Effect of T-tube Sinus Choledochoscopy Combined with Electro-hydraulic Lithotripsy in the Treatment of Residual Stones after Biliary Calculi Op-eration
Objective To analyze the effect of T-tube sinus choledochoscopy combined with electro-hydraulic litho-tripsy in the treatment of residual stones.Methods A total of 50 patients with residual biliary stones after operation treated by Xuzhou Mining Hospital from July 2019 to July 2023 were selected for study,and were divided into control group(n=25)and study group(n=25)by random number table method.The control group underwent laparotomy,and the study group underwent T-tube sinus choledochoscopy combined with electro-hydraulic lithotripsy.The surgical in-dexes(operation time,blood loss,hospital stay),stone removal rate and complications were compared between the two groups.Results The operation time of the study group(182.57±19.38)min was longer than that of the control group,and the difference was not statistically significant(P>0.05).The amount of blood loss(15.37±4.35)mL and the length of hospitalization(6.12±2.21)d were shorter than those in the control group,and the differences were statistically sig-nificant(both P<0.05).The stone removal rate was 92.00%of the study group,higher than that of control group,and the difference was statistically significant(χ2=4.500,P<0.05).In the study group,postoperative fever occurred in 1 case,while in the control group,biliary tract hemorrhage occurred in 2 cases,pancreatitis occurred in 1 case and post-operative fever occurred in 4 cases,the total complication rate was higher than that in the study group,and the differ-ence was statistically significant(P<0.05).Conclusion Although it takes a long time to treat residual stones after bili-ary calculus,the combined treatment of T-tube sinus choledochoscopy and electro-hydraulic lithotripsy is a safe and effective treatment method with less trauma,high stone removal rate,low complication rate and clear curative effect.
