REGO, Ana Catarina et al. Papillary Large-Balloon Dilation Preceded by Sphincterotomy for Removal of Bile Ducts Stones: One Year Experience. J Port Gastrenterol. [online]. 2011, vol.18, n.6, pp.279-284. ISSN 0872-8178.

INTRODUCTION: Papillary balloon dilation with TTS-CRE balloon (through the scope-controlled radial expansion) in association with sphincterotomy (EST) has been used for removal of large bile duct stones. OBJECTIVES: We present the 12 month experience of our Department wherein we performed a EST followed by papillary balloon dilation for removal of bile duct stones. Efficacy, need for mechanical lithotripsy and occurrence of complications were evaluated. METHODS: Papillary balloon dilation preceded by EST was performed in 25 patients from October 2009 to September 2010. Patients included in the present study had bile duct stones with a diameter greater than or equal to 10mm detected on cholangiogram obtained during endoscopic retrograde cho­langiopancreatography (ERCP). We used TTS-CRE balloons with 12 to 20mm. RESULTS: Of the 25 patients, 12 (48%) were female. Average age was 73 years and 65% of patients had two or more stones. The average size of the stones was 15mm. Six patients had residual bile duct stones with prior EST. In 100% of cases complete removal of the bile duct stones was achieved in a single session. There was no need for mechanical lithotripsy. There were no complications. CONCLUSION: The combination of the two methods proved effective, fast and safe for removal of large bile duct stones
