: Nonalcoholic steatohepatitis (NASH) affects 2-3% of the U.S. population and is expected to become the leading indication for liver transplantation in the next decade. Bariatric surgery may be an effective but expensive treatment for NASH. Using a state-transition model, our analysis aimed to assess the effectiveness and cost-effectiveness of surgery to manage NASH. We simulated the benefits and harms of laparoscopic Roux-en-Y gastric bypass surgery in patients defined by weight class (overweight, mild obesity, moderate obesity, and severe obesity) and fibrosis stage (F0-F3)...

INTRODUCTION: Obesity is a contributor to the global burden of chronic diseases, including non-alcoholic fatty liver disease and non-alcoholic steatohepatitis (NASH). NASH cirrhosis is becoming a leading indication for liver transplant (LT). Obese transplanted patients have higher morbidity and mortality rates. One strategy, to improve the outcomes in these patients, includes bariatric surgery at the time of LT. Herein we report the first European combined LT and sleeve gastrectomy (SG)...

Obesity is associated with worse short-term outcomes after kidney transplantation but the effect on long-term outcomes is unknown. Although some studies have reported worse outcomes for obese recipients when compared to recipients with a BMI in the normal range, obese recipients who receive a transplant have better outcomes than those who remain wait-listed. Whether transplant candidates should be advised to lose weight before or after transplant has been debated and this is mainly due to the gap in the literature linking pre-transplant weight loss with better outcomes post-transplantation...

BACKGROUND: Enteric hyperoxaluria (EH) occurs with a rate of 5-24% in patients with inflammatory bowel disease, ileal resection and modern bariatric surgery. The excessive absorption of calcium oxalate causes chronic kidney disease (CKD) in patients with EH. In the literature, a single experience was reported in combined intestine-kidney transplantation (CIKTx) in patients with CKD due to EH. METHODS: After a report of 2 successful cases of CIKTx in patients with EH and CKD, one was performed at our center in a 59-year-old Caucasian female who developed intestinal failure with total parenteral nutrition (TPN) dependence after a complication post-bariatric surgery...

PURPOSE OF REVIEW: Advances in surgical technique and immunosuppression have significantly improved outcomes after pancreas transplantation, and as a result pancreas transplants increasingly are being performed for indications other than type 1 diabetes mellitus. This review summarizes the current literature on pancreas transplantation in unconventional recipient populations. RECENT FINDINGS: An increasing body of work suggests that pancreas transplantation can be performed with good outcomes in patients with type 2 diabetes mellitus and those 50 years of age and older...

Morbid obesity affects the function of the transplanted heart either directly, by damaging many elements that affect cardiac function or indirectly, by the initial appearance or worsening of co-morbidities that affect the heart. Bariatric surgery is the most effective treatment for a significant and sustained decrease in weight and it leads to the disappearance of co-morbidities such as diabetes, hypertension and dyslipidemia in high rates. These diseases can damage the blood vessels of the graft and impair its function...

In kidney transplantation, obesity is associated with poorer graft survival and patient survival. Bariatric surgery may provide benefit for these patients, not only by inducing weight loss, but also via reduction of diabetes. We report a case of morbid obesity, poorly controlled new-onset diabetes mellitus, and gout after kidney transplantation that was treated with laparoscopic sleeve gastrectomy 3 years after kidney transplantation. After 1 year of follow-up, 76% excessive body weight loss was attained. No complications were noted...

INTRODUCTION: In extreme obesity, bariatric surgery or weight loss by lifestyle modification is often not possible because of presence of decompensated cirrhosis. Endoscopic intragastric balloon placement may be used as minimal invasive technique to promote weight loss and make them better candidates for liver transplantation surgery; however, there is no literature in this regard. METHODS: Patients with body mass index (BMI) >40 kg/m(2) or BMI between 35 and 40 (with a low graft to recipient weight ratio) were considered for weight reduction modalities including dietary counseling and intragastric balloon placement when feasible...

BACKGROUND: Obesity is a risk factor for development of left ventricular systolic dysfunction (LVSD) and can complicate LVSD management, especially for individuals in whom cardiac transplantation is indicated. Bariatric surgery is increasingly recognized as a safe and effective intervention to achieve marked weight loss, but experience is limited in the LVSD population. METHODS AND RESULTS: We retrospectively reviewed patients with obesity and left ventricular ejection fraction (LVEF) <50% who underwent bariatric surgery at a tertiary center 2004 to 2013...

Obesity is common amongst patients with renal transplants (RT). It is associated not only with generic obesity-related complications including diabetes, but also with higher rates of graft rejection and loss. A Best Evidence Topic in surgery was written according to a structured protocol: this is a systematic review of the literature, suitable when the quality of available evidence is low. The question addressed was: is weight-loss surgery (WLS) safe and effective in patients that have had a previous renal transplant? Three prospective case series and one multicentre retrospective study were identified, together reporting on a total of 112 patients who underwent WLS after RT...

PURPOSE OF REVIEW: Nonalcoholic steatohepatitis (NASH) is projected to become the most common indication for liver transplantation in the near future. NASH recipients have concurrent obesity, metabolic, and cardiovascular risks, which directly impact patient selection, posttransplant morbidity and potentially long-term outcomes. The purpose of this review is to highlight strategies to optimize pretransplant selection, outcomes, and posttransplant risk modification to optimize patient and graft survival...

BACKGROUND: Among organ transplant recipients, a common side effect of immunosuppressive therapy is the development of obesity, which affects a third of the patients within 3 years after transplantation. Bariatric surgery represents a possible surgical option for weight loss among posttransplant patients. OBJECTIVES: The aim of this study was to examine percent excess weight loss (%EWL), and percent weight loss (%WL) and perioperative and postoperative complications in posttransplant obese patients after sleeve gastrectomy (SG) compared with nontransplant patients...

Nonalcoholic fatty liver disease (NAFLD) is the most common etiology of chronic liver disease in developed countries and is on trajectory to become the leading indication for liver transplantation in the USA and much of the world. Patients with NAFLD cirrhosis awaiting liver transplant face unique challenges and increased risk for waiting list stagnation and dropout due to burdensome comorbidities including obesity, diabetes, cardiovascular disease, and kidney disease. Thus far, patients transplanted for NAFLD cirrhosis have excellent mid- and long-term patient and graft survival, but concerns regarding short-term morbidity and mortality continue to exist...

BACKGROUND: Cardiopulmonary exercise testing (CPET) is used as a preoperative risk-stratification tool for patients undergoing non-cardiopulmonary intra-abdominal surgery. Previous studies indicate that CPET may be beneficial, but research is needed to quantify CPET values protective against poor postoperative outcome [mortality, morbidity, and length of stay (LOS)]. METHODS: This systematic review aimed to assess the ability of CPET to predict postoperative outcome...

INTRODUCTION: It has been reported in the literature that upper gastrointestinal malignancies after bariatric surgery are mostly gastro-esophageal, although it is not clear whether bariatric surgery represents a risk factor for the development of esophageal and/or gastric cancer. We report a case of a de novo gastric adenocarcinoma occurring in a transplant patient 1 year after a laparoscopic sleeve gastrectomy. PRESENTATION OF CASE: A 44 year-old woman with a BMI of 38kg/m(2), hypertension, type 1 diabetes mellitus, multiple malignancies and a pancreas transplant underwent laparoscopic sleeve gastrectomy...

There is no single pharmacologic therapy that has been approved to treat nonalcoholic fatty liver disease in the general population. The backbone of therapy currently includes intensive lifestyle modification with established targets for diet and weight loss. The use of unsweetened, unfiltered coffee along with limiting high fructose corn syrup have emerged as beneficial dietary recommendations. The use of empiric oral hypoglycemic agents and vitamin E, however, has not been widely accepted. Developing bariatric surgical techniques are promising, but additional studies with long-term follow up are needed before it can be widely recommended...

The intestinal microbiota is well-known for a long time, but due to newly recognized functions, clinician's attention has turned to it again in the last decade. About 100 000 billion bacteria are present in the human intestines. The composition of bacteriota living in diverse parts of the intestinal tract is variable according to age, body weight, geological site, and diet as well. Normal bacteriota defend the organism against the penetration of harmful microorganisms, and has many other functions in the gut wall integrity, innate immunity, insulin sensitivity, metabolism, and it is in cross-talk with the brain functions as well...
