Ileostomy

Surgical opening of the ileum through the abdominal wall

Definition

An ileostomy is a surgical opening bringing the end of the ileum (small intestine) to the abdominal surface. It bypasses the entire colon, producing liquid or semi-liquid stool.

Indications

  • Ulcerative colitis or Crohn's disease
  • Colorectal cancer
  • Familial adenomatous polyposis
  • Trauma, bowel perforation

Key Characteristics

Output is LIQUID and contains digestive enzymes that irritate the skin; high fluid and electrolyte loss; no control of output, typically located in the right lower quadrant.

Nursing Care

  • Monitor fluid and electrolyte status closely (especially sodium and potassium)
  • Goal output 500 to 1000 mL/day; greater than 1500 mL = dehydration risk
  • Protect peristomal skin with barrier creams
  • Empty pouch when 1/3 full
  • Teach patients to avoid foods that cause blockage (corn, nuts, popcorn, stringy vegetables)
  • Chew food thoroughly, hydrate well
  • Medications: avoid enteric-coated/extended-release (will not be absorbed)

NCLEX Relevance

Liquid output, high dehydration risk. Skin protection critical.
