| 1 | Endoscopic papillary balloon dilation for diffi cult common bile duct stones:Our experience显示文摘AIM: To evaluate the eff icacy and safety of endoscopic balloon dilation(EBD) performed for common bile duct(CBD) stones.METHODS: From a computer database, we retrospectively analyzed the data relating to EBD performed in patients at the gastrointestinal unit of the Sandro Pertini Hospital of Rome(small center with low case volume) who underwent endoscopic retrograde cholangiopancreatography(ERCP) for CBD from January 1, 2010 to February 29, 2012. All patients had a proven diagnosis of CBD stones studied with echography, RMN cholangiography and, when necessary, with computed tomography of the abdomen(for example, in cases with pace-makers). Prophylactic therapies, with gabexate mesilate 24 h before the procedure and with an antibiotic(ceftriaxone 2 g) 1 h before, were administered in all patients. The duodenum was intubated with a side-viewing endoscope under deep sedation with intravenous midazolam and propofol. The patients were placed in the supine position in almost all cases. EBDof the ampulla was performed under endoscopic and f luoroscopic guidance with a balloon through the scope(Hercules, wireguided balloon, Cook Ireland Ltd. and CRE, Microvasive, Boston Scientific Co., Natick, MA, United States). RESULTS: A total of 14 patients(9 female, 5 male; mean age of 73 years; range 57-82 years) were enrolled in the study, in whom a total of 15 EBDs were performed. All patients underwent minor endoscopic sphincterotomy(ES) prior to the EBD. The size of balloon insuff lation depended on stone size and CBD dilation and this was performed until it reached 16 mm in diameter. EBD was performed under endoscopic and f luoroscopic guidance. The balloon was gradually f illed with diluted contrast agent and was maintained inf lated in position for 45 to 60 s before def lation and removal. The need for precutting the major papilla was 21.4%. In one patient(an 81-year-old), EBD was performed in a Billroth Ⅱ. Periampullary diverticula were found only in a 74-year-old female. The adverse event related to the procedures(ERCP + ES) was only an intra procedural bleeding(6.6%) that occurred after ES and was treated immediately with adrenaline sclerotherapy. No postoperative complications were reported.CONCLUSION: With the current endoscopic techniques, very few patients with choledocholithiasis require surgery. EBD is an eff icacious and safe procedure. | Maddalena Zippi Isabella De Felici Roberta Pica Giampiero Traversa Giuseppe Occhigrossi | 2013 | World Journal of Clinical Cases2013，1，1： | 4 |
