Acute cholecystitis is a relatively common digestive system disease in clinical practice, often triggered by the presence of gallstones, leading to acute inflammation of the gallbladder. When an acute cholecystitis attack occurs, it typically presents as pain in the upper right abdomen, accompanied by fever, and sometimes nausea and vomiting, similar to symptoms of gastric discomfort. Additionally, if a gallstone falls and lodges in the cystic duct, or even in the common bile duct, it can cause jaundice, as indicated by the yellowing of the skin and sclera. During a physical examination, it might be possible to detect tenderness in the upper right abdomen, or even rebound tenderness. Another possible positive sign could be Murphy's sign, which are all common manifestations of acute cholecystitis.
