Subsequent management

1. The gastric balloon is usually kept inflated for 12-24h and deflated prior to endoscopy ± sclerotherapy. The traction on the tube should be tested hourly by the nursing staff. The oesophageal lumen should be placed on continuous drainage while enteral nutrition and administration of drugs can be given via the gastric lumen.

2. If the oesophageal balloon is used, deflate for 5-10min every 1-2h to reduce the risk of oesophageal pressure necrosis. Do not leave oesophageal balloon inflated for longer than 12h after sclerotherapy.

3. The tube may need to stay in situ for 2-3 days though periods of deflation should then be allowed.
