[A case of small intestinal cancer in the efferent loop of roux-en Y reconstruction after total gastrectomy and liver metastases].
A 61-year-old woman, who had undergone total gastrectomy and distal splenopancreatectomy with Roux-en Y reconstruction for a gastric cancer 16 years earlier, was found primary small intestinal cancer located in intestinal loop of Roux- en Y in gastrointestinal endoscopy for abdominal pain. Computed tomography showed liver metastases which were 8 cm in diameter at lateral segment and 1 cm in diameter at segment 8 of the liver. In the operation, the small intestinal cancer was located in the ρ-anastomosis in the loop of Roux-en Y with the other jejunum fistula. We performed lateral segment hepatectomy, partial hepatectomy of segment 8, partial resection of small intestine including loop of ρ-Roux-en Y, partial resection of transverse colon, and restoration Roux-en Y again. We succeeded in preserving double tract anastomosis at duodenum. Histological examination revealed a moderately differentiated adenocarcinoma of the small intestine and segment 8 of the liver, and angiomyolipoma of lateral segment of the liver. It is extremely rare for small intestinal cancer to arise in a loop of Roux-en Y reconstruction caused by total gastrectomy.
