Background
Esophagectomy is the standard treatment for esophageal cancer, but has a high rate of postoperative complications. Some studies reported the various scoring system to estimate the postoperative complications. However, there were according to various surgical methods and included intra- and post-operative factors. Recently, minimally invasive esophagectomy (MIE) is becoming the first-line treatment for esophageal cancer. The aim of this study was to investigate the risk factors of postoperative complications and to establish a useful system for predicting postoperative complications after transthoracic MIE.
Methods
From 2007 to 2015, 90 patients who underwent transthoracic MIE at our department were enrolled. Patients were divided into two groups according to postoperative complication: patients with major complications (n = 32) and without major complications (n = 58). Major complication was defined as ≥ IIIa in the Clavien–Dindo classification.
Results
Multivariate analysis identified four independent risk factors for predicting postoperative complications: age [≥ 70 years; odd ratio (OR) 6.88; p = 0.001]; sex (male; OR 5.24; p = 0.031); total protein level (< 6.7 mg/dl; OR 6.51; p = 0.002), and C-reactive protein level (≥ 0.15; OR, 6.58; p = 0.001). These four factors were used to establish a score. The complication rate for scores 0–4 were 0, 11, 36, 71, 100%, respectively. The frequency of major complications was significantly associated with the score (p < 0.001). Receiver operator characteristic curves to predict the score with regard to major complications showed an area under the curve value of 0.798 (95% confidence interval: 0.696–0.871, P < 0.001).
Conclusions
Our novel score may help to decide surgical intervention for esophagectomy and provide appropriate resources for perioperative management.
