Abstract:
Clinical trials are required in surgery to evaluate existing procedures and to assess the value of new techniques. Except for observational studies which are considered useful only to propose a hypothesis, all study designs require a comparator group. The randomised controlled trial (RCT) is recognised as the most robust study design. There are specific ethical difficulties in conducting RCTs.
