Abstract
Background
Laparoscopic sleeve gastrectomy (LSG) has gained popularity as a stand-alone bariatric procedure, but only a few reports provide data of long-term outcomes on high-risk patients.
Objective
To evaluate long-term efficacy of LSG as a definitive management on high-risk obese patients and to study factors that predict its success.
Setting
University hospital in Spain.
Methods
A retrospective analysis of prospectively collected data from 134 high-risk patients undergoing LSG from January 2007 through December 2016. Long-term weight loss, resolution of comorbidities, morbidity, and mortality were analyzed.
Results
One hundred thirty-four high-risk patients underwent LSG. The mean overall follow-up time was 70.9 ± 4.5 months. The mean age was 47 ± 11.0 years. The mean preoperative body mass index (BMI) was 55.9 ± 6.7 kg/m2 (83.5% were super-obese and 24.6% had BMI ≥ 60). The incidence of postoperative complications was 15%. Mean percentage of total weight loss (%TWL) at 5, 6, 7, and 8 years was 30.7 ± 12.8%, 28.7 ± 14.0%, 29.7 ± 12.3%, and 27.9 ± 11.1%, respectively. Differences were found in age, preoperative BMI, time to reach nadir weight and percentage of excess weight loss (%EWL) at 1 year between patients considered a failure compared to those considered a success. Using multivariate regression analysis, only age (p = 0.009) and time to reach nadir weight after surgery (p = 0.008) correlated with %EWL at 4 years. Resolution of type 2 diabetes (T2DM) was achieved in 62.2% of patients.
Conclusion
This study supports effectiveness and durability of LSG as a definitive bariatric procedure in high-risk patients.
