Chronic pancreatic pain successfully treated by endoscopic ultrasound-guided pancreaticogastrostomy using fully covered self-expandable metallic stent

摘要

One of the most common symptoms presenting in patients with chronic pancreatitis is pancreatic-type pain.Obstruction of the main pancreatic duct in chronic pancreatitis can be treated by a multitude of therapeutic approaches,ranging from pharmacologic,endoscopic and radiologic treatments to surgical interventions.When the conservative treatment approaches fail to resolve symptomatic cases,however,endoscopic retrograde pancreatography with pancreatic duct drainage is the preferred second approach,despite its well-recognized drawbacks.When the conventional transpapillary approach fails to achieve the necessary drainage,the patients may benefit from application of the less invasive endoscopic ultrasound(EUS)-guided pancreatic duct interventions.Here,we describe the case of a 42-year-old man who presented with severe abdominal pain that had lasted for 3 mo.Computed tomography scanning showed evidence of chronic obstructive pancreatitis with pancreatic duct stricture at genu.After conventional endoscopic retrograde pancreaticography failed to eliminate the symptoms,EUS-guided pancreaticogastrostomy(PGS)was applied using a fully covered,self-expandable,10-mm diameter metallic stent.The treatment resolved the case and the patient experienced no adverse events.EUS-guided PGS with a regular biliary fully covered,self-expandable metallic stent effectively and safely treated pancreatictype pain in chronic pancreatitis.
