Scott et al: Complications and outcomes of thoracoscopic-assisted lung lobectomy in dogs
Veterinary Surgery 1, 2023

🔍 Key Findings

  • TA lung lobectomy was feasible in dogs ≥3 kg, including those with lesions up to 10 cm.
  • 12 intraoperative complications (40%) occurred, with 6 dogs (20%) converted to open thoracotomy, mainly due to adhesions or inability to isolate lobes.
  • Postoperative complications occurred in 8 dogs (27%), most were mild (63%), and only 1 death (3%) was reported.
  • Median hospitalization was 47 hours; 29/30 dogs were discharged successfully.
  • One-lung ventilation (OLV) was attempted in 7 dogs but successfully maintained in only 4.
  • Linear staplers had shorter surgery times (median 57.5 min) than endoscopic staplers (80 min).
  • Histopathology confirmed neoplasia in 77% of cases, most commonly papillary and bronchioalveolar carcinoma.
  • TA lobectomy allows MIS in smaller dogs or with large lesions, avoiding need for full thoracotomy or complex anesthesia/stapling.

Multiple Choice Questions on this study

In Scott 2023 et al., on thoracoscopic-assisted lung lobectomy, what was the most common **histopathologic diagnosis** among the excised pulmonary lesions?

A. Histiocytic sarcoma
B. Chondrosarcoma
C. Bronchioalveolar carcinoma
D. Papillary pulmonary carcinoma
E. Spindle cell sarcoma

Answer: Papillary pulmonary carcinoma

Explanation: Papillary carcinoma was the most frequent histological diagnosis among dogs undergoing TA lung lobectomy.
In Scott 2023 et al., on thoracoscopic-assisted lung lobectomy, which **surgical device** was associated with **shorter median surgery time**?

A. Endoscopic stapler (EndoGIA)
B. Linear stapler (DST series)
C. Clip applicator
D. Bronchial blocker
E. Wound retraction device

Answer: Linear stapler (DST series)

Explanation: Median surgery time was shorter for procedures using linear staplers (57.5 min) compared to endoscopic staplers (80 min).
In Scott 2023 et al., on thoracoscopic-assisted lung lobectomy, what proportion of dogs **required conversion to open thoracotomy** during surgery?

A. 10%
B. 15%
C. 20%
D. 30%
E. 40%

Answer: 20%

Explanation: Six of thirty dogs (20%) were converted to open thoracotomy due to adhesions, oxygen desaturation, or difficulty isolating the lung lobe.
In Scott 2023 et al., on thoracoscopic-assisted lung lobectomy, what was the **minimum bodyweight** of dogs in which the procedure was successfully performed?

A. 1 kg
B. 2 kg
C. 3 kg
D. 5 kg
E. 7 kg

Answer: 3 kg

Explanation: TA lung lobectomy was successfully performed in dogs as small as 3 kg, expanding MIS feasibility to smaller patients.
In Scott 2023 et al., on thoracoscopic-assisted lung lobectomy, what was the **most common classification** of postoperative complications?

A. Severe
B. Moderate
C. Mild
D. Fatal
E. Unrelated to surgery

Answer: Mild

Explanation: Most postoperative complications (63%) were mild, requiring minimal intervention like aspiration or supportive care.
