[The role of macroscopic traits in the diagnosis and prognosis of the polyp morphological type].

The aim of this work was to compare macroscopic traits of polyps and their morphological structure. A total of 97 (82.9%) patients with hyperplastic polyps and 20 (17.1%) with adenomatous polyps were examined. It was shown that neither the shape, colour, surface structure nor the degree of erosion reflects morphological features of the polyps. Hyperplasia of polyps can be reliably (p < 0.01) diagnosed only from the combination of their multiple character and localization in the stomach. All isolated and single polyps are subject to morphological examination.

[Diagnostics of the residual stomach polyps].

This article presents the comparative analysis of the macroscopic and the morphological characteristics of primary and remote residual stomach polyps. There were significant signs of macroscopic residual polyps, allowing them to diagnose by endoscopic examination. Histological features allow us to attribute residual polyp group of hyperregeneratory.

[Polyposis of the stomach. Endoscopic treatment or follow-up?].

Out of 3243 patients with gastric polips, polyposis was diagnosed in 298 ones including 135 cases of complicated and 163 cases of uncomplicated forms. Hyperplastic polips were diagnosed in 281 patients. Along with hyperplastic polyps, solitary adenomas were diagnosed in 9 cases, Peitz-Jegerc polyps - in 6, and juvenile polyps - in 2. Polypectomy was performed in 153 patients: partial - in 104, and total - in 49. Follow-up was carried out in 98 non-operated patients, indications for endoscopic surgery were seen in 18 cases. After partial endoscopic polypectomy, repolypectomy was performed in 24 cases: single - in 8, multiple - in 16. Repeated endoscopic treatment after total polypectomy was performed in 3 patients. There were no cases of polyp transformation into cancer. Open surgical treatment was not performed. There were no severe complications after endoscopic treatment.

[A pH-probe for endoscopic parietal topographical pH-metry].

A pH-probe for endoscopic parietal topographical pH-metry was developed. The probe has a circular measuring electrode and a cutaneous silver chloride reference electrode. Clinical testing of the developed probe was performed to compare it with a conventional end electrode. It was found that the new pH-probe with circular antimonial electrode for pH measurement at the surface of the mucous coat of upper gastrointestinal tract in a fasting patient considerably increases the accuracy of pH measurement at the site of acid glands. Recommendations for examination of acid-forming and alkalizing functions of stomach and determination of the boundaries of the main regions of stomach during endoscopic examination are given.

[The surgical and endoscopic treatments of benign submucosal tumors of the esophagus, stomach and duodenum]. / Khirurgicheskoe i éndoskopicheskoe lechenie dobrokachestvennykh podslizistykh opukholei pishchevoda, zheludka i dvenadtsatiperstnoi kihki.

Analysis of the results of various modes of treatment and follow-up of 160 patients with benign submucosal tumors (BST) was carried out. Most often histological type of BST was leiomyoma (43.7%). BST were mainly located in the stomach (68.7%). 22 patients underwent open operations, 37--endoscopical removal of BST, 101 patients were followed-up from 5 to 10 years. The analysis of the material makes it possible to come to the conclusions about advisability of endoscopical treatment. The results of which are not inferior to surgical method of treatment. In patients with absence or slow growth of BST endoscopic follow-up is valid.
