摘要
本动物实验提示65W功率的激光照射所致的肛管粘膜溃疡表浅,且很快愈合。照射时间缩短,照射分散多点,则照射区形成的疤痕范围大,这有利于内痔的萎缩。应用此原理,我们已用Nd-YAG激光治疗内痔和混合痔248例,即期疗效好。152例经随访一年以上,其便血、痔脱垂和排便不通畅现象有显著改善,其发生率分别由96.4％、76.6％和46.8％下降至2.8％、22.9％和6.9％。我们推荐65W功率的激光多点照射法。Ⅲ°环状痔的效果尚有待进一步提高。
Animal experiments demonstrated that ulcers in the anal mucosa caused by 65 W Nd-YAG laser were shallow and healed quickly. Application of the laser for a shorter time over multiple points resulted in much wider areas of fibrosis in the anal mucosa, submueosa and superficial muscular layer of the irradiated areas, and promoted shrinkage of the hemorrhoids. This information was utilized in clinical practice. 245 cases of internal and mixed piles were treated by applying Nd-YAG laser to the rectal and/or anal muoosa with good immediate results. Of them, 152 oases were followed-up for more than one year. The incidence of bleeding, prolapse of rectal mucosa and dygohasia were reduced from 96.4%, 76.6% and 46.8% to 2.8 %, 27.9% and 6.9%, respectively. We recommend treatment of internal or mixed hemorrhoids by 65W Nd-YAG laser applied for a short time and to multiple points. Results in annular third degree hemorrhoids are still disappointing and requires further investigation.
