'''''Ileostomy''''' is a [[stoma (medicine)|stoma]] (surgical opening) constructed by bringing the end or loop of [[small intestine]] (the ''[[ileum]]'') out onto the surface of the skin, or the surgical procedure which creates this opening. Intestinal waste passes out of the ileostomy and is collected in an artificial external [[Ostomy pouching system|pouching system]] which is adhered to the skin. Ileostomies are usually sited above the [[groin]] on the right hand side of the [[abdomen]].▼
▲
Ileostomies are necessary where injury or a surgical response to disease has rendered the [[large intestine]] incapable of safely processing intestinal waste, typically because the [[colon (anatomy)|colon]] and [[rectum]] have been partially or wholly removed.▼
==Uses==
Diseases of the large intestine which may require surgical removal include [[Crohn's disease]], [[ulcerative colitis]], [[familial adenomatous polyposis]], [[constipation]], and total colonic [[Hirschsprung's disease]].<ref name="Guide">[http://www.cancer.org/docroot/CRI/content/CRI_2_6x_Ileostomy.asp ''Ileostomy Guide'']; by the [[American Cancer Society]]; Cancer.org website; retrieved January 2014.</ref> An ileostomy may also be necessary in the treatment of [[colorectal cancer]] or [[ovarian cancer]]. One example is a situation where the cancer [[tumor]] is causing a blockage. In such a case the ileostomy may be temporary, as the common surgical procedure for colorectal cancer is to reconnect the remaining sections of colon or rectum following removal of the tumor provided that enough of the rectum remains intact to preserve [[internal anal sphincter|internal]]/[[external anal sphincter]] function.▼

In a ''temporary'' or ''loop ileostomy'', a loop of the ileum is surgically brought through the skin creating a stoma, but keeping the lower portion of the ileum for future reattachment in cases where the entire colon and rectum are not removed but need time to heal. Temporary ileostomies are also often made as the first stage in surgical construction of an [[ileo-anal pouch]], so [[fecal]] material doesn't enter the newly made pouch until it heals and has been tested for leaks—usually requiring a period of eight to ten weeks. When healing is complete the temporary ileostomy is then "taken down" (or reversed) by surgically repairing the loop of intestine which made the temporary stoma and closing the skin incision.▼
In an ''end ileostomy'', the end of the ileum is everted (turned inside out) to create a spout and the edges are sutured under the skin to anchor the ileum in place. Permanent ileostomies are usually done this way. An end ileostomy may be temporary, notably if some of the large intestine was removed and the bowel or overall health is not considered amenable to tolerating further surgery, such as an [[anastomosis]] to rejoin the small and large intestines.

People with ileostomies must use an ''[[Ostomy pouching system|ostomy pouch]]'' to collect intestinal waste. People with ileostomies typically use an open-ended (referred to as a "drainable") one- or two-piece pouch that is secured at the lower end with a leakproof clip, or velcro fastener. The alternative is the closed-end pouch that must be thrown away when full. Ordinarily, the pouch must be emptied
Ostomy pouches fit close to the body and are usually not visible under regular clothing unless the pouch becomes too full. It is necessary to measure the stoma regularly as it changes shape after the initial surgery. The stomal- or colorectal-nurse does this initially for a patient and advises them on the exact size required for the pouch's opening.

Since the late 1970s, an increasingly popular alternative to an ileostomy has been the ''Barnett continent intestinal reservoir'' (or BCIR). The formation of this pouch (made possible through a procedure first pioneered by
=== Barnett continent intestinal reservoir ===
The Barnett continent intestinal reservoir (BCIR) is a type of an appliance-free intestinal [[ostomy]]. The BCIR was a modified [[Kock pouch]] procedure pioneered by William O. Barnett. It is a surgically created pouch, or reservoir, on the inside of the [[abdomen]], made from the last part of the [[small intestine]] (the [[ileum]]),<ref name="Reference 13" /> and is used for the storage of intestinal [[
====How it works====
The pouch works by storing the liquid waste, which is drained several times a day using a small silicone tube called a [[catheter]]. The catheter is inserted through the surgically created opening on the abdomen into the pouch called a [[Stoma (medicine)|stoma]]. The capacity of the internal pouch increases steadily after surgery: from
The opening through which the catheter is introduced into the pouch is called the [[Stoma (medicine)|stoma]]. It is a small, flat, button-hole opening on the abdomen. Most patients cover the stoma site with a small pad or bandage to absorb the [[mucus]] that accumulates at the opening.<ref name="Reference 6" /><ref group=Note name=Note02/> This mucus formation is natural, and makes insertion of the catheter easier. The BCIR requires no external appliance and it can be drained whenever it is convenient. Most people report draining the pouch 2–4 times a day, and most times they sleep through the night. This can vary depending on what kinds and quantities of food eaten. The process of draining the pouch is simple and quickly mastered. The stoma has no nerve endings, and inserting the catheter is not painful. The process of inserting the catheter and draining the pouch is called ''[[intubation]]'' and takes just a few minutes.

====Surgical candidates====
Line 59 ⟶ 65:
Candidates for BCIR include: people who are dissatisfied with the results of an alternate procedure (whether a conventional Brooke ileostomy or another procedure); patients with a malfunctioning/failed Kock pouch or [[Ileo-anal pouch|IPAA/J-pouch]]; and individuals with poor [[internal anal sphincter|internal]]/[[external anal sphincter]] control who either elect not to have the J-pouch (IPAA) or are not a good candidate for IPAA.<ref name="Reference 1" />
There are, however, some contraindications for having the BCIR surgery. BCIR is not for people who have or need a [[colostomy]], people with [active] [[Crohn's disease]], mesenteric
When Crohn's disease only affects the colon, it may, in select cases, be appropriate to perform a BCIR as an alternative to a conventional ileostomy. If the small intestine is affected, however, it is not safe to have the BCIR (because the internal pouch is created out of the small intestine, which must be healthy).

;ASCRS special study, 1999
In 1999, American Society of Colon and Rectal Surgeons published a unique study on 42 patients with a failed [[Ileo-anal pouch|IPAA/J-pouch]] who converted to the Barnett modification of the Kock pouch (BCIR). The authors noted that their study was significant in the very large number of patients,<ref name="Reference 3" /> approximately 6 times more than studied by any previous author.<ref name="Reference 4" /> The study was published in ''Diseases of the Colon and Rectum'' in April 1999.<ref name="Reference 4" /> The study found:
:* that forty (95.2%) patients of the failed [[Ileo-anal pouch|IPAA]] population reported fully functioning pouches;
:* that two pouches had been excised, one after development of a pouch vesical fistula, the other after emergence of [[Crohn's disease]], which had not been diagnosed at the time of the original [[colectomy]];
Line 85 ⟶ 91:
The study concluded: "The continent ileostomy offers an alternative with a high degree of patient satisfaction, to those patients who face the loss of an [[Ileo-anal pouch|IPAA]]."<ref name="Reference 4" />
