Operating time and cost analysis for open hemorrhoidectomy
Of the 58 patients included in this trial, 29 participants per group of anesthesia were considered. The operating time and hospital stay were significantly shorter in group A compared to group B (p < 0.001). The cost of OH was significantly lower in group A compared to group B (p = 0.04) (Table
