Other Procedures

Gastrointestinal (GI) endoscopy is a minimally invasive procedure that employs a flexible tube with a camera, known as an endoscope, to visualize the upper or lower gastrointestinal tract. Upper GI endoscopy examines the esophagus, stomach, and part of the small intestine, while lower GI endoscopy—also called a colonoscopy—focuses on the colon and rectum.

How the Procedure Works:

Upper Gastrointestinal Endoscopy (EGD):

1. Preparation: Patients are typically instructed to fast for several hours before the procedure.
2. Sedation: Mild sedation is administered to enhance comfort during the process.
3. Insertion: The endoscope is gently inserted through the mouth and navigated down the esophagus into the stomach.
4. Examination: The doctor inspects the lining of the esophagus, stomach, and the first part of the small intestine for abnormalities. Biopsies or other procedures may be performed if necessary.
5. Completion: The procedure generally lasts about 5-10 minutes. Patients are monitored for a brief period before discharge.

Lower Gastrointestinal Endoscopy (Colonoscopy):

1. Preparation: A thorough bowel preparation is required, often involving dietary restrictions and laxatives to clear the intestines.

2. Sedation: Patients receive sedation to ensure comfort during the procedure.

3. Insertion: The endoscope is inserted into the rectum and advanced through the colon.

4. Examination: The doctor inspects the colon lining for abnormalities, polyps, or signs of disease. Biopsies can also be taken if needed.

5. Completion: The procedure usually takes about 15-20 minutes, and patients are closely monitored afterward.
