    Severe disease MESHD caused by the SARS-CoV coronavirus MESHD is characterized by patients presenting with respiratory distress HP associated with a systemic inflammatory response syndrome (cytokine storm). Sixteen to thirty percent of COVID-19 patients also have gastrointestinal symptoms. Here we present three cases of COVID-19 who developed colonic ischemia MESHD. Three males TRANS aged TRANS 76, 68 and 56 with respiratory distress HP and receiving mechanical ventilation presented episodes of rectal bleeding MESHD, abdominal distension and signs of peritoneal irritation. Endoscopy (case 1) and computed tomography angiography revealed colonic ischemia MESHD and pneumoperitoneum MESHD.One patient (case 2) underwent surgery in which perforation of the gangrenous MESHD cecum and colonic ischemia MESHD was confirmed.In all three patients D-dimer levels were markedly increased (2170, 2100 and 7360 ng/mL). All three patients died shortly after diagnosis.In severe COVID-19 disease, the pathogenic cause has increasingly become attributed to the development of disseminated intravascular coagulation HP intravascular coagulation MESHD secondary to the systemic inflammatory response.

    Background: The SARS-CoV2 virus pandemic pandemic MESHD has been characterized for its rapid global dispersion. Obesity HP is an independent risk factor for the most severe cases of COVID -19. The impact in Argentina differs from others since it was able to anticipate public health interventions in order to flatten the contagion curve. Early quarantine achieved better control of the pandemic and, following the recommendations of scientific societies in countries with higher affectation, elective bariatric surgeries (BS) and in-person consults were suspended. Objective: Bariatric surgeons were surveyed to assess the impact of the pandemic and the measures undertaken on the practice of BS in Argentina.Method: Between April 17 and 21, 2020, an online survey in Google forms was disseminated to bariatric surgeons residing in Argentina. It consists of 40 specific and non-specific questions regarding BS practice and COVID pandemic. Consent to participate was obtained from surgeons by completing the survey.Results: 83 surgeons averaging 47.17 years of age TRANS responded the survey. Together they performed 10515 BS in 2019. More than 65% stated that more than 50% of their income derives from this activity, and more than 40% depend on more than 75% of it. The average hospital stay was 1.6 days and 85% reported using Intensive Care Unit (ICU) in less than 1% of their patients. According to the scores of hospital affectation issued by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), 54% reported being in Phase I and 34% had not yet been affected by the pandemic. All, except one, suspended the elective BS 7.7 days on average before the appearance of the first local case. 95.7% offer virtual consults, but 48% obtain no retribution for them. 26% would consider performing BS without a previous endoscopic evaluation.90% of the surgeons surveyed (75) continue performing other types of surgeries via laparoscopy. In case of operating a patient without suspected SARS-CoV-2 virus infection MESHD, 80% would use N95 masks and 56.6% would use face protection shields; two thirds would use smoke filters for the pneumoperitoneum MESHD and only 10.8% would continue with the usual protection measures. To restart the elective activity, 56.6% proposed that the hospital should be in phase 0 or I, that the patient should meet certain characteristics for their selection and that the scientific society must recommend the way to restart of the activity.Patient selection criteria with greater consensus were testing to rule out asymptomatic TRANS COVID-positive patients, epidemiology, absence of chronic lung disease MESHD chronic lung disease HP, age TRANS under 60, and immunological integrity. 19.2% regard sleeve gastrectomy as the ideal BS during the pandemic, and 88% of the surgeons would not change their chosen BS technique based on infection risk TRANS infection risk TRANS. Conclusion: Elective BS is currently suspended in Argentina, although epidemiologically the conditions in the country are not unfavorable. Economic impact for those involved is significant. Short-term vision is pessimistic, but recommendations originating from the scientific societies that nucleate them are expected in order to guide health authorities towards appropriate regulations suitable for the local practice.
