Successful simultaneous repair of coincidental bleeding malignant lymphoma of the stomach and expanding abdominal aortic aneurysm.

In a 61-year-old Japanese man, a concomitant bleeding gastric malignant lymphoma and expanding abdominal aortic aneurysm was evident. Bacterial studies were done for a further 32 laparotomy cases. The patient underwent abdominal aortic aneurysmectomy and partial gastrectomy simultaneously. The postoperative course was uneventful except for temporary pneumonia. The positive rate for bacterial culture in cases of gastric or colorectal cancers was significantly high compared with that in the cases of abdominal aortic aneurysm. From the viewpoint of bacterial contamination, these two operations should be done separately. However, simultaneous operations as in the current case are feasible if great care is taken.
