One hundred and two patients with a pilonidal sinus treated by minor excision had a life-table of 5-year freedom from recurrence of 89% provided that they attended a dressing clinic until the wound healed. With failure to attend the clinic, the recurrence freedom fell to 57% (P less than 0.004). Age, sex, acute abscess, previous excision, presence of hairs and the number of midline pits and lateral abscesses did not significantly influence the result. The method supersedes more extensive procedures, but should be tested against even less traumatic techniques.
102例采用小切口切除术治疗的藏毛窦患者，若他们前往换药门诊直至伤口愈合，其5年无复发生存率为89%。若未前往门诊，无复发生存率降至57%（P<0.004）。年龄、性别、急性脓肿、既往切除术、毛发存在情况、中线窦口数量及外侧脓肿数量对结果均无显著影响。该方法取代了更为广泛的手术，但应与创伤更小的技术进行对比验证。
