摘要
Background An initial study enabled us to achieve 60% healing of high transsphincteric fistula-in-ano with laser ablation of fistula tract (LAFT) The purpose of this new study was to investigate other predictors of the success of this technique in the treatment of complex anoperineal fistulas. Methods All patients treated with LAFT in our department between May 2017 and October 2018 were included prospectively. LAFT was used for patients with complex anoperineal fistulas who were at high risk of anal incontinence after fistulotomy. The fistula was considered healed when the internal and external openings were closed and the patient experienced no pain or leakage. Results A total of 100 consecutive patients (65 males) with a median age of 43 years (range 22-88 years) were included in the study. Eight patients were lost to follow-up. The fistulas were low (8%) or high (79%) transsphincteric, and suprasphincteric (13%). After a median follow-up of 13.6 months (range 6-23 months), fistula healing was observed in 41 patients (44.6%). On univariate analysis, an anterior location, a narrow internal orifice and administration of less than 400 J of energy were significantly associated with healing. On multivariate analysis, a narrow internal orifice and low energy administration remained significant predictive factors of success [OR 5.08 (1.03-25.03), p = 0.046; OR 2.59 (1.08-6.17), p = 0.032]. No new cases of anal incontinence or any worsening of pre-existing anal incontinence was observed during follow up. Conclusions This study indicates that complex anoperineal fistulas with a narrow internal orifice can be successfully treated with less than 400 J and are ideal for LAFT.
