Study type
Interventional
Description of intervention(s) / exposure
LigaSure and Gyrus PK are all TGA approved laparoscopic blood vessel sealing devices used in standard hospital care. They have been widely used in laparoscopic surgery for more than 15 years. The safety of these two instruments has been well established in clinical practice. We are evaluating their operative time and blood loss in laparoscopic gynaecological surgery.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
32 patients per study group will be enrolled. Enrolment is defined as completion of informed consent and randomisation. The randomization outcome will be written on a paper and put in numbered opaque envelopes, which will be opened by the surgeons in theatre just before the operation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation scheme, in a block, will be used to generate the randomisation list. The randomisation scheme will ensure that during the enrolment period the ratio of the number of cases in the two groups remain approximately constant.
Masking / blinding

Efficacy
Statistical methods / analysis
Sample size calculation is based on the operative time. The mean operative time in the SWAPS unit (Sydney West Advanced Pelvic Surgery) is 120 minutes with SD 35. As a result, 32 patients are needed in each arm to have 80% of power to detect a 25 minutes difference in operative time at the two sided 5% significance level. Statistics computer program (SPSS statistics standard, Chicago, USA) will be used in carrying out the statistical analysis. The baseline characteristics will be compared by using analysis of variance. Chi-squared, Mann-Whitney or Fisher’s exact test will be used to estimate the significance of difference between discontinuous variables.
