Multicenter Study Comparative StudySingle-stage conversions from failed gastric band to sleeve gastrectomy versus Roux-en-Y gastric bypass: results from the United Kingdom National Bariatric Surgical Registry.
For patients in whom laparoscopic adjustable gastric band has failed, conversion to Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy are both options for further surgical treatment. There are limited data comparing these 2 procedures. The National Bariatric Surgery Registry is a comprehensive United Kingdom-wide database of bariatric procedures, in which preoperative demographic characteristics and clinical outcomes are prospectively recorded. ⋯ Conversion from band to sleeve or bypass give comparable good early excess weight loss; however, conversion to sleeve is associated with a better perioperative safety profile.

Comparative Study Clinical TrialEffect of laparoscopic Roux-en-Y gastric bypass versus laparoscopic sleeve gastrectomy on fasting gastrointestinal and pancreatic peptide hormones: A prospective nonrandomized trial.
Changes in gastrointestinal and pancreatic hormones may play a role in promoting long-term weight reduction and improved glucose metabolism after sleeve gastrectomy and Roux-en-Y gastric bypass. However, few studies have examined the metabolic and endocrine effects of these procedures in Mainland China. ⋯ LSG and LRYGB resulted in significant and distinct changes in multiple gastrointestinal and pancreatic peptide hormones that are important regulators of obesity and metabolic health.

Comparative Study Observational StudyImpact of Roux-en-Y gastric bypass and sleeve gastrectomy on fetal growth and relationship with maternal nutritional status.
There is a lack of evidence on whether sleeve gastrectomy (SG), which induces fewer nutritional deficiencies than Roux-en-Y gastric bypass (RYGB), also affects fetal growth (FG). ⋯ FG restriction occurs after both SG and RYGB. FG after bariatric surgery is positively associated with protein supply and negatively correlated with maternal iron status.

Gastric band conversion to Roux-en-Y gastric bypass shows greater weight loss than conversion to sleeve gastrectomy: 5-year outcomes.
Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) are often used as revisional surgeries for a failed laparoscopic adjustable gastric band (LAGB). There is debate over which procedure provides better long-term weight loss. ⋯ Weight loss is significantly greater for patients undergoing LAGB conversion to RYGB than LAGB to LSG. However, those undergoing LAGB conversion to RYGB had higher rates of reoperation and readmission. Patients looking for the most effective weight loss surgery after failed LAGB should be advised to have RYGB performed, while also understanding the increased risks of the procedure.

Comparative StudyHistologic improvement of NAFLD in patients with obesity after bariatric surgery based on standardized NAS (NAFLD activity score).
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder in industrialized countries. Nonalcoholic steatohepatitis is the fastest growing cause for liver failure. Bariatric surgery represents a treatment option for NAFLD with an established effect on liver histology. ⋯ Bariatric surgery significantly improves NAFLD.
