~w/ septic peritonitis 21%

In septic peritonitis dehiscence
~stapled 8%
~Hand-sewn 29%

Risk factors for dehiscence
~septic peritonitis
~Hand‐sewn

Question 2

Rodriguez

Failure:
tearing of suture through tissues

Question 3

Cudney

JAVMA 2021

Answer 3

Difference in AUS & Sx/Necropsy 54%

Sensitivity of AUS
~Spleen 87%
~Liver 37%
~Mesentery 31%

0 of 6 dogs with peritoneal diffuse nodular metastasis had lesions detected by AUS.

Question 4

Hatch

JAVMA 2018

Answer 4

MST 31d
~w/ neoplasia 8d
~w/o neoplasia 73d

Question 5

Guieu
Peripheral and abdominal fluid variable as predictors for post-op septic peritonitis
JAVMA 2016

Answer 5

At 3 days
~Abdominal fluid WBC decreased
~Blood to fluid WBC ratio increased
~Blood to fluid neutrophil ratio increased

Question 6

Fink
Risk factors for recurrent 2ndary septic peritonitis
JVECC 2020

Answer 6

10% developed recurrent 2ndary septic peritonitis
~lower alb prior to 1st surgery
~higher PCV
~GI origin
additional risk in GI origin
~w/ GI FB

Relaporatomy survival 43%

Question 7

Scotti
Prognostic in Cats with septic peritonitis
JVECC 2019

Answer 7

Survival to discharge 70%

Causes
~GI perforation 50%
~Primary septic peritonitis 22%

Appropriate abs 4.4 x more likely to survive

Higher BG = poorer prognosis
(126 vs 164)

Question 8

Indirect vs direct inguinal hernia

Answer 8

Indirect- through the ring, but not vaginal process

Direct- through vaginal process, more likely to strangulate

Question 9

Internal inguinal ring

Answer 9

medially: rectus abdominus m

Cranially: caudal edge of internal abdominal oblique

Laterally and caudally: inguinal ligament

Question 10

External inguinal ring

Answer 10

longitudinal slit in the aponeurosis of external abdominal oblique

Question 11

Autologous Repair of large abdominal wall defects

Answer 11

~Separation of Anatomic Components of the abdominal wall
-Ext oblique release
-Lateral sheath release
~Cranial sartorius m flap
~Ext Abdominal oblique myofascial flap
~Rectus abdominis flap

Answer 13

200 mL/kg

Question 14
