The advantages of cryosurgery over resection techniques in treating perianal fistulae include low recurrence rate, low incidence of incontinence, ease of performance, the relatively short amount of time required for the procedure, and minimal blood loss. If the disease is diagnosed and treated early in its course, complete resolution may be expected after one cryosurgical procedure. However several months and more than one surgical procedure are sometimes required in severe cases. The prognosis is good to excellent, depending on the stage and severity of the disease.
在治疗肛周瘘管方面，冷冻手术相较于切除技术的优势包括复发率低、失禁发生率低、操作简便、手术所需时间相对较短以及出血量极少。如果疾病在病程早期得到诊断和治疗，一次冷冻手术治疗后有望实现完全治愈。然而，在严重病例中，有时需要数月时间且不止一次手术。根据疾病的阶段和严重程度，预后良好至极佳。
