Abstract
Introduction:
Several factors can influence the response to laparoscopic sleeve gastrectomy (LSG). However, preoperative quality of life (QOL) as a predictor for weight loss postbariatric surgery has been scarcely studied. The purpose of this study was to evaluate the impact of preoperative QOL and other factors to determine success, in terms of percentage of excess weight loss (%EWL) after LSG.
Methods:
A retrospective analysis of patients operated for LSG was performed. The primary variable for analysis was %EWL, which was categorized as <20%, between 21–49%, 50–75%, and >75%. All the variables (demographics, comorbidities, QOL, and nutritional habits) were paired with %EWL and analyzed.
Results:
A total of 134 patients were evaluated. The mean follow-up and %EWL was 24.4 months and 83.3%, respectively. Patients between 18 and 40 years, patients with baseline body mass index (BMI) between 30 and 39.9 kg/m2, patients without high blood pressure, and those with less impaired QOL previous to surgery had significantly (p = 0.013, 0.01, 0.026, and 0.01) better results in terms of %EWL.
Conclusions:
Our analysis shows that younger patients, those with less BMI, and those without HPB have a greater chance of losing weight after LSD. In addition, less impaired preoperative QOL could be a predictor of success in terms of weight loss.
