Advances in Minimally Invasive Esophagectomy-An Overview of Recent Developments and a Novel Classification of Innovations in Treatment of Thoracic Esophageal Cancer.

Minimally invasive esophagectomy (MIE) has become increasingly prominent in the surgical management of esophageal cancer (EC) over the past three decades. The adoption of minimally invasive techniques has significantly enhanced oncologic esophageal surgery by improving safety, achieving oncological radicality, preserving physiological function, and elevating the postoperative quality of life of the patients. The complexity of MIE lies in its technical nuances, which critically influence postoperative morbidity and, in severe cases, mortality, especially when complications evolve unchecked. These risks underscore the importance of meticulous surgical execution and perioperative management. The optimization of mediastinal lymphadenectomy and the reduction of procedure-related morbidity have consistently represented focal points of scientific inquiry and clinical refinement, posing a persistent challenge for esophageal surgeons. MIE is widely regarded as one of the most technically demanding procedures in oncologic surgery. Its advantages, however, are most evident in the postoperative phase, where reduced trauma and faster recovery are key benefits. Experienced surgical teams have introduced refinements to MIE protocols, aiming to optimize precision and reduce complication rates. This study aims to systematically synthesize the main technological advancements and innovations currently employed in the minimally invasive management of EC, presenting them in a structured classification designed to be both accessible and practical for specialists engaged in this domain.
