Laparoscopic Roux-en-Y gastric bypass is an effective surgical procedure to manage obesity and associated comorbidities. Despite this, some patients experience suboptimal weight loss or weight regain. Several revisional options are available following gastric bypass. Distalization, by increasing the biliopancreatic limb and decreasing the common channel, has been previously shown to improve weight loss with low perioperative morbidity. The impact on weight and nutritional deficiencies is associated with lengths of the different intestinal limbs...

PURPOSE: Fat-free mass (FFM) loss is a concerning aspect of bariatric surgery, but little is known about its time-course and factors related with excessive FFM loss. This study examined (i) the progress of FFM loss up to 3 years post-bariatric surgery and (ii) the prevalence and determinants of excessive FFM loss. MATERIALS AND METHODS: A total of 3596 patients (20% males, 43.5 ± 11.1 years old, BMI = 44.2 ± 5.5 kg/m2 ) underwent sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) surgery...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is among the most performed bariatric surgery techniques. One known complication of RYGB surgery is food intolerance, which may limit the intake of protein. OBJECTIVE: To investigate the relationship of food intolerance after RYGB surgery with masticatory efficiency, chewing time and cycles, and consumption of protein and red meat. METHODS: A case-control study in subjects with and without food intolerance (regurgitation and/or vomiting more than once a week) aged over 18 years old who had undergone RYGB more than 2 years prior, with an absence of no more than 2 dental units and normal oral motor system evaluation...

BACKGROUND: Hypothyroidism is frequently found to be associated with morbid obesity. Effect of bariatric surgery on type 2 diabetes, hypertension, and sleep apnea has been studied extensively but there is a dearth of literature on its impact on thyroid function. We had published our experience of laparoscopic sleeve gastrectomy and its effect on hypothyroidism in morbidly obese patients previously. In this study, we have tried to evaluate the impact of bariatric surgery on the whole cohort of hypothyroid patients and compare the effect of various bariatric procedures on thyroid hormone replacement dose...

OBJECTIVE: Patients undergoing bariatric surgery present long-term metabolic improvements and reduced type 2 diabetes risk, despite long-term weight regain. We hypothesized that part of these protective effects could be linked to altered gene expression in white adipose tissue (WAT). METHODS: Transcriptomic profiling by gene microarray was performed in abdominal subcutaneous WAT from women before (n = 50) and two (n = 49) and five (n = 38) years after Roux-en-Y gastric bypass (RYGB) surgery as well as in 28 age-matched nonoperated women...

PURPOSE: One-anastomosis gastric bypass (OAGB) has raised concerns about nutritional complications possibly attributed to the biliopancreatic limb (BPL) length. We aimed to assess the results of a conservative approach of OAGB compared with the original OAGB and Roux-en-Y gastric bypass (RYGB) in a 1-year follow-up study. MATERIALS AND METHODS: This retrospective study was conducted based on prospectively maintained data in a cohort of patients who underwent either RYGB with a Roux limb of a 150 cm and a BPL of 50 cm (n = 145), OAGB with a 200-cm BPL (n = 272), or OAGB with a 160-cm BPL (n = 383), from March 2013 to 2017 at three university hospitals by a single surgical team...

PURPOSE: Morbid obesity is associated with reduced patients' perception quality of life (QoL). The health benefit of Laparoscopic Roux-en-Y gastric bypass (LRYGB) is well established with long-term weight control and QoL improvement. The laparoscopic functional gastric bypass with fundectomy and gastric remnant exploration (LRYGBfse) has been described with promising results in terms of weight loss and comorbid resolution. The purpose of this study was to investigate its contribution on patients' QoL at 5-year follow-up...

PURPOSE OF REVIEW: The aim of the article is to review studies on bone health and oxalate metabolism/therapeutics in the obese rodent model of Roux-en-Y gastric bypass (RYGB) and examine pathways to decrease procedural morbidity. RECENT FINDINGS: Compared with controls, RYGB rodents have up to 40-fold more fat in their stool (steatorrhea) which positively correlates to increased urinary oxalate. These unabsorbed intestinal fatty acids bind calcium and prevent gut calcium oxalate formation, increasing soluble luminal oxalate availability and absorption (enteric hyperoxaluria)...

BACKGROUND/AIM: Soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and amyloid-β(1-40) (Aβ40) emerged as markers of cardiovascular risk because of their actions in the endothelium and their role in atherosclerotic progression. The aim of this study was to analyze the association of these two factors with the decrease in carotid intima-media thickness (cIMT) after bariatric surgery in obese women. METHODS: We studied 60 severely obese women, of whom 20 were submitted to laparoscopic Roux-en-Y gastric bypass (RYGB), 20 to sleeve gastrectomy (SG), and 20 to lifestyle modification therapy...

BACKGROUND: Bariatric surgical procedures have recognized benefits for morbidly obese patients. Unfortunately, staple line leaks remain a profound complication after these procedures. Currently available intraoperative surveillance modalities have multiple drawbacks, such as requiring an available upper endoscope and experienced endoscopist. Additionally, increased procedure time and resources are needed to perform intraoperative endoscopy and maintain equipment. METHODS: This is a retrospective cohort study of all bariatric patients undergoing Roux-en-Y gastric bypass or sleeve gastrectomy procedures performed by one attending surgeon at a tertiary care facility designated as a bariatric surgical center of excellence...

BACKGROUND/AIM: Obesity is associated with increased incidence of gastroesophageal reflux disease (GERD), and it has been suggested that GERD symptoms may be improved by weight reduction. However, various patterns of bariatric surgery may affect symptoms of GERD due to the changed anatomy of stomach and esophagus. The aim of this systematic review and meta-analysis is to analyze the effect of bariatric surgery on GERD. MATERIALS AND METHODS: A systematic literature search was performed using PubMed, EMBASE, and the Cochrane Library from January 2005 to January 2019, combining the words obesity, gastroesophageal reflux with different types of bariatric surgery and weight loss...

Morbid obesity afflicts one third of the population in the United States and decreases life expectancy by 5-20 years. Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been an established operation for the treatment of morbid obesity for nearly three decades. There are several different techniques for performing a LRYGB. We describe our circular stapled gastrojejunostomy technique and our preoperative and postoperative management of patients.
