Primary Closure of Pilonidal Sinus With Slide-Swing Skin Flap Compared With the Secondary Closure: A Single-Blinded...

Area of Science:

• Surgical Innovation
• Wound Healing
• Clinical Trials

Background:

• Pilonidal sinus disease (PSD) presents various surgical treatment options.
• Off-midline flaps are linked to reduced recurrence rates compared to midline closures.
• The study evaluates the slide-swing flap against secondary wound closure for PSD.

Purpose of the Study:

• To compare the short and long-term efficacy of the slide-swing flap technique versus conventional secondary wound closure for PSD.
• To assess outcomes including healing rates, cosmetic results, recovery time, and complication rates.

Main Methods:

• A prospective, single-blinded randomized controlled trial involving 100 patients with PSD.
• Patients were randomized into two groups: secondary closure (control) and slide-swing flap (trial).
• Post-operative follow-up included clinic visits twice weekly for two weeks, with a minimum six-month observation period.

Main Results:

• The slide-swing flap group showed significantly lower Visual Analog Scale (VAS) pain scores (p=0.006).
• The trial group experienced a higher healing rate, superior cosmetic outcomes, and quicker recovery.
• Operation time was longer for the slide-swing flap group (46.90 ± 7.81 min) compared to the control group (29.70 ± 7.71 min).

Conclusions:

• The slide-swing flap technique is superior to secondary closure for PSD regarding cosmetic outcomes, disease recurrence, and recovery.
• Post-operative complications were significantly reduced with the slide-swing flap.
• This flap technique offers an effective alternative for managing sacrococcygeal pilonidal sinus disease.
