Background: Despite its worldwide popularity, laparoscopic adjustable gastric banding (LAGB) requires revisional surgery for failures or complications, in 20-60% of cases. The purpose of this study was to compare in terms of efficacy and safety, the conversion of failed LAGB to laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy. (LSG).
Methods: The bariatric database of our institution was reviewed to identify patients who had undergone conversion of failed LAGB to LRYGB or to LSG, from November 2007 to June 2012.
Results: A total of 108 patients were included. Of these, 74 (68.5%) underwent conversion to LRYGB and 34 to LSG. All of the procedures were performed in 2-stage and laparoscopically. The mean follow-up for the LRYGB group was 29.1±17.9 months while for the LSG patients was 24.2±14.3 months. The mean body mass index (BMI) prior LRYGB and LSG was 45.6±7.8 and 47.5±5.6 (P = .09), respectively. Postoperative complications occurred in 16.2% of the LRYGB patients and in 2.9% of the LSG group (P = .04). Mean percentage of excess weight loss was 59.9%±16.2% and 70.2%±16.7% in LRYGB, and it was 52.2%±11.4% and 59.9%±14.4% in LSG at 12 months (P = .007) and 24 months (P = .01) after conversion.
Conclusion: In this series, LRYGB and LSG are both effective and adequate revisional procedure after failure of LAGB. While LRYGB seems to ensure greater weight loss at 24 months follow-up, LSG is associated with a lower postoperative morbidity.

Background: Lower access to fresh foods and lower income level are associated with greater obesity rates.
Objectives: We aim to study if weight loss 1 year after bariatric surgery is associated with living in areas defined as food deserts, that is, low access to foods and lower income.
Setting: Virginia Commonwealth University Hospital System, Richmond, VA; Academic Center.
Background: Severe obesity is associated with a low-grade chronic inflammation, and high-sensitivity C-reactive protein (hs-CRP) is a marker that can be used to evaluate chronic inflammation status. Metabolic bariatric surgery (MBS) is shown to decrease hs-CRP level, but long-term results are scarce, and association with weight loss outcomes is undetermined. This study aims to evaluate chronic inflammation in patients with obesity using hs-CRP, and its association with long-term weight loss outcomes after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).

Background: The impact of preoperative weight loss on long-term weight loss outcomes and comorbidity resolution in both laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are poorly reported. Understanding this relationship is necessary to guide surgeons toward appropriate procedure and patient selection. The present study investigates long-term weight loss outcomes and comorbidity resolution following LSG and LRYGB and investigates the effect of preoperative variables on long-term outcomes.
