Sandra Gillon, Yvonne M Jeanes, John Roger Andersen, Villy Våge
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become more popular in recent years. The aim of this study was to determine the vitamin and mineral status in patients up to 5 years after LSG and to explore changes that occurred from pre-operatively to 1, 2 and 5 years after surgery. METHODS: Data reviewed included age, sex, weight and body mass index (BMI), micronutrient supplements consumed and blood levels of 25 hydroxyvitamin D (25 (OH) D), PTH (parathyroid hormone), ferritin, haemoglobin, folate and vitamin B12, prior to and post-LSG...

As discussed in Part 1, obesity is now a global epidemic affecting a significant and rapidly increasing number of adults, adolescents, and children. As the incidence of obesity has increased, so has the use of bariatric surgery to treat it. A growing number of recently published studies have reported that, despite calcium and vitamin D supplementation, the most frequently performed types of bariatric surgery, the Roux-en-Y gastric bypass (RYGB) and the sleeve gastrectomy (SG), cause significant, ongoing bone loss...

Obesity is the most widespread nutritional problem globally. Bariatric surgery is the preeminent long-term obesity treatment. Bariatric procedures manipulate the intestines to produces malabsorption and/or restrict the size of the stomach. The most enduring bariatric procedure is the Roux-en-Y gastric bypass, which utilizes both restriction (small stomach pouch) and malabsorption (duodenum bypass). The in-vogue procedure is the vertical sleeve gastrectomy - resection of the greater curvature of the stomach (predominantly restrictive)...

Increasing prevalence of morbid obesity in Germany is associated with an increasing number of bariatric surgical interventions.Based on the effectiveness of bariatric surgery with regard to a significant reduction of body weight and comorbidity as well as improvement of the quality of life compared with conservative measures, its value and impact has been substantially increased. Long-term metabolic deficits such as nutrient deficiencies can be considered the main risks of various restrictive, combined and malabsorptive procedures of bariatric surgery...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) as a single-stage procedure has shown to be effective in achieving significant weight loss and resolving obesity-related co-morbidities. However, its nutrition consequences have not been extensively explored. This study aims to investigate weight loss and evolution of nutritional deficiencies in a group of patients 3 years post LSG. METHODS: Retrospective data of a group of patients, 3 years following LSG as a stand-alone procedure was collected...

Obesity is now a global epidemic affecting a significant and rapidly increasing number of adults, adolescents, and children. As the incidence of obesity has increased, so has the use of bariatric surgery as a medical solution. A growing number of studies now report that, despite calcium and vitamin D supplementation, the most frequently performed types of bariatric surgery, the Roux-en-Y gastric bypass and the sleeve gastrectomy, cause significant ongoing bone loss. In resources available to the general public and to physicians, this adverse outcome is rarely mentioned or is attributed solely to reduced calcium absorption...

BACKGROUND: Bariatric surgery is the most effective long-term weight loss method. The most common procedures are Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG). Bariatric patients are at high risk of vitamin D deficiency (VDD) and insufficiency (VDI), which are associated with skeletal and nonskeletal ailments. There is no consensus regarding the optimal treatment for VDD/VDI in bariatric patients. OBJECTIVES: To critically examine the literature on vitamin D status (serum 25[OH]D concentrations) pre- and postbariatric surgery as well as supplementation regimens currently used...

BACKGROUND: Bariatric surgery represents an efficient treatment of morbid obesity allowing not only weight loss but also the control of comorbidities related to obesity. Although the sleeve gastrectomy and gastric bypass are currently the two most common procedures, the superiority of one over another and the indications remain imprecise. AIM: The aim of this work was to provide an evidence based answer to the following questions: What is the most efficient surgical procedure: gastric bypass or sleeve gastrectomy regarding weight loss, postoperative morbidity and remission of comorbidities related to obesity? METHODS: A literature search has been conducted in the data bases of Pubmed, Cochrane Library and Scopus during the period between January 2008 to March 2015, with the keywords "Gastric Bypass" and "Sleeve Gastrectomy"...

INTRODUCTION: After all bariatric procedures, multivitamin supplements are uniformly prescribed to minimize eventual deficiencies. These supplements are usually maintained long time, even during the whole life after malabsorptive techniques, while these are maintained at least during 1 year after restrictive procedures. Given that sleeve gastrectomy does not alter intestinal absorption, the supplements are possibly unnecessary, once the patient can take an adequate diet. PATIENTS AND METHODS: A prospective randomized study of patients undergoing a laparoscopic sleeve gastrectomy was performed...

BACKGROUND: Two main causes for nutrient deficiencies following bariatric surgery (BS) are pre-operative deficiencies and favoring foods with high-energy density and poor micronutrient content. The aims of this study were to evaluate nutritional status and gender differences and the prevalence of nutritional deficiencies among candidates for laparoscopic sleeve gastrectomy (LSG) surgery. METHODS: A cross-sectional analysis of pre-surgery data collected as part of a randomized clinical trial on 100 morbidly obese patients with non-alcoholic fatty liver disease (NAFLD) admitted to LSG surgery at Assuta Medical Center between February 2014 and January 2015...

Laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are common and effective methods to treat severe obesity, but these procedures can adversely influence bone metabolism and areal bone mineral density (aBMD). This was a prospective 24-month single-center interventional two-arm study in 220 women and similarly aged men (median age 40.7 years) with a body mass index (BMI) >38 kg/m(2) after RYGB and SG procedures. Patients were randomized into: 1) an intervention group receiving: 28,000 IU cholecalciferol/wk for 8 weeks before bariatric surgery, 16,000 IU/wk and 1000 mg calciummonocitrate/d after surgery, daily BMI-adjusted protein supplementation and physical exercise (Nordic walking, strength perseverance, and equipment training); 2) a non-intervention group: no preoperative loading, nutritional supplementation, or obligatory physical exercise...

BACKGROUND: Duodenal diverted sleeve gastrectomy with ileal interposition (DDSG-II) is a bariatric-metabolic operation designed to treat type 2 diabetes mellitus (T2DM). It is restrictive (SG) but also acts on the small bowel with functional effects. The objective of the present study was to investigate whether or not it is also a malabsorptive operation. METHODS: Twelve obese patients (9 female and 3 male) affected by T2DM had DDSG-II. Follow-up was every 3 months, and the results after 1 year are reported here...

BACKGROUND: We assessed the need of vitamin D supplementation to achieve normal 25-hydroxyvitamin D (25[OH]D) levels after bariatric surgery and whether there were differences between laparoscopy sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS: A total of 164 morbid obese patients undergoing bariatric surgery from January 2008 to June 2011 were followed for 2 years. Serum levels of 25(OH)D and intact parathyroid hormone (iPTH) were measured preoperatively and at 3, 6, 9, 12, 18, and 24 months after operation...
