510. INNOVATIVE ROBOTIC-ASSISTED ESOPHAGECTOMY WITH THREE-FIELD LYMPHADENECTOMY: A NOVEL APPROACH TO ESOPHAGEAL CANCER SURGERY

Abstract Background Esophageal squamous cell carcinoma, the predominant form of esophageal cancer in Thailand, often presents at advanced stages (III - IV), necessitating surgical intervention. Radical esophagectomy, including three-field lymphadenectomy, stands as one of the most invasive gastrointestinal surgeries. However, in the era of minimally invasive surgery (MIS), robotic systems have emerged as a formidable approach to achieve radical treatment goals while minimizing surgical invasiveness. This video showcases a novel surgical technique and its challenges. Methods A case of mid-thoracic esophageal squamous cell carcinoma, clinically staged III, treated via robotic-assisted esophagectomy and three-field lymphadenectomy using the Da Vinci Xi system. The operation encompassed three phases: Initially, the thoracic phase with patient in semi-prone position with three robotic and one assistant trocars for complete esophageal mobilization and mediastinal lymph node retrieval. The abdominal phase, followed by the cervical phase, utilized four robotic trocars and one assistant trocar in supine position with hyperextended neck, facilitating perigastric lymph node retrieval, gastric tube reconstruction via the posterior mediastinal route, and cervical esophago-gastric tube anastomosis using a circular stapler. Results The patient experienced an uneventful recovery. Postoperative esophagogastroduodenoscopy on day 1 revealed the integrity of the anastomosis and normal vocal cord function. Imaging conducted on day 7 confirmed that the anastomosis was patent without any leakage. Surgical outcomes included an operative time of 615 minutes, estimated blood loss of 150 ml, a 14-day hospital stay, and recovery without complications. This video highlights the intricacies of the procedure and the robotic system's ability to access anatomically challenging spaces, thereby minimizing surgical invasiveness and enhancing recovery. Conclusion The robotic system is capable of performing radical procedures in anatomically challenging areas, such as narrow spaces and areas requiring precise maneuverability among vital structures. It enables a comprehensive approach spanning from the upper to the lower thoracic regions and diversity of surgery in thoracic and abdominal cavity. Additionally, this presentation highlights unique surgical tips and techniques that enhance the safety and feasibility of robotic-assisted esophagectomy. By significantly reducing surgical errors and optimizing outcomes for both oncologic and minimally invasive surgeries, it thereby marks a significant leap forward in the field of esophageal surgery. https://drive.google.com/file/d/1vrmu2D8TGoetnplcREPWQocXJle4PrOX/view?usp=share_link
