Do we need the overtube for push-enteroscopy?
The use of an overtube in push-enteroscopy is advantageous with respect to the depth of insertion (significant difference between group T and NT in counted folds and the insertion depth in centimeters). At this time, this gain of insertion length did not result in a higher rate of pathological findings. Nevertheless, we would recommend the use of an overtube in performing push-type enteroscopy in order to increase the number of pathological findings.
VPA may diminish gonadotropin release in vitro but this effect can only be achieved after GnRH-dependent specific receptor activation. Both gonadotropins differ in their pattern of response for increasing doses of VPA.
