Abstract:
Objective To study the impact on the use of branched vascular allografts in the prevention of left regional portal hypertension after pancreatic cancer operations.Methods This retrospective study included 25 patients who underwent pancreaticoduodenectomy for pancreatic head cancer which involved the portal vein,superior mesenteric vein and splenic venous confluence between January 2011 to December 2017 in the Beijing Chao Yang Hospital,Capital Medical University.These patients underwent "en bloc" resection of the spleno-mesenterio-portal (SMS) venous axis with replacement of a branched vascular allografts.They were studied to see whether gastroesophageal varices were found on gastroscopy and whether there were any changes in leukocyte,platelet and splenic volume before and after the operation to determine the incidence of left regional portal hypertension after operation.Results During the follow-up period,all the portal vein,superior mesenteric vein and splenic vein anastomoses were unobstructed and without any thrombosis.No new varices were found on gastroscopy.There were no significant differences in the white blood cell count,platelets count and splenic volume before and after the operations (all P＞0.05).The 25 patients had no left regional portal hypertension.Survival time and one year survival rate of the patients were (20.2±3.7) months and 44.0％.Conclusion Branched vascular allografts effectively prevented the occurrence of left regional portal hypertension after radical pancreaticoduodenectomy with resection of SMP.
