AbstractAimPublished reports showed conflicting results regarding the sustained alterations in leptin, chemerin, and ghrelin concenratios after metabolic surgery. Therefore, we performed the present work to contrast the alterations in leptin, chemerin, and ghrelin levels one year after Roux-en-Y gastric bypass (RYGB) versus laparoscopic sleeve gastrectomy (LSG).MethodsThe present research is a prospective, comparative one that followed 100 cases for whom RYGB or LSG was done. We assessed the serum values of adiposity-associated mediators, including adipokcytokines (leptin and active chemerin) and gastrointestinal hormones ...

(Society for Endocrinology) While weight-loss surgeries are not usually performed in people above the age of 65, a new study shows that these procedures can lead to successful weight loss and better diabetes control in older adults. The study, presented at the Society for Endocrinology annual conference in Brighton, UK, indicates that elderly patients treated with bariatric surgery (gastric bypass or gastric sleeve) can recover well and have a reduced risk of obesity-related complications, including heart disease and diabetes.

ConclusionsDJB in obese mice fed a high calorie diet promotes dramatic fecal loss, which could account for the dramatic weight loss and metabolic benefits observed. This could dominate the effects of the mouse genotype/phenotype. Thus, fecal energy loss should be considered as an essential process contributing to the metabolic benefits of DJB in obese mice.

AbstractPost-bariatric hypoglycemia (PBH) can be a serious complication after Roux-en-Y gastric bypass (RYGB), and treatment with somatostatin analogs has been suggested. We investigated the acute effects of three different doses of pasireotide (75 μg, 150 μg, and 300 μg) on the postprandial glucose metabolism in five RYGB-operated individuals with PBH using a mixed meal test. All three doses prevented hypoglycemia but were associated with a notable increase in postprandial hyperglycemia. Moreover, all doses greatly diminished insulin, C-pe ptide, and glucagon-like peptide-1 responses. Considering its strong hyper...

ConclusionWLG group did not have decreased perioperative morbidity, nor improved weight loss and comorbidity resolution 4 years after surgery. While these findings should also be confirmed by multicenter trials, they question the value of mandated WLG prior to bariatric surgery as they seem ineffective and may limit patient access to surgery.

Risk Factors for Moderate to Severe Pain during the First 24 Hours after Laparoscopic Bariatric Surgery While Receiving Intravenous Patient-Controlled Analgesia. Anesthesiol Res Pract. 2019;2019:6593736 Authors: Iamaroon A, Tangwiwat S, Nivatpumin P, Lertwacha T, Rungmongkolsab P, Pangthipampai P Abstract Objective: To investigate the incidence of and risk factors for moderate to severe pain during the first 24 hours after laparoscopic bariatric surgery. Materials and Methods: This retrospective study included morbidly obese patients who underwent laparoscopic sleeve gastrectomy or Ro...

ConclusionAt least in rats, these data demonstrate an earlier essential role for PYY in gut hormone regulation after RYGB. We understand that PYY contributes to GLP-1 and GIP release and there must be the existence of enteroendocrine communication routes between the distal and proximal small intestine.

AbstractBackgroundWhile evidence of improved renal function following gastric bypass exists, pre-operative predictors of this improvement are not completely known.ObjectivesTo assess the glomerular filtration rate (GFR) 1  year after Roux-en-Y gastric bypass (RYGB) and to identify pre-operative predictors associated with the improvement of renal function.MethodsA historical cohort study, which included 109 obese patients before and 12  months after RYGB, was classified into subgroups according to GFR (normofiltration, hypofiltration (GFR   95th percentile)). The 5th and 95th percentiles were 90 and ...
