BACKGROUND This retrospective study aimed to investigate the incidence of each type of accessory hepatic duct by drip infusion cholangiography with CT (DIC-CT). METHODS Five hundred sixty nine patients who underwent preoperative DIC-CT and laparoscopic cholecystectomy were reviewed. Accessory hepatic ducts were classified as follows: type I (accessory hepatic ducts that merged with the common...

The common bile duct may present a number of anatomical peculiarities regarding its size, course and relations, which should be taken into consideration by the anatomists and by the surgeons as well, during the surgery of the gallbladder, pancreas and duodenum. In the present study, we have analyzed the anatomical peculiarities of the common bile duct in 150 adult corpses of both sexes from the...

Background: Persistent thyroglossal duct leads to a fibrous cyst formation named thyroglossal cyst which is the most common form of congenital cyst and usually located in the midline neck below the hyoid bone. Rarely the thyroglossal cyst is associated with thyroid cancer. Although the Sistrunk procedure is often considered adequate, currently there is no clear consensus on the optimal manageme...

884 CMAJ, May 15, 2012, 184(8) © 2012 Canadian Medical Association or its licensors Gallstone disease is responsible for about 1.8 million ambulatory care visits and more than 700 000 cholecystectomies yearly in the United States. In Canada, the adjusted annual rate of elective cholecystectomy was 260.8 per 100 000 population during the period 1992–2000. Gallstone disease is the second most com...

Male-specific migration of cells from the mesonephric kidney into the embryonic gonad is required for testis formation in the mouse. It is unknown, however, whether this process is specific to the mouse embryo or whether it is a fundamental characteristic of testis formation in other vertebrates. The signalling molecule/s underlying the process are also unclear. It has previously been speculate...

We report two cases of common bile duct stone formed around a fish bone which migrated from the intestinal tract, along with their characteristic imaging findings. Two patients who had no history of previous operation were admitted because of cholangitis. Percutaneous transhepatic biliary drainage (PTBD) was performed and the cholangiogram showed filling defects with an unusually elongated shap...

Knowledge of the variant vascular anatomy of the subhepatic region is important for hepatobiliary surgeons in limiting operative complications due to unexpected bleeding. The pattern of arterial blood supply of 102 gallbladders was studied by gross dissection. The cystic artery originated from the right hepatic artery in 92.2% of cases. The rest were aberrant and originated from the proper hepa...
