Exam 2 - Abdominal & Urogenital Sx Flashcards
what are the three approaches to the body wall
ventral midline
paramedian
flank
holding layer of the ventral midline
linea alba
holding layer in the paramedian
external rectus sheath
holding layer in the flank/paralumbar
external abdominal oblique FASCIA
what is the best suture to use for body wall closure
absorbable monofilament
PDS, Maxon, Biosyn, Monocryl, Caprosyn
what suture pattern do you use for body wall closure
appositional - simple continuous (best), simple interrupted, cruciate, near far far near
for body wall closure
____ suture in holding layer
____ suture in the SQ
largest in holding layer
smallest in SQ
what is the holding layer of the intestinal tract
submucosa
what are the healing stages of bowel
- blood clot
- granulation tissue
- blood vessels emerge
- fibrous tissue
when do you need the most suture strength in the bowel?
between 0-7 days
causes of fibrous adhesions
what patterns are more prone?
what species are more prone?
leakage
fecal contamination
exposed suture material
inflamed peritoneal surfaces
everting > appositional > inverting
horses, cattle
what suture should you use on the bowel
monofilament absorbable
what suture pattern should you use on the bowel
appositional - simple continuous or simple interrupted
minimal inverting after appositional in adhesion prone species (horses/cattle) - Cushing, Connell, Lembert, Modified Gambee, Staples
NEVER everting
types of anastomosis
end-end
transverse enterotomy closure
stapled side-side
stapled end-end
end-side
what suture should you use for urogenital surgery
