SYSTEMIC amyloidosis frequently involves the gastrointestinal tract and may result in obstruction, malabsorption, ulceration, hemorrhage or perforation as well as impaired motility.^{1 2 3} It is unclear whether the impaired gastrointestinal motility is secondary to the effects of amyloid on the smooth muscle or on the autonomic nervous system. We report on a patient with primary amyloidosis, in whom esophageal manometric and colonic myoelectric studies revealed a widespread disorder of gastrointestinal motility. The evidence suggests that neural dysfunction contributes to the abnormal motility associated with amyloidosis.
