New Anchoring Mechanism and Design of an Endoluminal Duodeno-Jejunal Bypass Liner for Treatment of Obesity: a Pilot Animal Trial

Obes Surg. 2019 Sep;29(9):3081-3085. doi: 10.1007/s11695-019-03945-x.

Abstract

Objective: Complications of bleeding, liver abscess and movement have been associated with previous duodeno-jejunal bypass liner (DJBL) applications in the past. A new anchoring system and design of a DJBL is presented as a pilot study.

Method: A newly designed DJBL device was inserted in 2 pigs and observed over 2 months.

Results: The newly designed device was anchored and monitored for 1 month in 1 of 2 pigs, the other being passed early. Effectiveness and safety have been shown.

Conclusion: The results of this pilot study warrant further investigation of the modified DJBL setup, which may help solve standing issues associated with the clinical use of a DJB liner.

Keywords: Anchoring system; DJB liner; Pilot study.
