Surgical Staplers Flashcards
You should not use staples in the ______ b/c they would transect all circular muscle fibers
Small colon
High risk of impaction and dehiscence if you use staples at this site
Small colon
Do staples or sutures have higher bursting pressure?
Sutures
2 staggered rows of B-shaped staples to seal tissues and vessels
Thoracoabdominal stapler
Everts the mucosa which could lead to abscessation and more adhesions
TA stapler
Why is oversewing a TA stapled incision not an option?
Abscess formation
Which stapler is better than a TA stapler if there is enough healthy tissue/
Parker-Kerr
Used to close hollow viscera stumps and can be sewn over
Parker-Kerr stapler
What suture pattern do you use over a Parker-Kerr staple line?
Cushing with stapler in place
Lembert after stapler removed
Rank the bursting pressure of handsewn, skin stapler, and TA 90 for closure of a PF enterotomy
HS > skin stapler > TA-90
Rank the cost of handsewn, skin stapler, and TA 90 for closure of a PF enterotomy
TA-90 > skin stapler > HS
What carries a higher risk of abscessation?
Eversion of mucosa
GIA
Gi anastomosis stapler
ILA
Intestinal linear astamosis stapler
What anastamoses are GIA and ILA used for?
Side-to-side
4 staggered rows of B-shaped stables w/cutting blade to divide tissue between 2nd and 3rd rows
GI staplers
When are GIA and ILA (side-to-side) anastamosis techniques used?
Jejunocecostomy or large colon
What kind of anastamosis do we do for small intestine?
End-to-end
What GI stapler is used for laparoscopic procedures?
Endo-GIA
Reduces tissue thickness and makes closure of a GIA staple more effective
Pre-compression
What is GIA pre-compression?
15 sec interval between closing the GIA and firing the staples
What is the more common metal used for staples?
Titanium (also use stainless steel)
What color cartridge is used to indicate large size staples?
Green
What color cartridge is used to indicate small size staples?
Blue
