Endoscopic sphincterotomy for suspected choledocholithiasis in patients with and without stones.
OBJECTIVE
To characterize a subgroup of patients treated with endoscopic sphincterotomy (ES) for a suspected common bile duct lithiasis (CBDL) that was not confirmed and to compare it with the subgroup with confirmed CBDL.


RESULTS
Over 18 months, ES was successful in 245 consecutive patients (age 23-97, mean 75 yr, SE 17 yr) with suspected CBDL; 159 patients had CBDL (group 1), and 86 did not (group 2), as confirmed by CBD exploration. Fifty-nine percent of the patients in group 1 and 76.7% of the patients in group 2 had gallbladder in situ. Both groups were different for age (p < 0.001), prevalence of chronic alcoholism (p < 0.001), gallbladder in situ (p < 0.01), and gallbladder stones (p < 0.05). Patients from group 1 had two or more presenting symptoms suggestive of CBDL more often than patients from group 2 (p < 0.05), and pancreatitis was a more frequent presenting manifestation in group 2 (p < 0.0001). Overall morbidity and mortality were not different between groups, but acute cholecystitis developed in six patients from group 2 and in one patient from group 1 (p < 0.01). In a univariate analysis, only elevated alkaline phosphatase and a dilated common bile duct were positively discriminant for the diagnosis of CBDL; chronic alcoholism was negatively discriminant for the diagnosis of CBDL. In a multivariate analysis, only chronic alcoholism and a dilated bile duct were found to be independently discriminant.


CONCLUSIONS
The risk of ES-related complications in the group without CBDL suggests that the selection of patients should be improved by a better use of preoperative criteria.
