One cause of post-operative morbidity in the elective repair of abdominal aortic aneurysms is the development of a paralytic or 'adynamic' ileus. In a series of 20 consecutive patients undergoing such a procedure, the maintenance of small bowel motility and absorptive capacity in the immediate post-operative period was assessed using barium sulphate and xylose passed down a naso-duodenal tube sited at the time of surgery. This simple study demonstrated that small bowel function was preserved in all cases, and hence that patients could be fed enterally via naso-duodenal tube (in particular using very low residue formulae) rather than using costly parenteral regimens, should an ileus persist.
腹主动脉瘤择期修复术后发病的一个原因是麻痹性或“动力缺乏性”肠梗阻的发生。在连续20例接受此类手术的患者中，通过在手术时放置的鼻十二指肠管注入硫酸钡和木糖，评估术后即刻小肠的运动和吸收能力。这项简单的研究表明，所有病例中小肠功能均得以保留，因此，如果肠梗阻持续存在，患者可通过鼻十二指肠管进行肠内喂养（特别是使用极低渣配方），而非采用昂贵的肠外营养方案。
