Is this trial a fit for you?

Likely a good fit

Children with surgically repaired esophageal atresia who have esophago-esophageal anastomotic strictures requiring endoscopic balloon dilation and who can undergo at least one dilation within a six-month period are ideal candidates.

Probably not a fit

Patients who require endoscopic incisional therapy, have received intralesional steroids within four weeks, have non-esophageal interposition anastomoses, or cannot meet the study's target dilation time or follow-up are unlikely to benefit from this protocol.

What this trial studies

This randomized multi-center trial compares different balloon inflation durations during endoscopic dilation for esophageal anastomotic strictures in children who have had repair of esophageal atresia. Participants at Boston Children's Hospital and Children's Hospital of Philadelphia are assigned to specified inflation times and are followed for outcomes such as need for repeat dilation, symptom relief, and procedural complications over a six-month period. Eligible patients must have esophago-esophageal anastomotic strictures requiring dilation and at least one dilation within a six-month window, while patients needing incisional therapy, recent intralesional steroid, non-esophageal interposition, or who cannot meet target dilation time are excluded. The study tests whether inflation time influences clinical success, safety, and frequency of additional procedures.

Why it matters

Potential benefit: If a particular inflation duration leads to better long-term widening, children may need fewer repeat dilations, less anesthesia exposure, and fewer clinic visits.

How similar studies have gone: Balloon dilation is a standard treatment for strictures and some adult series suggest inflation technique matters, but randomized pediatric data directly comparing inflation durations are lacking.

Inclusion Criteria:

* Diagnosed with esophageal atresia with and without tracheoesophageal fistula, surgically repaired esophageal atresia, esophageal anastomotic strictures requiring endoscopic balloon dilation, and at least 1 endoscopic balloon dilation for esophageal anastomotic strictures within a 6 month period.

Exclusion Criteria:

* Patients who need endoscopic incisional therapy to manage anastomotic stricture during their first follow up endoscopy, patients requiring administration of intralesional steroid within 4 weeks of repair, have no follow up endoscopy within 6 months period, have any anastomosis type other than esophago-esophageal (e.g. jejunal or colonic interposition), and/or failure to meet target dilation time.
