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: This study compared the efficacy of RYGB and SG for T2D remission and found that RYGB had a higher chance of achieving remission at 1 year compared to SG, while only showing a significant difference in achieving broad criteria for remission at 5 years. No other differences were found between the two procedures.

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: Morbid obesity is a chronic disease with a rising incidence, and surgical treatment has shown superior outcomes compared to conventional weight loss measures. This study evaluated the long-term weight loss outcomes, comorbidity reduction, and adverse effects of Roux-en-Y Gastric Bypass (RYGB), Biliopancreatic Diversion (BPD), and Sleeve Gastrectomy (SG) at 10 years. RYGB and BPD resulted in significant weight loss, with no observed differences in diabetes resolution and adverse outcomes. Longer follow-up reports are important for comparing the outcomes of different bariatric operations.

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: This study compared the long-term risks of reintervention following sleeve gastrectomy and Roux-en-Y gastric bypass, and found that sleeve gastrectomy was associated with significantly lower risk of reintervention in all categories at the 5-year follow-up. Patients undergoing sleeve gastrectomy had better outcomes in subsequent interventions when compared with those undergoing Roux-en-Y gastric bypass.

Summary: The prevalence of obesity has been increasing rapidly in recent decades, making it one of the most impacting diseases on global health. It is a chronic disease associated with various comorbidities that result in a reduced life expectancy and quality of life. The treatment of obesity requires a multidisciplinary approach by a specialized medical team and can be done through conservative or surgical treatments. Vertical gastrectomy, mixed techniques, and gastric bypass are the most commonly used surgical techniques. The choice of technique should consider the characteristics of each patient and the surgical team's experience.

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: Revisional sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) have better long-term durability compared to primary surgery in terms of revision or conversion.

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: This study reported the experience of 17 patients undergoing RYGBP for chronic leak after LSG. Results showed that surgery should be considered in case of failure of endoscopic treatment, and the RYGBP approach including the leak site offered a low morbidity rate in our experience.

Summary: This study compared the analytical and densitometric changes 2 years after RYGB and SG. The results showed no significant difference in weight loss between the two procedures. However, the RYGB group had a significantly greater increase in PTH values and a greater decrease in bone mineral density compared to the SG group.

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 evaluated a new bariatric procedure, omega loop gastroileal bypass (OLGIBP/SAGI), designed to avoid some drawbacks of the conventional one anastomosis gastric bypass (OAGB). Results showed that OLGIBP and OAGB had similar operative times, hospital lengths of stay, and complication rates. The OLGIBP group had slightly lower rates of bile reflux and total weight loss compared to the OAGB group.

Summary: A systematic review was conducted to evaluate the outcomes of laparoscopic greater curvature plication (LGCP) in the treatment of obesity. The results suggest that LGCP is an acceptable surgical procedure for obesity treatment, especially in settings with limited medical budget. However, existing comparative studies indicate that laparoscopic sleeve gastrectomy (LSG) may be superior in terms of weight loss outcomes.

Summary: The predisposing factors for new-onset orthostatic intolerance after bariatric surgery are still unknown, with a higher proportion of female patients and common comorbidities being hypertension, type 2 diabetes mellitus, and obstructive sleep apnea syndrome. Surgical interventions such as revision, conversion, or reversal were not documented in the studies.

Summary: This systematic review evaluates the safety and efficacy of Roux-en-Y gastric bypass (RYGB) as a revisional bariatric surgical procedure after failed anti-reflux surgery. The results show that RYGB has a good effect in improving patients' weight and reflux condition. However, the risks of perioperative and long-term complications should be minimized, and the surgery should be performed by experienced surgeons in specialized centers for selected patients.
