Purpose To improve the procedures used to treat prolapse and hemorrhoids, novel magnetic rings were invented to use in circumferential mucosectomies to avoid the disadvantages of stapling techniques. Methods Thirty adult pigs were randomly divided into three groups: Group A ( n  = 10), which underwent circumferential mucosectomy with novel magnetic rings; Group B ( n  = 10), which underwent circumferential mucosectomy with conventional magnetic rings and Group C ( n  = 10), which underwent circumferential mucosectomy with a stapling technique. Results All pigs underwent the operation successfully, and the mean length of the procedure was similar among the three groups ( p  >  0.05 ). There was no bleeding in Group A or Group B, while there was a mean blood loss of 78.32 ± 26.03 ml in Group C ( p
