Abstract
Robotic-assisted minimally invasive esophagectomy (RAMIE) has been rapidly spreading worldwide as a novel minimally invasive approach for esophageal cancer. This narrative review aimed to elucidate the current situation and future perspectives of RAMIE for esophageal cancer. References were searched using PubMed and Embase for studies published up to 8 April 2023. Search terms included "esophagectomy" or "esophageal cancer" and "robot" or "robotic" or "robotic-assisted." There are several different uses for the robot in esophagectomy. Overall complications are equivalent or may be less in RAMIE than in open esophagectomy and conventional (thoracoscopic) minimally invasive esophagectomy. Several meta-analyses demonstrated the possibility of RAMIE in reducing pulmonary complications, although the equivalent incidence was observed in two randomized controlled trials. RAMIE may increase the number of dissected lymph nodes, especially in the left recurrent laryngeal nerve area. Long-term outcomes are comparable between the procedures, although further research is required. Further progress in robotic technology combined with artificial intelligence is expected.
