Background: Clinical trials in the field of bariatrics, and specifically laparoscopic adjustable gastric banding (LAGB), have frequently been gender imbalanced, with males representing only 20% of examinees. Long-term gender-oriented results, and specifically quality of life (QOL) parameters, have not been addressed sufficiently. The aim of our study was to examine the long-term gender association with outcome of LAGB including the impact on QOL. Methods: A retrospective cohort study of patients who underwent LAGB between 2006 and 2014 by a single surgeon was conducted. Data were collected from the hospital registry and a telephone interview that included a standardized questionnaire. Outcomes including BMI reduction, evolution of comorbidities, complications, reoperations, and QOL were compared according to the Bariatric Analysis and Reporting Outcome System (BAROS). Results: Included were 114 males and 127 females, with a mean age of 38.2 years at surgery, and an average post-surgery follow-up of 6.5 years. Similar BMI reduction (p = 0.68) and perioperative complication rates (p = 0.99) were observed. Males had a greater improvement in comorbidities (p < 0.001), less band slippage (p = 0.006), underwent fewer reoperations (p = 0.02), and reported higher QOL scores (p = 0.02) than females. The total BAROS score was significantly higher for males than females (p < 0.001). Conclusions: LAGB surgery results in better outcomes for male than female patients as measured by the BAROS, despite a similar BMI reduction. Gender-specific outcomes should be taken into consideration in optimizing patient selection and preoperative patient counseling.
