abstract
Background and Objectives: With obesity rates rising in the United States, bariatric surgery has become a well-established and effective treatment for morbid obesity and its comorbid conditions. Laparoscopic Roux-en-Y gastric bypass and laparoscopic Sleeve Gastrectomy are two of the more common bariatric procedures. This study analyzes whether gender differences play a role in procedure selection and outcomes following either procedure. Methods: Using the American College of Surgeons National Surgical Quality Improvement Program database for years 2015 to 2017, we assessed demographics, postoperative complications, and readmission rates. Chi-square analysis, student t-test, and propensity analyses were performed appropriately. Results: Data review found that men presenting for bariatric surgery had a higher incidence of comorbidities and higher body mass index than women. More men than women underwent Sleeve Gastrectomy (68.5% vs 63.0%, P <0.0001), while more women than men underwent Laparoscopic Roux-en-Y gastric bypass (37.0% vs 31.5%, P < 0.0001). In the Laparoscopic Roux-en-Y group, men experienced more postoperative complications, including cardiac arrest (0.2% vs 0.1%, P = 0.02) and unplanned intubation (0.4% vs 0.2%, P = 0.02). In the Sleeve Gastrectomy group, men experienced more postoperative complications, including myocardial infarction (0.2% vs 0.1%, P = 0.006). In both groups, women experienced higher rates of unplanned readmissions (3.5% vs 2.8%, P = 0.0012). Conclusions: This study found that men are more likely to undergo Sleeve Gastrectomy than Laparoscopic Roux-en-Y gastric bypass, despite higher complication rates for both. Women have higher rates of unplanned readmission rates regardless of procedure, despite lower postoperative morbidity.
