Laubner K, et al. - Using German DJBL registry, authors investigated the efficacy and safety of the duodenal-jejunal bypass liner (DJBL) in comparison to lifestyle changes and antidiabetic drugs in obese patients with type 2 diabetes mellitus. Results displayed that the mean treatment time with the DJBL was 47.5 ± 12.2 weeks, mean BMI reduction was 5.0 kg/m² and mean HbA1c reduction was 1.3%. Evidence was yielded regarding a putative positive risk/benefit ratio for treatment of obese patients with type 2 diabetes mellitus with the DJBL as an alternative treatment option for this patient cohort.
