Effect of Antiseptic Irrigations With 0.05% Chlorhexidine Gluconate (Irrisept) Versus Normal Saline on Fasciocutaneous Flap-Based Closure of Pilonidal Disease

Pilonidal disease is a chronic condition that causes painful inflammation and infection near the top of the buttocks. Many patients require surgery, and one commonly used approach is a bilateral gluteal fasciocutaneous flap with midline closure along with placement of an extracellular matrix to support wound healing. Although effective, this surgery can still lead to wound problems such as infection, fluid collection (seroma), wound separation (dehiscence), and delayed healing. This study aims to compare two different solutions used to rinse the surgical wound before closing it. One solution is Irrisept, which contains 0.05% chlorhexidine gluconate, an antiseptic designed to reduce bacteria. The other is normal saline, which is the current standard rinse used in surgery. The goal is to determine whether using Irrisept can safely reduce post-operative infections and wound-related complications in patients undergoing flap closure and extracellular matrix implantation for pilonidal disease.

Topical Anti-Androgens in Pilonidal Sinus Disease

The goal of this randomized clinical trial is to test the topical drug clascoterone in patients with pilonidal disease, which is a common, benign skin condition of the gluteal cleft. The main questions it aims to answer are: * Does clascoterone improve the severity of pilonidal disease as scored by a physician? * Does clascoterone improve patient symptoms due to pilonidal disease? * Does clascoterone improve the inflammation seen under the microscope in pilonidal disease removed at surgery Participants will apply clascoterone or a placebo cream to the diseased area for 3 months. They will be assessed every 4 weeks for disease severity assessed by a physician viewing patient photos and a symptom-based survey. Researchers will compare participants who received clascoterone treatment to those who received placebo.

Intraoperative Wound Irrigation for Pilonidal Disease

The purpose of this study is to determine the best method for cleaning wounds during surgery for patients with Stage 3 pilonidal disease. The investigators will compare the standard wound cleaning solution, saline, with a different solution called hypochlorous acid (Vashe, Urgo Medical) to see which one helps wounds heal faster after surgery.

Pilot Trial Assessing the Effectiveness of Laser Hair Depilation on Pilonidal Disease Recurrence in Patients With Darker Skin Color

A Trial in Mini-invasive Pilonidal Sinus Disease Surgery

Pilonidal sinus disease is a chronic acquired disease leading to significant morbidity and healthcare costs in young man and women. Despite different treatment methods, the disease relatively often leads to postoperative complications and recurrence.(8). Advantages of mini-invasive techniques include: quicker recovery and earlier return to work and high patient satisfaction. Randomized studies are rare and this applies especially to newer mini-invasive techniques. The purpose of the investigators prospective study is to randomly compare the mini-invasive laser ablation technique to the mini-invasive fibrin glue treatment in pilonidal sinus disease surgery.

Comparing Operative vs Non Operative Treatment for Pilonidal Disease

The goal is to evaluate whether surgical excision of the pilonidal disease is needed after resolution of the initial symptoms when the patient follows regular hair removal regimen such as laser epilation.

Comparing Minimally Invasive Treatments for Pilonidal Disease: LA POPA Trial (Laser And Pit-picking OR Pit-picking Alone)

The goal of this randomized clinical trial is to establish the efficacy of 'pit picking with laser therapy' versus 'pit picking alone' on both short and long-term outcomes in patients of 12 years and older with primary pilonidal sinus disease. The main questions it aims to answer are: * The overall success rate of treatment which is defined as: closure of all pits at 12 months of follow-up. * Secondary endpoints: succes rat eof treatment during long-term follow-up, wound closure time, pain scores, complication rate, work rehabilitation, time to return to daily activities, quality of life, persisting complaints, patient satisfaction, costs and the need for secondary or revision surgery. Participants will allocated to pit picking alone or combined with lasertherapy. The extra burden for participating patients is expected to be minimal to moderate. Participants will have two extra hospital visits in casethey are enrolled in our study: 6 and 12 months after enrolment. Postoperatively the normal scheme of follow up appointments wil be used: 2 and 6 weeks after treatment at the outpatient clinic of the treating surgeon. A telephone appointment with the researcher will be scheduled 4 weeks after treatment. Patients are asked to complete questionnaires at various time points, which will be sentto them by email and will take approximately 5-10 minutes each time. The content includes general and disease specific Quality of Life (QoL) questionnaires. The investigators do not expect any extra adverse reactions or events in respect to participation in the study because both procedures are considered standard of care in the participating clinics. However, because both interventions are surgical procedures a small percentage of adverse events or postoperative complications can be expected.

The Role of Mesenchymal Stem Cell and Exosome in Treating Pilonidal Sinus Disease in Children

Chronic wounds that fail to heal over extended periods pose a significant financial burden on the healthcare system, underscoring the urgent need to enhance clinical treatments. Among the most promising approaches are stem cell-based therapies. Substantial evidence suggests that mesenchymal stem cells (MSCs) can facilitate the healing of chronic wounds in both animal models and preclinical studies, primarily through their paracrine actions. The bioactive factors and cytokines secreted by MSCs can be harvested in the form of conditioned medium. This medium has been processed into a lyophilized powder for clinical use. Patients with chronic wounds will recruited and divided into two groups: the control group will receive the commonly used fibroblast growth factor, while the experimental group was treated with the lyophilized powder. The study aims to assess the efficacy and safety of this Stem cell and exosome in treating chronic wounds (especially pilonidal sinus).

MIPE for Pilonidal Disease

Pilonidal disease often presents as a chronic, relapsing condition. A variety of procedures are used in the management of pilonidal disease, with varying degrees of morbidity, disease-free interval, and long-term success. In patients with new-onset or recurrent pilonidal disease, the investigators aim to address how minimally invasive trephine excision compares to other surgical procedures in terms of short- and long-term clinical outcomes and patient satisfaction. In the absence of a gold standard surgical procedure, surgeon preference will help dictate the management of pilonidal disease. For many surgeons, this means a variation on open excision for pilonidal disease failing conservative management. However, outcomes for minimally invasive pilonidal excision (MIPE) as initially described by Gips and forthcoming Lipskar et al., are likely to alter management of the disease (Gips, 2008). The investigators wish to assess patient and surgeon satisfaction with MIPE, and short-term outcomes.
