Use of the Endo GIA™ stapler for lung lobectomy in dogs and cats undergoing open thoracic procedures (intercostal, transdiaphragmatic thoracotomy or median sternotomy): A retrospective study of 46 lung lobectomies

🔍 Key Findings

  • Endo GIA staplers were successfully used in 46 lung lobectomies across 37 cases, including 33 dogs and 4 cats, representing the first in vivo clinical report of this stapler for open thoracic lung lobectomy.
  • Most procedures had no intraoperative complications (82.6%), while minor complications occurred in 17.4%, primarily mild hemorrhage or air leakage.
  • No major intraoperative complications were reported, and postoperative catastrophic events occurred in 4/37 cases (10.8%), likely related to underlying comorbidities rather than stapler failure.
  • Short-term outcomes were excellent, with 97% of cases completing 14-day follow-up without complications aside from one seroma.
  • Common indications for lung lobectomy included pulmonary masses, pulmonary bullae, abscess/granuloma, lung lobe torsion, trauma, and spontaneous pneumothorax.
  • Endo GIA staplers provide simultaneous stapling and cutting, with articulation and 360° axial rotation, improving maneuverability in confined thoracic cavities.
  • Tri-Staple technology deploys three staggered staple rows, which may improve sealing, reduce air leakage, and maintain tissue perfusion at the staple line.
  • Overall complication rates were low, supporting the Endo GIA stapler as a safe alternative to traditional TA staplers for open lung lobectomy procedures.

Multiple Choice Questions on this study

In Weaver 2026 et al., on Endo GIA stapler outcomes, what proportion of lung lobectomies had no intraoperative complications?

A. 52%
B. 65%
C. 82.6%
D. 91%
E. 100%

Answer: 82.6%

Explanation: Most procedures were uncomplicated intraoperatively, with 38 of 46 lobectomies (82.6%) having no complications.
In Weaver 2026 et al., on Endo GIA stapler outcomes, what short-term outcome was observed among cases that completed the 14-day follow-up period?

A. High rates of pneumothorax recurrence
B. Major complications in most cases
C. 97% had no postoperative complications
D. 50% required revision surgery
E. Most developed pulmonary hypertension

Answer: 97% had no postoperative complications

Explanation: Among cases with 14-day follow-up, 32 of 33 had no postoperative complications, demonstrating excellent short-term outcomes.
In Weaver 2026 et al., on Endo GIA stapler outcomes, which feature of the Endo GIA stapler distinguishes it from traditional TA staplers during lung lobectomy?

A. Manual tissue transection after firing
B. A fixed non-articulating anvil
C. Simultaneous staple and cut function with articulation and rotation
D. Use only in thoracoscopic procedures
E. Only two staple rows per firing

Answer: Simultaneous staple and cut function with articulation and rotation

Explanation: The Endo GIA stapler provides articulation, axial rotation, and simultaneous staple/cut deployment, improving maneuverability in thoracic cavities.
In Weaver 2026 et al., on Endo GIA stapler outcomes, what was the reported rate of catastrophic postoperative complications?

A. 2.1%
B. 5.8%
C. 8.7%
D. 10.8%
E. 17.4%

Answer: 10.8%

Explanation: Four of 37 cases (10.8%) experienced catastrophic postoperative complications, likely related to comorbidities rather than the stapling technique.
In Weaver 2026 et al., on Endo GIA stapler outcomes, what was the most common indication for lung lobectomy in the study population?

A. Pulmonary mass
B. Lung lobe torsion
C. Pyothorax
D. Penetrating trauma
E. Iatrogenic laceration

Answer: Pulmonary mass

Explanation: Pulmonary masses were the most common indication (15 procedures), followed by pulmonary bullae and abscesses/granulomas.
