Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Anastomosis versus stoma formation.
Both procedures are used in standard surgical practice for necrotizing enterocolitis, the choice (in babies meeting the inclusion criteria of the present study) is determined by the surgeon's preference. Allocation of the terms "intervention" and "comparator" are therefore arbitary; for this section we will discuss stoma under intervention and anastomosis under comparator.
The whole operation (including and anaesthetic, the cut to open up the abdomen, removal of the diseased bowel and dealing with the two ends) takes about 2-3 hours. After removing the diseased bowel, the two ends are joined together using stitches. A potential complication of an anastomosis is that it can leak and cause peritonitis or an abscess. This occurs uncommonly.
Intervention code [1] 257908 0
Treatment: Surgery
Comparator / control treatment
A stoma is an opening of bowel onto the skin. As for an anastomosis, the whole operation takes about 2-3 hours. After removing the diseased bowel either one or both of the cut ends are sewn to the skin so bowel contents can leak into a bag. Some surgeons think a stoma may be "safer" than an anastomosis because it should not leak. The A further operation later on when the baby's condition has improved is necessary to close the stoma. A stoma however can cause several complications itself, such as prolapse.

Respiratory function.
Timepoint [10] 268948 0
This will be assessed by the need for assisted ventilation ie oxygen requirement, CPAP or intubation for ventilation.
Spirometry is not performed as a routine therefore will not be used to assess respiratory function in this study.
This will also be assessed (eg need for supplimentary oxygen) at 1, 3 and 6 months and 1 year.

This will be calculated from standard measures including lenght of neonatal intensive care unit stay, length of total hospital stay, number of operations and number of interventions. These will be recorded on the data forms.

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)
Potential participants will be identified by consultant paediatric surgeons and neonatologists. The paediatric surgeon will describe the trial to the neonate's parent(s)/care giver(s) at the time of getting consent for the study.
Randomization will be done on-line in theatre at the time of confirmation that both stoma and primary anastomosis are feasible. Theatre staff will login to the STAT trial website. The surgeon who invites the participant onto the trial and performs the surgery will be unaware of which group a patient will be allocated to at the time of determining eligability. The allocation occurs through a central computer at the Institute of Child Health in London.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be allocated to groups by weighted minimization using the following criteria: Weight at enrolment; Mechanical ventilation required; Inotropic support required; Extent of disease; Intestine involved.
