Abstract:
BACKGROUND:In recent years, the morbidity of chronic pancreatitis has been increasing dramaticaly with lifestyle changes. Fortunately, endoscopic pancreatic stenting for patients with chronic pancreatitis shows favorable clinical prospects.OBJECTIVE:To introduce the advantages and disadvantages of various stent materials and to review the development and clinical application of pancreatic stents.METHODS: With the key words of chronic pancreatitis, pancreatic stent in Chinese and English, respectively, a computer-based search was performed for articles published in CNKI and PubMed databases from January 2005 to November 2016. After the initial screening, articles related to endoscopic pancreatic stenting usedin vitro,in vivo or in clinic were included.RESULTS AND CONCLUSION: Endoscopic pancreatic stenting has become a recognized treatment for chronic pancreatitis in recent years. Therefore, the development and application of the materials of pancreatic duct stents appear to be particularly important. According to different materials, pancreatic duct stents can be classified into plastic stents, fully covered self-expandable metal stents, and biodegradable stents. The complications, including stent migration and secondary surgery, frequently appear in the clinical use of plastic pancreatic duct stents and self-expandable metal stents, although they have been widely used in clinical practice. Biodegradable pancreatic duct stents can be degraded completely in the pancreatic duct within the expected time, and thereby avoid several complications. Consequently, the exploitation and application of biodegradable pancreatic duct stents have become an issue of concern.
