    Abstract Background: Over-the-scope clip (OTSC) devices are now widely used by endoscopists for gastrointestinal bleeding, perforation, or leakage. The present study aims to examine the therapeutic success rate of this technique.
    Methods: This was a single-center, retrospective study. In this study, 23 patients with gastrointestinal bleeding, leakage, or perforation were included. The procedure was performed by an experienced endoscopist.
    Results: Of the patients with an upper gastrointestinal tract defect, six had a perforation and there was one case of anastomosis leakage. Eight patients had a perforation in the lower gastrointestinal tract, and there were two cases of anastomosis leakage. Bleeding was detected in only six patients and all of them were upper gastrointestinal bleeding. Anastomosis leaks, perforations, and bleeding were treated with OTSC and additional procedures. The success rate of OTSC clipping alone was 56.5%. However, the success rate was 86.9% with additional therapeutic procedures (clamp, stent, sclerotherapy). Analysis according to categories of bleeding, perforation, and anastomosis leak revealed that the success rate of the clip application in bleeding was significantly higher than that of perforation or anastomosis leak (p=0.002). The median length of stay in the hospital was five days (min-max: 2-30 days). There were no complications associated with the OTSC procedure.
    Conclusion: OTSC is a safe and effective method for the management of gastrointestinal bleeding, perforation, or anastomosis leak.

    Abstract Background: We aim to assess the effects of gastric posterior fixation with fibrin sealant in laparoscopic sleeve gastrectomy in aspects of 12th-month body mass index and gastric volume.
    Methods: The patients who underwent laparoscopic sleeve gastrectomy between January 2019 and February 2021 were divided into two groups preoperatively. The first 75 patients were appointed to the posterior fixation group, and the second 75 were to the control group. Changes in gastric volume and body mass index were assessed in the postoperative 12th month.
    Results: There were 110 patients in the final analysis. Fifty-four patients had posterior fixation, and 56 had only laparoscopic sleeve gastrectomy. The posterior fixation group was superior in terms of total weight loss rate (39.1% vs. 34.5%, p<0.001) and less gastric volume increase rate (39.8% vs. 164.7%, p<0.001) in the postoperative 12th month.
    Conclusion: Our study suggests that posterior fixation with fibrin sealant in laparoscopic sleeve gastrectomy is a promising method for preventing weight regain and creating a need for revision surgery.

    Abstract Objective: The aim of our study is to determine the risk of coinfection with COVID-19 due to the high prevalence of viral agents in Istanbul in autumn (September, October, and November) and winter (December and January) and to investigate the effects of age, gender, season and clinical features on the development of coinfection with COVID-19.
    Methods: In the routine studies of our hospital, COVID-19, reverse transcriptase polymerase chain reaction (RTA kit, Turkiye) and Multiplex PCR Bio-Fire (Bio Merieux Company, France) methods were studied from the nasopharyngeal swab sample and the data were recorded. A total of 400 people with a mean age (7.91±17.80) were included in the study by retrospective scanning.
    Results: Considering the virus distribution, Respiratory syncytial virus (RSV), COVID-19, rhino/entero virus did not show a significant difference in autumn and winter, while H. metapneumovirus, adeno virus, influenza A significantly higher rates were observed in winter months. Parainfluenza (1, 2, 3, 4) and Corona OC43 were detected at a higher rate in autumn compared to other viruses. Double and triple coinfection rates with other viral agents were high for 2 years and younger.
    Conclusion: The risk of coinfection of COVID-19 with influenza A, RSV, parainfluenza, and rhino/entero virus was found to be higher than other viral agents. Especially in winter, the risk of coinfection with influenza A and COVID-19 increases. In terms of treatment management, coinfection should be investigated in risky patients and influenza a vaccine should be offered to risky groups.

    Title translation ERCP öyküsü akut kolesistitte subtotal kolesistektomi oranını değiştirir mi?
    Abstract Background: Acute cholecystitis is one of the most common emergent surgeries. As a safe alternative in challenging operations, laparoscopic subtotal cholecystectomy (LSC) is widely used. We questioned whether the results in acute cholecystitis cases changed with a history of endoscopic retrograde cholangiopancreatography (ERCP). When we searched the literature, we could not find a study focusing on the subtotal cholestectomy results in acute cholecystitis. In our study, we aimed to investigate whether the history of ERCP affects the rates of subtotal cholecystectomy (SC) in acute cholecystitis.
    Methods: The results of patients (n=470) who underwent surgery for acute cholecystitis at our clinic between 2016 and 2019 were retrospectively evaluated. The patients were divided into two groups according to their history of ERCP. The primary outcome was the SC rate. The secondary outcomes were conversion to open, postoperative complications, serious complications, operative duration, and length of hospital stay.
    Results: The standard group included 437 patients, whereas the ERCP group included 33 patients. A total of 16 patients underwent SC, with 15 in the standard group and 1 in the ERCP group. There was no significant difference in terms of SC rates between groups (P=0.902). While four cases of operation were completed with conversion to open in the non-ERCP group, no conversion was seen in the ERCP group (P=0.581). No significant differences were detected between the groups in terms of complications, serious compli-cations, operation duration, length of hospital stay, and mortality.
    Conclusion: The results of this study showed that ERCP is not related to an increased rate of SC and conversion in patients with acute cholecystitis. Laparoscopic cholecystectomy for acute cholecystitis can be safely performed in patients with a history of ERCP. LSC is a safe procedure in challenging patients, and fenestrating SC can be preferred to avoid hazardous consequences in such cases.

    Abstract Background: Hartmann's procedure (HP) is commonly applied to resolve acute clinical conditions in most cases with colonic obstruction or perforation. HP and the closure of the end colostomy are associated with high morbidity-mortality rates. In our study, we aimed to report our clinical experience in HP.
    Methods: Demographic data and outcomes of Hartmann procedures performed between 2015 and 2023 were retrospectively reviewed.
    Results: The median age of our study was 63 (18-94) years; 65 of the patients were female, and 97 were male. Colorectal malig-nancies were the primary etiology in 50% of patients who underwent HP, with 70% presenting with obstruction and 30% with perfora-tion. Two-thirds of the patients were American Society of Anesthesiologists-2 or higher. Postoperative complications did not develop in 74.7% of patients. Our mortality rate was 33.3%. The colostomy was closed in 59 patients during an average 2-year follow-up. The median closure time was 311 (57-1319) days. A stapler was used in 89.8% of patients during the closure. A diverting ileostomy was created in only two patients. The median hospital stay was 8 (5-70) days. Post-operative complications did not develop in 25.4% of patients, while four patients died.
    Conclusion: In our population, HP was more commonly performed for colorectal cancer. The procedure and closure of the ostomy result in low stoma closure rates, high morbidity, and mortality rates, as well as surgical difficulties.

    Abstract Background/aim: The present study aimed to create a decision tree for the identification of clinical, laboratory and radiological data of individuals with COVID-19 diagnosis or suspicion of Covid-19 in the Intensive Care Units of a Training and Research Hospital of the Ministry of Health on the European side of the city of Istanbul.
    Materials and methods: The present study, which had a retrospective and sectional design, covered all the 97 patients treated with Covid-19 diagnosis or suspicion of COVID-19 in the intensive care unit between 12 March and 30 April 2020. In all cases who had symptoms admitted to the COVID-19 clinic, nasal swab samples were taken and thoracic CT was performed when considered necessary by the physician, radiological findings were interpreted, clinical and laboratory data were included to create the decision tree.
    Results: A total of 61 (21 women, 40 men) of the cases included in the study died, and 36 were discharged with a cure from the intensive care process. By using the decision tree algorithm created in this study, dead cases will be predicted at a rate of 95%, and those who survive will be predicted at a rate of 81%. The overall accuracy rate of the model was found at 90%.
    Conclusions: There were no differences in terms of gender between dead and live patients. Those who died were older, had lower MON, MPV, and had higher D-Dimer values than those who survived.

    Abstract Introduction: Endoscopic drainage should preferably be tried unless the abscess caused by the anastomotic leak is generalized and disseminated into the abdominal cavity. The aim of this study was to evaluate the results of patients treated with EndoVac.
    Patient and methods: The medical records of patients who underwent low anterior resection and were treated using the EndoVac therapy system due to the detection of an anastomotic leak were retrospectively evaluated.
    Results: Thirty-three of the patients with detection of anastomotic leaks were treated using EndoVac therapy system. The mean number of application of the EndoVac therapy system was 5.8 (1 to 12) for each patient. Mean duration of hospitalization of the patients was 24.5 (9 to 92) days. Five patients underwent a second operation during the follow-up period after application of the EndoVac therapy system. In our study, the number of patients recovering without the need for additional treatment is 30 (30/33). Our success rate was 90.1%.
    Conclusions: The EndoVac therapy system is an alternative and helpful system in the treatment of colorectal anastomotic leaks without reoperation needed. It can also prevent permanent stoma.

    Abstract Aim: To determine whether convalescent angiotensin (1-7) peptide replacement therapy with plasma (peptide plasma) transfusion can be beneficial in the treatment of critically ill patients with severe coronavirus 2 (SARS-CoV-2) infection.
    Study design: Case series of 9 critically ill patients with laboratory-confirmed COVID-19 who met the following criteria: severe pneumonia with rapid progression and continuously high viral load despite antiviral treatment. Peptide plasma: Plasma with angiotensin (1-7) content 8-10 times higher than healthy plasma donors was obtained from suitable donors. Peptide plasma transfusion was applied to 9 patients whose clinical status and/or laboratory profile deteriorated and who needed intensive care for 2 days.
    Results: In our COVID-19 cases, favipiravir, low molecular weight heparin treatment, which is included in the treatment protocol of the ministry of health, was started. Nine patients with oxygen saturation of 93% and below despite nasal oxygen support, whose clinical and/or laboratory deteriorated, were identified. The youngest of the cases was 36 years old, and the oldest patient was 85 years old. 6 of the 9 cases had male gender. 3 cases had been smoking for more than 10 years. 4 cases had at least one chronic disease. In all of our cases, SARS CoV2 lung involvement was bilateral and peptide plasma therapy was administered in cases when oxygen saturation was 93% and below despite nasal oxygen support of 5 liters/minute and above, and intensive care was required. Although it was not reflected in the laboratory parameters in the early period, 8 patients whose saturations improved with treatment were discharged without the need for intensive care. However, a similar response was not obtained in one case. Oxygen requirement increased gradually and, he died in intensive care process. An increase of the platelet count was observed in all cases following the peptide plasma treatment.
    Conclusion: In this preliminary case series of 9 critically ill patients with COVID-19, administration of plasma containing angiotensin (1-7) was followed by improvement in their clinical status. The limited sample size and study design preclude a definitive statement about the potential effectiveness of this treatment, and these observations require evaluation in clinical trials.
