Two unusual cases of postcholecystectomy pain

I report on two patients who were initially diagnosed with sphincter of Oddi dysfunction (S.O.D.) because of postcholecystectomy pain in the right upper quadrant; both had other causes of pain. One patient had an aberrant hepatic duct that drained into a remnant of the cystic duct resulting in formation of stones. The second patient had adhesions of the stomach to the liver with the ligamentum teres bowing across the antrum. Gastroenterologists and endoscopic surgeons should be aware of causes of postcholecystectomy pain that are unrelated to sphincter of Oddi dysfunction.
