Obtention des digesta parvenant au gros intestin par fistulation iléo-colique post-valvulaire : Note préliminaire

: The various techniques of ileocaecal reentrant fistulation now used to collect digesta flowing from the small into the large intestine, do not provide an accurate estimate of digestion in the small intestine. Their main disadvantages are: an erroneous description of the kinetics of food passage (collection proximal to the valve or bypass of the ileocaecal valve) and changes in the ileal microflora. A new surgical technique is described (fig. 1) for collecting the digesta as they have been propelled through the ileocaecal valve, thus maintaining the functional role of the valve. When using such a technique, the digesta collected into a rubber bag must be returned to the proximal colon by the investigator. Using this post-ileocolic valve fistulation technique, the disorders commonly reported with the other techniques are avoided, and a true picture of food passage at the ileocaecal valve is obtained.
