Primary tubular adenocarcinoma arising in the duodenal limb of reconstructed gastroduodenostomy for signet-ring cell carcinoma of the stomach

摘要: Adenocarcinoma of the small intestine is uncommon. Due to this paucity and lack specificity symptoms, patients are usually seen late in course their illness, when curative therapy, mainly represented by extensive surgical resection, unlikely. The authors report a case primary well-differentiated tubular adenocarcinoma (T4N0M0) arising duodenal limb reconstructed Billroth I gastroduodenostomy, 9 years after distal gastrectomy for signet-ring cell carcinoma stomach (T4N0M0). Evidence excluding possibility recurrence gastric cancer was based on different histologic pattern, long disease-free interval, other features second neoplasm. Relatively early diagnosis neoplasm, followed therapy made possible onset obstructive symptoms favorable anatomical location tumor.
