目的探讨扬州地区大肠息肉状病变患者的临床及病理学特点。方法对大肠息肉状病变患者的临床表现、内镜特点及病理资料进行总结和分析。结果 4500例肠镜检查者中,检出大肠息肉状病变539例,检出率11.98%。男346例,女193例。好发年龄以50～69岁为主,占46.38%。病理类型以腺瘤性息肉、炎性息肉为主,分别占53.06%、29.50%。息肉部位分别为盲肠9.70%、升结肠11.64%、横结肠9.58%、降结肠13.82%、乙状结肠24.36%、直肠30.91%。539例中有19例发生癌变,癌变率3.53%。管状腺瘤、混合性腺瘤、绒毛状腺瘤癌变率为2.82%、2.99%、9.68%;息肉直径0.6～1.0cm者癌变率0.44%,1.1～1.9cm者癌变率3.33%,≥2.0cm者癌变率11.48%。结论 50～69岁者大肠息肉状病变发病率较高;男性较女性易患大肠息肉;息肉好发部位为左半结肠;腺瘤性息肉常见,直径≥2.0cm及绒毛状腺瘤容易癌变。
Objective To investigate the clinical and pathological features of colorectal polyps in Yangzhou area. Methods The clinical manifestations, endoscopic features and pathological data of patients with polyposis colonic lesions were summarized and analyzed. Results Among 4500 cases of colonoscopy, 539 cases of colonic polyp lesions were detected, the detection rate was 11.98%. 346 males and 193 females. Good hair age to 50 to 69-year-old, accounting for 46.38%. Pathological types of adenomatous polyps, inflammatory polyps, accounting for 53.06%, 29.50%. Polyps were 9.70% cecum, ascending colon 11.64%, transverse colon 9.58%, descending colon 13.82%, sigmoid colon 24.36%, rectum 30.91%. Of the 539 cases, 19 had canceration, with a canceration rate of 3.53%. Tubular adenoma, mixed adenoma, villous adenoma canceration rate was 2.82%, 2.99%, 9.68%; polyp diameter 0.6 ~ 1.0cm cancer rate 0.44%, 1.1 ~ 1.9cm cancer rate 3.33%, ≥ 2.0cm The rate of canceration was 11.48%. Conclusions The incidence of colorectal polyps is higher in patients aged 50-69 years. Men are predisposed to colorectal polyps than women. Polyps are predominant in the left colon. Adenomatous polyps are common and diameter ≥ 2.0 cm and villous adenoma are easily cancerous.
