Our approach
Surgery through small cuts
Minimal access (keyhole) surgery uses a camera and fine instruments through small incisions. Compared with open surgery, it usually means less pain, smaller scars, a shorter hospital stay and a quicker return to work. Bariatric surgery is a tool for people with severe obesity and related health problems, combined with long-term diet and lifestyle change.
- Keyhole surgery for common abdominal problems
- Bariatric assessment with physicians, dietitians and endocrinologists
- Anaesthesia and ICU support on the same campus
- Clear discussion of options, risks and costs
- Follow-up and diet support after surgery
