[Conservative surgery--choice of procedure and strategy: invasive versus minimally invasive surgery]

From the patient's view conservative surgery means less stress and strain through therapeutic interventions. Important criteria for assessment are freedom of pain, preservation of health or quick recovery from bodily impairments as well as reestablishment of integrity and fitness. The surgeon meets the patient's expectations through a careful interview, an operation with a minimally traumatizing access, a rather reliable technique and a careful follow-up. Endoscopic surgery most likely complies with this conception. This is shown in a prospective observational study on laparoscopic cholecystectomies in 500 patients and can also be expected for future indications.
