Description of intervention(s) / exposure
This randomized controlled trial will investigate the efficacy and safety a novel stoma output recycling pump for patients undergoing elective reversal of their loop ileostomy.

The device is a centrifugal pump (impeller) housed within a stoma appliance and connected to an enteral feeding tube placed inside the distal limb. The pump is activated on-demand (as individually indicated by a specific patient's daily output volume) to achieve bolus refeeding, using a battery-powered driver with 5 speed settings. The correct speed setting is determined by the viscosity of the patient's chyme.

The device will be used in patients who are at least 2 weeks post-loop ileostomy formation, have confirmation of adequate downstream anastomosis healing via radiological investigation, and are at least 2 weeks away from having their ileostomy reversed.

Patients are fitted with this device in the outpatient clinic by a study investigator (who will be either a surgical registrar/consultant or stoma nurse) after enrolment, are carefully educated on how to use it, undergo a trial run with plain water in the stoma bag, and then are sent home with an information sheet and contact details of the study team if any issues arise.

The device will be used during the waiting period for ileostomy reversal (weeks to months) with the frequency of use determined by the individual patient's stoma output per day.

The per-protocol population will include all those allocated to using the device and have used it continuously daily for a minimum period of 2 weeks directly prior to the surgery date. The intention to treat population will include all those allocated to using the device and have used it at least once.

Strategies to encourage adherence:
The research team will be in regular contact with the patient to assess and encourage device usage. Patients will also self-report device use in standardised logbook diaries.

Comparator / control treatment
The control group will be patients who are at least 2 weeks post-loop ileostomy formation, have confirmation of adequate downstream anastomosis healing via radiological investigation, and are at least 2 weeks away from having their ileostomy reversed but do not receive the stoma-output recycling device and continue standard care prior to reversal surgery.

Statistical methods / analysis
Analysis of the primary outcome will be to compare the time from admission to discharge measured in days between patients who have used the stoma-output recycling device and those that did not. Statistical significance will be determined using unpaired t test as we believe the data will be parametric. This analysis will be performed on the intention-to-treat population primarily with a subset analysis on the per-protocol group.

Secondary categorical outcomes will be analysed using the Chi-squared test or Fischer’s exact test where appropriate. Secondary continuous variables will be analysed using unpaired t test (reporting mean and standard deviation) and Mann Whitney U test (reporting median and interquartile range) for parametric and non-parametric data, respectively. Statistical testing of secondary outcomes may not be valid as specific power calculations have not been performed for each individual secondary outcome.

Summary
Brief summary
The intervention group of this randomised controlled trial will utilize a novel stoma-output recycling device to reinfuse the bowel fluid from the patient’s loop ileostomy into the distal limb.

The aim is to determine if stoma-output recycling will reduce post-operative length of stay as well as improve pre-operative quality of life, chemotherapy-related outcomes and post-operative recovery of bowel function for patients undergoing elective reversal of their loop ileostomy.

We hypothesize that stoma-output recycling will reduce the length of post-operative stay and provide better pre-operative quality of life, chemotherapy-related outcomes and faster recovery of bowel function.
