ABSTRACT
Objective: To develop an endoscopic surgical technique to perform radical lymphadenectomy of the axilla in dogs, aimed at applying it later on to humans.
Setting: Experimental surgery unit, General Hospital of Mexico, Mexico City, Mexico.
Design: Experimental, prospective, descriptive study.
Statistical analysis: Percentages as summary measure for qualitative variables.
Material and methods: We performed tour dissections in two adult mongrel dogs, anesthetized, placed in dorsal decubitus position. The endoscope is introduced under direct vision, to dissect the subcutaneous cellular tissue, CO
2 is insufflated at a 4 mmHg pressure. Once the space is accessed, the axillary structures are dissected and then removed through endoscopy.
Results: Endoscopic access was attained in the four (100%) procedures, being able to remove the ganglionic and connective tissue surrounding the axillary vein, without lesioning vascular or nervous structures. Based on this result, it is possible to propose this approach to the axilla to perform a lymphadenectomy in cases of operable breast cancer, or for conservative treatment, and/or labeling with sentinel ganglion.
Conclusion: The endoscopic approach of the axilla of dogs to remove ganglionic and connective tissue surrounding the axillary vein is feasible, without affecting vascular or nervous structures.
