6、摘要]目的探討應(yīng)用CEUS引導(dǎo)經(jīng)皮穿刺活檢對(duì)胰腺占位性病變的臨床應(yīng)用價(jià)值。方法對(duì)因胰腺占位性病變需行穿刺活檢、但常規(guī)超聲定位困難的49例患者行CEUS引導(dǎo)下經(jīng)皮穿刺活檢,以所取組織能夠作出明確病理診斷為取材滿意;隨訪至少6個(gè)月,以術(shù)后病理診斷或隨訪影像學(xué)檢查結(jié)果為最終臨床診斷。結(jié)果本組穿刺活檢滿意率為95.92%(47/49),取材滿意者穿刺活檢的診斷準(zhǔn)確率為97.87(46/47)。術(shù)后惡心嘔吐、發(fā)熱及膽汁性腹膜炎各1例(1/49,2.O4)。結(jié)論對(duì)于常規(guī)超聲不能準(zhǔn)確定位的胰腺占位性病變,以CEUS引導(dǎo)穿刺可以提高取材的準(zhǔn)確性,降低并發(fā)癥發(fā)生率。[關(guān)
