At the end of 2019 in Wuhan, China, a novel coronavirus was reported. Out of seven subtypes of human-infective coronaviruses, the beta-coronaviruses lead to potentially dangerous diseases. The massive dissemination of COVID-19 has contributed to an outbreak in China which now extends worldwide. A total of 626343 cases globally have so far been diagnosed (4).
Furthermore, irrespective of the unsatisfactory performance of the real-time reverse transcription-polymerase chain reaction (RT-PCR) test, some doctors announced that the above-mentioned patient was infected with COVID-19, based on the findings of the patient's CT scan, clinical signs, and laboratory tests.
The major symptoms of COVID-19 infection are primarily cough, fever, and dyspnea as shown by the first reports in China (5). Similarly, throughout the second day after the operation, our patient showed moderate fever, dyspnea, and moderate hypoxemia. Bilateral infiltrating pneumonia was concurrently shown by the chest X-ray. Also, the way the patient's symptoms developed resembled those stated in the WHO announcement in which the COVID-19 most prevalent signs include fever, tiredness, and dry cough. Although typically mild with a gradual beginning, there might be also symptoms like aches and pains, runny nose, nasal congestion, diarrhea or sore throat (5). In addition, China studies using high-resolution CT showed that all patients reported signs of bilateral pneumonia of varying severity, including those in mild cases, suggesting that if the respiratory tract is lower, it provides a more suitable location for the replication of SARS-CoV-2 (6, 7). Clinical characteristics of 2019 novel coronavirus (2019-nCoV) pneumonia involve fever, dry cough, and asthenia. Nasal obstruction, runny nose, and diarrhea are usually experienced in few numbers of cases. In severe cases of the disease, dyspnea normally arises one week after the infection is developed, whereas ARDS, metabolic acidosis, septic shock, and coagulation dysfunction are witnessed in patients with critical conditions. At the outset, it was shown that the patients' signs of the disease were moderate, the complete number of leukocytes and neutrophils went up, and treatments by antiallergic and anti-inflammatory medicines were effective (5, 8).
Patients having positive RT-PCR test results and confirmed COVID-19, showed several numbers of laboratory abnormalities that were witnessed in our patient, including high CRP, white blood cell (WBC), neutrophil and lymphocyte. Moreover, lymphopenia was reported to be a weak predictive factor for SARS. These results are likely to account for the presentation of the common biomarker in viral pneumonia such as COVID-19 (9).
Given the normal status of the chest radiograph in the patients with mild or no symptoms, chest CT is potentially an instrument that contributes to the diagnosis of the infection, along with other tools such as clinical symptoms and any travel history. Lately, according to findings obtained from a series of 1014 cases, chest CT has been considered to be more sensitive for the diagnosis of 2019-nCoV infection(6).Chest CT presents a fast-paced and easy screening method for 2019-nCoV-associated presumed pneumonia. It is also now used by the National Health Committee to diagnose and treat 2019 nCoV infection (trial version fifth) (10). GGOs are the primary CT results in patients with COVID-19, as in viral pneumonia owing to other etiologies (11). Reticular and/or interlobular septal thickening, and consolidation are common associated findings. Several instances were also found of crazy-paving trends. Also, in the absence of GGO, pure consolidation is of less prevalence and these lesions are accompanied by bilateral lungs (12). Nevertheless, at the initial step of COVID-19 when the disease is diagnosed, a normal CT scan can be found in a few patients (13). Additionally, this study showed that, prior to the operation day, the chest X-ray of our patient did not present any pathologic findings and, moreover, that after the operation, her chest X-ray displayed interstitial infiltrations on both sides.
The patient in this study became afebrile 10 days after being admitted to the hospital, even without antiviral treatment. Although her chest X-ray demonstrated signs of pneumonia, there were no reports of respiratory failure. Nonetheless, how to best treat COVID-19 remains still unknown. The debate of this case has been the time and priority of elective surgery during pandemic of infection. While we did not manage to reform it, the laparoscopic cholecystectomy of the patient under examination requires specific reflection for excluding gas via the port side. Consequently, to secure patients and medical teams' safety during elective operations, it is obviously essential to develop some triage guidelines, on which the hospital performance must be based center by center. The chest radiography for the patient in this study reported mild cough lacking any evidence of pneumonia the day before the operation. In the initial stages of the clinical course of 2019-nCoV infection, these nonspecific symptoms of the mild disease cannot be easily distinguished clinically from those of various other common infectious diseases, especially during the winter when respiratory viruses are prevalent (8).
2019-nCoV can be transmitted to other people by the infected individuals even before the symptoms of the disease emerge. The epidemiological investigation of these patients has confirmed that the virus is characterized by human-to-human transmission and high levels of infectivity. It is also revealed that respiratory droplets are the major transmission route, followed by a close touch (14). The incubation period is reported to be an overall number of three to seven days, with the longest period not exceeding 14 days (15). Upon her release from the hospital and recovery in the house, the patient had transmitted the disease to her husband who was later transferred to the hospital for treatment.
The estimated fatality rate in the general population is low, almost 1-6%. Nonetheless, the patients with older age or underlying medical conditions account for most of the critical cases which are considered as the high-risk groups, thus in need of careful attention (16).
Given the high reciprocal exposure of a great number of healthcare providers with the COVID-19-infected patients in the operation rooms and therapeutic settings, the dissemination risk of such infectious diseases is extremely high, especially in asymptomatic carriers.
To conclude, the present study provides a report of a COVID-19 case in the post-operation phase, suggesting that such patients may show uncommon clinical symptoms. Therefore, upon facing a surgery candidate with unspecified viral clinical manifestations, and without any microbiological isolation, all the medical personnel should be informed and made aware so as to consider COVID-19 as a potential diagnosis, particularly in epidemic regions. Therefore, the medical personnel and healthcare providers are advised to postpone the time of surgery as well as to develop triage guidelines for selecting those patients whose operation is mandatory in all of the medical centers.
