胃及结肠息肉,过去均需剖腹手术予以切除。自从纤维内窥镜应用于临床以来,经内窥镜活检通道插入电烙圈套,进行电烙息肉切除术,获得成功。这种方法对有蒂的息肉效果良好,但对广基或无蒂息肉的切除,有一定困难,效果不满意。已经有报导,局部注射抗肿瘤药物或其他药物,以形成溃疡,得以切除胃息肉样病变,但此法不能对所切除的病变作组织学检查。本文报导经过纤维胃镜,插入特制的注射针,注射95％酒精于胃息肉病变八例。 Stomach and colon polyps had to be removed by laparotomy in the past. Since the application of the fiberscope in clinic, the endoscopic biopsy channel has been inserted into the electrocoagulation snare to perform electrocautery polypectomy. This method works well for pedunculated polyps, but it has certain difficulties in the removal of broad-based or sessile polyps, and the effect is not satisfactory. It has been reported that local injection of anti-tumor drugs or other drugs to form ulcers can remove gastric polypoid lesions, but this method can not be used for histological examination of the resected lesions. This article reported that after fiberoptic gastroscopy, insert a special injection needle, injection of 95% alcohol in gastric polyps lesions in 8 cases.
