Abstract Background Patients who undergo Roux-en-Y gastric bypass (RYGB) have significant weight loss, and abdominoplasty is an effective corrective surgery for removing excess skin. This study aimed to evaluate the impact of the weight of removed tissue on the development of postoperative complications in patients undergoing abdominoplasty without lipoaspiration after gastric bypass at the Federal District North Wing Regional Hospital, Brasília, Brazil. Methods Data were analyzed from a prospective registry of patients who underwent abdominoplasty without lipoaspiration after gastric bypass from January 2011 to December 2018. The variables examined included body mass index (BMI) before RYGB and before plastic surgery, weight loss, weight of the excised abdominal flap, comorbidities, and medical complications. Analysis of the role of the weight of the removed tissue after abdominoplasty was performed to assess outcome measures. Results One hundred sixty-three patients were included. The mean age of the patients was 42 years. Their BMI at the time of abdominoplasty was 27.49 kg/m2, and the average weight loss before abdominoplasty was 47.13 kg. The preweight loss BMI was 45.27 kg/m2, and the ΔBMI was 17.78 kg/m2. The overall complication rate was 29.4%. An amount of removed tissue from the abdomen ≥ 2000 g significantly increased the rates of postoperative complications (46.7% vs. 19.4%; p = 0.002; OR = 3.13). Conclusions Removal of ≥ 2000 g of tissue from the abdomen led to significantly more complications in patients who underwent abdominoplasty after gastric bypass. In addition, this group of patients was significantly associated with the presence of higher anthropometric variable values (BMI, weight loss, max BMI, and ΔBMI) and not associated with the presence of comorbidities.
