Huerta et al: Leakage pressures of partial and total lung lobectomies performed with thoracoabdominal staplers in cadaveric dogs
Veterinary Surgery 4, 2025

🔍 Key Findings

PL-30 group (partial, TA30-V3 wedge):

  • 100% leaked
  • Median leakage pressure: 10 cm H₂O
  • Most failures from periphery of staple line

PL-60 group (partial, TA60-3.5):

  • 100% leaked
  • Median leakage pressure: 18 cm H₂O
  • Better than PL-30 (p = .006)

TL-30 group (total, TA30-V3):

  • Only 1 of 11 leaked (at 22 cm H₂O)
  • All others resisted pressures >50–65 cm H₂O
  • Significantly higher leakage pressure than both PL groups (p < .001)

Odds ratios (leakage vs TL-30):

  • PL-30: OR 437 at both 20 and 30 cm H₂O (p = .003)
  • PL-60: OR 437 at 20 cm H₂O and 133 at 30 cm H₂O (p = .003)

Recommendation: Prefer TL-30 when possible. If partial needed, PL-60 superior to PL-30, but all partials leaked at physiologic pressures.

Multiple Choice Questions on this study

In Huerta 2025 et al., on leakage in canine lung lobectomy, what was the odds ratio of leakage for PL-30 compared to TL-30 at 30 cm H₂O?

A. 23
B. 65
C. 133
D. 264
E. 437

Answer: 437

Explanation: The odds of leakage for PL-30 vs TL-30 at 30 cm H₂O was 437 (p = .003).
In Huerta 2025 et al., on leakage in canine lung lobectomy, which group had the lowest median leakage pressure?

A. PL-60
B. PL-30
C. TL-30
D. PL-45
E. TL-60

Answer: PL-30

Explanation: The PL-30 group had the lowest median leakage pressure at 10 cm H₂O.
In Huerta 2025 et al., on leakage in canine lung lobectomy, what was the leakage pressure threshold exceeded by most total lobectomy (TL-30) stapled specimens?

A. 18 cm H₂O
B. 22 cm H₂O
C. 30 cm H₂O
D. 40 cm H₂O
E. 50 cm H₂O

Answer: 50 cm H₂O

Explanation: All but one TL-30 sample resisted pressures greater than 50 cm H₂O.
In Huerta 2025 et al., on leakage in canine lung lobectomy, how did PL-60 perform compared to PL-30 in terms of leakage pressure?

A. No difference
B. PL-30 was superior
C. PL-60 had higher pressure resistance
D. PL-60 had higher leak rate
E. PL-60 failed at lower pressure

Answer: PL-60 had higher pressure resistance

Explanation: PL-60 group had significantly higher median leakage pressure than PL-30 (18 vs 10 cm H₂O, p = .006).
In Huerta 2025 et al., on leakage in canine lung lobectomy, what was the most common site of staple line failure in partial lobectomies?

A. Central row
B. Between staples
C. Peripheral edge
D. Staple cartridge seam
E. Stapler misfire zone

Answer: Peripheral edge

Explanation: Most leaks in partial lobectomy specimens occurred at the peripheral edge of the staple line.
