Background: Bariatric surgery is an effective treatment for weight loss, but a higher body mass index (BMI) may lead to higher postoperative complication rates. This study aims to compare perioperative and postoperative outcomes between UAE patients with severe obesity (SO) [BMI ≥ 50 kg/m2] and non-severe obesity (NSO) [BMI < 50 kg/m2] undergoing primary bariatric surgery. Methods: From September 2015 to July 2019, 542 patients, 94 SO (56.5 ± 6.2 kg/m2) and 448 NSO (41.8 ± 4.1 kg/m2), were retrospectively reviewed. Results: Patients with SO were younger (33.8 ± 13.4 vs. 37.0 ± 11.5 years, p = 0.02) but otherwise had similar demographic characteristics. Their rates of Roux-en-Y gastric bypass (39.4% SO vs. 44.4% NSO, p = 0.37) and sleeve gastrectomy (60.6% vs. 55.6%, p = 0.37) were similar. There were no differences between perioperative complications (6.4% SO vs. 5.8% NSO, p = 0.83), major postoperative complications (5.3% vs. 3.5%, p = 0.42), readmissions (5.3% vs. 3.3%, p = 0.36), or reoperations (3.2% vs. 2.7%, p = 0.78). There were no mortalities. Their total body weight loss was comparable at 12 months (28.1 ± 10.2% vs. 29.0 ± 7.7%, p = 0.58). Conclusions: Although a higher BMI may pose operative challenges, UAE patients with SO do not have worsened outcomes in bariatric surgery, demonstrating similarly low morbidity to patients with NSO, and similar rates of improvement in their BMI.

Background: findings from the previously conducted studies indicate altered regulatory mechanisms of calcium and vitamin D metabolism in obese patients and a role for bariatric surgery in regulating vitamin D metabolism; however, the available data is controversial and does not provide an adequate understanding of the subject. Methods: we evaluated serum parameters of vitamin D and mineral metabolism (vitamin D metabolites (25(OH)D3, 25(OH)D2, 1,25(OH)2D3, 3-epi-25(OH)D3, and 24,25(OH)2D3), vitamin D-binding protein (DBP), free 25(OH)D, fibroblast growth factor 23 (FGF-23), parathyroid hormone (PTH), total calcium, albumin, phosphorus, creatinine, magnesium) in 30 patients referred for bariatric surgery in comparison with 30 healthy volunteers of similar age, sex and baseline 25(OH)D3. Patients were also followed up with repeated laboratory assessments 3 months and 6 months after surgery. During the first 3 months, patients were prescribed high-dose cholecalciferol therapy (50,000 IU per week), with subsequent correction based on the results of the 3-month visit examination. Results: Preoperatively, patients with morbid obesity were characterized by a high prevalence of vitamin D deficiency (median 25(OH)D3 level 11.9 (6.8; 22.2) ng/mL), significantly lower levels of active vitamin D metabolite 1,25(OH)2D3 (20 (10; 37) vs. 39 (33; 50) pg/mL, p < 0.001), lower serum albumin-adjusted calcium levels (2.24 (2.20; 2.32) vs. 2.31 (2.25; 2.35) mmol/L, p = 0.009) and magnesium levels (0.79 (0.72; 0.82) vs. 0.82 (0.78; 0.85) mmol/L, p = 0.043) with simultaneous similar PTH levels (p = 0.912), and higher DBP levels (328 (288; 401) vs. 248 (217; 284) mg/L, p < 0.001). The 25(OH)D3 levels remained suboptimal (24.5 (14.7; 29.5) ng/mL at the 3-month visit and 17.9 (12.4; 21.0) ng/mL at the 6-month visit, p = 0.052) despite recommended high-dose cholecalciferol supplementation. Patients also demonstrated an increase in 1,25(OH)2D3 levels (38 (31; 52) pg/mL at the 3-month visit and 49 (29; 59) pg/mL at the 6-month visit, p < 0.001) without a change in PTH or calcium levels during the follow-up. Conclusion: our results of a comprehensive laboratory evaluation of vitamin D status and mineral metabolism in patients undergoing bariatric surgery highlight the importance of improving current clinical guidelines, as well as careful monitoring and education of patients.

Background: The current design of biliopancreatic diversion with duodenal switch (BPD/DS) and single anastomosis duodenal–ileal bypass with sleeve (SADI-S) emphasizes the importance of the pylorus’ preservation to reduce the incidence of marginal ulcer (MU) and dumping. However, no institutional studies have yet reported data on their prevalence. We aimed to assess the incidence of MU and dumping after duodenal switch (DS) and identify the associative factors. Methods: A multi-center review of patients who underwent BPD/DS or SADI-S between 2008 and 2022. Baseline demographics, symptoms, and management of both complications were collected. Fisher’s exact test was used for categorical variables and the independent t-test for continuous variables. Results: A total of 919 patients were included (74.6% female; age 42.5 years; BMI 54.6 kg/m2) with mean follow-up of 31.5 months. Eight patients (0.9%) developed MU and seven (0.8%) had dumping. Patients who developed MU were more likely to be using non-steroidal anti-inflammatory drugs (NSAID) (p = 0.006) and have a longer operation time (p = 0.047). Primary versus revisional surgery, and BDP/DS versus SADI-S were not associated with MU or dumping. Conclusions: The incidences of MU and dumping after DS were low. NSAID use and a longer operation time were associated with an increased risk of MU, whereas dumping was attributed to poor dietary habits. Full article

Abstract
Patients undergoing metabolic surgery have factors ranging from anatomo-surgical, endocrine metabolic, eating patterns and physical activity, mental health and psychological factors. Some of the latter can explain the possible pathophysiological neuroendocrine, metabolic, and adaptive mechanisms that cause the high prevalence of weight regain [...] Read more.
Patients undergoing metabolic surgery have factors ranging from anatomo-surgical, endocrine metabolic, eating patterns and physical activity, mental health and psychological factors. Some of the latter can explain the possible pathophysiological neuroendocrine, metabolic, and adaptive mechanisms that cause the high prevalence of weight regain in postbariatric patients. Even metabolic surgery has proven to be effective in reducing excess weight in patients with obesity; some of them regain weight after this intervention. In this vein, several studies have been conducted to search factors and mechanisms involved in weight regain, to stablish strategies to manage this complication by combining metabolic surgery with either lifestyle changes, behavioral therapies, pharmacotherapy, endoscopic interventions, or finally, surgical revision. The aim of this revision is to describe certain aspects and mechanisms behind weight regain after metabolic surgery, along with preventive and therapeutic strategies for this complication.
