Abstract:
Objective To investigate the clinical characteristics of incarcerated stones at duodenal papilla and to evaluate the efficacy of endoscopic needle-knife sphincterotomy ( NKS ) . Methods Data of 316 patients who underwent endoscopic treatment for incarcerated stones at duodenal papilla between 2007 and 2016 were retrospectively studied. Endoscopic treatment outcomes, proportion changes of incarcerated stones in total number of choledocholithiasis, changes of diameter of common bile duct( CBD) and diameter of incarcerated stones were analyzed. Results Obstruction was relieved and endoscopic nasobiliary drainage was successfully performed in all 316 cases ( 100. 0％) , and NKS procedures were performed in 231 patients ( 73. 1％) . The incidence of incarcerated stone at duodenal papilla in choledocholithiasis showed a decreased trend ( P=0. 000) . Diameters of both CBD and incarcerated stones showed a decreased trend in hierarchical data by year ( P=0. 000, P=0. 000) . Conclusion The incidence of incarcerated stones at duodenal papilla in choledocholithiasis, the diameters of CBD and incarcerated stones are all on the decrease. NKS is the primary method for treatment of incarcerated stones at duodenal papilla.
