[The results of pylorus-preserving resection of the stomach].

The functional results of pylorus-preserving resection of a stomach (PRS) in 68 patients with gastric ulcer disease were studied. According to the data of gastroscintigraphy and hepatoscintigraphy, it was established that number of patients with decreased motor-evacuatory function (MEF) of the stomach reduced from 31% before the operation to 11% at the long-term period after PRS. Duodenogastric reflux was noted in 10% of the patients as compared with 47% before the operation. MEF of the stomach normalized within 3-6 mos after the operation. Acid-producing function of the stomach after PRS steadily decreased until the development of a hypoacidic state. Basal pH of gastric, body at the long-term period was 3.39 +/- 0.59. An excellent and good result according to Visick scale was noted in 67 (98.5%) patients, a satisfactory one--in 1 (1.5%).
