Purpose: Severe obesity can increase risk of complications after kidney transplantation. There is a paucity of literature on bariatric surgery outcomes in renal transplant candidates. The objective of this study was to analyze outcomes of bariatric surgery as a weight reduction strategy for patients with kidney failure to enhance eligibility for kidney transplantation. Read More

Purpose: Bariatric surgery is the most effective treatment of morbid obesity. Bariatric procedures employ different mechanisms of action to induce weight loss. The present study aimed to compare single-anastomosis sleeve ileal (SASI) bypass and roux-en-Y gastric bypass RYGB with long biliopancreatic limb (BPL) in terms of weight loss, remission of comorbidities, complications, and nutritional status.

Background: Obesity, a major global health problem, is associated with increased cardiometabolic morbidity and mortality. Protein glycosylation is a frequent posttranslational modification, highly responsive to inflammation and ageing. The prospect of biological age reduction, by changing glycosylation patterns through metabolic intervention, opens many possibilities. Read More

Background: New Zealand health services are responsible for equitable health service delivery, particularly for Māori, the Indigenous peoples of New Zealand. Recent research has indicated the presence of inequities in publicly funded bariatric surgery in New Zealand by ethnicity, but it is unclear whether these inequities persist after adjustment for co-morbidities.

Objectives: To determine whether receipt of publicly funded bariatric surgery varies by ethnicity, after adjustment for co-morbidities. Read More

Background: Uncoupling protein 2 (UCP2) plays an important role in energy expenditure regulation. Previous studies have associated the common -866G/A (rs659366) and Ins/Del polymorphisms in the UCP2 gene with metabolic and obesity-related phenotypes. However, it is still unclear whether these polymorphisms influence weight loss after bariatric surgery. Read More

Determining which patients will benefit from bariatric surgery is complex; however, in those who have had previous bariatric surgery or extensive abdominal surgery, this can be particularly challenging. Decisions are often made based on assumptions rather than a complete assessment of all the anatomical and physiological factors. Adopting the approach utilised in gastrointestinal surgery with a diagnostic or staging laparoscopy, it may be possible to more accurately stage disease and determine fitness bariatric surgery.

Background: Marginal ulceration (MU) and bleeding are possible complications following laparoscopic Roux-en-Y gastric bypass (RYGB). Our institution utilizes three techniques for performing the gastrojejunal anastomosis (GJA), providing a means to compare postoperative MU and bleeding as it relates to GJA technique.

Objectives: We sought to analyze the incidence of MU and bleeding between the 25-mm end-to-end anastomosis (EEA) stapler, linear stapler (LS), and robotic hand-sewn (RHS) GJA techniques. Read More

The micronutrient status and optimal monitoring schedule after bariatric surgery have not been sufficiently assessed. This systematic review and meta-analysis investigated the longitudinal changes in micronutrient status after bariatric surgery. PubMed, EMBASE, and Cochrane Library were searched for articles that measured preoperative and postoperative serum micronutrient levels in patients undergoing Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG).

Background: The simultaneous assessment of visceral adiposity and muscle mass might be useful to monitor the risk of non-alcoholic fatty liver disease (NAFLD) progression in large population. We aimed to investigate the value of serum creatinine-to-cystatin C ratio (CCR) in evaluating these two parameters and predicting liver steatosis and fibrosis.

Methods: 154 overweight/obese inpatients (49 males, 105 females) scheduled for bariatric surgery and 49 non-overweight/obese volunteers (18 males, 31 females) responded to the hospital advertisement were involved in the cross-sectional study. Read More

 The present study aims to evaluate the prevalence of foot and ankle pain complaints, radiographic parameters, and functional performance in subjects with severe obesity (body mass index [BMI] > 40) who are candidates to bariatric surgery.  Forty severely obese patients were evaluated at a bariatric surgery outpatient facility. These severely obese subjects (BMI > 40) were divided into two subgroups: those with BMI < 50 (n = 24) and BMI > 50 (n = 16). Read More

Purpose: Food addiction (FA) following bariatric surgery (BS) has received a burst of attention in recent years due to its important contribution to obesity. Therefore, this study was conducted to explore the prevalence of FA disorder and its predictors 2 years after laparoscopic sleeve gastrectomy (LSG) and assess its relationship with physical activity (PA), body composition, and weight outcomes.

Materials And Methods: Four hundred fifty individuals who had undergone LSG 2 years prior to the study were enrolled. Read More

Obesity is a growing burden to health and the economy worldwide. Obesity is associated with central µ-opioid receptor (MOR) downregulation and disruption of the interaction between MOR and dopamine D receptor (DR) system in the ventral striatum. Weight loss recovers MOR function, but it remains unknown whether it also recovers aberrant opioid-dopamine interaction. Read More

Background & Aims: Human beings are often driven to exhibit dietary preference according to their hedonic characteristics. Though previous studies proposed that the fat taste preference of an obese individual was associated with BMI, the perception of fat taste differs for every individual. The genetic variation among populations in taste receptor genes such as CD36 may be a contributing factor for this difference. Read More

Background & Aims: Owing to the "obesity-pandemic", an increasing number of individuals are in need of treatment for obesity and obesity-related disorders. For patients with severe disease, results with conventional treatment modalities such as diet regimens, physical activity, and pharmacologic agents most often lack satisfactory efficacy and/or sustainability. In contrast, bariatric surgery has been demonstrated to be associated with marked, long-term weight loss as well as resolution or improvement of co-morbid disease, in particular metabolic aberrations such as insulin resistance and type 2 diabetes.

Background: Gastrointestinal Stromal Tumors (GISTs) are rare sarcomas with 5000 new cases arising in the United States each year. Despite their low incidence, general surgeons should be familiar with GISTs since a quarter of these neoplasms are encountered incidentally.

Methods: A retrospective medical records review was conducted to create a database of all GISTs resected from January 2005 to May 2019. Read More

Background: The mechanisms of weight loss and metabolic improvements following bariatric surgery in skeletal muscle are not well known; however, epigenetic modifications are likely to contribute. The aim of our study was to investigate skeletal muscle DNA methylation after weight loss induced by Roux-en-Y gastric bypass (RYGB) surgery. Muscle biopsies were obtained basally from seven insulin-resistant obese (BMI > 40 kg/m) female subjects (45. Read More

Purpose: Prior cross-sectional research details the high rate of impaired family functioning, a measure of the overall family environment, among adult bariatric surgery patients; however, family functioning has not been explored in relation to adult patient's postoperative outcomes. The objective of this study was to determine how family functioning affects postoperative patient outcomes including readmission rates, early complications, and 6- and 12-month percent total weight loss (%TWL).

Materials And Methods: An observational design at a single-academic medical center was employed. Read More

Background And Objective: Bariatric surgery is a major event associated with psychological changes such as improvements in self-esteem, increased autonomy, and better self-value. Such changes could affect the patient's interpersonal relationships; however, little is known about the impact of bariatric surgery on changes in relationship status. In this paper, we aim to test the hypothesis that bariatric surgery is associated with changes in interpersonal relationships such as becoming single for those who were in a relationship or entering a relationship among those who were single before surgery.
