The practice is growing, which is gratifying.

  • Since November 2017, I have been supported by Ms. med.pract. Anne Oberle, who has been a specialist in gastroenterology since March 2019.
  • The experienced radiologist Dr Beat Rehmann joined the team in September 2019. Thanks to him, we can offer faster appointments for abdominal sonography and expand the spectrum of sonographic diagnostics to include thyroid, vessels, hernias and soft tissues.
  • Since January 2020, the gastroenterologist Dr Susanne Flückiger has complemented our team with her extensive knowledge in the clarification of motility disorders, pH-metry and coeliac disease.
  • Since March 2022, the experienced gastroenterologist Dr. Irene Guldenschuh has completed our practice.

Image documentation and reporting are digitised. The reports are usually produced without picture inserts, pictures can be sent electronically on request. Please do not hesitate to let me know your wishes regarding the dispatch or scope of the reports.

After Dr van den Brandt‘s retirement in summer 2018, the patient files will be available in electronic form in my practice until the 20-year retention period expires. I kindly 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.

As an independent, free practice, we maintain a good relationship with surgical and gastroenterological colleagues at all hospitals in the extended region, so that the best treatment option can be found for each patient without bias. The family doctor is involved in the decision-making process.
