CT定量分析胰管结石体外冲击波碎石治疗效果

目的利用CT定量分析胰管结石体外冲击波碎石术(ESWL)治疗效果。方法回顾性分析接受胰管结石体外冲击波碎石术治疗的149例患者资料,所有患者均行螺旋CT腹部平扫,测量结石的CT平均值及最大横截面的面积,依据碎石后结石残留的大小分为完全碎石组与不完全碎石组,采用SPSS26.0软件进行处理分析,P<0.05为具有统计学差异。结果两组性别、结石CT平均值及面积差异具有统计学意义(P<0.05),进一步采用二元Logistic回归进行多因素分析胰管结石ESWL的独立危险因素,发现女性、结石CT平均值高及面积大是影响胰管结石ESWL疗效的独立危险因素。结论性别、结石CT平均值、面积与ESWL治疗效果有关,且女性、结石CT平均值高、面积大是导致结石破碎不完全的独立危险因素。

Objective To quantitatively analyze the therapeutic effect of extracorporeal shock wave lithotripsy(ESWL)for pancreatic duct stones by CT images.Methods The clinical data of 149 patients with pancreatic duct stones treated with extracorporeal shock wave lithotripsy were analyzed retrospectively.All patients underwent spiral CT abdominal plain scan.The mean CT value and maximum cross-sectional area of the stones were measured.The patients were divided into the complete lithotripsy group and the incomplete lithotripsy group according to the size of residual stones after lithotripsy.SPSS 26.0 software was used for processing and analysis.P<0.05 was considered statistically significant.Results There were significant differences in sex,mean CT value and area of stones between the two groups.Binary logistic regression was used to analyze the independent risk factors of ESWL in pancreatic duct stones.It was found that female,high mean CT value and large area of pancreatic duct stones were independent risk factors affecting the efficacy of ESWL in pancreatic duct stones.Conclusion Sex,mean CT value and area of stones are related to the therapeutic effect of ESWL,and female,high mean CT value and large area of stones are independent risk factors of incomplete stone fragmentation.
