Bleeding Risk in Post-bariatric Abdominoplasties: A Large Cohort Study

Area of Science:

• Plastic Surgery
• Bariatric Surgery Outcomes
• Patient Safety

Background:

• Post-bariatric abdominoplasty improves contour and quality of life after massive weight loss.
• Perioperative bleeding is a concern, influenced by thromboprophylaxis and comorbidities.
• Investigating bleeding risk factors in this patient population is crucial.

Purpose of the Study:

• To identify risk factors for bleeding in patients undergoing abdominoplasty after bariatric surgery.
• To analyze the influence of hypertension and bariatric surgery type on bleeding complications.

Main Methods:

• Retrospective data collection from a tertiary center.
• Analysis of patient demographics, comorbidities, bariatric surgery type, and thromboprophylaxis.
• Univariable and multivariable regression analyses to identify bleeding predictors.

Main Results:

• Hypertension was a significant predictor of bleeding (RR=2.5).
• Gastric banding (RR=6.8) and sleeve gastrectomy (RR=3.3) showed higher bleeding risks compared to mini-gastric bypass.
• A cohort of 201 patients was analyzed, with a median age of 44 years.

Conclusions:

• Hypertension is an independent risk factor for bleeding in post-bariatric abdominoplasty.
• Bariatric surgery type impacts bleeding risk, with gastric banding and sleeve gastrectomy being higher risk.
• Preoperative optimization and surgical planning are essential for mitigating bleeding complications.
