Bariatric surgery has proven to be the most effective weight loss strategy in severe obesity. Imaging in the immediate postoperative period of bariatric surgery is not done routinely. However, it is helpful in the assessment of early and late complications, which are estimated to be present in < 1% of patients. In some cases, the imaging interpretation of anatomical outcomes and complications related to these procedures represents a challenge for surgeons and radiologists. The aim of this review is to describe the imagenologic findings after bariatric surgery and focuses on the findings of the most frequent procedures performed in Colombia such as laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic adjustable gastric banding...

INTRODUCTION: Different factors, such as age, gender, preoperative weight but also the patient's motivation, are known to impact outcomes after Roux-en-Y gastric bypass (RYGBP). Weight loss prediction is helpful to define realistic expectations and maintain motivation during follow-up, but also to select good candidates for surgery and limit failures. Therefore, developing a realistic predictive tool appears interesting. PATIENTS/METHODS: A Swiss cohort (n = 444), who underwent RYGBP, was used, with multiple linear regression models, to predict weight loss up to 60 months after surgery considering age, height, gender and weight at baseline...

Metabolic surgery is superior to lifestyle intervention in reducing weight and lowering glycemia and recently suggested as treatment for type 2 diabetes mellitus. Especially Roux-en-Y gastric bypass (RYGB) has been focus for much research, but still the mechanisms of action are only partly elucidated. We suggest that several mechanisms might be mediated by sphingolipids like sphingomyelin. We measured serum sphingomyelin before and up to 2 years after RYGB surgery in 220 patients, divided before surgery in one non-diabetic subgroup and two diabetic subgroups, one of which contained patients obtaining remission of type 2 diabetes after RYGB, while patients in the other still had diabetes after RYGB...

BACKGROUND: Uncut Roux-en-Y gastrojejunostomy (uRYGJ) was developed to prevent slow peristalsis in the Roux limb after Roux-en-Y gastrojejunostomy (RYGJ). This study compared the incidence of Roux stasis syndrome (RSS) and severe gastric food stasis in gastric cancer patients who underwent RYGJ or uRYGJ after laparoscopic curative distal gastrectomy. METHODS: Between January 2006 and June 2012, 319 patients underwent RYGJ or uRYGJ. After covariates were adjusted by propensity score matching, 39 patients in the RYGJ group and 65 patients in the uRYGJ group were included in the final analysis...

BACKGROUND: Chylous ascites is considered to be an intra-abdominal collection of creamy colored fluid with triglyceride content of > 110 mg/dL. Chylous ascites is an uncommon but serious complication of numerous surgical interventions. However, it is a rare complication of LRYGB. An internal hernia limb defect is thought to be the underlying etiology, where the hernia will cause lymphatic vessel engorgement and lymphatic extravasation. CASE PRESENTATION: We report a case of a 29 years old male with a 9 year history of laparoscopic Roux en y gastric bypass (LRGYB), presenting with recurrent abdominal pain for 2 months radiating to the right shoulder...

BACKGROUND: Sleeve gastrectomy (LSG) is now the predominant bariatric surgery performed, yet there is limited long-term data comparing important outcomes between LSG and Roux-en-Y gastric bypass (RYGB). This study compares weight loss and impact on comorbidities of the two procedures. METHODS: We retrospectively evaluated weight, blood pressure, hemoglobin A1c, cholesterol, and medication use for hypertension, diabetes, and hyperlipidemia at 1-4 years post-operatively in 380 patients who underwent RYGB and 334 patients who underwent LSG at the University of Michigan from January 2008 to November 2013...

BACKGROUND: Single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) is a modification of Roux-en-Y duodenal switch (RYDS). Long-term data on this operation is lacking in the literature. We reviewed our mid-term data of this RYDS modification. PURPOSE: To analyze the outcomes with SADI-S at 4 years. METHODS: Data from patients who underwent a primary SADI-S procedure performed by three surgeons at a single institution from June 2013 through February 2018 were retrospectively reviewed...

BACKGROUND AND AIMS: Predictive equations remain the clinical tool of choice to estimate the energy expenditure, however, poor accuracy has been found when applied in patients with severe obesity. The aim of this study was to test the accuracy of the total energy expenditure (TEE) those obtained by predictive equations of resting energy expenditure (REE) times individual estimates of metabolic equivalents (MET), taking as reference the TEE measured by doubly labeled water (DLW), before, six and twelve months after bariatric surgery...

OBJECTIVES: Decreased gut microbial gene richness (MGR) and compositional changes are associated with adverse metabolism in overweight or moderate obesity, but lack characterisation in severe obesity. Bariatric surgery (BS) improves metabolism and inflammation in severe obesity and is associated with gut microbiota modifications. Here, we characterised severe obesity-associated dysbiosis (ie, MGR, microbiota composition and functional characteristics) and assessed whether BS would rescue these changes...

OBJECTIVE: Obesity is associated with a high incidence of obstructive sleep apnoea (OSA). Bariatric surgery is postulated to lead to OSA resolution, but there is inconclusive evidence on its efficacy. We used objective measurements to determine the rate of resolution or improvement of OSA in patients who had bariatric procedures in our unit. RESULTS: Data was analysed on all patients with OSA who underwent bariatric procedures [laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG)] between June 2012 and September 2016 in our unit...

Obesity and physical inactivity are major health problems. Roux-en-Y gastric bypass (RYGB) surgery results in significant weight loss and reduces obesity-related morbidity and mortality. Physical activity lowers the risk of cardiovascular disease and premature death. The aims of this study were to elucidate the effects of RYGB followed by 6 months of supervised physical training on physical capacity. In a randomized controlled trial, 60 participants eligible for RYGB were randomized 6 months post-surgery to either two weekly physical training sessions for 26 weeks (INT) or a control group (CON)...

BACKGROUND: The effectiveness of bariatric surgery among Medicaid beneficiaries, a population with a disproportionately high burden of obesity, remains unclear. We sought to determine if weight loss and regain following bariatric surgery differed in Medicaid patients compared to commercial insurance. SUBJECTS/METHODS: Data from the Longitudinal Assessment of Bariatric Surgery, a ten-site observational cohort of adults undergoing bariatric surgery (2006-2009) were examined for patients who underwent Roux-en-Y Gastric Bypass (RYGB), Laparoscopic Adjustable Band (LAGB), or Sleeve Gastrectomy (SG)...
