弥散型He-Ne激光治疗放射性直肠炎的临床研究

目的探讨弥散型He-Ne激光直肠内照射对放射性直肠炎的临床治疗作用。方法将功率为30 mW、能量密度为3.62 J/cm2弥散型He-Ne激光导入直肠,使He-Ne激光直接照射直肠病变黏膜,观察患者直肠出血、直肠疼痛、腹泻等,比较治疗前后患者直肠黏膜病理组织学的改变。结果 He-Ne激光可以显著减少放射性直肠炎患者的直肠出血,对直肠疼痛、腹泻等症状的影响不大,能明显减轻黏膜组织的炎症反应,并能促进黏膜的修复。结论弥散性He-Ne激光直肠腔内照射对放射性直肠炎所致的直肠出血有较好的治疗作用。

Study on the Therapeutic Effect of Dispersive He-Ne Laser on Radiation Proctitis

Objective To study the therapeutic effect of dispersive He-Ne laser on radiation proctitis. Methods Sent He-Ne laser to the rectum,irradiated the mucosa lesions of the rectum with He-Ne laser,observed the major therapeutic effects of He-Ne laser,including but not limited to rectal bleeding and pain,and diarrhea,and compared the histopathological changes of the rectum mucosa before and after the treatment. Results For radiation proctitis patients,He-Ne laser can significantly reduce significantly rectal bleeding,reduce the and inflammatory reaction of mucosal tissue inflammatory reaction,and as well as can facilitate mucosal tissue repair,but has little effect in relieving other symptoms,such as pain and diarrhea. Conclusions The laser irradiation in the rectal cavity with dispersive He-Ne is effective in treating the bleeding caused by radiation proctitis.
