Aim: to aware the presence of hepatic anomaly with accessory hepatic lobe (AHL) of liver during surgery of symptomatic gallstones.
Accessory hepatic lobe of liver (AHL) either in continuity with the proper liver parenchyma or embedded in the tissue not connected with the liver as ectopic hepatic lobe (EHL) has been labeled in rare category. In Saudi Arab two consequent cases in patients aged by 21 and 38 years presented with cholecystitis and cholelithiasis reported in the same hospital in 6 months duration. One was seen during laparoscopic cholecystectomy and another confirmed on histopathological examination.
Above study showed quiescent AHL therefore left untreated.
EHL which was found on the surface of gall bladder was excised along with stone containing gall bladder during cholecystectomy.
AHL although rare but not infrequent and is usually diagnosed intraoperatively. Its possible existence either in continuity with the liver or as an ectopic hepatic tissue during any kind of surgery (abdominal, thoracic) must be in knowledge because if it goes into serious complications, will change the whole treatment strategy and needs its concomitant resection.
Key words: Accessory hepatic lobe, ectopic liver tissue, cholelithiasis, cholecystitis, laparoscopic surgery
