A floating gallbladder
hangs on a mesentery which makes it liable to undergo torsion.
A long mesentery or a
very short/absent mesentery allow mobility of the gallbladder along
its vertical axis.
Torsion, or volvulus, of
the gallbladder occurs when it twists axially, with the subsequent
occlusion of bile and/or blood flow. It is rare and is difficult to
diagnose preoperatively. It was first described by Wendel in 1898
(A. V. Wendel, “Case of floating
gall-bladder and kidney complicated by cholelithiasis with perforation
of the gallbladder,” Annals of Surgery, vol. 27, no. 2, pp. 199–202,
This rare condition
usually occurs in the elderly patients.
Early diagnosis of
gallbladder torsion is important to avoid the complication of
perforation and bilious peritonitis.
