The EndoBarrier has a weak point caused by a Teflon membrane, which completely inhibits the movement of water and food. We developed a new type of gastro jejunal inner lumen bypass device (GJB) using an artificial net that has a hole instead of a membrane. We inserted a net in the gastric antrum-duodenum–jejunum via open laparotomy. The growth of pigs with long nets was suppressed compared with the sham operation. However, there were no differences in blood biochemistry or anatomical findings at autopsy between the groups. As a result, GJB can control the growth of pigs without requiring dietary restriction.
