Abstract

Background: Transthoracic esophagectomy for cancer triggers a massive inflammatory reaction. The data whether a minimally invasive esophagectomy (MIE) leads to less pronounced inflammatory response compared to open right-sided transthoracic esophagectomy (OE) are scarce. The aim of this study was to evaluate the extent of the inflammatory reaction, represented by levels of the pro-inflammatory interleukins IL-6 and IL-8, the anti-inflammatory IL-1 RA and the chemokines CINC-1 and MCP-1 in the right pleural fluid and the blood from patients undergoing standard OE or MIE. Methods: Pleural drainage fluid and blood was collected at five different time points during the first 72 h following surgery, and the concentrations of IL-6, IL-8, IL-1 RA, CINC-1 and MCP-1 were analyzed using enzyme-linked immune-sorbent assays in 24 patients undergoing MIE or OE. Results: The groups were matched for cancer stage and comorbidities. Pro- and anti-inflammatory mediator levels in the pleural fluid were markedly increased at the end of surgery and on postoperative days 1–3. The pleural inflammatory response of all cyto- and chemokines was lower in the MIE group, reaching significance at some time points. Cyto- and chemokine response levels measured in the blood were overall lower compared to those in the pleural fluid. The chemokines CINC-1 and MCP-1 reacted less pronounced or not at all. Preoperative pulmonary comorbidity, postoperative pulmonary morbidity and length of surgery were associated with an increased reaction in selected mediators. Conclusions: The minimally invasive technique attenuates the inflammatory response, especially locally in the thoracic compartment. Length of procedure, preoperative pulmonary comorbidity and postoperative pulmonary complications are mirrored in an increase in individual inflammatory markers in the pleural fluid. The value of the chemokines CINC-1 and MCP-1 as markers of inflammation in the setting of esophagectomy is unclear.
