Endoscopy There are many tools for investigating<unk>  problems. The most common is endoscopy. This procedure is performed as an outpatient and utilizes a small flexible camera. The procedure does require intravenous sedation and takes about 30–45 minutes; the endoscope is inserted via the mouth and can visualize the entire swallowing tube,<unk>  and duodenum. The procedure also allows the physician to obtain biopsy samples. In many cases of bleeding, the surgeon can use the endoscope to treat the source of bleeding with laser, clips or other injectable drugs. X rays Other radiological studies frequently used to assess patients with chronic<unk>  problems include a barium swallow, where a dye is consumed and pictures of the esophagus and<unk>  are obtained every few minutes.
