Abstract
Background
The duodenal-jejunal bypass liner (DJBL) is an endoscopic device designed to induce weight loss and improve glycemic control. The liner is licensed for a maximum implant duration of 12 months. It might be hypothesized that extension of the dwelling time results in added value. The goals of our study were to determine weight change, change in glycemic control, and safety in patients with an intended 24 months of DJBL dwelling time.
Methods
Patients were initially selected for a 12-month implantation period. When no physical complaints or adverse events (AEs) occurred, motivated patients who responded well were selected for extension of dwelling time to 24 months. Patients underwent a control endoscopy 12 months after implantation and visited the out-patient clinic every 3 months up to explantation. Patients agreed to remove the DJBL when complaints or AEs occurred that could not be treated conservatively.
Results
Implantation was extended in 44 patients, and 24 (55%) patients completed the full 24 months. Twenty patients required early removal due to AEs. During dwelling time, body weight decreased significantly (15.9 kg; TBWL 14.6%). HbA1c decreased non-significantly (4.9 mmol/mol). The number of insulin users and daily dose of insulin both decreased significantly. At 24 months after removal, glycemic control had worsened, while body weight was still significantly lower compared to baseline. In total, 68% of the patients experienced at least one AE. Two patients developed a hepatic abscess.
Conclusions
DJBL treatment results in significant weight loss and improves glycemic control during implantation. The largest beneficial effects occur during the first 9–12 months after implantation. Extension of dwelling time to 24 months results only in stabilization of body weight and glycemic control. After explantation, weight improvements are maintained, but glycemic control worsens. As the cumulative risk of AEs increases with time, a maximal dwelling time of 12 months is advisable.
