“…Previous meta-analyses have reported that both SG and GB, as the most popular bariatric procedures, have substantial effects on weight loss [14,15]. However, several studies with longer follow-ups, including a metaanalysis of five RCTs with a five-year follow-up, reported that GB resulted in greater EWL% than SG [16][17][18]. According to the present study, both SG and GB resulted in a significant EWL%.…”

Background: Bariatric surgery is an effective treatment for obesity and its associated comorbidities. This is the first comprehensive report of a prospective cohort study, comparing sleeve gastrectomy (SG) with gastric bypass (GB) regarding their effectiveness and safety. Methods: The prospectively collected data of patients, who presented to a specialized bariatric center and underwent a primary bariatric procedure, were compared in terms of weight loss, remission of obesity-associated comorbidities, complication rate, and quality of life improvement at 6-, 12-, and 24-month follow-ups. Results: Of 3287 patients (78.6% female) analyzed, 67% (n = 2202) and 33% (n = 1085) underwent SG and GB, respectively. Effective outcomes were reported in both groups regarding the body composition indices. Type 2 diabetes mellitus (T2DM) remission rate at the end of follow-up was 53.3% and 63.8% in the SG and GB groups, respectively. Following the propensity score-adjusted analysis, the T2DM remission rate was not significantly different between the groups. Conversely, the remission rate of hypertension in the 24-month follow-up (39.1% vs. 54.7%) and the remission rate of dyslipidemia in all follow-ups were lower in the SG group, compared to the GB group. Moreover, both procedures caused substantial improvements in various domains of quality of life. The surgery duration, early complication rate, and nutritional deficiencies were lower in the SG group, compared to the GB group. Conclusion: Both surgical procedures were effective in the control of obesity and remission of its comorbidities. However, since SG was associated with a lower rate of complications, it seems that SG should be considered as a suitable procedure for obese patients, especially those with a healthier metabolic profile.

“…included 11 RCTs in their metaanalysis, and the results showed no difference in %EWL and T2DM between the two surgical methods (LSG and LRYGB), which may be attributed to the lack of longterm follow-up data, with only 3 studies providing data of 3 years and 5 years respectively. Sharples [51] included 5 RCTs and concluded demonstrated a significantly greater %EWL in patients undergoing LRYGB compared with LSG. However, there was no significant difference between LRYGB and LSG in rates of resolution or improvement of diabetes.…”

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are two representative bariatric surgeries. This study aimed to compare the effects of the LSG and LRYGB based on highquality analysis and massive amount of data.Methods: For this study databases of PubMed, Web of Science, EBSCO, Medline, and Cochrane Library were searched for articles published until January 2019 comparing the outcomes of LSG and LRYGB.Results: This study included 28 articles. Overall, 9038 patients (4597, LSG group; 4441, LRYGB group) were included. The remission rate of type 2 diabetes mellitus (T2DM) in the LRYGB group was superior to that in the LSG group at the 3-years follow-up. Five-year follow-up results showed that LRYGB had an advantage over LSG for the percentage of excess weight loss and remission of T2DM, hypertension, dyslipidemia, and abnormally low-density lipoprotein.Conclusions: In terms of the long-term effects of bariatric surgery, the effect of LRYGB was better than of LSG.

“…However, the decision to undergo either LSG or LRYGB should be individualized because other factors need to be taken into account like excess weight loss and long-term success. Although there is limited long-term data available regarding outcomes after bariatric surgery in adolescents, studies in adult populations have suggested that RYGB may result in greater %EWL, improved dyslipidemia outcomes, and a lower incidence of postoperative gastro-esophageal reflux disease [28]. All this data should be discussed with families in the context of a multidisciplinary approach before a surgical procedure is chosen.…”

Thirty-Day Outcomes of Bariatric Surgery in Adolescents: a First Look at the MBSAQIP Database

et al. 2020

Introduction Bariatric surgery is the only effective treatment of severe obesity. The number of adolescents undergoing bariatric surgery is increasing. However, bariatric surgery in adolescents is controversial. Objective The purpose of this study is to evaluate the outcomes of bariatric surgery in adolescents based on the MBSAQIP database (Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project). Methods We analyzed the 2015-2017 MBSAQIP database; patients ≤ 19 years of age were included in our analysis. Primary outcomes were 30-day serious adverse events (SAEs), organ space infection (OSI), re-intervention, and re-operation rates. Secondary outcomes included operation length, hospital stay, and re-admission rates. We conducted separate Mann-Whitney rank sums tests, chi-square, or Fisher's exact tests as appropriate, with p < .05 denoting statistical significance. Results A total of 1983 adolescent patients were included in our analysis. The average age and BMI were 18.1 and 47.5, respectively. Of adolescent patients, 21.7% underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) and 78.3% underwent laparoscopic sleeve gastrectomy (LSG). The 30-day SAE and readmission rates were significantly lower for LSG compared with LRYGB (2.9% and 2.6% vs 6.5% and 5.6%, respectively; p < 0.05). The 30-day reoperation rate was also lower for LSG compared with LRYGB albeit not significant (1.1% and vs 2.3%; p = 0.05). The 30-day intervention rate for LSG was significantly lower, however, compared with LRYGB (1.2% vs 3%; p < 0.05). Compared with adult patients, > 19 years old (n = 353,726), we found no difference in our outcomes. However, adolescents had significantly shorter operation length. Conclusion In adolescents, LSG had fewer SAE, re-intervention, and readmission rates compared with LRYGB. There was no difference in outcomes between adolescents and adults.
