RESUMO
Local experience on the combined technique of endoscopic sphincterotomy followed by endo: scopic balloon dilation is scarce. This study clarified whether this crombined technique will offer any advantages, with respect to therapeutic outcome and complications rate, as compared with endoscopic sphincterotomy (ES) and endoscopic balloon dilatation (EBD) alone for the extraction of large and/or multiple common bile duct stones. For a total of 76 patients, extraction of large and/or multiple common bile duct (CBD) stones during endoscopic retrograde cholangiopancreatography was performed. According to the used technique, they were categorized into 3 groups; Endoscopic sphincterotomy, endoscopic balloon dilatation or combined technique. The success rate of complete stone removal and the incidence of procedure-related complications were compared among the three groups. Success rate after one session was recorded to be comparable among the three groups. Relative Risk Ratio assessment of success rate after single session among the three groups showed no statistically significant difference. Regarding bleeding, only 3 (10%) cases were recorded in the ES group with no cases in the, other 2 groups. No significant difference was noted among the three groups regarding other complication. The combined technique of ES followed by EBD is an effective and safe technique enables extraction of multiple and/or relatively large stones. It could be a reasonable alternative option when standard techniques are inadequate to remove bile duct stones.
