Q

uncommon spontaneous injuries to cattle, although they occur as
developmental anomalies in cases of anal atresia

A

simple rectovaginal fistulae

25
result from unsuccessful attempted closure of a third-degree perineal tear, as in the mare.
simple rectovaginal fistulae
26
in mares, the initial injury is usually perforation of the vaginal roof by a ___ which may be deflected ___ during the second stage of labour by a hymeneal rim As a result of vigorous sustained straining, the limb is then likely to perforate the rectum and be forced, possibly with the fetal head, through the ____ , which in turn may be ruptured
fetal forelimb dorsally anal orifice
27
e a third-degree defect is easier to repair surgically than a rectovaginal fistula which would otherwise resu t/f
t
28
_____ of the injury may allow repositioning of the fetal extremities and normal vaginal delivery, but deliberate incision of the perineum and anal sphincter is usually expedient if the rectum is perforated
early recognition
29
most common perineal injury in the mare but rectovaginal fistula formation is still more frequent in the mare than the cow
third-degree tears
30
second-degree defects are rare in the ___ but not uncommon in ___, simply because of the different mechanisms of tearing in the two species
mares, cows
31
advisable to stitch deep perineal wounds that have not perforated the anal sphincter as soon as possible t/f
t
32
Third-degree tears with destruction of the sphincter and rectovaginal fistulae should be stitched up as well t/f
f - left to heal by granulation and surgical reconstruction can be undertaken later if necessary
33
The extent of such defects is considerably reduced by
cicatrisation
34
small, oblique fistulae in the mare does not close completely, but in most cases a significant defect remain t/f
f - walang does not
35
The clinical effects of a third-degree defect are two-fold: continuous ____ of air into the vagina and contamination of the vaginal lumen with ____ or, worse still, accumulation of ____ in its terminal segment
aspiration fecal fluids fecal boluses
36
distorting the lumen, may lead to pooling of urine cranial to the external urethral meatus.
pneuomovagina
37
In both species(cow and mare), therefore, sizeable cloacal lesions result in ____and affected mares are also aesthetically unsuited for other uses because of perineal incompetence
infertility
38
The few animals that are able to maintain a normal pregnancy are generally found to have a caudally sited lesion of very long diameter t/f
f - limited diameter
39
Surgical intervention should be delayed until all tissue surfaces are covered by _____ and this usually takes 6 weeks or so
epithelium
40
In the mares, the ____r is sometimes everted soon after the injury occurs , but it is easily replaced and retained if necessary with sutures. There is no need for other treatment during the intervening period except perhaps for_____ prophylaxis in the mare
urinary bladder tetanus
41
Second-degree defects are easily obliterated by stripping the vaginal mucosa from the normal level of the upper vulval commissure dorsally on both sides and suturing the submucosal tissues as in a ___ operation.
caslick
42
For many years, surgical reconstruction of the perineum was based on the technique described by ____ in 1938
Götze
43
stripping of mucosal surface --> residual shelf b/w rectum and vagina fixed ____ --> seperating the two caviies
caudally
44
rectum and vagina are separated by the construction of a new shelf from tissues in situ without undue tension on suture lines. whose technique is this?
Aanes
45
n cattle, the operation is ideally performed under general anesthesia t/f
f - caudal epi only
46
animal in dorsal recumbency and the hindquarters raised, under general anaesth what animal ?
mare
47
Mares require no dietary preparation. In the cow, a laxative diet without roughage is advisable for 3 days beforehand, followed by overnight starvation t/f

vesical catheter
49
in cows 6cm deep from the perineum mares longer than this and sometimes extends to the cervix t/f
t
50
cicatrisation results in considerable ____ of the cloaca which should be corrected before suturing is begun
assymetry
51
The curtain of separated vaginal mucosa is then included in the______ sutures of polyglycolic acid which are placed and tied serially from the depth of the wound outward
purse string
52
The operation is completed with ____sutures in the perineal ski
mattress
52
TUnless the vulval length is inadvertently shortened during reconstruction, subsequent parturition in both the cow and the mare usually occurs ____ without the risk of vulval tearing or the need for episiotomy
normllya
53
y. Paradoxically, a simple rectovaginal fistula is easier to repair than a third-degree defectvt/f
f - fistula mas difficult
54
Unless the fistula is deeply sited, it can be exposed satisfactorily by a dorsal commissure ____ which is extended cranially under the anal sphincter and rectal floor beyond the fistula
episiotomy
55
Aanes (1964) recommends that such lesions should first be converted into a cloaca and repaired as such after granulation stops t/f
t
56
Aanes advocated a one-stage operation, but the method to be described for repair of a thirddegree defect is a two-stage procedure with other minor modifications of his suturing technique t/f
f -2 stage yung kay aanes, one stage yung 3rd degree
57
Perineal defects are usually obvious in cows but are nevertheless sometimes not noticed by unwary purchasers.They are less obvious in mares, particularly if the anal orifice remains intact t/f
