Hartmann's pouch

Hartmann’s pouch is an out-pouching of the wall of the gallbladder at the junction of the neck of the gallbladder and the cystic duct. Its identification is useful in delineating biliary anatomy when performing a cholecystectomy.

It is named after Henri Albert Hartmann who first described it.

Sometimes the term "Hartmann's pouch" is used to describe "Hartmann's procedure" which refers to a colon or rectal resection without an anastomosis in which a colostomy or ileostomy is created and the distal colon or rectum is left as a blind pouch.

Clinical significance Impaction of gallstones in the Hartmann's pouch leads to Mucocoele of Gall Bladder.
