An introduction to minimally invasive therapy

Minimally invasive therapy (MIT) has as its basic premise the reduction of iatrogenic trauma to the patient by surgeon, physician or radiologist. This approach must also imply that the therapeutic procedure succeeds in its aim of cure in a manner no less effective than is currently achievable by established methods of treatment. Acceptance of this principal has many identifiable sequelae, including profound changes in hospital design, increasingly expensive technological instrumentation, more sophisticated teaching and learning patterns, and a massive redirection of health care financial resources. These changes cannot be contemplated at leisure, because they are dynamically imperative and progressing with relentless rapidity, being directly driven by the consumer. It is vital that this shift in clinical emphasis should be appreciated so that future planning can be undertaken with some rationality.
