[Morphology of the tubal drainage angle of the human uterus and of the pars intramuralis of the tuba uterina].

The morphology of the pars intramuralis of the fallopian tube has been histological examined in 500 uteri which were exstirpated in the Department of Gynaecology and Obstetrics of the University of Kiel in the years of 1972 to 1973. It was found that the interstitial pars of the endometrium changes regularly during the menstrual cycle. In the same way the endometrium in the interstitial part of the tubal canal suffers from an atrophy if patients were treated with gestagens. The adenomatous hyperplasie or the polypes of the endometrium which are often found near the utero-tubal junction are to be considered as the matrix of the carcinoma of the endometrium; continuous changes between the adenomatous hyperplasie and the carcinoma of the endometrium can be observed. The frequency of precancers near the utero-tubal junction underlines the demand for an accurate curettage in this region of the cavum uteri. The histological examination of the region of the utero-tubal junction after the extirpation of the uterus is absolutely necessary and has to be generally to be asked for.
