Introduction: The importance of gall bladder motility and of how this can be modified by endoscopic, therapeutic procedures indicates the momentous role that it has in the genesis of gall bladder stones. Previous studies have determined that endoscopic biliary sphincterotomy diminishes the gall bladder volume in fast and increases the capacity of gall bladder contraction, diminishing the emptying volume of the gall bladder significantly,as well as residual volume and increasing the ejection fraction, after endoscopic sphincterotomy. Objective: To determine the effect of endocopic sphincterotomy on gall bladder motility in patients with choledocholithiasis, hospitalized in the Gastroenterology Service of the University Hospital of Caracas in the period understood among May 2006 - January 2007. Methods: descriptive ,prospective study of a selected sample of 16 patients with choledocholithiasis to whom was determined gall bladder volume in fast, post prandial at 18, 24 and 30 min, residual volume and ejection fraction; by means of abdominal ultrasonography, before and after the endoscopic sphincterotomy. Results: by means of the test of Wilcoxon it was demonstrated that after the sphincterotomy there was a statistically significant reduction (P <0.05) of the gall bladder volumes in fast, residual and post prandial at the 18, 24 min and an increase in the EF of 14.4%. with a P = 0.014. According to sex and age it was found that the feminine sex was the most frequent with 13 patients (81.25%), and the masculine sex with 3 patients (18.75%) with an average age 41.38 years SD 11.4 years. Conclusions: Endoscopic sphincterotomy improves gall bladder motility reflected in a decrease of volume in fast, and residual volume and in an increase of the ejection fraction,being its use recommended in those cases an where indication exists. The use of the abdominal ultrasound is also recommended as a method for the study of the gall bladder motility.
