More than 90% of anorectal surgery can be done in an outpatient setting. The savings for anorectal procedures in 1982 for inpatient room cost alone could have been almost $200 million. The use of local anesthesia for anorectal surgery enhances patient safety. Ambulatory surgery should be considered whenever anorectal procedures are contemplated.
超过90%的肛肠手术可在门诊进行。仅1982年肛肠手术节省的住院病房费用就可能接近2亿美元。肛肠手术使用局部麻醉可提高患者安全性。每当考虑进行肛肠手术时，都应考虑门诊手术。
