该文报告了22例内痔出血患者采用肛门镜下硬化剂注射治疗前后肛管括约肌压力变化，探讨内痔硬化剂注射治疗后对肛管括约肌生理功能的影响。结果表明肛管压在注射硬化剂治疗后肛管括约肌的静息压和收缩压均明显下降，与治疗前相比距肛缘1cm、3cm处肛管静息压P值分别为＜0．007及＜0．001，肛管收缩压P＜0．05，近期止血率达100％。认为采用肛门境下硬化剂注射治疗具有方法简便，安全有效，可反复注射治疗，无并发症等优点，并可明显降低肛管内静息压和收缩压，减少内痔复发。
This article reports the changes of anal sphincter pressure in 22 patients with hemorrhoiosis hemorrhoids before and after the injection of sclerosing agent for treatment of internal hemorrhoid to investigate the effect of internal hemorrhoids sclerotherapy on the physiological function of anal sphincter. The results showed that the resting pressure and systolic pressure of the anal sphincter were significantly decreased after treatment with injection of sclerosant. The values of resting resting pressure of anal canal at 1cm and 3cm were <0.007 And <0.001, anal systolic pressure P <0.05, the recent hemostasis rate of 100%. That the use of anus Hypodermic injection therapy has the advantages of simple, safe and effective method, repeated injection therapy, no complications, and can significantly reduce the anal pressure and systolic blood pressure to reduce the recurrence of hemorrhoids.
