“Weight Control Following Body Contouring Surgery – Long-Term Assessment of Postbariatric and Non-bariatric Patients”

Abstract

Background: Few reports of weight maintenance following body contouring (BC) surgery present weight measurements as percentage weight change, and most of these studies do not isolate BC to specific body areas. This study analyzed weight control in the trunk-based BC population and further compared BC outcomes in postbariatric and nonbariatric patients. Methods: The authors performed a retrospective cohort study of consecutive postbariatric and nonbariatric patients who underwent trunk-based BC (abdominoplasty, panniculectomy, and circumferential lipectomy) from January 1, 2009, through July 31, 2020, at West Virginia University. A minimum 12-month follow-up was required for inclusion. With BC surgery date as the reference point, percentage total weight loss was assessed at 6-month intervals for 2 years following BC and every year thereafter. Change over time was compared between postbariatric and nonbariatric patients. Results: Within the 12-year timeframe, 121 patients meeting criteria underwent trunk-based BC. Average follow-up from date of BC was 42.9 months. Sixty patients (49.6%) had previously undergone bariatric surgery. From before BC to endpoint follow-up, postbariatric and nonbariatric patients experienced a 4.39% ± 10.93% and 0.25% ± 9.43% increase in weight from baseline, respectively (P = 0.0273). Once nadir weight loss was attained, weight regain occurred through endpoint follow-up in both groups (11.81% in the postbariatric cohort and 7.56% in the nonbariatric BC cohort; P = 0.0106). Conclusions: Long-term weight regain is common following trunk-based BC operations—specifically, in postbariatric patients. Although this should not contend with the psychological benefit of removing this excess tissue, it is important to report results with ideal weight metrics to optimally assess outcomes in this population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.
