摘      要：BACKGROUND Although previous studies have confirmed the feasibility of magnetic compression anastomosis(MCA),there is still a risk of long-term anastomotic *** traditional MCA devices,a large device is associated with great pressure,and eventually increased *** To develop a novel MCA device to simultaneously meet the requirements of pressure and *** Traditional nummular MCA devices of all possible sizes were used to conduct ileac anastomosis in *** mean(±SD)circumference of the ileum was 13.34±0.12 *** on short-and long-term follow-up results,we determined the appropriate pressure range and minimum ***,we introduced a novel“fedora-typeMCA device,which entailed the use of a nummular magnet with a larger sheet *** With traditional MCA devices,the anastomoses experienced stenosis and even closure during the long-term follow-up when the anastomat was smaller thanΦ5 ***,the risk of leakage increased when it was larger thanΦ4 *** comparison of the different designs,it was found that the“fedora-typeMCA device should be composed of aΦ4-mm nummular magnet with aΦ6-mm sheet *** The diameter of the MCA device should be greater than 120%of the enteric *** novel“fedora-typeMCA device controls the pressure and optimizes the size.
