Procalcitonin as a Prognostic Marker of Complicated Appendicitis

Introduction: Acute appendicitis is the most common cause of acute abdominal pain as well as one of the most frequently performed procedures in general surgery. Different prognostic laboratory markers have been studied to identify patients with complicated appendicitis and it is unknown whether the level of procalcitonin in adults could be used as a predictive marker. From a cut-off point, Does procalcitonin have predictive value for complicated appendicitis? Methods: Prospective, observational study. Patients from the Civil Hospital of Guadalajara with a diagnosis of Appendicitis, presurgical laboratory studies and Procalcitonin, and undergo appendectomy in this institution. A calculated sample was obtained based on the surgeries performed annually. Result(s): 80 appendicectomies were performed in the 12-month period (2021;COVID pandemic) obtaining: 37 patients with uncomplicated appendicitis (Phase I and II) 43 patients with complicated appendicitis (Phase III and IV) The procalcitonin levels of both groups were analyzed to demonstrate differences between them, Mann-Whitney U test gives us as a result a p value <0.05. For the cut-off point at the most suitable procalcitonin level for this sample we decided to use the Yauden index method in the analysis of the ROC curve: it is observed that the cut-off point with a sensitivity of 72.1% and a specificity of 81.1% for the sample is 0.305. Conclusion(s): Procalcitonin has been shown to be a useful marker for discriminating the severity of appendicitis and that the best cutoff point for this sample is 0.3 ng/dl.

Factors influencing sonographer-led bowel ultrasound service

The aim of this study was to investigate factors influencing UK sonographers' practice of adult bowel ultrasound. A mixed-method online questionnaire was designed and shared on social media platforms in April 2021. Research restrictions due to COVID19 limited the sample size permitted. Convenience sampling recruited thirty UK sonographers performing adult abdominal ultrasound in their practice. Quantitative data were analysed using descriptive statistics, and qualitative data were analysed using inductive thematic analysis. Quantitative data revealed that 53% (n= 16) of the participants expressed a lack of confidence in scanning the bowel, while 77%, (n = 23) indicated a high level of interest in training in bowel ultrasound. Although 63.3% (n = 19) of the participants reported a high level of confidence in scanning the bowel for suspected appendicitis, the majority (70%, n = 21) expressed lack of confidence in examining the bowel for other pathologies like inflammatory bowel disease (IBD). Inductive thematic analysis of qualitative data revealed that the participants had varying opinions on this topic. Emerging themes included training opportunities, preference of other imaging modalities, management challenges, sonographers, and radiologists' influence. Qualitative results suggested that factors influencing sonographer evaluation of the bowel include advanced levels of training, a high degree of support from radiologists, regular bowel ultrasound lists, audits, and feedback from clinicians. Based on the findings of this study, most sonographers are not confident in practising bowel ultrasound beyond the evaluation of suspected appendicitis. Surveyed sonographers were interested in expanding their roles into other areas of bowel ultrasound like examining for Crohn's and ulcerative colitis. Sonographer role extension into this area of practice is limited by various factors like chronic shortage of sonographers, increasing workload, limited training, and the perception of diminishing support from radiologists. We recommend a future study that is not limited by a small sample size.

Impact of the Coronavirus (COVID-19) Pandemic on the Care of Pediatric Acute Appendicitis.

BACKGROUND: Appendicitis is the most common abdominal surgical emergency in children. With the rise of the Coronavirus-19 pandemic, quarantine measures have been enforced to limit the viral transmission of this disease. The purpose of this study was to identify differences in the clinical presentation and outcomes of pediatric acute appendicitis during the Coronavirus-19 pandemic. METHODS: A single-institution retrospective assessment of all pediatric patients (<18 years old) with acute appendicitis from December 2019 to June 2020 was performed at a tertiary care children's hospital. Patients were divided into two groups: (1) the Pre-COVID group presented on or before March 15, 2020, and (2) the COVID group presented after March 15, 2020. Demographic, preoperative, and clinical outcomes data were analyzed. RESULTS: 45 patients were included with a median age of 13 years [IQR 9.9 - 16.2] and 35 males (78%). 28 patients were in the Pre-COVID group (62%) and 17 in the COVID group (38%). There were no differences in demographics or use of diagnostic imaging. The COVID group did have a significantly delayed presentation from symptom onset (36 vs 24 hours, P < .05), higher Pediatric Appendicitis Scores (8 vs 6, P = .003), and longer hospital stays (2.2 vs 1.3 days, P = .04). There were no significant differences for rates of re-admission, re-operation, surgical site infection, perforation, or abscess formation. CONCLUSION: During the Coronavirus-19 pandemic, the incidence of pediatric acute appendicitis was approximately 40% lower. These children presented in a delayed fashion with longer hospital stays. No differences were noted for postoperative complications.

Epidemiology and Outcome of Acute Appendicitis during and before the COVID-19 Pandemic: A Retrospective Single-Center Analysis.

Background and Objectives: We investigated epidemiological factors and outcomes, including the development of complications, for patients with appendicitis according to three sequential coronavirus disease 2019 (COVID-19) pandemic periods, divided by specific time points. Materials and Methods: This observational study included patients with acute appendicitis who arrived at a single-center between March 2019 and April 2022. The study divided the pandemic into three periods: period A as the first phase of the pandemic (from 1 March 2020 to 22 August 2021), period B as the time period the medical system stabilized (from 23 August 2021 to 31 December 2021), and period C as the time period of the exploration of patients with COVID-19 in South Korea (from 1 January 2022 to 30 April 2022). Data collection was based on medical records. The primary outcome was presence or absence of complications and the secondary outcomes were the time taken from ED visit to surgical intervention, the presence and time of the first administration of antibiotics, and the hospital stay time. Results: Of 1,101 patients, 1,039 were included, with 326 and 711 patients before and during the pandemic, respectively. Incidence of complications was not affected during the pandemic (before the pandemic 58.0%; period A 62.7%; period B,55.4%; and period C 58.1%; p = 0.358). Time from symptom onset to emergency department (ED) arrival significantly decreased during the pandemic (before the pandemic 47.8 ± 84.3 h; pandemic 35.0 ± 54 h; p = 0.003). Time from ED visit to the operating room was statistically significantly increased during the pandemic (before the pandemic 14.3 ± 21.67 h; period A 18.8 ± 14.02 h; period B 18.8 ± 8.57 h; period C 18.3 ± 12.95 h; p = 0.001). Age and time from symptom onset to ED arrival were variables affecting the incidence of complications; however, they were not affected during the pandemic (age, OR 2.382; 95% CI 1.545-3.670; time from symptom onset to ED arrival, OR 1.010, 95% CI 1.006-1.010; p < 0.001). Conclusions: This study found no differences in postoperative complications or treatment durations between pandemic periods. The incidence of appendicitis complications was significantly influenced by age and the duration between the onset of symptoms and arrival at the emergency department, but not by the pandemic period itself.

Patients with appendicitis during COVID-19 pandemic: a retrospective cohort study.

The Coronavirus Disease 19 (COVID-19) pandemic greatly affected the Quebec healthcare system from spring 2020 onward; the consultation delays that were generated may have delayed the management of urgent intra-abdominal pathologies. Our objective was to evaluate the impact of the pandemic on the length of stay and complications within 30 days of treatment of patients consulting for acute appendicitis (AA) at the Centres intégrés universitaires de santé et de services sociaux (CIUSSS) de l'Estrie-Centre hospitalier universitaire de Sherbrooke (Estrie-CHUS), Quebec, Canada. Methods: The authors conducted a single-center retrospective cohort study on the charts of all patients diagnosed with AA at the CIUSSS de l'Estrie-CHUS between March 13 and June 22, 2019 (control group) and between March 13 and June 22, 2020 (pandemic group). This corresponds to the first wave of COVID-19 in Quebec. Patients included were those with a radiologically confirmed diagnosis of AA. There was no exclusion criteria. Outcomes assessed were length of hospital stay and 30-day complications. Results: The authors analyzed the charts of 209 patients with AA (117 patients in the control group and 92 patients in the pandemic group). No statistically significant difference was observed for the length of stay or the complications between the groups. The only significant difference was the presence of hemodynamic instability on admission (22.2 vs. 41.3%, P=0.004) as well as a trend that did not reach statistical significance regarding the proportions of reoperation before 30 days (0.9 vs. 5.4%, P=0.060). Conclusion: In conclusion, the pandemic did not affect the length of stay of AA managed at the CIUSSS de l'Estrie-CHUS. It is not possible to conclude whether the first wave of the pandemic influenced complications related to AA.

Typical and Atypical Presentations of Appendicitis and Their Implications for Diagnosis and Treatment: A Literature Review.

Appendicitis, an acute inflammation of the appendix, affects all demographic groups and exhibits various incidences and clinical manifestations. While acute appendicitis typically presents with colicky periumbilical abdominal pain that localizes to the right lower quadrant, atypical presentations are more common in children, geriatric, and pregnant patient populations, leading to delays in diagnosis. Clinical evaluation, clinical scoring systems, and inflammatory markers are commonly used, but their limitations have led to the increased use of diagnostic imaging in patients suspected of appendicitis. Acute appendicitis is managed by non-operative and operative management, depending on whether it is uncomplicated or complicated. Developing diagnostic pathways to improve outcomes and reduce complications is crucial. Although medical advancements have been made, diagnosing and managing appendicitis can be challenging, mainly when patients are present atypically. This literature review aims to comprehensively review typical and atypical presentations of appendicitis and their current implications for diagnosis and treatment modalities in pediatric, adult, pregnant, and geriatric patient populations.

[Detection of SARS-CoV-2 RNA in the mucosa of the appendices of children with COVID-19]. / Vyyavlenie RNK SARS-CoV-2 v slizistoi obolochke cherveobraznogo otrostka u detei s COVID-19.

Background. The novel coronavirus infection (COVID-19) often manifests in children as diarrhea, vomiting, abdominal pain, and some children develop acute appendicitis. To elucidate the role of SARS-CoV-2 in the development of acute appendicitis, a more detailed study of the presence of its genetic material in the tissue of the appendix. OBJECTIVE: Determination of SARS-CoV-2 RNA in appendices of children with COVID-19 by fluorescence in situ hybridization (FISH). MATERIAL AND METHODS: A retrospective analysis of case histories and morphological analysis using FISH of appendices of pediatric patients with established clinical diagnosis of acute appendicitis and confirmed infection with SARS-CoV-2 was performed. The material was divided into 3 groups: 1st -appendices obtained during appendectomy in children with established clinical diagnosis of «coronavirus infection¼ (COVID-19, PCR+) (n=42; mean age 10.8 years); 2nd - appendices of children (n=55; mean age 9.7 years) with acute appendicitis obtained before the onset of the COVID-19 pandemic; 3rd (control) group (n=38; mean age 10.3 years) - autopsy material of the appendices (intact). RESULTS: In all samples of the appendices of the 1st group, a positive SARS-CoV-2 viral RNA signal was noted in the cytoplasm of most epithelial cells and single immunocompetent cells. The signal intensity remained the same in all slides, regardless of age. In all samples obtained from patients without COVID-19 (groups 2 and 3), confocal microscopy did not reveal a signal, which indicates successful adaptation of the FISH method in this study and excludes the false positive results. CONCLUSION: In the epithelium of the appendices of children of different age with COVID-19, the FISH method revealed SARS-CoV-2 RNA, which does not exclude the association between viral invasion and the development of acute appendicitis.

Higher Rates of Complicated Appendicitis During the COVID-19 Pandemic: A Year-to-Year Analysis.

INTRODUCTION: The COVID-19 pandemic impacted presentation, management strategies, and patient outcomes of numerous medical conditions. The aim of this study is to perform a year-to-year comparison of clinical outcomes of patients with acute appendicitis (AA) before and during the pandemic. METHODS: Patients treated for AA during the initial 12-mo period of the pandemic at our institute were compared to those treated for AA during the 12-mo period before. Clinical and laboratory parameters, treatment strategies, intraoperative findings, pathology reports, and postoperative outcomes were compared. RESULTS: During the study period, 541 patients presented with AA. The median (interquartile range) age was 28 (21-40) y and 292 (54%) were males. 262 (48%) patients presented during the pre-COVID-19 period, while 279 patients (52%) presented during the COVID 19 pandemic. The groups were comparable for baseline clinical data and imaging results upon index admission. There was no significant difference in rate of nonoperative treatment between the Pre-COVID-19 and During-COVID-19 eras (51% versus 53%, P = 0.6) as well as the success rate of such treatment (95.4% versus 96.4%, P = 0.3). Significantly more patients presented with a periappendicular abscess during COVID-19 (4.6% versus 1.1%, P = 0.01) and median (interquartile range) operative time was significantly longer (78 (61-90) versus 32.5 (27-45) min, P < 0.001). Pathology reports revealed a higher rate of perforated appendicitis during COVID-19 (27.4% versus 10.2%, P < 0.001). CONCLUSIONS: Patients with AA present with higher rates of perforated and complicated appendicitis during the COVID-19 pandemic. The success rates of nonoperative management in selected patients with noncomplicated AA did not change during the pandemic and is a safe, feasible, option.

Racism in pediatric health

SPECIAL REPORT Since the inception of the United States, social, economic, political, and scientific institutions have been built on a foundation emphasizing the inferiority of individuals related to phenotypic differences.1 This hierarchy ensconced white individuals as superior to all other groups with Native Americans and Blacks on the bottom. Some fifty years after the discovery of the genetic code, at a White House ceremony in 2000 to announce the discovery, Craig Venter, a pioneer of DNA sequencing, observed, "The concept of race has no genetic or scientific basis. With structural or institutional racism, there is decreased access to health care and resources for education, leading to lower health literacy and fewer health care providers of color.12'13 Over time, this has led to a distrust of the health care system as a whole by POC due to widely publicized historical events such as the Tuskegee Syphilis Study and the Marion tuberculosis outbreak. [...]non-Hispanic Blacks have a higher prevalence of recurrent asthma exacerbations and hospitalizations than Whites after adjusting for demographic and socioeconomic factors.16 One study revealed that with non-Black children, poor children were 45% more likely than children who were not poor to have asthma.

To evaluate the diagnostic accuracy of Modified Alvarado and Tzanakis scores in diagnosing Acute Appendicitis

Background: Evaluation of the diagnostic accuracy of Modified Alvarado and Tzanakis scores in diagnosing Acute Appendicitis. Materials & methods: Due to COVID-19 pandemic the sample size was selected to be 51. CECT abdomen was done. Postoperatively, the Modified Alvarado and Tzanakis scoring systems were applied on all these patients using scoring sheets keeping a cut off of 7 for the Modified Alvarado score, and 8 for the Tzanakis score followed by which, histopathological diagnosis of the removed appendix was obtained. Subsequently, comparison was made between the histopathological findings and the above calculated scores. Data were analysed using SPSS version 23. Qualitative data was compared using Chi-square test or Fischer exact test as applicable. Results: The reported sensitivity and specificity for modified Alvarado score was 97.6% and 66.7% respectively while for Tzanakis scoring was reported as 92.9% and 100% respectively. Positive predictive value for modified Alvarado score was 93.2 with a negative predictive value of 85.6% and a diagnostic accuracy of 92.1%. Positive predictive value for Tzanakis score was 100% with a negative predictive value of 75.1% and a diagnostic accuracy of 94.2%. Conclusion: Tzanakis scoring system is an effective modality to establish the accurate diagnosis of acute appendicitis which requires surgery especially in low resource areas and helps in reducing the rates of negative appendicectomy. Though acute appendicitis is a clinical diagnosis the scoring system can complement the clinical diagnosis.

EFFECT OF THE COVID-19 PANDEMIC ON THE CLINICAL EVOLUTION OF ACUTE APPENDICITIS AND ACUTE CHOLECYSTITIS: A URUGUAYAN EXPERIENCE

Background: The World Health Organization declared a worldwide Coronavirus (COVID-19) pandemic on March 11, 2020. In Uruguay, unlike most countries, a mandatory confinement was not declared. On the contrary, an extensive education and prevention campaign was carried out associated with measures to reduce social mobility, such as prohibiting meetings and closing bars.Objectives: The aim of the present study was to evaluate the COVID-19 pandemic in Uruguay and its repercussion on the clinical evolution of the two most common surgical pathologies: acute appendicitis (AA) and acute cholecystitis (AC).Methods: A retrospective comparative cohort study was performed at the Emergency Department of the University Hospital "Hospital de Clinicas Manuel Quintela,” the most important tertiary referral hospital in the city of Montevideo, capital of Uruguay. Two cohorts were identified: 13th of March 2019 to 13th of June 2019 [Pre-Covid period (PCP)] and the same period in 2020 [Pandemic Covid period (PCVP)]. Demographic and clinical data were analyzed.Results: A total of 118 cases were registered in 2019 and 109 in 2020. There were 43 cases (36.4%) of acute appendicitis in the pre-Covid period and 42 cases (36.5%) in Pandemic Covid period (p = 0.745). Acute cholecystitis cases differed significantly between cohorts, with a raise of cases in the Pandemic Covid period (14 vs 25) (p = 0.027). The surgical approach (Laparoscopy vs Open) did not change significantly (p = 0.207). A significant increase in complicated cases (AA + AC) was found during the pandemic (PCP 57 cases vs PCVP 67 cases) (p < 0.001). The sub-analysis of AA and AC showed a significant increase in AA's complicated cases during PCVP (14 vs 25;p < 0.001) and no significant changes in the AC group (p = 0.99).Conclusion: An increase of complicated cases of AA was observed with maintenance of the number of consultations that might be explained by the excellent pre-hospital care system and absence of lock-down measures. The results are contradictory in some aspects, which calls for a deeper analysis, comparing different realities and longer periods of time in order to be able to draw conclusions that are representative for the Coronavirus pandemic in Uruguay.

Clinical and morphological symptoms of gangrenous appendicitis in children with laboratory-confirmed novel coronavirus infection

Over recent years, amid the novel coronavirus disease (COVID-19) pandemic the prevalence of appendicitis in children has increased. However, its morphological characteristics are not described completely. The article elucidates clinical and morphological features of gangrenous appendicitis in hospitalized children with laboratory-confirmed COVID-19 diagnosis. The authors present the clinical, laboratory, instrumental and morphological findings in schoolchildren with gangrenous appendicitis associated with SARS-CoV-2, confirmed by nasopharyngeal swab PCR-testing. The disease was characterized by an acute onset, rapid development of abdominal pain syndrome and typical inflammatory changes in the clinical blood analysis: moderate leukocytosis (15.6×109/l), pronounced neutrophilia (82.2%), and thrombocytopenia (103 to 144×109/l). All patients had echographic signs of inflammatory transformation of the appendix which was removed on the first day of hospitalization (the first day of the disease) by laparoscopic technique. The examination of the removed biomaterial revealed a tendency to thrombosis in the small vessels of the process and ulcerative changes accompanied by necrosis. There is a discussion of the relationship between the development of gangrenous appendicitis and the clinical course of COVID-19 infection. It is necessary to continue investigations, perform in-depth analysis of the factors causing pathological changes, and to clarify the role of SARS-CoV-2 disease with the aim of preventing the spread of COVID-19. © 2023, Meditsina-Inform LLC.

Management of Acute Appendicitis During the COVID-19 Pandemic: A Single-Centre Retrospective Cohort Study.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, the management of acute appendicitis shifted towards non-operative management in the United Kingdom (UK). The open approach was recommended over the laparoscopic approach due to the risk of aerosol generation and subsequent contamination. The aim of this study was to compare the overall management and surgical outcomes of the patients treated for acute appendicitis before and during the COVID-19 pandemic. MATERIALS AND METHODS: We performed a retrospective cohort study at a single district general hospital in the UK. We compared the management and outcome of the patients diagnosed with acute appendicitis before the pandemic, from March to August 2019, and during the pandemic, from March to August 2020. We looked at the patient demographics, methods of diagnosis, management, and surgical outcomes for these patients. The primary outcome of the study was the 30-day readmission rate. Secondary outcomes included length of stay and post-operative complications. RESULTS: Over the period of six months, a total of 179 patients were diagnosed with acute appendicitis in 2019 (Pre-COVID-19 pandemic, from March 1, 2019, to August 31, 2019) versus 152 in 2020 (during the COVID-19 pandemic, from March 1, 2020, to August 31, 2020). For the 2019 cohort, the mean age of the patients was 33 (range 6-86 years), 52% (n=93) were female, and the mean BMI was 26 (range 14-58). For the 2020 cohort, the mean age was 37 (range 4-93 years), 48% (n=73) of the patients were female, and the mean BMI was 27 (range 16-53). At the first presentation, in 2019, 97.2% of the patients (174 out of 179) received surgical treatment compared to 70.4% (107 out of 152) in 2020. Three per cent of the patients (n=5) were managed conservatively in 2019 (two out these failed conservative management) as compared to 29.6% (n=45) in 2020 (21 of these failed conservative management). Pre-pandemic, only 32.4% (n= 57, ultrasound (US) scan: 11, computer tomography (CT) scan): 45, both US and CT: 1) of the patients received imaging to confirm the diagnosis as compared to 53.3% during pandemic (n=81, US scan: 12, CT scan: 63, both US and CT: 6). Overall, the CT to US ratio increased. We found that during 2019, 91.5% (n=161/176) of the patients who received surgical treatment went through laparoscopic surgery as compared to only 74.2% (n=95/128) in 2020 (p<0.0001). Postoperative complications occurred in 5.1% (n=9/176) of the surgical patients in 2019 as compared to 12.5% (n=16/128) in 2020 (p<0.033). The mean length of hospital stay in 2019 was 2.9 days (range 1-11) versus 4.5 days in 2020 (range 1-57) (p<0.0001). The 30-day readmission rate was 4.5% (8/179) versus 19.1% (29/152) (p<0.0001). The 90-day mortality rate was zero for both cohorts. CONCLUSION: Our study shows that the management of acute appendicitis changed due to the COVID-19 pandemic. More patients went through imaging, especially CT scans for diagnosis and received non-operative management with antibiotics only. The open surgical approach became more common during the pandemic. This was associated with longer lengths of hospital stay, more readmissions, and an increase in postoperative complications.

Diagnosing the acute abdomen during a global contrast shortage: a single centre experience.

BACKGROUND: The COVID-19 pandemic led to a global shortage of iodinated contrast media (ICM) in early 2022. ICM is used in more than half of the computed tomography of the abdomen and pelvis (CTAP) performed to diagnose an acute abdomen (AA). In response to the shortage, the RANZCR published contrast-conserving recommendations. This study aimed to compare AA diagnostic outcomes of non-contrast CTs performed before and during the shortage. METHODS: A single-centre retrospective observational cohort study of all adult patients presenting with an AA who underwent a CTAP was conducted during the contrast shortage period from May to July 2022. The pre-shortage control comparison group was from January to March 2022; key demographics, imaging modality indication and diagnostic outcomes were collected and analysed using SPSS v27. RESULTS: Nine hundred and sixty-two cases met the inclusion criteria, of which n = 502, 52.2% were in the shortage period group. There was a significant increase of 464% in the number of non-contrast CTAPs performed during the shortage period (P < 0.001). For the six AA pathologies, only n = 3, 1.8% of non-contrast CTAPs had equivocal findings requiring further imaging with a contrast CTAP. Of the total CTs performed, n = 464, 48.2% were negative. CONCLUSION: This study showed that when non-contrast CTs are selected appropriately, they appear to be non-inferior to contrast-enhanced CTAPs in diagnosing acute appendicitis, colitis, diverticulitis, hernia, collection, and obstruction. This study highlights the need for further research into utilizing non-contrast scans for assessing the AA to minimize contrast-associated complications.

Impact of the COVID-19 pandemic on the outcomes of laparoscopic appendectomy for acute appendicitis.

Purpose: This retrospective study aimed to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on the time interval from symptom onset to surgery and on the operative outcomes of laparoscopic appendectomy for patients with acute appendicitis. Methods: Between October 2018 and July 2021, laparoscopic appendectomy was performed in 502 patients with acute appendicitis admitted to Hallym University Chuncheon Sacred Heart Hospital in Chuncheon, Korea. We compared demographic data, serum levels of inflammatory markers, time to event of appendicitis, and operative outcomes between the pre-COVID-19 and post-COVID-19 pandemic groups. Results: Laparoscopic appendectomy was performed in 271 patients in the pre-COVID-19 group and in 231 patients in the post-COVID-19 group. There were no differences in baseline characteristics, serum inflammatory marker levels, or the proportions of complicated appendicitis between the groups (25.1%, pre-COVID-19 vs. 31.6%, post-COVID-19; P = 0.106). The time intervals between symptom onset and hospital arrival (24.42 hours vs. 23.59 hours, P = 0.743) and between hospital arrival and the start of surgery (10.12 hours vs. 9.04 hours, P = 0.246) did not increase post-COVID-19. The overall 30-day postoperative complication rate did not differ significantly between the groups (9.6% vs. 10.8%, P = 0.650), and the severity of 30-day postoperative complications was also similar in both groups (P = 0.447). Conclusion: This study demonstrates that hospitalization and surgeries were not delayed in patients with acute appendicitis and that the operative outcomes of laparoscopic appendectomy did not worsen despite the COVID-19 pandemic.

Incidence of Pediatric Perforated Appendicitis during the COVID-19 Pandemic; a Systematic Review and Meta-Analysis.

INTRODUCTION: COVID-19 has affected the pattern of referral to medical centers and quarantine against COVID-19 might delay referral and management of surgical emergencies. This study aimed to compare the pooled event rate of pediatric perforated appendicitis before and during the COVID-19 pandemic. METHODS: This was a systematic review and meta-analysis study based on the PRISMA guidelines. Scopus, Web of Sciences, and PubMed databases were searched for studies reporting the rate of perforated appendicitis based on the post-appendectomy observations or imaging methods. The Egger bias test and funnel plot were used to detect and depict publication bias. Statistical analysis was performed in Comprehensive Meta-analysis package version 3. RESULTS: Twelve studies were eligible for inclusion in our study. The pooled prevalence of pediatric perforated appendicitis in the pre-COVID era was 28.5% (CI95%: 28.3 to 28.7%) with a heterogeneity of 99%. In the COVID era, the event rate proportion was 39.4% (CI95%: 36.6 to 42.3%) with a heterogeneity of 99%. There was a significant difference in the subgroup analysis within the pre-COVID and COVID era (P<0.001), showing a higher perforation rate in the COVID era. CONCLUSION: Our study showed that during the COVID-19 pandemic, the rate of perforated appendicitis has significantly increased in comparison to before the COVID-19 pandemic.

Diary of a Family Physician

My first patient is a 13-year-old boy with abdominal pain. He had a fever of 102.6°F (39.0°C) last night and is in significant distress this morning. He has no appetite and has not vomited. He has not had a bowel movement for three days. On examination, he has right lower quadrant tenderness but no rebound. I direct him to the ED with concern for appendicitis.

Appendicular peritonitis as a variant of Crohn's disease manifestation in children recovered from a novel coronavirus infection COVID-19.

Immune changes arising against the background of COVID-19 can lead to the manifestation of autoimmune diseases and provoke the development of Crohn's disease. In the presented work, we describe two clinical cases of manifestation of Crohn's disease in children after suffering a novel coronavirus infection COVID-19. Moreover, the variant of manifestation in both cases was spilled purulent appendicular peritonitis. In the first case, the child underwent a traditional appendectomy and abdominal sanitation. However, the choice of traditional appendectomy in this version of the pathological process led to severe consequences for the patient (a complicated postoperative period and multiple surgical interventions), including for the formed intraperitoneal abscesses and intestinal fistula, which is most characteristic of Crohn's disease. Therefore, the patient was diagnosed with Crohn's disease only after numerous operations. Regarding the second case, the situation was completely different, despite the obvious manifestations of ARVI (sore throat, fever), which led to the belated diagnosis of appendicitis in this child. Laparoscopic appendectomy and simultaneous adequate abdominal sanitation made it possible to avoid repeated surgical interventions in this case. In both cases, patients at the diagnosis were sent to federal clinics to select specific therapy. In our opinion, it is worth paying close attention to pediatric patients with a novel coronavirus infection and abdominal pain syndrome since this may be onset of inflammatory bowel disease.Copyright © 2022, Dynasty Publishing House.

Acute appendicitis

Acute appendicitis is inflammation of the vermiform appendix. It is the commonest general surgical emergency in children and young adults, yet its diagnosis can still confound even the most skilled surgeon due to its highly variable presentation of appendicitis, with fewer than 50% of patients exhibiting classical features. Taking a detailed history and performing a careful examination remains the cornerstone of diagnosis. Urinalysis and blood tests, particularly C-reactive protein, are useful adjuncts and are performed routinely. Radiological imaging, commonly ultrasound and computed tomography scans, also have a role when the diagnosis is unclear and/or other common conditions need to be excluded, such as gynaecological pathology in young females. Nevertheless 20% of appendices removed in UK are histologically normal. Appendicitis scoring systems may further assist in stratifying risk and increasing the accuracy of diagnosis. Recently, there has been growing interest in non-surgical management of appendicitis, particularly during the COVID-19 pandemic. Antibiotics alone have been used to successfully treat uncomplicated appendicitis (without perforation, abscess or gangrene) in the short-term, however nearly 40% of these cases eventually require appendicectomy. Surgery, usually laparoscopic appendicectomy, remains the treatment of choice for acute appendicitis and non-operative management is reserved for specific cases.Copyright © 2023

Management of appendicitis: appendicectomy, antibiotic therapy, or both?

Appendicitis is a global disease with an incidence of 7-12% in the population of the USA and Europe but is low and rising in the developing world. It is the most common acute general surgical emergency, but as no investigation is accurate, the diagnosis has to rely on clinical symptoms and signs and, thus, frequently misdiagnosed. The aim of the study was to debate the arguments for managing appendicitis (operative, nonoperative, or both). Patients and methods: Electronic searches of the MEDLINE (PubMed) database, Cochrane Library, and Science Citation Index were performed to identify original published studies on appendicitis and the pre-COVID-19 (coronavirus disease 2019) and post-COVID-19 management. Relevant articles were searched from relevant chapters in specialized texts, and all have been included. Discussion: There are indications for operative (surgery), nonoperative (antibiotics), or both in the management of acute appendicitis. Although laparoscopic appendicectomy is becoming the gold standard of treatment, knowledge of the pros and cons of this approach versus the open approach is important. The controversy in the management of the appendix mass/abscess between an expedient appendicectomy or a combination of conservative management (antibiotics) and interval appendicectomy remains. Conclusion: Laparoscopic appendicectomy is becoming the gold standard for the treatment of appendicitis. However, the advantages of the innovations in minimally invasive and endoscopic surgery are unlikely to render formal open appendicectomy obsolete. Nonoperative management with antibiotics may suffice in selected cases with uncomplicated appendicitis. It is imperative that patients are counseled appropriately if primary antibiotic treatment is to be routinely offered as first-line therapy.
