Perioperative outcomes of 65 dogs and 15 cats undergoing lung lobectomies with a hilar circumferential ligature
🔍 Key Findings
- Hilar circumferential ligature (HCL) techniques resulted in a low overall complication rate during total lung lobectomy in dogs and cats undergoing surgery for clinical disease.
- 80 animals (65 dogs, 15 cats) underwent removal of 94 lung lobes, with 59 lobectomies performed using a commercial pre-tied ligature loop (CPLL) and 35 using hand-tied circumferential ligatures (HTCL).
- Intraoperative hemorrhage occurred in 4.3% of lobectomies (4/94) and was not significantly associated with ligature type (CPLL vs HTCL), knot type, or number of sutures per pedicle.
- Sliding knots had a notably higher hemorrhage proportion (28.6%), suggesting potential safety concerns with this knot configuration.
- Modified Miller’s knots (n=25) and Roeder knots (n=3) performed without reported hemorrhage complications, supporting their use in hilar ligation.
- One intraoperative mortality occurred due to tumor extrusion into the bronchus, rather than failure of the ligation technique.
- One postoperative complication required revision surgery for pneumothorax 8 days after surgery, indicating a low postoperative complication incidence.
- The technique offers a cost-effective and technically straightforward alternative to stapling devices, supporting broader clinical use of hilar ligature approaches.
