Complications Post Abdominoplasty After Surgical Versus Non-surgical Massive Weight Loss: a Comparative Study.

[PURPOSE] This study aims to investigate the rate of short- and long-term complications as well as the need for operative revisions after abdominoplasty for patients following surgical versus non-surgical weight loss methods.

[METHODS] This is a retrospective chart review that enrolled consecutive patients undergoing abdominoplasty across a 5-year period, aged 18 years and above, opting for abdominoplasty after weight loss achieved through bariatric surgery or diet and exercise alone.

[RESULTS] A total of 364 patients lost weight through bariatric surgery and 106 by diet and exercise alone. There were no significant differences in comorbidity status, but past body mass index (BMI) was higher for the surgical weight loss (SW) group (47.6 ± 10.2 and 40.4 ± 8.6, respectively; p value < 0.0001). Percent excess weight loss (EWL) was 68 ± 14.5 for the SW group and 55.7 ± 19.4 for the NSW group, p value < 0.0001. Pre- and postoperative blood hemoglobin levels were significantly lower in the SW group (p < 0.05). Neither short-term complications (thromboembolic events, wound complications, or infections) nor long-term complications (umbilical deformity, delayed wound healing, or infection) and operative revisions were significantly different across both groups (p > .05).

[CONCLUSION] Bariatric surgery does not increase the risk of short- or long-term complications or the need for operative revision after abdominoplasty.
