“…Fat balance studies were found by Kalser, Roth, Tumen, and Johnson (1960) and Doig and Girdwood (1960) to be more sensitive than nitrogen as an index of malabsorption after resection. Steatorrhoea may be more pronounced than creatorrhoea after resection due to a decrease in bile-salt reabsorption (Hofmann and Grundy, 1965), which in turn would interfere with absorption of fat but not the small intestine (Kremen and others, 1954;Pietz, 1956;Reynell and Spray, 1956).…”
