摘　　要：本文报道经病理或手术证实的大肠癌105例,术前作腔内 B 型超声检查67例,其中6例估计浸润层次过深,准确率91.0%,敏感性100%,CT 检查73例中3例估计浸润过浅,准确率95.9%,敏感性90.0%,CT 发现淋巴结的敏感性为68.9%。作者认为腔内 B 型超声可作为直肠癌术前常规检查,当 B 超显示癌肿穿透全层并浸润周围组织时可加做 CT.The infiltration depth of 89 rectal cancers proved by pathological or operativc findingswas evaluated preoperatively with intrarectal B ultrasound(BUS)(67 cases)and CT(73cases).Six of the 67 examined with BUS were overestimated for infiltration depth and 3of the 73 examined with CT were underestimated in infiltration.The sensitivity of CT toymphnode metastasis was 68.9%.In 15 patients,BUS revealed tumor limited in muscu(?)liaris so that sphincter saving operation was performed and the extent of tumor wasconfirmed by pathology.Thirty-five patients with a digital rectal examination diagnosis offixed tumor were evaluated with BUS.In 12 of the 35,BUS showed tumors were limitedin the rectal wall and the tumors were radically resected; 23 of the 35 had tumors spreading toperirectal tissues,9 were radically reseeted and 14 had colostomy.So intrarectal BUShelped to make a pre(?)peration plan.However,BUS can only demostrate the infiltrationdepth of tumor while CT can tell whether the tumors have spreaded to the perirectaltissues or lymphnodes are enlarged.
