There is no consensus on the ideal anesthesia for hemorrhoidectomy in ambulatory facilities. Spinal anesthesia and venous propofol associated with local perianal block (combined anesthesia) are frequently used, and their direct costs may be crucial for the anesthesia type selection. The objective of this study was to compare the direct costs of anesthesia-related materials in hemorrhoidectomy between these two anesthetic techniques.Retrospective and cross-section analysis, comparing the direct costs of the materials of spinal and venous anesthesia with propofol associated with local perianal block, in hemorrhoidectomy. Twenty patients were included, ten submitted to each anesthesia type (five from each gender). The mean age in the spinal anesthesia group was 46.5 years and in the combined anesthesia group, 42.5 years (p=0.334). The mean cost of anesthesia-related materials was R$ 58.50 (R$ 36.48 - R$ 85.79) in the first group versus R$ 190.31 (R$ 98.16 - R$ 358.51) in the second - 69.27% difference between them (p<0.001). The mean costs according to gender analysis were R$ 50.32 and R$ 66.69 (p=0.263) in the spinal anesthesia group versus R$ 222.52 and R$ 158.10 (p=0.221) in the combined anesthesia group, respectively. The direct costs of anesthesia-related materials were significantly lower in patients submitted to hemorrhoidectomy using spinal anesthesia. No difference was observed between the genders in each group analyzed.
