结直肠绒毛腺瘤应在其恶变前予以手术切除。当不能手术时,采用内镜下激光治疗有一定的成功率,尽管有些报告提示这种疗法有相当高的复发率,但其很可能是由于过于考虑穿孔的危险性而未将肿瘤全部剔除所造成。光动力疗法(PDT)包括患者摄入一种光敏感但无毒性的药物(光致敏剂),在肿瘤组织中积聚,然后由低功率的光所激活。这种光药物相互反应产生细胞毒化学
Colorectal villous adenoma should be surgically removed before its malignant transformation. When surgery is not available, endoscopic laser treatment has a certain success rate. Although some reports suggest that this treatment has a relatively high recurrence rate, it is probably due to over-consideration of the risk of perforation without completely removing the tumor. Caused. Photodynamic therapy (PDT) involves the patient’s ingestion of a photo-sensitive but non-toxic drug (photosensitizer) that accumulates in the tumor tissue and is then activated by low-power light. This photo drug reacts with each other to produce cytotoxic chemistry
