Gallbladder triplication

Last revised by Yuranga Weerakkody on 15 May 2017

Gallbladder triplication is an extremely rare anomaly. There are three types of gallbladder triplication are described according to the number of cystic duct and their insertion:

  1. Three gallbladders and three cystic ducts which unite to form a common cystic duct before joining the common bile duct (CBD).
  2. Two cystic ducts join to form a common duct before joining the CBD and remaining cystic duct enters the CBD separately.
  3. All three cystic ducts join the CBD separately.

Embryologically, accessory gallbladders result from persistence of rudimentary bile duct buds. As in gallbladder duplication, a higher incidence of pathology may occur in gallbladder triplication.
