Stomas Flashcards
What is a stoma
Surgically created opening on the body between the skin and a hollow viscus
Abdo stomas - divert faeces/urine outside the body
If a stoma was in the Left iliac fossa what would it be
Colostomy
If there was a stoma in the right iliac fossa what could it be for
Ileostomy - bag would have green watery content
Urostomy - bag would have urine in
How can you differentiate between a colostomy and a ileostomy?
a colostomy would have faeces like material in the bag (would be more solid) an ileostomy would have more liquid material and it would be green in colour
A colostomy would be flush to the skin whereas an ileostomy would be spouted as the enzyme are alkali and would irritate the skin
When is a permanent end colostomy put in?
Cases of abdominoperineal resections of large rectal cancers
Removal of entire rectum
When is a temporary end colostomy put in?
performed to allow the bowel to rest in diverticulitis or obstruction due to a tumour
done in a 2 stage Hartmanns procedure - rectum and bowel reanastomosed after
When is a permanent ileostomy put in?
After a panproctocolectomy
for UC or Familial Adematous Polyposis
When is a temporary end ileostomy used?
Used in emergency bowel resection when considered unsafe to form an anastamosis with remaining bowel
When is a urostomy used
After a cystectomy
Located in RIF
Why are loop stomas used
To protect distal anastomoses after surgery
How are loop stomas formed
Loop of bowl is brought to the surface
The bowel is cut and a supporting rod is used to secure the skin
Temporary procedure that can be reversed
What are the complications of a stoma
High output - if consistently >2000ml per day. Causes loss of electrolytes Ischaemia Mucocutaneous separation Skin Irritation Bleeding Ileostomy retraction Small bowel obstruction
