Even today, the etiology of proximal tubal occlusion is still a controversial subject. The introduction of microsurgery in gynecology has provided a method of eliminating the main symptom of proximal tubal occlusion, i.e., sterility. Pregnancy rates of 25-30% can be achieved in overall patient collectives. Accurate histologic analyses of the specimens are essential for clinicopathological classification in three prognosis groups. For stage I patients, pregnancy rates of up to 50% (patient-related) can be achieved. Postoperative counseling can thus be differentiated on the basis of the histological results. For stage III patients the pregnancy rate is unlikely to be acceptable, even after waiting for a prolonged period of time. It has not been established whether reconstructive tubal surgery or alternative therapeutic procedures (I.V.F. and E.T.) have better chances of success in stage II. Accurate histologic analysis of the surgical specimens is an essential prerequisite for individualized sterility counseling and therapy.
即便在今天，近端输卵管阻塞的病因仍是一个存在争议的话题。妇科显微手术的引入提供了一种消除近端输卵管阻塞主要症状（即不育）的方法。在总体患者群体中，妊娠率可达25% - 30%。对标本进行准确的组织学分析对于分为三个预后组的临床病理分类至关重要。对于I期患者，（与患者相关的）妊娠率可达50%。因此，术后咨询可根据组织学结果进行区分。对于III期患者，即使经过长时间等待，妊娠率也不太可能令人满意。目前尚未确定在II期，输卵管重建手术或替代治疗程序（体外受精和胚胎移植）是否有更好的成功机会。对手术标本进行准确的组织学分析是个体化不育咨询和治疗的必要前提。
