[Selection of the method of reoperation after closure of perforated duodenal ulcer].

The work deals with the study of the fate of patients who underwent closure of a perforated opening in a duodenal ulcer. In 27-53% of such patients subsequent nonoperative treatment was ineffective and they were subjected to reoperation: resection of the stomach or vagotomy. After comparative evaluation of these two reoperations on the grounds of the clinical data and the secretory and evacuating function of the stomach which had been operated on, the authors give preference to selective proximal vagotomy as an operation that is more physiological and devoid of the short-comings of gastric resection.

[Intraoperative pH-metry in the prevention of incomplete vagotomy and ischemia of the gastric wall in selective proximal vagotomy].

Experiments were conducted on 14 mongrel dogs to appraise the validity of the results of intraoperative pH-metry in the control of vagotomy completeness depending on the force of pressure exerted on the pH electrode with consideration for the type of a pH catheter used. The level of parietal pH increased with elevating pressure force due to diminished circulation in the gastric wall. The encountered diminution of circulation in the gastric wall after SPV increases still more the pH level and reduces the amplitude of its growth even in areas with maintained parasympathetic innervation with the use of histamine, which raises the probability of incomplete vagotomy. The authors conclude that pH-metry by slight application of the pH electrode to the gastric wall raises the validity of the values recorded and reduces the frequency of incomplete vagotomy in patients operated on in the clinic by 4.7 times. Increase of parietal pH to more than 6.7, irrespective of the force of the exerted pressure, is an indirect sign of ischemia of the gastric wall.

[Functional status of the operated-on stomach in patients with post-burn esophageal stenosis].

The article discusses the results of complex functional examination of the stomach in 41 patients with post-burn stenosis of the esophagus in different postoperative periods. Group I consisted of 21 patients with isolated chemical burns of the esophagus, group II was made up of 20 patients with combined chemical burns of the esophagus and stomach. Special new methods of examination (3-canal and endoscopic pH-metry, balloonography, radioisotope gastroscintigraphy, radioimmunological test for the hormone gastrin) were conducted to study the functional condition of the stomach which had been operated on. Objective evaluation is possible only by complex use of special methods of examination.

[Association of stomach and duodenal ulcers and diaphragmatic hernia].

On the basis of complex examination of 83 patients with the ulcer disease including ionomanometry 25 of them were found to have hiatal hernia. Specific features of the clinical picture of this combination are described. The detection of hiatal hernia in patients with the ulcer disease allows the correction of the valve mechanism of the esophago-gastric transition to be simultaneously fulfilled during the operation.
