Interventional Radiology for Postoperative Bleeding in the Hepatobiliary and Pancreatic Region

Abstract

Even in modern times, surgery in the hepatobiliary and pancreatic region remains complicated. Various postoperative complications are experienced, especially postoperative bleeding, which is a severe and life-threatening complication that can occur within a short time. The superiority of interventional radiology over surgical reoperation has been shown as a treatment for postoperative bleeding after pancreatectomy, and it has become the treatment of first choice. Furthermore, since 2016, stent-graft (GORE VIABAHN^®) has been approved in Japan, and it is expected that the treatment results and prognosis will be improved by making it possible to preserve hepatic blood flow. This paper summarizes the findings of postoperative bleeding after pancreatic resection and hepatectomy. As an interventional radiology treatment, this paper introduces the basics of hemostasis and the basic handling of stent-grafts and coil embolization as well as other optional treatments that may be useful when stent-grafts cannot be used.
