EST의약 10% 는해부학적변이, 유두협착등의이유로당김형괄약근절개기로시술이불가능하다. 이러한경우침형괄약근절개기 (needle type papillotome) 가이용되었으나심각한합병증의가능성을가지고있고시술에많은경험을요한다. 특히 Billroth II 위절제술을시행받은환자에서는특별히고안된역방향절개도 (reverse papillotome) 나 S자형절개도 (sigmoid papillotome), 또는침형절개도 (precut biliary needle-knife papillotome) 를이용하여 5 시 6시방향을절개해왔으며, 최근유도철선을이용한유두부절개도 (wire-guided billroth II papillotome) 는도관삽입의성공률을높이는것으로보고되었다. 10,11 이후 athuna 등 12 이유두괄약근절개술이기술적으로어려운경우유두부풍선확장술이담관내결석제거를위한한방법으로제시하였으며, Zanon 등 13 은경피경간유두절개술의효용성을제한된증례에서입증하였으나경구경유두경로를통한제거가불가능하고수술에따른위험도가높은환자들에게서제한적으로사용될것으로보고하였다.

Billroth II 위절제술을시행받은환자에서는 EST와관련된천공을비롯한합병증이통상적인경우보다매우높게보고되고있어, 17,18 향후다른유두절개방법과비교하여성공률, 합병증에대한대규모연구가필요할것으로생각한다. 본증례들에서는 Billroth II 위절제술을시행받은환자에서 ERCP 및 EST는회전절개도를이용하여성공적으로시행할수있었으며추후많은경험축적및비교연구가필요하다. ABSTRACT Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) are the mainstays of the diagnosis and treatment of variable hepatobiliary and pancreatic diseases. The success rate of ERCP and EST in patients who have undergone a Billroth II gastrectomy is lower than in patients with a normal anatomy. Because the view of the ampulla is rotated 180 o in patients with Billroth II, several methods (ex, precut biliary needle-knife papillotome or wire-guided billroth II papillotome) have been used for endoscopic sphincterotomy instead of a pull-type papillotome. Using the recently devised pull-type and rotatable papillotome (Autotome R ), we performed successful ERCP and EST in 2 patients with a Billroth II gastrectomy without complications.
