Why dilatation may be considered
A narrowing can contribute to swallowing difficulty, regurgitation or blockage symptoms. The cause and location need evaluation because management differs between inflammation, scarring, motility disorders and other conditions.
Assessment and preparation
Endoscopy, imaging or tissue sampling may be required. Follow individual fasting and medicine instructions, and tell the team about previous surgery, allergies and medicines that affect bleeding.
The procedure
A balloon or dilator may be positioned across the narrowed area under endoscopic guidance. More than one treatment session can sometimes be needed, but the plan depends on the individual.
After dilatation
Follow the diet and observation instructions provided. Seek urgent help for severe chest or abdominal pain, breathing difficulty, fever, vomiting blood, black stools or an inability to swallow.
Questions patients often ask
Will one session always be enough?+
Not always. The response depends on the cause, length and severity of the narrowing.
Is every narrowing suitable for endoscopic dilatation?+
No. The safest approach is selected after assessment and may sometimes involve another treatment.
Can swallowing feel sore afterwards?+
Temporary discomfort can occur, but worsening or severe pain requires prompt medical advice.
