ABSTRACT: Infection with the SARS-CoV-2 virus seems to contribute significantly to increased postoperative complications and mortality after emergency surgical procedures. Additionally, the fear of COVID-19 contagion delays the consultation of patients, resulting in the deterioration of their acute diseases by the time of consultation. In the specific case of urgent digestive surgery patients, both factors significantly worsen the postoperative course and prognosis. Main working hypothesis: infection by COVID-19 increases postoperative 30-day-mortality for any cause in patients submitted to emergency/urgent general or gastrointestinal surgery. Likewise, hospital collapse during the first wave of the COVID-19 pandemic increased 30-day-mortality for any cause. Hence, the main objective of this study is to estimate the cumulative incidence of mortality at 30-days-after-surgery. Secondary objectives are: to estimate the cumulative incidence of postoperative complications and to develop a specific postoperative risk propensity model for COVID-19-infected patients.A multicenter, observational retrospective cohort study (COVID-CIR-study) will be carried out in consecutive patients operated on for urgent digestive pathology. Two cohorts will be defined: the "pandemic" cohort, which will include all patients (classified as COVID-19-positive or -negative) operated on for emergency digestive pathology during the months of March to June 2020; and the "control" cohort, which will include all patients operated on for emergency digestive pathology during the months of March to June 2019. Information will be gathered on demographic characteristics, clinical and analytical parameters, scores on the usual prognostic scales for quality management in a General Surgery service (POSSUM, P-POSSUM and LUCENTUM scores), prognostic factors applicable to all patients, specific prognostic factors for patients infected with SARS-CoV-2, postoperative morbidity and mortality (at 30 and 90 postoperative days). The main objective is to estimate the cumulative incidence of mortality at 30 days after surgery. As secondary objectives, to estimate the cumulative incidence of postoperative complications and to develop a specific postoperative risk propensity model for SARS-CoV-2 infected patients.The protocol (version1.0, April 20th 2020) was approved by the local Institutional Review Board (Ethic-and-Clinical-Investigation-Committee, code PR169/20, date 05/05/20). The study findings will be submitted to peer-reviewed journals and presented at relevant national and international scientific Identifier: NCT04479150 (July 21, 2020).

There is an increasing number of confirmed cases and deaths caused by the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) contributing to the Coronavirus disease 2019 (COVID-19) pandemic. At this point, the need for further disease characterization is critical. COVID-19 is well established as a respiratory tract pathogen; however, recent studies have shown an increasing number of patients reporting gastrointestinal manifestations such as diarrhea, nausea, vomiting, and abdominal pain. The time from onset of gastrointestinal symptoms to hospital presentation is often delayed compared to that of respiratory symptoms. It has been noted that SARS-CoV-2 RNA can be detected in fecal matter for an extended period of time, even after respiratory samples have tested negative and patients are asymptomatic. In this article, SARS-CoV-2 and its disease COVID-19 will be reviewed with consideration of the latest literature about gastrointestinal symptomatology, the mechanisms by which the virus may inflict damage, and the possibility of viral replication contributing to a fecal-oral route of transmission.
