大肠早期癌变息肉的内镜诊治及随访

通过详细的病理学检查，从4000例内镜切除的息肉病人中发现121例病人为早期癌变息肉，根据癌组织侵润的深度和切缘是否有癌细胞残留决定行内科保守治疗或补做外科根治术，所有病人每年一次内镜检查，结果显示：33例m癌病人，27例切缘无癌细胞残留而且未做手术的sm1癌病人和38例补做根治术的sm2癌病人均未出现复发，1例切缘有癌细胞残留的sm1癌和3例sm2癌因未做根治术出现复发。

Endoscopic diagnosis and treatment of the early-stage malignant colorectal polyp and follow-up study]

In the past 20 years we have performed endoscopic removal of colorectal polyps in 4 000 cases, and thorough histological examination of the removed polyps identified 121 cases of early-stage malignant polyp. According to the depth of malignant invasion and whether malignant remnants were present after the initial surgical removal, conservative treatment or radical operation was implemented. During the follow-up study, endoscopy was performed once each year in all the patients with malignancies. No recurrence was found in the 33 patients with mucosa cancer or in the 27 patients with type I submucosa cancer who did not receive radical operation due to absence of malignant remnants or in the 38 patients with type II submucosa cancer who had the radical operation. Relapse occurred in 1 patient with malignant remnant and in another 3 cases of type II submucasa cancer without radical operation.
