A randomized trial of endoscopic biliary sphincterotomy using pure-cut versus combined cut and coagulation waveforms.

Background & Aims: Endoscopic biliary sphincterotomy has complication rates of 5%-12%. The output from the electrosurgical generator may influence the degree of coagulation and the rapidity of the incision, and thus rates of pancreatitis, hemorrhage, and perforation. Some modern generators incorporate feedback control to standardize output and automate the alternating cut and coagulation modes.
