ZweiChirurgen celebrating 2-year anniversaryExactly two years ago at the 5th November 2018 ZweiChirurgen started their practice and treated the first patients in the heart of Basel.We would like to thank all patients, referring doctors and colleagues for their trustful collaboration.
ZweiChirurgen with exciting publicationTogether with colleagues from Germany and Austria PD Dr. Henry Hoffmann from ZweiChirurgen has investigated the trends in incisional hernia repair in the last decade using data from the European Herniamed registry. The result was surprising but also expected: the new minimally invasive techniques such as MILOS are on the rise. In contrast to the conventional laparoscopic techniques, the implanted mesh to support the abdominal wall is moved from inside the abdominal cavity to an extraperitoneal layer behind the abdominal wall muscles to avoid contact with the viscera. Therefore, the MILOS repair is the standard for the repair of ventral hernias at ZweiChirurgen.link to the article
ZweiChirurgen with important publicationTogether with colleagues from all over the world Prof. Dr. Kirchhoff from ZweiChirurgen has published a very important work in the highly ranked medical journal «BMJ». Analyzing more than 2500 operations the researcher team developed a classification of intraoperative complications, called IntraClass. Based on this new classification system intraoperative complications can be assessed more easily, and subsequent postoperative management of surgical patients can be improved to enhance patient safety. Results of the study and the evaluated classification were also convincing to the Swiss Academy of Quality in Medicine (SAQM), which awarded this work with the «Innovation Quality Price» 2020 in the category patient safety.Read the article (pdf)Article on BMJ (pdf)

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.
The seal «Quality assured Hernia Surgery» was awarded to us by the Deutsche Herniengesellschaft
