THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -You will lie on your left side or your back on an exam table. As the doctor slowly inserts the endoscope, you will feel pressure through your esophagus. The endoscope inflates your stomach by blowing air into it. This gives the doctor a better view of the stomach lining.

Detailed explanation-2: -An upper gastrointestinal endoscopy involves inserting a flexible, lighted tube called an endoscope down your throat and into your esophagus. A tiny camera on the end of the endoscope lets your doctor examine your esophagus, stomach and the beginning of your small intestine, called the duodenum.

Detailed explanation-3: -For esophagogastroduodenoscopy (EGD), patients are typically placed in left lateral decubitus with neck flexed forward. A bite block is placed in the mouth before the endoscope is inserted into the oral cavity.

Detailed explanation-4: -Options range from no anesthesia or sedation at all to general anesthesia, but for upper endoscopies, moderate or deep sedation is most common. The anesthetics that may be used to minimize pain and discomfort and reduce anxiety include propofol, benzodiazepines, and opioids.
