Abstract:
Gallbladder perforation is an uncommon but morbid complication of acute cholecystitis with mural ischemia and necrosis. The most common site of perforation is the fundus because of limited blood supply in this region. The Niemeier classification proposed in 1934 remains the criterion standard in grading gallbladder perforation; type 1 is acute with free perforation into the peritoneal cavity, type 2 is subacute with pericholecystic abscess, and type 3 is chronic with cholecystoenteric fistula. We report a challenging case of type 1 gallbladder perforation due to acute acalculous cholecystitis.

Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
