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.
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.
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.
The innovative magnetic rings we developed for circumferential mucosectomies provide a simple and novel surgical procedure for prolapse and hemorrhoids.
为改进治疗直肠脱垂和痔疮的手术方法，发明了新型磁环用于环形黏膜切除术，以避免吻合器技术的缺点。
将30只成年猪随机分为三组：A组（n = 10），采用新型磁环进行环形黏膜切除术；B组（n = 10），采用传统磁环进行环形黏膜切除术；C组（n = 10），采用吻合器技术进行环形黏膜切除术。
所有猪均成功完成手术，三组手术平均时长相似（p > 0.05）。A组和B组均无出血，而C组平均失血量为78.32 ± 26.03 ml（p < 0.01）。C组发现3例吻合口狭窄（3/10）；B组发现2例（2/10），A组未发现吻合口狭窄（0/10）。A组和C组之间的差异具有统计学意义（p < 0.05）。A组和B组磁环的成本明显低于C组吻合器技术的成本（分别为20.12 ± 3.35美元、15.76 ± 2.92美元和550.16 ± 29.71美元，p < 0.001）。A组和B组的磁环在1 - 2周内随坏死组织自行排出体外（分别为8.20 ± 2.73天和9.31 ± 3.62天，p > 0.05），避免了C组吻合器的永久植入。A组吻合口部位的愈合过程比B组或C组更平滑、更快。
我们为环形黏膜切除术开发的创新磁环为直肠脱垂和痔疮提供了一种简单新颖的手术方法。
