Actual 5-year survival rates were calculated. Among patients with periampullary adenocarcinoma treated by pancreaticoduodenectomy, those with duodenal adenocarcinoma are most likely to survive long term. Five-year survival is less likely for patients with ampullary, distal bile duct, and pancreatic primaries, in declining order. Resection margin status, resected lymph node status, and degree of tumor differentiation also significantly influence long-term outcome. Establishing the presence of adenocarcinoma of the small bowel is exceedingly difficult.
Survival is contingent on prompt diagnosis.
We describe a patient with an atypical presentation of jejunal adenocarcinoma visualized via small bowel enteroclysis. A markedly abnormal scintigraphic study and a negative small bowel series does not exclude disease of the small intestine and should provide the impetus to further pursue the possibility of an obstructing lesion. The enteroclysis is a relatively safe and effective study in the preoperative diagnosis of small bowel tumors. Hereditary nonpolyposis colorectal cancer is an autosomal, dominantly inherited disease, characterized by an early age of onset, right colon predominance and an association with various extracolorectal malignancies. The tumor of the colon was histologically confirmed to be a moderately- differentiated adenocarcinoma with submucosal invasion.
