目的探討繼發(fā)性化膿性腹膜炎（secondary pyogenic peritonitis, SPP）的CT表現(xiàn)、顯示率及其解剖、病理基礎(chǔ)。
方法回顧性分析24例SPP的CT表現(xiàn)特征,著重觀察SPP在螺旋CT掃描中的基本CT表現(xiàn)和導(dǎo)致SPP的原發(fā)病灶及并發(fā)癥的CT表現(xiàn)以及它們的顯示率，并探討其解剖、病理基礎(chǔ)。
結(jié)果24例SPP的主要CT表現(xiàn)如下： 腹膜增厚16例(66.7%)，其中光滑規(guī)則增厚14例，不規(guī)則增厚2例； 腹腔積液15例(62.5%)； 腹腔游離氣體9例(37.5%)； 大網(wǎng)膜和小腸系膜水腫、增厚分別為8例(33.3%)、5例(20.8%)； 腸壁水腫、增厚5例(20.8%)； 腸曲間相互粘連6例(25.0%)。導(dǎo)致SPP的原發(fā)病灶及并發(fā)癥的CT表現(xiàn)： 不同程度地顯示出導(dǎo)致SPP原發(fā)病灶征象13例(54.2%)，合并腹膜后間隙炎癥13例(54.2%)，胸部改變13例(54.2%)，以及腹、盆腔膿腫6例(25.0%)。
結(jié)論SPP的CT主要表現(xiàn)包括壁腹膜增厚，腹腔積液、積氣，大網(wǎng)膜和小腸系膜水腫、增厚等； 次要表現(xiàn)包括腸壁水腫、增厚，腸曲間相互粘連等。應(yīng)用CT掃描診斷SPP，可顯示較豐富的CT征象以協(xié)助診斷。
