Laparoscopy and acalculous cholecystitis.

Acalculous cholecystitis is probably more common than the medical literature would suggest. This paper reviews a series of 13 patients who presented with symptoms of cholecystitis and who had normal ultrasound or cholecystogram examinations. Eleven patients underwent cholecystectomy and all had their symptoms ameliorated or cured. Laparoscopy is suggested as an early diagnostic procedure in these patients, followed by cholecystectomy if there is objective laparoscopic evidence of cholecystitis.
