A stent in your esophagus was made fully functional once more.

The oesophagus or gullet connects the mouth with the stomach. It is a muscular tube. The muscles in the oesophagus move food into the stomach. If some disorder has narrowed the oesophagus, it can be kept open using a tube or a stent. This type of stent often consists of a metal mesh. There are stents that unfold, by themselves, in the esophagus.

Over time, a stent can also get constricted itself. For example, this can happen if tissue from the esophagus grows into the metal mesh of the stent. To make the stent fully functional once more, you had a esophageal endoscopy. An esophageal endoscopy involves inserting an examination instrument via the mouth or nose. Such a device may be a flexible or rigid tube. The device is then pushed down into the esophagus. A camera is attached to the tube. This camera then sends images to a screen during the examination. During the esophageal endoscopy a tool can be used to open the stent again.
