Familial amyloidosis with polyneuropathy: roentgenological and gastroscopic appearance of gastrointestinal involvement

Abstract

Forty-three patients suffering from familial amyloidosis with polyneuropathy were examined by means of barium meal, barium follow through, barium enema, cholecystogram, and gastroscopy. The findings were reviewed with respect to the presence of steatorrhea and impaired d-xylose absorption. Seven patients had gastric stasis (without gross anatomical changes) on barium meal examination and seven others on the gastroscopy. Gastroscopy revealed that another five patients had inactive peristalsis of the antrum-pylorus. Only one patient had slow transit of barium on follow through. The transit time of barium did not correlate with increased fecal fat output or decreased d-xylose absorption. Barium enema and cholecystogram were normal. The main radiological and gastroscopic finding in familial amyloidosis with polyneuropathy was reduced gastric motility.
