What is an Ostomy?

An ostomy is a surgery performed to redirect stool or urine  out of the body

  • Reasons
    • Rectum/ Colon cancer
    • Intestinal injury
    • Inflammatory bowel disease
    • Obstruction
    • Diverticulitis
  • Through this surgery, part of the intestine is rerouted through the abdominal wall to create a stoma
    • A stoma is a piece  of intestine that protrudes through the abdominal wall and is used to release waste
    • People with an ostomy will wear an ostomy pouch on the stoma to collect intestinal contents
    • Stomas do not have muscles, so intestinal contents pass into the pouch

Types of Ostomies

  • ColostomyDiagram of colostomy in human abdomen; "transverse colon", "descending colon", "ascending colon", "ileum", "end colostomy", "caecum", "sigmoid colon", "rectum", "anus" are labeled
    • Stoma is made from large intestine(colon)
    • May be temporary or permanent
    • May be performed for rectal cancer, diverticulitis, or fecal incontinence

  • Ileostomy
    • Stoma is made from small intestine(ileum)
    • May be temporary or permanent
    • May be used to treat inflammatory bowel disease or rectal cancer


  • UrostomyDiagram of urostomy in human abdomen; "urostomy" and "piece of ileium used to fashion urostomy" labelled.
    • Ureters are redirected to stoma made from small intestine(ileal conduit)
    • Permanent
    • May be used to treat bladder cancer or urinary incontinence

Non-pouch Procedures

  • Ileoanal Reservoir(J Pouch)Diagram indicates that colon has been removed; ileum(labeled) has been stitched near the anus(labeled) to create an ileoanal reservoir(labeled)Colon and rectum are removed
    • Ileum is connected directly to anus, and reservoir collects stool
    • Used to treat polyps in the colon



  • Continent Ileostomy(Kock Pouch)Diagram shows the colon(labeled) and rectum(labeled) have been removed. The ileum(labeled) is connect to an internal kock pouch(labeled) which is directed to an external stoma(labeled)Internal reservoir made in ileum
    • Drained via catheter, no bag necessary
    • Very delicate procedure, not common
    • For candidates who aren’t good candidates for ileoanal reservoir or don’t want a pouch

Pouching Systems

  • Main pieces are the skin barrier and the pouchFront and back view of a white ostomy pouch with a yellow skin barrier.
    • Skin barrier is adhesive portion attached to the skin
      • Protects skin and holds pouch in place
    • Pouch holds waste
      • Pouches for Ileostomies and Colostomies can be drainable(washed and reused, changed every 3-5 days)
      • Pouches for Colostomies can also be closed, meaning they need to be removed and disposed of(changed after every empty)


  • Many other options as wellShows skin barrier being applied by a latex gloved hand to a white abdomen around a bright red stoma
    • Filters-to prevent gas buildup, but without odor
    • Material variety-opaque or transparent/soft covers
    • Closure systems-clamps or integrated closure
      • Urostomy bags have a spout as opposed to a closable mouth
    • Skin barrier-can vary in flexibility, shape, adhesive

TIES® System

  • OstomyCure, a  company based in Oslo, Norway, claims to have a new technology Peach colored cap next to a titanium mesh tube insert that goes inside the stoma.for ileostomates that removes the need for a bag



Ostomate Lifestyle

  • Diet
    • Chew thoroughly
    • Reduce high fiber foods
    • Dehydration is a side effect, so drink regularly
    • May have to avoid foods such as popcorn and nuts
    • Everyone’s body is different
  • 750,000 to 1 million  Americans have an ostomy
  • While ostomates don’t directly qualify for disability benefits,  according to Social Security Administration, conditions such as IBD do qualify
    • Accessible bathrooms
  • United Ostomy Associations of America
