1、一例直肠癌患者的循证治疗临床背景：病史：患者男性，45岁，因“反复便血2月”入院。近两月前，患者无 明显诱因下出现反复出现便血，呈暗红色，量不多,无发热、无恶心、呕吐，无腹 痛腹胀，无肛周疼痛，大便次数增多，一天2-3次，大便成形，无大便变细。体格检查：体温：37.2C；脉搏：85次/分；呼吸：20次/分；血压： 128/72mmHg。一般情况尚好，自动体位。皮肤巩膜无明显黄染，心肺(一)。 腹部平坦，腹无压痛、反跳痛(-)，肝脾肋下未触及，未及腹部肿块。双侧下 肢无水肿，神经系统体征(一)。肛门指检：未及直肠肿块，指套染血。入院后检查：B超：肝、胆、脾、胰、肾未见明显异常。电子肠镜提示： 距
2、肛约10厘米一直肠肿块，占肠腔1/3圈，取活检二处，余结肠未见明显异 常。活检病理：直肠中分化腺癌。诊断：直肠癌。收入我院进行手术治疗一. 提出临床问题患者直肠癌诊断明确，治疗方式传统术式为：直肠癌根治术(Dixon)。但随 着腹腔镜技术的发展，以及其给病人带来创伤少，恢复快的特点越来越引起重视。 病人家属提出：像患者的病情是否适合腹腔镜手术，与开腹手术相比其根治性如 何，是否安全？二. 证据检索1. 证据来源：PUBMED 和 Cochrane 图书馆2, 检索词和检索策略：(1) 检索词：直肠癌rectal cancer OR rectal carcinoma、开放手术open abdom
