Abstract Purpose Pancreaticoduodenectomy (PD) concomitant with portal vein resection (PVR) often develops into digestive varices with an occurrence rate of 30–50%, and the variceal bleeding is sometimes untreatable and results in fatality. Against this issue, splenic artery (SpA) ligation during PD-PVR is emerging as an easy and effective prophylactic surgical option. The aim of this study was to investigate the significance of SpA ligation in the development of digestive varices in patients undergoing PD-PVR. Method We retrospectively investigated 97 patients with PDAC who received PD-PVR in two hospitals. Vascular reconstruction of the splenic vein (SpV) was not performed in either hospital. We assessed the occurrence rate of digestive varices in these patients in association with the performance of SpA ligation. Results The occurrence rate of digestive varices was 23%. SpA ligation was the only significant decreasing factor for the development of digestive varices (odds ratio 0.3, p = 0.035). Although SpV resection was not a significant risk factor for the development of digestive varices in all patients, SpV resection was a significant risk factor for the development of digestive varices in patients without SpA ligation, as demonstrated in previous reports. SpA ligation did not increase surgical complications or impair pancreatic function. Conclusion PD-PVR surgery was accompanied by a 23% incidence of digestive varices, and SpA ligation significantly decreased the development of digestive varices without causing clinically significant complications.
