Congenital Bilobed Gallbladder

Congenitally bilobed gallbladder with luminal bile stasis, acute on chronic cholecystitis, and two distinct luminal morphologies: A case report

“…Gallbladder is an endodermally derived organ, which develops from the hepatic diverticulum in the 4th week of intrauterine life. Rarely, congenital anomalies of the gallbladder occur where the gallbladder becomes atrophic, doubles itself, develops a septum, acquires a diverticulum, and or is completely absent [2,3]. Duplication of gallbladder is the result of splitting of the cystic primordium which typically occurs during the 5th or 6th weeks of embryogenesis.…”

“…In addition, Moores and Gregory (2007) encountered a duplex gall bladder with two separate cystic ducts associated with extrahepatic biliary disease in male cat. The duplicated gallbladder of an ox slaughtered were determined to be a bifid or bilobed being separated into two by a deep cleft while joined around the neck (Boyden, 1926;Anderson and Ross, 1958). The rarity of their occurrence might have been responsible for the scarcity of documented information on the occurrence of congenital malformations gallbladder and its clinical significance.…”

A double or bilobar gallbladder as a cause of severe complications after (laparoscopic) cholecystectomy

“…There should be a relatively high incidence of unilobar or bilobar gallbladder pathology in cases of duplication (although some authors presume the contrary [14]) such as acute and chronic cholecystitis, cholelithiasis, cholesterolosis, papilloma, carcinoma, and torsion [1,6,8,9].…”

“…There is no evidence that the anomaly itself, in the absence of disease, causes symptoms referable to biliary dysfunction [1,6]. Concomitance with other congenital anomalies has been described, such as an anomalous right hepatic artery [14].…”
