Amino Acid Metabolites and Slow Weight Loss in the Early Postoperative Period after Sleeve Gastrectomy.

ABSTRACT: BACKGROUND:Profiles of amino acid metabolites (AAMs) have been linked to obesity and energy homeostasis. We investigated whether baseline obesity-related AAMs were associated with weight status in the early postoperative period after sleeve gastrectomy. METHODS:In this prospective, single-arm, longitudinal study, 27 bariatric patients underwent sleeve gastrectomy. Twenty obesity-related AAMs were comprehensively quantified prior to surgery, and slow weight loss was defined as the lowest 40% of the percentage excess weight loss (%EWL) at three and six months postoperatively. Linear regression models were used to assess the association between baseline obesity-related AAMs and %EWL, and receiver operating characteristic curves were assessed. RESULTS:Isoleucine and metabolites from the serotonin pathway were significantly associated with the %EWL at three and six months after sleeve gastrectomy. Among the metabolites identified to be significant in the regression analyses, serotonin (area under receiver operating characteristic curves (AUROC): 0.79, 95% confidence interval (CI): 0.59-0.97) and serotonin/5-hydroxytryptophan ratio (AUROC: 0.80, 95% CI: 0.58-1.00) showed superior performance in predicting slow weight loss six months after sleeve gastrectomy. CONCLUSIONS:Our findings underscore the importance of baseline AAM profiles, especially serotonin and serotonin/5-hydroxytryptophan ratio, in predicting slow weight loss in the early postoperative period after sleeve gastrectomy.

Project description:Objective: To evaluate (1) the efficacy of transit bipartition (TB) as revisional bariatric surgery (RBS) after laparoscopic sleeve gastrectomy (LSG); (2) the impact of the length of the common channel (CC) on weight loss. Background: LSG in combination with TB has been shown to be highly efficacious for treating morbid obesity. The role of TB as RBS to address the problem of primary failure or weight recidivism after LSG is less well defined. Methods: Observational study of outcomes in 100 morbidly obese patients who received a TB following LSG. Follow-up examinations (FE) were performed at 1, 3, 6, and 12 months. Variables analyzed included BMI, percent excess weight loss (%EWL), total body weight loss (%TBWL), effect on obesity-related conditions and complications. Results: The mean BMI before LSG was 49.9 ± 8.5 kg/m2. A nadir of 32.7 ± 6.1 kg/m2 was reached 22.1 ± 16.9 months after LSG (%EWL 70.0 ± 14.5). The time interval between LSG and TB was 52.2 ± 26.6 months at which the BMI had increased to 37.6 ± 7.1 kg/m2 and %EWL decreased to 49.4 ± 19.7. Following TB, the BMI decreased continuously to 31.4 ± 5.7 kg/m2 after 12 months with a parallel increase in %EWL to 74.7 ± 20.3 and %TWL reaching 36.3 ± 10.5. Weight loss was significantly higher for CC length of 250 versus 300 cm after 12 months (BMI 29.4 ± 5.3/33 ± 5.3 kg/m2, P = 0.002; %EWL 79.8 ± 26.6/70.4 ± 17; P = 0.009). Improvement of comorbidities was observed in a high proportion of patients. Major early complications occurred in 3% of the patients. Conclusion: TB is an effective second-step procedure to address insufficient weight loss or weight recidivism after LSG. CC length of 250 versus 300 cm had a significant impact. While most improvements of obesity-related comorbidities are likely linked to weight loss, amelioration of GERD is largely mediated by accelerated gastric emptying. Major complications were observed in 3% of patients and managed without fatalities. Mini-Abstract: Weight regain after laparoscopic sleeve gastrectomy (LSG) is a common problem in the treatment of morbid obesity. We evaluated the efficacy of transit bipartition (TB), also termed SASI bypass, to address primary failure or weight regain following LSG in 100 patients. TB proved to be an effective second-step procedure with excess weight loss reaching 75% after 12 months and significant improvement of obesity-related comorbidities.
