Abstract
BACKGROUND
Esophageal cancer surgery is technically highly demanding. During the past decade robot-assisted surgery has successfully been introduced in esophageal cancer treatment. Various techniques are being evaluated in different centers. In particular, advantages and disadvantages of continuously sutured (COSU) or linear-stapled (LIST) gastroesophageal anastomoses are debated. Here, we comparatively analyzed perioperative morbidities and short-term outcomes in patients undergoing hybrid robot-assisted esophageal surgery following neoadjuvant chemoradiotherapy (nCRT), with COSU or LIST anastomoses in a single center.
METHODS
Following standardized, effective, nCRT, 53 patients underwent a hybrid Ivor Lewis robot-assisted esophagectomy with COSU (n = 32) or LIST (n = 21) gastroesophageal anastomoses. Study endpoints were intra- and postoperative complications, in-hospital morbidity and mortality. Duration of operation, intensive care unit (ICU) and overall hospital stay were also evaluated. Furthermore, rates of rehospitalization, endoscopies, anastomotic stenosis and recurrence were assessed in a 90-day follow-up.
RESULTS
Demographics, ASA scores and tumor characteristics were comparable in the two groups. Median duration of operation was similar in patients with COSU and LIST anastomosis (467 vs. 453 min, IQR 420-521 vs. 416-469, p = 0.0611). Major complications were observed in 4/32 (12.5%) and 4/21 (19%) patients with COSU or LIST anastomosis, respectively (p = 0.697). Anastomotic leakage was observed in 3/32 (9.3%) and 2/21 (9.5%) (p = 1.0) patients with COSU or LIST anastomosis, respectively. Pleural empyema occurred in 1/32 (3.1%) and 2/21 (9.5%) (p = 0.555) patients, respectively. Mortality was similar in the two groups (1/32, 3.1% and 1/21, 4.7%, p = 1.0). Median ICU stay did not differ in patients with COSU or LIST anastomosis (p = 0.255), whereas a slightly, but significantly (p = 0.0393) shorter overall hospital stay was observed for COSU, as compared to LIST cohort (median: 20 vs. 21 days, IQR 17-22 vs. 18-28).
CONCLUSIONS
COSU is not inferior to LIST in the performance of gastroesophageal anastomosis in hybrid Ivor Lewis operations following nCRT.
