目的:探讨胃肠镜下高频电凝电切息肉的临床应用价值。方法:336例胃肠息肉,息肉直径在0.5cm～2.0cm,采取内镜下1次切除,息肉直径2cm以上采取多步切除法。结果:术后黏膜表面光滑,无残留。少数病例术后出现渗血。对症处理后停止。结论:胃肠息肉未发生癌变前均可以采取胃肠镜下高频电凝电切术进行治疗。
Objective: To investigate the clinical value of gastrointestinal endoscopic polypectomy. Methods: A total of 336 cases of gastrointestinal polyps were examined. The diameter of the polyp was 0.5cm ~ 2.0cm. One endoscopic resection was performed. The multi-step excision was performed on the polyps more than 2cm in diameter. Results: The postoperative mucosal surface was smooth and without residue. A small number of cases of bleeding after surgery. Symptomatic treatment stopped. Conclusion: Gastrointestinal polyps can be treated with high-frequency electrosurgical excision of gastrointestinal endoscopy before carcinogenesis.
