Sandoval et al: Short‐term outcomes of dogs and cats undergoing lung lobectomy using either a self-ligating loop or a thoracoabdominal stapler
Veterinary Surgery 7, 2024

🔍 Key Findings

  • Intra- and postoperative complications occurred only in stapled lobectomies, but the difference was not statistically significant (intra: p = .069, post: p = .112).
  • Intraoperative hemorrhage was the most common complication (11.8%), followed by air leakage (2%).
  • All self-ligating loop (SLL) lobectomies had zero complications (n=18), though the sample was small.
  • Postoperative complications included 4 catastrophic events (cardiopulmonary arrest), all in stapled cases.
  • Lung lobectomy technique was not associated with duration of chest tube use, hospitalization, or survival (p > .05).
  • 94.3% of patients survived to discharge (82/87).
  • SLLs are lower-cost and may be more feasible for thoracoscopic/minimally invasive approaches due to smaller port size (5mm vs. 12mm for staplers).
  • A future superiority study would need ≥103 lobectomies per group to assess differences in complication rates.

Multiple Choice Questions on this study

In Sandoval 2024 et al., on lung lobectomy technique outcomes, how many lobectomies per group are needed for a superiority study comparing SLL and stapler?

A. 58
B. 76
C. 87
D. 103
E. 112

Answer: 103

Explanation: A sample size of 103 per technique group was calculated to power a future superiority trial.
In Sandoval 2024 et al., on lung lobectomy technique outcomes, what was the most common intraoperative complication?

A. Air leakage
B. Stapler misfire
C. Incisional dehiscence
D. Intraoperative hemorrhage
E. Prolonged anesthesia time

Answer: Intraoperative hemorrhage

Explanation: Hemorrhage occurred in 11.8% of lobectomies and was the most frequently observed intraoperative issue.
In Sandoval 2024 et al., on lung lobectomy technique outcomes, what was the survival to discharge rate across all cases?

A. 84.1%
B. 89.2%
C. 91.3%
D. 94.3%
E. 97.9%

Answer: 94.3%

Explanation: A total of 82 out of 87 cases survived to discharge, reflecting a high short-term survival rate.
In Sandoval 2024 et al., on lung lobectomy technique outcomes, which factor was NOT statistically associated with the type of lung lobectomy performed?

A. Survival to discharge
B. Duration of hospitalization
C. Postoperative complications
D. Chest tube duration
E. All of the above

Answer: All of the above

Explanation: None of these outcomes were statistically different between SLL and TA stapler groups (p > .05 for all).
In Sandoval 2024 et al., on lung lobectomy technique outcomes, what percentage of self-ligating loop (SLL) procedures had intra- or postoperative complications?

A. 0%
B. 5%
C. 11%
D. 13.9%
E. 21%

Answer: 0%

Explanation: All intra- and postoperative complications occurred in stapled cases; no SLL complications were reported.
