Background: Bariatric surgery is considered the most effective treatment for severe obesity. Despite this wide success, bariatric surgery is associated with increased risks of nutritional deficiencies.

Objectives: To examine whether Roux-en-Y-gastric bypass (RYGB) alters essential fatty acid (FA) status and inflammation markers.

Methods: Subjects with obesity (n = 28; BMI > 40 kg/m2; mean age 48 years) were studied before and 1 year after RYGB. We collected blood samples before and 12 months after RYGB, and analyzed FA in RBCs and peripheral blood mononuclear cells (PBMC), and measured inflammation parameters in plasma. The proportion of total n-3 FAs was the primary outcome, while parameters related to other FAs and inflammation factors were the secondary parameters. In addition, PBMCs from 15 of the participants were cultured alone or with 100 and 200 μM DHA, and the production of IL-6, IL-1β, PGE2, and prostaglandin F2-alpha (PGF2α) was assayed after endotoxin (LPS) stimulation.

Results: RYGB induced a significant reduction of BMI (-30%) and improvement of insulin resistance (-49%). While the proportion of arachidonic acid was 15% higher after RYGB, the proportions of total and individual n-3 FAs were 50%-75% lower (P < 0.01). Consequently, the RBC omega-3 index and n-3:n-6 fatty acid ratio were 45% and 50% lower after surgery, respectively. In isolated PBMCs, LPS induced the production of IL-6, IL-1β, PGE2, and PGF2α in both pre- and post-RYGB cells, but the effects were 34%-65% higher (P < 0.05) after RYGB. This effect was abrogated by DHA supplementation.

Conclusions: This study presents evidence that RBC and PBMC n-3 FAs are severely reduced in patients with obesity after RYGB. DHA supplementation in PBMC moderates the production of inflammation markers, suggesting that n-3 FA supplementation would merit a trial in bariatric patients.

Large series examining laparoscopic adjustable gastric banding as a salvage solution for failed gastric bypass.

Background: The Roux-en-Y gastric bypass (RYGB) has long been considered the gold standard of weight loss procedures. However, there is limited evidence on revisional options with both minimal risk and long-term weight loss results.

Objective: To examine percent excess weight loss, change in body mass index (BMI), and complications in patients who underwent laparoscopic adjustable gastric banding (LAGB) over prior RYGB.

Setting: Academic hospital.

Methods: Retrospective analysis of a single-center prospectively maintained database. Three thousand ninety-four LAGB placements were reviewed; 139 were placed in patients with prior RYGB.

Results: At the time of LAGB, the median BMI was 41.3. After LAGB, we observed weight loss or stabilization in 135 patients (97%). The median maximal weight loss after LAGB was 37.7% excess weight loss and -7.1 change in BMI (P < .0001). At last follow-up visit, the median weight loss was 27.5% excess weight loss and -5.3 change in BMI (P < .0001). Median follow-up was 2.48 years (.01-11.48): 68 of 132 eligible (52%) with 3-year follow-up, 12 of 26 eligible (44%) with 6-year eligible follow-up, and 3 of 3 eligible (100%) with >10-year follow-up. Eleven bands required removal, 4 for erosion, 4 for dysphagia, and 3 for nonband-related issues.

Conclusions: LAGB over prior RYGB is a safe operation, which reduces the surgical risks and nutritional deficiencies often seen in other accepted revisional operations. Complication rates were consistent with primary LAGB. Weight loss is both reliable and lasting, and it can be considered as the initial salvage procedure in patients with failed gastric bypass surgery.
