Sleeve gastrectomy and nutrition

PURPOSE: Our aim in this study is to assess single anastomosis duodeno-ileal bypass (SADI) as a salvage procedure following sleeve gastrectomy (SG), examining its technical feasibility, outcomes, and potential complications. MATERIALS AND METHODS: A systematic review and meta-analysis were conducted, drawing data from PubMed, Medline, and the Cochrane library. The analysis encompassed 14 studies, involving 1,066 patients. We evaluated operative time, comorbidity resolution (hypertension, dyslipidemia, diabetes), post-operative diarrhea incidence, excess weight loss (EWL) at six, twelve, and twenty-four months, and post-operative leak rates...

BACKGROUND: Malnutrition and liver impairment after duodenal switch (DS) are possible and undesired complications, often conservatively treated. However, in specific cases, surgical revision may be necessary. This study aims to describe outcomes achieved by two bariatric surgery centers and address effectiveness and safety of revisional surgical procedures to resolve these complications. METHODS: A retrospective chart review was performed in two bariatric surgery centers from 2008 to 2022...

PURPOSE: Despite lifestyle changes and medication therapies, weight loss is difficult to maintain. Metabolic and bariatric surgery (MBS) is an effective route for significant weight reduction. However, post-operation there are limited opportunities to support weight loss maintenance. The following study aimed to pilot test a 6-week, 6-session nutrition and support program for post-MBS surgery patients. MATERIALS AND METHODS: A 6-week post-MBS pilot nutrition and support program was developed to test feasibility and acceptability...

OBJECTIVE: Excessive obesity can lead to dysfunction in adipose tissue, which contributes to the development of comorbidities associated with obesity, such as type 2 diabetes (T2D), cardiovascular and cerebrovascular disease, among others. Previous research has mainly focused on the Vanin family in systemic inflammatory diseases or predicting its role in tumor prognosis, while neglecting its role as a secretory protein in adipose tissue inflammation and metabolism. The objective of this study was to compare the changes in Vanin-2 levels in the circulating blood of normal and obese individuals, and to assess its correlation with inflammatory factors in vivo ...

BACKGROUND: Obesity is a global epidemic and is associated with cognitive impairment and dementia. It remains unknown whether weight loss interventions, such as bariatric surgery, can mitigate cognitive impairment. OBJECTIVES: We aimed to determine the effect of surgical weight loss on cognition in individuals with class II/III obesity. DESIGN: We performed a prospective cohort study of participants who underwent bariatric surgery. At baseline and two years following surgery, participants completed metabolic risk factor and neuropsychological assessments...

BACKGROUND: Obesity is a global health concern associated with a plethora of chronic diseases. Genetic and lifestyle factors play a pivotal role in its development, making it a significant challenge for healthcare systems worldwide. In this context, sleeve gastrectomy has emerged as a prominent bariatric surgical intervention, but the level of awareness and knowledge regarding its indications and complications in the Eastern Province of Saudi Arabia is underexplored. METHODS: This descriptive cross-sectional study was conducted over one year, from January 2022 to December 2022...

INTRODUCTION: Persons living with obesity treated with bariatric surgery are at a high risk of developing nutritional deficiencies. The primary aim of this observational cohort study was to compare vitamin D levels in patients two years after bariatric surgery (Roux-en-Y gastric bypass/RYGB and sleeve gastrectomy/SG) with a very low-energy diet (VLED). The same subjects were also compared with a population sample from the same region at baseline. The primary hypothesis was that surgery, especially RYGB, would lead to an increased prevalence of vitamin D deficiency compared to subjects treated with VLED...

BACKGROUND: Urolithiasis, a common clinical condition, has seen a global increase in prevalence in recent years. Urinary stones are common in hot climate areas like Saudi Arabia. This study aimed to assess the prevalence and awareness of risk factors for urinary stones in Jazan, Saudi Arabia. METHODS: A cross-sectional study was conducted among 1000 Jazan adults between January and June 2022. A questionnaire was used to collect data on sociodemographics, urinary stone diagnosis, and awareness of risk factors...

BACKGROUND: The relationship between lipid mediators and severe obesity remains unclear. Our study investigates the impact of severe obesity on plasma concentrations of oxylipins and fatty acids and explores the consequences of weight loss. METHODS: In the clinical trial identifier NCT05554224 study, 116 patients with severe obesity and 63 overweight/obese healthy controls matched for age and sex (≈2:1) provided plasma. To assess the effect of surgically induced weight loss, we requested paired plasma samples from 44 patients undergoing laparoscopic sleeve gastrectomy one year after the procedure...

Bariatric surgery has emerged as a highly effective option for individuals with obesity, offering significant and sustainable weight loss outcomes. This surgical approach involves various procedures that alter the anatomy of the gastrointestinal tract, leading to reduced food intake and nutrient absorption. Established procedures such as sleeve gastrectomy, gastric bypass, adjustable gastric banding, and biliopancreatic diversion with duodenal switch have proven track records. In contrast, emerging options like intragastric balloons, AspireAssist devices, and endoscopic sleeve gastroplasty show promise but require further investigation...

Obesity is a global public health crisis associated with numerous medical conditions and increased mortality rates. Weight loss surgery, or bariatric surgery, has become a crucial treatment option for clinically severe obesity. Bariatric surgery is an effective treatment for severe obesity but it carries the potential for various complications, both in the short and long term. This article provides a comprehensive overview of these complications, aiding healthcare professionals in their management and patients in understanding the risks associated with bariatric surgery...

(1) Background: studies have shown that some patients experience mental deterioration after bariatric surgery. (2) Methods: We examined whether the use of probiotics and improved eating habits can improve the mental health of people who suffered from mood disorders after bariatric surgery. We also analyzed patients' mental states, eating habits and microbiota. (3) Results: Depressive symptoms were observed in 45% of 200 bariatric patients. After 5 weeks, we noted an improvement in patients' mental functioning (reduction in BDI and HRSD), but it was not related to the probiotic used...

The long-term effects and safety of single-anastomosis sleeve ileal (SASI) bypass have not been confirmed. The one anastomosis procedure carries the risk of bile reflux, and Braun anastomosis has the capacity to reduce bile reflux. This study was designed to compare the influences of bile reflux and histological changes in the esogastric sections of rats. Obese Sprague-Dawley rats underwent sleeve gastrectomy with transit bipartition (RYTB) (n = 12), SASI (n = 12), SASI bypass with Braun anastomosis (BTB) (n = 12), esojejunostomy (EJ) (n = 12), and SHAM (n = 8) surgery...

IMPORTANCE: Obesity affects approximately 42% of US adults and is associated with increased rates of type 2 diabetes, hypertension, cardiovascular disease, sleep disorders, osteoarthritis, and premature death. OBSERVATIONS: A body mass index (BMI) of 25 or greater is commonly used to define overweight, and a BMI of 30 or greater to define obesity, with lower thresholds for Asian populations (BMI ≥25-27.5), although use of BMI alone is not recommended to determine individual risk...

Bariatric surgery, including sleeve gastrectomy (SG), improves systolic and diastolic function, which is independent of weight loss in rodent models. The cause of weight loss-independent improvements in cardiac function are unknown but may originate from the gastrointestinal tract. In this study, we investigated whether a circulating blood factor is a mechanism for acute cardioprotection after SG by testing the utility of rodent SG plasma to reduce metabolic stress in vitro. For the initial experiment, obese male Zucker rats underwent SG, ad lib sham, or pair-fed sham surgeries (n = six SG, n = eight SH, n = eight PF)...

BACKGROUND: The incidence and impact of hypoalbuminemia in bariatric surgery patients is poorly characterized. We describe its distribution in laparoscopic sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) patients undergoing primary or revision surgeries and assess its impact on postoperative complications. METHODS: The Metabolic and Bariatric Surgery Quality Improvement Program Database (2015 to 2021) was analyzed. Hypoalbuminemia was defined as Severe (< 3 g/dL), Moderate (3 ≤ 3...

BACKGROUND: Bariatric surgery (BS) may result in inadequate nutrient intake and poor diet quality, which can lead to nutritional complications. The present study aimed to evaluate changes in macro- and micronutrient composition and diet quality in the first 6 months following BS. METHODS: One hundred seven participants undergoing BS (Roux-en-Y gastric bypass: n = 87, sleeve gastrectomy: n = 20) completed 3-day food records before and 6 months after surgery...

This review focuses on providing physicians with insights into the complex relationship between bone marrow adipose tissue (BMAT) and bone health, in the context of weight loss through caloric restriction or metabolic and bariatric surgery (MBS), in people living with obesity (PwO). We summarize the complex relationship between BMAT and bone health, provide an overview of noninvasive imaging techniques to quantify human BMAT, and discuss clinical studies measuring BMAT in PwO before and after weight loss. The relationship between BMAT and bone is subject to variations based on factors such as age, sex, menopausal status, skeletal sites, nutritional status, and metabolic conditions...

Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy characterized by simple operation and few postoperative complications have gradually become the two most commonly used surgical methods in clinical practice.A series of complications often occur after bariatric surgery,including gallstone disease,anemia,malnutrition,gastroesophageal reflux disease,kidney stones,and birth defects in offspring of women of childbearing age.There are controversies regarding the causes and countermeasures of these complications...

Severe malnutrition following one-anastomosis gastric bypass (OAGB) remains a concern. Fifty studies involving 49,991 patients were included in this review. In-hospital treatment for severe malnutrition was needed for 0.9% (n = 446) of patients. Biliopancreatic limb (BPL) length was 150 cm in five (1.1%) patients, > 150 cm in 151 (33.9%), and not reported in 290 (65%) patients. OAGB was revised to normal anatomy in 126 (28.2%), sleeve gastrectomy in 46 (10.3%), Roux-en-Y gastric bypass in 41 (9...
