About us

Dr Hani Oweira is a specialist in surgery and bowel surgery and works as a visiting surgeon at the Andreas Hospital, Cham, Zug and as an associated partner at the Surgical Centre, Zurich. He completed his medical training and specialist qualification at the renowned University hospitals in Heidelberg and at the Berlin Charité. Prior to his current position, Dr Oweira held a position as a consultant at the Hirslanden Surgical Centre clinics of the Hirslanden Hospitals.

Dr Oweira’s clinical focus is on the surgical treatment of inflammatory conditions and tumours of the gastro-intestinal tract and hernia surgery (inguinal and incisional hernias). Dr Oweira also possesses great expertise in complex tumour surgery to all abdominal organs. He utilises the most up-to-date techniques applied in the treatment of cancer with the greatest degree of competence and safety. These include HIPEC, PIPAC and the NanoKnife technique.

HIPEC stands for Hyperthermic Intraperitoneal Chemotherapy and this has proven greatly successful in the removal of the smallest vestiges of tumour tissue on the peritoneum. This method takes advantage of the fact that tumour cells are more sensitive to heat than the body’s healthy cells.
Following the surgical removal of the primary tumour, a chemical preparation is heated to over 40° C and is placed in the abdominal cavity. Here, it attacks the remaining tumour cells in particular and kills these off. In this manner, particular tumours can be targeted and treated without the known side-effects due to chemotherapy.

For certain forms of tumour in the abdominal cavity which are not suitable for the HIPEC technique, Pressurised IntraPeritoneal Aerosol Chemotherapy (PIPAC) can produce good results. Here, the medication is introduced to the site in a gaseous form in the course of a laparoscopy. This technique has only been in use since 2011 but has already shown very good results.

Another new and extremely precise technique which Dr Oweira utilises in cancer therapy is the so-called NanoKnife technique. Using very brief and locally sharply delimited current pulses, this can destroy tumour cells in a targeted manner in prostatic cancer, without producing heat and without damaging the surrounding healthy tissue. Hence, side-effects such as incontinence, which frequently appear due to procedures on the prostate gland, can often be avoided.

Thanks to his skill in the practical application of promising new techniques, Dr Oweira is among the pioneers in this field. To date, he has published several contributions in the national and international specialist scientific literature and is also an active participant in relevant European specialist associations.
