Gastrostomy tube blockage is managed primarily by injecting a small amount of fluid or lubricant to try to ensure that the line is reopened. If necessary, the gastrostomy tube can be replaced. The use of gastrostomy tubes is mainly seen in patients with advanced esophageal cancer, where inability to eat makes it possible to take a gastrostomy to connect the tube to the stomach. Food is then injected through the fistula to ensure that the patient is able to eat. Due to the relatively large diameter of the gastrostomy tube, it is generally not prone to blockage, however, failure to flush the tube after injecting food or slight folding of the tube within the stomach may result in a temporary blockage. The treatment method is generally to use a 20 ml syringe to carefully and slowly inject saline or paraffin oil to reopen the line. During the injection process, care should be taken to be gentle and avoid violence. In addition, if reopening is not possible, replacement of the gastrostomy tube should be considered. It should be noted that after daily injection of food, it is recommended that a small amount of saline be withdrawn and injected, which can flush the food residue in the line into the stomach and reduce the chance of blockage of the line.
