The role of endoscopic thrombin injections in the treatment of gastroduodenal bleeding.

One hundred and ninety-one patients who had emergency endoscopy performed for acute gastroduodenal haemorrhage and were found to be bleeding actively (N = 141) or to have an ulcer containing a non-bleeding visible vessel (N = 50) were studied. Patients with active bleeding were divided into two groups: group I included 47 patients in whom diagnostic endoscopy was performed and conventional management applied; and group II contained 94 patients in whom, apart from conventional treatment, endoscopic thrombin injections could also be offered. Fifty patients with non-bleeding visible vessels were admitted to a prospective randomised trial and assigned to either endoscopic injections (group A, N = 25), or no primary endoscopic treatment (group B, N = 25). The introduction of the injection therapy in patients who were actively bleeding resulted in a significant reduction of the emergency operation rate (70.2% v. 12.8%; P < 0.001), mortality rate (21.3% v. 8.5%; P < 0.05 and blood transfusion requirements (4,220 +/- 1,840 ml v. 1,980 +/- 980 ml; P < 0.05). Endoscopic thrombin injections of non-bleeding visible vessels reduced the rebleeding rate (40% v. 4%; P < 0.01) and blood transfusions (2,939 +/- 1070 ml v. 1,390 +/- 552 ml; P < 0.05).

Aspiration cytology in the diagnosis of malignant tumors in children.

On the basis of 65 fine-needle aspiration biopsies (FNAB) the efficiency of aspiration cytology combined with immunocytochemistry in preoperative diagnosis of malignant tumors in children was evaluated. All FNAB were performed under ultrasound or fluoroscopy guidance. There were no false-positive diagnoses. Morphological type of the tumor was properly diagnosed preoperatively in 50 patients. In 10 aspirates, the tumor type could not be diagnosed on the basis of light microscopy and immunocytochemistry. Due to technical reasons, five false-negative diagnoses (7.7%) were made. This study showed that FNAB is a safe, rapid, and effective method, which enables preoperative diagnosis of children's tumors in most cases.

Synthetic antiproteases in acute pancreatitis: an experimental study.

Acute pancreatitis was induced in 19 anesthetized dogs by retrograde injection of bile mixed with trypsin into the pancreatic duct. Two groups, of six animals each, were treated with intravenous infusion of synthetic antiproteases: gabexate mesilate and nafamostat mesilate in doses of 1 mg/kg per hr. One group of seven animals remained untreated. Two untreated dogs died during the experiment. All the treated dogs survived. Hemodynamic data were monitored hourly during a 6-hr observation period. In the untreated animals, cardiac output, mean arterial pressure, and left ventricular stroke volume decreased rapidly; an increase of pulmonary vascular resistance and systemic vascular resistance was observed. Synthetic antiproteases, given as a therapy, improved the hemodynamic parameters significantly and prevented the animals from developing shock. Gabexate mesilate and nafamostat mesilate seem to be of value in the treatment of experimentally produced acute pancreatitis in dogs.

Beneficial effect of therapeutic infusion of nafamostat mesilate (FUT-175) on hemodynamics in experimental acute pancreatitis.

Acute pancreatitis was induced in 13 anesthetized dogs by retrograde injection of bile mixed with trypsin into the pancreatic duct. Six animals were treated with intravenous infusion of new synthetic antiprotease. Nafamostat Mesilate, at a dose of 1 mg/kg/h. Four out of seven untreated animals died during the experiment. All the treated dogs survived. Hemodynamic data were regularly monitored during a ten-hour observation period. Cardiac output, mean arterial pressure and left ventricular stroke volume decreased rapidly in the untreated animals. An increase in systemic vascular resistance and pulmonary vascular resistance was observed in dogs without treatment. Nafamostat Mesilate given as therapy significantly improved the hemodynamic parameters, and prevented the animals from developing shock. The study demonstrates an advantageous influence of synthetic antiprotease Nafamostat Mesilate on the course of acute experimental pancreatitis.
