Background: Reports of long-term (> 5–15-year) outcomes assessing the safety and efficacy of primary revisional laparoscopic sleeve gastrectomy (LSG) are few. Methods: Retrospective long-term comparisons of primary (pLSG) and revisional (rLSG) procedures were matched for gender, age ± 5 years, and body mass index (BMI) ± 5 kg/m2. Weight loss, associated medical condition status, and patient satisfaction were evaluated. Results: Between May 1, 2006, and December 31, 2016, 194 matched patients with severe obesity (mean BMI 44.1 ± 6.7 kg/m2; age 44.2 ± 10.0 years, 67.0% female) underwent pLSG (n = 97) or rLSG (n = 97) and were followed for a mean 12.1 ± 1.5 vs 7.6 ± 2.1 years. Respective mean weight regain from nadir was 15.0 ± 14.4 kg vs 11.9 ± 12.2 kg. Respective percent mean total weight loss and excess weight loss were 20.9 ± 12.7% and 51.8 ± 33.1%, and 18.3 ± 12.8% and 43.4 ± 31.6% at last follow-up, with no significant difference between groups. Resolution of type 2 diabetes (HbA1C < 6.5%, off medications) was 23.1% vs 11.1%; hypertension 36.0% vs 16.0%; and hyperlipidemia 37.1% vs 35.3%. Patients in the pLSG group were significantly more satisfied with LSG (59.8% vs 43.3%, p < 0.05) and more likely to choose the procedure again. Conclusions: There were no significant differences in long-term weight loss or associated medical condition outcomes in matched pLSG and rLSG patients.
