简要总结
This clinical trial studies whether a disposable negative pressure wound therapy (dNPWT) device, SNaP Wound Care System (Ultraportable Mechanically Powered Negative Pressure Wound Therapy) (SNaP), promotes wound healing in the lower limbs in patients that have undergone Mohs micrographic surgery (Mohs surgery) for non-melanoma skin cancer. Mohs surgery is a surgical technique used to treat skin cancer. Individual layers of cancerous tissue are removed and examined under a microscope one at a time until all cancerous tissue has been removed. It is an important part of removing skin cancer, but it often leads to soft-tissue defects and reconstructive challenges, especially in high-tension areas like the lower limbs. Typically, these wounds are managed by leaving them open and allowing them to heal from the base up or are reconstructed by transferring healthy skin from another part of the body. Negative pressure wound therapy (NPWT) is a wound dressing system that continuously or intermittently applies subatmospheric pressure to the surface of a wound to draw out fluid and promote healing. The SNaP device is a dNPWT device for lower leg wound healing designed for increased portability and ease of use outside of a hospital setting. It is a modification of traditional NPWT devices that uses springs to generate pressure, making it lighter and more user-friendly than traditional devices that rely on electrically powered pumps. This may be a more effective way to promote wound healing in the lower limbs following Mohs surgery for non-melanoma skin cancer.
详细描述
PRIMARY OBJECTIVE:
I. To compare wound healing duration between the two groups, aiming to provide insights into the potential benefits of dNPWT for lower limb wounds in a clinical setting.
OUTLINE: Patients are randomized to 1 of 2 groups.
GROUP 1: Patients undergo dNPWT with SNaP device following standard of care (SOC) Mohs surgery and attend follow-up visits with re-application of SNaP device over 30 minutes once a week (QW), as needed until complete wound healing is achieved, for up to 12 weeks. Patients also receive education regarding SNaP device application and informational/educational SNaP device handouts on study.
GROUP 2: Patients undergo SOC wound care with non-adherent dressing following SOC Mohs surgery and attend follow-up visits with non-adherent dressing changes over 30 minutes QW, as needed until complete wound healing is achieved, for up to 12 weeks. Patients also receive education on SOC wound dressing changes on study.

结局指标
主要结局
Wound healing duration
时间窗: Up to 12 weeks
Will be defined as the number of days from surgery to complete wound closure (full re-epithelialization), assessed during follow-up visits. Will be analyzed as a time-to-event variable. To compare the time to wound closure between the SNaP Wound Care System (Ultraportable Mechanically Powered Negative Pressure Wound Therapy) (SNaP) device and standard care groups, Kaplan-Meier survival curves will be generated, which will visually illustrate whether the SNaP device accelerates wound healing. The log-rank test will be used to formally assess whether the difference in healing times between the two groups is statistically significant or if any differences observed could have arisen by random chance. Additionally, a Multivariable Cox proportional hazards model will be employed to adjust for potential confounders (e.g., wound size, patient age, and comorbidities).
次要结局
- Mean time to wound closure(Up to 12 weeks)
- Patient satisfaction(At 12 weeks)
- Wound size progression(Up to 12 weeks)
- Cosmetic outcomes(At 12 weeks)
