[Show abstract][Hide abstract] ABSTRACT: Objectives:
The aim of the present study was to analyse the impact of education of patients with irritable bowel syndrome (IBS) on their quality of life.
The study was carried out at the Gastroenterology Outpatient Clinic of the Independent Public Clinical Hospital No. 4 in Lublin and Gastroenterology Outpatient Clinic of the Cardinal Stefan Wyszyński Regional Specialist Hospital in Lublin in the years 2010-2011. The quality of life was analysed using the Quality of Life Questionnaire (QOL-Q R. Schalock, K. Keith). The group of 83 patients with the diagnosis of irritable bowel syndrome, who gave their consent for inclusion in the study, was provided with information about the essence of the disease, disease-related diet and lifestyle, course of the disease, medications, and check-ups.
Our patients educated by the physician, nurse and those provided with written information had substantially higher scores in multi-dimensional aspects of the quality of life after education. Six months after education patients with IBS showed a significantly higher quality of life in all aspects, i.e. Satisfaction, Competence/productivity, Empowerment/independence and Social inclusion/community integration. The understanding of the essence of their disease contributed to a decrease in anxiety associated with the neoplastic disease and worrying symptoms, which significantly reduced the incidence of complaints.
1. Quality of life of patients with irritable bowel syndrome is substantially reduced in all the examined spheres. 2. Education of patients with IBS resulted in enhanced quality of life and reduced disease-related complaints. 3. Education of patients with IBS plays a significant role in the entire therapeutic process.

This tumour may look like an ulcer and can be a cause of abdominal pain, nausea, and bleeding from the gastrointestinal tract. We reported a 61-year-old women complaining of stomachache for several months. Gastroscopy revealed a tumour with ulceration in the prepyloric part of the stomach. Helicobacter pylori infection was also present. Helicobacter pylori eradication and prolonged treatment of proton pump inhibitors did not decrease the ailments or the size of the tumour. It was not possible to determine the nature and origin of the tumour by carrying out examinations such as endoscopic ultrasound and computed tomography of the abdomen. Only after surgery and histopathological examination with immunohistochemistry was this tumour identified as a neurofibroma. In order to differentiate the tumour the following immunohistochemical examinations were carried out: CD34 (slightly +), CD117 (-), S-100 (+), desmin (-), NSE (+), GFAP (-), SMA (-), bc12 (-), CD99 (-), ALK1 (-), and MiB (1-1.5%). In such cases excision of the tumour is the preferred treatment.
[Show abstract][Hide abstract] ABSTRACT: Background:
There is a growing evidence that matrix metalloproteinase (MMP)-2 and MMP-9 (gelatinases) play an important role in the pathogenesis of numerous disorders, especially with inflammatory etiology and extracellular matrix (ECM) remodeling. Despite the fact that gelatinases involve in liver cirrhosis is provided in the literature, their role in the pathogenesis of chronic pancreatitis and non-specific inflammatory bowel diseases is still under investigation.
We carried out a PubMed search of English-language articles relevant to the involvement of gelatinases in the pathogenesis of liver fibrosis, pancreatitis, and non-specific inflammatory bowel diseases.
The decreased activity of gelatinases, especially MMP-2, is related to the development of liver fibrosis, probably due to the decrease of capability for ECM remodeling. Similar situation can be found in chronic pancreatitis; however, reports on this matter are rare. The presence of non-specific inflammatory bowel diseases results in MMP-9 activity elevation.
The fluctuation of gelatinases activity during liver fibrosis, chronic pancreatitis and non-specific inflammatory bowel diseases is observed, but the exact role of these enzymes demands further studies.

Light chain amyloidosis (AL) is recognised as the most common form of systemic amyloidosis. Light chains are deposited in the majority of bodily organs, and accumulation of them in the liver produces hepatomegaly. We report a case of AL-systemic amyloidosis with liver involvement in a 71-year-old woman. Hepatomegaly, weight loss and general malaise were the first manifestations of the disease. Liver biopsy found amyloid deposits along the sinusoids as well as in the space of Disse, inside the vascular wall and in connective tissue of the portal tracts, which showed a positive reaction in Congo Red stain. Further diagnosis showed the presence of systemic amyloidosis. The patient was put on cyclophosphamide and steroid therapy.
[Show abstract][Hide abstract] ABSTRACT: Heterotopic or ectopic tissue is a congenital anomaly defined as the presence of the tissue outside its normal location. This tissue is usually discovered incidentally and may be asymptomatic or may present with non-specific gastrointestinal (GI) symptoms. Two types of heterotopic tissues, pancreatic and gastric, predominantly occur in the GI tract. The frequency of ectopic pancreas found in autopsy studies is approximately 0.5%-13.7%. Heterotopic pancreatic tissue can be located anywhere along the GI tract; the most common sites are the stomach (27.5%), duodenum (25.5%), colon (15.9%), esophagus, and Meckel`s diverticulum. It has been found in approximately one per 500 surgical procedures involving the upper GI tract. It can also occur in the gallbladder, biliary tract, spleen, liver, omentum, mesentery, lung and pelvis. Likewise, heterotopic gastric mucosa can occur anywhere along the GI tract yet its most common locations are different from those of heterotopic pancreatic tissue. In this paper we present heterotopy characteristics in particular locations. Gastric or pancreatic heterotopy, although rare, should be taken into consideration in differential diagnosis of unexplainable abdominal pain, bleeding from the GI tract or weight loss. Once heterotopy has been detected, appropriate treatment can be implemented which will reduce the risk of complications.

[Show abstract][Hide abstract] ABSTRACT: Iron is an essential micronutrient of almost all organisms, which is involved in many metabolic processes. Disorders of serum iron balance that relate mainly to its deficiency are frequently observed in patients with liver diseases. The aim of the study was the evaluation of serum iron parameters in patients with different chronic liver diseases and analysis of the relationships between serum level of iron, ferritin and transferrin in women and men in groups examined.
The study includes 424 patients: 151 with alcoholic liver cirrhosis (ALC), 53 with nonalcoholic fatty liver disease (NAFLD), 54 with autoimmune hepatitis (AIH), 19 patients with hepatocellulare cancer (HOC), 34 with primary biliaris cirrhosis (PBC), 39 with chronic HCV hepatitis, 48 with chronic HBV hepatitis, 15 with primary sclerosans cholangitis (PSC) and 11 patients with hemochromatosis. Forty two healthy volunteers were the control group.
The highest mean serum level of iron was observed in patients with hemochromatosis and was 278.56 +/- 25.04 mg/dl. The mean level of iron was statistically significant different in patients with HCC in comparison to the patients with ALC (p = 0.0000), with AIH (p = 0.0108) and NAFLD (p = 0.00768). The mean level of ferritin was statistically significantly higher among patients with hemochromatosis (p = 0.0000), with ALC (p = 0.0037) and NAFLD (p = 0.0442) than in the controls. Patients with AIH, HCC, HCV infection, PSC and hemochromatosis showed higher serum level of transferin than the controls (p = 0.0000). The mean level of iron and ferritin was lowerin women than in men in the patients with ALC (p = 0.0088, p = 0.0018 respectively). The mean level of ferritin was significantly lower in men than in women among patients with NAFLD. (p = 0.0065). There were no statistically significant differences in the mean level of examined parameters between the sexes.
Reduced serum level of iron is observed in chronic liver diseases. Elevated ferritin level is typical for patients with ALC and NAFLD. Differences in the level of iron, ferritin and transferin between men and women concemrn the patients with ALC while among patients with NAFLD only ferritin level differences are found.

[Show abstract][Hide abstract] ABSTRACT: Background
Non-alcoholic fatty liver disease (NAFLD) refers to a very wide clinical spectrum. Advanced fibrosis that accompanies disease leads to the development of cirrhosis and hepatocellular carcinoma. Thus, identification of patients with advanced fibrosis is essential. The aim of the present study was to compare the usefulness of NAFLD fibrosis and BARD scores in predicting fibrosis in NAFLD and to determine the risk factors of advanced fibrosis.
The study included 126 patients with NAFLD. Fibrosis in liver biopsy was scored on a 5-point scale. The BARD and the NAFLD fibrosis scores were compared with the biopsy findings.
Liver biopsy revealed 27 patients with advanced and 99 with mild/moderate fibrosis. Advanced fibrosis was statistically significantly more common in older patients with obesity, AST/ALT ratio ≥0.8, diabetes mellitus, and thrombocytes ≤200×103/L. Positive predictive value, negative predictive value and AUROC curve for BARD score, and NAFLD fibrosis score were 68.57%, 96.70%, 0.865 and 70.59%, 98.11%, 0.919, respectively.
Both scores are capable of ruling out advanced fibrosis and markedly reducing the need for liver biopsies in patients with NAFLD. Obesity, diabetes mellitus, thrombocytes ≤200×103/L, advanced age and AST/ALT ratio ≥0.8 are the risk factors of advanced fibrosis.

[Show abstract][Hide abstract] ABSTRACT: Recent studies have shown the key role of genetic factors in the development of chronic pancreatitis.
The aim of the study was to establish whether the frequency of the N34S mutation of serine protease inhibitor Kazal type 1 (SPINK1) gene differs between patients with alcoholic chronic pancreatitis, patients with nonalcoholic chronic pancreatitis, alcoholics without any digestive organ damage, and controls. We also sought to investigate whether the frequency of this mutation differs between women and men, and whether the mutation is associated with the age of patients at first diagnosis of chronic pancreatitis.
The study included 207 patients: 67 with alcoholic chronic pancreatitis, 35 with nonalcoholic chronic pancreatitis, 43 alcoholics with no damage to digestive organs, and 62 healthy volunteers who served as controls. The N34S mutation of the SPINK1 gene was detected with the polymerase chain reaction.
The N34S mutation of the SPINK1 gene occurred in 15 of 207 patients (7.25%). The mutation was most frequent in patients with alcoholic chronic pancreatitis (10 patients, 16.39%) and was more frequent compared with the control group (2 patients, 3.23%) (P = 0.047). There were no statistically significant differences between the other groups: patients with nonalcoholic chronic pancreatitis (2 patients, 5.71%), alcoholics without digestive organ damage (1 patient, 2.33%), and controls. The mutation was more frequent in men than in women (P = 0.043). There were no differences between patients with and without the mutation in terms of the age at first diagnosis of chronic pancreatitis (P >0.05).
The N34S mutation of the SPINK1 gene seems to be significantly correlated with alcoholic chronic pancreatitis.

[Show abstract][Hide abstract] ABSTRACT: INTRODUCTION: Recent studies have implicated essential role of genetic factors in development of chronic panreatitis. OBJECTIVES: The aim of this study was to establish the frequency differences of the NS34 mutation of SPINK1 gene between patients with alcoholic chronic pancreatitis, nonalcoholic chronic pancreatitis, alcoholics without any digestive organ damage and controls. We wanted to find out if this mutation occurs with different frequency among males and females and if the mutations affects the age of chronic pancreatitis onset. PATIENTS AND METHODS: 207 patients were qualified for the study: 67 with alcoholic chronic pancreatitis, 35 with nonalcoholic chronic pancreatitis, 43 alcoholics with no damage to digestive organs and 62 healthy volunteers who were the control group. The NS34 mutation of SPINK1 gene was detected with polymerase chain reaction. RESULTS: In the study group of 207 patients the NS34 mutation of SPINK1 gene occurred in 15 patients (7.25% frequency). This mutation was the most frequent in the group with alcoholic chronic pancreatitis (10 patients, 16.39%) and was more frequent in comparison to the control group (2 patients, 3.23%) (p=0.047), differences between other groups: nonalcoholic chronic pancreatitis (2 patients, 5.71%), alcoholics without any digestive organ damage (1 patient, 2.33%) and controls- were statistically insignificant. This mutation was more frequent in males than females (p=0.043). The age of chronic pancreatitis onset was not different between the groups of patients with the NS34 mutation of SPINK1 gene and without it (p>0.05). CONCLUSIONS: The NS34 mutation of SPINK1 gene seems to be significantly correlated with alcoholic chronic pancreatitis.

[Show abstract][Hide abstract] ABSTRACT: Alpha-fetoprotein (AFP) is a tumor marker used in clinical diagnosis and for monitoring the course of treatment. Serum concentration of AFP in excess of several hundred ng/ml is nearly 100 percent positive predictive value for hepatocellular carcinoma. The aim of this study was evaluation of AFP serum concentration in patients with different chronic liver diseases and the relationship between the concentration of AFP and gender in the studied groups of patients.
The study includes 359 patients: 72 with autoimmune hepatitis, 27 with cancer metastatic to the liver, 53 with nonalcoholic fatty liver disease, 207 with liver cirrhosis and 40 healthy volunteers as control group. The concentration of AFP was examined in all patients.
The highest AFP concentration occurred in the patients with autoimmune hepatitis, with metastatic liver cancer and with liver cirrhosis 16.81 +/- 5.49 ng/ml, 9.67 +/- 1.48 ng/ml i 8.42 +/- 2.73 ng/ml (p < 0.001 compared to the control group) respectively. Considering the classification of cirrhosis according to Child-Pugh Score the mean concentrations of AFP were: in Class A - 7.03 +/- 2.29 ng/ml, B - 7.59 +/- 2.45 ng/ml i C - 10.02 +/- 2.40 ng/ml. There were no statistically significant differences in the mean AFP concentrations between the patients with nonalcoholic fatty liver disease and the control group. Also showed no differences in the average concentration of AFP in men and women in study groups of patients (p > 0.05).
Elevated serum AFP concentration typically up to several ng/ml is observed in autoimmune hepatitis, metastatic liver cancer and liver cirrhosis. Concentration of AFP correlates with the severity of liver cirrhosis. Simple steatosis of liver as one of the forms of nonalcoholic fatty liver disease is characterized by normal serum concentration of AFP. No relationship between AFP concentration and gender in patients with chronic liver disease is observed.

[Show abstract][Hide abstract] ABSTRACT: To assess the prevalence of spontaneous bacterial peritonitis (SBP) in asymptomatic patients with decompensated liver cirrhosis.
Patients (pts) with symptoms of decompensation of liver cirrhosis, ascites, and no signs indicating SBP were included to our study. Exclusion criteria include: 1/ clinical symptoms of infection, 2/ developing de novo or worsening hepatic encephalopathy, 3/ gastrointestinal bleeding within the last month, 4/ renal failure, 5/ antibiotic treatment or norfloxacin prophylaxis at admission. About 60 ml of ascitic fluid were drawn for lab examination. Pathologic assessment for atypical cells was also performed.
37 patients fulfilled inclusion criteria. Their mean age was 56.2 ± 12.1. The Child-Pugh classification revealed 13 (35.1%) patients of class B and 24 (64.9%) patients of class C. The mean Model for End-Stage Liver Disease score in this group was 16.6 ± 6.8. The mean ascitic protein content was 1.85 ± 1.09 g/dL and mean neutrophil count 144.8 ± 445.1/mm3. Ascitic fluid analysis revealed: signs of bacterascites in 6 of 37 (16.2%) pts; neutrocytic ascites in 1 of 37 (2.7%) pts; and 2 of 37 (5.4%) pts met criteria for SBP. C-reactive protein level was the best predictor of infection [SBP(+) 47.9 ± 40.9 versus SBP(-) 11.7 ± 5.1; p= 0.0005].
The prevalence of SBP in asymptomatic cirrhotics with ascites is low. We observed the trend towards more frequent occurrence of the infection in patients suffered from severe liver disease (Child-Pugh C group).

[Show abstract][Hide abstract] ABSTRACT: Alcohol dependence poses a serious medical and sociological problem. It is influenced by multiple environmental and genetic factors, which may determine differences in alcohol metabolism. Genetic polymorphism of the enzymes involved in alcohol metabolism is highly ethnically and race dependent. The purpose of this study was to investigate the differences, if present, in the allele and genotype frequency of alcohol dehydrogenase 1B (ADH1B), ADH1C and the microsomal ethanol-oxidizing system (MEOS/CYP2E1) between alcohol-dependent individuals and controls and also to determine if these genotypes cause a difference in the age at which the patients become alcohol dependent. The allele and genotype frequencies of ADH1B, ADH1C, and CYP2E1 were determined in 204 alcohol dependent men and 172 healthy volunteers who do not drink alcohol (control group). Genotyping was performed by PCR-RFLP methods on white cell DNA. ADH1B*1 (99.3%) and ADH1C*1 (62.5%) alleles and ADH1B*1/*1 (N = 201) and ADH1C*1/*1 (N = 85) genotypes were statistically more frequent among alcohol-dependent subjects than among controls (99.3 and 62.5%, N = 201 and 85 vs 94.5 and 40.7%, N = 153 and 32, respectively). Differences in the CYP2E1 allele and genotype distribution between groups were not significant. The persons with ADH1C*1/*1 and CYP2E1*c1/*c2 genotypes became alcohol dependent at a considerably younger age than the subjects with ADH1C*1/*2, ADH1C*2/*2 and CYP2E1*c1/*c1 genotypes (28.08, 25.67 years vs 36.0, 45.05, 34.45 years, respectively). In the Polish men examined, ADH1C*1 and ADH1B*1 alleles and ADH1C*1/*1 and ADH1B*1/*1 genotypes favor alcohol dependence. The ADH1B*2 allele may protect from alcohol dependence. However, subjects with ADH1C*1/*1 and CYP2E1*c1/*c2 genotypes become alcohol dependent at a considerably younger age than the subjects with ADH1C*1/*2, ADH1C*2/*2 and CYP2E1*c1/*c1 genotypes.

[Show abstract][Hide abstract] ABSTRACT: Introduction: Over recent years, a number of studies on complex, however still elusive pathogenesis of inflammatory bowel disease (IBD) has been conducted. In order to perform a more detailed analysis and due to the restricted system of human models, in the ongoing studies scientists use an animal experimental model for colitis. Inflammation of large intestine induced by rectal administration of TNBS or by DSS given in potable water is among most common models of colitis described in available literature. Aim of the study: The aim of this paper was the comparison of two most common experimental models of colitis prosperously applied for determining new methods for control of IBD pathogenesis. Material and methods: The studies were conducted on Wistar rats. In one group of rats inflammation was induced by a single rectal administration of TNBS at the dose of 10 mg diluted in 50% ethanol up to the volume of 0.25 ml. In the other group of rats DSS was administrated in potable water at the concentration of 1.5 % through the period of 7 days. Animals were weighted before and after the experiment. Intestines affected with inflammation were sampled from both groups for histopathological examination. The level of IL-1β, IL-6, IL-10, and TNF-α and MPO was determined in serum and intestinal homogenate using ELISA immune-enzymatic test. Results and conclusions: The model of acute colitis based on the administration of DSS in drinking water was found to cause more intensive inflammation than the TNBS-based model and consequently resulted in a more significant loss of weight in the animals and yielded stronger inflammatory infiltrations. Histopathological examination revealed slightly more extended inflammatory hallmarks with more intensified edema of mucosa and submucosa in the DSS-based model. No difference regarding the levels of cytokines such as: IL-1β, IL-6, IL-10, TNF-α was reported between the two compared models.
[Show abstract][Hide abstract] ABSTRACT: Alcoholic liver disease is a major health consequence of chronic ethanol consumption. The mechanisms by which alcohol promotes development of ALD are still not completely clear. Recent findings indicate that alcohol-related increased gut permeability may trigger the inflammatory cascade and play a crucial role in the onset and progression of this disease. Endotoxins are lipopolysaccharides (LPS) derived from the cell wall of Gram-negative bacteria. Chronic alcohol exposure may increase their penetration from the gut into the portal blood and their concentration in the liver. LPS/endotoxin recognition by Toll-like receptor 4 (TLR4) on Kupffer cells and activation of liver macrophages result in elevated synthesis of inflammatory cytokines, chemokines and reactive oxygen species (ROS). These events further account for recruitment of lymphocytes and neutrophils to the liver and promote inflammatory responses that seem to be critical in the development of alcoholic liver disease. In this review we highlight and discuss the mechanisms of alcohol- mediated alterations of intestinal barrier function as well as endothoxin-induced liver tissue injury.
[Show abstract][Hide abstract] ABSTRACT: The toxicity of non-steroidal anti-inflammatory drugs (NSAIDs) related to the upper gastrointestinal (GI) tract is well established. However, they may cause injury distal to the duodenum as well - to the small and large intestine and/or to other organs of the digestive system. Non-steroidal anti-inflammatory drugs induce small intestinal perforation, ulcers or strictures requiring surgery and inflammation with blood and protein loss called NSAID enteropathy. These drugs can exacerbate pre-existing large bowel disease (e.g. ulcerative colitis, diverticular disease) and precipitate relapse of inactive disease or the new onset of inflammatory bowel disease (IBD) with rapid resolution of symptoms on their withdrawal. They have been implicated in the development of microscopic colitis. Non-steroidal anti-inflammatory drugs-associated toxicity of the small and large bowel is increasingly recognized in clinical practice, as enteroscopic procedures become more frequently used. Liver injury is an uncommon, but potentially lethal complication. It can occur with all NSAIDs, but diclofenac and sulindac seem to be most commonly associated with the problem. These drugs may contribute to acute fatty liver of pregnancy. Hepatotoxicity is likely due to an idiosyncratic reaction resulting from an immunological response or altered metabolic pathways. The major benefits of NSAIDs relate to reports of possible prevention, delay or regression of progress towards cancer of the colon, oesophagus, stomach as well as of cancer of the breast, lung, prostate and skin. Despite their promise, NSAIDs are not yet recommended for prevention or treatment of any cancer, because the balance of hazards and benefits from the treatment must be resolved in the designated patient population.
[Show abstract][Hide abstract] ABSTRACT: Matrix metalloproteinase (MMP)-2 and -9 (gelatinases) participate in extracellular protein remodeling. Moreover, they are involved in the development of hepatic fibrosis. The goal of this study was to evaluate liver gelatinase activities after erythropoietin (Epo) treatment (1U/dose, sc) in experimentally damaged livers of rats treated with D-galactosamine (Gal, 800 mg/kg/dose, ip). Sixty rats were divided into six equal groups: I - received 5 doses of Epo and a single dose of Gal [the experiment duration (ED): 10 days]; II - received 5 doses of Epo and 3 doses of Gal (ED: 14 days); III - received only 5 doses of Epo (ED: 9 days); IV - received 3 doses of Gal (ED: 5 days);V - received a single dose of Gal (ED: 1 day); VI - control group (ED: 9 days). The animals were sacrificed and the livers were collected 48 h after the last drug administration. The activity of gelatinases was measured using gelatin zymography. No fluctuations in gelatinase activities were observed after the administration of a single dose of Gal in comparison to the control group. However, a significant increase in gelatinase activities was observed after treatment with three doses of Gal. Five doses of Epo administrated before Gal treatment prevented elevated gelatinase activities: MMP-9 activity was comparable to control, and MMP-2 activity was decreased (group II). The gelatinase activities was lower in group I and II in comparison to the control group. These results revealed that Epo decreases MMP-2 and MMP-9 activity, suggesting that it is a hepatoprotective agent against hepatic damage induced by galactosamine injection.
[Show abstract][Hide abstract] ABSTRACT: The purpose of this experiment was to investigate the role of PPAR ligands in the course of inflammation and of rosiglitazone, a PPAR-gamma-specific agonist, on the course of experimental acute pancreatitis (EAP).
EAP was induced by administration of 5% sodium taurocholate injected into the pancreatic duct. The inflammatory activity was evaluated by biochemical scores (alpha-amylase, lipase, aminotransferases, and bilirubin), morphological changes (determined by light microscopy, H+E stained), and immunohistochemical reactions (ICAM, nitrotyrosine).
Rosilgitazone administered in the course of EAP at a dose 50 mg/kg p.o. decreased the intensity of morphological changes (edema, inflammatory infiltrates, necrosis, and erythrocyte extravasations). In the rosiglitazone-treated animals all the biochemical parameters of EAP were statistically significantly decreased. Immunohistochemical reactions against ICAM-1 and nitrotyrosine showed that rosiglitazone decreased the intensity of inflammatory reactions in the groups of treated animals.
PPAR-gamma agonists modulate the course of the inflammatory reaction. The administration of rosiglitazone decreased the intensity of the inflammatory process in the course of sodium taurocholate-induced EAP.

[Show abstract][Hide abstract] ABSTRACT: In gastroenterology non-variceal upper gastrointestinal bleeding is health hazard. Frequency of occurrence accounts for 40-150 cases per 100000 inhabitants with death rate of 7-14%. Researches which goal is to improve treatment effectiveness as well as to establish standardized procedures for managing patients with symptoms of non-variceal upper gastrointestinal bleeding; have been conducted since many years. At the moment of admission, designed standards enable appropriate elaboration of patients' health state, referral to the right clinic and implementation of the most accurate treatment methods. Increase of suppression of primary bleeding as well as prevention of recurrence is associated with dynamic development of endoscopic treatment methods as well as with optimization of pharmacological treatment. In significant percentage, efficiency of non - variceal bleedings treatment depends on clinic's character (availability of equipment, experience of personnel) and on cooperation between several specialists (including gastroenterologist, surgeon, anesthetist, operative radiologist). Aim of the work is to present the latest evaluation of the mentioned subject, based on accessible literature. This work includes the basic principles for determination of bleeding intensity and risk of its recurrence as well as directions referring to fluids resuscitation and to monitoring of patients. Information on currently applied endoscopic methods for inhibition of non variceal upper gastrointestinal bleeding (injection, mechanical and thermo-coagulation techniques), comparison of their efficiency and possibility of application is provided in the work. The paper work also presents the newest directives for pharmacological treatment and guidelines for possible surgical treatment.
