Resumo

Natural Orifice Transluminal Endoscopic Surgery (NOTES) represents an important evolution in minimally invasive surgery. Beyond the elimination of external scars, NOTES aims to improve postoperative recovery by reducing pain and minimizing immunological and physiological disturbances. Advances in surgical techniques, instrumentation, and surgeon training have expanded minimally invasive treatment options for diseases affecting the thorax, abdomen, and pelvis.
 The objective of this study was to propose and describe a standardized transoral NOTES pathway to the thoracic cavity using non-living canine experimental models. The technique involved the creation of a small paramedian incision adjacent to the lingual frenulum, followed by blunt cervical dissection toward the thorax.

Access to bilateral pulmonary lobes, pericardium, heart, diaphragm, and esophagus was successfully achieved. These findings demonstrate the anatomical feasibility of transoral thoracic access in non-living models. However, additional studies using living experimental models are required to assess potential complications, particularly air leakage and contamination along the created access pathway.
