Purpose
Delayed gastric emptying (DGE) is associated with prolonged hospital stay and higher healthcare costs. This study aimed to investigate the risk factors for DGE after D3 radical resection for colon cancer and to build a nomogram for this complication.
Methods
We analyzed, retrospectively, 1160 consecutive patients who underwent surgery with D3 lymphadenectomy for colon cancer between January, 2012 and June, 2018. A multivariate logistic regression analysis was used to identify the risk factors for DGE and to build a DGE nomogram model.
Results
There were ten, six and four patients with DGE classified as grades A, B and C, respectively, representing a DGE rate of 1.7%. Multivariate analysis revealed that age (P = 0.001), dissection of the gastrocolic ligament lymph nodes (GCLNs) (P = 0.001), surgical duration (P = 0.017) and preoperative hemoglobin level (P = 0.016) were independent risk factors, and were included to build a predictive model for DGE. The therapeutic index of GCLN dissection was approximately half that of D3 lymphadenectomy (2.9 vs. 5.6).
Conclusions
DGE is more likely to develop in patients aged > 75 years, those with a preoperative hemoglobin < 90 g/L, those with a surgical duration > 210 min, and those who undergo GCLN dissection. The nomogram may facilitate the stratification of patients at risk for DGE following D3 lymphadenectomy for colon cancer. Assessing long-term outcomes will help to evaluate the survival benefit of GCLN dissection in the future, to avoid unnecessary dissection and reduce the incidence of DGE.
