Previous cholecystectomy and choledochal sphincter spasm after morphine sedation.

摘要

PURPOSE: To describe a patient with probable choledochal sphincter spasm after preoperative morphine, and to suggest a history of cholecystectomy as a predisposing factor. CLINICAL FEATURES: A 60 yr old man for femoral-popliteal artery bypass grafting developed right upper quadrant abdominal pain after preoperative morphine and scopolamine. He had a previous cholecystectomy. His pain was relieved with naloxone. CONCLUSION: Choledochal sphincter spasm should be part of a differential diagnosis in right upper quadrant pain after sedative doses of morphine, especially if there is a previous cholecystectomy.
