Introduction: Endometriosis is a benign condition affecting females of reproductive age. Although intestinal endometriosis is common, it is rarely manifested as an acute bowel obstruction secondary to ileal endometriosis. Enteric endometriosis should be considered as a differential diagnosis when assessing females of reproductive age with acute small bowel obstruction. Case Outline: A 41-year-old woman presented with symptoms and signs of an acute small bowel obstruction requiring emergency surgery. A small bowel resection was performed with end-to-end anastomosis. Histological examination demonstrated endometriosis with fibrosis and stricture of the ileal segment. This case is important to report as it highlights the diagnostic difficulty this particular condition presents to an emergency surgeon. Conclusion: In the differential diagnosis, endometriosis should be taken into consideration when assessing females of reproductive age who present with abdominal pain and small bowel obstruction. © 2012, Serbia Medical Society.

Introduction/Objective The development of acute insulin resistance after surgery intervention is associated with the type and magnitude of operation and tissue injury. The aim of our study was to compare insulin sensitivity assessed by homeostatic model assessment of insulin resistance (HOMA-IR) and C-reactive protein (CRP) before and after laparoscopic and open cholecystectomy during seven days follow-up. Methods In total, 92 patients were divided into two groups: laparoscopic cholecystectomy (Group 1) (n = 61) and open cholecystectomy (Group 2) (n = 31). Glucose, insulin and CRP levels were measured at day 0 and at postoperative days one, three and seven. Glucose, insulin and CRP were determined using commercial assay on Roche Cobas 6000 automated analyzer (Roche Diagnostics, Manheim, Germany). Results There was no statistical difference between studied groups concerning age (p = 0.626), body mass index (p = 0.548), glucose (p = 0.947), insulin (p = 0.212), HOMA-IR (p = 0.390) and CRP (p = 0.546) at day 0. At day one, higher values of CRP were found in group 2 compared with group 1 (p = 0.046). At day three, significantly higher values of glucose and HOMA-IR were found in group 2 compared with group 1 (p = 0.025, p = 0.036, respectively). Conclusion Increase in CRP precedes deterioration of insulin sensitivity measured by HOMA-IR after cholecystectomy. Impairment of insulin sensitivity was more pronounced at postoperative day three in group with open cholecystectomy. On the basis of our results, laparoscopic cholecystectomy induced less impairment in insulin sensitivity and lower inflammatory response. © 2023, Serbia Medical Society. All rights reserved.

Background and aims: The present study attempted to identify the diagnostic significance of procalcitonin (PCT) in acute abdominal conditions as well as the range of concentrations relating to diagnosis of abdominal sepsis. Materials and methods: This was prospective clinical study. The study included 98 consecutive patients with acute abdominal conditions, divided in sepsis and systemic inflammatory response syndrome (SIRS) group. Results: PCT concentrations on admission were significantly higher in the sepsis group than in the SIRS group (median [interquartile range] 2.32 [7.41] vs 0.45 ng/ml [2.62]). A cutoff value of 1.1 ng/ml yielded 72.4% sensitivity and 62.5% specificity. In a group of patients with abdominal symptoms lasting for more than 24 h, a cut-off value of 1.1 ng/ml yielded higher sensitivity (82.9%) and higher specificity (77.3%). Conclusion: Our results suggest that PCT measurements may be useful for early, preoperative diagnosis of abdominal sepsis. © 2007 Springer-Verlag.

Sepsis is a medical emergency and therefore requires early identification and immediate management, which is not a matter of hours, but minutes. Since the first definition in 1991, sepsis remains a major challenge for clinicians and scientists. Despite significant advances in technology and therapy, mortality and cost of treatment are unacceptably high. Septic shock is the leading cause of mortality in critically ill patients. Cognitive impairment and functional disability were observed after survivors’ long term follow-up. Since its foundation in 2002, Surviving Sepsis Campaign aims to implement global strategies and to raise awareness of the challenges associated with sepsis. The implementation of guidelines and sepsis care bundles resulted in significant decrease in mortality. Hospital mortality is lower in hospitals with high versus low bundle compliance. Still, epidemiological data for sepsis are missing for low-and middle-income countries. © 2020, Serbia Medical Society. All rights reserved.

Introduction Despite the fact that treatment of liver injuries has dramatically evolved, severe liver traumas in polytraumatic patients still have a significant morbidity and mortality. Objective The purpose of this study was to determine the options for surgical management of severe liver trauma as well as the outcome. Methods In this retrospective study 70 polytraumatic patients with severe (American Association for the Surgery of Trauma [AAST] grade III–V) blunt liver injuries were operated on at the Clinic for Emergency Surgery. Results Mean age of patients was 48.26±16.80 years; 82.8% of patients were male. Road traffic accident was the leading cause of trauma, seen in 63 patients (90.0%). Primary repair was performed in 36 patients (51.4%), while damage control with perihepatic packing was done in 34 (48.6%). Complications related to the liver occurred in 14 patients (20.0%). Liver related mortality was 17.1%. Non-survivors had a significantly higher AAST grade (p=0.0001), higher aspartate aminotransferase level (p=0.01), lower hemoglobin level (p=0.0001), associated brain injury (p=0.0001), perioperative complications (p=0.001) and higher transfusion score (p=0.0001). The most common cause of mortality in the “early period” was uncontrolled bleeding, in the “late period” mortality was caused by sepsis and acute respiratory distress syndrome. Conclusion Patients with high-grade liver trauma who present with hemorrhagic shock and associated severe injury should be managed operatively. Mortality from liver trauma is high for patients with higher AAST grade of injury, associated brain injury and massive transfusion score. © 2015, Serbia Medical Society. All rights reserved.

Background: Severe liver injury in trauma patients still accounts for significant morbidity and mortality. Operative techniques in liver trauma are some of the most challenging. They include the broad and complex area, from damage control to liver resection. Material and method: This is a retrospective study of 121 trauma patients with hepatic trauma American Association for Surgery of Trauma (AAST) grade III-V who have undergone surgery. Indications for surgery include refractory hypotension not responding to resuscitation due to uncontrolled hemorrhage from liver trauma; massive hemoperitonem on Focused assessment by ultrasound for trauma (FAST) and/or Diagnostic peritoneal lavage (DPL) as well as Multislice Computed Tomography (MSCT) findings of the severe liver injury and major vascular injuries with active bleeding. Results: Non-survivors have significantly higher AAST grade of liver injury and higher Injury Severity Score (ISS) (p=0.000; p=0.0001). Non-survivors have significant hypotension on arrival and lower Glasgow Coma Scale (GCS) on admission (p=0.000; p=0.0001). Definitive hepatic repair was performed in 62(51.2%) patient. Damage Control, liver packing and planned re-laparotomy after 48h were used in 59(48.8%). There was no statistically significant difference in terms of the surgical approach. There was significant difference in the amount of red blood cells (RBC) transfusion in the first 24h between survivors and non-survivors (p=0.001). Overall mortality rate was 33.1%. Regarding complications non-survivors had significantly prolonged bleeding and higher rate of Acute respiratory distress syndrome (ARDS) (p=0.0001; p=0.0001), while survivors had significantly higher rate of pleural effusion (p=0.0001). Conclusion: All efforts in the treatment of severe liver injuries should be directed to the rapid and effective control of bleeding, because uncontrollable hemorrhage is the cause of early death and it requires massive blood transfusion, all of which contributes to the late fatal complication. © 2015 Doklestić et al.

Introduction/Objective Acute pancreatitis (AP) is a relatively common disease which in most patients has favorable course. However, in approximately 20% patients, the course of the disease is more severe with high mortality (40–50%). The evaluation of disease severity is now primarily based on protocols that includes clinical, laboratory, and radiographic diagnostic procedures, APACHE II score, Ranson score, CT index, and CT necrosis score. Key cells in the immunopathogenesis of AP are T-lymphocytes, and recent studies indicate the role of Th2 and their effector cytokines: interleukin (IL)-4 and interleukin (IL)-5. The purpose of our study was to determine the potential clinical value of IL-4 and IL-5 as biochemical markers for predicting development of severe, necrotizing form of acute pancreatitis with systemic complication such as systemic inflammatory response syndrome (SIRS). Methods This prospective study included 240 patients hospitalized at The Clinic for Emergency Surgery of Clinical Center of Serbia as AP. Levels of IL-4 and IL-5 in serum were detected using commercial Bender Med Systems (BMS716FF) kits. Results IL-4 and IL-5 were statistically significant increased on the second day of hospitalization with maximum values on the third day. In patients with severe AP complicated with necrosis and/or sepsis values were rising all through the seventh day. Conclusion Levels of IL-4 and IL-5 in peripheral blood correlate with SIRS, Ranson score and clinical outcome in AP patients, therefore these cytokines are potential early biomarkers of disease progression and related complications. © 2021, Serbia Medical Society.
