Patients are allowed to sleep during gastroscopies and colonoscopies

  • We offer the examinations under sedation (pleasant and safe short sleep due to the drug propofol). This means that the examination is not experienced consciously. It is not a question of anaesthesia. Of course, an examination while awake is also possible upon request.
  • Please note that driving a motor vehicle is not allowed for 12 hours after sedation. Therefore, organise your journey home by relatives or by nearby public transport. For the examinations, a total of approx. 1 1/2 h should be planned.
  • The top priority is to carry out the examination safely and gently. Please help and follow the instructions for preparation sent with the summons exactly.
  • You will be instructed by us by telephone or in writing before each examination about what you need to pay special attention to: please call us if you are unclear. You are also welcome to arrange a consultation with Dr Riniker before the examination appointment.

  • Hemorrhoidal complaints (itching, bleeding, swelling and burning at the anus) are common and often easily treatable.
  • Out of shame and fear, going to the doctor is often unnecessarily delayed.
  • Contact us unabashedly and let us advise you.
  • An examination of the anus runs discreetly, requires no preparation, is performed quickly and is painless.

After the retirement of Mrs Dr. van den Brandt in summer 2018, the patient files are available in electronic form in my practice until the 10-year retention period expires. I ask you to request older endoscopy reports by mail. Lab results, histology results and KG notes are not available. Histology results can be requested from the Institute for Histological and Cytological Diagnostics AG Aarau.
