CT、B超在鑒別診斷急性闌尾炎患者中的應(yīng)用價(jià)值(1)
[摘要]目的 探討CT、B超在鑒別診斷急性闌尾炎中的應(yīng)用價(jià)值。方法 選取2017年4月~2018年4月在我科接受診斷的116例疑似急性闌尾炎患者為研究對(duì)象,所有患者均進(jìn)行CT、B超檢查,以實(shí)驗(yàn)室檢查結(jié)果為標(biāo)準(zhǔn),將CT、B超診斷結(jié)果進(jìn)行比較。結(jié)果 CT檢查的靈敏度為98.13%,高于B超檢查的87.85%,差異有統(tǒng)計(jì)學(xué)意義(P<0.05);CT檢查的特異度為77.78%,與B超檢查的33.33%比較,差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05);CT檢查的準(zhǔn)確率為96.55%,高于B超檢查的83.62%,差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。結(jié)論 CT檢查用于鑒別診斷急性闌尾炎,效果明顯優(yōu)于B超檢查。

[Abstract] Objective To explore the application value of CT and B-ultrasound examination in differential diagnosis of acute appendicitis. Methods Altogether 116 patients with suspected acute appendicitis who were diagnosed in our department from April 2017 to April 2018 were selected as the subjects of observation. All patients were examined by CT scan and B-ultrasonography. The diagnostic results of CT scan and B-ultrasonography were compared according to the results of laboratory examination. Results The sensitivity of CT examination was 98.13%, which was higher than that of B-ultrasound examination (87.85%), with statistically significant difference (P<0.05). The specificity of CT examination was 77.78%, compared with 33.33% of B-ultrasound examination, and the difference was not statistically significant (P>0.05). The accuracy of CT examination was 96.55%, which was higher than that of B-ultrasound examination (83.62%), with statistically significant difference (P<0.05). Conclusion CT examination is superior to B-ultrasonic examination in the differential diagnosis of acute appendicitis.

急性闌尾炎是臨床上一種常見(jiàn)的急腹癥,其發(fā)病急、病情變化快。對(duì)于急性闌尾炎的早期診斷與治療,可以有效降低并發(fā)癥的發(fā)生率[1]。部分急性闌尾炎患者癥狀不明顯,有多種疾病早期癥狀與之相似,臨床難以辨別,常出現(xiàn)誤診或漏診的狀況[2]。目前臨床診斷急性闌尾炎一般采取CT或B超影像學(xué)檢查以減少誤診或漏診。本研究探討了CT、B超鑒別診斷急性闌尾炎的應(yīng)用效果,現(xiàn)報(bào)道如下。
1資料與方法
1.1一般資料
選取2017年4月~2018年4月在我科接受診斷的116例疑似急性闌尾炎患者作為研究對(duì)象。納入標(biāo)準(zhǔn):兩組患者均知曉且自愿加入本次試驗(yàn);有發(fā)熱、嘔吐、惡心、右下腹劇痛等相關(guān)癥狀,均有麥?zhǔn)宵c(diǎn)壓痛等;血常規(guī)檢查顯示白細(xì)胞計(jì)數(shù)升高;均有手術(shù)指征[3]。排除標(biāo)準(zhǔn):有腹部手術(shù)史;有重要臟器疾;存在嚴(yán)重精神性疾病;出現(xiàn)手術(shù)禁忌癥狀;孕產(chǎn)期及哺乳期患者。研究對(duì)象中,男68例,女48例,年齡23~73歲,平均(46.22±3.54)歲,病程2~65 h,平均(11.32±3.90) h。本研究獲得醫(yī)院醫(yī)學(xué)倫理委員會(huì)審查批準(zhǔn)。
1.2方法
所有研究對(duì)象均給予術(shù)前CT、B超檢查。CT檢查:采用OPTIMA520/16排螺旋CT機(jī),囑患者仰臥位,檢查平掃范圍由膈頂至恥骨聯(lián)合下緣,設(shè)置參數(shù)為150~240 mAa、5 mm層厚、120 kV、5 mm間距、重建層為0.625 mm厚。根據(jù)患者病情嚴(yán)重程度、身體素質(zhì)情況評(píng)估是否需要增強(qiáng)掃描。在進(jìn)行增強(qiáng)掃描時(shí),需給予患者造影(高壓注射器靜脈注射碘海醇注射液90 ml,3 m/s注射速度,注射后延遲20 s再行掃描),并根據(jù)檢查患者實(shí)際的病變情況,重建原始圖像。B超檢查:采用超聲顯像儀,囑患者排空膀胱,檢測(cè)時(shí)取仰臥位,在患者麥?zhǔn)宵c(diǎn)使用高頻探頭加壓檢查,若未發(fā)現(xiàn)闌尾,即探查盲腸下段、盲腸外側(cè)、或后位闌尾的情況,如由于患者自身原因?qū)е嘛@示不清楚時(shí),可以取低頻探頭掃描。
1.3觀察指標(biāo)
記錄患者的CT、B超檢查結(jié)果,以實(shí)驗(yàn)室檢查結(jié)果為標(biāo)準(zhǔn),分別比較CT、B超的診斷結(jié)果[4]。, 百拇醫(yī)藥(夏亦祥 劉秀英)
