Minimalinvasiven

Minimalinvasiven is a term used in medical contexts to describe techniques that minimize tissue disruption compared with open surgery. The concept encompasses approaches in surgery, interventional radiology, and endoscopic therapy that rely on small incisions, natural orifice access, or image-guided instruments to treat disease while reducing trauma to surrounding tissues.

Common methods include laparoscopy (abdominal procedures through small ports), thoracoscopy, endoscopy, percutaneous catheter-based interventions (angioplasty, stenting, ablations), and robotic-assisted surgery. Innovations such as NOTES (natural orifice transluminal endoscopic surgery) and single-incision approaches further expand access with fewer ports.

Benefits typically cited for minimally invasive approaches are reduced postoperative pain, shorter hospital stays, quicker return to normal activities, smaller scars, less blood loss, and lower risk of wound infection. However, MIS is not universally applicable; some conditions require open surgery for adequate exposure, oncologic clearance, or safety. MIS procedures can have longer operative times, require specialized equipment and training, and carry unique risks such as port complications, CO2-related effects, or incomplete resection, sometimes necessitating conversion to open surgery.

Patient selection and surgeon expertise are key determinants of outcomes. Evidence supports MIS advantages in many abdominal, thoracic, gynecologic, urologic, and cardiovascular procedures, though results vary by procedure and setting. The term "minimalinvasiven" reflects a broader medical trend toward less invasive diagnostic and therapeutic options driven by technology, imaging, and targeted therapies.
