[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.
