What is a significant complication that may arise from an EGD?

The significant complication that may arise from an esophagogastroduodenoscopy (EGD) is the perforation of the gut. This procedure involves the insertion of a flexible tube with a camera into the esophagus, stomach, and duodenum to visualize the upper gastrointestinal tract. While it is generally safe, there are risks associated with any invasive procedure, particularly those involving the gastrointestinal system.

Perforation can occur when the instruments used during the EGD accidentally puncture the wall of the esophagus, stomach, or duodenum. This is a serious complication because it can lead to leakage of gastrointestinal contents into the abdominal cavity, potentially resulting in peritonitis, sepsis, or other severe infections. These conditions require immediate medical attention and often surgical intervention to repair the perforation and manage any subsequent complications.

In contrast, other options such as severe dehydration, headache, and diplopia do not typically arise directly from an EGD procedure. While dehydration can occur in patients who undergo sedation or if not properly hydrated, it is not a specific complication of the EGD itself. Headaches and diplopia (double vision) are not recognized complications associated with this type of endoscopic examination.
