摘要
目的评价经直肠腔内超声（ERUS）实时组织弹性成像在老年人进展期直肠癌分期诊断中的应用价值。方法对2014年6月至2015年10月我院收治的50例进展期直肠癌患者行经ERUS及实时组织弹性成像检查，其分期结果与术后病理进行对照。结果经ERUS对进展期直肠癌（T3）分期准确率为90．0％（45／50）、敏感度93．5％（43／46）、特异度50．0％（2／4）；实时组织弹性成像在进展期直肠癌（T3）分期准确率为84．0％（42／50）、敏感度89．1％（41／46）、特异度25．0％（1／4），两者联合应用对进展期直肠癌（T3）分期准确率为96．0％（48／50）、敏感度97．8％（45／46）、特异度75．0％（3／4），ERUS、实时组织弹性成像、两者联合应用准确率、敏感度差异无统计学意义（Х^2=4．000、3．100，P=0．373、0．542），与病理结果一致性检验Kappa值分别为0．S31、0．252、0．728。结论经ERUS实时组织弹性成像与常规ERUS结果比较虽未能提高诊断准确率，但在诊断进展期直肠癌分期时的准确率也较高，与常规ERUS联合应用可进一步提高进展期直肠癌的分期准确率。
Objective To evaluate the value of endorectal ultrasound （ERUS）combined with real-time elastography in the staging of advanced rectal cancer in elderly patients. Methods A total of 50 patients with advanced rectal cancer underwent endorectal ultrasound and real-time tissue elastography imaging at our hospital from Jun. 2014 to Oct. 2015. Their staging results were compared with postoperative pathology. Results The accuracy, sensitivity and specificity of ERUS in the staging of advanced rectal caneer（T3）were 90% （45/50）, 93.5% （43/46） and 50% （2/4）, respectively. The accuracy, sensitivity and specificity of real-time elastography in the staging of advanced rectalcancer（T3）were 84%（42/50）, 89.1%（41/46）and 25%（1/4）, respectively. With the combination of the two techniques, the accuracy, sensitivity and specificity in the staging of advanced rectal caneer（T3） were 96% （48/50）, 97. 8% （45/46） and 75%（3/4）, respectively. There was no significant difference in accuracy and sensitivity（Х^2 = 4. 000 and 3. 100, P= 0. 373 and 0. 542）between the three approaches. Kappa values between each of the three approaches and surgical pathology were 0. 531, 0. 252 and 0. 728, respectively. Conclusions Real-time tissue elastograpby in the diagnosis and staging of advanced rectal cancer can be enhanced when used in combination with endorectal ultrasound.
