[Aerobilia: a rare consequence of anaerobic acute cholecystitis: a case report]

Acute acalculous cholecystitis is rare in non critically ill or postoperative patients. We report a case of acute acalculous cholecystitis with secondary bile infection with Clostridium perfringens. Ultrasound and tomodensitometry revealed diffuse aerobilia. The germ in this case report is atypical and contrasts with the very discrete clinical findings. Aerobilia, secondary to the development of bacteria in the biliary tract falsely suggested a bilio-digestive fistula. Treatment included a simple cholecystectomy associated with 7 days of antibiotherapy.

[Colonic actinomycosis. Clinical, endoscopic and histological aspects in one patient]

Colonic location of actinomycosis must be distinguished from infected colonic carcinoma and other colonic inflammatory pseudotumors. The diagnosis is often made by histological examination of the tumor. Initial treatment consists in surgery, followed by an antibiotic treatment. We report the case of a 32-year old woman with a right colonic actinomycosis.
