BACKGROUND: - Bariatric surgery is the most effective treatment for severe obesity, but the surgery increases the risk of developing nutritional deficiencies, such as vitamin A deficiency. In human metabolism, vitamin A plays a role in vision. OBJECTIVE: - To evaluate serum vitamin A, visual function and ocular surface of patients undergoing bariatric surgery. METHODS: - A cross-sectional and analytical study was conduced with 28 patients undergoing bariatric surgery for at least 6 months...

BACKGROUND: Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservatively treated adolescents and of adults undergoing Roux-en-Y gastric bypass, in the Adolescent Morbid Obesity Surgery (AMOS) study...

OBJECTIVE: To explore the support needs and experiences of patients who had received publicly or privately funded bariatric surgery and the importance of this support in mediating outcomes of surgery. METHODS: Seven semi-structured focus groups were conducted. A broad interview schedule guided the discussions which were audio-recorded and transcribed verbatim. Data were analysed thematically. RESULTS: Twenty-six women and 15 men with a mean age of 54 years (range 24-72) participated in the study...

BACKGROUND: Biliopancreatic diversion with duodenal switch (BPD/DS) is the most effective bariatric surgical procedure, but major concerns exist about the nutritional consequences. OBJECTIVES: The study reported weight loss and nutritional outcomes of 80 patients with a follow-up of at least 10 years. SETTING: The follow-up was conducted at a university hospital as well as in a private practice institution in France. METHODS: Eighty patients operated on between February 2002 and May 2006 were reviewed...

Anne L Schafer
Bariatric surgery is a highly effective treatment for obesity, but it may have detrimental effects on the skeleton. Skeletal effects are multifactorial but mediated in part by nutrient malabsorption. While there is increasing interest in non-nutritional mechanisms such as changes in fat-derived and gut-derived hormones, nutritional factors are modifiable and thus represent potential opportunities to prevent and treat skeletal complications. This review begins with a discussion of normal intestinal calcium transport, including recent advances in our understanding of its regulation by vitamin D, and areas of continued uncertainty...

: The transmembrane 6 superfamily member 2 (TM6SF2) loss-of-function variant, rs58542926, is a genetic risk factor for nonalcoholic fatty liver disease and progression to fibrosis, but is paradoxically associated with lower levels of hepatic-derived triglyceride-rich lipoproteins (TRLs). TM6SF2 is expressed predominately in liver and small intestine, sites for triglyceride rich lipoprotein biogenesis and export. In light of this, we hypothesized that TM6SF2 may exhibit analogous effects on both liver and intestine lipid homeostasis...

The significant increase in the prevalence of obesity has led to an increase in the number of obese women who become pregnant. In this setting, in recent years, there has been an exponential rise in the number of bariatric procedures, with approximately half of them performed in women of childbearing age, and a remarkable surge in the number of women who become pregnant after having undergone bariatric surgery (BS). These procedures entail the risk of nutritional deficiencies, and nutrition is a crucial aspect during pregnancy...

Bezoars are collections of undigested foreign material that accumulate in the gastrointestinal tract. The most common are phytobezoars, which are formed from plant fibers, especially those related to the ingestion of persimmon. Patients who undergo abdominal surgery, including bariatric surgery for obesity, and particularly gastrectomy, are prone to bezoar formation due to reduced gastric motility, loss of pyloric function, and hypoacidity. Bezoars can form months to years postoperatively. Our objective was to review the published literature regarding phytobezoar formation after bariatric surgery...

INTRODUCTION: Wernicke's encephalopathy (WE) is a neurological syndrome caused by thiamine deficiency, and clinically characterized by ophthalmoplegia, ataxia and acute confusion. In developed countries, most cases of WE have been seen in alcohol misusers. Other reported causes are gastrointestinal tract surgery, hyperemesis gravidarum, chronic malnutrition, prolonged total parenteral nutrition without thiamine supplementation, and increased nutrient requirements as in trauma or septic shock...

OBJECTIVE: Laparoscopic sleeve gastrectomy has become one of the most commonly performed bariatric operations. It is essentially a restrictive bariatric operation; however, a series of hormonal changes occurring postoperatively contribute to decreased appetite and reduced food intake. PATIENTS AND METHODS: This is a literature review of recent articles published on Pubmed, Medline and Google Scholar databases in English. RESULTS: Although, laparoscopic sleeve gastrectomy is commonly performed worldwide, there is still a lack of standardization regarding the surgical technique...

Lifelong monitoring after weight loss surgery is recommended in order to check the efficacy of the procedure and to identify complications. Particular attention must be paid to the nutritional status of pregnant women and in the event of surgical complications. Education programmes must be offered at every stage of the care pathway in order to favour the compliance required for the follow-up.

Surgical treatment of obesity, also called "bariatric surgery", is the reference treatment for severe and morbid forms of obesity after proper multidisciplinary medical treatment has failed. However, it is only one step in the pathway of the obese patient and should only be envisaged in the framework of lifelong nutritional care.

BACKGROUND/OBJECTIVES: Most bariatric guidelines recommend frequent lab monitoring of patients to detect nutrient and vitamin deficiencies as early as possible. The aim of this study was to optimize the cost effectiveness of the nutrient panel, by developing an algorithm, which detects nutrient deficiencies at lower costs. SUBJECTS/METHODS: In this retrospective study, 2055 patients who had undergone Laparoscopic Roux-Y Gastric Bypass (LRYGB) and Laparoscopic Sleeve Gastrectomy (LSG) surgery at Catharina Hospital Eindhoven between January 2009 and December 2013 were included...

Roughly 1% of all weight loss surgery is performed in adolescents. There is strong evidence demonstrating significant postsurgical weight loss, improvement in quality of life, and reduction in comorbidities such as hypertension and diabetes. Reports of postoperative complications in adolescents are few because of the small sample size in most series. Despite vitamin supplementation, nutritional deficiencies requiring hospitalization occur occasionally after Roux-en-Y gastric bypass. Wernicke encephalopathy, a triad of ophthalmoplegia, ataxia, and altered mental status, is a serious consequence of thiamine (vitamin B1) deficiency...

Obesity is one of the most important public health conditions worldwide. Bariatric surgery for severe obesity is an effective treatment that results in the improvement and remission of many obesity-related comorbidities, as well as providing sustained weight loss and improvement in quality of life. Contemporary bariatric operations include Roux-en-Y gastric bypass, sleeve gastrectomy, adjustable gastric band and the duodenal switch. The vast majority of these procedures are now performed using laparoscopic technique, the main advantages of which include rapid recovery, the reduction of postoperative pain and the reduction of wound-related complications, compared with open surgery...

BACKGROUND: Biliopancreatic diversion (BPD) is a bariatric technique burdened, in some instances, by clinical evidence of malabsorption and malnutrition, and by intractable diarrhea. OBJECTIVE: The objective of this study was to assess metabolic and nutritional effects on patients undergoing BPD and BPD plus revisional surgery because of side effects. METHODS: Thirty-five consecutive BPD patients underwent revisional surgery (elongation of the common limb from 50 to 200 cm and reduction of the gastric pouch from 500 to 40 ml) after a median 48-month period [48...
