TOAST – helping to improve treatment for babies born with oesophageal atresia

Oesophageal atresia is a rare condition where babies are born without an intact oesophagus (swallowing tube) and usually have a connection between their windpipe and their stomach instead.

Urgent lifesaving surgery is usually done in the first few days of life. The surgery rebuilds the oesophagus. This is usually successful but sometimes there are problems. One of these problems is reflux, where the acid content of the stomach comes back into the oesophagus. Another problem that can happen is that the join, where the oesophagus has been rebuilt, can narrow down (called a stricture) and cause difficulties with feeding and swallowing. It is thought that strictures can be caused or made worse by reflux.

Antacid medication is sometimes used to suppress the acid produced by the stomach and help reduce the risk of strictures. Despite this treatment being used in about half of babies with oesophageal atresia, the evidence for using this medication to reduce the chance of getting a stricture is weak. We don't really know if it works. But we would like to find out because if it does then all babies with oesophageal atresia can be given this treatment and if it does not then we can stop asking parents to give medicine to their baby that has no benefit.

To find out whether or not giving an antacid medication is beneficial to treatment, we are conducting a two phased study. Firstly we conducted a feasibility study and now we are setting up a main trial, where infants with oesophageal atresia will be allocated at random to have an antacid medication or not.

The Feasibility Study

The ideal way to study whether giving antacid medication benefits treatment or not is to conduct a clinical trial; randomly allocating babies to receive antacid medication or not, to see how it affects the likelihood of developing strictures and their severity. However, a clinical trial like this may or may not be acceptable to parents or health professionals. So before we conduct the trial we conducted a feasibility study to understand the views of parents and doctors, in order to find out whether a clinical trial is acceptable to them.

To help us to find out what parents think about the trial and to help design it, we interviewed about 20 parents with infants born with oesophageal atresia, as well as around 50 medical staff in this area. Overall, our findings suggest the trial is acceptable to parents and practitioners, with recommendations for changes to the protocol, information materials and site training package.
