When treating gallstones, EHL can be used in conjunction with a spyglass camera, [5] a camera inserted through the throat and esophagus and down into the stomach and duodenum to visualize the bile or pancreatic duct.
The endoscope is gradually advanced down the esophagus making note of any pathology. Excessive insufflation of the stomach is avoided at this stage. The endoscope is quickly passed through the stomach and through the pylorus to examine the first and second parts of the duodenum.

Usually a local anesthetic spray (e.g., lidocaine, benzocaine, xylocaine) is used for the back of the throat or as a jelly/lubricant anesthetic for the esophagus. Sedation and anesthesia are required to make the procedure tolerable and safer, as biting the probe, coughing, vomiting, and patient movement would drastically reduce the value of the ...

Occasionally the patient is left with a mild sore throat, which may respond to saline gargles, or chamomile tea. It may last for weeks or not happen at all.

During the procedure, the person will stand or sit in front ...
