Abstract
The occurrence of papillary restenosis following endoscopic sphincterotomy is uncommon and usually reported as a late complication. Its frequency varies from 0.8% to 3% and at present, only a few reports describe the late complication rate for a mean follow-up exceeding 10 years. The diameter of the sphincterotomy opening diminishes by about 30% in the first year without further narrowing, suggesting that restenosis occurs mainly during the first post-sphincterotomy year. Papillary restenosis may be promoted by insufficient cutting and may depend on the indication for EST such as common bile duct stones, papillary stenosis, duodenal diverticular, sphincter of Oddi dysfunction. A bleeding sphincterotomy requiring a sclerosing injection is considered a potential risk factor for papillary stenosis. However, stenosis may develop in the absence of specific predisposing factors. A case of papillary restenosis following endoscopic sphincterotomy for gollstone pancreatitis in a 33-year-old female patient is herein reported.
