Endoscopic Balloon Dilation for Esophageal Strictures

(BITES Trial)

This trial examines how varying balloon inflation times can aid in treating esophageal strictures in individuals born with esophageal atresia, a condition where the esophagus doesn't develop properly. The treatment uses an endoscopic balloon, a small balloon inserted through a tube, to widen the narrowed esophagus. Participants are divided into two groups: one with a 30-second balloon inflation and another with a 180-second inflation. This trial suits those who have undergone surgery to correct esophageal atresia and required balloon dilation for esophageal strictures in the past six months. As an unphased trial, it provides a unique opportunity to enhance understanding and treatment of esophageal strictures.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Research has shown that endoscopic balloon dilation (EBD) is generally a safe treatment for esophageal narrowing. One study demonstrated a 100% success rate with no unexpected problems. Another study found that using larger balloons is safe and effective, reducing hospital stays and costs.

For children, EBD is also considered safe, though the procedure's success can depend on the practitioner's experience. The risk of complications, such as an esophageal tear, is lower with EBD compared to other methods.

Researchers are excited about endoscopic balloon dilation for esophageal strictures because it offers a non-surgical approach to widening narrowed sections of the esophagus. Unlike traditional methods like surgery or medication, this technique uses a balloon to gently stretch the esophagus, potentially reducing recovery time and discomfort. The trial is exploring two different durations for the dilation, 30 seconds and 180 seconds, to determine the most effective approach. This method could provide a quicker, less invasive option for patients, improving their quality of life with fewer complications.

Research has shown that endoscopic balloon dilation (EBD) can effectively treat esophageal narrowings, with success rates ranging from 66% to 84%. One study demonstrated that weekly EBD led to long-term success for 55% of patients with complex narrowings. Another study found that using EBD as a preventive measure reduced the chance of developing a narrowing from 92% to 59%. However, these narrowings often recur after the first treatment, occurring in about 31.6% of patients. Although EBD generally works well technically, the narrowing might return after treatment. In this trial, participants will be randomized into two groups: Group A will undergo EBD for 30 seconds, and Group B will undergo EBD for 180 seconds, to evaluate the effectiveness of different dilation durations.¹²⁴⁶⁷
