Background and Aim A limited number of endoscopic retrograde cholangiopancreatography ( ERCP ) accessories are compatible with the conventional single‐balloon enteroscope ( SBE ) because of the latter's dimensions. The aim of the present study was to assess the utility of a prototype SBE that has a shorter working length and a wider channel than the conventional SBE . Methods ERCP procedures carried out between J anuary 2012 and J uly 2013 using the short SBE prototype were reconstructions such as Billroth II ( B ‐ II ), post‐gastrectomy with R oux‐en‐ Y ( RY ‐ G ), and post‐choledochojejunostomy with R oux‐en‐ Y ( RY‐CJ ). We retrospectively analyzed the rate of reaching the blind end of the intestine, the diagnostic success rate, the interventional success rate, and the frequency of related complications.Results Twenty‐seven ERCP procedures on 18 patients analyzed comprised two B ‐ II , 15 RY ‐ G , and 10 RY‐CJ reconstructions. With a mean procedure time of 56 min (range 40–150 min), the rate of reaching the blind end, the diagnostic success rate, and the interventional success rate were 24/27 (89%), 20/27 (74%), and 19/27 (70%), respectively. There were no major ERCP ‐related complications in any patient. Conclusions The prototype short‐type SBE appears safe and effective for use in ERCP , and is compatible with conventional endoscopy accessories.
