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 study found that weight loss following RYGB may increase IL-22 serum levels, indicating that weight loss directly contributes to immune modulation following bypass.

Summary: A systematic review and meta-analysis were conducted to evaluate various revisional techniques for addressing weight regain and inadequate weight loss after Roux-en-Y gastric bypass. The results showed that endoscopic procedures resulted in short-term weight loss, while surgical revision techniques were more successful in achieving long-term weight loss, albeit with higher complication rates.

Summary: Complications like leaks after one-anastomosis gastric bypass (OAGB) should be managed properly, but there is limited data and no guidelines for leak management. A systematic review and meta-analysis of 46 studies involving 44,318 OAGB patients found a 1% prevalence of leaks. Surgical strategies varied, but about 62.1% of patients with leaks required additional surgery. The most common procedures for leak management were peritoneal washout and drainage, followed by conversion to Roux-en-Y gastric bypass. The mortality rate related to leaks was 1.95%.

Summary: This study evaluated the outcomes of converting sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB) for weight loss and identified predictors of below-average weight loss. The results showed that weight loss outcomes were lower at 1 year (41.5%) and 2 years (30.8%) after SG to RYGB conversion compared to primary RYGB. The interval to conversion <2 years and preconversion BMI >40 were predictors of below-average 1-year weight loss after conversion.

Summary: In this study, SG+JJB resulted in higher weight loss than SG and comparable weight loss to RYGB at the 3-year follow-up. The diabetes remission rate of SG+JJB was similar to SG or RYGB. However, SG+JJB increased the risk of malodorous flatus compared to SG and de novo GERD symptoms compared to RYGB.

Summary: Pouch resizing after Roux-en-Y gastric bypass (RYGB) results in a failure rate of 47% at the 10-year follow-up, while the resolution of comorbidities is maintained over time despite significant weight regain.

Summary: For patients with a BMI greater than 50, One-Anastomosis Gastric Bypass (OAGB) may be more effective than Sleeve Gastrectomy (SG) for treating obesity. A systematic review and meta-analysis of nine retrospective studies involving a total of 2332 participants showed that OAGB achieved significantly higher percentages of excess weight loss and total weight loss compared to SG in patients with a BMI greater than 50. However, there were no significant differences in operative time and length of hospital stay between the two procedures. Additionally, there were no major differences in perioperative outcomes, complications, and diabetes remission between OAGB and SG.

Summary: This study evaluated the impact of the severity of dumping syndrome (DS) on weight loss outcomes after Roux-en-Y gastric bypass (RYGB) in patients with class III obesity. A total of 207 patients were divided into group A with mild-to-moderate DS and group B with severe DS. The severity of DS was assessed using the dumping symptom rating scale (DSRS) and its correlation with weight loss outcomes was examined one year after RYGB. The results showed that there were insignificant relationships between the presence and severity of DS after RYGB and adequate postoperative weight loss.

Summary: Among patients with severe obesity undergoing SG and RYGB, significantly more weight loss was observed at 5 years compared to nonsurgical patients. Weight regain was common after surgery, but regain to within 5% of baseline was rare.

Summary: The narrative review discusses the potential optimization of outcomes in laparoscopic Roux-en-Y gastric bypass surgery by modifying the length of bypassed small intestine based on total small intestinal length. Due to the heterogeneity of included studies, the authors emphasize the importance of carefully selecting the excluded small intestine length for each individual patient to achieve efficient metabolic outcomes.

Summary: A longer BPL (biliopancreatic limb) is associated with more %EWL and %TWL 2 years after RYGB. However, it is accompanied by an increase in diarrhea and steatorrhea. Future studies should focus on tailoring BPL and AL lengths for optimal outcomes in morbidly obese patients.

Summary: This study compared the effect of banded and non-banded Roux-en-Y gastric bypass (RYGB) on weight loss over a 5-year follow-up period. The results showed that patients who underwent banded RYGB had a lower risk of insufficient weight loss compared to those who underwent non-banded RYGB. There were no differences in cardiometabolic outcomes between the two groups. Further research is needed to understand the effects of eating behavior restriction and neuroendocrine responses after RYGB.

Summary: This study prospectively reports weight loss and comorbidity resolution in patients undergoing LRYGB with at least 15-year follow-up. The results show durable weight loss and long-term resolution of obesity-related comorbidities after LRYGB for at least 15 years.

Summary: This study aimed to compare the use of opioids in patients with obesity who underwent bariatric surgery versus those who underwent intensive lifestyle modification. The results showed that patients who underwent bariatric surgery had a higher proportion of opioid users and a larger total opioid dose, especially in those who received additional surgery during follow-up.
