Study population: Benign anorectal disease patients underwent surgery interventions. Characteristics of age, gender, height, weight, ASA score, past medical history, operational history were recorded from EHIS systems. Intraoperative findings which include anesthesia time, operation time, intraoperative fluid. Surgical outcomes include surgery complications, anesthesia complications, pain score. All of above data were retrospective recorded from hospital discharge note, OPD records, operation note, pathology report.

Brief summary: Anorectal surgery includes pilonidal sinus, hemorrhoidectomy, anal fissure, and anal fistula operations. General and spinal anesthesia were common anesthetic methods in anorectal surgery. We designed this study to test the hypothesis that general anesthesia was superior than spinal anesthesia with respect to urine retention rate, pain score, recovery time, and side effects.

Detailed description: Anorectal surgery includes pilonidal sinus, hemorrhoidectomy, anal fissure, and anal fistula operations. Deep level of anesthesia is required for these surgeries. Excellent operation conditions and rapid recovery is anticipated for optimal anesthesia. Various surgical and anesthetic techniques, including spinal anesthesia, general anesthesia and local infiltration have been used to increase the level of patients' perioperative analgesia and decrease the length of stay in the hospital. Among them, general and spinal anesthesia were common anesthetic methods in anorectal surgery. We designed this study to test the hypothesis that general anesthesia was superior than spinal anesthesia with respect to urine retention rate, pain score, recovery time, and side effects.
