Reconstructing spleno‐mesenterico‐portal cofluence by bifurcated allogeneic vein in local advanced pancreatic cancer—a feasible method to avoid left‐sided portal hypertension

BACKGROUND: Left‐sided portal hypertension is usually found in patients undergoing pancreaticoduodenectomy (PD) with spleno‐mesenterico‐portal (S‐M‐P) confluence resection. This study is to explore the outcomes of S‐M‐P confluence reconstruction after resection by using bifurcated allogeneic vein. M...

Sumario:BACKGROUND: Left‐sided portal hypertension is usually found in patients undergoing pancreaticoduodenectomy (PD) with spleno‐mesenterico‐portal (S‐M‐P) confluence resection. This study is to explore the outcomes of S‐M‐P confluence reconstruction after resection by using bifurcated allogeneic vein. METHODS: Clinicopathologic data of patients who underwent extensive PD with S‐M‐P confluence resection for carcinoma of pancreatic head/uncinate process in our hospital between December 2011 and August 2018 were retrospectively reviewed and clinical outcomes of vein reconstruction after resection were analyzed. RESULTS: Of the 37 patients enrolled, S‐M‐P reconstruction by bifurcated allogeneic vein was performed in 24 cases (group 1) and simply splenic vein ligation in 13 cases (group 2). Items including pathological results, blood loss, and complications were comparable between the two groups, operation time was longer in group 1 (573.8 vs. 479.2 min, p = 0.018). Significantly decreased platelet count (205.9 vs. 133.1 × 10(9)/L, p = 0.001) and increased splenic volume (270.9 vs. 452.2 ml, p < 0.001) were observed in group 2 at 6 months after operation. The mean splenic hypertrophy ratio was 1.06 in group 1 and 1.63 in group 2, respectively (p < 0.001). There were four patients with varices were found in group 2, none in group 1. CONCLUSIONS: Without increased complications, reconstructing S‐M‐P confluence by bifurcated allogeneic vein after resection may help to avoid left‐sided portal hypertension.
