About the department

The department of general, abdominal and bariatric surgery at Academic Hospital Sachsenhausen Frankfurt am Main offers the diagnosis and treatment of abdominal conditions that require surgical solutions. The approach is always minimally invasive and interdisciplinary. More than 85 per cent of all surgical interventions in the department are performed minimally invasively. In addition to specialisations in general and accident surgery, the department is one of the leading centres in Germany in bariatric surgery. Although the surgeon's "main work" takes place in the operating room, the treatment can only be successful if the patient is accompanied by structured preoperative and postoperative care. The treatment planning is coordinated with general practitioners and other colleagues, while trained nursing staff take care of the patient's comfortable stay in the hospital. Emergency assistance is available around the clock.

The main direction of the department is the surgical treatment of inflammatory diseases and oncological diseases of the visceral organs. The treatment concept ranges from the preliminary examination, through the operation, to the follow-up check-up and, if necessary, a plastic surgery.
