Endoscopic sphincter of Oddi manometry in patients with postcholecystectomy syndrome and persisting biliary pain despite previous endoscopic sphincterotomy

Introduction: Persistent pain after endoscopic sphincterotomy (EST) is reported in 5–10% of patients with sphincter of Oddi dysfunction (SOD), about 1–5 years after papillotomy, is believed to be due to incomplete papillotomy or Vater papilla restenosis. In both pathogenic condition residual SO pressure can be demonstrated by endoscopic SO manometry (ESOM). The aim of our present study was to prospectively measure SO residual pressure with ESOM in those SOD patients (pts), who had returned because of persistent or recurrent pain following EST. Methods: 11 consecutive, female, SOD pts with persistent or recurrent…
