Abstract

Background: Pylorus-preserving gastrectomy (PPG) has the postoperative advantages of a better quality of life and less weight loss than distal gastrectomy. However, postoperative delayed gastric emptying (DGE) due to antral hypomotility can be a problem. Although preserving the infra-pyloric vein (IPV) is reported to improve congestion of the antrum and prevent DGE, the benefits of this procedure have not been confirmed. The present study aimed to clarify the preventive effect on DGE of preserving the IPV. Methods: A total of 148 patients [IPV-preserved (IPVP): 78 patients and IPV-non-preserved (IPVN): 70 patients] who underwent laparoscopic and robotic PPG (LRPPG) for early gastric cancer were enrolled in this study. The clinicopathologic characteristics and incidence of DGE were compared between the groups. The nutritional risk index (NRI) at 1, 2, and 3 years after the operation and the relapse-free survival (RFS) were also compared. Results: There were no significant differences in the clinicopathological characteristics between the two groups. DGE was observed in 15 of 148 patients (10.1%). The incidence of DGE did not differ markedly between the 2 groups (IPVP vs. IPVN; 11.5% vs. 8.6% p = 0.596). There were no significant differences in other complications between the groups either (IPVP vs. IPVN; 19.2% vs. 21.4%; p = 0.838). The NRI and 3-year RFS were not significantly different between the two groups. Conclusion: Regarding LRPPG, preserving the IPV did not help prevent DGE and resulted in no significant difference in the outcomes.
