Pylorus-preserving pancreatoduodenectomy for pancreatic head cancer after surgery for esophageal cancer with gastric tube reconstruction in a long-term survivor: A case report

摘要

Introduction To maintain the blood circulation of the gastric tube in pylorus-preserving pancreatoduodenectomy (PPPD) for periampullary cancer after esophagectomy for esophageal cancer, it is necessary to preserve the gastroduodenal artery and its branch, the right gastroepiploic artery, which are usually resected for more convenient, complete, and effective lymph node dissection. Here we report the case of a patient with a postoperative survival period of more than 5 years. Presentation of case A 79-year-old man, who underwent subtotal esophagectomy and gastric tube reconstruction 11 years ago, was diagnosed with pancreatic head cancer during routine examination 5 years after the esophageal surgery. After placement of a coronary artery stent for an arterial branch stenosis incidentally found during preoperative screening electrocardiogram, he underwent pancreatic surgery. As the tumor did not extend to the anterior surface of the pancreas and as there were no swollen lymph nodes in the area, the gastroduodenal artery, the gastroepiploic artery and vein could be preserved. Elective PPPD was conducted without incident, and good preoperative gastric tube circulation was maintained postoperatively. Reconstruction was performed according to the modified Child procedure with duct-to-mucosa stentless pancreaticojejunostomy. The postoperative course was uneventful and though it took the patient a long time to overcome the physical decline, he remains alive with no recurrent disease over 5 years post-operation. Conclusion Although PPPD may be performed after esophagectomy with gastric tube reconstruction, it is still unclear how the risk of recurrence is affected. Therefore, the indications of this procedure should always be carefully considered.
