Flexible endoscopy allows a visual examination of the esophagus, stomach, duodenum and colon. A flexible endoscope consists of of a long, flexible tube with a camera at the end that enters through natural openings allowing examination of the upper and lower gastrointestinal tract. A channel in the endoscope permits various endoscopic tools to be passed for biopsy and retrieval of foreign objects without the need of surgery. Endoscopy decreases pain, decreases the risk of complications, and speeds recovery. Procedures that could be performed include; Esophagoscopy, gastroscopy, duodenoscopy and colonoscopy.
