Although numerous etiologic risk factors have been proposed, the pathogenesis of hemorrhoids remains unknown. The present investigation assesses the temporal distribution of hemorrhoids as depicted by physician visits, hospital discharges, and surgical procedures to provide further insight into potential etiologic risk factors. The analysis was based on five data sources: from the United States, the National Disease and Therapeutic Index (NDTI), the National Hospital Discharge Survey (NHDS), and the Commission on Professional Hospital Activities (CPHA); from England and Wales, the Morbidity Statistics from General Practice (MSGP) and the Hospital In-patient Enquiry (HIPE). Results demonstrated a consistent decline in all data sources from the United States. The decrease occurred in males and females similarly and was most striking in those aged 45-64 years. Physician visits and hospital discharges for hemorrhoids in England and Wales likewise declined although the decrease was not as dramatic. The consistency of the temporal distributions among the two countries, as well as among the different sources, suggests that the observed decline may, in fact, reflect an overall decrease in the occurrence of hemorrhoidal disease.
尽管已经提出了许多病因风险因素，但痔疮的发病机制仍然未知。本研究通过医生问诊、医院出院记录和外科手术来评估痔疮的时间分布，以便进一步了解潜在的病因风险因素。该分析基于五个数据源：来自美国的国家疾病与治疗指数（NDTI）、国家医院出院调查（NHDS）以及专业医院活动委员会（CPHA）；来自英格兰和威尔士的全科医疗发病率统计（MSGP）和医院住院病人查询（HIPE）。结果显示，美国所有数据源的数据均持续下降。男性和女性的下降情况相似，在45 - 64岁人群中最为明显。英格兰和威尔士因痔疮进行的医生问诊和医院出院记录同样有所下降，尽管降幅没有那么显著。两国之间以及不同数据源之间时间分布的一致性表明，观察到的下降可能实际上反映了痔疮疾病发生率的总体下降。
