[Fecal fermentation in meteorism].
An old test to investigate fecal fermentation was modified with the purpose of changing it from qualitative to quantitative. The modified test consists in placing in stove, at 37 degrees C for 24 hours, 5 grams of feces, suspended in water. The fermentable alimentary residues, present in the feces, suffer the action of bacteria, also there present, yielding gas that is collected and measured. Using the test, fecal fermentation was determined in 3 groups of individuals: a) 40 patients with meteorism that had persisted or improved only slightly or fairly with treatment; b) 28 apparently healthy subjects; and c) 6 patients with meteorism that had disappeared or become minimal with treatment. In the group of 28 apparently healthy subject, the obtained results varied from 0.1 to 1.1 ml gas/24 h., with a mean +/- s.d. of 0.55 +/- 0.29 ml. gas/24 h. When a distribution curve was made with the results obtained in the group of 40 patients with meteorism, these results separated into 2 subgroups: one subgroup with 28 patients, in whom results varied from 1.0 to 13.3 ml. gas/24 h., with a mean of 4.8 gas/24 h. (only) in 1 of these 28 patients a normal result of 1.0 ml. gas/24 h. was obtained, while in the remaining 27 patients results of 1.5 or more ml. gas/24 h. were obtained); and the other subgroup with 12 patients, in whom results varied from 0.0 to 0.9 ml. gas/24 h., with a mean of 0.29 ml. gas/24 h. Finally, in the group of 6 patients with successfully treated meteorism, results were from 0.1 to 0.9 ml. gas/24 h., with a mean of 0.4 ml. gas/24 h. The above mentioned results strongly suggest the existence of a relationship between meteorism and exagerated fecal fermentation. The nature of this relationship has not yet been completely clarified. However, the test used to determine fecal fermentation already promises to be very helpful for a better understanding and management of meteorism.
