Brief Summary

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).

Detailed Description

Pilonidal sinus disease (PSD) is an infectious or inflammatory condition beneath the skin at the peak of the gluteal cleft in the sacrococcygeal area. It is a chronic condition characterized by discharge, infection, and pain. Although it can occur during adolescence, it is most commonly seen in adult males, leading to a focus on adult treatments in research. Surgical treatment was first implemented by Anderson in 1847. Since then, various surgical and medical treatment options have been explored, yet there is no widely accepted standardized treatment. The ideal treatment should be simple, require a short hospital stay, have low recurrence rates, provide good cosmetic results, be cost-effective, cause minimal pain, and allow a quick return to social life, making the surgical approach contentious.

Maurice and Greenwood first reported the application of liquid phenol in 1964, initially under general anesthesia, later shifting to local anesthesia. Due to high recurrence rates with liquid phenol, Dogru and colleagues introduced the crystallized phenol (CP) procedure, a minimally invasive method now commonly used in adults.

Recent years have shown that stem cells and exosomes promote tissue healing and reduce inflammation. Known for their ability to differentiate into various cell types, stem cells, and exosomes play critical roles in intercellular communication, containing a variety of molecules. Their use in surgical fields has become popular as they speed up the post-operative healing process and reduce the risk of complications. Research in the literature supports that stem cells and exosomes accelerate wound healing (e.g., Nourian Dehkordi A, et al. 2019).

This study is based on two main premises: firstly, to identify the potential healing effects of stem cell and exosome applications in treating pilonidal sinus disease; and secondly, to comparatively assess the impact of these applications on surgical outcomes, specifically regarding surgery duration, complications, and the healing process. Comparing these two groups will help determine the value of stem cell and exosome applications in managing pilonidal sinus disease.

Primary Outcome Measures
NameTimeMethod
Average time to full daily activities1 week

It refers to the time when patients return to their routine lives after the procedure.

Recurrence rate7 weeks

The recurrence rate will be calculated after interventions

Wound healing time3 weeks

In the control group, the healing process generally takes about 2-3 weeks. In the experimental group, a shorter duration is expected. In this study, the wound healing times of both groups will be evaluated and compared.

Cosmetic results2 month

In this study, the worst healing wounds will receive a score of 1, and the best-healed wounds, which are closest to normal skin, will receive a score of 10. In short, a low score indicates poor wound healing and poor cosmetic, while a high score indicates that the wound has achieved a good cosmetic appearance.

Success rate7 weeks

The succes rate will be calculated after interventions

Skin burn rate2 weeks

In patients treated with crystallized phenol, skin burns can occur during application. To prevent this, Furacin ointment is applied around the wound. However, we still encounter skin burns. In this study, it is expected that the experimental groups will have a lower burn rate compared to the control group. The burn rate will be evaluated in this study.

VAS score7 weeks

Patient visual analog scale (VAS) scores will be assessed both prior to the procedure and again 10 days, 20 days following the procedure and after recovery.

Secondary Outcome Measures
NameTimeMethod
Bleeding rate1 week

Bleeding during interventions will be calculated

Infection rate7 week

Infection will be defined during interventions and 10 days after intervention

Total complication rate7 weeks

Total complicaitons during interventions will be calculated
