Introduction
The American Society of Metabolic and Bariatric Surgery (ASMBS) and the International Federation of Surgery for Obesity (IFSO) have both stated that bariatric surgery (BS) should not be denied in Class I patients. However, lifestyle intervention (LI), such as diet plus gym programs, is still considered the preferred approach for subjects with a BMI ranging from 30 to 35 kg/m2. The aim of this study was to retrospectively compare results of LI and BS in patients in Class I obesity.
Methods
Retrospective analysis of prospective maintained databases of two centers for the “Interdisciplinary Treatment of Obesity” was performed. All patients in Class I obesity and follow-up >7 years were included in the study. Subjects were divided into two groups: BS group that included patients who had undergone surgery and LI group that included patients who underwent lifestyle intervention (LI). Percentage of excess body mass index loss (%EBMIL) and comorbidities remission were recorded.
Results
Seventy-six patients were included in the study. Fifty-six subjects were submitted to surgery (BS group); 20 subjects were treated with nonsurgical approach (LI group). In BS group, 34 underwent laparoscopic adjustable gastric band, 13 laparoscopic sleeve gastrectomy (LSG), and 9 laparoscopic Roux-en-Y gastric bypass. EWL% resulted significantly higher in BS group at 1, 3, 5, 7 and 10 years (p < 0.01).
Conclusion
Bariatric surgery is more effective than LI for patients in Class I obesity. Due to its versatility, low-risk profile and high-effectiveness LSG could be the standard intervention for these patients.
