described technique allowed successful cannulation and safe sphincterotomy in our Billroth II patient with the use of a conventional side-viewing duodenoscope and standard sphincterotome. To our knowledge, this approach has not been previously reported. The proposed maneuver represents an alternative technique for papillary cannulation and sphincterotomy in selected patients with Billroth II anatomy who have appropriate length and sufficient width of the afferent limb to allow safe retroflexion of the duodenoscope. The authors declare no conflicts of interest for this article.
