Study of the serotonin content in the blood for evaluation of different methods of gastric resection (Russian)

In 114 patients the serotonin level in the blood was studied by means of the fluorimetric method. A group of healthy persons was also observed, in whom the level of the serotonin in the blood in fasting condition was 0.189 γ/ml. The dynamics of the serotonin was studied in relation to the phase of digestion: in the intact stomach with normal passage of food, at 15-20 min after a meal the serotonin level had some tendency to decrease; after gastric resection by the Billroth II method it remained stable, but in the majority of patients it was elevated. After gastric resections with gastroplasty the serotonin level had a tendency to decrease. The figures of the serotonin could be used for functional evaluation of different methods of gastric resection.
