【 要旨 】 interventional EUSは診断のみならず治療分野まで,その適応が拡大している.従来,膵管へのアプローチはERCPが中心であったが,膵管や術後吻合部の高度の狭窄,結石の存在,などにより,ERCP手技ではアプローチが困難な症例も存在する.このような症例に対し,EUSを用いた膵管ドレナージ法(EUS‒PD)が新たなアプローチ法として報告されている.EUS‒PDは,EUS‒guided drainage technique(drainage法)とEUS‒guided rendezvous法(rendezvous法)に大別され,さらにdrainage法は,pancreaticoenterostomyと,transenteric antegrade stentingに分けられる.EUS‒PDは有用な方法であるが,専用の処置具は存在せず,手技の難易度も高く,また重篤な偶発症も存在するため,十分な技量を有する術者が慎重に適応を決定し施行すべきである.

[ Summary ] Pancreatic ductal hypertension associated with several pancreatic conditions, including chronic pancreatitis, pancreatic duct stones, and stenosis of the anastomotic site after pancreaticoenterostomy, cause epigastric and back pain. Endoscopic drainage of the main pancreatic duct, using a duodenoscope or enteroscope, is an effective treatment to relieve these symptoms. However, sometimes difficult cases were encountered using conventional endoscopic procedures because of tight stricture, stones, or anatomical reasons after operation.
Recently, endoscopic ultrasound (EUS)‒guided interventions have become more common and EUS‒guided pancreatic duct access is reported as an alternative approach method after conventional endoscopic procedures have failed. Drainage of an obstructed pancreatic duct under EUS guidance has evolved into viable techniques suitable for patients with failed ERCP and/or altered surgical anatomy. EUS‒guided pancreatic duct intervention is divided into two types, antegrade stent placement and retrograde stent placement using rendezvous techniques, following EUS‒guided pancreatography. Although EUS‒guided pancreatic duct drainage (EUS‒PD) is an effective salvage method, the technique is not always successful and often fails, even were performed by skilled endosonographers. Therefore, we should consider the indications and contraindications of EUS‒PD.
