Study summary

Pilonidal Disease is disease of young patients with significant morbidity and is difficult to treat. Currently multiple methods are practiced for the treatment of the disease, two of them are preferred over others and practice extensively. First one involves excision of pilonidal sinus and dressings while the second one is excision of the pilonidal sinus with application of negative pressure wound therapy. None of these approaches is considered superior to the other, as not enough comparison studies of the two procedures have been done. In order to clarify this and find the best option for our patients, investigators are taking opportunity to compare these two modalities. If participants choose to participate in this study they will be randomly selected to one of these groups and the progress of wound healing will be monitored after surgery with the measurement of wound weekly and photographs. Investigators are hoping to find out which procedure is superior. This will allow investigators to provide the best treatment option for their patients in future.

What researchers measure

Primary outcomes

  1. Time to complete wound healing

    Time between Surgery and complete healing when there is no further requirement to apply dressing

    Time frame: Wound will be assessed for healing at 1 week to 6 weeks

Secondary outcomes

  1. VAS score (Visual Analogue Scale)

    Pain score as scored by patients, VAS is an analogue scale is from 1 to 10, 1 being minimal discomfort to 10 being the worst pain in the life

    Time frame: VAS for pain will be recorded at 1 week to 6 weeks at weekly intervals

  2. Wound size ratio

    Healing as ratio of the initial wound

    Time frame: Wound size ratio will be recorded at 1 week to 6 weeks at weekly intervals

  3. Time to resume daily activities

    Time at which patient is able to do his/her daily household works

    Time frame: Assessment will be done at 1 week to 6 weeks at weekly intervals

  4. Recurrence

    Recurrence of disease at 6 months from surgery

    Time frame: Patient will be assessed at 6 months from surgery

  5. Analgesia Requirement

    Requirement for analgesia will be recorded to make the pain analysis more robust

    Time frame: Recording will be done at 1 week to 6 weeks at weekly intervals

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2018 (actual). Primary completion is estimated for Oct 2019, 17 months after the start.

Of 35 interventional studies with no phase under Pilonidal Sinus, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 35. This study's planned 17 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 5, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
