    Abstract:
    BACKGROUND: Selective cannulation in patients with a Billroth II gastrectomy is still challenging. OBJECTIVE: To evaluate the usefulness of a multibending, forward-viewing endoscope (M-scope) for selective cannulation during diagnostic or therapeutic ERCP in patients with a Billroth II gastrectomy. DESIGN: Case series. SETTING: Tertiary center. PATIENTS: Fourteen patients having biliary disease with a Billroth II gastrectomy in whom selective cannulation failed when using a conventional forward-viewing endoscope. INTERVENTIONS: In all cases, we attempted selective biliary cannulation for ERCP with a single-bending, forward-viewing endoscope for 10 minutes. After failure with the conventional endoscope, we retried selective cannulation with the M-scope for 10 minutes. After cannulation, the diagnostic or therapeutic endoscopic procedures were performed. MAIN OUTCOME MEASUREMENTS: We assessed the success rate of selective cannulation, the possibility of therapeutic approaches, and procedure-related complications. RESULTS: In all cases, we successfully reached the ampulla of Vater with the M-scope. The overall success rate of selective cannulation with the M-scope was 92.9% (13/14). One patient developed mild pancreatitis. Therapeutic procedures such as sphincterotomy, balloon dilatation, stone removal, and biliary drainage were all possible. LIMITATIONS: Small number of patients; uncontrolled, single-center study. CONCLUSIONS: The M-scope seems to be helpful for selective cannulation during ERCP in patients with a Billroth II gastrectomy. All diagnostic and therapeutic procedures were possible through the M-scope.
