Introduction The meticulously arranged hierarchical structure of the biliary tree is pivotal for liver function. This biliary tree is divided into intra and extrahepatic components. The anatomic variations of the biliary tree are notoriously common with studies reporting variations in 20% to 55% of the population in different parts of the world. This may result in misdiagnosis and serious injury to the biliary system during surgical procedures. Thus, accurate knowledge of the biliary tree is essential for the interpretation of radiological examination and presurgical planning for hepatob

SUMMARYDuring the laparoscopic cholecystectomy, a rare variation was found in a female patient. There was a large vessel exiting from liver parenchyma to gall bladder directly. It was pulsating; so was an unusual artery. The cystic artery was present properly at its usual anatomical site in Callot's triangle. The knowledge of these vascular variations is very significant in surgical interventions involving the biliary tree. It is of key importance for laparoscopic surgeons to know like this vascular variation to avoid catastrophic bleeding.The report emphasizes the vascular variation and the a

Summary The variations of the cystic duct are so common that only 30% of all humans present the classical anatomical arrangement between the common bile duct (CBD), the cystic duct, and adjacent arteries. Thus, it could be considered that anomalies of the biliary tree are a rule rather than an exception. Duplication of the cystic duct, however, is a very uncommon anatomical finding. In the Department of General and Digestive Surgery of the University Hospital Complex Albacete, a 73-year-old patient was admitted with symptoms of cholangitis.

We report a case of a 45-year-old woman with cholelithiasis, in which the cystic duct was found to join the right hepatic duct, an anatomical variation observed in only 0.3%–0.4% of cases.

AbstractObjective: The overall incidence of Phrygian cap is about 04%. It is an anomaly of gall bladder found congenitally. It can be a misguided pathological diagnosis often seen mimicking a liver mass on imaging of the hepatobiliary tree. Although Phrygian cap is a congenital anomaly, it does not show any pathological significance, In light of this condition, the purpose of this research was to find out the congenital anomalies of the gallbladder through magnetic resonance cholangiopancreatography (MRCP) along with its clinical significance.Methods: A total of 377 patients were selected with

Congenital malformations of the biliary tract represent a relatively rare entity with which surgeons, radiologists and clinicians are not adequately familiarized. We present a rare case of gallbladder duplication in a 40-year-old female, with the accessory cystic duct entering the left hepatic duct, which depicts the fifth reported case in the international bibliography. Our case illustrates the importance of detailed knowledge of anatomical malformations of the biliary tree, serving the purpose of a preoperative diagnosis of symptomatic cholelithiasis. It is also of paramount importance to ta

Intrahepatic lithiasis, endemic in East Asia, is increasing in Western countries and without proper treatment, may cause cholangitis, liver abscesses, biliary cirrhosis, and cholangiocarcinoma. Management may require endoscopic, percutaneous, or surgical approach to the bile duct. Anterograde approach through the stump of the biliary duct during hepatectomy has been reported only rarely. We present a case managed through an anterograde approach, which is a valid alternative that preserves the integrity of the main biliary tree.

Diseases of the bile ducts and gall bladder are more common than those of the liver parenchyma and ultrasound plays an important role in their diagnosis.

A departmental survey of personal methodology in the measurement of bile duct diameter was carried out by means of a representative diagram of a typical bile duct image configuration. The results revealed considerable differences in measurement practice, and factors that may explain the patterns of interobserver variation, among 20 respondents in this task, were postulated. There was considerable scope for error, by a factor of three times between the smallest and largest diameter selected noted within current practice variation. This reflects similar disparity found in the literature. Within

The echoendoscopic biliary drainage is an option to treat obstructive jaundices when ERCP drainage fails. These procedures compose alternative methods to the side of surgery and percutaneous transhepatic biliary drainage, and it was only possible by the continuous development and improvement of echoendoscopes and accessories. The development of linear setorial array echoendoscopes in early 1990 brought a new approach to diagnostic and therapeutic dimenion on echoendoscopy capabilities, opening the possibility to perform punction over direct ultrasonographic view.

Cholestatic jaundice is one of the most common neonatal conditions. BA, a correctable cholangiopathy, presents with cholestatic jaundice within the first weeks of life. The inflammation of bile ducts leads to progressive fibrosclerosis involving biliary trees, followed by cirrhosis and liver failure. With the use of modern molecular studies, this research aimed to define a novel pathogenesis by exploring variations. We performed genetic discovery by using supervised and unsupervised approaches. Ultimately, a combination of genetic variations and survival data was analyzed to strengthen the nov

During laparoscopic cholecystectomy, several factors increase the likelihood of bile duct injury (BDI). The most common cause of BDI during laparoscopic cholecystectomy is an inappropriate identification of the critical view of safety associated with acute and chronic inflammation, obesity, haemorrhage, and anatomical variants. Of all anatomic variants of the biliary tree, Blumgart type F has been reported as the least common, but allegedly it carries the biggest risk of BDI.

With the rise of laparoscopic cholecystectomy as the gold standard for treating gallbladder calculi andpolyps, subvesical bile ducts are gaining increased clinical importance. With the introduction of electrocautery insurgery, a large part of these tubular structures, although with interrupted continuity, do not show extravasation ofbile content postoperatively. Decreased bile production during general anesthesia and increased intraperitonealpressure also make diagnosis of injuries difficult.
