Comparison of laparoscopic sleeve gastrectomy to laparoscopic Roux-en-Y gastric bypass for morbid obesity in a military institution

Micronutrient and Protein Deficiencies After Gastric Bypass and Sleeve Gastrectomy: a 1-year Follow-up

“…After 1 year, we observed that GBP led to significantly greater weight loss compared to SG, in accordance with previous data from the literature, including a large multicenter study [33,34]. Nevertheless, some controversy remains.…”

Roux-En-Y Gastric Bypass Vs. Sleeve Gastrectomy: Balancing the Risks of Surgery with the Benefits of Weight Loss

“…There is a similar trend across all weight loss surgery centers in the USA [33]. However, our results, and those of other similar studies [4–13, 15–19, 21–24, 27], suggest a greater weight loss and/or improvement in obesity-related comorbidities including diabetes and hyperlipidemia, as well as similar rates of serious (grades II–III) complications with GB [14]. The established drawbacks of GB are the increase in grade I complications, extended length of stay, and emergency department visits.…”

“…Large observational studies and RCTs ( n  > 50) as well as a meta-analysis show either no differences between procedures [9] or a greater rate of one or more of the following for GB: minor complications, longer hospital stay, and longer operative time [8, 10, 12, 14, 16, 18–24]. …”

Laparoscopic sleeve gastrectomy: long-term weight loss outcomes

“…Guzman et al report 73.7 % EWL at 3 years [12], which is consistent with 3-year results reported by Zachariah et al at 73.0% EWL, who also report 63.7% EWL at 5 years [13]. Lim et al report similar finding at 5 years, with 57.1% EWL [14]. All these numbers are consistent with the results of the meta-analysis by Demantis et al The consistency of these results at increasing followup and our 7-year results suggest weight loss is enduring with LSG.…”
