Of 2625 consecutive colonoscopic examinations, 122 stenotic lesions interfered with endoscopy. The sigmoid was the most frequent site of stenosis (64%). Of the two types of endoscopic patterns, type A, in which there is an intraluminal protruding mass, is the most frequent, and type B, in which a segment of colon gradually narrows, has intact mucosa. Adenocarcinoma was the most frequent cause of type A (83%), and complications related to diverticular disease (32%) and adenocarcinoma (27%) were most often associated with type B. Colonoscopy, guided multiple biopsies, and brushing cytology gave high diagnostic accuracy for type A lesions. In type B cases, brushings were usually negative.
在连续进行的2625次结肠镜检查中，有122处狭窄性病变影响了内镜检查。乙状结肠是最常见的狭窄部位（64%）。在两种内镜类型中，A型（腔内有突出肿物）最为常见，B型（结肠某段逐渐变窄且黏膜完整）次之。腺癌是A型病变最常见的原因（83%），与憩室病相关的并发症（32%）和腺癌（27%）最常与B型病变相关。结肠镜检查、多次活检引导以及刷检细胞学检查对A型病变具有较高的诊断准确性。在B型病例中，刷检通常为阴性。
