The presence of large stones, >2.5 cm in diameter, within the gallbladder are thought to predispose to fistula formation by gradual erosion through the gallbladder fundus. [1] Once a fistula has formed, a stone may travel from the gallbladder into the bowel and become lodged almost anywhere along the gastrointestinal tract .
Generally, if it is a part of the digestive tract that is free to move, it is covered by serosa, and if it is relatively rigidly fixed, it is covered by adventitia. The connective tissue of the gallbladder is covered by adventitia where the gallbladder bounds the liver, but by serosa for the rest of its surface.
The gallbladder has a capacity of about 50 millilitres (1.8 imperial fluid ounces). [2] The gallbladder is shaped like a pear, with its tip opening into the cystic duct. [4] The gallbladder is divided into three sections: the fundus, body, and neck. The fundus is the rounded base, angled so that it faces the abdominal wall.
For example, the serosa of the uterus is called the perimetrium. Schematic diagram of an organ invaginating into a serous cavity The pericardial cavity (surrounding the heart ), pleural cavity (surrounding the lungs ) and peritoneal cavity (surrounding most organs of the abdomen ) are the three serous cavities within the human body.
The outermost layer of the gastrointestinal wall consists of several layers of connective tissue and is either of serosa (below the diaphragm) or adventitia above the diaphragm. [4] [1] [5] Regions of the gastrointestinal tract within the peritoneum (called Intraperitoneal) are covered with serosa. This structure consists of connective tissue ...
Impacted gallstone in the cystic duct is obstructing the common hepatic duct. Mirizzi's syndrome is a rare complication in which a gallstone becomes impacted in the cystic duct or neck of the gallbladder causing compression of the common hepatic duct, resulting in obstruction and jaundice.

Once tissue has died, the gallbladder is at greatly increased risk of rupture (perforation), which can cause sharp pain. Rupture can also occur in cases of chronic cholecystitis. [13] Rupture is a rare but serious complication that leads to abscess formation or peritonitis. [14] Massive rupture of the gallbladder has a mortality rate of 30%. [13]
