Oramas et al: Evaluation of sternal recumbency for laparoscopic right lateral liver lobectomy through a transdiaphragmatic port in a canine cadaveric population
Veterinary Surgery 4, 2025

🔍 Key Findings

  • 13 cadaver dogs underwent laparoscopic right lateral liver lobectomy in sternal recumbency using a transdiaphragmatic intrathoracic trocar (ITT).
  • All lobectomies were successful, regardless of dog size.
  • Median total surgical time: 35.5 min; median lobectomy time: 18.5 min.
  • ITT port enhanced visualization and access to hilus.
  • No correlation between body weight and hilus access (p = .78).
  • Stronger correlation between liver lobe weight and lobectomy time (r = .73, p = .004).
  • Complication in 3/13 cases: Loss of insufflation due to balloon-tip port failure and pneumothorax.
  • Recommendation: Use a new balloon trocar per case in clinical applications to prevent failure.

Multiple Choice Questions on this study

In Oramas 2025 et al., on laparoscopic liver lobectomy, what factor was strongly correlated with increased lobectomy time?

A. Total surgical time
B. Cadaver weight
C. Size of the stapler
D. Distance to hilus
E. Weight of the liver lobe

Answer: Weight of the liver lobe

Explanation: A strong positive correlation was found between lobectomy time and liver lobe weight (r = .73, p = .004).
In Oramas 2025 et al., on laparoscopic liver lobectomy, how many right lateral liver lobectomies were successfully performed?

A. 11
B. 12
C. 13
D. 10
E. 9

Answer: 13

Explanation: All 13 cadavers underwent successful right lateral lobectomy regardless of weight.
In Oramas 2025 et al., on laparoscopic liver lobectomy, what was the main advantage of the intrathoracic transdiaphragmatic trocar (ITT)?

A. Reduced surgical time
B. Increased stapler articulation
C. Improved access and visualization of the hilus
D. Minimized incision size
E. Decreased use of CO2

Answer: Improved access and visualization of the hilus

Explanation: The ITT allowed better access to the hilus for visualization and manipulation during right liver lobectomy.
In Oramas 2025 et al., on laparoscopic liver lobectomy, what was the median total surgical time?

A. 22 minutes
B. 30 minutes
C. 35.5 minutes
D. 40 minutes
E. 50 minutes

Answer: 35.5 minutes

Explanation: Median total surgical time was 35.5 minutes (range 25.1–62.8).
In Oramas 2025 et al., on laparoscopic liver lobectomy, what complication occurred in 3 of 13 cadavers?

A. Stapler jamming
B. Portal vein damage
C. Loss of insufflation due to balloon port failure
D. Gallbladder rupture
E. Hepatic hemorrhage

Answer: Loss of insufflation due to balloon port failure

Explanation: Balloon tip port failure led to loss of pneumoperitoneum and pneumothorax in 3 cases.
