Standard laparoscopic cholecystectomy for malposition of the gallbladder caused by right-sided ligamentum teres
A 31-year-old female patient was admitted to the surgical clinic because of recurrent right upper quadrant pain during the last 2 months. Clinical examination and laboratory analysis were normal. Stones in the GB were detected on abdominal ultrasonography. She was taken into the operating theatre with a diagnosis of cholelithiasis. At exploration, the GB was absent from its normal location, and it was found just left to LT []. It had edematous and hydropic appearance with an impaction of a calculus at the neck. With the standard localization of ports and a LT lift, it was possible to perform cholecystectomy via laparoscopically in a retrograde manner. During the operation, it was found that there was a short and wide cystic duct joining to the common bile duct on the right side, and the cystic artery with anterior and posterior branches originating normally from the right hepatic artery. She was discharged uneventfully at the first postoperative day. Pathologic examination showed chronic calculous cholecystitis.\nMagnetic resonance cholangiopancreatography and angiography were performed to understand the biliary and portal venous system anomalies. This showed the first branch of the portal vein (PV) running to the right posterior segment, and then formation of the main trunk of the left and right anterior PVs []. The latter vein formed saccularly dilated umbilical portion of PV and finally joined to LT [].
