Summary
This study presents a ventral laparoscopic technique for bilateral medial iliac lymph node dissection in dogs under 15kg. This minimally invasive approach allows for efficient bilateral lymph node excision for histopathologic diagnosis.
Area of Science:
- Veterinary Surgery
- Minimally Invasive Techniques
- Canine Oncology
Background:
- Medial iliac lymph nodes (MILNs) are crucial for staging canine cancers.
- Traditional open lymphadenectomy can be invasive.
- Laparoscopic techniques offer potential for less invasive biopsy.
- Accurate sampling of MILNs is vital for diagnosis and treatment planning.
Purpose of the Study:
- To describe and evaluate a ventral laparoscopic technique for bilateral medial iliac lymphadenectomy (MILN) in dogs.
- To assess the feasibility, safety, and efficiency of this minimally invasive surgical approach.
- To determine the suitability of harvested MILN samples for histopathologic diagnosis.
Main Methods:
- A 3-portal ventral laparoscopic approach was employed in 12 research dogs (<15 kg).
- Bilateral MILN dissection was performed using vessel-sealing devices.
- Surgical table tilting facilitated contralateral dissection without repositioning the surgeon.
- Vessel-sealing devices and table tilting were key elements of the technique.
Main Results:
- Bilateral MILNs were successfully identified and excised in all dogs.
- Mean unilateral dissection time was 9.7 min, bilateral 21.0 min, and total surgery 43.7 min.
- Minor complications (hemorrhage, spleen trauma) were managed laparoscopically; no major complications occurred.
- All harvested MILN samples were suitable for histopathologic diagnosis.
Conclusions:
- Ventral laparoscopic bilateral medial iliac lymphadenectomy is a feasible and efficient technique in dogs <15 kg.
- This minimally invasive method provides adequate tissue for histopathologic diagnosis.
- The described technique offers a valuable alternative for excisional biopsy of MILNs.
