Summary: Background: The rates of secondary bariatric surgery have increased, with sleeve gastrectomy to gastric bypass conversion being the most common. This study evaluates the outcomes of this conversion compared to primary Roux-en-Y gastric bypass (RYGB) surgery using MBSAQIP data. Methods: The study analyzed the data of patients who underwent sleeve gastrectomy to RYGB conversion and primary laparoscopic RYGB, matching them based on preoperative characteristics. Results: The analysis showed that the conversion from sleeve gastrectomy to RYGB was associated with higher readmissions, interventions, conversion to open surgery, longer hospital stay, and longer operative time compared to primary RYGB. However, there were no significant differences in mortality or rates of bariatric complications. Conclusion: The study concludes that conversion from sleeve gastrectomy to RYGB is a safe and feasible procedure with reasonable outcomes compared to primary RYGB.

Summary: The study found that patients who underwent laparoscopic RYGB by surgeons with lower volumes had slightly increased risks of complications and readmissions at 30 days and within 1 year, but overall, surgeon RYGB volume did not have a significant impact on patient outcomes. Patients can safely pursue RYGB in this early phase of the sleeve gastrectomy era.

Summary: This study evaluated the incidence of marginal ulcers (MUs) after primary and secondary Roux-en-Y Gastric Bypass (RYGB). The results showed that patients who underwent conversion of Sleeve Gastrectomy to RYGB had a higher incidence of MUs compared to those who had primary RYGB or Gastric Banding to RYGB. Furthermore, the time to MU development was significantly shorter in patients who underwent conversion surgery.

Summary: The decision to perform LRYGB is primarily driven by obesity-associated comorbidities and higher BMI, whereas LSG is more likely to be performed in higher risk patients.

Summary: The study aimed to determine the weight-loss outcomes of patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) after laparoscopic sleeve gastrectomy (LSG) and whether outcomes differed according to indications for conversion. The study found that patients who underwent LRYGB after previous LSG had a consistent weight-loss outcome regardless of the reason for conversion.

Summary: The objective of this study was to characterize the patients who underwent conversion from laparoscopic sleeve gastrectomy (LSG) to Roux-En-Y Gastric Bypass (RYGB) and to better understand pre-operative predictors of gastroesophageal reflux disease (GERD) and revision. The study found that the majority of patients who underwent the conversion surgery experienced significant improvements in GERD symptoms and outcomes.

Summary: This study investigated the effects of sleeve gastrectomy and Roux-en-Y gastric bypass on gastrointestinal motility, pH, and bile acid concentration. The findings showed that both surgeries increased pouch emptying and gastric emptying, and also led to higher pH levels and bile acid concentrations in the intestines. These results highlight the significant impact of these surgeries on gastrointestinal physiology.

Summary: The study found that both SG and RYGBP have significant effects on zinc absorption, which are not compensated for after 24 months post-surgery. Although the reduction in zinc absorption was similar in both types of surgeries, plasma zinc was more affected in RYGBP than SG.

Summary: This study investigated the microbial, metabolomic, and inflammatory changes following bariatric surgery. The results showed significant microbial changes after Roux-en-Y gastric bypass, while sleeve gastrectomy had minimal impact on microbial diversity and genera. Romboutsia genera were found to be associated with weight loss and insulin resistance. These findings provide comprehensive insights into the metabolic effects of bariatric surgery.

Summary: This study aimed to compare the safety outcomes of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). The study found that compared to RYGB, SG was associated with lower rates of hospital readmissions, emergency room visits, and gastrointestinal bleeding, but had a higher risk of revisional surgery.

Summary: In patients with BMI >= 60 kg/m(2), LRYGB resulted in better weight loss and medication discontinuation one year post-surgery compared to LSG, but with an increase in perioperative complications and resource utilization.

Summary: This study compared weight loss outcomes between Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in young adults and found that RYGB resulted in greater weight loss in the short- and midterm, particularly in females.

Summary: This study compared the extent of weight recurrence between patients who received Sleeve Gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) after adequate weight loss at 1-year follow-up. The results showed that patients undergoing SG had a higher likelihood of weight recurrence up to 5 years and were less likely to achieve remission of comorbidities such as type 2 diabetes, hypertension, dyslipidemia, gastroesophageal reflux, and obstructive sleep apnea syndrome.

Summary: This study aimed to assess the impact of Roux-en-Y gastric bypass and sleeve gastrectomy on patients with NAFLD. The findings suggest that sleeve gastrectomy leads to a significant improvement in liver function, while preoperative factors such as T2DM, weight, and male sex may contribute to postoperative deterioration of liver function.

Summary: Conversion from sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB) is often necessary due to gastroesophageal reflux disease (GERD) or weight regain. Limited evidence exists regarding the safety and indications of SG-RYGB conversion. A retrospective analysis of the MBSAQIP database was conducted to compare the outcomes of primary RYGB (P-RYGB) and SG-RYGB. The study found that SG-RYGB had higher rates of serious complications, including anastomotic leak, bleeding, and reoperation, but no significant increase in mortality compared to P-RYGB.
