An apparatus to create continence in an end left-sided colostomy in dogs is assessed. The device consists of a samarium-cobalt magnetic ring encased in methyl methacrylate and a magnetic cap. The ring is implanted in the abdominal wall and the colon delivered through it and matured to the skin. The stoma is later obturated by the magnetic cap to provide continence. Ten dogs exposed to "uncoated" samarium-cobalt magnets for periods of up to eight months showed no elevation of cobalt levels in the serum or tissues and no histopathologic changes on postmortem examination. In twelve dogs, magnetic rings were used to create continent colostomies. Eleven of twelve dogs followed for periods up to eight months were continent and tolerated the appliance well. One ring was extruded after a peristomal skin dehiscence occurred. Two skin strictures appeared and were readily controlled by digital dilatation. Sinus, fistula, or infection were not seen. Clinical application of this device is discussed.
对一种用于使犬左侧末端结肠造口实现节制功能的装置进行了评估。该装置由一个包裹在甲基丙烯酸甲酯中的钐钴磁环和一个磁帽组成。磁环植入腹壁，结肠通过磁环引出并与皮肤愈合成熟。之后用磁帽封闭造口以实现节制功能。十只犬暴露于“未涂层”的钐钴磁体长达八个月，血清或组织中的钴水平未升高，尸检时也未发现组织病理学变化。在十二只犬中，使用磁环构建可控结肠造口。随访长达八个月的十二只犬中有十一只实现了节制功能，并且对该装置耐受性良好。在造口周围皮肤裂开后，有一个磁环脱出。出现了两处皮肤狭窄，通过手指扩张很容易控制。未观察到窦道、瘘管或感染。讨论了该装置的临床应用。
