Delayed Post-cholecystectomy Gallbladder Fossa Abscess Due to Citrobacter freundii.

While laparoscopic cholecystectomy has become the treatment of choice for cholecystitis, complications such as abscess development can result even years after the intervention. We present a case of a patient with a remote history of laparoscopic cholecystectomy now diagnosed with gallbladder fossa abscess infected with Citrobacter freundii, a low-virulence pathogen typically seen in iatrogenic urinary tract infections. Subsequent conjoint percutaneous drainage and long-term antibiotics resulted in both clinical and radiological improvement for the patient. Therefore, in the absence of recent events or risk factors for developing an abdominal wall abscess, a previous remote history of surgical intervention needs to be considered for the possible etiology, especially those with low incidences and long latency periods such as Citrobacter.
