早期直肠癌可经肛门局部切除术(TAE)治愈,它仅适用于PT_1或PT_2的病人。TAE的关键是明确癌的浸润深度。本文就经直肠内窥超声(TRUS)对肿瘤的浸润深度与病理分期进行了比较研究。 本文研究TRUS检查原发性直肠癌62例的分期(UT),UT_18例,UT_224例,UT_327例,UT_43例,;UT_1和UT_2共32例,其中15例(UT_17例,UT_28例)行TAE术,根治术(UT_1)12例,与术后标本进行病理对比研究,UT_1分期与术后病理分期完全符合,UT_2中11例与病理分期一致, 3例为PT_1 (15％),6例为PT_3(30％);6例PT_3中,3例仅局限在壁内受侵(一例为显微镜下浸润,2例原发壁
Early colorectal cancer can be cured by local anal resection (TAE), which is only applicable to patients with PT_1 or PT_2. The key to TAE is to determine the depth of invasion of cancer. In this paper, the depth of tumor invasion and pathological staging were compared by transrectal endoscopic ultrasonography (TRUS). This article studies TRUS examination of primary rectal cancer in 62 cases of the stage (UT), UT_18 cases, UT_224 cases, UT_327 cases, UT_43 cases,; UT_1 and UT_2 a total of 32 cases, including 15 cases (UT_17 cases, UT_28 cases) TAE surgery , 12 cases of radical mastectomy (UT_1) were compared with postoperative specimens. UT_1 staging and postoperative pathological stages were completely consistent. 11 cases were consistent with pathological stages in UT_2, 3 were PT_1 (15%), and 6 were PT_3. (30%); In 6 cases of PT_3, 3 cases were confined to intramural invasion (1 case was infiltrated by microscope and 2 cases were primary wall
