    Covid-19: A Retrospective Study About The Challenges for ERCP
    (2022) Cakcak, İbrahim Ethem; Kayabaş, Merve Yaren; Cansız, Sıla Nur; Yılmaz, Mustafa Numan; Albayrak, Doğan
    INTRODUCTION: We aimed to investigate the effects of Covid-19 on Endoscopic retrograde cholangiopancreatography (ERCP) and to investigate what should be considered in the next possible epidemic situations. METHODS: In our study, patients who applied to Trakya University School of Medicine, Department of General Surgery for ERCP (Endoscopic retrograde cholangiopancreatography) between March 2019 and March 2021 were evaluated, retrospectively. Percentages, mean, standard deviation, median and interquartile range were used as the descriptive statistics. Mann-Whitney U test was used for the variants which are contrary to the normal distribution range in the comparison of two groups. The relations between qualitative variants were studied by the Pearson Chi-Square test and Fisher’s Exact Chi-Square test. Significant value was determined as 0.05 for all statistical analyses. RESULTS: Prior to COVID-19, ERCP indications were in the order of stone (90.1%), stent removal (8%) and tumor (1.1%), while in the period of COVID-19, the ranking changed to stone (73.8%), tumor (13.7%), and stent removal (12.4%).. The diagnostic use of ERCP has been greatly reduced (from 0.7% to 0.0%). No perforation was detected in both periods, there was no bleeding, but a small increase (4.7% to 5.9%) was found in pancreatitis in the COVID-19 period. In the pre-COVID-19 period, stones were detected in 46.2% of the patients and all of them were successfully removed, but during the COVID-19 period, stones were detected in 50.6% of the patients and the stones could not be removed in 1.3% of the patients. DISCUSSION AND CONCLUSION: It was observed that the number of ERCPs decreased due to the delay in admissions to the hospital and the fear of coming to the hospital during the Covid-19 epidemic period, and the number of malignancies diagnosed with ERCP increased in this process. In such epidemic periods, more scheduled health services will provide better results for both patients and health personnel.

    Inflammatory markers in the prognosis of gastric cancer
    (2022) Cakcak, İbrahim Ethem; Aytin, Yusuf Emre; Koçyiğit, Beliz; Kayabaş, Merve Yaren; Cansız, Sıla Nur
    We aimed to investigate whether these parameters can determine the prognosis of gastric cancer. In our study, patients who applied to Trakya University School of Medicine, Department of General Surgery for surgical treatment with a diagnosis of gastric cancer between January 2015 and March 2021 were evaluated, retrospectively. In this study, we have 219 consecutive gastric cancer patients who applied for surgical treatment between January 2015 and March 2021. There are 156 (71.2%) male patients and 63 (28.7%) female patients. The mean age is 65.6±11.2. 158 (72%) of our patients were over the age of 60. When each TNM stage was compared with each other, a statistically significant difference was found in the NLR, PLR, PNI, SIRI, and SII parameters. There was a statistically significant difference between the GPS when we compare the early stage and the advanced stage cancer. In our study, we showed that high SIRI, SII, NLR, PLR, and GPS as inflammatory and nutritional markers and low PNI value may be negative predictive factors for prognosis in gastric cancer patients.
