Alternative hepatic arterial reconstruction technique in a case of total pancreaticoduodenectomy after celiac artery resection in pancreas cancer: Iliac-hepatic bypass

摘要

Surgery is the only treatment method in pancreatic cancer. Unfortunately, metastatic diseases or invasion of the main vascular structures are observed in a majority of cases at the time of diagnosis; these structures originate from the body, neck, and tail of the pancreas and are considered inoperable. The first celiac artery resection for the treatment of cancer was described by Appleby in 1953. Here, we describe our hepatic artery reconstruction technique in a case with pancreatic body cancer. A 37-year-old male patient was admitted to our emergency department due to syncope. The patient was diagnosed with acute renal failure secondary to fluid loss. Thereafter, his general condition was stable and laboratory results improved. Abdominal computed tomography was performed. Pancreatic cancer originating from the pancreatic body was detected. A pancreatic biopsy was performed and neoadjuvant gemcitabine and paclitaxel chemoradiotherapy were initiated. Surgical treatment was recommended for the identification of regression after neoadjuvant chemoradiotherapy. Following intraoperative Doppler ultrasonography, en bloc distal pancreatectomy and splenectomy involving the celiac artery trunk and total gastrectomy were performed. However, surgical margin reliability in frozen section revealed that the tumor was still present. Therefore, the surgical procedure was replaced with total pancreaticoduodenectomy. Hepatic artery reconstruction was performed from the left main iliac artery using a 4-mm ringed GORE-TEX® graft. The iliac-hepatic bypass for hepatic artery reconstruction in pancreatic cancer could be an alternative surgical technique.
