title: Selective sphincteroplasty of the papilla in cases at risk due to atypical anatomy.
abstract: OBJECTIVE
  To analyze the indications, efficacy and safety of sphincteroplasty in our centre.
  
  
  METHODS
  A retrospective study of sphincteroplasty in 53 cases of papilla at high risk was performed in 2004-2006. The procedure consisted of duodenoscopy with Olympus TJF 145 Videoduodenoscope, approach to the biliary tract using a catheter with a guidewire, and dilatation of the papilla with a dilatation balloon catheter using a syringe with a manometer for control of the filling pressure.
  
  
  RESULTS
  The indications included intradiverticular papilla in 26 patients (49%), stenosis of a previous sphincterotomy in 19 patients (35.8%), small size of the papilla in 4 patients (7.5%), Billroth II gastrectomy in 3 patients (5.6%), and coagulopathy in one patient (1.9%). The efficacy was 97.8%, with all the calculi extracted from the common bile duct in 84.4% of the patients, even though 21 of the patients (39.6%) had calculi with a diameter equal to or greater than 10 mm. Seven patients (13.2%) presented complications: haemorrhage in 1 patient (1.9%) and mild pancreatitis in 6 patients (11.3%). The mean hospital stay in case of complications was of 3 +/- 0.63 d.
  
  
  CONCLUSIONS
  Sphincteroplasty is highly effective, with a complication rate similar to that of sphincterotomy, furthermore, the complications are of low clinical importance. The use of the 10 mm balloon makes it possible to extract calculi with a diameter of over 15 mm and to extract more than 3 calculi without increasing the rate of complications and reduces the need to resort to lithotripsy or rescue sphincterotomy.
