Appendectomy in patient with suspected COVID-19 with negative COVID-19 results: A case report

Clinical Experience of Emergency Appendectomy under the COVID-19 Pandemic in a Single Institution in South Korea

Background and Objectives: The COVID-19 pandemic has brought serious changes in healthcare systems worldwide, some of which have affected patients who need emergency surgery. Acute appendicitis is the most common surgical disease requiring emergency surgery. This study was performed to determine how the COVID-19 pandemic has changed the treatment of patients with acute appendicitis in South Korea. Materials and Methods: We retrospectively reviewed a medical database that included patients who underwent surgery for acute appendicitis in our hospital from January 2019 to May 2021. We classified the patients into two groups according to whether they were treated before or after the COVID pandemic and 10 March 2020 was used as the cutoff date, which is when the World Health Organization declared the COVID pandemic. Results: A total of 444 patients were included in the “Pre-COVID-19” group and 393 patients were included in the “COVID-19” group. In the “COVID-19” group, the proportion of patients with severe morbidity was significantly lower. The time that the patients spent in the emergency room before surgery was significantly longer in the ”COVID-19” group (519.11 ± 486.57 min vs. 705.27 ± 512.59 min; p-value < 0.001). There was no difference observed in the severity of appendicitis or in the extent of surgery between the two groups. Conclusions: During the COVID-19 pandemic, a statistically significant time delay (186.16 min) was needed to confirm COVID-19 infection status. However, there was no clinical difference in the severity of appendicitis or in the extent of surgery. To ensure the safety of patients and medical staff, a COVID-19 PCR test should be performed.

Did the severity of appendicitis increase during the COVID-19 pandemic?

BACKGROUND

This study aimed to assess the severity of appendicitis during the coronavirus disease 2019 (COVID-19) pandemic, as patients with appendicitis may procrastinate seeking medical attention during the pandemic.

METHODS

Information on patients with appendicitis who were treated at the Taipei City Hospital during the COVID-19 pandemic (January 1, 2020 to June 30, 2020) was retrieved. Patients who were diagnosed with appendicitis and treated at the same hospital from January 1, 2019 to July 1, 2019 were designated as the control group. Multivariate logistic regression analysis was conducted to assess changes in the severity of appendicitis (at a 2-week interval) between the two groups.

RESULTS

We identified 307 (study group: 149; control group: 158) consecutive patients with appendicitis. The mean age was 46.2 +- 19.8 years. Between the two groups, there were no significant differences in age, sex, comorbidity, surgery type (laparoscopic or open appendectomy) or surgery time. The number of patients in the study group decreased between January 29, 2020 and April 21, 2020, which paralleled the period of spikes in the confirmed COVID-19 cases and restricted daily activities. The percentage of uncomplicated and complicated appendicitis (excluding mild appendicitis or normal appendix) in the study group increased between February 26 and March 10, as well as between April 8 and April 21. In the multivariate regression analysis, the odds of uncomplicated and complicated appendicitis increased in three bi-weeks for the study group but not in the control group.

CONCLUSION

The severity of acute appendicitis might increase during the COVID-19 pandemic, because patients with mild appendicitis (or abdominal pain) may hesitate to seek help.

Appendicitis as a presentation of COVID-19: A case report

Background

Coronavirus disease-19 (COVID-19) is an infectious respiratory disease caused by Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2). Respiratory symptoms and flu-like presentation are the most defined clinical manifestations. However, gastrointestinal symptoms with acute abdomen have been reported in a small percentage, occasionally mimicking acute appendicitis. Hence, the diagnosis of COVID-19 should be suspected and investigated in every case of acute abdomen in the present situation.

Case presentation

We report a case of a 25-year-old male who presented with features of acute appendicitis. Despite the equivocal ultrasound results, he was scheduled for an emergency appendectomy for Alvarado's score 7 out of 10, who underwent a successful appendectomy. The patient had initially tested negative on an upper respiratory COVID-19 reverse transcription-polymerase chain reaction (RT-PCR) with normal chest X-ray but few hours after the surgery patient developed a high-grade fever. An RT-PCR for COVID-19 was resent following a suspicion that came out to be positive.

Clinical discussion

Several case reports have suggested a probable association between COVID-19 and appendicitis. This case shows the limited effectiveness of clinical diagnosis for the surgical abdomen in COVID-19 patients as these two conditions share similar symptoms often needing a clinical vigilance.

Conclusion

This case reports acute appendicitis in a patient who tested positive for SARS-CoV-2 subsequently following emergency appendectomy highlighting the acute gastrointestinal presentation of COVID-19. This case exemplifies the necessity to be familiar with the gastrointestinal symptoms of COVID-19 and maintain a high level of suspicion for COVID-19 infection in cases of abdominal pain.

•

Acute appendicitis can be one of the presentation of COVID-19.

•

Clinicians need to be familiar with the gastrointestinal symptoms of COVID-19.

•

Rapid diagnosis of COVID-19 in patients with acute abdominal pain should be done to prevent the virus from spreading.

•

A negative RT-PCR for COVID-19 can't totally exclude COVID-19.

How to keep patients and staff safe from accidental SARS-CoV-2 exposure in the emergency room: Lessons from South Korea's explosive COVID-19 outbreak

Objectives:

We report our experience with an emergency room (ER) shutdown related to an accidental exposure to a patient with coronavirus disease 2019 (COVID-19) who had not been isolated.

Setting:

A 635-bed, tertiary-care hospital in Daegu, South Korea.

Methods:

To prevent nosocomial transmission of the disease, we subsequently isolated patients with suspected symptoms, relevant radiographic findings, or epidemiology. Severe acute respiratory coronavirus 2 (SARS-CoV-2) reverse-transcriptase polymerase chain reaction assays (RT-PCR) were performed for most patients requiring hospitalization. A universal mask policy and comprehensive use of personal protective equipment (PPE) were implemented. We analyzed effects of these interventions.

Results:

From the pre-shutdown period (February 10–25, 2020) to the post-shutdown period (February 28 to March 16, 2020), the mean hourly turnaround time decreased from 23:31 ±6:43 hours to 9:27 ±3:41 hours (P < .001). As a result, the proportion of the patients tested increased from 5.8% (N=1,037) to 64.6% (N=690) (P < .001) and the average number of tests per day increased from 3.8±4.3 to 24.7±5.0 (P < .001). All 23 patients with COVID-19 in the post-shutdown period were isolated in the ER without any problematic accidental exposure or nosocomial transmission. After the shutdown, several metrics increased. The median duration of stay in the ER among hospitalized patients increased from 4:30 hours (interquartile range [IQR], 2:17–9:48) to 14:33 hours (IQR, 6:55–24:50) (P < .001). Rates of intensive care unit admissions increased from 1.4% to 2.9% (P = .023), and mortality increased from 0.9% to 3.0% (P = .001).

Conclusions:

Problematic accidental exposure and nosocomial transmission of COVID-19 can be successfully prevented through active isolation and surveillance policies and comprehensive PPE use despite longer ER stays and the presence of more severely ill patients during a severe COVID-19 outbreak.
