[A Patient with Ascending Jejunal Mesentery Metastasis of Pancreatic Cancer after a Subtotal Stomach-Preserving Pancreaticoduodenectomy].

ABSTRACT

A 73-year-old woman underwent a subtotal stomach-preserving pancreaticoduodenectomy, wedge resection of the portal vein, and partial resection of the transverse colon for pancreatic cancer at the age of 71. After 18 months, a computed tomography image showed an 8 mm tumor in the ascending jejunal mesentery. Six months later, the tumor grew to 20 mm and had an increased FDG uptake. The tumor was diagnosed as metastasis of pancreatic cancer to the ascending jejunal mesentery. Since no metastasis was found in the other organs, resection was performed. The pathological results showed adenocarcinoma with proximal lymph node metastasis. The patient was diagnosed with ascending jejunal mesentery metastasis of pancreatic cancer. The patient has remained healthy without recurrent disease 1 year 6 months after the resection. Ascending jejunal mesentery metastasis of pancreatic cancer is a type of distant metastasis. In the absence of metastasis to other organs, it is tolerable and radical resection is possible.
