Rabbit Surgery Flashcards

Question

Surgical technique difference?

Answer 1

- Vessel in broad ligament which needs ligating - Uterine artery passes along horn and meets with ovarian artery - Make small hole in mesometrium in avascular area and ligate ovarian and uterine artery together in one

Answer 2

- Ligate just caudal to the cervices (far cranial vagina): transfixing or encircling -> ligate more distally risks damage to ureters, bladder vasc & urine leakage - Transect and remove uterus & ovaries

Answer 3

Check stump for bleeding

Answer 4

- Routine abdo closure (scs linea alba, intradermal if poss or skin suture) - AVOID TENSION - 3-0 or 4-0 synthetic absorbable

Answer 5

- ABs not necessary if no complications - Analgesia (NSAID & Opioid) - +/- prokinetics - Nutritional support (syringe feeding asap, monitor eating & faecal output)

Answer 6

Hemorrhage - Leakage of urine into the abdomen - Granuloma/adhesion - Fat necrosis - WOund interference - Gut stasis

Answer 7

- Ligate at level of cervix - Intradermal skin closure with tissue glue - Small suture material - Small suture material - Careful tissue handling - EXcellent post op care

Answer 8

- Hormone-related aggression - Unwanted litters - Reduce unwanted sexual bhvr or sexual frustration - Testicular neoplasia - Testicular torsion

Answer 9

- Once testes decend from around 10 weeks (usually from 5 months) - It is not always necessary to neuter male rabbits (less health benefits as neoplasia and torsion rare)

Answer 10

- Cremaster muscle well developed and readily retract testicles (pressure on inguinal region to get out) - Inguinal ring is open and prone to herniation (always closed castration or close tunic) - Tunica vaginalis firmly attacked to scrotal skin (section attachment with scissors if needed)

Answer 11

Gently incise scrotal sac and vaginal tunic * Gentle pressure to extrude testicle * Incise the tunic * Release the attachment between the scrotal skin and tunica vaginalis to improve exteriorisation * Break down ligament of the head of * epididymis

Answer 12

- Place two clamps over cord - Place two encircling ligatures - Cut between clamps to remove testicles

Answer 13

- Release cord into tunic - Excise some proximal - Liagte tunica vaginalis - Repeat for other testicle

Answer 14

- Incise over scrotal sac - Strip away vaginal tunic from scrotal skin - Break down ligament at caudal tip of testicles

Answer 15

* Place 2 clamps on spermatic cord * One encircling and one transfixing cranial to clamp * Incise between clamps * Check stump for bleeding * Repeat for other testicle

Answer 16

- SKin edges can be opposed (SI suture) or glued * Continue to separate from female for minimum of 6 weeks * Sperm can be stored and survive

Answer 17

* As for OVH * Continue to separate from female for minimum of 6 weeks * Sperm can be stored and survive

Answer 18

* Closed is simple * Tends to be more painful * Higher risk of bleeding from slipped ligatures * Less chance of herniation

Answer 19

* Tend to be same time in length * Less chance of bleeding * Inguinal herniation is rare in rabbits * Easy to accidentally open tunic upon opening

Answer 20

* Even if testicle is abdominal, you can often find caudal end of tunica vaginalis in inguinal canal and gently pull it into inguinal region

Answer 21

Underlying dental disease * Must radiograph * Extract affected teeth if possible * Curette infected bone * Abnormal suppurative reaction ➔thick caseous pus * Fibrous capsule * Culture capsule/not pus * Location can affect prognosis * Care with antibiotic-associated diarrhoea

Answer 22

remove in entirety without breaching capsule

Answer 23

- Surgical excision in total id poss - Exploration and removal of infected tissue (flush and pack) - Marsupialisation - location or size means surgical removal not poss ABS

Answer 24

* Make skin incision. * Blunt dissect skin away from abscess capsule taking care not to penetrate. * Vessels ligated/ cauterised. * Skin closed * Rarely achievable near oral cavity

Answer 25

* Open abscess capsule and suture to surrounding skin * Topical antibacterial preparation is applied which is non toxic if ingested e.g. Manuka honey * Clean with chlorhexidine regularly before applying preparation * Can suture hydrocolloid dressing which can draw pus away whilst protecting wound (Remove in 3-5 days)

Answer 26

- Jaw fracture - Acquired malocclusion - Recurrence or failure to resolve

Answer 27

* Always palpate mandible and maxilla to check for abscesses * Always radiograph – include oblique views * Remove surgically in total where possible * Remove affected teeth/alveolar bone * Always culture (capsule not pus)

Answer 28

* Unique calcium metabolism and high levels of calcium excretion compared to other species * Overweight animals with reduced exercise levels and low water intake are predisposed

Answer 29

- If urethral obstruction attempt to catheterise and flush into bladder and remove via cystotomy - If in bladder remove by cystotomy - If in kidney - don't remove poor rates

Answer 30

Midline incision from umbilicus to pelvis. * Care not to incise bladder when cutting linea alba * Exteriorise Bladder. * Moistened laparotomy swabs are packed around the bladder. * Stay sutures cranial and caudal to planned incision avoiding blood vessels. * Incision in an avascular area on ventral surface.

Answer 31

* Stones may be embedded in bladder wall or may accumulate at bladder neck where they can be easily missed. * Catheter placed through the bladder into urethra to help flush * further calculi out and ensure free flow

Answer 32

* Flush bladder * Closed using one or 2 layer closure, inverting suture pattern * TOP TIPS * Try to avoid suture penetrating full thickness as it can act as a nidus for stone formation. * Can inject saline into bladder to leak test it * Biopsy of the bladder wall can be taken for culture * Routine closure of laparotomy wound.

Answer 33

Abdo palp , CLS, onset of lethargy/weakness/bloating Radiography of gas distended stomach

Answer 34

- Provide analgesia - After radiography need to decide

Answer 35

* Intestinal surgery difficult in rabbit as intestines so thin * Gastrotomy is possible * At ex lap can try and move foreign body to stomach or ileo-colic valve

Answer 36

* Trichobezoars-pellets of impacted hair * Adhesions secondary to previous surgery * Ingestion of other foreign material e.g. carpet

Answer 37

- Fluids - ANalgesia - Prokinetics - Syringe feeding - Pg guarded
