Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention Group – Early enteral nutrition (EEN)
Oral feeds will be offered within 24 hours of admission to the recovery room.
- Nasogastric Tube (NGT) is removed in theatre or in recovery
- First feed is clear fluids, as tolerated
- Subsequent feeds full fluids ad lib, as tolerated, entirely parent/carer/patient led.
- Commence solids within 48 hours of admission to the recovery room ad lib, as tolerated, entirely parent/carer/patient led.
- Vomiting – fast 4 hours then recommence clear fluids as above unless clinically contraindicated.
- Adherence will be monitored using a bedside data sheet that will be filled out by the nursing staff.

Treatment: Other
Comparator / control treatment
Control
- NGT remains in place post operatively
- Commence feeds on return of bowel function or when aspirates are no longer green. Return of bowel function is defined as the passage of flatus or stool or once NGT aspirates have become non-bilious, typically after around 2-3 days of fasting.
- Start with clear fluids as tolerated
- Remove NGT as per surgeon
- Grade up through full fluids and solids as tolerated, as in the EEN group.

Eligibility
Key inclusion criteria
Paediatric patients between the ages of 3 months and 16 years who can be expected to feed orally after undergoing elective enterostomy closure for the following indications and operation type;
- Elective closure of colostomy after Anorectal malformation (ARM) repair
- Elective closure of colostomy/ileostomy after pull-through for Hirschsprung's disease (HSCR)
- Elective closure of ileostomy after previous neonatal laparotomy for Necrotising enterocolitis (NEC), perforation, atresia or other intestinal pathology
- Elective closure of colostomy/ileostomy where the stoma was formed at a previous laparotomy for other intra-abdominal pathology.
Minimum age
3 Months
Maximum age
16 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
• Patients with short gut requiring long term total parenteral nutrition (TPN)
• Patients undergoing a total colectomy or gastrostomy closure
• Intercurrent conditions expected to affect bowel function (e.g., neurological impairment)
• Patients who have been assessed to have unsafe swallow or laryngeal penetration with reflux and vomiting. This includes inability to protect the airway due to neurological impairment or structural abnormality, due to aspiration risk
• Inability to obtain consent from parent/guardian
• Patients requiring specific individualised feeding regime (e.g., metabolic disease)
• Patients who require prolonged nasogastric tube (NGT) feeding
• Patients requiring more than a simple enterostomy closure; i.e., extensive adhesiolysis or more than one anastomosis (in NEC)
• Patients with Cystic Fibrosis or Inflammatory Bowel Disease.

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)
Allocation concealment is achieved as randomisation will occur once the child arrives in the recovery room. Thus, when assessing whether patients are eligible for inclusion in the trial, investigators will not know which group the patient will be allocated to. Further, by randomising immediately after surgery, the surgeons will not know which group the patient will be allocated to. Upon admission to the recovery room, randomisation will occur by using sealed opaque envelopes that have been prepared in advance by a biostatistician.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified permitted block randomisation will be prepared by a biostastician. Patients will be stratified by type of stoma closure (small bowel stoma closure vs colostomy closure), hospital type and age (3 months - 5 years vs 6 years - <16 years), giving a total of 8 blocks.

Statistical methods / analysis
A sample size of 40 patients is required for this study. We are planning a RCT, with the outcome measure being continuous length of stay, comparing 2 independent groups: control and EEN patients with 1 control per EEN patient.

Analysis will be performed according to the intention-to-treat principle, whereby participants are analysed in their randomised treatment group, regardless of the treatment they received. Continuous variables will be characterised by mean and standard deviation for normally distributed data and median and interquartile range for non-normally distributed data. They will be compared using an independent sample T-test if normally distributed and Mann-Whitney U test where not normally distributed. Time to full feeds and passing of stool will be described using Kaplan Meier survival analysis and compared using the log-rank test.

Categorical variables will be characterised by frequencies and percentages and compared using Chi-square test, and Fishers exact test where cell size is less than 5.

Sample size justification
In a previous study mean LOS was 7.2 and 9.4 days within early feeding and standard care groups, respectively, with a standard deviation of 2.1. Historical data in our clinic showed mean (SD) LOS of 3.67 (0.99) and 5.91 (2.5) days in 17 patients offered full feeds within 48 hours of surgery and 18 patients offered full feeds more than 48 hours after surgery, respectively. This reduction in LOS is considered clinically important. A study of 34 participants randomised 1:1 will have 80% power at 5% two-sided alpha to detect a difference of one standard deviation in the mean of a normally distributed outcome. To account for some withdrawal and loss to follow up, we plan to recruit a total of 40 patients.
