Wound Closure Methods for Scar Appearance
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores two methods of wound closure to determine which results in better-looking scars and fewer complications. It specifically compares intra-dermal (inside the skin) and transcutaneous (through the skin) purse-string sutures. Each participant will have a wound closed with both methods on different halves for comparison. Individuals scheduled for skin surgery on the head, neck, or limbs, who can return for a follow-up visit, might be suitable for this trial. As an unphased trial, it offers participants the chance to contribute to valuable research that could enhance wound care techniques.
Do I need to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that these wound closure methods are safe?
Research shows that both intra-dermal and transcutaneous purse-string closures are generally well-tolerated by patients.
For intra-dermal closures, studies indicate that this method usually results in good healing with minimal scarring. One study found infections to be rare. Another study noted that while some wounds reopened, poor skin quality, not the closure method, was the primary cause.
Transcutaneous closures also have a strong safety record. Research found no serious issues, such as infections or bleeding, with this method. It is often used to minimize scar size without affecting the final appearance.
Overall, both methods appear safe and effective for closing wounds, with few reported problems.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores two unique techniques for closing wounds with the goal of improving scar appearance. Unlike traditional sutures or staples, which can sometimes leave noticeable marks, the intra-dermal and transcutaneous purse-string closures distribute tension evenly across the wound. This could lead to a more aesthetically pleasing scar, as the techniques aim to minimize skin distortion and scarring. By comparing these two methods directly on opposite sides of the same wound, the trial hopes to determine which technique offers better cosmetic results.
What evidence suggests that these wound closure methods are effective for scar appearance?
This trial will compare two wound closure methods: intra-dermal purse-string closure and transcutaneous purse-string closure. Research has shown that both under-the-skin (intra-dermal) and through-the-skin (transcutaneous) stitching methods lead to similar cosmetic results. A 2015 study found that both techniques resulted in scars of similar size and pain levels. Another study observed good overall healing with under-the-skin stitching, with few issues like infection. Meanwhile, through-the-skin stitching has been linked to a lower risk of wound infection compared to other methods. Both techniques effectively close wounds, and complications are generally low, suggesting that both methods could improve the appearance of scars.12567

Are You a Good Fit for This Trial?
This trial is for individuals with scars who are undergoing surgery that requires wound closure. The study will compare two different stitching techniques to see which results in better-looking scars and fewer complications.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants undergo surgery with split-wound model using intra-dermal and transcutaneous purse-string closures
Follow-up
Participants are monitored for scar assessment and post-operative complications using POSAS and Trace-to-Tape methods
What Are the Treatments Tested in This Trial?
Interventions
- Intra-dermal purse-string closure
- Transcutaneous purse-string closure
Trial Overview
The study tests intra-dermal versus transcutaneous purse-string closures on wounds. Each patient's wound is split; one half gets the intra-dermal method, the other half gets the transcutaneous method. Scar appearance and any complications are assessed after three months.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
For all participants, one wound side half will be labeled as A and the other side as B. Side B will be closed with a intra-dermal purse-string closure, and Side A will be closed with a transcutaneous purse-string closure.
For all participants, one wound side half will be labeled as A and the other side as B. Side A will be closed with a intra-dermal purse-string closure, and Side B will be closed with a transcutaneous purse-string closure.
