Electrocoagulation is an effective treatment modality for localized cancer of the distal rectum. Proper selection remains the key to successful treatment. Of potentially curable patients with cancer of the rectum followed up for a median of five years, 69 per cent had no evidence of cancer at the end of the study period. Gross tumor morphology defined two distinct groups with regard to outcome after electrocoagulation. Ninety-two per cent of patients with polypoid/exophytic tumors as compared to 33 per cent of patients with ulcerative lesions had successful treatment. Based on these results, the authors believe that lesions that are exophytic represent early cancers with a low incidence of nodal spread and, as such, can be treated by electrocoagulation with confidence. As a palliative measure, the the authors found electrocoagulation to yield equivocal results.
电凝术是治疗直肠远端局限性癌症的一种有效方法。正确选择是成功治疗的关键。对可能治愈的直肠癌患者进行了中位时间为五年的随访，在研究期末，69%的患者无癌症迹象。大体肿瘤形态在电凝术后的预后方面界定了两个不同的组。息肉样/外生性肿瘤患者中有92%治疗成功，而溃疡性病变患者中这一比例为33%。基于这些结果，作者认为外生性病变代表早期癌症，淋巴结转移发生率低，因此可放心用电凝术治疗。作为一种姑息性措施，作者发现电凝术的效果不明确。
