BACKGROUND Treatment of hemorrhoid disease is one of the most challenging fields in general surgery in which different methods are used to treat this condition. In this study, we compared the manometric and clinical results of three treatment methods for hemorrhoids. METHODS A total of 150 patients with symptomatic grades II or III internal hemorrhoids were randomly assigned to three groups. Group A underwent Ferguson hemorrhoidectomy, group B were treated with rubber band ligation (RBL) and group C were treated with direct current electrotherapy. RESULTS Preoperatively, grade III hemorrhoids had significantly higher mean resting pressure and mean squeezing pressure in comparison to grade II hemorrhoids. After hemorrhoidectomy, patients in group A had a significant decrease in the maximum resting pressure (90.8 to 77.7 mmHg) and maximum squeezing pressure (130.6 to 114.8 mmHg) with a significant raise in the volume of the first sensation. However there was no significant change in manometric indexes after RBL and electrotherapy. Group A patients had more postoperative pain and itching compared to groups B and C. CONCLUSION We conclude that electrotherapy is a safe, effective and simple method of treating grades II and III uncomplicated internal hemorrhoids. This procedure is associated with little postoperative pain and complications, and has the least changes in anorectal manometric characteristics. Therefore electrotherapy may be recommended as a treatment of choice for grades II and III uncomplicated internal hemorrhoids.
