Endoscopic retrograde cholangiopancreatography (ERCP) is a difficult procedure to perform on patients who have undergone a Billroth II gastrectomy, Whipple's operation or Roux-en-Y gastrobypass surgery. Our study was designed to evaluate the clinical usefulness of cap-assisted ERCP for beginner endoscopists in cases of surgically altered anatomy.
From April 2008 to March 2010, 16 patients with biliary diseases and who had previously undergone abdominal surgery such as Billroth II gastrectomy or Roux-en-Y operation were analyzed. A single endoscopist performed all the procedures using a cap-assisted gastroscope, after ERCP training.
Cap-assisted ERCP was attempted in 24 sessions of 16 patients. Afferent loop intubation and selective bile duct cannulation was successfully achieved in 19 sessions (79.1%). Among the patients who had undergone a Billroth II gastrectomy, 19 out of 20 sessions were successfully conducted. Only 4 patients who had undergone a previous Roux-en-Y operation failed afferent loop intubation. Duodenal free wall perforation developed in one case. There were no cases of mortality.
Therapeutic cap-assisted ERCP was useful in patients who had previously undergone a Billroth II gastrectomy and this may be helpful for inexperienced endoscopists. (Korean J Gastrointest Endosc 2010;41:344-349)
