534. EVALUATION OF SURGICAL OUTCOMES IN ROBOTIC-ASSISTED ESOPHAGECTOMY

Abstract Background The adoption of robotic surgery for the treatment of esophageal cancer is on the rise, with reports indicating favorable short-term outcomes. This study aims to evaluate the performance of robotic-assisted esophagectomies at our hospital. Methods We conducted a retrospective analysis of perioperative outcomes in patients who underwent robotic-assisted esophagectomies. Cases requiring a two-stage operation were excluded. Results A total of 64 cases were evaluated, with a median age of 72.0 years (range 46-83). Histological types included SCC/AC/ASC/Other: 49/10/1/4 cases. Clinical stages were 0/I/II/III/IVA/IVB: 1/20/11/27/4/1 cases, respectively. Postoperative complications, classified as Clavien-Dindo (CD) Grade II or higher, occurred in 24 cases (37.5%), which included respiratory complications (pneumonia, atelectasis, pneumothorax) in 7 cases (10.9%), anastomotic leakage in 7 cases (10.9%), recurrent laryngeal nerve palsy in 3 cases (4.7%), anastomotic stricture in 2 cases (3.1%), wound infection in 2 cases, gastric conduit necrosis in 1 case (1.5%), cervical lymphorrhea in 1 case, tracheoesophageal fistula in 1 case, and other complications in 3 cases. Conclusion Robotic-assisted esophagectomies have demonstrated favorable short-term outcomes when compared with prior reports. Further studies are warranted to elucidate the reduction of complications and to determine long-term outcomes.
