Further Development of Magnetic Compression for Gastrojejunostomy in Rabbits

The creation of functioning gastrojejunostomy following magnetic compression

“…Anesthesia administered as intravenous pentobarbital (30 mg/kg) was followed by fixation on the operating table in the supine position with a straight neck. In the present experiment, the magnets and half-capsules were sequentially introduced into the stomach along a ferromagnetic guidewire, as described in the previous experiment [9]. Then, the jejunal magnet was squeezed into the jejunum through the pylorus.…”

“…Following mechanical device release after healing, however, the contraction and stenosis of the stoma are the pivotal points, upon which the utility of the devices rests [5][6][7][8]. In the prior study published from our group, anastomotic contraction occurred immediately after the removal of compression magnets, regardless of whether rectangle-or cylinder-shaped magnets were used [9]. The character of contraction recovers the rhythm of dietary excretion after the reconstruction of the alimentary tract and, to some extent, can be effectively utilized to prevent digestive reflux.…”
