Current State of Bariatric Surgery - Procedures, Data, and Patient Management

Bariatric surgery comprises a group of operative procedures designed to improve weight-related medical conditions. In the United States, these include vertical sleeve gastrectomy, Roux-en-Y gastric bypass, adjustable gastric banding, and the duodenal switch procedure. Bariatric surgery is the only durable and effective way for most humans to lose a significant amount of weight, and see improvement in obesity-related comorbidities. It can improve quality of life, prevent a number of cancers, and decrease overall mortality.

Obesity is a serious, chronic, treatable, and global disease epidemic. Over 98 million people currently have the disease of obesity, and in a recent New England Journal of Medicine article, Harvard researchers predicted that by 2030, 50% of the population in the United States will have the disease of obesity. Type 2 diabetes (T2D) is significantly associated with obesity. While many people with obesity do not have diabetes, most people with T2D have the disease of obesity. Excess adiposity (body fat storage), which is present in obesity, contributes to many chronic diseases beyond T2D. These include high blood pressure, he...

ConclusionsThis case report highlights the importance to have gastroscopy to observe the proximal small remnant stomach after RYGB in long-term follow-up. Attention must be paid when patients develop symptoms like abdominal pain or excessive weight loss after RYGB. For patients at high risk such as those who have a family history of gastric cancer or presenting abnormal levels of tumor markers should rather undergo Sleeve Gastrectomy plus Jejunojejunal Bypass (SGJB) instead of RYGB.

Conclusions: Bariatric surgery appears to be capable of partially reversing the obesity-related epigenome. The identification of potential epigenetic biomarkers predictive for the success of bariatric surgery may open new doors to personalized therapy for severe obesity. Introduction Obesity is currently a huge healthcare problem, worldwide, and is a risk factor for several diseases such as type 2 diabetes (T2D), cardiovascular disease and cancer (1). As the prevalence of obesity reaches pandemic proportions, this metabolic disease is estimated to become the biggest cause of mortality in the near future (2). In fact,...

Bariatric surgery is the most effective therapy for patients with morbid obesity today [1]. However, the types of operation are still evolving. Sleeve gastrectomy (SG) recently has quickly gained popularity as a primary bariatric surgery worldwide [2,3]. SG plus duodeno-jejunostomy (SG-DJB) was introduced in 2007 as an alternative to Roux-en-Y gastric bypass (RYGB) because the issue of gastric cancer arising from the excluded stomach [4]. SG-DJB can be regarded as a modification of duodenal switch (DS) with short bypass limb and fewer nutritional problems [5].

Background: Women of child-bearing potential generally experience an increase in fertility following bariatric surgery. However, the most commonly performed bariatric operations, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (VSG), may impair absorption of oral contraceptives, potentially rendering them ineffective. Moreover, women desiring to lose weight should avoid contraceptive medications known to cause weight gain. As an alternative, bilateral salpingectomy provides highly reliable contraception and has even been proposed as a strategy to reduce the risk of ovarian, tubal, and peritoneal cancers.

CONCLUSION: Bariatric surgery is associated with decreased risk of hormone-related cancers, whereas gastric bypass might increase the risk of colorectal cancer. PMID: 30003539 [PubMed - as supplied by publisher]

Roux-en-Y gastric bypass (RYGB) improves comorbidities such as diabetes and hypertension and lowers the risk of obesity-related cancers. To better understand the physiologic and genetic influences of bariatric surgery, a reliable murine model is needed that can be extended to genetically engineered mice. Given the complexity of these procedures, few researchers have successfully implemented these techniques beyond larger rodent models. The purpose of our study was to develop a technically feasible and reproducible murine model for RYGB and sleeve gastrectomy (SG).
