Figure 4. Endoscopic naso-biliary and naso-pancreatic drainage (ENBPD) in a case where complete closure was impossible: (A) ESD completed for lesion located on the oral side of the main papilla; (B) complete closure was impossible because the main papilla was too close to the mucosal defect; and (C) ENBPD tubes were inserted and the post-procedural clinical course was uneventful.
