Gastric amyloidosis with massive bleeding requiring emergency surgery.
We report a 66-year-old woman who had massive bleeding from a gastric ulcer complicating primary systemic amyloidosis, in whom emergency surgery proved lifesaving. Physical examination revealed anemia and macroglossia. Gastroscopy was performed, and an extensive, irregular, hemorrhagic ulcer was found in the gastric body. Biopsy resulted in a diagnosis of amyloidosis. On the 11th hospital day the patient went into shock as a result of a massive hemorrhage. Emergency surgery was performed, but the extent of the submucosal lesion in the stomach could not be identified, and total gastrectomy was unavoidable. Histological examination of the surgical specimen and biopsy tissue collected from other organs revealed amyloid deposition extending from the submucosa to the muscularis propria of the stomach. There was also deposition of large amounts of amyloid around the small blood vessels in the liver and under the mucosa of the small intestine. The amyloid was AA-antibody-negative and resistant to treatment with K2MO4, and a diagnosis of AL-type systemic amyloidosis was made. The patient's general condition recovered after the operation, but on the 103rd hospital day, she experienced sudden onset of arrhythmia and died. Patients with amyloidosis in whom gastrointestinal surgery is performed are rare; only 41 cases, including our own, have been reported in the Japanese literature since 1972.
