Fast- vs slow-absorbing sutures in ultra tension-reducing closure

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-center, evaluator-blinded, self-controlled trial in the plastic surgery department at The Second Hospital of Lanzhou University. Each participant receives both suture types on matched wound segments within the same incision: slow-absorbing PDS on Segment A and fast-absorbing Vicryl on Segment B, with standardized closure techniques and postoperative care. Follow-up visits occur at 1 week, 1 month, and 3 months to assess scar formation and healing. The study aims to clarify whether sustained dermal support from slower-absorbing sutures improves hypertrophic scar prevention under ultra tension-reducing closure. Eligible participants have clean incisions of at least 5 cm and are scheduled for dermatologic linear wound closure.
