Background:
Acute gangrenous cholecystitis (AGC) is a medical emergency that carries high morbidity. The objective of this study is to define risk factors for this disease.
Methods:
A retrospective review of patients who underwent cholecystectomy while admitted to the Acute Care Surgery Service from January 2009 to April 2014 was performed. Specimen reports were evaluated to identify patients with AGC and cholecystitis without necrosis (CN). Preoperative factors as well as outcomes were compared between the groups.
Results:
A total of 483 patents underwent cholecystectomy. Four hundred fifty-nine patients were found to have CN and 24 patients were found to have AGC. Pre-existent factors such as diabetes, coronary artery disease, and systemic inflammatory response syndrome predicted AGC on a logistic regression. Patients with AGS were also more commonly older, male, and had a higher preoperative bilirubin. Mortality was significantly higher in patients with AGC (12.5% vs .9%, P = .003).
Conclusions:
AGC carries an increased mortality rate compared with CN. Older patients with diabetes, coronary artery disease, and elevated bilirubin should be suspected of having AGC.

Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
