Stomach disease 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, stomach 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. Other radiological studies frequently used to assess patients with chronic stomach problems include a barium swallow, where a dye is consumed and pictures of the esophagus and stomach are obtained every few minutes.
The Horse's Mouth The Horse's Mouth The Horse's Mouth is a 1944 novel by Anglo-Irish writer Joyce Cary, the third in his "First Trilogy", whose first two books are "Herself Surprised" (1941) and "To Be A Pilgrim" (1942). "The Horse's Mouth" follows the adventures of Gulley Jimson, an artist who would exploit his friends and acquaintances to earn a quid, told from his point of view, just as the other books in the First Trilogy tell events from their central characters' different points of view. Cary's novel also uses Gulley's unique perspective to comment on the social and political events of the time.
