Oesophageal balloon endoscopy is a kind of Oesophageal dilation done to permit the doctor to dilate or stretch any narrowed areas of the oesophagus of the patient. This may be conducted as part of an explorative endoscopy or on its own.

Endoscopy balloon dilators for endoscopy are offered as one time health care gadgets. The dilation of the balloon is performed under fluoroscopic endoscopic guidance of the image. Endoscopic balloon dilators are expanded with water, saline or other fluid materials. Technological development in endoscopy balloon dilators have encouraged accessibility of balloon dilators of various lengths, uses, sizes and designs like multi stage balloon dilators.

Patients should take time to learn about this procedure before being subjected to it, so that they are well prepared for what will happen before, during and after the procedure.

Why Is It Done?

Mostly, this procedure is done because of reflux of stomach acid- related scarring of the oesophagus. This may result in stricture or Oesophageal narrowing. Patients who seek treatment for this condition first experience heart burn as the first sign. Patients with narrowed oesophagus may feel like they have food stuck in the chest causing discomfort, pain or difficulty to swallow.

 Patients may require pre-admission testing, such as barium swallow before procedure, ultrasound, contrast X-ray or a CT scan.


For the procedure, patients may be given general anaesthesia, sedation or local anaesthetics.

A deflated balloon dilator is inserted via the endoscope to the stricture and across it.

When the balloon is inflated, it is shaped like a sausage and it stretches and breaks the stricture. This procedure typically takes half an hour. Patients who stay awake during the procedure may suffer from some discomfort. Doctors can source balloon dilators from multi stage balloon dilator suppliers.
