Mid-term bariatric surgery outcomes for obese patients: does weight matter?

Area of Science:

• Bariatric surgery outcomes
• Obesity management
• Metabolic and bariatric surgery

Background:

• Identifying prognostic indicators for bariatric surgery success is crucial.
• This study investigates the impact of obesity degree on surgical outcomes.
• Patients with varying obesity levels (morbid, super, super-super) were analyzed.

Purpose of the Study:

• To determine if obesity severity influences outcomes after bariatric surgery.
• To compare restrictive versus malabsorptive procedures in different obesity classes.
• To evaluate weight loss and comorbidity resolution based on BMI and surgical type.

Main Methods:

• Retrospective analysis of prospectively maintained database.
• Included laparoscopic adjustable gastric bands (LAGB), sleeve gastrectomies (LSG), and Roux-en-Y gastric bypass (LRYGB).
• Patients with at least two years of follow-up were assessed for weight, BMI, excess weight loss, and comorbidity status.

Main Results:

• A total of 353 patients were analyzed; 61.8% underwent LRYGB.
• LRYGB showed significantly higher excess weight loss and BMI reduction in morbidly and super-obese groups (P < 0.001).
• Complete diabetes remission was higher with LRYGB in morbidly and super-obese groups (P < 0.05); sleep apnea, asthma improved.

Conclusions:

• Laparoscopic Roux-en-Y gastric bypass (LRYGB) yields the best mid-term results for weight loss and comorbidity resolution in super-obese patients.
• LRYGB demonstrated comparable complication rates to LAGB and LSG in this cohort.
• The degree of obesity impacts bariatric surgery outcomes, with LRYGB being particularly effective for severe obesity.
