Aim To investigate prognostic significance of preoperative levels of the Carbohydrate anti-gen 19-9 (CA 19-9) in patients with stage III rectal adenocarcinoma who underwent a treatment at the Clinical Centre of the University of Sarajevo. Materials A retrospective cohort study included 84 patients who underwent radical anterior rectal resection due to grade III rectal adenocarcinoma, followed by adjuvant chemotherapy according to the FOLFOX protocol (Oxaliplatin, Leucovorin, 5-Fluorouracil (5-FU)). The patients were divided into two groups according to CA 19-9 values (≥27 U/mL and <27 U/mL, respectively). Results High pre-operative CA 19-9 values predicted an increased probability of postoperative metastases, especially liver, lung and abdominopelvic metastases, as well as three-year disease-free survival (3Y-DFS) and three-year overall survival (3Y-OS). The 3Y-DFS rate for patients with high CA 19-9 was 64.5%, while for those with low CA 19-9 it was 87.2%. The 3Y-OS rate for patients with high CA 19-9 was 89.8%, while for those with low CA 19-9 it was 65.7%. Univariate and multivariate regression analysis confirmed that a high level of CA 19-9 is an independent predictor for DFS and OS shorter than three years. Conclusion Pre-operatively elevated values of CA 19-9 in rectal adenocarcinoma have a significant role in predicting the outcome in patients with stage III rectal adenocarcinoma.

Abstract: Surgical correction of inguinal hernias is the most commonly used surgical procedure in the world. Currently only three surgical techniques have been validated, that is the Shouldice technique, the Lichtenstein technique, and laparoscopic techniques such as transabdominal preperitoneal (TAPP) hernioplasty and totally extraperitoneal endoscopic hernioplasty (TEP).The aim of the study: The aim of this study is to show the results in terms of postoperative recovery, complications, length of hospitalization after inguinal hernia surgery in patients who underwent the Lichtenstein and the laparoscopic (TAPP) methods.Material and methods: This is a monocentric, retrospective cohort study, conducted in the period from 2019 to 2023. The research period covered 70 patients who underwent surgery at the Clinic for General and Abdominal Surgery with Glandular Surgery, of the University Clinical Center, Sarajevo. The patients were divided into two groups: Group 1: 20 patients who underwent the TAPP method and Group 2: 50 patients who underwent the Lichtenstein method. All patients underwent surgery performed by two doctors.Results: One woman (1.4%) and 69 men (98.6%) participated in the research. Of the total number, 50 patients (72.5%) were treated with the Lichtenstein technique, and 19 (27.5%) were treated with the TAPP technique (p=0.539). The statistical results did not show a significant difference in the average age between patients who underwent the Lichtenstein and the TAPP technique (T=0.759; p=0.450).Discussion: There was no significant difference in relation to age and type of surgery (T=0.759; p=0.450). There was no statistical difference in the choice of surgical approach in relation to the laterality of the hernia (P<0.001), nor any statistically significant difference between the TAPP and Lichtenstein surgical procedures in relation to BMI T=0.613; p=0.542. Our analyses showed that patients treated with the TAPP technique had a statisticallysignificantly higher probability of shorter postoperative hospitalization compared to those treated with the Lichtenstein technique (B=0.245; p=0.019). Two patients in the study had complications within 30 days (Clavien-Dindo Grade I and Grade IIIB).Conclusion: Using an individual approach for each patient, surgical treatment of hernia using laparoscopic TAPP can be the first choice in patients without comorbidities, without previous pelvic surgery, bilaterality or recurrence of previous surgery (anterior approach). Patients treated with the laparoscopic technique (TAPP) have a shorter hospitalization time, which ultimately affects the economic aspect.

Background: Difficult cholecystectomy, often associated with a heightened risk of complications, poses a significant surgical dilemma. Risk factors, such as patient age, increased body weight, the presence of gallstones, acute cholecystitis, and prior abdominal surgeries, can complicate laparoscopic cholecystectomy and necessitate conver- sion to an open procedure for safety. The aim of our study was to assess the applicability of the Nassar scale in predicting the need for conversion from laparoscopic to open cholecystectomy.Material and methods: In our prospective cohort study, we included 85 patients who underwent either emergency or elective laparoscopic cholecystectomy between December 2021 and October 2023. The Nassar scale was used to assess the complexity of laparoscopic cholecystectomy, incorporating parameters such as ‘Gallbladder,’ ‘Cystic pedicle,’and ‘Adhesions’ to determine a final score ranging from 1 to 5. Statistical analysis involved descriptive and analytical methods, with the significance threshold set at p < 0.05.Results: ANOVA analysis revealed a statistically significant difference in the duration of operative procedures with different Nassar grades (p < 0.001). An increase in the Nassar grade by 1 was associated with a statistically significant6.23-fold increase in the odds of conversion to an open procedure (p < 0.001). Receiver Operating Characteristic (ROC) analysis demonstrated a highly significant association (p < 0.001) between the Nassar grade and the conversion event, with an Area Under the Curve (AUC) of 0.881 (95% CI 0.79,0.96). The optimal cutoff value, identified as >2.5, struck a balance between sensitivity (0.86) and 1-specificity (0.23). Conclusion: Our study underscores the utility of the Nassar scale in surgical practice. It provides valuable insights into assessing the severity of operations, facilitating informed decision-making, and optimizing treatment outcomes for patients undergoing laparoscopic cholecystectomy at our institution.

Background: Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer-related deaths worldwide. Studies often consider colon and rectal cancers together. The combination of CA 19-9 and CEA markers is used to improve diagnostic accuracy, but there are no reports on the use of this combination as a prognostic predictor for CRC. The study by Kamada et al. was the first to use the "tumor marker index" (TMI), the geometric mean of normalized CEA and CA 19-9 in CRC, demonstrating the prognostic capabilities of this novel marker. However, it is not known how the preoperative value of TMI compares and fits into the current system of prognostic factors for preoperative prediction of overall survival (OS) and disease-free survival (DFS). Objective: The aim was to investigate the significance of preoperatively determined TMI in predicting three-year overall survival (3Y-OS) and three-year disease-free survival (3Y-DFS) in patients with stage III adenocarcinoma of the upper and middle rectum. Methods: Our retrospective cohort study included 93 patients who underwent open anterior resection of the rectum between January 2015 and December 2020. Optimal cut-off values of the markers were determined by ROC analysis. Statistical analysis was performed using IBM SPSS Statistics 22 and R 4.4.0. Results: Patients with TMI ≥1.0158 had a statistically significantly higher likelihood of mortality within three years (p=0.012). Patients with TMI ≥0.979 had a statistically significantly higher likelihood of disease-free survival of less than three years (p=0.003). Compared to CEA and CA 19-9, TMI had the highest AUC for predicting 3Y-OS (0.740, p=0.020) and 3Y-DFS (0.780, p=0.012). Adding TMI to other predictors increased the AUC for predicting both 3Y-OS (from 0.748 to 0.853) (p=0.001) and 3Y-DFS (from 0.711 to 0.850) (p=0.001). Conclusion: Our study confirmed previous findings on the usefulness of preoperative TMI as a prognostic marker, further expanding knowledge about its accuracy by comparing and combining it with established prognostic factors, including CEA and CA 19-9.

Background: Radical surgical resection for pancreatic head carcinoma offers a chance for cure but unfortunately is only available to a limited number of patients. For a significant number of patients, palliative surgery remains the only option. The question of the most effective approach for patients with borderline resectable pancreatic head carcinoma (BRPHC) remains unresolved. Objective: The aim of the study was to compare the morbidity and mortality following R1 duodenocephalic pancreatectomy and double palliative bypass to explore the most optimal surgical treatment for patients with BRPHC. Methods: Our retrospective cohort study included 64 patients with BRPHC who underwent surgery from 2012 to 2019, with postoperative follow-up for three years. Morbidity and mortality parameters were examined based on the type of surgical treatment: R1 duodenocephalic pancreatectomy or palliative double bypass. Chi-square test, univariate regression, and Kaplan-Meier analysis were used as basic statistical methods in the analysis of the results. Results: Patients undergoing R1 duodenocephalic pancreatectomy had a 3.69 times higher risk of developing biliary leak (p=0.039; 95%CI:1.066, 1.181) and shorter survival compared to those undergoing palliative double bypass (p=0.022). No statistically significant association was found between the type of surgical procedure and other postoperative complications. Conclusion: Our study suggests that the double palliative bypass procedure may be a better option than R1 resection for patients with BRPHC.

Introduction: Tumors of Fallopian tubes are rare in general, and they are the rarest tumors of female genital tract. According to clasification of World health organisation (WHO), papillomas, cystadenoma, adenofibroma, cystadenofibroma (CAF), metaplastic papillary tumors and endometrioid polyps belong to group of benign tumors. Serous papillary cystadenofibroma (SPCAF) is rare tumor and it is ususally located on fimbrial end of the tube and it is considered that it has „Müllerian“ origin. Aim: The aim of this article is to show a rare case of cystadenofibroma of Fallopian tube which was found as random sample during histopathological analysis of specimen which was extracted during laparatomy due to the large tumor mass in abdomen. Case report: A 43-year-old patient underwent surgery for a large tumor mass in the abdomen, unknown lesions and pathohistology, which was radiologically verified four years before hospitalization. We removed the specimen that made up the tumor, along with the uterus and adnexes, weighing 14 kg and sent for histopatology. A large tumor mass is made up of a giant uterine myoma, and in the analysis of the other preparation, in addition to endometrial adenocarcinoma, there is also a rare Fallopian tube cystadenofibroma. On the sixth day of hospitalization, the patient is discharged home. At control after three months, the patient was without problems, with ongoing adjuvant brachytherapy. Conclusion: Improvement of prevention measures and work on the continuing education of patients and physicians at the primary care level are needed to ensure that patients receive the best treatment in a timely manner. Cystadenofibroma is a rare tumor in general and gynecologic oncology, and as authors it is a great honor for us to contribute to the world literature and to present the twentieth case of this tumor.

Introduction: Colorectal cancer is the third most common cancer in the male and female population. Surgical treatment of colorectal cancer is based on tumor resection and removal of associated lymph glands. Aim: The aim of the paper is to present data from a five-year retrospective study of the surgical treatment of colorectal cancer at the Clinic for General and Abdominal Surgery at the Clinical Center of the University of Sarajevo. Methods: This is a retrospective five-year clinical trial (2014-2018) of patients with and surgically treated for colorectal cancer at the Clinic for General and Abdominal Surgery at the Clinical Center of Sarajevo University. Results: In the 2014-2018 period, n = 11 172 patients were hospitalized at the Clinic, of which n = 732 were surgically treated for colorectal cancer. 69.80% were operated in an elective program. 30.20% were made as emergencies. 51.09% were male patients and 48.36% were female patients. 97.20% were made by open technique. 2.10% operated by minimally invasive procedure. the most common type of colon tumor is Adenocarcinomas are the most common with 79%. Conclusions: Better prevention and early detection are required to reduce the incidence of patients, which ultimately leads to more effective treatment and longer survival of colon cancer patients. Operative surgical principles must be adapted to modern trends, minimally invasive procedures (laparoscopic surgery, robotic surgery).

Introduction: Breast cancer and its treatment change the perception of mastectomized women of their physical appearance, which leads to depression and has a negative effect on the overall quality of life of those woman. Aim: We wanted to assess the quality of life and the degree of depression of patients suffering from breast cancer, on the basis of a standardised questionnaire to assess the patients’ quality of life (QLQ-C-30 BR-23), and the degree of depression using Beck’s Depression Inventory (BDI, II). Materials and Methods: The research was conducted on a sample of 160 patients, who were surveyed before and after the surgical procedure. The inclusion criteria for the research were: patients suffering from breast cancer aged between 18 and 70 years, cancer diagnosed by FNB or CORE biopsy. The patients were divided into two groups: patients having breast-conserving surgery and patients having radical surgical treatment. Results: There were 47 or 39.37% patients who underwent breast-conserving surgery and 113 or 70.62% patients who underwent radical surgery. The results of the survey conducted show that there was no difference in the quality of life of patients before and after surgery, regardless of the type of surgical procedure undertaken. However, there was a significant different in the degree of depression between patients subjected to different surgical procedures, where the patients surveyed post-surgery after radical mastectomy showed a higher degree of depression than the patients surveyed after breast-conserving surgery. Conclusion: There is no difference in the quality of life before and after surgery, regardless of the type of operation. However, there is a significant difference in the degree of depression in patients after radical mastectomy, who showed a higher degree of depression than the surveyed patients who underwent breast-conserving surgery.

Introduction: According to the World Health Organization estimates annually in the world die due to CVI every sixth women and 10th man. This paper is the research of the correlation between changes in relative air humidity and stroke (CVA) in the Sarajevo Canton. Included are patients who experienced an acute stroke in the Canton of Sarajevo and treated in the pre hospital phase by the staff of the Institute for Emergency Medicine. Days with stroke and those without cases of stroke were compared within three years and meteorological data for those days were obtained by the Weather Bureau of Federation of Bosnia and Herzegovina. Meteorological data include measurements of average humidity every day at 7, 14 and 21 o’clock in three years. Aim: To evaluate the significance of the influence of humidity on the incidence of CVI’s. Show the trend towards CVI in the reporting period and is it correlated with the trend of change in relative humidity in those days. Correlate the incidence of stroke as determined in relation to gender, age and selected climatic parameter. Material and Methods: This article presents a retrospective study. Subjects were patients of Emergency Medical Care Institute in Sarajevo, which in the period from 2004 to 2006 had a CVI. Included are patients who had a working diagnosis of stroke for the first time or as a repeated stroke. Analysis of cases of stroke was carried out by gender, age, days and seasons by descriptive-analytical epidemiological methods. Results: In total were registered 1930 patients during three years period. According to years of research in 2004–635, 2005-616 and 2006 – 679. It was found that when testing the null hypothesis about the effects of humidity in two months with a maximum stroke in the year and days without CVI and relative humidity only in 2005 had a statistically significant effect on the incidence of stroke, while during the other two years of the study there was no impacts. It turned out that the extreme values of relative humidity of the day whether there was a rapid increase or decrees in humidity increases the incidence of stroke in all three years of research. Conclusion: Patients gender had no effect on the incidence of CVI. Seasons had no effect on the incidence of CVI. Most CVI in all three years of research was in relation to the old age and occurred in the older age group 70-79 (41.35%), where it was shown that the age of the patient influences the incidence of CVI. Extremely low relative humidity and extremely high, influence on the increase in the number of CVI. Determined is a slight correlation between the average relative humidity and CVI in single day.
