Abstract

目的 探讨直肠类癌在电子结肠镜及内窥镜超声小探头扫描下的特征,以指导直肠类癌诊治方案的选择。 方法 对34例电子结肠镜下怀疑直肠类癌的患者进行内窥镜超声小探头检查,了解肿物的来源、层次、大小、密度、边界、浸润深度及黏膜下层完整性,结合经肛门彩色超声及CT或磁共振成像结果进行综合分析,进一步指导直肠类癌的治疗(内窥镜下黏膜剥离术或外科切除)。 结果 本组34例直肠类癌的患者超声小探头示,肿物直径小于0.5 cm者6例,0.5~1.0 cm者21例,1.1~1.5 cm者4例,1.6~2.0 cm者2例,2.0 cm以上者1例;来源于黏膜肌层但黏膜下层完整连续者31例,黏膜下层受侵粘连者3例。适合内窥镜下切除者31例,适合外科经肛门局部切除者3例,其中大于2 cm者1例。本组34例术后大体标本病理及免疫组织化学结果均证实为直肠类癌,未发现远处转移的患者,随访1~3年未见局部复发及远处转移。 结论 肛门指诊、电子结肠镜结合超声小探头对直肠类癌的诊断有重要价值。内窥镜超声小探头可指导直肠类癌术式选择,也对术后疗效评价有着重要的参考价值。
