Metachronous primary carcinoma of small bowel following resected colorectal carcinoma: a report of three cases.
Three cases of metachronous adenocarcinoma of the large and small bowel are reported. The small-bowel lesions were not even suspected preoperatively and were diagnosed after extensive pathologic study. Though rare, metachronous primary carcinoma of the small bowels must be considered in a patient with intestinal obstruction or hemorrhage following colorectal cancer surgery. Pre-operative diagnosis, which demands a high index of suspicion and careful technical evaluation, is crucial in determining the overall surgical management of the patient.
