Q

why is large intestinal surgery higher risk than small?

A

increased bacterial load and slower healing time

92
Q

what are the 2 main reasons for large intestinal surgery?

A

intestinal biopsy

colectomy

93
Q

what happens during large intestinal biopsy?

A

partial thickness samples taken with endoscopy (rigid proctoscopy)
full thickness via laparotomy

94
Q

what must you be aware of during full thickness large intestine biopsies?

A

avoid contamination of abdomen with faecal matter

95
Q

what is a colectomy?

A

removal of the colon - high risk

96
Q

when may a colectomy be performed?

A

to treat chronic constipation in cats

97
Q

what are the specific pre-op and inter-op nursing considerations for large intestinal surgery?

A

avoid enemas - intestinal contents is more likely t spill

pre-op antibiotics may be indicated

98
Q

what are the specific post-op nursing considerations for large intestinal surgery?

A

make sure biopsy samples are labelled with site

post-op nutritional support to aid healing

99
Q

what are the main reasons for anal/rectal surgery?

A 
rectal polyps/tumors
rectal prolapse
imperforate anus
anal sac removal
anal furcunculosis
100
Q

what do rectal polyps/tumors cause?

A

straining (tenesmus), bleeding and discomfort

101
Q

how is rectal polyp/tumor surgery performed?

A

rectal pull out where the rectum is everted through the anus to allow removal of polyp
tumor would require larger excision

102
Q

what is rectal prolapse?

A

eversion of the wall of the rectum through the anus, often due to chronic straining (treat primary disease)

103
Q

what can be placed once rectal prolapse is replaced?

A

loose purse string suture around the anus

104
Q

what is imperforate anus?

A

congenital condition where anus doesn’t join with rectum - sometimes be corrected surgically

105
Q

why may anal sacs need removal?

A

chronic sacculitis / impaction / abscessation

106
Q

what dogs is anal furcunculosis seen in?

A

GSDs

107
Q

how is anal furcunculosis treated?

A

immunosuppressive drug therapy mostly - rarely surgery

108
Q

what are the specific pre-op and inter-op nursing considerations for anal/rectal surgery?

A

ask surgeon about preferred positioning
protect prolapse prior to surgery - moist lubricated and no self trauma (buster collar)
peri-anal surgery may need purse string suture

109
Q

what are the specific post-op nursing considerations for anal/rectal surgery?

A

post op nutritional support to aid healing

110
Q

what is the peritoneum?

A

lining of the abdominal cavity

111
Q

what is peritonitis?

A

life threatening infection of the the peritoneum

112
Q

what is peritonitis caused by?

A

if there is contamination or irritation of peritoneum leading to inflammatory response

113
Q

what does peritonitis lead to?

A

severe illness
sepsis
shock
CVS collapse

114
Q

what is the prognosis of peritonitis?

A

guarded

115
Q

what condition should you monitor for following GI surgery?

peritonitis - surgery is a possible cause
