[The vagotomy results in relation to the predominance of neural reflex or hormonal mechanisms regulating acid production in patients with a chronic duodenal ulcer].

Results of prognostic tests of vagotomy were studied in 365 patients with chronic duodenal ulcers (CDU). It was established that the atropin test can not be taken as the main criterion of prognosis of vagotomy. However, according to its results the patients can be divided into 2 groups: atropin sensitive (69.3%) and atropin-resistant (30.7%). According to the parameters of the atropin test and the night gastric secretion the patients were divided into 3 groups: favorable (45.7%), doubtful (31.0%) and unfavorable (23.3%) prognosis of effectiveness of vagotomy with draining operations of the stomach.
