Endoscopy
Endoscopy is a procedure that utilizes a tiny tubular instrument (called an endoscope) with a video camera at the end. Endoscopy can be performed on the gastrointestinal tract (esophagus, stomach, small intestine, and colon), the urinary tract, the nasal cavity, or the respiratory tract. During the procedure, biopsy samples and cultures can be obtained if needed. Endoscopy does require general anesthesia to minimize discomfort.
