BACKGROUND: Roux-en-Y gastric bypass (RYGB) can be reversed into normal anatomy (NA) or into sleeve gastrectomy (NASG) to address undesired side effects. Concomitant hiatal hernia repair (HHR) may be required. Before reversal, some patients benefit from placement of a gastrostomy, mostly to predict the result of recreating the native anatomy. METHODS: Retrospective study on mid-term effects of RYGB reversal to NA and NASG, including clinical and weight evolution, surgical complications, and incidence of gastro-esophageal reflux (GERD)...

BACKGROUND: Bariatric surgery is an effective therapy for morbid obesity but may reduce calcium absorption and significantly decrease the bone mineral density. This study examined the prevalence of secondary hyperparathyroidism (SHPT) in obese subjects during follow-up after different bariatric surgeries. We investigated predictors of SHPT. METHODS: We enrolled 1470 obese subjects undergoing bariatric/metabolic surgery with at least 1-year follow-up, including 322 patients undergoing Roux-en-Y gastric bypass (RYGB), 695 undergoing single anastomosis (mini-) gastric bypass (SAGB), 93 undergoing laparoscopic adjustable gastric banding (LAGB), and 360 undergoing sleeve gastrectomy (SG)...

BACKGROUND: The volume of the postoperative gastric remnant is a key factor in excess weight loss (EWL) after sleeve gastrectomy (SG). Traditional methods to estimate gastric volume (GV) after bariatric procedures are often inaccurate; usually conventional biplanar contrast studies are used. METHODS: Thirty patients who underwent SG were followed prospectively and evaluated at 6 months after the surgical procedure, performing 3D CT reconstruction and gastric volumetry, to establish its relationship with EWL...

BACKGROUND: Laparoscopic gastric greater curvature plication (LGGCP) is a restrictive bariatric procedure without gastrectomy. However, limited literature on effectiveness of gastric plication exists. OBJECTIVES: We assessed LGGCP's efficacy, effects on associated comorbidities, safety and the rate of complications, and patient satisfaction with LGGCP's outcomes among morbidly obese patients. METHOD: Analysis of retrospectively data collected from medical records of 26 patients who had undergone LGGCP at Hamad General Hospital, Qatar, during 2011-2012...

Management of early sleeve gastrectomy leak remains challenging. The recommended approach is endoscopic stenting and abdominal drainage. Conversion to a Roux-en-Y gastric bypass (RYGB) is a common procedure used for late fistulas with distal obstruction. Here, we have presented three cases of early staple line leaks treated by conversion to RYGB. These patients had uncontrolled abdominal infections despite intensive medical treatments, and surgery was elected for abdominal drainage as well as to control the source of sepsis...

BACKGROUND: Bariatric surgery remains the most effective treatment for reducing adiposity and eliminating type 2 diabetes; however, the mechanism(s) responsible have remained elusive. Peroxisome proliferator-activated receptors (PPAR) encompass a family of nuclear hormone receptors that upon activation exert control of lipid metabolism, glucose regulation and inflammation. Their role in adipose tissue following bariatric surgery remains undefined. MATERIALS AND METHODS: Subcutaneous adipose tissue biopsies and serum were obtained and evaluated from time of surgery and on postoperative day 7 in patients randomized to Roux-en-Y gastric bypass (n=13) or matched caloric restriction (n=14), as well as patients undergoing vertical sleeve gastrectomy (n=33)...

BACKGROUND: Sleeve gastrectomy (SG) is gaining popularity and has become the procedure of choice for many bariatric surgeons. Long-term weight loss failure is not uncommon. The preferred revisional procedure for these patients is still under debate. OBJECTIVE: The objective of this study was to assess the safety and efficacy of laparoscopic gastric bypass as a revisional surgery for sleeve gastrectomy patients with weight loss failure. SETTING: The study was done at a bariatric surgery center in a university hospital...

REVIEW
Aneta Stefanidis, Brian J Oldfield
Obesity has reached epidemic proportions and to date, bariatric surgery remains the only effective treatment for morbid obesity in terms of its capacity to achieve durable weight loss. Bariatric surgery procedures, including Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB) and sleeve gastrectomy (SG) have been the primary procedures conducted over the past decade, with SG increasing in popularity over the past five years at the expense of both RYGB and AGB. Although these procedures were initially proposed to function via restrictive or malabsorptive mechanisms, it is now clear that profound physiological changes underlie the metabolic improvements in patients who undergo bariatric surgery...

Severe obesity (body mass index>120% of BMI IOTF-30 cut off) and morbid obesity (BMI>140% of BMI IOTF-30 cut off) affect 5 to 10% of obese adolescents in France. Organic complications can be found in about 50% of these patients, and depressive symptoms in one-third of them. Finally, over 70% will suffer from adult morbid obesity associated with a marked increase in morbidity and mortality. However, the reversion of obesity strongly decreases, and may even cancels, these risks. In controlled randomized studies, lifestyle interventions have limited effectiveness on BMI in children (and none in adolescents)...

BACKGROUND: Paraesophageal hernia (PEH) is a common condition that bariatric surgeons encounter. Expert opinion is split on whether bariatric surgery and PEH repair should be completed concurrently or sequentially. We hypothesized that concurrent bariatric surgery and PEH repair is safe. OBJECTIVES: We examined 30-day outcomes after concomitant PEH repair and bariatric surgery. SETTING: National database, United States. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database (2011-2014), we identified patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) with or without PEH repair...

BACKGROUND: Studies have shown conflicting effects of resident involvement on outcomes after laparoscopic bariatric surgery. Resident involvement may be a proxy for a teaching environment in which multiple factors affect patient outcomes. However, no study has examined outcomes of laparoscopic bariatric surgery based on hospital teaching status. OBJECTIVE: To compare outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) between teaching hospitals (THs) and nonteaching hospitals (NTHs)...

We present a rare case of a big oesophageal liposarcoma causing dysphagia and weight loss in a 75-year-old patient. Endoscopically, a pedunculated lesion with subtotal obstruction of the oesophageal lumen had been detected and thoracoabdominal oesophageal resection with gastric sleeve reconstruction was performed. Surprisingly, a liposarcoma of the oesophagus was revealed on histopathological analysis, showing MDM2 overexpression. Oncological follow-up has been uneventful and the patient remains in good clinical shape at 15 months after surgery...

BACKGROUND: Bariatric surgery is an effective treatment for obesity causing changes in energy expenditure. Brown adipose tissue (BAT) is an energy-related organ, and the potential effects of bariatric surgery are yet to be investigated. We aimed to study the effects of different bariatric surgeries on growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis, brown adipocyte differentiation, and energy metabolism in obese mice and explore the underlying mechanisms. METHODS: Mice were fed a high-fat diet for 12 weeks and subjected to different bariatric procedures: adjustable gastric band (AGB), sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and sham operation (SO)...

BACKGROUND: Weight regain (WR) and symptoms of post-bariatric surgery hypoglycemia (PBSH) are metabolic complications observed in a subset of postbariatric patients. Whether hypoglycemic symptoms are an important driver of increased caloric intake and WR after bariatric surgery is unknown. OBJECTIVE: This study aims to determine whether patients with PBSH symptoms have greater odds for WR. SETTING: Tertiary academic hospital. METHODS: Patients who underwent Roux-en-Y gastric bypass or sleeve gastrectomy at our tertiary academic hospital from August 2008 to August 2012 were mailed a survey, from which weight trajectory and PBSH symptoms were assessed...

OBJECTIVE: Although the laparoscopic sleeve gastrectomy (SG) is increasingly performed for morbid obesity, gastric bypass is still considered by many to be the gold standard procedure for obese diabetic patients. The aim of this study was to assess the long-term results of SG in morbidly obese patients with type 2 diabetes. METHODS: Diabetic patients who underwent SG at a single center between 2009 and 2011 were included. Outcomes assessed included postoperative complications, weight loss, and resolution or improvement in co-morbidities with an emphasis on diabetes, including glycated hemoglobin (HbA1C) and medication status...
