title: Relation of size and number of common duct calculi to success of sphincterotomy and stone extraction.
abstract: Endoscopic sphincterotomy (ES) for common bile duct calculi (CBDC) was performed on 210 patients, and 190 of these were available for follow-up. One hundred seventy-three patients (91%) were successfully treated with ES alone, whereas 17 patients required operation. Stone size was of importance to attain complete clearance of CBDC as larger stones (greater than 1 cm) were significantly more difficult to extract endoscopically than smaller stones (p less than 0.01). A comparison between patients with one CBDC and those with two or more show a statistically significant difference in that the former group is easier to treat successfully (p less than 0.001).
