Encyclopedia > Stoma (medicine)

In medicine, a stoma (Greek - plr. stomata) is an opening, usually an unnatural or surgically created opening which connects a portion of the body cavity to the outside environment. Surgical procedures in which stomata are created are ended in the suffix '-ostomy' and begun with a prefix denoting the organ or area being operated on. This article is about the field and science of medical practice and health care. ... A cardiothoracic surgeon performs a mitral valve replacement at the Fitzsimons Army Medical Center. ...


One well-known form of a stoma is a colostomy, which is a surgically-created opening in the large intestine that allows the removal of feces out of the body, bypassing the rectum, to drain into a bag or other collection device. The historical practice of trepanation was also a type of stoma. A colostomy is a surgical procedure that involves connecting a part of the colon onto the anterior abdominal wall, leaving the patient with an opening on the abdomen called a stoma. ... The large intestine, or colon is the last part of digestive system: the final stage of the alimentary canal in vertebrate animals. ... Feces, faeces, or fæces (see spelling differences) is waste product from an animals digestive tract expelled through the anus (or cloaca) during defecation. ... The rectum (from the Latin rectum intestinum, meaning straight intestine) is the final straight portion of the large intestine in some mammals, and the gut in others, terminating in the anus. ... 18th century French illustration of trepanation Trepanation (also known as trepanning, trephination, trephining or burr hole) is a form of surgery in which a hole is drilled or scraped into the skull, thus exposing the dura mater in order to treat health problems related to intracranial diseases, though in the...



ADDITIONAL Stoma (Anatomy), a Stoma refers to a mouthlike part. In particular it relates to a procedure involving the G.I.S. (Gastro Intestinal System) which is constituted of the Gastrointestinal Tract (G.I.T.). The G.I.T. begins at the mouth or oral cavity and continues until its termination, which is the anus. This surgical procedure is invoked usually as a result of and solution to disease in the G.I.T. The procedure involves bisecting this tube, usually between the later stage of the small intestine (Ileum) and the Large Intestine or Colon, hence Colostomy, and exiting it from the body in the abdominal region. The point of exiting is what is known as the Stoma. For greatest success and to minimise mal effect it is preferable to perform this procedure as low down in the tract as possible as this allows the optimal amount of natural digestion to occur before eliminating faecal matter from the body. The Stoma usually will have a purpose built removable bag attached to allow the containment and controlled disposal of the waste produced. The gastrointestinal tract or digestive tract, also referred to as the GI tract or the alimentary canal, (nourishment canal) or the gut, is the system of organs within multicellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste. ...

Abdominal Surgery: Summary Procedure and Principles (5448 words)
The stoma is wider than the intact bowel as a result of the anastomotic technique recommended.
The stoma is placed parallel to and between the medial and dorsal (white arrowhead) bands of the cecum and as much of the cecum as possible is exteriorized to place the anastomosis high on the cecal body, in this case almost level with the attachment of the cecocolic fold (arrow) to the right ventral colon.
Failure to do this will place the stoma too close to the mesentery and to the dorsal band of the cecum, and will rotate the jejunum so that it is kinked at the anastomosis.
