Methods Acute bile duct injury was constructed as a bile peritonitis model in mongrel dogs(n=32). Magnetic anastomosis(group A, n=16) and traditional suture anastomosis(group B, n=16) were performed to reconstruct the biliary-enteric continuity in one stage. Half of the dogs in each group were euthanized on the 30 th postoperative day, and the other half on the 90 th postoperative day to harvest the stoma region. The healing conditions of the stoma after the 2 anastomotic approaches were observed with naked eyes, under light microscope and scanning electron microscope. Results The stoma leakage rate(50% versus 0% on the 30 th postoperative day, 37.5% versus 12.5% on the 90 th postoperative day, both P<0.05) and stenosis degree(13.9%±0.3% versus 7.1%±0.3% on the 30 th postoperative day, 17.2%±0.4% versus 9.4%±0.4% on the 90 th postoperative day, both P<0.01) were significantly higher in group B than in group A. Compared with traditional manual anastomoses, the histological analysis under light and electron microscope showed a more continuous stoma with more regular epithelium proliferation and collagen arrangement, less inflammation in group A. Conclusions Magnetic anastomosis stent ensures better healing of the stoma even under the circumstance of severe inflammation.展开更多
