Two-hundred-forty patients with previously resected colorectal carcinoma were investigated for neoplasia of six months, 12 months and then at yearly intervals during a four-year period. Physical examination, occult blood, rigid sigmoidoscopy, barium enema and colonoscopy were used during the surveillance. Out of 304 colonoscopies, 68 were positive for neoplasia, 11 metachronous, and 17 recurrent cancers with 66 tubular adenomas and nine villous adenomas were found. Barium enema detected 38% of the lesions. Occult blood in stood was positive in 18.5%. The results of the methods of surveillance are analyzed and the relative value of each method is discussed.
对240例先前已切除结直肠癌的患者进行了为期四年的研究，在术后6个月、12个月时进行肿瘤检查，之后每年检查一次。监测期间采用了体格检查、潜血检查、硬式乙状结肠镜检查、钡灌肠和结肠镜检查。在304次结肠镜检查中，68次肿瘤检查呈阳性，发现11例异时性癌、17例复发性癌，还有66例管状腺瘤和9例绒毛状腺瘤。钡灌肠检测出38%的病变。潜血检查阳性率为18.5%。分析了监测方法的结果，并讨论了每种方法的相对价值。
