Background: The utilization of intraoperative ultrasound (IOUS) in breast cancer surgery is a relatively new concept in surgical oncology. Over the last few decades, the field of breast cancer surgery has been striving for a more rational approach, directing its efforts towards removing the tumor entirely yet sparing tissue and structures not infiltrated by tumor cells. Further progress in objectivity and optimization of breast cancer excision is possible if we make the tumor and surrounding tissue visible and measurable in real time, during the course of the operation; IOUS seems to be the optimal solution to this complex requirement. IOUS was introduced into clinical practice as a device for visualization of non-palpable tumors, and compared to wire-guided localization (WGL), IOUS was always at least a viable, or much better alternative, in terms of both precision in identification and resection and for patients' and surgeons' comfort. In recent years, intraoperative ultrasound has been used in the surgery of palpable tumors to optimize resection procedures and overcome the disadvantages of classic palpation guided surgery. Objective: The aim of this review is to show the role of IOUS in contemporary breast cancer surgery and its changes over time. Methods: A PubMed database comprehensive search was conducted to identify all relevant articles according to assigned key words. Conclusion: Over time, the use of IOUS has been transformed from being the means of localizing non-palpable lesions to an instrument yielding a reduced number of positive resection margins, with a smaller volume of healthy breast tissue excided around tumor, by making the excision of the tumor optimal and objectively measurable. © 2018 The Author(s).

Introduction/Objective Bile duct injuries represent a devastating and potentially life-threatening consequence of cholecystectomy. Although most cholecystectomies are currently performed laparoscopically, some complex cases require an open approach. The aim of this report is to present and analyze a single center experience regarding the management of these injuries. Methods A retrospective study was conducted in a tertiary referral institution. During a 13-year period, we identified a total of 64 patients. Only patients requiring surgical reconstruction to repair bile duct injuries were included in the study. Patients were grouped according to the type of surgical approach, i.e. laparoscopic or open cholecystectomy. Results Out of 64 patients with bile duct injuries, 38 (59.4%) incurred the injuries during open and 26 (40.6%) during laparoscopic cholecystectomy. No differences between the groups were observed concerning the time of bile duct injury diagnosis, type of injury, incidence of concomitant vascular and bile duct injuries, type of reconstruction procedure or complication rates after the primary intervention. The latency of bile duct injury management was found to differ between the study groups. In the open cholecystectomy group, bile duct injuries were managed significantly later than in the laparoscopic one. Conclusion The results suggest that bile duct injuries occur with equal frequency after laparoscopic as well as open cholecystectomy. However, injuries are managed later after open than after laparoscopic cholecystectomy. Tertiary centers have satisfactory outcomes of major bile duct injury reconstruction, with low rates of both morbidity and mortality. © 2019, Serbia Medical Society. All rights reserved.

Objective: We aimed to compare mortality and complication rates in patients treated for obstructive jaundice before and during the COVID-19 pandemic in a tertiary care center in Serbia. Methods: We conducted a retrospective cohort study among a first group of patients treated between 1 January 2017 and 1 January 2019. The second group was treated between 1 March 2020 and 1 March 2022. Results: The first group comprised 35 patients, and the second group (in which all patients were SARS-CoV-2 positive) included 18 patients; 37 and 16 patients were treated for malignant and benign diseases, respectively. The groups did not differ significantly regarding the diagnoses and treatment received. The second group showed significantly higher aspartate aminotransferase levels and lower white blood cell, C-reactive protein, and interleukin 6 levels. Mortality and complication rates did not differ significantly between groups. All deceased patients in the second group had significant radiologic findings associated with COVID-19 pneumonia. Conclusions: COVID-19 infection is a risk factor in treating obstructive jaundice. This study illustrates the potential influence of COVID-19 on mortality after obstructive jaundice treatment. COVID-19 pneumonia may be a significant risk factor for mortality in patients treated for obstructive jaundice. © The Author(s) 2023.
