[Helicobacter pylori in patients with diseases of the upper part of the gastrointestinal tract].

Among the patients subjected to esophoagogastroduodenoscopy because of different clinical indications, 108 were examined for the presence of Helicobacter pylori in the antral gastric mucosa. Microbiological analysis of the antral gastric mucosa biopsies were conducted by direct microscopy, the urease test and by growing in nutritious media. Positive findings were recorded in 38 (86.36%) patients with endoscopically diagnosed chronic gastritis, 29 (80.56%) patients with duodenal ulcer and 19 (67.86%) patients with ventricular ulcer. The majority of the positive findings were recorded by direct microscopy--86 (79.63%) while the bacterial culture was positive in 66 (61.11%) cases.

[The postoperative status of the gastroduodenum--clinical and endoscopic analysis of 2 years' of hospital data].

In 72 patients operated on for gastric ulcer, hospitalized at the Clinic of Gastroenterology and Hepatology in Novi Sad within two years (1989, 1990) we analyzed clinical disorders, biochemical status and endoscopic findings. 75% of the patients were males and 25% females, mean age being 49 years. In 70.83% the two-thirds Billroth II resection was performed, in 15.28% the two thirds Billroth I resection, in 9.72% truncal vagotomy with pyloroplasty, while in 4.17% supraselective vagotomy was carried out. The mean period of time after the operation was 12 years. The majority of patients complained about gastrointestinal disorders, and manifest hemorrhage was detected in 4.17% of the patients. The symptoms of the afferent loop syndrome and early dumping syndrome were verified in one patient from each group. The endoscopic finding was normal in only 2.78%, reflux esophagitis in 6.94%, chronic gastritis with and without erosions in 86.11%, chronic anastomositis in 69.44%, recurrent ulcer in 29.16% out of which hemorrhagic ulcer was found in 4.17%. Malignant neoplasm of the stomach stump was endoscopically evidenced and histologically proved in 2.78%. Multiple associated endoscopic changes were found in 58.33%. The analysis indicates the diversity of postoperative disorders after one of the operations on gastroduodenum, requiring postoperative follow ups of the patients with subjective discomfort, appropriately set diagnosis and individual therapeutical approach to prevent more serious complications.

The evaluation of tumor markers levels in determination of surgical procedure in patients with gallbladder carcinoma.

In purpose of early diagnosis of gallbladder carcinoma, the serum levels of tumor markers CA 72-4, CA 19-9, CEA, AFP, Ferritin and beta HCG were determined in 124 patients with benign and malign diseases of gallbladder, before and 10 days after the operation. The most important clinical significance have CA 72-4 and CA 19-9, which are increased in Ca in situ and carcinoma of the first stage. These early stages of carcinoma cannot be diagnostified by preoperative echotomography, but radical operation is possible with recover by all means. These two tumor markers should be attended in risk group of patients for rising gallbladder carcinoma: calculosis and polyposis. The rest of tumor markers are increased in progressive carcinoma with infiltration of surrounding tissue and metastases.

[Modern trends in the treatment of ulcer disease (clinical study of nizatidine "Galitidine")].

By an analysis of nizatidine vs ranitidine activity, the authors show a contemporary controlled approach to the treatment of ulcer disease. In a prospective, randomized, double-blind, parallel comparative, multicentric study, the treatment of duodenal ulcer was carried out in 120 patients with H2-receptor blockers, nizatidine and ranitidine. The treatment lasted one or two months with endoscopic control of the results. The recovery of the ulcer nische in patients who received nizatidine, 150 mg twice daily over a month, was achieved in 89.75% of the cases, while in those who at the same time received ranitidine twice daily ulcer was suppressed in 84.61% of the patients; in those who received Nizatidine, 300 mg once daily it was suppressed in 88.24% of the patients. Statistically, x2 = 2.177 with p > 0.3 which shows that there is no statistically significant differences between the groups although the first group shows the best results. Adverse effects of the drugs were not observed.
