Malabsorption in relation to abdominal irradiation and quadruple chemotherapy for lymphosarcoma.

A case of severe diarrhoea and steatorrhoea following chemotherapy and abdominal irradiation for lymphosarcoma, is described. Investigations demonstrated bile acid malabsorption, and treatment with cholesytramine and a low fat diet was successful. A questionnaire was sent to thirty-two subjects who had undergone similar treatment for similar pathology and failed to demonstrate any sustained alteration of bowel function. Additionally, nine of these subjects underwent a 14C-glycocholic acid test and no evidence of interruption of the enterohepatic circulation of bile acids was found.
