A “gold standard” randomised controlled trial using Omeprazole drug treatment (vs a placebo) for all OA babies.
Despite the existence of an international guideline (ESPGHAN / NASPGHAN) suggesting Omeprazole treatment, there is no “gold standard” evidence anywhere in the world which shows this is beneficial, and some research which indicates it may well cause problems.
The Feasibility study stage started in Spring 2021, and was completed during 2022. The main phase of the study is expected to be underway during Summer 2025 and run for some 6 years.
Throughout the UK. Many of the specialist NHS centres at which OA babies have surgery have agreed to be involved. The chance to take part is expected to be offered to the parents (who can decline participation) of the majority of OA babies born in the UK.
The study is led by Professor Nigel Hall (Southampton University) and fellow paediatric surgeon Mr Iain Yardley (Evelina Hospital). Oxford University’s National Perinatal Epidemiology Unit is organising much of the detail of the study. The feasibility study has been undertaken by researchers at Liverpool University. Academic staff at Nottingham University are also involved. TOFS is a signatory to the collaboration agreement. The study is funded by the National Institute for Healthcare Research.
TOFS is Patient and Public Participation partner for the study. We have been involved since 2019, and have made numerous suggestions to try to make the detail of the study (and indeed the language describing it) as patient-friendly as possible. About 20 TOFS members took part in detailed interviews as part of the feasibility study, and TOFS members make up the study’s “Parent Advisory Group”.
Within the UK, it is very likely that surgeons will take note of the findings. In the long term, we anticipate that they will either::
It is expected that the trial’s outcomes will be used to bolster the ESPGHAN / NASPGHAN recommendations – or revise them.
The feasibility study and its findings have been described in a 2023 paper in the British Medical Journal, which is accessible by anybody: “Mixed-methods feasibility study to inform a randomised controlled trial of proton pump inhibitors to reduce strictures following neonatal surgery for oesophageal atresia.”
A presentation about TOAST has been given in 2022 to the annual congress of the British Association of Paediatric Surgeons and to the INoEA Worldwide Oesophageal Atresia conference and also to the International Clinical Trials Methodology conference.

Professor Nigel Hall presented at the TOFS seminar in November 2023. Below is a video recording of his presentation.
For a full description of the TOAST study, please see the study’s own website at Oxford University’s NPEU. The information above is deliberately written in a patient-focussed summary form, and inevitably omits much detail.
The latest updates to this project will be shown here as they are published.
