Abdominal actinomycosis after laparoscopic cholecystectomy: an uncommon presentation of an uncommon problem.

Actinomycosis is a rare bacterial infection with a broad clinical presentation that is seldom reported after elective cholecystectomy. We present an as-of-yet unreported case of actinomycosis in an 81-year-old gentleman who was found to have right-sided peritonitis and small bowel obstruction 11 months after elective laparoscopic cholecystectomy. A complex loculated lesion was found on laparotomy with a protracted course of antibiotics being needed for treatment. The rarity of this condition will mean it remains a surprise diagnosis to many clinicians. However, it is important that clinicians maintain some index of suspicion to prevent unnecessary surgery and are aware of the protracted course of antibiotics that is needed for successful treatment.
