The RdRp genotyping of SARS-CoV-2 isolated from patients with different clinical spectrum of COVID-19.

BACKGROUND: The evolution of SARS-CoV-2 has been observed from the very beginning of the fight against COVID-19, some mutations are indicators of potentially dangerous variants of the virus. However, there is no clear association between the genetic variants of SARS-CoV-2 and the severity of COVID-19. We aimed to analyze the genetic variability of RdRp in correlation with different courses of COVID-19. RESULTS: The prospective study included 77 samples of SARS-CoV-2 isolated from outpatients (1st degree of severity) and hospitalized patients (2nd, 3rd and 4th degree of severity). The retrospective analyses included 15,898,266 cases of SARS-CoV-2 genome sequences deposited in the GISAID repository. Single-nucleotide variants were identified based on the four sequenced amplified fragments of SARS-CoV-2. The analysis of the results was performed using appropriate statistical methods, with p < 0.05, considered statistically significant. Additionally, logistic regression analysis was performed to predict the strongest determinants of the observed relationships. The number of mutations was positively correlated with the severity of the COVID-19, and older male patients. We detected four mutations that significantly increased the risk of hospitalization of COVID-19 patients (14676C > T, 14697C > T, 15096 T > C, and 15279C > T), while the 15240C > T mutation was common among strains isolated from outpatients. The selected mutations were searched worldwide in the GISAID database, their presence was correlated with the severity of COVID-19. CONCLUSION: Identified mutations have the potential to be used to assess the increased risk of hospitalization in COVID-19 positive patients. Experimental studies and extensive epidemiological data are needed to investigate the association between individual mutations and the severity of COVID-19.

Comparative study of virulence potential, phylogenetic origin, CRISPR-Cas regions and drug resistance of Escherichia coli isolates from urine and other clinical materials.

Introduction: Urinary tract infections (UTI), among which the main etiological factor is uropathogenic Escherichia coli (UPEC, E. coli), remain an important issue for clinicians. The aim of the study was to demonstrate clear differences in the pathogenic properties of urine-derived E. coli compared to other extraintestinal E. coli clinical isolates (derived from: blood, lower respiratory tracts, sputum, reproductive tract, body fluids, perianal pus, other pus, wound, postoperative wound and other sources). Methods: The collection of 784 E. coli isolates was collected from various materials of hospitalized patients. They were analyzed in terms of virulence-associated genes (papC, sfaD/sfaE, cnf1, usp., fimG/H, hlyA), belonging to phylogenetic groups and the presence of CRISPR-Cas regions using PCR. In addition, the epidemiological data and the antibiotic resistance profiles provided by the hospital's microbiology department were included for statistical analyses. Results: Urine-derived E. coli showed significantly greater virulence potential compared to other isolates, but they were generally unremarkable in terms of drug resistance. The isolates most often belonged to phylogenetic group B2. Drug resistance was negatively correlated with CRISPR 2 presence and high average virulence score, but positively correlated with CRISPR 4 presence. To the best of our knowledge, we are the first to report significant differences in sputum-derived isolates-they revealed the lowest virulence potential and, at the same time, the highest drug resistance. Discussion: In conclusion, we demonstrated significant differences of urinary-derived E. coli compared to other clinical E. coli isolates. We would like to suggest excluding penicillins from use in E. coli infection at this time and monitoring strains with a high pathogenicity potential.

Closing A Temporary Stoma - The Procedure Tactics.

The paper presents the results of clinical trials and meta-analyses regarding the closing time of: ileostomy (protective) after primary colorectal resection with anastomosis and colostomy - after Hartman's surgery. Rectal cancer surgery and ileal pouch-anal anastomosis (IPAA) in inflammatory bowel diseases often involves an ileostomy (temporary protective, preventive), which in a significant proportion of cases is eliminated at different times from the initial surgery. There is a discussion in the literature regarding the selection of the appropriate time of stoma closure, taking into account the experience of many clinical centers. An ileostomy is performed when the entire colon and rectum must be removed, or to protect the colon or ileorectal anastomosis. The creation of a protective stoma reduces the frequency of clinically significant anastomotic leakages and the need for surgical revisions in patients at increased risk of leakage. Also, the time of digestive system reconstruction, i.e., colostomy elimination, after Hartman's surgery depends on many factors, including the stage of disease and indications for adjuvant treatment. Should it be standard practice to close the stoma early? Based on previous studies and meta-analyses, as well as own experience - it is advisable to individualize the procedure, taking into account many factors that determine the clinical and oncological status (selection of the date - early or deferred, but not as a standard [!]).

Splanchnic Vein Thrombosis in Acute Pancreatitis and Its Consequences.

Splanchnic vein thrombosis (SVT) is a serious vascular complication that can occur in patients with acute pancreatitis. We assessed the incidence of SVT and its relationship with acute pancreatitis (AP) and associated complications. We carried out a retrospective analysis of medical histories from patients hospitalized with AP in a single surgical center. Histories were acquired from patients with abdominal and pelvic computed tomography scans performed between the 2nd and 3rd day of hospitalization. We assessed the impact and extent of thrombosis over the disease course. We found a strong positive correlation (Cramer's V coefficient = 0.34) between SVT and disease severity. Mortality in the study group was 7.2% (8 patients) of which 5 patients (62.5%) were diagnosed with SVT. We observed an increased incidence of death among patients with thrombosis, with results approaching significance (P = 0.056). In our study, we found that SVT has a negative effect on the course of AP and is associated with more severe disease and increased mortality.

The Effect of Bariatric Surgery on Weight Loss and Metabolic Changes in Adults with Obesity.

Methods of treating obesity, such as changes in lifestyle, physical activity, restrictive diets, and psychotherapy, are not sufficient. Currently, it is considered that in the case of patients who meet the eligibility criteria for surgery, the treatment of choice should be bariatric surgery. The aim of this study was to assess the weight loss and metabolic changes in a group of adults with obesity undergoing bariatric surgery. The study involved 163 patients whose body mass index (BMI) exceeded 40 or 35 kg/m2, concurrent with at least one metabolic sequelae. In 120 of the cases (74%), sleeve gastrectomy was used; in 35 (21%), gastric bypass was used; and in 8 (5%), laparoscopic Roux-en-Y bypass was used. Metabolic parameters such as total cholesterol, LDL-cholesterol (low-density lipoprotein cholesterol), HDL-cholesterol (high-density lipoprotein cholesterol), triglycerides, and glucose were measured preoperatively and postoperatively, as well as the creatinine, creatine kinase (CK-MB), and leptin activity. In patients undergoing bariatric surgery, a significant decrease in excess weight (p < 0.001) was observed at all the analyzed time points, compared to the pre-surgery value. Weight loss after surgery was associated with a significant improvement in glycemia (109.6 ± 48.0 vs. 86.6 ± 7.9 mg/dL >24 months after surgery; p = 0.003), triglycerides (156.9 ± 79.6 vs. 112.7 ± 44.3 mg/dL >24 months after surgery; p = 0.043) and leptin (197.50 ± 257.3 vs. 75.98 ± 117.7 pg/mL 12 months after surgery; p = 0.0116) concentration. The results of the research confirm the thesis on the effectiveness of bariatric surgery in reducing excess body weight and improving metabolic parameters in patients with extreme obesity.

Fournier gangrene - a challenge for the surgeon.

INTRODUCTION: Fournier gangrene (FG) is life - threatening condition, defined as the necrotizing fascitis of perineum and can spread to the adjacent areas. It is rare disease and infection is caused by mixed bacterial flora, seldom by fungal infection. Risk factors are: male sex, diabetes, hypertension, malignant neoplasms, alcoholism, immunospression. MATERIAL AND METHODS: The analysis of four group patients treateted for Fournier gangrene was made about diagnostic and therapeutic process, assessment of prognosis based on Fournier's Gangrene Severity Index). RESULTS: All patients were males. Average age at the moment of diagnosis was 60 years. All of them had comorbidities resulting with the higher risk of susceptibility to FG. Morbitity was 50%, despite of all of patients had less than 9 points in FGSI. DISCUSSION: The FG, despite of better diagnostic tools and technological progres remaines the significant clinical issue because of the mortality - 80%. "The golden standard" is surgical excision of necrotic tissues, antibiotics support, equation of fluid, electrolytes and base - acid balance, level of glycemia is very important. The treating results were assessed on the base of FGSI. The significance has the moment of performing the surgical intervention - it is proven, that should be carried out during 24 hours. The hyperbaric oxygen therapy is controversial. Seem to be appropriate if the infection is caused by anaerobic bacteria. CONCLUSIONS: Fournier syndrome is significant clinical issue. Its treatment requires early surgical approach with exicision of necrotic tissues, antibiotics support and treatment of hyperbaric oxygen in some cases.

Tumor Digital Masking Allows Precise Patient Triaging: A Study Based on Ki-67 Scoring in Gastrointestinal Stromal Tumors.

BACKGROUND: Technological advances constantly provide cutting-edge tools that enhance the progress of diagnostic capabilities. Gastrointestinal stromal tumors belong to a family of mesenchymal tumors where patient triaging is still based on traditional criteria such as mitotic count, tumor size, and tumor location. Limitations of the human eye and randomness in choice of area for mitotic figure counting compel us to seek more objective solutions such as digital image analysis. Presently, the labelling of proliferative activity is becoming a routine task amidst many cancers. The purpose of the present study was to compare the traditional method of prediction based on mitotic ratio with digital image analysis of cell cycle-dependent proteins. METHODS: Fifty-seven eligible cases were enrolled. Furthermore, a digital analysis of previously performed whole tissue section immunohistochemical assays was executed. Digital labelling covered both hotspots and not-hotspots equally. RESULTS: We noted a significant diversity of proliferative activities, and consequently, the results pointed to 6.5% of Ki-67, counted in hotspots, as the optimal cut-off for low-high-grade GIST. ROC analysis (AUC = 0.913; 95% CI: 0.828-0.997, p < 0.00001) and odds ratio (OR = 40.0, 95% CI: 6.7-237.3, p < 0.0001) pointed to Ki-67 16% as the cut-off for very high-grade (groups 5-6) cases. With help of a tumor digital map, we revealed possible errors resulting from a wrong choice of field for analysis. We confirmed that Ki-67 scores are in line with the level of intracellular metabolism that could be used as the additional biomarker. CONCLUSIONS: Tumor digital masking is very promising solution for repeatable and objective labelling. Software adjustments of nuclear shape, outlines, size, etc. are helpful to omit other Ki-67-positive cells especially small lymphocytes. Our results pointed to Ki-67 as a good biomarker in GIST, but concurrently, we noted significant differences in used digital approaches which could lead to unequivocal results.

CTRC gene polymorphism may increase pancreatic cancer risk - preliminary study.

Pancreatic cancer is often fatal due to delayed diagnosis and treatment difficulties. OBJECTIVE: To analyze selected SPINK1, CTRC, CFTR, and PRSS1 gene mutations in cancer tissue and blood samples of patients with pancreatic tumors. MATERIALS AND METHOD: We enrolled 16 consecutive patients diagnosed with pancreatic tumors. We collected cancer tissue, normal pancreatic tissue, and blood samples for genetic tests. The control group consisted of 419 healthy individuals. Peripheral blood samples were collected from all study participants in EDTA-coated tubes. RESULTS: Out of 16 patients with pancreatic tumors, 12 had pancreatic cancer on microscopic examination (mean age, 60.2 years). The CTRC polymorphism Hetero p.G60=(c.180C>T) was found in 5 patients with pancreatic cancer (41.7% vs. 18.6% in the control group). One patient with pancreatic cancer and a positive family history had the SPINK1 (p.N34S) mutation [8.3% vs. 2.9% (12/419) in the control group]. One patient with pancreatic cancer had the CTRC (p.R254W) mutation [8.3% vs. 1% (4/419) in the control group]. CONCLUSIONS: Our preliminary results show that the CTRC polymorphism p.G60= (c.180C>T) is frequent in patients with pancreatic cancer. However, further research is needed to verify our findings.

CD63 and GLUT-1 Overexpression Could Predict a Poor Clinical Outcome in GIST: A Study of 54 Cases with Follow-Up.

Background and Goals. In light of current knowledge, it seems that alternations underlying GISTs are well explained, although all that is enhanced by various aspects on a daily basis. More recently, attention has been pointed towards exosomes as important particles able to modify healthy and also diseased tissues including cancer. The goal of the present study was an analysis of CD9, CD63, and GLUT-1 as a marker of hypoxia status within 54 cases of GIST and evaluation of their predictive value. Methods. 54 cases of patients suffering from GIST were enrolled into the study, predominantly in the gastric location. All operated cases had no Imatinib and other chemotherapies up to the day of operation. Expression of targeted proteins was performed by immunohistochemistry and, after that, the results with tabulated clinical data were compared by Kaplan-Meier method and multivariate Cox proportional hazard model of statistical analysis. Results. Our results presented a marked dependence of worsening clinical outcome with high expression CD63 (p = 0.008) as well as with GLUT-1 (p = 0.014). We noted a strict correlation of GLUT-1 expression with CD63 expression (p = 0.03), which could confirm the thesis about the contribution of exosomes in intratumoural hypoxia status. The collected material did not confirm CD9 contribution. Conclusions. As presented here, CD63 and GLUT-1 have a prognostic value in GIST cases. The results confirm the other studies in this scope and can be used in future as an additional prognostic factor.

Reoperations in bariatric surgery - indications and initial evaluation of postoperative complications.

UNLABELLED: Obesity, at present, seems to be a very serious health problem all over the world. The surgery is said to be the most successful treatment of obesity. With the increase in the quantity of conducted bariatric procedures, the number of revision treatments increases as well. The aim of the study was to analyze the indications, results and complications after repeated bariatric surgeries. MATERIAL AND METHODS: The repeated bariatric procedures performed in 2009-2015 have been retrospectively analyzed. The endpoint of the study was the evaluation of early surgical treatment results-up to 30th day after repeated surgery. RESULTS: Overall, amongs 103 obese patients with a BMI over 35 kg / m2, qualified for bariatric treatment 7 revision surgeries were conducted (6.8%). Two operations were carried out by laporotomy, other by laparoscopy. In the study group, neither any deaths were noted in perioperative period nor life-threatening complications. The frequency of complications-Surgical site infection and bleeding from the staple lines of stapler in the study group appeared to be 28.6%. CONCLUSIONS: Qualification for repeated bariatric surgeries should be based on a thorough analysis of the condition of the patient, previous outcome of the bariatric treatment: evaluation of weight loss as well as possible complications of the original surgery.

Gastric gastrointestinal stromal tumor with incomplete duplication cyst - a case with possibility of neoplasia in fetal-period malformed tissues.

The coincidence of GIST and other gastric malignancies are documented well but arising GIST from congenital anomalies is still rarity in literature. To date, only a few papers have been concerned on the possibility of arising neoplasms from duplication cyst of gastrointestinal tract. There, are dominating usual cancers, neuroendocrine cancers or lymphomas but GIST has been noted only once. Here, we report a case of 73 years old female-patient with typical gastric stromal tumor comprised centrally locked an incomplete duplication cyst.

Comparative analysis of selected scales to assess prognosis in acute pancreatitis.

OBJECTIVE: To evaluate the utility of selected scales to prognosticate the severity and risk for death among patients with acute pancreatitis (AP) according to the revised Atlanta classification published in 2012. METHODS: Prospective data regarding patients hospitalized due to AP were analyzed. The final analysis included a total of 1014 patients. The bedside index for severity in acute pancreatitis (BISAP), Panc 3 scores and Ranson scales were calculated using data from the first 24 h of admission. RESULTS: Mild AP was diagnosed in 822 (81.1%) cases, moderate in 122 (12%) and severe in 70 (6.9%); 38 (3.7%) patients died. The main causes of AP were cholelithiasis (34%) and alcohol abuse (26.7%). Recurrence of AP was observed in 244 (24.1%) patients. In prognosticating the severity of AP, the most useful scale proved to be the Acute Physiology and Chronic Health Evaluation (APACHE) II (area under the curve [AUC] 0.724 [95% CI 0.655 to 0.793]), followed by BISAP (AUC 0.693 [95% CI 0.622 to 0.763]). In prognosticating a moderate versus mild course of AP, the CT severity index proved to be the most decisive (AUC 0.819 [95% CI 0.767 to 0.871]). Regarding prognosis for death, APACHE II had the highest predictive value (AUC 0.726 [95% CI 0.621 to 0.83]); however, a similar sensitivity was observed using the BISAP scale (AUC 0.707 [95% CI 0.618 to 0.797]). CONCLUSIONS: Scoring systems used in prognosticating the course of the disease vary with regard to sensitivity and specificity. The CT severity index scoring system showed the highest precision in prognosticating moderately severe AP (as per the revised Atlanta criteria, 2012); however, in prognosticating a severe course of disease and mortality, APACHE II proved to have the greatest predictive value.

Severe Vascular Complications Of Acute Pancreatitis.

UNLABELLED: Acute pancreatitis (AP) develops as a result of the imbalance of the mechanisms inhibiting the activity of enzymes in the pancreatic cells, which causes their autoactivation in the pancreas. The incidence of AP ranges from 10 up to 100 cases per 100,000 population per year in different parts of the world. The overall mortality rate for acute pancreatitis is 10-15%. The mortality rate in patients diagnosed with the severe form of acute pancreatitis is up to 30-40%. MATERIAL AND METHODS: The study included 10 patients treated due to acute pancreatitis in two surgical departments run by one of the authors (S.G.) in the years 2004-2014, who developed a serious complication in the form of haemorrhage into the inflammatory tumour/pancreatic cyst or an adjacent organ. Haemorrhage was diagnosed based on the clinical picture, most often a sudden drop in blood pressure, peritonitis symptoms and imaging findings--abdominal ultrasound and abdominal computed tomography. Therapeutic methods included conservative treatment, endovascular embolisation and, in the absence of efficacy of the above mentioned methods, surgical treatment. Patients age and gender, the etiological factor, comorbidities, Atlanta Classification, treatment outcomes and mortality rate were assessed. RESULTS: Alcohol was the most common etiological factor in the investigated AP cases. The patients received conservative treatment, interventional radiology treatment (endovascular embolisation) or surgical treatment. In the study group, 6 patients required surgical treatment, 3 patients received invasive radiology treatment, and conservative treatment was used in one patient. The mortality rate in the study group was 30%. CONCLUSIONS: Haemorrhages into the inflammatory cisterns or adjacent organs (stomach, transverse colon mesentery) secondary to AP are the most severe complications, which are difficult to manage. The successful use of interventional radiology methods to inhibit and prevent the recurrence of bleeding in some of the patients is a significant milestone.

Risk Factors Of Pancreatitis After Endoscopic Retrograde Cholangiopancreatography--A Retrospective Cohort Study.

UNLABELLED: Endoscopic retrograde cholangiopancreatography (ERCP) is the most important non-surgical procedure in serious pancreatic and biliary diseases, still burdened with the risk of severe complications. The objective of the study was to distinguish factors which could increase the risk of occurrence of ERCP complication in the form of pancreatitis. MATERIAL AND METHODS: The study included 452 patients who had undergone ERCP. Patients' records were retrospectively analyzed from the aspect of demographic data, indications for the procedure, type and course of the procedure, type and severity of complications, width of the common bile duct (CBD), concomitant diseases and administered medicines which might increase the risk of complications. RESULTS: In 35 patients (7.7%) a complication occurred in the form of pancreatitis (AP). A severe course was confirmed in 11 patients (31%). Cholelithiasis constituted approximately 2/3 of indications for ERCP. AP after ERCP was significantly more often observed in the group of patients aged under 40 (22.9% vs 8.6%; p<0.05). Narrow biliary ducts (3-8 mm) were the factor increasing the frequency of development of AP (25.9% vs 45%; p<0.05). Death occurred in 5 patients (1.1%), including 4 patients (0.96%) in the group without complications, and in 1 patient (2.85%) with complicated AP. CONCLUSIONS: ERCP is a very valuable procedure in clinical treatment; however, it is burdened with the risk of complications, such as AP, bleeding, or duodenal perforation. A group especially exposed to the risk of complications in the form of AP are young patients aged under 40 with a narrow CBD.

Intramuscular high-grade myxofibrosarcoma of left buttock of 66-year-old male patient - approach to systematic histopathological reporting.

Here we present a systematic approach to histopathological reporting of high-grade myxofibrosarcoma of 66-year-old male patient. The tumor was biopsied with fine-needle aspiration (FNA) and core-needle biopsy (CNB) and then the whole myxoid tumor was excised with left musculus gluteus maximus. The lesion was stained with Hematoxylin-Eosin (HE), Periodic acid-Schiff (PAS), Alcian blue, Masson's trichrome, Ki67, alpha-smooth muscle actin (α-SMA), S100, CD34 and vimentin. FNA material grounded the diagnosis of non-epithelial neoplasia, while CNB was enough to produce diagnosis of myxoid sarcoma. The tumor lied under superficial fascia with no extension beyond deep fascia or any invasion of skin, vessels or nerves, either. The tumor was intramuscular, mainly myxoid with hypercellular areas of highly atypical cells with bizarre giant multinucleated cells that clearly belonged to category of high-grade sarcoma. According to Fédération Nationale des Centres de Lutte Contre le Cancer (FNCLCC), the case was assessed for 5 points. Ki67 index reached more than 80% malignant cells. Alcian blue was strongly positive in myxoid background. Masson's trichrome emphasized fibrillary structure of tumor. Negativity for S100, α-SMA with strong co-expression of CD34 and vimentin supported the diagnosis of myxofibrosarcoma. The lesion was diagnosed as high-grade myxo-fibrosarcoma (formerly myxoid malignant fibrous histiocytoma) G2 pT2b [7th edition pTNM (pathological tumor-node-metastasis), code ICD-O 8811/3 in World Health Organization (WHO) Classification 2013]. In approach to diagnosis of soft tissue malignancies, a strict sequence of procedures should be applied as only meticulous and ordered diagnostic pathway would succeed in and correct identification of a peculiar type of sarcoma.

The influence of splenectomy performed simultaneously with gastrectomy on postoperative complications in patients with gastric cancer undergoing surgery with the intention to treat.

UNLABELLED: Despite the growing understanding of the pathophysiological processes in the perioperative period and significant advancements in surgical techniques, operative treatment for gastric cancer remains a challenge for surgeons, especially because the primary procedure of total or nearly total gastrectomy must at times be extended by the resection of other organs. The aim of the study was to asses the influence of concomitant splenectomy in patients undergoing curative surgery for gastric cancer on postoperative complications. MATERIAL AND METHODS: The study population consisted of 258 patients who underwent surgical treatment for gastric cancer with the intention to treat. The study assessed the influence of extending the surgical intervention by splenectomy on postoperative complications, both general and surgical, including the most severe of these, i.e. oesophago-gastric anastomotic leakage, duodenal stump leakage and peritoneal fluid infections. RESULTS: Among the 258 gastric cancer patients receiving curative surgical treatment, the most common simultaneous intervention was splenectomy: 42/258 (16.3%), which was also accompanied by partial pancreatectomy in 8 cases. The number of surgical postoperative complications, major and minor, was similar in both subgroups: with and without splenectomy. Minor general complications, such as pyrexia with no clinically apparent reason, atelectasis, pneumonia and pleural effusion were statistically significantly more common in the subgroup with splenectomy (p=0.0001). CONCLUSION: Splenectomy performed concomitantly with gastrectomy for gastric cancer increases the risk of minor general complications. However, it does not increase the risk of severe surgical complications, such as oesophago-intestinal anastomotic leakage and does not increase the risk of death.

Coexistence of renal cell carcinoma of clear cell type with sarcomatoid cell type component and adrenal mature ganglioneuroma with myelolipoma - a case of 69-year-old female patient.

This report presents a case of 69-year-old woman, who was operated due to renal tumor. Apart from renal neoplasm, the adjacent adrenal gland contained another one tumor in medulla of the organ. The renal lesion was diagnosed renal cell carcinoma, clear cell type with undifferentiated cell sarcomatoid component. The adrenal neoplasm was composed of wavy S100-positive, Schwann-like cells and dispersed chromogranin A-reactive ganglion cells to be consistent with mature ganglioneuroma. It was accompanied by coexistent myelolipoma that contained hematopoietic cells including clearly visible megakaryocytes and foci of fat. To our knowledge, our paper is the first to report sporadic clear cell renal cell carcinoma with sarcomatoid cell type component and mature adrenal ganglioneuroma with myelolipoma in the same patient.

Iatrogenic bile duct injuries--clinical problems.

UNLABELLED: Laparoscopic cholecystectomy is one of the most frequently performed surgical procedures in surgical wards. Iatrogenic bile duct injuries (IBDI) incurred during the procedures are among postoperative complications that are most difficult to treat. The risk of bile duct injury is 0.2-0.4%, and their consequences are unpleasant both for the surgeon and for the patient. The aim of the study was analysis of iatrogenic bile duct injuries and methods of their repair, taking into consideration the circumstances, under which the injuries occur. MATERIAL AND METHODS: The study group consisted of 16 patients who had suffered IBDI during surgery. The analysed parameters included sex, age, indications for surgery, the setting of the surgical procedure and the type of bile duct injury. Additionally, the time of injury diagnosis, type of repair and treatment outcome were assessed. The IBDI analysis used the EAES classification of injuries. The time of IBDI repair was defined as immediate, early or late,depending on the time that had passed from the injury. The analysis included complications seen after bile duct repair. RESULTS: The study group consisted of 10 women and 6 men, aged 29-84. Patients underwent 6 classic cholecystectomies, 8 laparoscopic cholecystectomies, one gastrotomy to remove oesophageal prosthesis and one laparotomy due to peptic ulcer. IBDI was diagnosed intraoperatively in 4 patients. In 12 patients IBDI was diagnosed within 1-7 days. The diagnosis was based on endoscopic retrograde cholangiopancreatography and the results of biochemistry tests. According to the EAES classification, the injuries were of type 1 (4 patients), type 2 (8 patients), type 5 (3 patients) and type 6 (1 patients). Reconstruction procedures were performed during the same anaesthesia session in 3 patients, and in the early period in 13 patients. The main procedure was Roux-en-Y anastomosis (12 patients), with the remaining including bile-duct suturing over a T-tube (3 patients) and underpinning of an accessory bile duct in the pocket left after gallbladder removal (1 patient). The most common reconstruction complications included bile leak (3 patients), recurrent cholangitis (3 patients) and bile duct stricture (2 patients). Mortality in the study group was 12.5%. CONCLUSIONS: The procedures of laparoscopic and classic cholecystectomy are associated with a risk of IBDI, especially in the presence of inflammatory state of the gall-bladder. IBDI is a complex complication: its treatment poses a challenge for the operating surgeon, and even the most careful treatment adversely affects the patient's lifedue to complications.
