The Constriction Arm Band Deformity in Brachioplasty Patients: Characterization and Incidence Using a Prospective Registry

Complications Following Body Contouring: Performance Validation of Bard, a Novel AI Large Language Model, in Triaging and Managing Postoperative Patient Concerns

INTRODUCTION

Large language models (LLM) have revolutionized the way humans interact with artificial intelligence (AI) technology, with marked potential for applications in esthetic surgery. The present study evaluates the performance of Bard, a novel LLM, in identifying and managing postoperative patient concerns for complications following body contouring surgery.

METHODS

The American Society of Plastic Surgeons' website was queried to identify and simulate all potential postoperative complications following body contouring across different acuities and severity. Bard's accuracy was assessed in providing a differential diagnosis, soliciting a history, suggesting a most-likely diagnosis, appropriate disposition, treatments/interventions to begin from home, and red-flag signs/symptoms indicating deterioration, or requiring urgent emergency department (ED) presentation.

RESULTS

Twenty-two simulated body contouring complications were examined. Overall, Bard demonstrated a 59% accuracy in listing relevant diagnoses on its differentials, with a 52% incidence of incorrect or misleading diagnoses. Following history-taking, Bard demonstrated an overall accuracy of 44% in identifying the most-likely diagnosis, and a 55% accuracy in suggesting the indicated medical dispositions. Helpful treatments/interventions to begin from home were suggested with a 40% accuracy, whereas red-flag signs/symptoms, indicating deterioration, were shared with a 48% accuracy. A detailed analysis of performance, stratified according to latency of postoperative presentation (<48hours, 48hours-1month, or >1month postoperatively), and according to acuity and indicated medical disposition, is presented herein.

CONCLUSIONS

Despite promising potential of LLMs and AI in healthcare-related applications, Bard's performance in the present study significantly falls short of accepted clinical standards, thus indicating a need for further research and development prior to adoption.

A Personal Approach to Brachioplasty

ABSTRACT

Brachioplasty has become one of the fastest-growing aesthetic surgery procedures, paralleling rising rates of weight loss surgery nationally. However, controversy persists regarding incision placement and utility of concurrent liposuction. In this article, the authors describe indications, patient selection, expected outcomes, and photographic standards for patients seeking brachioplasty after weight loss. Preoperative markings, scar placement, and operative steps of a posterior incision technique with or without concurrent liposuction if indicated are described. A personal experience with posterior incision brachioplasty along with current controversies, complications, and patient-reported outcomes after upper arm contouring are reviewed.
