Roux-en-Y Gastric Bypass vs Vertical Sleeve Gastrectomy in the Remission of Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis

<b><br>Introduction:</b> Obesity's associated comorbidities and treatment costs have risen significantly, highlighting the importance of early weight loss strategies. Bariatric surgeries like Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) have been effective in promoting weight loss and improving type 2 diabetes mellitus (T2DM) management.</br> <b><br>Aim:</b> The aim was to determine whether Roux-en-Y gastric bypass is more effective than vertical sleeve gastrectomy in the remission of type 2 diabetes mellitus (T2DM).</br> <b><br>Methods:</b> A systematic review and meta-analysis was performed. A literature search was performed in the databases Web of Science, Medline/PubMed, Embase, Scopus, and Medline/Ovid. A total of 1323 results were identified; after screening, 14 articles were selected and included in the systematic review. Primary and secondary outcomes were measured by RR with a 95% CI.</br> <b><br>Results:</b> The primary outcome of T2DM remission was 15% in favor of VSG (RR: 1.15, [95% CI: 1.04-1.28]). For secondary outcomes, hypertension remission was 7% in favor of VSG (RR: 1.07, [95% CI: 1.00-1.16]). Remission of dyslipidemia was 16% in favor of VSG (RR: 1.16, [95% CI: 1.06-1.26]). BMI after surgery was in favor of RYGB (MD: -1.31, [95% CI: -1.98 to -0.64]). For weight loss, the results favored VSG (MD: 6.50, [95% CI: 4.99-8.01]). In relation to total cholesterol, they were 65% favorable for RYGB (MD: -0.35, [95% CI: -0.46 to -0.24]), with a value of p <0.05. For LDL values, our results were 69% favorable for RYGB (MD: -0.31, [95% CI: -0.45 to -0.16]), p <0.01 value.</br> <b><br>Conclusions:</b> Laparoscopic sleeve gastrectomy is more effective in T2DM remission, hypertension remission, dyslipidemia remission, and weight loss compared to Roux-en-Y gastric bypass. Roux-en-Y gastric bypass is more effective at lowering BMI, total cholesterol, LDL, and TG compared to laparoscopic sleeve gastrectomy.</br>.

Does ERAS impact outcomes of laparoscopic sleeve gastrectomy in adolescents?

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols have been successfully implemented in several surgical fields; however, the application of ERAS in the pediatric population is still limited.

OBJECTIVES

The aim was to determine if implementation of an ERAS protocol can improve outcomes of laparoscopic sleeve gastrectomy (LSG) in adolescents.

SETTING

University Hospital, United States.

METHODS

A retrospective analysis of 112 adolescent patients who underwent LSG from February 2011 to July 2019 was conducted. An ERAS protocol was instituted in June 2016. Conventional care patients (n = 51) were compared with ERAS patients (n = 61). Comparisons were made using Χ² tests or Fisher's exact for categoric data and Wilcoxon-rank sum tests for continuous data. Multiple linear regression was used to adjust length of stay for patient characteristics.

RESULTS

The 2 cohorts were similar in age, sex, race, number of co-morbidities, and preoperative body mass index. The volume of intraoperative fluid, intraoperative and postoperative opioids were significantly reduced in the ERAS group (P < .0001). The number of ERAS elements received per patient increased from a median of 9 to 15 (P < .0001). ERAS group had more discharges on postoperative day 1 (48% versus 6 %, respectively). Length of stay was significantly lower in the ERAS group (2.34 versus 2.04 median d, respectively). Difference was still significant after adjusting for age, sex, race/ethnicity, payor status, American Society of Anesthesiologists score, preoperative body mass index, and the duration of surgery (P < .0001). There were no differences in postoperative complications and 30-day readmissions.

CONCLUSIONS

An LSG ERAS protocol is associated with significant reduction in perioperative opioid use and length of stay with no increase in complications or readmission rates.
