Analysis of the Association between Eating Behaviors and Weight Loss after Laparoscopic Sleeve Gastrectomy.

ABSTRACT: SETTING:In a private medical center, 300 patients who underwent a laparoscopic sleeve gastrectomy (LSG) were classified into 4 groups according to their eating behaviors (EB) preoperatively. During a 3-year postoperative follow-up, dietary changes in relation to weight loss were studied. OBJECTIVES:To explore the influence of abnormal EB on the outcome of sleeve gastrectomy. BACKGROUND:Patients with morbid obesity often suffer from abnormal EB. After LSG, the outcome depends largely on improvement of the feeding behaviors acquired. METHODS:This prospective study includes 300 patients who underwent LSG from 2013 to 2014, divided into the following 4 groups: binge eaters, snack eaters, sweet eaters, and volume eaters. RESULTS:The average age was 41.65 years, the ratio of male to females was 1 to 2. The average baseline body mass index (BMI) was 42.02. After 3 years, no significant change was found in the number of binge eaters (p = 0.396), but there was an 8.9% increase in snack eaters (p < 0.001), a 12.9% increase in sweet eaters (p < 0.001), and 17.2% increase in healthy eating habits (p < 0.001). Sixty-five (24.8%) patients did not experience changes in their eating patterns. However, after surgery, 24.6% of the patients continued with the same EB and 125 (49.5%) patients changed from one EB to another unhealthy EB. Weight loss, measure as ?BMI, was similar in each group after 3 years, with a mean BMI of 29.8. When eating habits were related to different features such as gender, sports practice, type of work, smoking, marital status, comorbidities, no influence on the operative results were found. CONCLUSION:LSG promotes the reduction of overeaters; however, it promotes a switch between other unhealthy EB. The significant increase in snack eaters and sweet eaters is outstanding, although it did not affect weight loss in the midterm follow-up. Worsening of eating habits after LSG is a common fact.

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.

Project description:BACKGROUND:Laparoscopic sleeve gastrectomy (LSG) modifies the upper gastrointestinal tract motility. Controversial data currently exist. The aim of the study was to evaluate esophageal motility before and after LSG. PATIENTS AND METHODS:Morbid obese patients scheduled for LSG underwent reflux symptoms evaluation and manometry preoperatively and postoperatively. The preoperative and postoperative results were compared and analyzed. RESULTS:Eighteen patients were enrolled. Heartburn and regurgitation improved in 38.9% and 11.1% of the patients, but deteriorated in 11.1% and 27.8% of the patients, respectively. Lower esophageal sphincter (LES) total length decreased postoperatively (p=0.002). Resting and residual pressures tended to decrease postoperatively (mean difference [95% confidence interval]: -4 [-8.3/0.2] mmHg, p=0.060; -1.4 [-3/0.1] mmHg, p=0.071, respectively). Amplitude pressure decreased from 95.7±37.3 to 69.8±26.3 mmHg at the upper border of LES (p=0.014), and tended to decrease at the distal esophagus from 128.5±30.1 to 112.1±35.4 mmHg (p=0.06) and mid-esophagus from 72.7±34.5 to 49.4±16.7 mmHg (p=0.006). Peristaltic normal swallow percentage increased from 47.2±36.8 to 82.8±28% (p=0.003). Postoperative regurgitation was strongly negatively correlated with LES total length (Spearman's r=-0.670). When groups were compared according to heartburn status, statistical significance was observed between the groups of improvement and deterioration regarding postoperative residual pressure and postoperative relaxation (p<0.002, p<0.002, respectively). With regard to regurgitation status, there was statistically significant difference between groups regarding preoperative amplitude pressure at the upper border of LES (p<0.056). CONCLUSION:Patients developed decreased LES length and weakened LES pressure after LSG. Esophageal body peristalsis was also affected in terms of decreased amplitude pressure, especially at the upper border of LES. Nevertheless, body peristalsis was normalized postoperatively. LSG might not deteriorate heartburn. Regurgitation might increase following LSG due to shortening of LES length, particularly in patients with range of preoperative amplitude pressure at the upper border of LES of 38.9-92.6 mmHg.
