Study summary

Infected pilonidal sinus is a common suppuration that occurs twice as often in men as in women, usually between the ages of 15 and 30. Clinical diagnosis is easy, whether the presentation is acute or chronic. Exeresis with a wound left open requiring secondary postoperative healing is the most widely practiced technique in France because its recurrence rate is the lowest, but it has the disadvantage of requiring daily or even twice-daily local nursing care, long healing, and a break in activity.

In order to limit the disadvantages of the open technique, "conservative" minimally invasive techniques have also recently been developed in response to strong patient demand: such as endoscopic treatment (EPSIT = Endoscopic Pilonidal Sinus Treatment, or VAAPS = Video-Assisted Ablation of Pilonidal Sinus), or the SiLaT (Sinus Laser Therapy) laser.

More recently, radiofrequency has emerged as a new technique in the treatment of hemorrhoidal pathology according to the Rafaelo procedure as well as the Fistura procedure for anal fistulas. The principle of the treatment is similar to that of the laser, based on radio frequency thermocoagulation using very high frequency electromagnetic waves (4MHz), similar to the principle of microwaves. However, its use in the infected pilonidal sinus has not yet been described. The fibers used in anal fistulas are perfectly adapted to the treatment of the pilonidal sinus. In addition, and in contrast to the laser, several fiber diameters are available depending on the size of the fistula path(s). For example, the large diameters of 9 Fr seem to be more adapted to the deep and wide cavities of the pilonidal sinuses than those of the SiLaT, which has a single fiber diameter. The investigators can therefore think that this type of fibers could allow a more efficient destruction of the granulation tissues and a better docking of the cavity walls.

According to published studies in the treatment of anal fistulas, the safety profile of this treatment is perfectly reassuring since the penetrance of the energy released does not exceed 3 mm in depth.

The aim of this study is to propose a competing alternative to the SiLaT laser, which is radiofrequency according to the Fistura® procedure, by evaluating its safety, efficacy and patient satisfaction on a series of consecutive patients treated

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • patient presenting an infected pilonidal sinus requiring an surgical procedure, at the exception of acute abscess stage
  • Patient aged 18 or above
  • For Women Of Child Bearing Age, use of efficient (less than 1% failure)
  • Patient with health insurance coverage
  • French-speaking patient
  • Signed written

Exclusion criteria

Exclusion Criteria:

  • Patient already included in a type 1 interventional research protocol (RIPH1)
  • Patient with cardiac disease (including pacemaker)
  • Patient with skin infection
  • Patient for whom local or general anesthesia is
  • patient presenting an anal infectious disease, or an anal fissure or who have previously had a stapled hemorrhoidopexy (Longo procedure) with metallic staples.
  • Patient using anticoagulant or anti- agent (at the exception of aspirin)
  • Patient suffering from innate hemostasis and/or coagulation disorder

  • Patient under legal protection
  • Patient refusing follow-up
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

What researchers measure

Primary outcomes

  1. Incidence rate of at least one complication of the surgery

    incidence rate of haemorrhagic complication or acute urinary retention or other complication (such as post surgery abcess, localized infection, haematoma)

    Time frame: Within 15days after surgery

Secondary outcomes

  1. Incidence rate of of haemorrhagic complication after surgery

    Time frame: Within 15days after surgery

  2. Incidence rate of acute urinary retention after surgery

    Time frame: Within 15days after surgery

  3. Incidence rate of other complication of surgery

    incidence rate of other complication such as post surgery abcess, localized infection, haematoma

    Time frame: Within 15days after surgery

  4. Evaluation of post-surgery pain

    Patient will be asked daily to evaluate post surgery pain using a Numerical Rating Scale (NRS). Patients will be asked to circle the number between 0 and 10 that fits best to their pain intensity. Zero represents 'no pain at all' whereas10 represents 'the worst pain ever possible'.

    Time frame: within 15 days post surgery

  5. Evaluation of radiofrequency treatment efficiency

    During the last patient visit, a clinical evaluation will be performed during which closure of all existing fistula external opening will be assessed (Yes or No), as well as the absence or presence of abcess and new external opening (Yes or no) . The patient will be asked to evaluate the presence or absence of pain (yes or no) The Treatment will be evaluated as efficient if there is closure of all fistula external opening AND absence of pain AND absence of abscess or new external opening

    Time frame: 6 months after surgery

  6. Length of the medical leave after surgery

    Record of number of medical leave days prescribed after surgery Record of number of day after surgery necessary before returning to normal activity.

    Time frame: within 6 months post surgery

  7. Measurement of patient satisfaction after surgery

    patient will evaluate their satisfaction regarding their surgery using a visual 5 point scale ranking from "very unsatified" to "very satisfied"

    Time frame: 1 month and 6 months post surgery

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

Ran from Jul 2023 to primary completion in Jan 2024, 6 months.

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 6 months is below that.

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 Mar 12, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
