Incidence and risk factors for postsurgical gastroparesis syndrome after laparoscopic and open radical gastrectomy

BACKGROUND The aim of this study was to investigate the differences and influencing factors for postsurgical gastroparesis syndrome incidence after laparoscopic and open radical gastrectomy. METHODS Clinical data were collected for 563 patients who underwent open radical gastrectomy for gastric cancer and 72 cases receiving laparoscopic radical gastrectomy. We retrospectively analyzed the incidence of postsurgical gastroparesis syndrome, clinical features, course of disease, and risk factors of these two groups. RESULTS There was no statistical difference for the incident rate of postsurgical gastroparesis syndrome between laparoscopic and open radical gastrectomy (6.9% vs. 3.7%, P > 0.05). Preoperative outflow tract obstruction and Billroth II anastomosis were the two risk factors for postsurgical gastroparesis syndrome in the open radical gastrectomy group and the laparoscopic surgery for gastric cancer group. The same results were obtained from logistic regression statistical analysis. Age greater than 70 years was also one of the risk factors for postsurgical gastroparesis syndrome in the open radical gastrectomy group (P < 0.05). CONCLUSIONS Laparoscopic radical gastrectomy for gastric cancer does not increase the incident rate of postsurgical gastroparesis syndrome.
