Equine Approaches to the Abdomen Flashcards
what approaches are done under general anesthesia
- midline
- paramedian
- parainguinal
- laparoscopy
what approaches are done under standing sedation
- flank
- flank laparoscopy
what is the passage through the equine GIT
- small intestine
- cecum
- R ventral colon
- L ventral colon
- pelvic flexure
- L dorsal colon
- R dorsal colon
- transverse colon
- small colon
- rectum
what are indications for abdominal exploration in horses
- colic
- reproductive
what is the normal incision length on ventral midline
25 cm
how much exteriorization is there of the GIT on ventral midline
75% with minimal hemorrhage
cecocolic ligament
lateral band of the cecum
attaches to the R ventral colon
visualizing this ligament signals that the colon is well positioned
ileocecal band
dorsal band of the cecum
attaches to the ileum of the SI
visualizing this ligament signals the end of the SI and start of the colon
what size suture is used in each closure layer for a midline incision
- linea alba: size 3 absorbable monofilament simple continuous
- SQ: size 2-0 absorbable monofilament simple continuous
- appose skin with staples
paramedian approach
8-12 cm incision to the right side of midline
when do you use a paramedian approach
when you want to avoid cutting into a previous midline incision
what is the holding layer in the paramedian approach
external sheath of the rectus abdominis
parainguinal approach
12-14 cm incision located parallel and 2 cm axial to the external inguinal ring
exposes the external oblique aponeurosis
when do you use the parainguinal approach
caudal abdominal surgeries
ex. bladder stones, cryptorchids
why is standing surgery performed
used to avoid general anesthesia in higher risk patients
ovariectomy, cryptorchid, exploratory, etc
