Retrospective Evaluation of the Safety of Large Skin Flap, Large Skin Graft, and Interpolation Flap Surgery in the Outpatient Setting

BACKGROUND As the number of cutaneous surgeries continues to increase, it is important to evaluate the safety of dermatologic surgery in the outpatient setting. OBJECTIVE The authors sought to determine postoperative bleeding, infection, dehiscence, and necrosis rates in office-based dermatologic surgery using large flap, large graft, and interpolation flap repairs. The authors evaluated the relationship between these complications and surgical site, closure type, repair size, antibiotic use, and antithrombotic use. METHODS Eligible patients were identified through searching the electronic medical records from one Mohs micrographic surgeon at University Hospitals Medical Center. Patient information, surgery characteristics, and complication information were collected. Univariate and multivariate analyses were conducted to reveal associations between each complication and closure type, repair size, repair site, antithrombotic use, and antibiotic use. RESULTS Three hundred and thirty-one reconstruction procedures after Mohs micrographic surgery and excision qualified for the study. The rates of postoperative infection, hemorrhage, hematoma, necrosis, and dehiscence were 5%, 0.3%, 2.4%, 3%, and 0.9%, respectively. CONCLUSION Complications were infrequent and non–life-threatening. The authors' results indicate that dermatologic surgery using large flaps, interpolation flaps, and large grafts is safe in the office setting.
