Comparing suture types for better scar outcomes in patients with skin of color

Impact of Suture Type on Pigment Disturbances in Patients of Skin of Color: A Prospective, Randomized Split-wound Study

Not applicable Interventional University of Pittsburgh · NCT05408117

This study is testing whether dissolvable or non-dissolvable stitches lead to better-looking scars for patients with skin of color after surgery.

What this trial studies

This study evaluates the impact of two types of sutures—dissolvable (fast gut) and non-dissolvable (polypropylene)—on cosmetic results related to scarring and dyspigmentation in patients with skin of color. Participants undergoing standard elliptical excisions will have their wounds divided into two halves, each receiving a different suture type. Measurements of scarring and pigment changes will be taken at various intervals post-surgery. The study aims to determine which suture type yields better aesthetic outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with skin of color (NIS skin color 4 or greater) who require dermatologic surgery with a wound length of 3 cm or more.

Not a fit: Patients with high-tension closures, known allergies to suture materials, or those who are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved cosmetic results and reduced pigment disturbances for patients with skin of color undergoing dermatologic surgery.

How similar studies have performed: While the specific approach of comparing these suture types in patients of skin color is novel, similar studies have shown varying success in optimizing surgical outcomes based on suture materials.

Eligibility criteria

Inclusion Criteria:

1. Age 18 years or older
2. Undergoing dermatologic surgery with planned standard elliptical excision with wound length of 3 cm or greater. Benign and malignant lesions will be included, including those that have undergone Mohs micrographic surgery prior to standard linear closure. All body sites will be included.
3. Able to give informed consent
4. Able to return for 3 month follow up
5. New Immigration Scale (NIS) skin color 4 or greater - The NIS is an 11 point scale, ranging from zero to 10, with zero representing albinism and 10 representing the darkest possible skin.

Exclusion Criteria:

1. High-tension closures not amenable to 5-0 simple running epidermal sutures
2. Known allergy to suture material
