I read with interest an article published in Surgical Rounds. It is a case report discussing disturbed liver function tests in the absence of bile duct injury. WHY check postoperative liver functions at all in a patient that undergoes an uneventful laparoscopic cholecystectomy and had normal liver function tests preop? The patient in your case report had prolonged hospitalization and intrumentation with ERCP (normal) while she was asymptomatic!! Did your resident get away from you and order those post op LFT's for his own curiosity? This reminds me of the story about the dogs that chase the school bus. What are they going to do when they catch it?
