title: Endoscopic therapy for chronic pancreatitis.
abstract: OBJECTIVE
  To summarize recent data on techniques, efficacy and complications of endoscopic management of chronic pancreatitis.
  
  
  RESULTS
  Extracorporeal shock wave lithotripsy with or without endoscopic retrograde cholangiopancreatography is the first-line treatment for large painful obstructive pancreatic duct calculi. Use of preextracorporeal shock wave lithotripsy secretin could result in better stone clearance. The first-line treatment for dominant pancreatic duct strictures is placement of a single 10-Fr polyethylene stent with planned exchanges every 3 months until 1 year. Other endoscopic approaches that have shown good efficacy include placement of simultaneous multiple plastic stents and fully covered self-expanding metallic stents. Endoscopic options to treat chronic pancreatitis-associated benign biliary strictures include single and simultaneous multiple plastic stenting and fully covered self-expanding metallic stents. The European Society of Gastrointestinal Endoscopy recommends multiple plastic stenting for such strictures, although fully covered self-expanding metallic stents should be currently used under research settings. Endoscopic ultrasonography-guided cholangiopancreatography and pancreatobiliary drainage is an evolving option for chronic pancreatitis-related ductal obstruction after failed endoscopic retrograde cholangiopancreatography. Recent data have supported the safety and efficacy of endotherapy for chronic pancreatitis in children.
  
  
  CONCLUSIONS
  Endotherapy is the first line of management in chronic pancreatitis with symptomatic pancreatobiliary ductal obstruction. Further studies are required in certain key areas such as use of fully covered self-expanding metallic stents for pancreatic ductal and biliary strictures and endoscopic ultrasonography-guided pancreatobiliary drainage after failed endoscopic retrograde cholangiopancreatography.
