Cholelithiasis and acute cholecystitis

Abstract

Although much is still to be learned about the pathogenesis of cholelithiasis, recent investigations have greatly advanced our knowledge regarding the mechanisms of cholesterol supersaturation and nucleation. Laparoscopic cholecystectomy has lessened the usual peri-operative morbidity of cholecystectomy, but is associated with a higher bile duct injury rate. Acute cholecystitis, the commonest complication of cholelithiasis, is a chemical inflammation usually requiring cystic duct obstruction and supersaturated bile. The treatment of this condition in the laparoscopic era is controversial. Early operation may lessen hospital stay but an increased risk of biliary injury has been reported.
