Duplication of gallbladder: A rare congenital malformation

Unusual variant of choledochal cyst in a child: A case report, in Tertiary Specialized Hospital, Ethiopia

“…Type II CC can also be a differential for gall bladder duplication which is a rare variant of GB anatomical anomalies with a frequency of 1:3000–4000 [ [8] , [9] , [10] ]. As described in Fig.…”

“…As described in Fig. 5 GB duplication can have a common cystic duct and arterial supply if it is the splitted group or it can originate separately from the CHD, CBD or one of the hepatic duct with its own vascular supply arising from the hepatic artery or the cystic artery [ 8 , 9 ]. On pathologic examination duplication of a GB has a muscular wall with an epithelial linings while CCs have a firm, fibrotic wall and contain variable quantities of bile.…”

“…In our case the pedicle of the cyst attaches to the posterior wall of common hepatic duct with 0.2 cm diameter and 0.5 cm length. In addition to not having a proper muscular wall and deficient epithelial lining it also has no its own vascular supply which makes it against GB duplication [ 8 , 10 ].…”

“…Differential diagnosis must be considered before surgery including gallbladder duplication, gallbladder diverticula, gallbladder fold, Phrygian cap, pericholecystic fluid, focal adenomyomatosis, and intraperitoneal fibrous bands and should be checked on the preoperative investigations and also during exploration [ 12 ]. And the best option of management of type II choledochal cyst is complete excision [ 4 , 8 ].…”
