Cholecystitis is an inflammation of the gallbladder wall.
The inflammatory process, once initiated, generates changes at both microscopic and macroscopic levels, evolving from simple congestion, through a suppuration phase, to gangrene to perforation.
The whole thing turns out to be a consequence of the inflammatory response.
The process begins with cellular infiltration, fluid extravasation, and physiologic consequences that may be spontaneous healing or abscess formation and the occurrence of complications such as sepsis, perforation, fistula, and the possible formation of a platelet due to the involvement of structures located in the vicinity of the gallbladder, from whose wall germs are filtered.
