ARTICLE HIGHLIGHTS
Research background
Magnetic compression anastomosis (MCA) has been reported in gastrointestinal anastomosis and small intestine anastomosis, however, there is no relevant report on the application of MCA in esophagojejunostomy and jejunojejunostomy after total gastrectomy.
Research motivation
To investigate the feasibility of total magnetic anastomosis reconstruction of digestive tract after total gastrectomy.
Research objectives
To design the magnet anastomosis rings for reconstruction of digestive tract magnamosis after total gastrectomy and investigate its feasibility.
Research methods
Sixteen beagle dogs were randomly assigned to the MCA group and the manual suture group. The operation time, postoperative complication and anastomosis specimens were examined between the two groups.
Research results
The results showed that the anastomosis time of MCA group was significantly shorter than that of manual suture anastomosis group. The study group showed a greater smoothness of the anastomosis than that of the control group.
Research conclusions
MCA is safe and feasible for digestive-tract anastomosis reconstruction after total gastrectomy.
Research perspectives
Animal experiments show that MCA has advantages for digestive-tract anastomosis reconstruction after total gastrectomy, which can be applied in clinic after further optimization of magnet design.
