| Abstract: | Background: Although many reports have documented pain relief achieved by pancreatic stenting, the effect of stenting on pancreatic function is less clear. In addition, the effects of stent caliber and patency have not been considered in most previous studies. Pain and pancreatic function after stenting of the main pancreatic duct (MPD) were examined. Methods: Records of 24 patients with chronic pancreatitis who had an MPD stricture treated with a 10‐Fr stent from June 1996 to June 2002 were reviewed. The average age was 57.0 ± 1 years, and the male : female ratio was 7 : 1. Eleven patients had diabetes mellitus. Stent patency, pancreatic pain and pancreatic endocrine and exocrine function were examined before stenting and 6 months after stenting. Stenting was continued for 1 year or more, with repeated stent exchange every 3 months. Results: The stent became occluded in 29% of cases, migration occurred in 15% of cases, and the 50% patency time was 125 days. Pancreatic pain was relieved by stenting in all cases. The diameter of the MPD, the Bentiromide test value, weight and body mass index were improved. Conclusion: Stenting relieves blockage of the main pancreatic duct and provides both pain relief and preservation of residual pancreatic function. |
