🔍 Key Findings
- Liver masses were most common in the left division (58%), followed by central (27%) and right (15%).
- Right divisional masses were significantly associated with intraoperative complications (33% vs 5.6% left, p = .0037), particularly hemorrhage and injury to major vessels.
- Mortality rate was 6.5% overall, with no significant association with liver lobe location.
- Postoperative complications occurred in 28.7% of cases, but were not significantly associated with mass location.
- Thoracic incision extension (sternotomy or diaphragmotomy) increased odds of postoperative complications by 9.1x (p < .001).
- Use of TA stapler significantly reduced both intraoperative (OR 19x lower) and postoperative complications (OR 4.4x lower) vs other methods.
- Specialist surgeons and heavier dogs had significantly fewer postoperative complications.
- Right lobectomies often required thoracic extension, indirectly linking them to increased postoperative morbidity.
