Minimally invasive surgery Flashcards
What are minimally invasive surgeries?
surgeries that are less invasive than open s1urgery, same purposes
What are 4 types of minimally invasive surgeries?
- arthroscopic
- laproscopic
- endoscopic
- minimal approach orthopedic surgery
What are the advantages of minimally invasive surgery?
1. less tissue damage 2 .shorter hospital stay 3. minimal post-op pain 4. earlier return to function 5. lower infection risk 6. better quality observation 7. better cosmetics
What are disadvantages of minimally invasive sugery?
- referral hospital only
- equipment expense
- laparoscopic training
- increased operative time (learning curve)
What is arthroscopy used for?
- osteochondral chip fractures
- osteochondrosis
- subchondral bone cysts
- diagnostic exploratory
- assess fracture repair
What are the advantages of laparoscopy?
- observation and access to abdominal organs
- minimal post-op pain
- minimal complications
what do you distend the abdomen with in laparoscopy
CO2–pressures 8-16mmHg
Why is the abdomen inflated with laparoscopy?
- enter abdomen safely
2. allow proper visualization
What are the advantages of standing laparascopy?
surgical acces particularly to dorsal structures
What are the advantages of standing laparascopy?
surgical access particularly to dorsal structures
What is the epiploic foramen?
bordered by liver, pancreas, vena cava portal vein
What position is the horse in for dorsal recumbancy?
trendelenburg position 20-35 degrees down
What are 8 laparoscopic procedures?
- crytorchidectomy
- ovariectomy
- diagnostic laparoscopy
- adhesiolysis
- closure NSS
- inguinal herniohaphy
- colopexy
- cystorrhaphy
What are advantages of the laparoscopic approach? for cryptorchidism
- ease of location of testes
- avoid paramedian or inguinal incisions
- easy return to exercise
What are the two approaches to equine cryptorchidism?
- dorsal recumbancy
2. standing
Which horses are not good candidates for standing laparoscopic cryptorchidectomy?
- foals
miniature horse
horses that are difficult to handle
What are endloop ligatures
used to lasso the testes
What are the advantages of standing laparoscopic ovariectomy
- visibility
- access
- tension free ligation
- secure hemostasis
- avoid general anesthesia
What are methods of hemostasis for ovarioectomy?
- endloop ligature
- roeder knot
- bipolar or monopolar electrosurgical foreps
- vessel-sealing device
- harmonic scalpel
- stapling instrument
- high power ultrasonic shears
8 YAG laser - vascular clips
What are methods of hemostasis for ovarioectomy?
- endloop ligature
- roeder knot
- bipolar or monopolar electrosurgical foreps
- vessel-sealing device
- harmonic scalpel
- stapling instrument
- high power ultrasonic shears
8 YAG laser - vascular clips
What are the advantages of endloops?
- excellent hemostasis
2. cost effective
What are the disadvantages of endloops
- ligature slippage
2. ovarian tumors too large, not adequate hemostasis
When is laparoscopy a useful diagnostic tool?
- recurrent colic
- chronic colic
- persistent weight loss
for biopsy
Why would you close nephrosplenic space?
to prevent left dorsal displacement of large colon–recurrence rate 21%
