本文报告５９例消化道肿瘤经内镜用高频电切治疗的经验。其中息内摘除３１例，粘膜下肿物９例，早期胃癌４例，伴梗阻的食管、贲门、胃癌９例，胃粘膜大活检６例。术后仅２例有轻到中等量出血；形成溃疡经正规治疗约在２～４周痊愈。本文对良性肿瘤与恶性肿瘤的关系，早期胃癌局部切除的可行性，胃粘膜大活检的价值做了讨论。提出高频电切是最好的预防和早期诊治消化道癌肿的方法。
This article reports 59 cases of digestive tract tumors treated with endoscopic high-frequency electrosurgical treatment. Among them, 31 cases were enucleated, 9 cases were submucosal tumors, 4 cases were early gastric cancer, 9 cases were esophageal, cardiac, gastric cancer with obstruction, and 6 cases had large gastric biopsy. Only 2 cases had mild-to-moderate hemorrhage after the operation; ulcers were healed by regular treatment in about 2 to 4 weeks. This article discusses the relationship between benign and malignant tumors, the feasibility of local resection of early gastric cancer, and the value of large biopsy of gastric mucosa. Proposed that high-frequency cutting is the best way to prevent and early diagnosis and treatment of digestive tract cancer.
