COVID-19 studies are our top priority. For all other studies, we recommend commencing the registration process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission as we are experiencing 4 week turn-around time in review of submissions and resubmissions. We currently do not have the capacity to expedite reviews.

Note also there are additional delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Participants enrolled in the intervention arm will receive trophic (very low rate) enteral nutrition via a nasogastric tube. The nasogastric tube will be inserted during time of surgery (standard practice). Feeds will commence within 24 hours of surgery using a standard polymeric enteral feed which is already used frequently throughout the hospital. Enteral feeds will run for 20mL/hr (equivalent to one tablespoon every hour) over 24 hours until the participant’s diet is upgraded to full fluids, which will take approximately 3-5 days. Participants will commence TPN (standard practice at this site) the same time enteral nutrition starts. In most patients, the TPN infusion can be commenced at 60mL/h, or at the charted goal infusion rate if the patient has been receiving 5% dextrose at that goal rate for 4 hours and blood glucose levels have been stable. 40mL/h will be used if the patient is
suspected to be at risk of Refeeding Syndrome or glucose intolerance, or if the
patient’s body weight is low. If this happens, biochemistry will be monitored every 4 hours and TPN will be increased as determined by the clinician, using their clinical judgement, at this time point until it reaches goal rate. A combination of TPN and enteral nutrition will meet the participant’s nutritional requirements as determined by the dietitian. TPN will be increased as per standard practice. It should be noted there is currently no evidence for best feeding practice after pelvic exenteration surgery which is why this study is being implemented. If patients do not tolerate enteral feeds indicated by large aspirates identified by nursing staff, enteral feeding will cease.

Comparator / control treatment
Participants enrolled in the control arm will receive standard nutrition care. The definition of standard care is the use of TPN in ICU after their pelvic exenteration. Participant’s nutrition requirements will be calculated and the appropriate rate of TPN will be provided to meet their needs. As previously noted there has been no nutrition studies conducted in this cohort. Standard care is defined as per the site. This highlights the need for this study. The nutrition and medical team will provide the standard care.

Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
25 cards labeled intervention and 25 cards labeled control will be placed in opaque envelopes and randomly positioned in a box by an Associate Investigator. The Chief Investigator will open an envelope within 24 hours after surgery of a recruited participant and assign the participant to the relevant group.

Statistical methods / analysis
All data will be stored in REDCap database and statistical analyses will be performed using SPSS. Characteristics of patients randomised to each group will be compared. The time to first bowel motion will be compared between groups using unpaired two tailed t-tests. Secondary outcomes will be compared between the intervention and the control groups using unpaired two tailed t-tests, anovas and regressions to determine sig. differences between the groups.

Brief summary
The purpose of this study is to determine whether early feeding can help decrease gut side effects in patients who have received surgery for the removal of all pelvic organs (called pelvic exenteration and includes removal of the bladder, urethra, rectum and anus) as a radical surgery for the treatment of cancer.

Who is it for?

You may be eligible for this study if you are an adult who is going to have a pelvic exenteration surgery for cancer and other curative reasons.

Study details

Participants in this study will undergo their surgery as normal, and then during the surgery, will be randomly selected to be one of two groups.
Group 1: Will receive standard nutritional care after the operation.
Group 2: Will receive a feeding tube during the surgery, which will commence providing food within 24 hours from the end of the surgery up until the participant commences a full fluid diet. Tolerance and delivery of nutrition will be monitored.

It is hoped that this research will help determine if it is possible to commence feeding patients after their pelvic exenteration surgery and therefore reduce gut-related side effects.
