Procedures
Esophageal Dialatation
- An upper gastrointestinal (GI) endoscopy is a procedure to look at the inside of the oesophagus (gullet), stomach and duodenum using a flexible telescope. This procedure is sometimes known as a gastroscopy. A dilatation involves stretching the narrowed area. This is done either using ballon dilator, plastic graduated dilators (Gillard Savory dialators) or Bougie dilators.
- If appropriate, the endoscopist may offer you a sedative to help you relax. An upper GI endoscopy usually takes about a quarter of an hour. The procedure involves placing a flexible telescope (endoscope) into the back of your throat. From here the endoscope will pass on into your duodenum. The endoscopist will be able to look for problems in these organs. They will be able to perform biopsies and take photographs to help make the diagnosis. The endoscopist can perform a dilatation using a guidewire and dilators or a balloon dilator.
- Complications that can happen include Allergic reaction, Breathing difficulties or heart irregularities, Making a hole in the oesophagus, stomach or duodenum at the narrowing, damage to teeth or bridgework, Bleeding, Incomplete procedure etc.
- If you were given intravenous sedation, you will normally recover in about an hour. A member of the team will tell you what was found during the endoscopy and will discuss with you any treatment or follow-up you need. You should be able to go back to work one to two days after the endoscopy. An upper GI endoscopy and dilatation is usually a safe and effective way of finding out if you have a problem with the upper part of your digestive system and treating your symptoms.
Patient preparation for the procedure
Preparation for EVL is fasting for 4-6 hours similar to performing a regular esophagogastroduodenoscopy (EGD). An intravenous line is placed to deliver sedation or other medications.
