Description of intervention(s) / exposure
Exposure group = infants </=30 days corrected gestational age undergoing surgery and formation of a gastrointestinal stomas (gastrostomies, small bowel enterostomies, colostomies) undertaken during the minimum 3-month recruitment period). Information collected includes demographics, clinical status, operation performed and any complications. No active involvement of participants: all data collected from medical records. Period of observation is 3-month period September-November 2022, with a 3-month follow-up period December 2022 – February 2023

Statistical methods / analysis
Data will be analysed using Prism (GraphPad Software, San Diego, CA; USA). Data will be screened for duplicates and these removed. Missing data for co-variates will be dealt with by running a) complete case analysis and b) using multiple imputation to allow inclusion of cases with missing data.
A formal power calculation was not performed for this observational study due to the rates of complications and practice in Australia and New Zealand being unknown and the goal of characterising practice and outcomes here. Based on published case series and the number of centres involved, the expected cohort would total approximately 50 infants.
Summary statistics for the demographic data will be calculated, i.e. median and interquartile range for birthweight, weight at operation, gestational age, corrected age at operation, type of stoma for each indication, median longevity of stomas closed during the study period).

Significant differences in complications between indications will not be calculated as this would likely represent an oversimplification – any differences could well be explained by confounders such as gestational age and birthweight (e.g., NEC patients likely to have lower gestational age and weight compared with those with Hirschsprung disease).

Multivariate logistic regression will therefore be performed between each complication and the covariates listed under patient factors, surgical disease factors and operation factors. Coefficients with a p-value of <0.05 will be considered significant, but all will be tabulated.

No comparisons will be made between individual hospitals, states or countries due to small numbers expected at some centres.

Brief summary
Stoma formation in the neonatal period is necessary in many surgical conditions. There remains debate surrounding a number of factors (such as indications, type, timing of closure) and a paucity of quality literature to inform these decisions.
The study aims to give an accurate reflection of practice and outcomes in Australia and New Zealand. Results will be used to aid and improve decision-making for this vulnerable group of patients
