Abstract
BACKGROUND/AIM Gallbladder cancer is a rare malignancy with a very high mortality, usually due to diagnosis in an advanced stage of the disease. Therefore, the aim of this study was to evaluate the clinical significance of cancer/testis antigen 1A (CTAG1A, NY-ESO1) and CD274 molecule (PD-L1, the ligand for programmed cell death protein 1) and their impact on the overall survival of patients with gallbladder cancer. PATIENTS AND METHODS Using immunohistochemical staining, we determined the expression of NY-ESO1 in tumor cells (positivity: cytoplasmic/nuclear staining of any intensity in ≥50%) and PD-L1 in tumor cells and intratumoral immune cells (positivity: cytoplasmic/membranous staining of any intensity in ≥1%). RESULTS The median overall survival (OS) of 58 patients with gallbladder cancer in our cohort was 7 months, and depended on the clinical stage of the disease; the 5-year OS rate was 10%. NY-ESO1 was expressed in 69.1% of cases. Immune cells were PD-L1-positive in 36.4% of cases, while tumor cells expressed PD-L1 in only 10.9% of cases. In six cases (10.9%), neither of the studied proteins were expressed. NY-ESO1 expression was negatively correlated with PD-L1 expression in immune cells (p=0.021). NY-ESO1 showed no correlation with any clinicopathological parameters or OS. PD-L1 expression in immune cells was significantly higher in tumors with perineural invasion (rs=0.318; p=0.018) and higher clinical disease stage (rs=0.339; p=0.013) but showed no correlation with OS. CONCLUSION Patients whose gallbladder cancer expresses NY-ESO1 or PD-L1 might be candidates for immunotherapy.

Abstract
(1) Background: Chronic spontaneous urticaria (CSU) has been linked to the dysbiosis of the gut microbiota. Furthermore, various studies have highlighted the anti-inflammatory properties of short-chain fatty acids (SCFAs), whose production is primarily regulated by the gut microbiota. However, only a few studies have investigated the role of major SCFA producers, such as Lachnospiraceae, in skin inflammatory diseases. (2) Goal: This study aimed to compare the abundance of Lachnospiraceae between CSU patients and healthy controls (HCs). (3) Material and methods: In this case-control study, 16S rRNA sequencing was performed to compare the composition of the gut microbiome between 22 CSU patients and 23 HCs. (4) Results: Beta-diversity revealed significant clustering (p < 0.05) between the CSU patients and HCs. Alpha diversity in the CSU group was significantly decreased according to the Evenness index (p < 0.05). The linear discriminant analysis effect size (LEfSe) identified the significant depletion of the Lachnospiraceae family in CSU patients. (5) Conclusion: Our study revealed the dysbiosis of the gut microbiota in CSU patients, including decreased levels of Lachnospiraceae members, responsible for SCFA production, suggesting that SCFAs may contribute to immune dysfunction in the pathogenesis of CSU. We speculate that the modulation of SCFAs could serve as a prospective additional option in CSU treatment.

Abstract
BACKGROUND This research looks at the connection between psychological stress and the prevalence of hand eczema (HE) among physicians and dentists (surgeons, non-surgeons). METHODS This cross-sectional field study involved 185 participants: physicians (surgeons, non-surgeons), dentists (surgeons, non-surgeons) and controls. Hand lesions were examined using the Osnabrueck Hand Eczema Severity Index (OHSI), and participants answered the Nordic Occupational Skin Questionnaire (NOSQ) and Perceived Stress Scale (PSS). Patch tests were performed using commercial contact allergens. RESULTS The estimated prevalence of HE (self-reported) was 43.9% (physicians 44.6%; dentists 43.2%). HE was significantly more reported by surgeons than controls (p < 0.004; V = 0.288). Degrees of perceived stress (PSS) did not differ significantly between the groups, though physicians non-surgeons most exhibited high stress (50%), and physicians surgeons most exhibited low stress (22.5%). High stress was associated with 2.5 higher odds for self-reported HE (p = 0.008). Low stress was greater among physicians/dentists who did not report eczema (41.0% vs. 24.6%); moderate stress was more common among those who reported eczema (72.3% vs. 51.8%; p = 0.038; V = 0.210). CONCLUSIONS Since high stress levels may negatively influence physicians'/dentists' work and quality of life, measures to decrease stress could be introduced into the treatment of healthcare workers who are prone to it.

Abstract
In colorectal surgery, anastomotic leakage is a serious complication, leading to higher postoperative morbidity and mortality. The aim of this study was to evaluate the accuracy of serum and intraperitoneal C-reactive protein (CRP) in early diagnostics of anastomotic leakage on the first four postoperative days after colorectal surgery. From January to October 2019, fifty-nine patients with colorectal carcinoma were operated on, with formation of primary anastomosis. Anastomotic leakage was diagnosed in eight patients. Comparing the levels of serum and intraperitoneal CRP, our study showed that serum CRP was a better predictor of anastomotic leakage. Serum CRP levels lower than 121 mg/L on postoperative day 4 were predictive of good healing of anastomosis.

Abstract
BACKGROUND Hypofractionated post-prostatectomy radiotherapy is emerging practice, however with no randomized evidence so far to support it's use. Additionally, patients with persistent PSA after prostatectomy may have aggressive disease and respond less well on standard salvage treatment. Herein we report outcomes for conventionally fractionated (CFR) and hypofractionated radiotherapy (HFR) in patients with persistent postprostatectomy PSA who received salvage radiotherapy to prostate bed. METHODS Single institution retrospective chart review was performed after Institutional Review Board approval. Between May 2012 and December 2016, 147 patients received salvage postprostatectomy radiotherapy. PSA failure-free and metastasis-free survival were calculated using Kaplan-Meier method. Cox regression analysis was performed to test association of fractionation regimen and other clinical factors with treatment outcomes. Early and late toxicity was assessed using Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0. RESULTS Sixty-nine patients who had persistent PSA (≥ 0.1 ng/mL) after prostatectomy were identified. Median follow-up was 67 months (95% CI 58-106 months, range, 8-106 months). Thirty-six patients (52.2%) received CFR, 66 Gy in 33 fractions, 2 Gy per fraction, and 33 patients (47.8%) received HFR, 52.5 Gy in 20 fractions, 2.63 Gy per fraction. Forty-seven (68%) patients received androgen deprivation therapy (ADT). 5-year PSA failure- and metastasis-free survival rate was 56.9% and 76.9%, respectively. Thirty patients (43%) experienced biochemical failure after salvage radiotherapy and 16 patients (23%) experienced metastatic relapse. Nine patients (13%) developed metastatic castration-resistant disease and died of advanced prostate cancer. Median PSA failure-free survival was 72 months (95% CI; 41-72 months), while median metastasis-free survival was not reached. Patients in HFR group were more likely to experience shorter PSA failure-free survival when compared to CFR group (HR 2.2; 95% CI 1.0-4.6, p = 0.04). On univariate analysis, factors significantly associated with PSA failure-free survival were radiotherapy schedule (CFR vs HFR, HR 2.2, 95% CI 1.0-4.6, p = 0.04), first postoperative PSA (HR 1.02, 95% CI 1.0-1.04, p = 0.03), and concomitant ADT (HR 3.3, 95% CI 1.2-8.6, p = 0.02). On multivariate analysis, factors significantly associated with PSA failure-free survival were radiotherapy schedule (HR 3.04, 95% CI 1.37-6.74, p = 0.006) and concomitant ADT (HR 4.41, 95% CI 1.6-12.12, p = 0.004). On univariate analysis, factors significantly associated with metastasis-free survival were the first postoperative PSA (HR 1.07, 95% CI 1.03-1.12, p = 0.002), seminal vesicle involvement (HR 3.48, 95% CI 1.26-9.6,p = 0.02), extracapsular extension (HR 7.02, 95% CI 1.96-25.07, p = 0.003), and surgical margin status (HR 2.86, 95% CI 1.03-7.97, p = 0.04). The first postoperative PSA (HR 1.04, 95% CI 1.00-1.08, p = 0.02) and extracapsular extension (HR 4.24, 95% CI 1.08-16.55, p = 0.04) remained significantly associated with metastasis-free survival on multivariate analysis. Three patients in CFR arm (8%) experienced late genitourinary grade 3 toxicity. CONCLUSIONS In our experience, commonly used hypofractionated radiotherapy regimen was associated with lower biochemical control compared to standard fractionation in patients with persistent PSA receiving salvage radiotherapy. Reason for this might be lower biological dose in HFR compared to CFR group. However, this observation is limited due to baseline imbalances in ADT use, ADT duration and Grade Group distribution between two radiotherapy cohorts. In patients with persistent PSA post-prostatectomy, the first postoperative PSA is an independent risk factor for treatment failure. Additional studies are needed to corroborate our observations.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is one of the most severe complications after cephalic pancreaticoduodenectomy, with mortality as high as 30%. Risk scores may help predict the risk of POPF. Multiple external validations substantially improve generalized clinical acceptability of a scoring system. AIM The aim of this study was to externally validate previously described fistula risk score in the prediction of clinically relevant POPF. METHODS All patients who underwent pancreaticoduodenectomy for any indication during a 5-year period were prospectively analyzed. A total of 132 patients were analyzed. RESULTS Of the 132 patients, 44 (33.3%) developed pancreatic fistula, including 12.9% biochemical leaks, 7.6% grade B fistula, and 12.9% grade C fistula. Cut-off point of 4.5 was determined to best separate patients who developed clinically relevant POPF with area under curve of 78% (p = .00003). Sensitivity and specificity for the prediction of clinically relevant POPF with the cut-off value of 4.5 was 70.4 and 74.3%, respectively. Positive predictive value with cut-off value 4.5 was 57.8%, and negative predictive value was 83.4%. CONCLUSION Fistula risk score identified low risk patients with false negative rate of 16.6%. Further external validation studies on large cohorts of patients and with wide case-mix may enable additional refinements of the score model.

Abstract
BACKGROUND Pancreatic fistula after pancreaticoduodenectomy is one of the most severe complications with mortality rates as high as 45%, and the prediction of most severe form of fistula (grade C) is crucial for successful management of patients who are to undergo cephalic pancreatoduodenectomy. It has been found that the amount of abdominal fat may predict grade C postoperative pancreatic fistula. In this study, we analysed the value of retrorenal fat thickness in the prediction of grade C pancreatic fistula. METHODS A total of 140 patients who underwent pancreaticoduodenectomy were retrospectively analysed. Retrorenal fat thickness and intra-abdominal fat, expressed as total fat area, visceral fat area and subcutaneous fat area, were determined from computed tomography slices using the known range of attenuation values (-190 to -30). Blood loss, operating time, pancreatic texture and main pancreatic duct diameter as well as body mass index were also analysed. RESULTS Retrorenal fat thickness (P = 0.0004), duct diameter (P = 0.0008), subcutaneous fat area (P = 0.023) and total fat area (P = 0.014) were found to be significant predictors of grade C pancreatic fistula. CONCLUSION Although retrorenal fat tissue thickness may seem robust, it is a simple measure that can be used to predict the most severe grade of pancreatic fistula after pancreaticoduodenectomy.

Abstract
Pregnant women with preeclampsia experience significant hemodynamic changes which lead to an increased myocardial workload. In response to increased demands in pregnancy, the heart muscle responds with ventricular remodeling process which involves cardiac muscle hypertrophy. Opposed to occurrence of eccentric ventricular hypertrophy in normal pregnancy, myocardial remodeling in a form of concentric hypertrophy will occur in pregnant patients with preeclampsia. Increased myocardial workload is manifested by an increased troponin release. As process of troponin degradation continue, filtration of degradation fragment through glomerular membrane occur, raising the possibility of it's detection in urine. Degradation fragments of troponin molecules are estimated to be 20 kDa with preserved immunoreactivity to high-sensitivity assays. Some of the authors suggest that serum levels of cardiac troponin I might be elevated in patients with hypertension, as well as in preeclamptic pregnant women. It is to be expected that evaluation of severity of the myocardial damage in pregnant woman with preeclampsia may be performed by measuring levels of troponin in the urine using high-sensitivity assays. Designing of urine dipstick will help to detect an early phase of myocardial involvement in preeclamptic pregnancies.

Abstract
The aim of this study was to compare union time between two different nail designs for the treatment of humeral shaft fracture, i.e. antegrade interlocking intramedullary nail with and without additional interlocking neutralization screws. The retrospective study included 51 patients treated with antegrade humeral intramedullary nailing between January 2015 and December 2017. The inclusion criteria of the study were proximal and middle third humeral shaft fractures. Fifty-one patients met the inclusion criteria; 23 patients were treated with antegrade intramedullary nail with additional interlocking neutralization screws through fracture site (group A) and 28 patients were treated with antegrade intramedullary nail without additional interlocking neutralization screws (group B). Medical documentation and radiographic images taken preoperatively and postoperatively were reviewed. Radiological union was defined as cortical bridging of at least three of four cortices in two-plane radiographs, with disappearance of the fracture gap. There were no significant differences in union time between the groups (p>0.05). To our knowledge, this is the first report of antegrade interlocking humeral nailing with additional interlocking neutralization screws through fracture site. Hypothetical advantages of fracture gap reduction by additional interlocking neutralization screws to promote union were not confirmed by this first clinical trial.

Abstract
AIM To investigate whether duodenal lesions induced by major venous occlusions can be attenuated by BPC 157 regardless nitric oxide (NO) system involvement.
METHODS Male Wistar rats underwent superior anterior pancreaticoduodenal vein (SAPDV)-ligation and were treated with a bath at the ligated SAPDV site (BPC 157 10 μg, 10 ng/kg per 1 mL bath/rat; L-NAME 5 mg/kg per 1 mL bath/rat; L-arginine 100 mg/kg per 1 mL bath/rat, alone and/or together; or BPC 157 10 μg/kg instilled into the rat stomach, at 1 min ligation-time). We recorded the vessel presentation (filled/appearance or emptied/disappearance) between the 5 arcade vessels arising from the SAPDV on the ventral duodenum side, the inferior anterior pancreaticoduodenal vein (IAPDV) and superior mesenteric vein (SMV) as bypassing vascular pathway to document the duodenal lesions presentation; increased NO- and oxidative stress [malondialdehyde (MDA)]-levels in duodenum.
RESULTS Unlike the severe course in the SAPDV-ligated controls, after BPC 157 application, the rats exhibited strong attenuation of the mucosal lesions and serosal congestion, improved vessel presentation, increased interconnections, increased branching by more than 60% from the initial value, the IAPDV and SMV were not congested. Interestingly, after 5 min and 30 min of L-NAME and L-arginine treatment alone, decreased mucosal and serosal duodenal lesions were observed; their effect was worsened at 24 h, and no effect on the collateral vessels and branching was seen. Together, L-NAME+L-arginine antagonized each other’s response, and thus, there was an NO-related effect. With BPC 157, all SAPDV-ligated rats receiving L-NAME and/or L-arginine appeared similar to the rats treated with BPC 157 alone. Also, BPC 157 in SAPDV-ligated rats normalized levels of NO and MDA, two oxidative stress markers, in duodenal tissues.
CONCLUSION BPC 157, rapidly bypassing occlusion, rescued the original duodenal flow through IAPDV to SMV flow, an effect related to the NO system and reduction of free radical formation.

Abstract
- The aim of the study was to reevaluate the safety and feasibility of discharge 24 h after elective uncomplicated laparoscopic cholecystectomy. Since the introduction of laparoscopic cholecystectomy in our hospital, the minimum postoperative stay was considered to be two days based on surgeons' experience. The study included 337 operations performed by 21 surgeons during 2016 in the Sestre milosrdnice University Hospital Centre. Conversion to open technique and cases of acute cholecystitis were excluded, while 15 patients had insufficient postoperative data. The mean length of stay was 2.38 (range 1 to 6) postoperative days, median two postoperative days. Serious complications involving suspected drain bile leakage and postoperative hemorrhage occurred in two (0.59%) patients, both in the first 24 h following surgery. One patient required emergency laparotomy on the first postoperative day. Readmission rate was 1.2%. The postoperative minor complication rate was 42 of 337 (12.46%); these included wound infections, urinary tract infections, symptoms included in postcholecystectomy syndrome, etc. The onset of these complications was mostly after postoperative day 3. The data obtained suggest that discharge on the first postoperative day after elective uncomplicated laparoscopic cholecystectomy should be considered safe and can be practiced in our hospital.

Abstract
The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute upper gastrointestinal bleeding (UGIB) with special reference to peptic ulcer bleeding (PUB). The study included 2198 consecutive patients referred to our emergency department due to acute UGIB from January 2008 to December 2012. All patients underwent urgent upper GI endoscopy within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed-up. The cumulative incidence of UGIB was 126/100,000 in the 5-year period. Two out of five patients had a bleeding peptic ulcer; in total, 440 (52.3%) had bleeding gastric ulcer, 356 (42.3%) had bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers, and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomoses. PUB was more common in men. The mean patient age was 65.9 years. The majority of patients (57%) with PUB were taking agents that attenuate the cytoprotective function of gastric and duodenal mucosa. Rebleeding occurred in 77 (9.7%) patients and 47 (5.9%) patients required surgical intervention. The 30-day morality was 5.2% and 10% of patients died from uncontrolled bleeding and concomitant diseases. In conclusion, PUB is the main cause of UGIB, characterized by a significant rebleeding rate and mortality.

Abstract
The aim of the study was to assess diagnostic accuracy (sensitivity and specificity) of Fenyö-Lindberg and Teicher scores for distinguishing patients that need immediate surgical treatment from the others, in a female population from an urban setting. The study prospectively included 130 female patients admitted to the emergency department with abdominal pain indicating acute appendicitis. The scores and parameters of validity were calculated and compared to definitive diagnosis. For Fenyö-Lindberg score of -17 or less, 84.5% sensitivity, 55.6% specificity, 87.9% positive predictive value (PPV) and 48.4% negative predictive value (NPV) were recorded. For cut-off value greater or equal to -2, there was 59.2% sensitivity, 77.8% specificity, 91% PPV and 33.3% NPV. The Receiver Operating Characteristic (ROC) curve analysis of Fenyö-Lindberg score showed that the best single cut-off value for discriminating acute appendicitis in the study population was -15. For Teicher score, values greater than -3 yielded 89.3% sensitivity and 22.2% specificity, 81.4% PPV and 35.3% NPV. In conclusion, Fenyö-Lindberg score could be used as an additional tool to exclude appendicitis and avoid unnecessary appendectomies. Teicher score may help in recognizing patients with appendicitis. None of the two scores can indicate or decline appendectomy in all cases. Scoring systems may be useful for pointing to important clinical signs and symptoms in specific subpopulations.

Abstract
Surgical resection of pancreatic cancer offers the only chance for prolonged survival. Pancretic resections are technically challenging, and are accompanied by a substantial risk for postoperative complications, the most significant complication being a pancreatic fistula. Risk factors for development of pancreatic leakage are now well known, and several prophylactic pharmacological measures, as well as technical interventions have been suggested in prevention of pancreatic fistula. With better postoperative care and improved radiological interventions, most frequently complications can be managed conservatively. This review also attempts to address some of the controversies related to optimal management of the pancreatic remnant after pancreaticoduodenectomy.

Abstract
OBJECTIVE Despite significant improvement in survival of gastrointestinal stromal tumors (GIST) due to use of tyrosine kinase inhibitors, surgery still represents the important part of clinical management. The aim of our study was to retrospectively analyze prognosis of GIST depending on the success of surgical treatments and utilization of chemotherapy in transitional country with relatively limited resources. METHODS cohort of consecutive patients operated for GIST in tertiary medical center, within time frame 1999-2012. RESULTS 54 patients, in age range 20-85 years (63.3 ± 14.7), male to female ratio 28 (51.9%):26 (48.1%), respectively. Complete excision with clean resection margins (R0) was obtained in 44 (81.5%)of total patients i.e. 44/47 (93.6%) of localized GISTs. Mean follow up was 3.9 ± 3.3 years and 19 patients (35.2%) received imatinib. Rate of overall survival was 40 (74.1%), disease-free survival 31 (57.4%) and 20 (37.0%) experienced recidivism. Follow-up parameters showed significant difference in connection with utilization of imatinib, completeness of resection and existence of metastatic disease (all p < 0.05). ROC analyzes revealed critical value of Ki-67 > 9% as significant predictor of long-term mortality; sensitivity 64.3% [95%CI = 35.1-87.2]; specificity 75.0% [58.8-87.3]; (AUC = 0.693; p = 0.049). CONCLUSION Rate of complete resections in studied sample of patients from transitional background was overall peer comparable with reports from the developed countries. On the other hand, relatively dominant prognostic position of surgical treatments might be consequence of limited utilization of adjuvant treatment with tyrosine kinase inhibitors.

Abstract
Background Familial adenomatous polyposis (FAP) is an autosomal dominantly inherited syndrome characterized by the development of numerous polyps in the colon and rectum. If left untreated, the affected patients inevitably develop colon cancer by the age of 40 years. A resection of the colon (colectomy) or of the colon and rectum (proctocolectomy) is needed to minimize the risk of cancer. Case Presentation We report a case of FAP through three generations of a single family, in which the grandmother and granddaughter underwent total colectomy with ileoanal anastomosis and did not develop colon cancer, while the son underwent subtotal colectomy with ileorectal anastomosis and developed recurrent rectal cancer. Data regarding timely surgery, surveillance, and chemoprevention are discussed. Conclusion The FAP phenotype determines the type of treatment. In severe polyposis, proctocolectomy with ileoanal anastomosis seems to be the optimal method for minimizing the risk of cancer development. This case report advocates complete rectal removal, especially in cases of poor patient compliance with colonoscopic surveillance.

Abstract
Primary mesenteric liposarcomas are very rare, especially when they are of mixed histologic pattern. Patient prognosis is based upon the most aggressive histologic type of liposarcoma. A case is reported of a 77-year-old man with a history of slowly increasing abdominal volume over 3 years. The diagnosis of giant intra-abdominal mass suspect of liposarcoma was confirmed by computed tomography and ultrasound scans. The patient underwent resection of 24 tumor masses weighing together 23.5 kg. The microscopic diagnosis was mixed-type liposarcoma of the mesentery. Although this type of tumor is rare, tumor tissue should be thoroughly collected and analyzed on histologic examination to reach definitive diagnosis. Recognition of the underappreciated subtype of liposarcoma is important for proper prognosis and treatment of the patient. According to our knowledge, this is the largest size of mixed-type mesenteric liposarcoma described in the English literature.

Abstract
Arterio-enteric fistula is a rare, but potentially deadly cause of gastrointestinal bleeding. The disease occurs in two forms: primary as a result of atherosclerotic aortic aneurysm, aortitis, trauma, radiation, tumor invasion or penetrating ulcer, and secondary as a consequence of surgical aortal reconstruction. The clinical manifestation is mostly gastrointestinal bleeding, rarely back pain, fever and sepsis. Computed tomography with contrast medium is the most suitable diagnostic test, however, the diagnosis frequently requires explorative laparotomy. A case is presented of secondary arterio-enteric fistula, found two years after surgical treatment of chronic pancreatitis with pseudocystojejunostomy, which clinically manifested with gastrointestinal bleeding. Although there was strong suspicion of arterio-enteric fistula, the diagnosis was not verified by routine workup, but only on explorative laparotomy.

Abstract
We report a case of somatic type malignancy with papillary renal cell carcinoma differentiation arising in a retroperitoneal mixed germ cell tumor. The patient was a 36-year-old man with a synchronous mediastinal teratoma. The somatic type malignancy in the retroperitoneal tumor was composed of papillary structures covered by atypical epithelial cells with eosinophilic cytoplasm, prominent nucleoli and pseudostratified nuclei. Papillary cores contained numerous aggregates of foamy macrophages, typical of type I papillary renal cell carcinomas. The immunohistochemical profile was consistent with papillary renal cell carcinoma, including positive reactions for cytokeratin 7 and alpha-methyl acyl CoA racemase. There was no somatic type malignancy component in the synchronous mediastinal teratoma. Both the retroperitoneal and the mediastinal tumor showed gains of 12p and chromosome 17 material. There was no c-MET mutation in the somatic type malignancy. To our knowledge, this is the first report of a somatic type malignancy with features of papillary renal cell carcinoma arising in a germ cell tumor. It is important not to confuse such a retroperitoneal tumor with a conventional papillary renal cell carcinoma, because presence of other malignant histologies within the germ cell tumor may warrant different treatment. In such cases, the presence of isochromosome 12p can be helpful to the diagnosis.

Abstract
The last two decades have seen a paradigm shift in the treatment of vascular related diseases from once traditional open surgical repairs to the entire vascular tree being amenable to percutaneous interventions. Neither the classic operating room nor the conventional angiography suite is optimal for both open surgery and endovascular procedures. Important issues for the vascular hybrid operating room include quality of the imaging equipment, radiation burden, ease of use of the equipment, need for specially trained personnel, ergonomics, ability to perform both open and percutaneous procedures, sterile environments, as well as quality and efficiency of patient care. The most important feature of working in a dedicated hybrid vascular suite should be the ability to attain best treatment of vascular patients. Whether the interventional radiologist or the vascular surgeon uses the facilities is of less importance. Establishment of an endovascular operating room suite has the benefit of a sterile environment, and the possibility of performing hybrid procedures and conversions when necessary. Moreover, angiography immediately before treatment gives contemporary anatomical information, and after treatment provides quality control. Consequently, better quality and service can be provided to the individual patient. These changes in the treatment of vascular disease require that a new type of vascular specialist, named 'vascular hybrid surgeon', trained to perform both endovascular and open surgical procedures in this highly complex patient group.

Abstract
We report a case of spleen abscess cased by foreign body (gossypiboma) after 40 years. After physical examination, laboratory, ultrasonography and CT findings with diagnosis of acute abdomen, 73 years old woman had undergone laparatomy. Operation revealed intraabdominal spleen abscess. Capsulotomy and drainage of the collection was performed before splenectomy. Histological examination showed foreign body material surrounded by chronic inflammation, foreign body-type multinucleated giant cells, extravasated red blood cells and fibroblastic proliferation. From anamnesis we found that woman was operated only once during a life with diagnosis of extrauterine pregnancy, 40 years ago. Spleen abscess caused by gossypiboma after 40 years was never described before. However, diagnosis like this is very well known but rarely published because medical-legal implication. Education, professionalism and cooperation of all persons involved in surgical procedure are very important to prevent accidentally mistakes.

Abstract
INTRODUCTION A 64-year-old woman with a 2-year history of bilateral breast carcinoma with axillary node metastasis and chemotherapy was admitted to our hospital due to tumor attached to the ileum, discovered during the routine control examination. DISCUSSION Computerized axial tomography showed oval cystic tumor in terminal ileum that measured 7 cm in the largest diameter and shared peritoneal coat with small intestine and was filled with dense fluid. Tumor abutted intestine but did not communicate with intestinal lumen. The surgical procedure was simple because cyst was attached to the antimesenteric side of the terminal ileum and did not communicate with the adjacent intestine. Pathohistological examination showed mucinous cystadenoma with high-grade epithelial dysplasia in the isolated ileal duplication cyst. The presence of epithelial dysplasia found in duplication cyst suggested potential to undergo malignant transformation. CONCLUSION In conclusion, we report a unique case of mucinous cystadenoma arising in isolated ileal duplication cyst. This case report expands the potential range of clinical variability of alimentary tract duplications. Surgical removal of alimentary tract duplication in patients without symptoms is also recommended because many potential complications or even malignant transformation may result from these anomalies.

Abstract
We report a case of a 52-year-old man admitted to our hospital because of acute biliary pancreatitis caused by cholelithiasis. The patient also had choledocholithiasis complicated with pancreatic pseudocyst. Endoscopic retrograde cholangiopancreatography (ERCP) was performed and a large number of common bile duct stones were extracted with Dormia basket upon papillotomy. Pancreatic pseudocyst as a major complication of acute pancreatitis was also managed endoscopically by transpapillary stenting. Laparoscopic cholecystectomy with choledochotomy and choledochoscopy was performed for the final removal of biliary stones. Postoperative subhepatic abscess was resolved by ultrasound-guided percutaneous drainage. In this case biliary pancreatitis with all its complications was treated through minimally invasive endoscopic, percutaneous and surgical procedures. Minimally invasive techniques are much better because they reduce surgical stress, caused by reduction of flow through the splanchnic, which can also be reinforced by general endotracheal anesthesia. In the case when relative hypoxia occurs and acute serous pancreatitis transfers to acute necrotic pancreatitis, minimally invasive technique is the first and the best choice for surgical procedure.

Abstract
Between January 1st 1990 and December 31st 1999, 24 patients affected by Klatskin tumor underwent operation in our department of surgery. According to Bismuth's classification, there were 0 (0%) type I, 5 (21%) type II, 6 (25%) type IIIa, 4 (17%) type IIIb and 9 (37%) type IV tumors. Five patients (21%) were treated by curative resection (group I) while in 14 patients (58%) palliative surgical procedure was performed (group II). In 5 cases (21%) the extension of malignancy did not allowed any procedure (group III). Curative resection for malignant tumors of the hepatic duct bifurcation included wide tumor excision and bile duct resection at the liver hilum (with wedge hepatic resection in one patient) and creation of biliary-enteric anastomosis. Palliative surgical procedure included stent insertion. Jaundice was completely relieved in all patients undergoing resection, since 3 patients (21%) after stenting hadn't satisfactory biliary drainage. There was 1 (20%) perioperative death in the group 1, while in group 2, 5 patients (36%) died postoperatively. In this series, the mean postoperative survival of all patients was 16 months. The mean postoperative survival of patients undergoing localized tumor resection with curative intent was 38 months, in contrast to 10 months for those undergoing operative stent insertion. in addition, only 1 patient from group III, in whom only exploratory surgery were performed survived 7 months, while other 4 patients died in the hospital. This retrospective review suggests that aggressive surgical treatment could improve survival and quality of life in patients suffering from Klatskin tumor.

Abstract
BACKGROUND/AIMS Thermal trauma is hypothesized as a major cause of late common bile duct stricture. Dispersion of electric energy through the tissues during electrocautery is not controlled and may cause necrosis even in remote tissues. Changes in liver enzymes may be used as indirect indicators of common bile duct damage, because of the close proximity of these structures in the liver porta. METHODOLOGY Laparoscopic cholecystectomy was performed in 20 patients using a monopolar cutter (thermal device), and in another 20 patients using a harmonic scalpel (non-thermal device). Changes in liver enzymes, as well as histology of gallbladder wall were assessed. RESULTS There was a significant rise in liver enzymes (AST and ALT) after surgery in both groups, but postoperative values of these two enzymes were significantly higher in patients operated using the monopolar cutter. There were no significant differences in postoperative levels of hemoglobin and red blood cell count between these two groups. CONCLUSIONS Thermal trauma of the liver parenchyma was significantly greater in patients operated using the monopolar cutter, suggesting possible detrimental effects to the common bile duct.

Abstract
Gallstone ileus is an uncommon cause of small bowel obstruction, accounting for only 1% to 4% of all intestinal obstructions. In the group of patients over 65 years of age, gallstones cause about 25% of all non-strangulated obstructions of the small bowel. Gallstone ileus is burdened with high mortality rate, ranging from 12% to 18%, and most patients are of advanced age, with many other concomitant diseases that may increase the operative risk. The purpose of this study was to compare the two investigated surgical procedures: treatment of intestinal obstruction alone or combined with urgent cholecystectomy and fistula repair. Analysis of 30 patients undergoing operation for gallstone ileus at the Clinical Hospital "Sestre milosrdnice" between 1985 and 2001 is presented. Patients were treated either for ileus alone (group 1, 11 patients) or as one-stage procedure with urgent fistula closure (group 2, 19 patients). Operating time was significantly longer for the one-stage procedure. Complications occurred in 3 of 11 patients (27.3%) from group 1 and in 11 of 18 patients (61.1%) from group 2 (one tailed, p = 0.043). One patient in group 1 died and two patients in group 2 died. Urgent fistula repair was significantly associated with the occurrence of complications (odds ratio [OR] 12.1, 95% confidence internal [95% CI] 1.2-121.5). Simple enterotomy should be the procedure of choice for patients with gallstone ileus. The one-stage procedure including urgent fistula repair should be reserved only for highly selected patients with absolute indications.

Abstract
Multiple primary cancers occurring in the same patients have been reported to represent 1.8-3.9% of all cancers. The majority of all patients reported to have had a combination of simultaneous neoplastic changes in the ampulla of Vater and the colon showed familial adenomatous polyposis (FAP) syndrome. Variants of familial adenomatous polyposis coli are: attenuated adenomatous polyposis coli (AAPC, previously also known as flat adenoma syndrome) and multiple adenoma coli. AAPC is characterized clinically by many, but usually fewer than 100, colonic lesions that are characteristically slightly elevated and plaque-like, with a reddish surface and sometimes central depression. Genetically it represents an extremely rare variant of FAP. Another group of individuals, so-called multiple adenoma patients, have a phenotype similar to AAPC, but most have no demonstrable germ-line adenomatous polyposis coli mutation, as do patients with FAP or AAPC. However, there have been only a few reports that discussed concurrent neoplastic changes in the ampulla of Vater and colon in patients with multiple colonic flat adenomas, but without the florid phenotype of classical FAP. We present rare clinical course of a patient with multiple (more than 60) flat adenomas in the proximal colon and two primary cancers: of the ampulla of Vater and of the ascending colon. This patient and his family history did not show polyposis compatible with FAP or hereditary nonpolyposis colorectal cancer (HNPCC) syndrome.

Abstract
Histopathologic and clinical data strongly suggest a causal relation between Helicobacter pylori infection and gastritis, peptic ulcer disease, or both. However, little has been written about the potential association between H. pylori infection and Brunner's gland adenoma. Therefore, we carried out a prospective study to determine the presence of H. pylori infection among patients with Brunner's gland adenoma. From November 1996 till October 1999, 19100 patients who had undergone upper gastrointestinal endoscopy at two clinical centers in Zagreb, Croatia, were candidates for participation in the study. Brunner's gland adenoma was diagnosed on the basis of histologic samples taken from the polyp (four patients) or after the entire polyp was made available upon endoscopic removal (three patients). When all endoscopic examinations had been performed, biopsy samples were taken from the antrum and body of the stomach, so that gastritis could be classified and H. pylori determined by histology. Biopsy samples were also taken from the duodenal bulb to verify duodenitis. Two other samples were taken from the antrum for rapid urease test. The patients were considered positive for H. pylori when both histology and rapid urease test were positive. Brunner's gland adenoma was diagnosed in seven patients (five women and two men; median age, 49 yrs). Five (71%) patients with diagnosed Brunner's gland adenoma had concurrent H. pylori infection. Duodenitis associated with gastric metaplasia was observed in six patients. Complete eradication of H. pylori was achieved in only two patients. Symptoms disappeared or markedly diminished in all patients with significant improvement during therapy or immediately upon endoscopic removal of the polyp. Although limited by a very small number of patients, our results suggest that concurrent H. pylori infection is very common in patients with Brunner's gland adenoma. However, the role of H. pylori infection in the pathogenesis and development of Brunner's gland hyperplasia remains unclear.

Abstract
Prospective investigation has been undertaken with the aim to study the frequency, location and age and sex distribution of various histological types of benign gastric epithelial polyps. Histological type--adenomatous, hyperplastic and fundic gland polyps--was diagnosed on the basis of at least three histological samples taken from the polyp. Biopsy samples were also taken from the antrum and the body of the stomach so that gastritis could be graded and classified, and the presence of H. pylori could be determined by histology. All 6,700 patients, who had undergone upper gastrointestinal endoscopy in a one-year period, participated in this study. Among them 42 benign gastric epithelial polyp were found in 31 patients: adenomatous gastric polyps in 7 patients, hyperplastic gastric polyp in 21 and fundic gland polyp in 3 patients. All patients with hyperplastic polyps had chronic active superficial gastritis, whereas most of the patients with adenomatous polyps had a chronic atrophic gastritis with high prevalence of intestinal metaplasia. Among 21 patients with hyperplastic gastric polyps, 16 (76%) patients were positive for H. pylori infection in contrast to only 2 patients (29%) with adenomatous gastric polyps and 1 patient (33%) with fundic gland polyp. Presented data indicates that hyperplastic gastric polyps are the most common and they are associated with the presence of chronic active superficial gastritis and concomitant H. pylori infection. Adenomatous polyps are rarer and they tend to be associated with chronic atrophic gastritis and intestinal metaplasia. Fundic gland polyp is the rarest type of gastric polyps.

Abstract
The occurrence of inflammatory bowel disease in patients with glycogen storage disease lb is rare (GSD-lb). We present the case of a young woman with the diagnosis of GSD-lb Crohn-like colitis developed at age 22. Clinical evaluation revealed severe malnutrition, secondary amenorrhea, leukopenia, neutropenia, dysfunctions of phagocytosis, and subtotal stenosis of the ascending colon. Right hemicolectomy was performed and pathohistologic analysis of the resected bowel showed chronic bowel inflammation consistent with Crohn disease. Clinical status of the patient markedly improved after surgery.

Abstract
Liver resection is the only potentially curative method for patients with colorectal cancer metastases and 5-year survival rates are 20%-40%. Simultaneous resection of colorectal cancer and synchronous liver metastases has been recommended if minor hepatectomy is indicated. The purpose of this paper is to analyze the treatment of hepatic colorectal secondaries and to assess the safety of simultaneous and delayed liver resections and relations of morbidity to the extensiveness of hepatectomy and perioperative factors. Analyzed were 21 patients with liver metastases from colorectal cancer operated between 1997 and 1999 in the Clinical Hospital "Sestre milosrdnice". Operating time for simultaneous colorectal and liver resections was not significantly longer compared to liver resections alone. No significant difference in complication rate was found after simultaneous procedures and liver resection alone (38% vs. 31%). Complication rate after major liver resections was not significantly greater than after minor resections (38% vs. 31%). No statistically significant differences were found in operation time and blood replacement between patients who developed postoperative complications and those who did not. In conclusion, simultaneous resections of primary colorectal cancer and liver metastases may be considered safe. Morbidity rates are not significantly different from those after liver resections alone, nor depend significantly upon the extensiveness of liver resection, providing that the operation time and blood loss are within the range observed in this study.

Abstract
BACKGROUND/AIMS Spontaneous bacterial peritonitis is one of the most common complications attending the onset of ascites in patients with liver cirrhosis. The aim of this study was to demonstrate whether it is possible, on the basis of ascitic fluid polymorphonuclear cell count in patients with liver cirrhosis and spontaneous bacterial peritonitis, to determine the optimal duration of cefotaxime therapy, as the most frequently applied empirical therapy, and possibly anticipate the disease recurrence. METHODOLOGY In 16 patients with alcoholic liver cirrhosis and confirmed diagnosis of spontaneous bacterial peritonitis, cefotaxime therapy was administered 2g t.i.d. during 5 days. Before the therapy, at 48 hours, 5 days and 15-20 days after the cefotaxime therapy was started, in all patients with spontaneous bacterial peritonitis diagnostic abdominal paracentesis was performed, each time determining the ascitic fluid polymorphonuclear cell count together with microbiological analysis. RESULTS In the course of the "primary" spontaneous bacterial peritonitis attack, 3 patients died (18.8%). In 4 patients the recurrence of spontaneous bacterial peritonitis was observed within 15-20 days after therapy was discontinued. Two patients died during the therapy of spontaneous bacterial peritonitis recurrence. After 48 hours of therapy, 11 patients with the "primary" spontaneous bacterial peritonitis attack were without any symptoms (68.8%). Out of these 11, 10 patients (62.5%) had the ascitic fluid polymorphonuclear cell count lower than 250/mm3. After 5 days of therapy, 12 patients (75%) were free of symptoms, and the number of ascitic fluid polymorphonuclear cell count < 250/mm3 was still found in 10 (62.5%) patients. No association between the presence of symptoms 48 hours after the therapy and the recurrence of spontaneous bacterial peritonitis was established. A significant association was found between the ascitic fluid polymorphonuclear cell count determined 48 hours after the therapy and the recurrence of spontaneous bacterial peritonitis. A recurrence occurred in only 1 patient with the number of ascitic fluid polymorphonuclear cell count < 250/mm3, 48 hours after the therapy was started. A recurrence of spontaneous bacterial peritonitis occurred in all the patients who had an ascitic fluid PMN cell count > or = 250/mm3, 48 hours after the therapy was started. CONCLUSIONS By monitoring the ascitic fluid PMN cell count it seems to be possible to determine the efficacy and optimal duration of cefotaxime therapy in patients with spontaneous bacterial peritonitis when it is of most importance that the number of ascitic fluid PMN cell count should decrease below 250/mm3 during the therapy.

Abstract
OBJECTIVE Histopathological and clinical data strongly suggest that Helicobacter pylori is the cause of chronic gastritis and peptic ulceration. However, little has been written about the potential causal relation of H. pylori infection to hyperplastic and adenomatous gastric polyps. We therefore carried out a prospective study to determine the effect of eradicating H. pylori infection on the course of hyperplastic and adenomatous gastric polyps. METHODS From November 1996 to December 1997, 6700 patients who had undergone upper gastrointestinal endoscopy at the two centres in Zagreb, Croatia, were candidates for participation in the study. Hyperplastic and adenomatous polyps were diagnosed on a basis of at least three histological samples taken from the polyp. In seven patients endoscopy had to be repeated because forceps biopsy sampling either provided inadequate tissue for correct histological diagnosis, or accurate characterization of gastric polyp histology was not possible. Upon completion of all endoscopic examinations before and after treatment, biopsy samples were taken from the antrum (two) and the body of the stomach (two) so that gastritis could be graded and classified, and the presence of H. pylori sought by histology. Two other samples were taken from the antrum for a rapid urease test. Follow-up examinations were performed by using endoscopy. Control endoscopy was performed at least 4 weeks after the treatment of H. pylori infection had been completed, and then every 3-4 months. The follow-up ranged from 4 to 17 months, with a median of 14 months. The treatment of H. pylori infection consisted of a 1-week course of either omeprazole (20 mg twice daily) or pantoprazole 40 mg twice daily), and a 1-week course of amoxicillin 2g twice daily) and metronidazole (400 mg three times daily), and clarithromycin (500 mg twice daily). Eradication of H. pylori infection was assessed by repeated histology and rapid urease test. RESULTS Twenty-one patients (nine women, 12 men; median age 52 years) with histologically proven hyperplastic gastric polyps, and seven patients (two women, five men; median age, 67 years) with adenomatous gastric polyps were included in the study. Among 21 patients with hyperplastic gastric polyps, 16 patients (76%) were positive for H. pylori infection. Only two patients (29%) with adenomatous gastric polyps were positive for the infection. Complete eradication of H. pylori was initially achieved in all patients positive for H. pylori. Total regression of the gastric polyps was observed only among the patients with hyperplastic gastric polyps in whom H. pylori had been eradicated. Complete regression of the hyperplastic gastric polyps was observed in seven of the 16 evaluable patients (44%; 95% CI, 19-68%) after H. pylori eradication. The endoscopic snare polypectomy was carried out in nine patients with hyperplastic polyps and two patients with adenomatous gastric polyps in whom regression of the polyps was not observed after H. pylori eradication, as well as in five patients with hyperplastic and four with adenomatous gastric polyps who were negative for H. pylori. Exploratory laparotomy and gastrotomy with polyps excision were carried out in one patient with multiple adenomatous gastric polyps. In only one patient who was not positive for H. pylori recurrence of hyperplastic gastric polyp was recorded during follow-up, and no re-infection with H. pylori has been detected. CONCLUSIONS Our results suggest that the development of hyperplastic gastric polyps may be directly related to chronic active gastritis and concomitant H. pylori infection. Cure of H. pylori infection associated with hyperplastic gastric polyps resulted in complete polyp regression in more than 40% of patients. Therefore, for patients with hyperplastic gastric polyps and concurrent H. pylori infection an antibiotic treatment designed to eradicate H. pylori appears to be recommended before further therapeutic options are consi

Abstract
Medical therapy for reflux esophagitis is designed to provide symptom relief and esophageal healing, and to prevent complications. Life-style modifications serve as an adjunct to drug therapy. Histamine-H2-receptor antagonists and prokinetic agents promote symptom relief and esophageal healing in mild esophagitis, but are less effective in the treatment of moderate to severe esophagitis. For patients with moderate to severe esophagitis, rapid symptom relief and esophageal healing have been achieved with proton pump inhibitors. These patients usually require maintenance therapy with proton pump inhibitors.

Abstract
The purpose of this article is to take firm position on the surgical treatment of the carotid artery aneurysm on the basis of ten years of experience, considering their rare occurrence and significant pathology. From January 1984 to December 1994, ten patients with aneurysms or pseudoaneurysms of extracranial carotid arteries were diagnosed and operated in the Department of Vascular Surgery, Clinical Hospital "Sestre milosrdnice" in Zagreb. In the same period, eight hundred operations of extracranial carotid arteries were performed. Special emphasis is put on the etiology of the disease where atherosclerosis is prevalent, but cases of traumatic, mycotic and postoperative aneurysms are also shown. In symptomatology, signs of palpable local tumor dominated in six patients, while in three patients central nervous system symptoms were found. All patients with neurologic symptoms were in the group with atherosclerotic aneurysms. In nine patients resection of the aneurysm and reconstruction with the interposition of a part of vena saphena magna or with allograft was performed. In one patient, neoanastomosis of the internal carotid artery in the common carotid artery was performed following the resection of a small aneurysm. In the early postoperative period there was no morbidity nor mortality. In view of frequent preoperative neurologic complications and good postoperative results, surgical treatment is indicated in all cases. Reconstruction is always indicated, and the procedure of choice is reconstruction with the interposition of a part of great saphenous vein.
