Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) have shown different weight loss results. These differences might be partly due to dumping after LRYGB, forcing sweet eaters to switch to a healthy diet. The Dutch Sweet Eating Questionnaire (DSEQ) is validated to measure sweet eating. This study aims to investigate if sweet eating measured with the DSEQ influences weight loss. Methods: In this multicenter randomized controlled trial, patients were included between 2013 and 2017 in two Dutch high-volume hospitals, and randomized with a 1:1 ratio between LRYGB and LSG. Primary outcome measure was weight loss. Secondary outcome measure was sweet eating behavior, measured with the DSEQ. Data was collected at baseline, 1 year and 2 years postoperatively. Results: Data was analyzed of 623 patients who underwent LRYGB (n = 308; 49.4%) or LSG (n = 315; 50.6%). Follow-up rates at 2 years postoperative were 67.1% for weight and 35.3% for DSEQ. At 2 years postoperative, mean BMI was significantly higher after LSG than LRYGB (respectively 30.88 versus 28.87 kg/m2, p < 0.001), and the percentage of sweet eaters was significantly higher after LSG than LRYGB (respectively 8.6% versus 2.6%, p = 0.049). None of the preoperative sweet eaters were sweet eaters 2 years after LRYGB (0.0%), versus 11.8% 2 years after LSG. No correlation was found between postoperative sweet eating behavior and %EBMIL. Conclusion: No significant correlation was found between preoperative or postoperative sweet eating measured with the DSEQ and weight loss. The decision-making for the procedure type is more complex than weight loss and dietary habits, and should also involve quality of life and presence of comorbidities. These factors should be addressed in future research along with longer term results. Trial Registration: Dutch Trial Register NTR-4741 [ABSTRACT FROM AUTHOR]

Obesity is a major risk factor for cardiovascular disease. Data on structural and functional arterial changes after bariatric surgery are scarce. The aim of this study was to determine the effects of bariatric surgery on the carotid intima media thickness (cIMT) and pulse wave velocity (PWV). General hospital. We collected data prospectively in 200 patients scheduled for bariatric surgery between 2015–2017. Based on an increase or decrease of 1 standard deviation of the mean difference in cIMT and PWV 1 year postoperatively, patients were divided into progressors, regressors', and unchanged. We analyzed data on medical history, baseline body mass index, surgery type, and difference in body mass index after 1 year. Data on cIMT were available for 134 patients. Thirty-four patients (25.4%) had a cIMT regression with a mean decrease of.1 mm (−.24 to −.06), 10 patients (7.5%) were progressors with a mean increase of.1 mm (.07–.30), and 90 patients (67.2%) remained unchanged. Progressors more often had type 2 diabetes (P =.035) and hypertension (P =.020). Data on PWV were available for 120 patients, of whom 91 (75.8%) were regressors, 26 (21.6%) remained unchanged, and 3 (2.5%) were progressors. Predictors of PWV changes were total plasma cholesterol and hypertension at baseline. A significant improvement of the vascular quality already after 1 year of follow-up was established in 25%–76% of all patients after bariatric surgery and the vast majority showed stabilization. • Obesity is a major risk factor for cardiovascular disease (CVD) • Vascular quality can be assessed with intima media thickness or pulse wave velocity • Bariatric surgery can improve the vascular quality in 25-76% of all patients [ABSTRACT FROM AUTHOR]

Background: Morbidly obese patients are at higher risk of complications after surgery. In bariatric surgery, pre- and intra-operative checklists are commonly used to identify high-risk patients preoperatively, to decrease the number of postoperative complications. This pilot study evaluates the effect of a postoperative checklist in bariatric surgery, addressing regularly measured parameters, on the occurrence and early recognition of complications. Methods: An in-house developed postoperative checklist was used on the first postoperative day after bariatric surgery and included information on nausea, pain, temperature, heart rate, and laboratory markers. Complications were scored using the Clavien-Dindo (CD) classification, and three groups were formed: no complications (CD0), minor complications (CD1 and 2), and major complications (≥CD3a). Differences between groups were analyzed using nonparametric tests. Results: Six hundred ninety-four subjects were included (79.5% female, age 42.6 ± 10.8 years, BMI 43.8 ± 5.8 kg/m). Twenty-nine subjects developed major complications within 30 days postoperatively. There were no significant differences in baseline characteristics between groups. Subjects with major complications were less willing to be discharged due to complaints, compared to subjects with no or minor complications (14.8 vs. 3.6 and 4.6%, respectively) and had a higher decrease of hemoglobin level (0.8 vs. 0.6 and 0.65 mmol/l, respectively). Conclusion: The patient's willingness for discharge, in combination with hemoglobin decrease, may be the best early predictors of major complications after bariatric surgery. This postoperative checklist may be an adequate instrument to identify patients who can be safely discharged home on the first postoperative day and thereby play a part in patient management after bariatric surgery.
