BACKGROUND & AIMS: Bloating represents a frequent gastrointestinal symptom, but the pathophysiologic mechanism responsible for its onset is still largely unknown. Patients very frequently attribute the sensation of bloating to the presence of excessive bowel gas, but not all patients with gas-related symptoms exhibit increased intestinal production of gas. It ...
Scheiman, James M.
We report two additional cases of colonic xanthomatosis associated with persistent rectal symptoms. Disordered colonic motility in the areas of lipid infiltration was documented in one patient.
