[Upper digestive hemorrhage in acute pancreatitis].

We proposed to investigate the following parameters regarding upper gastrointestinal hemorrhage occurring in the patients with acute pancreatitis: incidence, form of manifestation, severity, correlated to the clinical and morpho-pathological form of acute pancreatitis, cause (direct causality or morbid association). The study was carried out on the inpatients of the internal-medicine and surgery units over a period of one year. For sake of accuracy the study also included the cases submitted to necropsy over a period of 5 years. The practical experience has revealed that though gastrointestinal bleeding is not a frequent complication--9.1% in the patients with acute pancreatitis and 36.3% of the necropsied cases--it is often severe, which imposes the early recognition for its adequate management.

Nonsurgical control of upper gastrointestinal hemorrhage in old age patients: intragastric norepinephrine and endoscopic alcoholization of lesions.

Of 28 consecutive patients over 64 years old, in whom endoscopy revealed gastro-duodenal ulcers with signs of recent hemorrhage (active bleeding, non-bleeding vessel or adherent clot), 14 were randomly assigned to receive endoscopic alcoholization of the lesions preceded by intragastric instillation of norepinephrine, while as controls 14 received antacids. After the applied treatment the bleeding stopped in all cases (100%) in the study group and one patient died (7.1%) after hemostasis was achieved. In the control group bleeding stopped in 12 patients (85.7%). Two patients continued to bleed and needed emergency surgery. Another patient had a major rebleed successfully treated by alcoholization. There were 4 deaths (28%): 2 patients died postoperatively and the other 2 from acute porphyria and bronchopneumonia respectively. The transfusion requirements after the entry into trial were significantly lower in the study group compared to controls (mean no. of blood units 0.79 vs. 1.71). No complications were seen with the treatment applied. These results suggest that endoscopic alcoholization of the lesions preceded by intragastric instillation of norepinephrine is an effective and safe emergency therapy for bleeding from peptic ulcers in old age patients.

Helicobacter-like organisms in gastroduodenal diseases.

The incidence of the Helicobacter-like organisms (HLO) was investigated on biopsy specimens of antral gastric mucosa, stained by the Wayson technique, in 509 patients with various gastric and duodenal diseases. The incidence of HLO was: 72.8 percent in gastric ulcer, 69.6 percent in duodenal ulcer, 69.2 percent in bulbitis, 61.0. percent in chronic gastritis, 37.5 percent in the postoperative stomach, 50 percent in gastric cancer, and 34.3 percent on healthy controls. The HLO were present over the whole year, with a peak in March. Sex and age had little influence on the HLO incidence. The Wayson staining technique proved to be a good technique of detection of HLO on gastric mucosa smears.

Biochemical changes induced by Campylobacter pylori in the gastric juice.

The biochemical changes induced in the gastric juice by the presence of Campylobacter pylori (CP) were followed up in 151 patients with various gastric and duodenal diseases. The diagnosis of CP infection was made by the urease test. In the presence of CP urea decreased in the gastric juice and ammonia increased. The sialic acid, fucose and hexoses, glucide components of the mucus glycoproteins dissolved in the gastric juice, underwent no change in the presence of CP. The hexosamines in the gastric mucus increased significantly in CP patients. Urease activity is present in the gastric juice even in the absence of CP, probably due to other microorganisms present in the human stomach. This does not exclude the use of the urease test for the diagnosis of CP infection. However the test can only be used in the bioptically removed gastric mucosa samples, not in the gastric juice.

[Campylobacter pylori infection in chronic gastritis and gastric cancer].

The present paper analyses, in correlation with histologic lesions, the incidence of infection with Campylobacter pylori (CP) in patients with chronic gastritis, operated stomach, gastric neoplasm and healthy subjects. In chronic gastritis, incidence of infection with CP is 71.6%, significantly increased in comparison with the controls, in whom the positive percentage is 37.5. The most of the patients in this group suffered from superficial chronic gastritis. In the group with operated stomach, the CP infection included 48% of the patients studied; all had superficial chronic gastritis. In gastric cancer, CP bacteria appeared in 50% of cases. CP may represent a pathogenetic ring that starts the gastric process.

Campylobacter pylori infection in gastric and duodenal ulcer.

The incidence of infection with Campylobacter pylori (CP) in gastric ulcer (GU) and duodenal ulcer (DU) and its correlation with the gastritis lesions associated to the two diseases, was investigated. In GU the incidence of CP infection was 76.3%, close to that in DU (71.4), but different from controls (33.3%). Chronic gastritis associated to gastric or duodenal ulcer is of variable severity, CP infection being the more often encountered the higher the severity of gastritis. Presence of CP was also observed in 75% of the cases associated also with intestinal metaplasia from UG. The diameter of CP-positive GU was significantly increased as compared with that in CP-negative GU. Type I GU was associated with CP infection in 81.8% of the cases. The results obtained allowed the conclusion that in GU and DU the incidence of CP infection is significantly higher as compared with that in controls but the pathogenetic relationship ulcer-bacterium is not yet elucidated.
