OBJECTIVES: Despite the fact that the most effective treatment for morbid obesity today is gastric bypass surgery, some patients develop life-threatening nutritional complications associated with their weight loss. METHODS: Here we examine the influence of the altered anatomy and digestive physiology on pancreatic secretion and fat absorption. Thirteen post Roux-en-Y gastric bypass (RYGB) patients who had lost >100 lbs in the first year following surgery and who gave variable histories of gastrointestinal (GI) dysfunction, were selected for study...

BACKGROUND: Serial changes in dietary intake, including specific food groups and nutrients during the first year following Roux-en-Y gastric bypass (RYGB) are of interest due to surgically induced alterations in meal size, food intolerances present after surgery, and potential nutrient deficiencies. To help improve the nutritional health of surgical patients, this study's purpose was to examine changes in macro- and micronutrients, food groups, and selected foods during 12 months of follow-up in post-RYGB individuals...

OBJECTIVE: The effects of food tolerance (if any) on diet quality several years post-surgery remain unclear. Our study aimed to assess food tolerance and diet quality after three bariatric procedures; adjustable gastric banding (AGB), sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGBP), 2â??4 years post-surgery. METHODS: This prospective, cross-sectional study assessed weight loss, food tolerance and diet quality in 130 subjects (14 obese pre-surgical controls, 13 AGB, 62 SG and 41 RYGBP)...

BACKGROUND: Severe, drug-resistant gastroparesis is a debilitating condition. Several, but not all, patients can get significant relief from nausea and vomiting by gastric electrical stimulation (GES). A trial of temporary, endoscopically delivered GES may be of predictive value to select patients for laparoscopic-implantation of a permanent GES device. MATERIALS AND METHODS: We conducted a clinical audit of consecutive gastroparesis patients, who had been selected for GES, from May 2008 to January 2012...

BACKGROUND: Advances in bariatric surgery have brought about a paradigm shift in the management of obesity, with benefits extending beyond weight loss. However, nutritional deficiencies are an inherent problem in the postoperative period and often require lifelong supplementation. Vitamin B12, also referred to as cobalamin, is one of the most common micronutrient deficiencies affecting this population. This review explores the pathophysiology of cobalamin deficiency in patients undergoing bariatric surgery and provides an overview of the effectiveness of various available vitamin B12 formulations...

BACKGROUND/OBJECTIVES: The main objective was to test the hypothesis that dietary energy density (DED) decreases after Roux-en-Y gastric bypass (gastric bypass). SUBJECTS/METHODS: A total of 43 patients (31 women and 12 men) aged 43 (s.d. 10) years, with body mass index (BMI) 44.3 kg/m(2) (4.9), were assessed preoperatively at 6 weeks and 1 and 2 years after gastric bypass. Self-reported energy intake (EI), food weight (FW) and food choice were assessed using a dietary questionnaire...

Changes in the anatomy and function of the gastrointestinal tract after bariatric surgery markedly change patients' eating patterns. Malnutrition is a significant risk associated with all bariatric procedures, which can lead to dangerous nutritional deficiencies. However, if correct patient selection is conducted and if patients receive thorough preoperative nutrition education and postoperative nutritional follow-up, these deficiencies are largely preventable. Nurses are important members of the multidisciplinary team; assisting in patient selection, providing hands-on care, and educating the patient on the surgical process and post-operative dietary restrictions...

BACKGROUND: Patients' inability to take oral nutrition calls for alternative feeding. In selected pediatric patients, traditional feeding tubes are not tolerated and jejunal feeding tubes can be obstructive. One option is a Roux-en-Y feeding limb. Our institution noted complications secondary to small bowel volvulus around this limb. Goals of this study were to review patients who experienced volvulus after Roux-en-Y creation, and to identify factors contributing to this complication...

The frequency of bariatric surgery has increased markedly in France in recent years, partly due to a better appreciation of the problem of morbid obesity but also due to the commercial introduction of adjustable gastric banding devices which can be placed by laparoscopic approach. Numerous complications of this surgery are known and require recognition to be appropriately treated. Studies of complications suffer from selection bias, methodologic flaws, and lack of follow-up. The incidence and type of complication are affected by the learning curve and surgical techniques...

In this study, we have analyzed a series of 88 patients who underwent total gastrectomy followed by two different reconstructive procedures, Roux-en-Y jejunal interposition (57%) and interposition of a jejunal limb between the oesophagus and the duodenum (38%) (Henley procedure). We examined diet, intestinal transit, symptoms of dumping syndrome and body weight curves. Patients with Roux-en-Y reconstruction presented post-prandial sweating more often (48%) than patients with the Henley procedure (21%). Forty percent patients with Roux-en-Y reconstruction suffered post-prandial nausea whereas this finding was not associated with patients after the Henley procedure...
