ABSTRACT

Background: Gallbladder and biliary tract infections are diseases with high mortality rates if they are not treated properly. Microbiological evaluation of perioperatively collected samples both ensures proper treatment of patients and guides empirical treatment due to the determination of microorganism susceptibility. Aims: This study aimed to isolate the microorganisms in bile cultures from patients who underwent cholecystectomy and to determine sensitivity results of these microorganisms. Methods: This study was a multi-center and prospective design, included 360 patients, and was performed between 2019 and 2020. Culture results of bile taken during cholecystectomy were evaluated. Results: Bacterial growth was found in the bile cultures of 84 out of 360 (23.3%) patients. Patients were divided into two groups according to whether they had risk factors for resistant microorganisms or not. While Escherichia coli (n = 11, 13%), Enterococcus spp. (n = 8, 9.5%), and Enterobacter spp. (n = 4, 4.7%) were detected most frequently in patients without risk. Staphylococcus spp. (n = 17, 20.2%), Enterococcus spp. (n = 16, 19%), and E. coli (n = 8, 9.5%) were the most frequently found microorganism at-risk patients. In multivariate analysis, bile culture positivity was found higher in patients who had history of biliary disease (p = 0.004), operation performed concurrently with a cholecystectomy (p = 0.035), and high rate of polymorphonuclear leukocytes (PNL) in total leukocyte count (p = 0.001). Conclusions: Our study shows that when starting empirical antibiotic treatment for bile ducts, whether patients are at risk for the development of resistant bacterial infection should be evaluated after which antibiotic selection should be made accordingly.(AU)

ABSTRACT

Malignant peripheral nerve sheath tumors (MPNST) are rare. Although they originate from Schwann cells or pluripotent neural crest cells, they constitute less than 10% of all soft tissue sarcomas and more than 60% develop on the basis of neurofibromatosis. It is difficult to diagnose MPNST. Although it mostly occurs in the head and neck region or upper extremities, only 1% of cases are located in the retroperitoneal region. The main treatment is surgery, but survival results are not satisfactory even after surgery with R0 resection. They are not sensitive to chemotherapy and radiotherapy and tend to recur locally. The mass detected by imaging in a 57-year-old male patient who admitted to hospital with the complaint of abdominal pain was excised with clear surgical margins. The tumor was located in the left upper quadrant of the abdomen and seemed to invade the pancreas and left kidney in the computed tomography images. The patient had no history of neurofibromatosis or radiation. In this study, it was aimed to present our case diagnosed with retroperitoneal MPNST and treated with multiorgan resection, which is a rare entity, and to increase the awareness of clinicians about the diagnosis, treatment and prognosis of this rare tumor.

ABSTRACT

ABSTRACT BACKGROUND: The coronavirus disease-19 (COVID-19) pandemic has changed the course of diseases that require emergency surgery. OBJECTIVE: To evaluate the effect of the COVID-19 pandemic on colorectal cancer disease stage. DESIGN AND SETTING: Retrospective analysis in the city of Rize, Turkey. METHODS: This was a comparative analysis on two groups of patients with various symptoms who underwent surgical colorectal cancer treatment. Group 1 comprised patients operated between March 11, 2019, and December 31, 2019; while group 2 comprised patients at the same time of the year during the COVID-19 pandemic. RESULTS: Groups 1 and 2 included 56 and 48 patients, respectively. The rate of presentation to the emergency service was higher in Group 2 (P < 0.02). The stage of the pathological lymph nodes and the rate of liver metastasis was higher in Group 2 (P < 0.004 and P < 0.041, respectively). The disease stage was found to be more advanced in Group 2 (P < 0.005). The rate of postoperative complications was higher in Group 2 (P < 0.014). CONCLUSION: The presentation of patients with suspicious findings to the hospital was delayed, due both to the fear of catching COVID-19 and to the pandemic precautions that were proposed and implemented by healthcare authorities worldwide. Among the patients who presented to the hospital with emergency complaints and in whom colorectal cancer was detected, their disease was at a more advanced stage and thus a higher number of emergency oncological surgical procedures were performed on those patients.

ABSTRACT

Background/aim: Operative bleeding is one of the major determinants of outcome in liver surgery. This study aimed to describe the impact of intraoperative blood loss on the postoperative course of liver resection (LR). Materials and methods: The data of 257 patients who were treated with LR between January 2007 and October 2018 were retrospectively analyzed. LRs were performed via intermittent portal triad clamping (PTC) under low central venous pressure. Results: LRs were performed for 67.7% of patients with a malignant disease and 32.3% of patients with a benign disease. Major LR was performed in 89 patients (34.6%). The mean PTC period was 20.32 min (±13.7). The median intraoperative bleeding amount was 200 mL (5­3500 mL), the 30-day mortality rate was 4.3%, and the morbidity rate was 31.9%. The hospital stay (p = 0.002), morbidity (p = 0.009), and 30-day mortality (p = 0.041) of patients with a bleeding amount of more than 500 mL significantly increased. Conclusion: Surgeons should consider the adverse effects of intraoperative bleeding during liver resection on patients' outcome. Favorable outcomes would be obtained with diligent postoperative care.

ABSTRACT

This study aimed to investigate clinical characteristics of hepatocellular carcinoma and the outcome of our aggressive treatment policy which follows the Barcelona Clinic Liver Cancer (BCLC) guidance. In this study, we retrospectively analyzed data of 102 patients who were treated for hepatocellular carcinoma between January 2007 and October 2016. Male predominance (81.4%) and a median age of 61 years were observed. Cirrhosis was evident in 88.2 per cent of patients. Viral hepatitis (77.5%) was the most common underlying etiology. The majority of our patients (71.6%) were in BCLC B and C stages. Liver resection was performed in 53.4 per cent of patients in those stages. Transarterial chemoembolization was the leading interventional treatment. Overall survival rates at three and five years were 75 per cent and 75 per cent in BCLC 0, 69 per cent and 58 per cent in BCLC A, 50 per cent and 41 per cent in BCLC B, and 11 per cent and 11 per cent in BCLC C, respectively. The BCLC treatment algorithm should consider the role of liver resection also for intermediate stages.
