Based upon experiments on animals, an anastomotic apparatus, consisting of two magnetic rings of polymer bonded, rare earth @entity1953 magnets embedded in @entity2635 , was developed. There are three types of polyester device with diameters of 25, 28, and 30 millimeters, respectively. The force between the magnets varied between 2.5 Newtons at 4 centimer separation and 11.8 Newtons at union. For the low @entity14 , a magnet holder, connecting rod and spherical cap were developed. The aim of the technique is a quick restoration of the underbroken submucosal intestinal cylinder by optimal circular apposition of the submucosal layer. The working mechanism is based upon progressive compression, leading to @entity39 of the intermediate mucosal and submucosal layers by increasing the magnetic force while intestinal healing takes place. After seven to 12 days, the magnets cut through the disappear from the anastomotic region by intestinal peristalsis. From the initial series of 21 @entity1 , 11 resections of the sigmoid colon and nine low anterior resections were performed. Dehiscence of the suture line was noted in two instances. One @entity1 required reoperation. The other @entity1 had a small area of dehiscence at the suture line after evacuation of an infected @entity1410 with a further uncomplicated course. One @entity1 died on the third postoperative day of recurrent @entity583 . In the other 18 @entity1 , primary intestinal healing was demonstrated roentgenologically and sigmoidoscopically.
