From April 1985 to March 1995, colonoscopy was carried out at our institution in 24,059 patients, 31,800 times in symptomatic and/or asymptomatic average risk persons. 184 submucosal invasive carcinomas were detected. Unlike protruding-type lesion, the depressed-type invades the submucosal layer, even though the size is within 10 mm. The depressed type of invasive carcinoma accounted for 20 lesions, and represented 10.9% (20 of 184) of all the invasive carcinomas. The pit pattern of depressed-type lesions shows a small round pit (type IIIs pit pattern) and that of carcinoma lesions shows the irregular pit and non-structure (type V pit pattern).
1985年4月至1995年3月，我院对24059例患者进行了结肠镜检查，对有症状和/或无症状的平均风险人群共进行了31800次检查。检测到184例黏膜下浸润癌。与隆起型病变不同，凹陷型病变即使大小在10mm以内也会侵犯黏膜下层。凹陷型浸润癌有20例，占所有浸润癌的10.9%（184例中的20例）。凹陷型病变的凹坑形态表现为小圆坑（III s型凹坑形态），而癌性病变的凹坑形态表现为不规则凹坑和无结构（V型凹坑形态）。
