Abstract

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 < 0.01). Three cases of anastomotic stenosis were found in Group C (3/10); two cases were found in Group B (2/10) and no anastomotic stenosis was found in Group A (0/10). The difference between groups A and C was statistically significant (p < 0.05). The cost for the magnetic rings in groups A and B was noticeably lower than that of the stapling techniques in Group C (20.12 ± 3.35 vs. 15.76 ± 2.92 vs. 550.16 ± 29.71 US dollars, p < 0.001). The magnetic rings in groups A and B were spontaneously discharged from the body with the necrotic tissues within 1-2 weeks (8.20 ± 2.73 vs. 9.31 ± 3.62 days, p > 0.05), avoiding the permanent implantation of staples in Group C. The anastomosis site in Group A showed a smoother and more rapid healing process than that in Group B or C.

Conclusions: The innovative magnetic rings we developed for circumferential mucosectomies provide a simple and novel surgical procedure for prolapse and hemorrhoids.
