Two treatments for fistula-in-ano were compared in a randomized trial. Times of healing were significantly shorter when the fistula was laid open (median 34 days, n = 26) than after excision (41 days, n = 21) (P less than 0.02). Revisional surgery was necessary before healing could be obtained in 3 of 26 patients after lay open operations and 2 of 21 after excision. Recurrence rates within 1 year were similar (3/24 and 2/21).
在一项随机试验中比较了两种肛瘘治疗方法。瘘管切开术（中位愈合时间34天，n = 26）后的愈合时间显著短于切除术（41天，n = 21）（P<0.02）。瘘管切开术后26例患者中有3例、切除术后21例患者中有2例在愈合前需要进行修复手术。1年内的复发率相似（24例中的3例和21例中的2例）。
