Introduction:CEA and CA 19-9 are the most common tumor associated antigens used in the staging of patients with rectal cancer and other parts of the colon.Goal:of this study was to evaluate the value of CEA and CA 19-9 in serum of patients with colon cancer and prove its place in the diagnostic staging.Material and Methods:The study was retrospective-prospective performed at the Gastroenterohepatology Clinic, Clinical Center of Sarajevo University. The study included 91 hospitalized patients who had histologically confirmed diagnosis of colon adenocarcinoma in 98% of cases. All patients underwent colonoscopy, targeted biopsy and measurement of CEA and CA 19-9 levels in serum. All of them underwent abdominal CT and MRI of the pelvis in case of rectal cancer.Results:The study analyzed 58 men and 33 women, mean age 66.6 years, with the youngest patient at age of 35 and the oldest at age of 89 years. The largest number of patients was aged 56-75 years. According to localization 77 patients had carcinoma located in the area of the rectum and sigma 37.4 and 37.4 in the rectostigmoid area and sigma. Metastases were observed in 37 patients, with predominance in the liver (22 cases) and both liver and lungs (5 cases). CEA and CA 19-9 were determined in all cases but patients with metastases had high values, especially in the two cases of cecoascendent colon cancer where detected values were extremely high (1789ng/ml and 10780U/ml). Values of CA19 -9 were significantly higher (p<0.05). CEA mean values were highest in patients aged over 75 years. In case of CA 19-9 high mean values have been recorded in patients aged over 75 years with statistically significant differences between the age groups (p<0.05).Conclusion:CEA and CA19-9 are cancer antigens that are late markers of carcinogenesis, with significantly elevated serum concentrations in case of colon cancer with already developed metastases. Older age group of patient has significantly elevated levels of both antigens. Cancer was twice more common in men than in women.

Background/Aims: Sedation rates may vary among countries, depending on patients’ and endoscopists’ preferences. The aim of this survey was to investigate the rate of using premedication for routine diagnostic upper gastrointestinal (UGI) endoscopy in endoscopy societies, members of the European Society of Gastrointestinal Endoscopy (ESGE). Methods: We evaluated a multiple-choice questionnaire which was e-mailed to representatives of national endoscopy societies, which are members of the ESGE. The questionnaire had 14 items referring to endoscopy practices in each country and the representatives’ endoscopy units. Results: The response rate was 76% (34/45). In 47% of the countries, less than 25% of patients undergo routine diagnostic UGI endoscopy with conscious sedation. In 62% of the responders’ endoscopy units, patients are not asked their preference for sedation and do not sign a consent form (59%). Common sedatives in use are midazolam (82%), diazepam (38%) or propofol (47%). Monitoring equipment is not available ‘in most of the endoscopy units’ in 46% (13/28) of the countries. Though they were available in 91% of the national representatives’ endoscopy units, they are rarely (21%) used to monitor unsedated routine diagnostic UGI endoscopy. Conclusions: In about 50% of ESGE-related countries, less than 25% of patients are sedated for routine diagnostic UGI endoscopy. Major issues to improve include availability of monitoring equipment and the use of a consent form.

Goal:The aim of the study is to define the MRI appearance of disorder in the Junctional zone (JZ) in women with adenomyosis compared to those without it, given the importance of the JZ in the regulation of various reproductive events.Materials and methods:This was a prospective, comparative and open study. Patients with adenomyosis have been sorted in target group, n = 82, while the control group consisted of patients without adenomyosis, n = 82. All patients, from both groups have undergone a magnetic resonance imaging of the pelvis. Using a software tool for measurement, the thickness of the JZ was measured in T2w sag sequences in all patients from both groups (target and control) n = 164. Patients in the target group type adenomyosis were assessed and categorized either as: diffuse, focal, or Adenomyoma and the results were compared. The presence of endometriosis and myomas in both groups was evaluated and its coexistence with adenomyosis was analyzed as well.Results:Of the 82 patients in the target group, 81.7% of the patients had diffuse adenomyosis, while 18.3% had focal type with statistically significant difference (p <0.05). The results of the Mann-Whitney U test showed that p <0.05, implying that there is a statistically significant difference in the thickness of the JZ between the control and target group, therefore patients from the target group with adenomyosis had a statistically significantly thicker junctional zone than the patients in the control group. The JZ in the target group was on average M = 14,3mm, SD = 1.3mm, while the thickness of JZ in the control group without adenomyosis was M = 5,6mm, SD = 1,3. Chi-square shows that p <0.05, implying that there is a statistically significant difference in the number of patients with myomas between the two groups, where the myomas significantly over-represented in the target group with 32,9 % vs.6 %).Conclusion:MRI is the method of choice for imaging and evaluation of JZ as an important diagnostic marker in the diagnosis of adenomyosis. It is important to recognize this condition as early as possible and distinguish it from other pathologies in order for timely and appropriate treatment.

Introduction: Upper gastrointestinal bleeding can be a life-threatening condition and requires careful evaluation from the very first episode in order to reduce the risk of rebleeding, hemorrhagic shock and death. The outcome of a patient with upper gastrointestinal bleeding depends on resuscitation measures taken during admission to the hospital and an adequate assessment of the patient’s risk level. Aim: The aim of the study is to compare Glasgow Blatchford score and Rockall score and to identify the most accurate score used in predicting unfavorable outcomes and the need for intervention. Methods: This study involves 237 patients with upper gastrointestinal bleeding. The accuracy of the scoring systems was assessed by plotting receiver-operating characteristic curves (ROC curves) and was calculated for GBS and RS with 95% confidence interval (CI). Results: As for mortality prediction, RS was superior to GBS (AUC 0.806 vs. 0.750). The GBS had a higher accuracy in detecting patients who needed transfusion units and was superior to the RS (AUC 0.810 vs.0.675). In predicting the need for intervention, RS was superior to GBS (AUC 0.707 vs. 0.636. Conclusion: GBS and RS are developed to help clinicians to triage patients appropriately in order to assess endoscopic therapy within a suitable time frame, as well as identify low risk patients for possible outpatient management. High accuracy of the GBS in predicting a need for transfusion represents an important endpoint to assess. RS was superior to GBS in predicting a need for intervention as well as mortality. Currently, a combination of these scoring systems is the best way for proper assessment.

BACKGROUND:AFP serum levels are considered as diagnostic and specific for hepatocellular carcinoma (HCC) in patients with liver cirrhosis (LC).AIM:This study aimed to examine the diagnostic value of AFP in the distinguishing of patients with HCC from patients with LC, and to analyse the potential correlation between AFP levels and liver disease stages.MATERIAL AND METHODS:Fifty patients with LC and fifty patients with HCC were included in this study. The majority of the patients were males, while the HBV aetiology was dominant.RESULTS:Significant differences between LC and HCC patients were detected for AST, ALT, GGT, bilirubin, AFP and AP. Patients with HCC had higher AFP values compared to LC. There was no significant correlation between the size of the tumour lesion and serum AFP levels. A positive correlation between AFP concentration and GGT activity was determined, as was the negative correlation between AFP and age of the subjects. The AFP value of 23.34 ng/m showed high sensitivity (84%) and specificity (82%).CONCLUSION:The size of the surface below the ROC curve (AUC) was 0.877 (0.80-0.95), which makes AFP a good biomarker and this diagnostic test is sufficient to separate patients with HCC and LC.

Background:Various complications occur in patients with advanced stages of liver diseases. Renal dysfunction, a parameter included in the MELD score, is the most important prognostic factor. There is a strong need in clinical practice to estimate the GFR in this patients.Objectives:The aim of our study was to detect differences in renal function among patients with different stages of chronic liver diseases caused by HBV and HCV, also to determine the impact of viral etiology and gender on the values of eGFR and renal function.Patients and Methods:This was an observational cross-sectional study performed on patients with HBV and HCV chronic hepatitis, cirrhosis and HCC caused by these viruses hospitalized during period 2009–2014 in the Clinic of Gastroenterohepatology, Clinical Center University of Sarajevo. The estimated GFR (eGFR) was evaluated by the MDRD4 method. For the processing of data SPSS 21.0 statistical software was used. Statistical methods used in this study where: analysis of variance test (ANOVA test), Student’s t-test for independent samples and Pearson coefficient of correlation. The level of significance was p <0.05.Results:Among this three groups of patients there was a statistically significant difference in eGFR (F= 18.79, p<0.05), i.e. increase of degree of liver damage was related with increase of renal impairment, as reflected by a significant reduction in estimated glomerular filtration rate. Gender had no significant effect on eGFR and renal function (p>0.05), except in group of patients with HCC (p<0.05). Etiology had no significant effect on eGFR and renal (p>0.05). There was statistically significant inverse correlation between glomerular filtration rate and liver enzymes AST (-.184) and GGT (-.181).Conclusions:By calculation of GFR, we determined the existence of a significant reduction of kidney function through progression of liver damage from HBV and HCV chronic hepatitis, liver cirrhosis to HCC caused by these viruses, which drawing attention to the importance of the assessment of renal function in patients with this liver pathologies. Gender and etiology had no significant effect on eGFR and impairment of renal function. Given the statistically significant inverse correlation between eGFR and AST and GGT this liver enzymes may have important role as marker for both renal and hepatic injury.
