摘要:
目的 探究老年晚期恶性梗阻性黄疸患者实时超声弹性成像定量分析与经皮经胆道穿刺引流术(PTCD)预后的关系。 方法 回顾性选取2017年5月至2021年5月间,昆明市第一人民医院112例行PTCD治疗的老年晚期恶性梗阻性黄疸患者,根据患者预后情况分为预后不良(n = 42)与预后良好组(n = 70)。比较2组临床资料、PTCD前后实时超声弹性成像定量指标,分析实时超声弹性成像定量指标与Child-Pugh评分的相关性、PTCD术后实时超声弹性成像定量指标与老年晚期恶性梗阻性黄疸患者PTCD预后的关系,绘制受试者工作特征(ROC)曲线,评价PTCD术后实时超声弹性成像定量指标对老年晚期恶性梗阻性黄疸患者PTCD预后的诊断价值。 结果 2组梗阻部位、总胆红素水平、Child-Pugh评分差异有统计学意义(P < 0.05);预后不良组PTCD术后实时超声弹性成像定量指标应变均值较预后良好组低,蓝色领域百分比较预后良好组高(P < 0.05);老年晚期恶性梗阻性黄疸患者应变均值、蓝色领域百分比与Child-Pugh评分有关(P < 0.05);应变均值、蓝色领域百分比均为老年晚期恶性梗阻性黄疸患者PTCD预后患者独立影响因素(P < 0.05);应变均值、蓝色领域百分比联合诊断老年晚期恶性梗阻性黄疸患者PTCD预后的AUC为0.862。 结论 老年晚期恶性梗阻性黄疸患者实时超声弹性成像定量测量应变均值、蓝色领域百分比与患者肝功能及预后有关,PTCD术后进行实时超声弹性成像定量,有助于疾病预后预测,在临床工作中具有重要意义。 Abstract:Objective To explore the relationship between quantitative analysis of real-time ultrasound elastography and the prognosis of percutaneous transbiliary drainage (PTCD) in elderly patients with advanced malignant obstructive jaundice. Methods Retrospectively selected 112 elderly patients with advanced malignant obstructive jaundice who underwent PTCD treatment in our hospital between May 2017 and May 2021 were divided into poor prognosis (n = 42) and good prognosis groups (n = 70) according to their prognosis. We compared the clinical data of the two groups, the quantitative indexes of real-time ultrasound elastography before and after PTCD, analyzed the correlation between the quantitative indexes of real-time ultrasound elastography and Child-Pugh score, the quantitative indexes of real-time ultrasound elastography after PTCD and the prognosis of PTCD in elderly patients with advanced malignant obstructive jaundice, and drew the receiver operating characteristic (ROC) curve, and evaluated the value of real-time ultrasound elastography quantitative indicators for the prognosis of elderly patients with advanced malignant obstructive jaundice after PTCD. Results There were statistically significant differences in the site of obstruction, Child-Pugh score, and total bilirubin level between the two groups (P < 0.05). The mean value of strain of real-time postoperative ultrasound elastography quantitative index of PTCD in the poor prognosis group was lower than that in the good prognosis group, and the percentage of blue field was higher than that in the good prognosis group (P < 0.05). The mean value of strain and blue field percentage were associated with Child-Pugh score (P < 0.05). Strain mean value and blue field percentage were independent factors influencing PTCD prognosis in elderly patients with advanced malignant obstructive jaundice (P < 0.05).The AUC for the combined diagnosis of strain mean value and blue field percentage in elderly patients with advanced malignant obstructive jaundice for PTCD prognosis was 0.862. Conclusions Real-time ultrasound elastography quantitative measurement of mean strain and percentage of blue area in elderly patients with advanced malignant obstructive jaundice are related to the liver function and prognosis. Real-time ultrasound elastography quantification after PTCD can help predict the prognosis of the disease. It is of great significance in clinical work. -
