PURPOSE: Splenic vein (SV) ligation combined with portal vein (PV)/superior mesenteric vein (SMV) confluence resection during pancreaticoduodenectomy (PD) is reported to cause left-side portal hypertension (LPH). The purpose of this study was to present our technique of the SV reconstruction and to evaluate the surgical outcomes with/without SV ligation during PD.
METHODS: Twenty-four patients undergoing PD with PV and/or SMV resection and being followed over 4 months after surgery between March 2013 and December 2019 in our hospital were evaluated. Resection of the PV/SMV confluence were performed in 14, and SV reconstruction was successfully performed in 3. Presence of LPH was assessed by examining changes in splenic volume, newly venous collateral formation, and platelet counts before and 4-8 months after PD. Surgical technique is the direct anastomosis between SV and PV.
RESULTS: Splenic volume ratio was significantly higher in the SV ligation group (n = 11) than in the SV preservation group (n = 13) (median (range) 1.11 (0.57-1.62) vs. 1.68 (1.05-2.22), p < 0.01), but no significant differences were found in the incidence of newly formed venous collaterals or platelet counts between groups.
CONCLUSION: SV ligation may represent the cause of LPH after PD combined with resection of PV/SMV confluence. Our simple procedure may help decrease the incidence of LPH.
