Study Type Interventional
Study Design Allocation: Randomized;   Intervention Model: Single Group Assignment;   Masking: Single (Outcomes Assessor);   Primary Purpose: Other
Condition Cutaneous Sutures and Scar Cosmesis
Intervention Device: Fast absorbing gut suture
Enrollment 50
Recruitment Details This randomized clinical trial was conducted at the University of California, Davis dermatology clinic from November 28, 2017, to June 15, 2018.
Pre-assignment Details  
Arm/Group Title All Participants
Hide Arm/Group Description A split wound model was used, where half of the wound was repaired with sutures placed 2 millimeters apart and the other half is repaired with sutures placed 5 millimeters apart. A predetermined, concealed randomization number was obtained from the RedCap randomization module, which specified how Side A was treated. Side B was treated the opposite way as A.
Period Title: Overall Study

Completed 48
Not Completed 2
Arm/Group Title Fast Absorbing Gut Suture Placed 2 mm and 5 Mmapart
Hide Arm/Group Description

Wound closed with sutures spaced 2 and 5 millimeters apart will be treated in a simple, interrupted cutaneous suture pattern

Fast absorbing gut suture: Fast absorbing surgical gut suture is a strand of collagenous material

1.Primary Outcome
Title Patient Posas Score
Hide Description Scale name: Patient Observer Scar Assessment Score. Scale measures six parameters of scars, each using a 10-point scoring system (the six categories are summed to achieve the POSAS score - totals range from 6 to 60), with 1 representing normal skin & 10 representing the most severe scar imaginable.
Time Frame 3 months following procedure
