Jones et al: Comparison of mortality of brachycephalic dogs undergoing partial staphylectomy using conventional incisional, carbon dioxide laser, or bipolar vessel sealing device
Veterinary Surgery 1, 2024

🔍 Key Findings

  • Study compared 606 dogs (English Bulldogs, French Bulldogs, Pugs) undergoing partial staphylectomy via CO₂ laser, bipolar vessel sealing device (BVSD), or conventional incision.
  • Mortality rate: 4.0% (24/606).
  • BVSD was associated with significantly increased perioperative mortality compared to other methods (OR = 6.0, 95% CI: 1.3–28.4, p = .023).
  • High-grade laryngeal collapse (stage II or III) independently increased mortality risk (OR = 4.6, 95% CI: 1.8–11.8, p = .002).
  • No difference in mortality between CO₂ laser and conventional incision techniques.
  • CO₂ laser and conventional techniques had similar complication rates.

Multiple Choice Questions on this study

In Jones 2024 et al., on surgical technique mortality, what was the overall in-hospital mortality rate for dogs undergoing BOAS surgery?

A. 1.2%
B. 2.8%
C. 4.0%
D. 5.7%
E. 7.3%

Answer: 4.0%

Explanation: The study documented a 4.0% in-hospital mortality rate (24/606 dogs).
In Jones 2024 et al., on surgical technique mortality, which factor besides surgical technique was independently associated with increased mortality?

A. Previous BOAS surgery
B. Use of perioperative NSAIDs
C. Invasive non-airway procedures
D. High-grade laryngeal collapse
E. Obesity

Answer: High-grade laryngeal collapse

Explanation: Stage II or III laryngeal collapse had an OR of 4.6 for mortality (p = .002).
In Jones 2024 et al., on surgical technique mortality, what was found when comparing CO₂ laser and conventional incisional techniques?

A. CO₂ laser had significantly lower mortality
B. CO₂ laser had higher complication rates
C. Conventional technique had higher temporary tracheostomy rates
D. No significant difference in mortality
E. Conventional technique had significantly higher mortality

Answer: No significant difference in mortality

Explanation: Mortality rates were statistically equivalent between CO₂ laser and conventional techniques (p = .890).
In Jones 2024 et al., on surgical technique mortality, which technique was associated with the highest perioperative mortality?

A. Conventional incisional technique
B. Carbon dioxide (CO₂) laser technique
C. Bipolar vessel sealing device (BVSD) technique
D. Laser diode technique
E. Harmonic scalpel technique

Answer: Bipolar vessel sealing device (BVSD) technique

Explanation: BVSD was significantly associated with increased mortality risk (OR = 6.0, p = .023).
In Jones 2024 et al., on surgical technique mortality, what possible reason was proposed for increased mortality with BVSD?

A. Inadequate anesthesia time
B. Surgeon inexperience
C. Delayed extubation
D. Thermal injury causing pharyngeal edema
E. Postoperative opioid use

Answer: Thermal injury causing pharyngeal edema

Explanation: Authors hypothesized that thermal injury and edema may contribute to complications.
