Non-Powered Negative Pressure Wound Therapy vs Open Technique for Pilonidal Disease (NPWTvsOT)

April 4, 2019 updated by: Yasir Bashir, The National Children's Hospital, Tallaght

Randomized Controlled Trial of Non-Powered Negative Pressure Wound Therapy vs Open Technique for Pilonidal Disease

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
32

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to complete wound healing
Time Frame: Wound will be assessed for healing at 1 week to 6 weeks
Time between Surgery and complete healing when there is no further requirement to apply dressing
Wound will be assessed for healing at 1 week to 6 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
VAS score (Visual Analogue Scale)
Time Frame: VAS for pain will be recorded at 1 week to 6 weeks at weekly intervals
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
VAS for pain will be recorded at 1 week to 6 weeks at weekly intervals
Wound size ratio
Time Frame: Wound size ratio will be recorded at 1 week to 6 weeks at weekly intervals
Healing as ratio of the initial wound
Wound size ratio will be recorded at 1 week to 6 weeks at weekly intervals
Time to resume daily activities
Time Frame: Assessment will be done at 1 week to 6 weeks at weekly intervals
Time at which patient is able to do his/her daily household works
Assessment will be done at 1 week to 6 weeks at weekly intervals
Recurrence
Time Frame: Patient will be assessed at 6 months from surgery
Recurrence of disease at 6 months from surgery
Patient will be assessed at 6 months from surgery
Analgesia Requirement
Time Frame: Recording will be done at 1 week to 6 weeks at weekly intervals
Requirement for analgesia will be recorded to make the pain analysis more robust
Recording will be done at 1 week to 6 weeks at weekly intervals

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
