Purse-string suture vs second intention healing: results of a randomized, blind clinical trial.

Importance: Purse-string suture is a closure method that purportedly reduces the scar area compared with second intention healing. Randomized clinical trials comparing these 2 methods appear to be limited or absent.

Objective: To determine if purse-string suture improves cosmetic outcome, healing time, and scar to defect area compared with second intention healing for circular defects on the trunk and extremities.
