Difficulties with bowel function are common and may be due to several causes including slow colonic transit and obstructed defecation. The anatomical and pathophysiological changes associated with these conditions are varying, often incompletely understood, and in many cases have limited treatment outcomes. Patients present with variable complaints and have previously tried a plethora of over-the-counter medications in an effort to relieve their symptoms. Physicians need an organized approach to manage these patients optimally. Improvements over the past few years in our understanding of the complex process of defecation, along with the increasing use of radiological and anorectal physiology studies, have led to improved treatment results.
肠道功能障碍很常见,可能由多种原因引起,包括结肠传输缓慢和排便受阻。与这些情况相关的解剖学和病理生理学变化各不相同,常常未被完全理解,而且在许多情况下治疗效果有限。患者有各种各样的症状,此前曾尝试过大量非处方药物来缓解症状。医生需要一种有组织的方法来对这些患者进行最佳管理。在过去几年里,我们对复杂排便过程的理解有所进步,同时放射学和肛肠生理学研究的应用越来越多,这使得治疗效果得到了改善。
