[Postoperative jaundice]

The numerous causes and mechanisms of postoperative icterus are discussed. Reference is made to the difficulty of diagnosing cases needing further surgical treatment. Stress is laid on the importance of correct operative techniques and radiological and instrumental methods (endocholedochic endoscopy according to Battezzati) to reduce the incidence of residual calculosis that weighs upon operations for calculous cholecystitis.
