Unusual Abdominal Wall Abscess Post-Laparoscopic Cholecystectomy

Cholecystectomy is the most commonly performed operation worldwide nowadays. Laparoscopic cholecystectomy (LC) is the gold  standard treatment of gallstones. We present a case of an 81-year-old male with a 3-months’ history of loss of appetite and weight with no associated symptoms. The patient had undergone an LC for symptomatic cholelithiasis 1 year previously, with an uneventful recovery. The clinical examination was essentially normal. A computed tomography (CT) of the abdomen and pelvis showed thickening of the right  perihepatic peritoneum measuring 15 × 15 × 3.5 cm, suggestive of chronic granulomatous lesion or atypical mesothelioma. We performed a diagnostic laparoscopy and found the lesion to be an abdominal wall abscess. The abscess cavity was deroofed, the pus was drained and a thorough wash out given. Surprisingly no stones or any foreign body were found in the cavity. Histology of the abscess wall showed non-specific inflammation. We report this case as a post-LC abdominal wall abscess with two peculiar features – (a) no systemic or local  symptoms, and (b) no association with spilt gallstones or other foreign bodies like sutures.
