This randomised controlled trial was approved by the Research and Development department and the Local Research Ethics committee. We performed a pilot evaluation of ten-day average pain and expectation scores after LH in 7 patients. Based on the data from this pilot study and the average pain scores from the literature for GH, we calculated a requirement of 40 patients to give a 90% power to the study at the 5% significance level (student's t-test) to detect a 22% difference in 10 day average pain scores with a standard deviation of 1.712. Null hypothesis was that there was no difference in the pain scores between the two groups.
