In this issue of JAMA Dermatology, Joo and colleagues1 report the results of a randomized clinical trial (RCT) comparing purse-string suture closure to secondary intention healing for wounds on the trunk and extremities. By rigorously examining a commonly used dermatologic procedure, their work has the potential to immediately impact the daily practice of dermatologists. The purse-string suture has been used to repair cutaneous defects for nearly 3 decades.2 Indeed, the purse-string repair has been noted by numerous authors to improve cosmesis, reduce scar size, speed healing, and minimize complications compared with secondary intention healing.3-6
