Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Three groups: Fasting alone vs. minimal residue diet alone vs. mechanical bowel preparation and minimal residue diet.

Fasting alone - see comparator/control treatment below
Minimal residue diet - 1 day before surgery: no solid food or milk products to be consumed, clear fluids allowed. On the day of surgery: for morning surgery patients are advised to eat and drink normally up until the day before surgery and to have nothing to eat or drink from midnight (this includes water) and for afternoon surgery, no solids are allowed after midnight, but clear fluids such as Gatorade and water are allowed until 6am only. Patients will be advised if they are having morning or afternoon surgery.

Full Mechanical Bowel Prep - 2 days before surgery: no solid foods, full liquid diet, milk products allowed. 1 day before surgery: no solid food or milk products to be consumed, clear fluids allowed. One 15.5g sachet of sodium picosulphate (Picoprep) no later than 3pm, and a 2nd sachet 4-6 hours later. Only 2 sachets of osmotic laxative will be used in this study. On the day of surgery: for morning surgery patients are advised to eat and drink normally up until the day before surgery and to have nothing to eat or drink from midnight (this includes water) and for afternoon surgery, no solids are allowed after midnight, but clear fluids such as Gatorade and water are allowed until 6am only. Patients will be advised if they are having morning or afternoon surgery.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Concealment will be maintained by study allocation being accessed though a
central telephone randomisation procedure at the study centre in the Royal Hospital for Women
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocations will be provided using computer-generated randomisation blocks to ensure complete randomisation across demographic fields and to provide a balanced data pool across both groups throughout the trial.
Masking / blinding
Blinded (masking used)
