  • Title: Fecal fat measurement in the presence of long- and medium-chain triglycerides and fatty acids. Comparison of three methods.
    Author: Caliari S, Vantini I, Sembenini C, Gregori B, Carnielli V, Benini L.
    Journal: Scand J Gastroenterol; 1996 Sep; 31(9):863-7. PubMed ID: 8888432.
    Abstract:
    BACKGROUND: It has been suggested that some of the limitations of the Van de Kamer method for fecal fat measurement could be overcome with the Jeejeebhoy method or the near-infrared reflectance assay. METHODS: To test this hypothesis, a fecal fat test was carried out with the three methods, adding butter or MCT oil to the diet of four steatorrhoic patients. An in vitro recovery study of long- and medium-chain triglycerides was also performed. RESULTS: The Jeejeebhoy method measured long- and medium-chain fats more accurately than the Van de Kamer method. It found consistently higher steatorrhea values. Mean results of the near-infrared reflectance analysis resembled those of the Van de Kamer method, but with wide discordance of individual data. CONCLUSION: The Jeejeebhoy method is more accurate than the Van de Kamer method for fecal fat measurement. The difference may be clinically relevant when most fecal fatty acids derive from medium-chain triglycerides. Near-infrared reflectance may be a viable proposition only when a greater degree of approximation is acceptable.
