Spontaneous cholecystocutaneous fistula in a case of chronic colculous cholecystitis--a case report.

Chronic calculous cholecystitis is quite a common disease entity today. However, advances in diagnostic imaging and use of broad-spectrum antibiotics have facilitated its early detection and treatment. Hence complications of untreated calculous cholecystitis have shown a steady decline. Spontaneous cholecystocutaneous fistula is one such rare complication. A 45-year-old female presented with acute onset of pain and swelling in the right hypochondrium. She had leucocytosis. The swelling ruptured spontaneously and 200 ml frank yellow pus along with multiple stones were expelled from the site. Completion drainage was done. A fistulogram confirmed the diagnosis of a cholecystocutaneous fistula. The patient underwent open cholecystectomy and excision of the fistulous tract.
