Introduction: Benign papillary stenosis has different etiologies. It present as acute or recurrent biliar pain, alteration in cholestatic profi le and jaundice. Endoscopic Cholangiography is the gold standard in the diagnoses: extra hepatic biliar tract dilatation and intrapapillary narrowing of common bile duct in “pen tip”. Endoscopic sphincterotomy has a success rate from 99 to 100%. Methods: We included patients from January 2004 to February 2012 with biliary tract dilatation, alteration in cholestasis profi le and biliary pain. Results: From 1128 Retrograde cholangiography endoscopic, 96 (6.11%) were benign papillary stenosis. 64 (66.7%) female, 45 (46.9%) in situ gall bladder and 19 (19.8%) cholecistectomized. Alteration in cholestasis profi le in 78 patients (81.3%). Endoscopic fi ndings: torn sphincter 54 (56.3%). Biliary tract access in all cases, 80 (83.3%) arch sphincterotomo. Association with choledocholithiasis 33 (34.4%). The complications were mild pancreatitis and hemorrhage (5.2%). Conclusions: Benign papillary stenosis incidence was 6.11%. Torn sphincter makes us suppose a traumatic etiology by the passage of the stones and hypertrophy of the muscle elements in sphincter of Oddi. Endoscopic sphincterotomy is a safe and effective technique to resolve the benign papillary stenosis.
