The Role of Sphincterotomy in The Management of Common Bile Duct Stones

Neoptolemos JP, Shqw DE, Cart-Locke DL (1989) A Multivariate Analysis of Preoperative Risk Factors in Patients with Common Bile Duct Stones Implications for Treatment. Annals of Surgery 209: 157-161. A multivariate analysis of 30 preoperative risk factors was undertaken in 248 patients who underwent surgery alone for common bile duct (CBD) stones and in 190 patients who had endoscopic sphincterotomy (ES), 77 of whom subsequently also had surgery. Independently significant risk factors in those undergoing surgery were the serum bilirubin level, the use of preoperatives ES, and the presence of medical risk factors; in patients undergoing ES, only the serum bilirubin and albumin, but not medical risk factors, were of independent significance. The major implications of this study are, first, that high-risk patients should be treated by ES without subsequent surgery, and second, that "fit patients should be treated by surgery alone without routine preoperative ES.
