Abscess formation due to dropped gallstone after laparoscopic cholecystectomy

Achromobacter xylosoxidans Subdiaphragmatic Collection as a Result of a Dropped Stone During Laparoscopic Cholecystectomy

After a cholecystectomy, dropped stones can serve as a nidus for abscess formation. Intrabdominal abscesses tend to cause irritation and inflammation of the peritoneum and are thus rarely asymptomatic. This report discusses a 38-year-old female complaining of a recurrent right upper quadrant pain that led to multiple hospital admissions. Her surgical history was significant for cholecystectomy six years back complicated by a retroperitoneal abscess which was drained twice. A computed tomography (CT) scan was done, and she was diagnosed with a subdiaphragmatic collection as a result of a dropped stone.
