Influence of glucometric 'dynamical' variables on duodenal-jejunal bypass liner (DJBL) anthropometric and metabolic outcomes

Efficacy and safety of duodenal-jejunal bypass liner for obesity and type 2 diabetes: A systematic review and meta-analysis

This study aimed to evaluate the efficacy and safety of duodenal-jejunal bypass liner (DJBL) for obesity and type 2 diabetes mellitus. A comprehensive search of electronic databases was conducted up to September 15, 2022. Thirty studies involving 1751 patients were included. At 12 months post-implantation, the reduction in body mass index (BMI) was 4.8 kg/m2 (95% CI 4.1, 5.5), with an excess weight loss of 41.3% (95% CI 33.4%,49.2%) and a total weight loss of 13.1% (95% CI 10.1%, 16.0%). Significant decrease was observed in HbA1c and fasting glucose, with a standardized mean difference of - 0.72 (95% CI - 0.95, - 0.48) and - 0.62 (95% CI - 0.82, - 0.42), respectively. However, these improvements in weight loss and glycemic control were only partially sustained after explantation. In situ, DJBL significantly improves blood pressure and lipid levels. The pooled early removal rate was 19%, and the incidence of severe adverse events was 17%, including device migration (6%), gastrointestinal hemorrhage (4%), device obstruction (4%), and hepatic abscess (2%). DJBL offers significant improvement in weight loss and glycemic control, as well as cardiovascular parameters while in situ. Further studies are warranted to better understand the long-term efficacy and safety of DJBL. The benefits of DJBL need to be carefully weighed against the risks in clinical decision-making.

The Role of duodenal jejunal bypass liner in obesity treatment

<abstract> <p>Endoscopic bariatric procedures including Duedenal Jejunal Bypass Liner (DJBL) have become widespread in obesity treatment in recent years. The aim of this systematic review was to assess the role of DJBL in obesity treatment. A comprehensive search of several databases, including Cochrane Library, PubMed, and Web of Science was conducted to December 2020. Twenty-four clinical studies were assessed. According to the results, it is clear that DJBL provides effective weight reduction at 6–12 months and significant improvements in parameters associated with metabolic syndrome and cardiovascular disease. This technique also has potential to reduce comedications in patients with obesity and type 2 diabetes. Although these positive effects of DJBL are clear, its effect on liver, pancreatic functions, and inflammation markers are not clear yet. In addition, the overall and serious complication (gastrointestinal bleeds, pancreatitis, hepatic abscess, obstruction of the sleeve, biliary colic without cholecystitis and cholangitis) rate causing from the DJBL is very high. DJBL has not been approved by the Food and Drug Administration due to the frequency and severity of complications it causes. While it is certain that DJBL has significant effects on obesity and obesity related comorbidities, the safety aspect needs to be improved.</p> </abstract>
