Ch. 110: Vag/Vest/Vulva

Question 1

Nicoli JSAP 2022

Resection of vaginal septum using endoscopic-guided sealing devices in female dogs: 8 cases (2015-2018)

• devices?
• median resection time?
• complications?

Answer 1

3 used LigaSure, 5 used ENSEAL

Median time of septum resection 100 seconds

No obvious complications

Question 2

Barozzi JSAP 2021

CT characteristics of uterine and vaginal mesenchymal tumors in dogs

• 2 findings more likely malignant?
• conclusion?

Answer 2

Malignant tumors tended to occupy a larger portion of the pelvic canal

Bone involvement only seen w/ malignancy

Conclusion: CT may have limited role in advanced workup of uterine and vaginal mesenchymal tumors

Question 3

Palerme JAVMA 2021

Characterization of recessed vulvas in dogs

• % dx w/ recessed vulva?
• recessed vulva in regards to body weight?
• recessed vulva in regards to neuter status?
• recessed vulva in regards to age of spay?
• recessed vulva in regards to LUT, UTI?

Answer 3

Recessed vulvas were identified in 36 of 250 (14%) dogs.

Dogs with recessed vulvas had significantly higher body condition scores and body weights than unaffected dogs.

Recessed vulvas were more common in spayed than sexually intact dogs.

Dogs spayed at ≤ 1 year of age were almost 3 times as likely to have vulvar recession, compared with dogs spayed at > 1 year of age.

No significant difference was identified between affected and unaffected dogs with respect to the prevalence of LUT signs, urinary tract infections, or perivulvar dermatitis.

Question 4

Ogden Vet Sx 2020 PQ

Outcomes associated with vaginectomy and vulvovaginectomy in 21 dogs

• most common tumors?
• % major complications?
• % post-op urinary incontinence? PQ
• survival times malignant vs. benign PQ

Answer 4

Smooth muscle tumors were diagnosed most commonly (10 leiomyomata, three leiomyosarcomas, two leiomyofibromas)

Major complications requiring revision surgery were recorded in two dogs (10%).

• Postoperative UIC occurred in 29%, resolving spontaneously within 60 days in three dogs *
• Dogs with malignant tumors survived at least 71 days (MST 630 days). Benign tumors, time not reached (survived at least 104 days) *

Question 5

Barrand JSAP 2019

A case of anovaginal cleft in a Chihuahua

• define this cleft
• Px w/ sx?

Answer 5

Congenital incomplete closure of skin fold between anus and dorsal commissure of the vulva

3 cases treated by surgery reconstruction and all made good recoveries – prognosis good
