Innovation to Standardization of Thoracolaparoscopic Esophagectomy: Culmination of Three Decades of Experience

Abstract Minimally invasive esophagectomy has seen a great deal of evolution over the last three decades. As one of the earliest adopters of minimally invasive approach for esophagectomy, we present our experience and the lessons we have learnt in over 1300 cases. We adopted the prone position and later modified to mid prone position for the thoracic phase of esophagectomy. This position has several advantages of better exposure due to gravity aided retraction of the lungs, clear operating field as blood trickles away as well as feasibility of rapid conversion to open thoracotomy in emergencies. A major transformation in our surgery was the technical modifications and the extent of mediastinal lymphadenectomy. With refinements in technique and greater understanding of the lymphatic spread, we evolved from standard to extended and even total mediastinal lymphadenectomy improving the oncological outcomes without increasing the operative morbidity. The mean total lymph node yield is over 35. Recurrent laryngeal nerve injury was noted in 7% of cases. The technique of anastomosis was also extensively modified from hand sewn to circular stapler to semi mechanical and finally fully mechanical side to side anastomosis using triangulation technique. The triangulation technique has led to significant reduction in leak rates to less than 5% and stricture formation (1%). Finally, our innovative railroading technique for specimen extraction through the neck is oncologically safe that avoids large incisions in the chest or abdomen. The 30 day mortality rate is less than 1%
