Technique of endoscopic ultrasonography-guided pancreatic duct intervention (with videos)

Abstract

To date, several endoscopic ultrasonography (EUS)-guided interventions have been reported. Of these interventions, EUS-guided pancreatic duct (PD) intervention seems to be the most difficult and challenging procedure to accomplish. We provide suggestions for EUS-guided PD intervention, which includes PD stenting and the rendezvous technique following EUS-guided pancreatography. PD stenting is performed between the PD and the gastrointestinal tract (stomach, duodenum, or jejunum). The rendezvous technique is performed using a guidewire across the papilla or anastomotic site for retrograde stent insertion. EUS-guided PD intervention is still challenging because it is not established yet. Thus, although EUS-guided PD intervention seems to be promising, it should be performed in selected patients such as those of failed standard endoscopic retrograde cholangiopancreatography.
