Poor therapeutic response to endoscopic sphincterotomy in patients with sphincter of Oddi dysfunction having concomitant dysmotility symptoms

Background and study aims: In patients suffering from postcholecytectomy pain and elevated sphincter of Oddi (SO) basal pressure endoscopic sphincterotomy (EST) is suggested to abolish symptoms.
