n. a surgical operation in which a part of the colon is brought through the abdominal wall and an artificial opening is created in order to drain or decompress the contents of colon. The part of the colon chosen depends on the site of obstruction or disease process. Depending on the indication a colostomy may be temporary, eventually being closed after months or years to restore intestinal continuity; or permanent, when the colon distal to the colostomy has been removed or is diseased. A bag is usually worn over the colostomy opening (stoma) to collect the faeces for disposal.
