A prospective study of the role of preoperative and routine follow-up colonoscopy in 75 patients with colon and rectal carcinoma disclosed that additional premalignant or malignant lesions were detected and successfully treated in 44 percent of patients. These included four synchronous and three metachronous carcinomas. Timely diagnosis and treatment of such tumors and secondary prevention of metachronous carcinomas by polypectomy is a major identifiable benefit of close follow-up examinations of these patients. No other test compares favorably with colonoscopy in this regard. These data support the conclusion that colonoscopy should be performed routinely preoperatively and every 6 to 12 months after colectomy for carcinoma.
一项针对75例结肠癌和直肠癌患者的前瞻性研究表明，术前和常规随访结肠镜检查发现，44%的患者检测到额外的癌前或恶性病变并得到成功治疗。其中包括4例同时性癌和3例异时性癌。及时诊断和治疗此类肿瘤以及通过息肉切除术对异时性癌进行二级预防是对这些患者进行密切随访检查的一个主要可识别益处。在这方面，没有其他检查能与结肠镜检查相媲美。这些数据支持这样的结论，即对于癌症患者，应在术前常规进行结肠镜检查，并在结肠切除术后每6至12个月进行一次。
