Some babies require emergency surgery on their tummy in the first few months of life. This is most commonly because they were born prematurely and developed a bowel problem (called NEC) or a blockage of the bowel. As part of this surgery, the ends of the bowel may be brought to the skin surface (called a stoma) to divert stool into a bag. The stoma allows time for the bowel to rest and recover and is intended to be temporary with reversal later on. The best time to reverse or close the stoma is unknown. Stomas may cause dehydration, poor growth and skin problems so earlier closure may be better; however surgery is safer when babies are older and bigger so later closure may be better. This study aims to answer the question, 'is it feasible to conduct a clinical trial comparing 'early' vs. 'late' stoma closure in neonates?' It has a series of specific objectives which incorporate: (i) describing current UK practice; (ii) establishing whether or not a clinical trial (and exactly what form of trial) is acceptable to parents and clinicians; and (iii) establishing the design of a potential trial, including defining the intervention ('early vs. late') and the population of infants to be included, how infants should be recruited and what information should be collected (outcomes). The investigators will ask parents and health professionals for their views and whether they would take part in a future trial and information about babies who have recently had a stoma to find out which factors influence the timing of closure. They will also analyse 6 years of data from an existing database, the National Neonatal Research Database to estimate the numbers of babies affected, understand current practice and outcomes for these babies to help decide whether a clinical trial is possible.

Neonates undergoing emergency abdominal surgery frequently require stoma formation. Reversing (closing) these stomas with a second operation is an essential part of the infant's recovery. The timing of this closure is highly variable around the United Kingdom (UK) and the best time remains unclear. Current evidence is of low methodological quality and presents mixed conclusions: determining the best time has significant potential benefits for: (i) infant health outcomes (short-term e.g. avoiding complications and long-term e.g. growth and neurodevelopment); ii) families (e.g. reduced Neonatal Intensive Care Unit (NICU) stay); and iii) healthcare providers (e.g. reduced costs). Ideally, a clinical trial to compare early and late closure would be conducted but this is likely to be challenging and may not be feasible or acceptable to parents and clinicians. Aims and objectives: This study aims to answer the question, 'is it feasible to conduct a clinical trial comparing 'early' vs. 'late' stoma closure in neonates?' It has a series of specific objectives which incorporate: (i) describing current UK practice; (ii) establishing whether or not a clinical trial (and exactly what form of trial) is acceptable to parents and clinicians; and (iii) establishing the design of a potential trial, including defining the intervention ('early vs. late') and the population of infants to be included, how infants should be recruited and what information should be collected (outcomes). Methods: The study will use a mixed-methods approach comprising three parallel workstreams (WS). WS 1 will be a national survey of clinician perspectives of neonatal stoma closure. WS 2 will use an observational cohort study, interviews, questionnaires and focus groups. WS 3 will analyse three existing large databases (National Neonatal Research Database (NNRD), Health Episode Statistics (HES) and British Association of Paediatric Surgeons Congenital Anomalies Surveillance System (BAPS-CASS)). The findings of these WS will be combined and presented at a final, trial design meeting where conclusions about trial feasibility will be reached and if appropriate, an outline of a trial protocol agreed. Anticipated impact and dissemination: The principal impact will be determining whether or not a definitive trial can go ahead: if the study demonstrates that a trial is feasible then the investigators will use their findings to design a trial that is acceptable to parents and clinicians; that includes the most appropriate infants; that measures outcomes important to parents and clinicians and ultimately, answers the question: when is the best time to close an infant's stoma? Findings will be disseminated at national meetings of relevant professionals, through social media (including patient groups), to funding bodies and in open access publications.
