Abstract

Background: While the safety of pancreaticoduodenectomy (PD) has improved, the high level of difficulty associated with this operation means that the procedure carries a high mortality rate compared to other gastrointestinal operations. Various trials have been implemented in efforts to reduce the incidence of complications after PD. In particular, a large amount of intraoperative bleeding and the use of red blood cell transfusions are reportedly risk factors for postoperative complications after PD. Aim: In an attempt to reduce the amount of intraoperative bleeding during PD, consideration was given to the anatomical characteristics of the region of the pancreatic head, and the gastroduodenal artery (GDA) and inferior pancreaticoduodenal artery (IPDA) were ligated in advance of separating the head from the portal vein. We herein report the use of ultrasonography during PD to facilitate the early identification and ligation of the IPDA. Case Presentation: A 72-year-old female was diagnosed with pancreatic cancer and underwent pylorus-preserving pancreatoduodenectomy. We used ultrasonography during the operation to initially identify the IPDA and then ligate it in advance, after which the GDA was ligated before separating the pancreatic head from the superior mesenteric artery and portal vein. Identification of the IPDA was performed with the SMA as a guide using ultrasonography in Doppler mode. The amount of intraoperative bleeding was 235 ml. The patient left the hospital without any postoperative complications and has since demonstrated a good postoperative course, with no evidence of recurrent disease. Conclusions: Early ligation of the IPDA using intraoperative US is non-invasive and makes it simple to identify the IPDA. This method may be a useful technique for reducing intraoperative bleeding during the normal course of PD procedures.
