Thirty-eight patients with condylomata acuminata of the anus, requiring surgical therapy, had the left half of the anus treated with conventional electrical cautery, while the right half of the anus was treated with the carbon dioxide laser at the same time. Patients were questioned about the amount of pain on both sides and were studied for evidence of recurrence. The laser was associated with either more pain or the same amount of pain when compared with that of electrical cautery. Recurrences were first seen more often on the laser side. The cost of the laser treatment to the patient was higher by $50. it is concluded that the laser offers no advantage and may, indeed, be less effective than the conventional electrical cautery in the treatment of condylomata acuminata of the anus.
38例需要手术治疗的肛门尖锐湿疣患者，肛门左侧采用传统电灼治疗，同时肛门右侧采用二氧化碳激光治疗。询问患者两侧的疼痛程度，并研究复发证据。与电灼相比，激光治疗时疼痛更多或疼痛程度相同。激光治疗侧复发首次出现的情况更常见。激光治疗对患者的费用高出50美元。得出的结论是，在治疗肛门尖锐湿疣方面，激光没有优势，实际上可能比传统电灼效果更差。
