About

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.

Full 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.

Characteristic data

1. Age, Gender, ASA class,
2. Past history: medical history, surgical history
3. Previous anorectal history
