Gedetailleerde beschrijving
This was a prospective, single-center, randomized, parallel-group comparative surgical study conducted at the Department of General Surgery, Kayseri City Training and Research Hospital, Türkiye. The study included adult patients aged 18 to 75 years with magnetic resonance imaging-confirmed transsphincteric anal fistula who met the eligibility criteria and provided written informed consent.
Participants were randomly assigned in a 1:1 ratio to undergo either standard ligation of the intersphincteric fistula tract (LIFT) or modified LIFT via a lateral approach. All patients were evaluated by the same surgical team, and postoperative follow-up was performed at weeks 1, 4, 8, and 12.
The study compared early clinical outcomes between the two procedures, including wound healing time, early recurrence or persistence, postoperative pain, and fecal continence. The study was approved by the Kayseri City Hospital Clinical Research Ethics Committee before patient enrollment.

Actieve vergelijker: Modified LIFT via a Lateral Approach
Participants assigned to this arm underwent modified LIFT via a lateral approach.
The fistula tract was approached from the external opening, dissected and mobilized toward the internal sphincter level, excised at this level, and the remaining defect and internal opening were closed while preserving sphincter integrity.

Actieve vergelijker: Standard LIFT
Participants assigned to this arm underwent standard ligation of the intersphincteric fistula tract (LIFT).
The intersphincteric plane was approached, and the fistula tract was identified, ligated, and divided according to the standard LIFT technique.

Early Recurrence or Persistence of Anal Fistula
Tijdsspanne: Postoperative weeks 1, 4, 8, and 12
|
Presence of persistent or recurrent fistula-related symptoms or clinical findings during postoperative follow-up.

Postoperative Pain Assessed Using the Visual Analog Scale
Tijdsspanne: Postoperative weeks 1, 4, 8, and 12
|
Postoperative pain will be assessed using the Visual Analog Scale.
The score ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
Higher scores indicate worse pain.

Fecal Continence Assessed Using the Wexner Fecal Incontinence Score
Tijdsspanne: Postoperative weeks 1, 4, 8, and 12
|
Fecal continence will be assessed using the Wexner Fecal Incontinence Score.
The score ranges from 0 to 20, where 0 indicates perfect continence and 20 indicates complete fecal incontinence.
Higher scores indicate worse continence.
