Efficacy of daily abdominal self-massage for the prevention of recurrent common bile duct stones after endoscopic biliary sphincterotomy.

Recurrent common bile duct stones (CBDS) can occur after endoscopic biliary sphincterotomy (EST). Bile flow through the papilla of Vater could be improved by means of abdominal massage. We report the results of self-abdominal massage in four patients who had previously undergone cholecystectomy and experienced multiple CBDS recurrences after EST.
