Stanek及其同事注意到:不吸收的缝合材料吻合结肠会促使结肠形成赘生物和使吻合肿块增大。据此,作者把术前用氧化偶氮甲烷治疗的老鼠,用不同的材料吻合其结肠,观察这些不吸收缝合材料对肿瘤发生的影响。实验证明:吻合部位的肿瘤发生率要比其他部位高。但是用丝线、丹克森(Dexon)或铬制 Stanek and colleagues note that the non-absorbed suture material in the colon causes the colon to form neoplasms and enlarge the anastomosis. Based on this, the authors used rats treated with azoxymethane to agglutinate their colons with different materials and observed the effect of these non-absorbable suture materials on tumorigenesis. Experiments have shown that the incidence of tumors at the site of anastomosis is higher than that of other sites. But with silk, Dexon, or chrome
