliber of 3.5-6.6 mm, its length ranging from 4.2-24.9 mm, and the right hepatic duct had a caliber ranging from 4.2-7.2 mm, the length being between 3.0-25.0 mm. At the confluence of the two hepatic ducts an angle of 35.0-124.1° was formed. In the common hepatic duct we found a caliber of 3.9-9.7 mm, in length between 20.2-52.9 mm. Cystic duct having a size of 2.4 to 5.5 mm, finding a length ranging from 24.6 to 66.4 mm. The angle formed at the end of the cystic duct in the hepatic duct had a value between 6.2-55.8°, and between the cystic and biliary ducts an angle of between 88.5-170.4° was formed. The coledoc duct had a caliber of 3.1-14.7 mm and a length of 19.8-57.3 mm.

Abstract Vasculobiliary injuries (VBI) caused by cholecystectomies are infrequent but extremely serious. We report a case of a severe VBI successfully treated at our center. A 22-year-old woman underwent an open cholecystectomy as treatment for acute cholecystitis and bile duct stones. She was transferred to our center on postoperative Day 4 because of progressive jaundice and encephalopathy. After a proper investigation, we found an extreme VBI with infarction of the right hepatic lobe associated with complete interruption of the portal vein and proper hepatic artery flows and full section of the common hepatic duct. Right hepatectomy with portal—Rex shunt revascularization of the left hepatic lobe and Roux-en-Y hepaticojejunostomy to the left hepatic duct was done. The patient was discharged on the 60th postoperative day. Discussion: This case shows the successful surgical treatment of a severe cholecystectomy’s VBI, avoiding an emergency liver transplant.

Atresia of the biliary tract, or biliary atresia (BA), is a destructive, inflammatory disease in which progressive biliary tree fibrosis in an infant leads to obstruction of the bile ducts and, as a result, to cirrhosis of the liver. If untreated, progressive cirrhosis leads to death by 2 years. Biliary atresia can be divided into 3 types, each of which depends on the level closest to biliary obstruction. Type I (obstruction of the common bile duct), type II (patency of the bile ducts to the level of the common hepatic duct), type III (obstruction at the level of the gates of the liver). It is very important to distinguish between types of BA and conduct differential diagnosis with other cholestatic diseases. There are nonsyndromic, syndromic, and BA, combined with other malformations. In diagnostics, in addition to clinical manifestations and specific changes in blood biochemical parameters characterizing cholestasis, an ultrasound examination of the abdominal cavity organs, gepatobiliscintigraphy, magnetic resonance cholecystopancreatocholangiography, according to indications, a puncture biopsy of the liver and histological examination are performed. The main method of treatment is hepatoportoenterostomy according to Kasai, which must be performed no later than 3 months, and with liver cirrhosis and hepatic insufficiency, liver transplantation. Additional methods of treatment include the use of ursodeoxycholic acid, fat-soluble vitamins.

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.Keywords: Duct; hepatic; sectorial; variation.
