Pancreaticoduodenectomy with Preservation of Collateral Circulation or Revascularization for Biliary Pancreatic Cancer with Celiac Axis Occlusion: A Report of 2 Cases

摘要

Case series Patients: Male, 74 ? Female, 69 Final Diagnosis: Hepatobiliary pancreatic cancer Symptoms: Fever ? jaundice ? vomiting Medication: — Clinical Procedure: — Specialty: Surgery Objective: Unusual setting of medical care Background: In cases of celiac axis occlusion requiring pancreaticoduodenectomy for malignancy, both oncologic curability and control of hepatic arterial flow must be considered, but the operative strategy is undeveloped. Case Reports: Case 1: A 74-year-old man was diagnosed with hilar cholangiocarcinoma with celiac axis stenosis. The collateral from the superior mesenteric artery ran through the pancreas head but no invasion was observed in pre-operative imaging. Hepatopancreatoduodenectomy with preservation of a collateral was performed. Case 2: A 69-year-old woman was diagnosed with pancreas head cancer with celiac axis occlusion. The collateral from the superior mesenteric artery ran through pancreas head and tumor invasion was observed. Pancreaticoduodenectomy with bypass revascularization using a vein graft was performed. Both operations were performed safely oncologically under preoperative planning that was based on computed tomographic angiography. The operative procedure was ultimately determined by evaluation of perioperative blood flow under Doppler ultrasonography after clamping the gastroduodenal artery. Conclusions: Preoperative simulations of arterial revascularization and perioperative evaluation of blood flow are necessary for the success of this procedure.
