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: This study retrospectively reviewed patients who underwent laparoscopic resizing of the gastric pouch (LPR) after weight regain (WR) following gastric bypass procedures. The results showed that LPR had good outcomes in terms of weight loss and improvement of comorbidities, with an acceptable rate of complications and operative time.

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: 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: 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 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.

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: Conversion of OAGB to RYGB as a reparative surgery is an effective procedure with no major weight regain at 2 years of follow-up.

Summary: This study aimed to replicate the methodology used for determining %AWL and proposed a new metric %MAWL, with results showing that using a reference point of 18 instead of 13 produced initial-weight-independent outcomes in Mediterranean patients.

Summary: OAGB/MGB as a revisional procedure after restrictive bariatric procedures shows promising outcomes in reducing BMI, improving T2DM remission rates, and increasing GERD remission/improvement rates, but potential complications such as leakage should be noted.

Summary: The study found that the clinical efficacy of LRYGB in managing obesity over 11 years was better than LSG. However, there were no statistically significant differences in weight loss and regain after 8 years post-surgery, and no significant disparities in surgery-related mortality and severe complications between the two procedures.

Summary: This study compared the short- and medium-term outcomes of SG and RYGB after failure of primary GB. In propensity score matching analysis, SG group had significantly shorter operative time and lower post-operative complications. Weight loss and comorbidities at 2 years follow-up were similar between the two groups, but SG had a significantly lower rate of adverse events.
