Q

margins for tumors of maxilla / mandible?

A

○ at least 2 cm (preferably 3 cm) are recommended for malignant cancers (SCC, malignant melanoma, fibrosarcoma) in the dog.
○ If possible, mandibular SCC in the cat should be treated with surgical margins greater than 2 cm because of high local recurrence rates (Northrup et al. 2006).
○ If 3 cm margins are not possible without significant risk of morbidity, 1 cm margins of normal tissue beyond either the grossly visible tumor or the extent of the tumor as determined by imaging, whichever is greater, may be acceptable for malignant oral tumors and 0.5 cm margins for benign tumors (Syrcle et al. 2008).

Q

sx considerations for maxi/mandibulectomy / sx planning

A
  • minimum margins include:
    ○ 3 cm of bone rostral and caudal to the tumor, based on either gross palpation or preferably imaging findings
    ○ 1 cm of soft tissue (buccal, gingival, or palatine mucosa).
    • if there is no evidence of rostral mandibular tumors crossing the mandibular symphysis, then excision of the symphysis, including the contralateral middle incisor, should be sufficient
    • Osteotomies bw teeth
    • Closure: monofil abs, PDS recc

o support the implementation of NIRF as an adjunct to gross examination of the gastric wall in dogs with GDV

likelihood of postop septic peritonitis/mortality ?

A

< 5.2%

Q
  • Hiebert et al, JFMS 2022. Intestinal dehiscence and mortality in cats undergoing gastrointestinal surgery

mortality rate? odds of death w/ preop septic abd? dehiscence?

A

o 18% mortality rate – inc mortality d/t preop septic abdomen, hypothermia
o Cats w/ preop septic abd had 6.7x higher odds of mortality
o GI dehiscence = <1%

Q
  • Mullen et al, JAVMA 2021. Evaluation of intraoperative leak testing of small intestinal anastomoses performed by hand-sewn and stapled techniques in dogs: 131 cases (2008–2019)

dehiscence for feesa vs handsew?
relationship w leak testing?

A

o Dehiscence rate =9% – 10% FEESA vs 6% handsew
o Performing leak testing was not assoc w/ dec incidence of dehiscence
o No dehiscence in any R&As w/ positive leak test + augmentation vs 8.8% of R&As with neg leak test

81
Q
  • Anderson et al. JSAP 2021. Outcome following surgery to treat septic peritonitis in 95 cats in the UK.
    survival rate? was px worse if pre-op peritonitis
A

o survival rate = 66%
o Cats with GI dehiscence did not have a worse px
o Intraop hypotension assoc w/ death

82
Q
  • Tidd, VS 2019. Outcomes in 40 cats with discrete intermediate- or large-cell gastrointestinal lymphoma masses treated with surgical mass resection (2005-2015).

MST for LI vs SI?
what was associated with w/ survival

A

MST: large intestine MST = 675d (~2y)&raquo_space;> gastric MST = 96d (3mo) > SI MST = 65d (2mo)
o Complete margins assoc w/ survival: complete = 370d vs dirty = 83d

83
Q
  • DePompeo, JAVMA 2018. Intra-abdominal complications following intestinal anastomoses by suture or staple techniques in dogs

dehiscence rates for handsew vs stapled?
recc if preop septic peritonitis?

A

Dehiscence rates: handsew=13% vs stapled =5%
o dogs with preop septic peritonitis– subsequent dehiscence in 60% handsew vs 0% stapled
 recc stapled anastomosis if preop septic peritonitis

84
Q
  • Grimes, JAVMA 2011. Identification of risk factors for septic peritonitis and failure to survive following gastrointestinal surgery in dogs

risk factors for dehiscence? what was protective factor?
if preop peritonitis–> % w/ continued peritonitis postoperative?

A

Risk factors for dehiscence: preoperative septic peritonitis, low preop albumin & TP, and intraop hypotension
o Presence of a foreign body was a protective factor
o Dehiscence rates: 6% without preop peritonitis vs 20% with peritonitis –30% of dogs w/ peritonitis continued to have peritonitis
