本文研究肛管压力与极慢波(USW′s)的关系,以及内括约肌侧切除术(LIS)对压力波动的影响。肛管内压力波动十分明显,如不考虑波动的幅度和频率,波动可分为慢波,极慢波和自发性内括约肌松驰。方法:既往未行肛门直肠手术的30例肛裂患者和20例Ⅰ、Ⅱ度症状性痔患者,经LIS术治疗。术前,将带有换能器的导管插入直肠测肛管直肠压力,以2.5mm/s恒速退出导管,同时描记压力曲线。重复测3次后,再插入导管寻找直肠压力最高处,并在此位置持续记录30分钟,观察压力变化。为防止人为现象,胸部放置呼吸描记器并与压力换能器相连,记录呼吸运动。术后2周,53例患者同样方法再次测压,对照组是20例健康自愿者。
This article examines the relationship between anal canal pressure and very slow waves (USW’s) and the effects of internalisarticular excision (LIS) on pressure fluctuations. Anal canal pressure fluctuations are obvious, without considering the magnitude and frequency of fluctuations, fluctuations can be divided into slow wave, slow wave and spontaneous internal sphincter relaxation. Methods: Thirty patients with anal fissure and 20 patients with symptomatic hemorrhoids Ⅰ and Ⅱ who had no previous anorectal surgery were treated with LIS. Before the procedure, the catheter with transducer was inserted into the rectum to measure the rectal pressure of the anorectal tube, and the catheter was withdrawn at a constant speed of 2.5 mm / s. At the same time, the pressure curve was recorded. Repeat the test three times, then insert the catheter to find the highest rectal pressure, and in this position continued to record 30 minutes to observe the pressure changes. To prevent artifacts, place the plethysmograph on the chest and connect it to a pressure transducer to record respiratory motion. Two weeks after operation, 53 patients underwent the same method of retesting again, and the control group was 20 healthy volunteers.
