Module 4 - Stomal Therapy Flashcards
Define stoma.
Refers to any surgically constructed opening onto the body surface to facilitate a bodily function.
List reasons for stoma formation/
Malignancy Obstruction Disease process Neurological impairment TraumaTypes
Types of stomas.
Colostomy
Ileostomy
Urostomy (Ileal conduit)
Define colostomy.
A surgical opening into the large intestine with a stoma created on the abdomen
A colostomy can be:
1. Permanent
2. Temporary
Permanent Colostomy - Abdominal-Perineal Resection
- Sigmoid colon, rectum, ischio-rectal tissues and anus removed
- Performed for anal and low rectal cancers
Permanent or Temporary Colostomy - Hartmann’s Procedure
- Abdominal excision of Sigmoid Colon and upper 1/3 of Rectum - Rectal stump oversewn - End colostomy (temporary or permanent) - Performed for disease / trauma / malignancy
Temporary Colostomy - Anterior Resection
- Excision sigmoid colon and rectum with surrounding tissues
- Colostomy (temporary) to protect the anastomosis
- Performed for rectal cancers not invading anal sphincters
Describe Colostomy Appliances
- One-piece Closed or drainable appliances - Two-piece Closed or drainable appliances - Colostomy irrigation No pouch or mini pouch required
Define Ileostomy.
- A surgical opening into the ileum with a stoma created on the abdomen
- Stoma is commonly sited in the terminal ileum
Describe your colon!
- The large intestine (colon) is 1.5 metres long, from caecum to anus
- The rectum is 17cm long
- The anal canal is 3 cm
- The internal anal sphincter is smooth (involuntary) muscle
- The external anal sphincter is striated (voluntary) skeletal muscle
- Slower mass colonic movements in the left / descending colon reduces the frequency and force of faecal expulsion
- Gas and odour are more marked in the right / ascending colon due to bacterial and enzymatic activity
- Prolonged skin contact with effluent is likely to compromise the skin
Describe your ileum!
- The longest part of the small intestine 3.6 metres long
- Provides the most extensive area of digestion and absorption
- Ileal contents (Chyme) are slightly alkaline –pH 7.6
- Prolonged skin contact with effluent is likely to compromise the skin.
Indications for permanent ileostomy.
Crohn’s disease
Ulcerative colitis
Familial Adenomatous
Polyposis
Describe Temporary Loop Ileostomy
- Performed to rest an anastomosis
- To allow a internal reservoir or pouch to heal
- Ileostomy patients need a drainable appliance as the effluent is fluid
Describe a Urostomy or Ileal Conduit. List indications.
An opening into the urinary track with a stoma created on the abdomen.
Indications:
- Malignancy of lower urinary tract
- Intractable interstitial cystitis
- Neurogenic disorders of the bladder
- Trauma to bladder or urethra
- Intractable urinary incontinence
- Problematic suprapubic catheter
- Congenital anomalies
A urostomy or ileal conduit requires a drainable appliance with a non-return value
Pre-operative stoma care.
