Abstract:
Objective To evaluate modified shortened scope for ERCP procedure in swine animal model.Methods A total of 17 male pigs were divided into the conventional endoscope group (shortened scope used on human,n =8) and the modified endoscope group (modified shortened scope,n =9).The success rates,time of access to the pylorus,biliary or pancreatic orifice,the cannulation time of biliary or pancreatic duct,the stenting time of biliary or pancreatic duct,the total time of procedure and the X-ray exposure time were compared between the two groups.Results The success rates were 2/8 and 9/9 in the conventional endoscope group and the modified endoscope group,respectively(P =0.002).There were significantly differences of the cannulation time of biliary duct(180.00 ± 37.89 s VS 55.22 ± 11.56 s,P =0.000),cannulation time of pancreatic duct(55.22 ± 11.56 s VS 56.56 ±29.19 s,P =0.015),the time of access to pancreatic orifice(21.50 ±7.33 min VS4.67 ±2.63 min,P =0.000) and the total time of procedure(55.13 ±5.64 min VS 31.67 ±8.25 min,P =0.000) between the two groups.There were no significant differences in the time of passing through the pylorus,the time of finding biliary orifice,the stenting time of biliary or pancreatic duct or the X-ray exposure time between the two groups.Conclusion The modified shortened scope can improve the success rate of short scope position,facilitate locating biliary or pancreatic orifice,improve the success rate of pancreatic duct cannulation and shorten the cannulation time of biliary or pancreatic duct and the total operation time.
