Lateral Advancement Flap Versus Classic Limberg Flap in The Treatment Of NonComplicated Pilonidal Sinus
Condition: Pilonidal Sinus
MeSH terms: Pilonidal Sinus
Study type: Interventional

Summary: 
      Background The flaps closure including natal cleft obliteration and eccentric closure are
      becoming more popular due to their lower rate of recurrence including both the lateral
      advancement adipo-fascio-cutaneous flap and the classic limberg flap.

      Objective This study was aim to compare the results of the surgery for non-complicated
      pilonidal sinus with the lateral advancement adipo-fascio-cutaneous flap versus the classic
      Limberg flap.

      Patients and methods This study was a prospective randomized controlled, and was conducted on
      patients with non-complicated pilonidal sinus attending Zagazig University Hospitals, Egypt
      during the period from February 2017 to August 2019. Patients were randomly assigned to
      undergo either lateral advancement flap or classic Limberg flap groups. The follow-up period
      ranged from 12 to 36 months. Patient satisfaction, complications and recurrence rates were
      analyzed and compared.
    

Detailed description: 
      Hodges was the first to use the term "pilonidal" (which was derived from the Latin pilus=hair
      and nidus=nest) in 1988.

      The pilonidal disease is usually predisposed by the presence of a deep natal cleft containing
      a lot of hairs within it, which is also supplies a good environment for maceration, sweating,
      hairs penetration, and bacterial contamination . A lot of surgical treatment techniques are
      described for pilonidal sinus disease as simple excision and packing, excision with primary
      midline closure, marsupialization and eccentric closure by different types of flaps.

      Though no surgical technique has been widely accepted, but the flaps closure including natal
      cleft obliteration and eccentric closure are becoming more popular due to their lower rate of
      recurrence.

      Although the off-midline approach seems optimal for closure, the standard off-midline surgery
      has not yet been concluded.

      According to our best knowledge, no randomized study has yet compared the lateral advancement
      adipo-fascio-cutaneous flap and the classic Limberg flap. Therefore, the aim of the present
      study was to compare in a randomized controlled trial the short-term results of the surgical
      treatment of non-complicated pilonidal sinus with the lateral advancement
      adipo-fascio-cutaneous flap versus the classic Limberg flap.
