[Surgical approach to abdominal aortic aneurysm with malignant alimentary tract tumor: report of three cases].
The clinical courses of three cases with various alimentary tract malignant lesions coincidental with abdominal aortic aneurysm were reported. Of those three patients, a simultaneous resection of the malignant lesion and aneurysm was carried out in two patients, while an secondary abdominal aneurysmectomy following the resection of the malignant lesion was done in one patient. A 70-year-old man with cancer of the cecum and an infra-renal abdominal aneurysm, was diagnosed preoperatively, and a simultaneous right hemicolectomy and aneurysmectomy were carried out. In the other patient, a 77-year-old man, presence of the gastric cancer was incidentally found at laparotomy and a 75 percent gastrectomy and an aneurysmectomy were carried out. In the third patient, both gastric cancer and an abdominal aneurysm were detected preoperatively. Distal partial gastrectomy was performed first because of severe epigastralgia and an asymptomatic aneurysm. The abdominal aneurysmectomy was carried out six months later. All patients were treated by daily administration of Cefazolin sodium or cefalotin sodium (4-10 g) and Dibekacin sulfate (200 mg) for seven to ten days postoperatively. In the case of second look operation, however, Fosfomycin 2-4 g/day was added to the above mentioned drug following the aneurysmectomy. All tolerated surgery well without any signs of infections. The first patient died on the 57th postoperative day from panperitonitis carcinomatosa following an episode of intestinal obstruction. Selection of the operative approaches for patients having both an alimentary tract malignant tumor and an abdominal aortic aneurysm was difficult, although the initial surgical intervention for the more life threatening lesion would be better justified.(ABSTRACT TRUNCATED AT 250 WORDS)
