【摘要】:目的: 超聲胃腸充盈造影檢查是通過口服超聲助顯劑將胃腸道充盈以排除氣體后直接經(jīng)腹對胃腸道進(jìn)行的超聲檢查項(xiàng)目。目前該檢查在全國范圍內(nèi)開展較少,本研究旨在評價(jià)超聲胃腸充盈造影檢查對胃癌TNM分期的診斷價(jià)值,,以促進(jìn)臨床對該檢查的認(rèn)知。 材料與方法: 選擇經(jīng)胃鏡活檢確診的胃癌患者50例,于術(shù)前一周內(nèi)行胃腸充盈造影超聲檢查,運(yùn)用二維超聲觀察腫瘤的大小、形態(tài)、浸潤程度以及淋巴結(jié)轉(zhuǎn)移情況和有無遠(yuǎn)處轉(zhuǎn)移,依據(jù)2010年國際抗癌聯(lián)盟/美國癌癥聯(lián)合委員會(UICC/AJCC)制定的TNM分期標(biāo)準(zhǔn)評估胃癌的分期。將評估結(jié)果與術(shù)后病理分期進(jìn)行比較,分別計(jì)算二者間T分期、N分期、M分期的Kappa值,Kappa≥0.75為一致性較好,0.75>Kappa≥0.04為一致性一般,Kappa<0.4為一致性較差。從而評價(jià)超聲胃腸充盈造影檢查對胃癌TNM分期的診斷價(jià)值。本論文中所有數(shù)據(jù)統(tǒng)計(jì)均采用統(tǒng)計(jì)學(xué)軟件SPSS19進(jìn)行分析。 結(jié)果: 超聲診斷結(jié)果與術(shù)后病理分期比較: T1為9例,超聲胃腸充盈造影檢查明確診斷5例、準(zhǔn)確率為55.6%(5/9),另外4例中2例過深診斷為T2、2例過深診斷為T3;T2為11例,超聲胃腸充盈造影檢查明確診斷6例、準(zhǔn)確率為54.5%(6/11),另外5例中4例過深診斷為T3、1例過深診斷為T4;T3為19例,超聲胃腸充盈造影檢查明確診斷15例、準(zhǔn)確率為78.9%(15/19),另外4例過深診斷為T4;T4為11例,超聲胃腸充盈造影檢查明確診斷10例、準(zhǔn)確率為90.9%(10/11),另外1例過淺診斷為T3。超聲胃腸充盈造影檢查對胃癌浸潤深度T分期的總準(zhǔn)確率為72%(36/50)。二者間Kappa值為0.608,一致性一般。 N0為13例,超聲胃腸充盈造影檢查明確診斷10例、準(zhǔn)確率為76.9%(10/13),另外3例中1例過深診斷為N1、2例過深診斷為N2;N1為15例,超聲胃腸充盈造影檢查明確診斷12例、準(zhǔn)確率為80%(12/15),另外3例中1例過深診斷為N2、1例過深診斷為N3,1例過淺診斷為N0; N2為16例,超聲胃腸充盈造影檢查明確診斷13例、準(zhǔn)確率為81.3%(13/16),另外3例中2例過深診斷為N3,1例過淺診斷為N1; N3為6例,超聲胃腸充盈造影檢查明確診斷6例、準(zhǔn)確率為100%(6/6)。超聲胃腸充盈造影檢查對淋巴結(jié)轉(zhuǎn)移程度N分期的總準(zhǔn)確率為82%(41/50)。二者間Kappa值為0.755,一致性較好。 超聲胃腸充盈造影檢查對M分期的診斷與病理分期結(jié)果完全一致。 結(jié)論: 1.超聲胃腸充盈造影檢查具有檢出率高、診斷準(zhǔn)確、無痛無創(chuàng)、可重復(fù)檢查性好的優(yōu)點(diǎn)。 2.超聲胃腸充盈造影檢查診斷胃癌T分期的準(zhǔn)確率一般。 3.超聲胃腸充盈造影檢查診斷胃癌N、M分期的準(zhǔn)確率較高。 4.超聲胃腸充盈造影檢查可作為胃癌篩查及術(shù)前評估TNM分期的常規(guī)檢查。
[Abstract]:Objective: ultrasound gastroenterography is a kind of ultrasound examination which fills the gastrointestinal tract with oral ultrasound aids to remove gas and directly through the abdomen. The purpose of this study was to evaluate the diagnostic value of ultrasonography in TNM staging of gastric cancer and to promote the clinical understanding of this examination. Materials and methods: fifty patients with gastric cancer diagnosed by gastroscopy biopsy were examined with Gastrointestinal filling ultrasonography within one week before operation. The size and shape of the tumor were observed by two-dimensional ultrasound. The degree of invasion, lymph node metastasis and distant metastasis were evaluated according to the TNM staging criteria established by the International Union against Cancer / American Cancer Joint Commission (UICC/AJCC) in 2010. The Kappa values of T stage, N stage and M stage were calculated respectively. Kappa 鈮
