Brief Summary

Postoperative recurrent pilonidal sinus disease is troublesome and its treatment is challenge. Many treatment modalities have been advocated in the treatment of recurrent pilonidal sinus disease; however, there is still no consensus in the literature. Some minimally invasive techniques are used alone or as an adjunct to surgery. Crystallized phenol is the most popular method in the nonoperative treatment of primer pilonidal sinus disease. But its long term effect in the postoperative recurrent cases is unclear. Investigators aimed to present the long-term efficacy of crystallized phenol treatment on postoperative recurrent pilonidal sinus disease through our results collected within the last 20 years.

Outcome Measures

Primary Outcomes (1)

  • Long term effect of crystallized phenol treatment in recurrent pilonidal sinus

    All participants we applied to crystallized phenol treatment (CPT) were contacted via e-mail, telephone or face-to-face interview and questioned whether there was a recurrence. The number of CPT applications and sinus characteristics (primer openings, seconder openings, sinus presentation etc.) were compared between recurrent participants and non-recurrent participants. The number of CPT application and sinus characteristic features was obtained patients files that were recorded in first consult.

    January 1995-February 2015

Secondary Outcomes (1)

  • The effects of factors playing a role in the etiology of pilonidal sinus on treatment results

    January 1995-February 2016

Study Arms (1)

Recurrent pilonidal sinus

Postoperative recurrent pilonidal sinus disease

Procedure: Crystallized phenol treatment

  • Previous operated recurrent pilonidal sinus disease
  • Follow-up period of more than 12 months
  • The patients who connection by e-mail or telephone

You may not qualify if:

  • Primer pilonidal sinus disease
  • Follow-up period of less than 12 months
