Event or Problem Description
Olympus reviewed the following literature "case report transjejunal endoscopic ultrasound-guided pancreatic drainage for pancreatic jejunostomy stricture using a forward-viewing echoendoscope in a patient with altered anatomy."     literature summary: pancreatic jejunostomy stricture (pjs) is one of the major late complications after pancreaticoduodenectomy.Endoscopic ultrasound-guided pancreatic drainage (eus-pd) is considered a salvage treatment for symptomatic pjs after endoscopic retrograde pancreatography failure; however, the technical success rate of the endoscopic treatment of pjs remains unsatisfactory, mainly due to surgically altered anatomy.Herein, we describe a case of pjs successfully treated with transjejunal eus-pd using a forward-viewing echoendoscope.A (b)(6) man who suffered from repetitive severe back pain due to pjs was referred to our hospital.Since transgastric eus-pd was difficult, we attempted transjejunal eus-pd using a forward-viewing echoendoscope.To facilitate scope insertion, we first straightened the afferent jejuna! loop and placed a stiff guidewire.With this scheme, we successfully performed transjejunal eus-pd and placed a 5-fr plastic stent.In conclusion, this technique is useful for treating patients with pjs when transgastric euspd is difficult.    type of adverse events/number of patients: acute pancreatitis n=1.  this article includes 3 reports: patient identifier (b)(6): na-u200h-8019.Patient identifier (b)(6): sif-h290s.Patient identifier (b)(6): tgf-uc260j.This report is 3 of 3 for patient identifier (b)(6): tgf-uc260j.
