A bilobed Gallbladder (Vesica Fellea Divisa) in Cattle Slaughtered at Jimma Municipal Abattoir, West Oromiya, Ethiopia

“…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.…”

“…The bilobed gallbladder has been encountered in higher vertebrates such as cats with an incidence rate of 10% (Martinoli et al, 1993). Domestic species other than cats have a lower incidence of gallbladder anomalies related to their anatomical differences (Boyden, 1926).…”

“…They arise from abnormalities in embryogenesis during the fifth and sixth weeks of gestation Causey et al, (2010) and the described malformations vary anatomically in location (site), number, size, shape and heteropias Martinoli et al, (1993); Patel et al, (2008). Boyden (1926), Gross (1936) and Harlaftis et al, (1977) have proposed various types of classifications of congenital malformations of gallbladder based on its anatomic or embryologic development. In general, malformations of the gallbladder are categorized as divisa (partially divided and bilobed or bifid) accounting for most of anomalies, duplex (double) that are responsible for 10% of the abnormalities or multiplex (multiple) (Moores and Gregory, 2007).…”

“…5 There are newer classifications such as the Harlaftis classification and its modifications. 1,6 A, B and C are partial duplications and classified into septate, fundic and body types.…”

Duplicated Gallbladder

“…1 We herein report a successfully diagnosed case of duplicated gallbladder using drip infusion cholecystocholangiography-computed tomography (DIC-CT).…”
