Abstract

Background

The aim of the study was to assess serum C-reactive protein (CRP) level immediately after minimally invasive esophagectomy (MIE) as a surrogate of surgical invasiveness in patients who underwent esophagectomy.

Methods

In total, 104 patients were enrolled in the study: 37 patients underwent MIE in the left lateral decubitus position (MIE-LP) and 67 patients underwent MIE in the prone position (MIE-PP). Serum CRP levels were assessed on POD 1, 3, 5, and 7 after MIE, and were compared with surgical outcomes and duration of systemic inflammatory response syndrome (SIRS) to investigate less invasiveness of the MIE.

Results

Reduced serum CRP level on POD 1 was associated with PP during MIE (P < 0.001) and decreased blood loss (P = 0.03). MIE-PP was identified as a significant independent predictor of reduced CRP level on POD 1 (odds ratio 3.65, P = 0.042). CRP level on POD 7 was associated with gender (P = 0.02), position of MIE (P = 0.011), blood loss (P = 0.02), and respiratory complications and/or anastomotic leakage (P < 0.001). Postoperative respiratory and/or anastomotic complication was identified as a significant predictor of elevated serum CRP level on POD 7 (odds ratio 3.44, P = 0.048). Shorter duration of SIRS was shown in the patients with reduced serum CRP level on POD 1 and 7 (P = 0.03 and P < 0.001, respectively).

Conclusion

Serial assessments of serum CRP level immediately after MIE may be a possible indicator that can reflect surgical invasiveness and postoperative complications.
