Description
Summary:AIM:To evaluate short-type-single-balloon enteroscope(SBE) with passive-bending,high-force transmission functions for endoscopic retrograde cholangiopancreatography(ERCP) in patients with Roux-en-Y anastomosis.METHODS:Short-type SBE with this technology(SIF-Y0004-V01; working length,1520 mm; channel diameter,3.2 mm) was used to perform 50 ERCP procedures in 37 patients with Roux-en-Y anastomosis.The rate of reaching the blind end,time required to reach the blind end,diagnostic and therapeutic success rates,and procedure time and complications were studied retrospectively and compared with the results of 34 sessions of ERCP performed using a short-type SBE without this technology(SIF-Y0004; working length,1520 mm; channel diameter,3.2 mm) in 25 patients.RESULTS:The rate of reaching the blind end was 90% with SIF-Y0004-V01 and 91% with SIF-Y0004(P = 0.59).The median time required to reach the papilla was significantly shorter with SIF-Y0004-V01 than with SIF-Y0004(16 min vs 24 min,P = 0.04).The diagnostic success rate was 93% with SIFY0004-V01 and 84% with SIF-Y0004(P = 0.17).The therapeutic success rate was 95% with SIF-Y0004-V01 and 96% with SIF-Y0004(P = 0.68).The median procedure time was 40 min with SIF-Y0004-V01 and 36 min with SIF-Y0004(P = 0.50).The incidence of hyperamylasemia was 6.0% in the SIF-Y0004-V01 group and 14.7% in the SIF-Y0004 group(P = 0.723).The incidence of pancreatitis was 0% in the SIFY0004-V01 group and 5.9% in the SIF-Y0004 group(P > 0.999).The incidence of gastrointestinal perforation was 2.0%(1/50) in the SIF-Y0004-V01 group and 2.9%(1/34) in the SIF-Y0004 group(P > 0.999).CONCLUSION:SIF-Y0004-V01 is useful for ERCP inpatients with Roux-en-Y anastomosis and may reduce the time required to reach the blind end.
