Influencing factors of postoperative early delayed gastric emptying after minimally invasive Ivor-Lewis esophagectomy

BACKGROUND The main clinical treatment for esophageal cancer is surgery. Since traditional open esophageal cancer resection has the disadvantages of large trauma, long recovery period, and high postoperative complication rate, its clinical application is gradually reduced. The current report of minimally invasive Ivor-Lewis esophagectomy(MIILE) is increasing. However, researchers found that patients with MIILE had a higher incidence of early delayed gastric emptying(DGE).AIM To investigate the influencing factors of postoperative early DGE after MIILE.METHODS A total of 156 patients diagnosed with esophageal cancer at Deyang People's Hospital were enrolled. According to the criteria of DGE, patients were assigned to a DGE group(n = 49) and a control group(n = 107). The differences between the DGE group and the control group were compared. Multivariate logistic regression analysis was used to further determine the influencing factors of postoperative early DGE. The receiver operating characteristic(ROC) curve was used to assess potential factors in predicting postoperative early DGE.RESULTS Age, intraoperative blood loss, chest drainage time, portion of anxiety score ≥ 45 points, analgesia pump use, postoperative to enteral nutrition interval, and postoperative fluid volume in the DGE group were higher than those in the control group. Perioperative albumin level in the DGE group was lower than that in the control group(P < 0.05). Age, anxiety score, perioperative albumin level,and postoperative fluid volume were independent factors influencing postoperative early DGE, and the differences were statistically significant(P <0.05). The ROC curve analysis revealed that the area under the curve(AUC) foranxiety score was 0.720. The optimum cut-off value was 39, and the sensitivity and specificity were 80.37% and 65.31%, respectively. The AUC for postoperative fluid volume were 0.774. The optimal cut-off value was 1191.86 mL, and the sensitivity and specificity were 65.3% and 77.6%, respectively. The AUC for perioperative albumin level was 0.758. The optimum cut-off value was 26.75 g/L,and the sensitivity and specificity were 97.2% and 46.9%, respectively.CONCLUSION Advanced age, postoperative anxiety, perioperative albumin level, and postoperative fluid volume can increase the incidence of postoperative early DGE.
