Seven-Year Outcomes of Laproscopic Sleeve Gastectomy in Indian Patients with Different Classes of Obesity.

BACKGROUND

The aim of the study was to assess the long-term outcome in terms of weight loss and remission of comorbidities among the patients who had undergone LSG in an Indian setting.

METHODS

This is a retrospective observational study of patients (BMI > 30 kg/m) who underwent LSG having a minimum 6 months of follow-up data. Based on preoperative BMI, patients were grouped as class 1, 30 < BMI < 35 kg/m; class 2, 35 < BMI < 40 kg/m; and class 3, BMI > 40 kg/m. Data on BMI and %EWL between three classes and among genders at different follow-up points for 7 years were compared.

RESULT

Study included 95 patients (mean age of 33.7 ± 11 years), and the preoperative mean BMI was 40.2 ± 5.1 kg/m. At one year of surgery, 85.5% patients achieved > 50%EWL. The highest mean %EWL was found in class 1 (66.19%), followed by class 2 (56.73%) and class 3 (46.59%) at the sixth month follow-up. At the seventh year, %EWLs were 85.11% (class 1), 76.69% (class 2), and 62.98% (class 3) and the mean BMIs were 25.13 ± 3.09 kg/m (class 1), 26.86 ± 2.12 kg/m (class 2), and 31.07 ± 3.39 kg/m (class 3) and were significantly different (p < 0.05). At the last follow-up, though, the males showed slight weight regain; however, there were no statistical differences between the genders (p = 0.065).

CONCLUSION

Outcome from LSG was better in patients with BMI < 40 kg/m compared to the patients with BMI > 40 kg/m. Remission of obesity-related comorbidities was observed with LSG in all groups and gender did not influence the outcome significantly.
