PD Dr. Philipp Kirchhoff

Philipp Kirchhoff is a specialist in coloproctology and hernia surgery and teaches as a lecturer at the University of Basel.

From 1996 to 2003 he studied medicine at the Universities of Freiburg, Vienna, Yale and Berlin. Philipp Kirchhoff began his surgical training at the University Hospital of Zurich and worked at various Swiss hospitals during his training.
After obtaining his specialist title in surgery, he completed two years of research at Yale University (New Haven, CT USA). There he developed a new drug for the treatment of heartburn as part of his project. After his return, he worked as a senior physician at the Clinic for General and Visceral Surgery at the University Hospital of Basel since 2010 and habilitated in 2011 based on his research on "The Regulation of Gastric Acid Secretion".
Philipp Kirchhoff subsequently completed a clinical fellowship at Cambridge University (U.K.) with a focus on minimally invasive colon surgery and proctology. In this field, he subsequently obtained the European Coloproctological Specialization (ESBQ). Until 2018 Philipp Kirchhoff was the senior consultant at the Clinic for Visceral Surgery at the University Hospital of Basel where he was in charge of general and private patients, resident training and department management.

Philipp Kirchhoff is the inventor and developer of KORING^®, a polyurethane ring device for the prevention of parastomal hernias. His surgical focus is on the surgical treatment of rectal diseases and hernia surgery. He is a reviewer of several international professional journals and a member of numerous surgical societies (SGC, SGVC, DHG and EHS) and international professional committees.

Together with his colleague PD Dr. med. Henry Hoffmann he is the founder of the Swiss Hernia Days. Philipp Kirchhoff speaks fluent German and English.

PD Dr. Henry Hoffmann

Henry Hoffmann is a specialist in surgery, a doctor of medicine and a private lecturer at the University of Basel.

After completing his surgical specialist training in Switzerland, he worked from 2013 to 2018 as a senior physician in the Clinic for General and Visceral Surgery at the University Hospital of Basel. In 2011/2012, PD Dr. Hoffmann completed a clinical fellowship in Great Britain, where he received further training in colorectal and hernia surgery. He then completed a year of research focusing on minimally invasive surgery and VR simulation in surgery.

During his many years as a consultant at the University Hospital of Basel, he successfully managed projects aimed at improving patient safety, speeding recovery from abdominal surgery and quality assurance in hernia surgery. He is particularly interested in quality-assured hernia surgery, and the treatment of sportsmen's groin and chronic groin pain.

PD Dr. Hoffmann holds a certificate of competence in "Laser Treatment of the Skin and Mucous Membrane" (Type I and II), co-founded the Swiss Hernia Days, is a reviewer of several internationally renowned specialist journals and a member of numerous surgical societies (SGC, SGVC, DGCH, DGAV, DHG and EHS). Henry Hoffmann is fluent in German, English and Italian.

Katja Ulrich, MPA

Katja Ulrich completed her training as a medical practice assistant at the Woodtli School in Zurich.

She gained her first practical experience in a general family practice. She was then employed in a physiotherapy practice and finally worked in a large private orthopedic-surgical clinic in Basel. During this time she was responsible for, among other things, planning and coordinating the appointments of the numerous surgeons and surgeries.

Ms. Ulrich is fluent in German, French, English and Italian.

Hernia Surgery

A hernia is a defect in the abdominal wall from which the contents of the abdomen protrude outwards from under the skin. Patients generally see a swelling and have discomfort or pain. Hernias are the most common surgical indication, and around 20,000 hernia operations are performed throughout Switzerland every year. The inguinal hernia is the most common, followed by hernia of the abdominal wall (e.g. umbilical hernias, scar hernias) flowed by rare causes such as flank hernia and diaphragmatic hernias.

At our centre for hernia surgery we offer you competent and tailor-made advice and diagnostics. Depending on the clinical picture and the individual requirements of our patients, we perform open (larger skin incision) and minimally invasive surgical techniques (keyhole surgery) in accordance with current scientific findings and guidelines. Our many years of surgical experience enable us to offer you a surgical technique tailored to your needs. We perform our operations at our exclusive partner, Hirslanden Klinik Birshof in Münchenstein. This highly regarded hospital is well connected to public transportation and located 10 minutes away from our office by car.

In addition, we have specialized in the treatment of sportsmen's groin, chronic groin pain after hernia operations and rectus diastasis. These diseases are complex and must be treated together with other specialists and therapists. Here we can rely on a network of experienced sports physicians, physiotherapists, radiologists and pain therapists.

Our patients are also individually cared for and treated by us after the operation. We remain available for you at all times. Within the framework of our "quality-assured hernia surgery", we also send out follow-up questionnaires after the operation in order to identify new problems early on and treat them professionally.
