Endosonography of the stomach and esophagus (ÖGD)
Endosonography of the respiratory tract (endobronchial ultrasound)
Endobronchial ultrasound is a very safe procedure, but occasionally it can cause airway injury and bleeding during tissue removal.
Transvaginal endosonography
The advantage of transvaginal endosonography over conventional ultrasound examination through the abdominal wall is that it provides better images due to the proximity to the organs. In addition, just like conventional ultrasonography through the abdominal wall, transvaginal ultrasonography does not pose any particular risks and is only somewhat uncomfortable, not painful, for the patient.
