Ha SC, Tsai YH, Koh CC, Hong SG, Chen Y, Yao CL. Blood biomarkers to distinguish complicated and uncomplicated appendicitis in pediatric patients. J Formos Med Assoc 2024:S0929-6646(24)00056-1. [PMID: 38336508 DOI: 10.1016/j.jfma.2024.01.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 01/07/2024] [Accepted: 01/20/2024] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND /Purpose: Acute appendicitis (AA) stands as the most prevalent cause of acute abdominal pain among children. The potential for morbidity escalates significantly when uncomplicated appendicitis (UA) progresses to complicated appendicitis (CA), which can encompass gangrenous, necrotic, or perforated appendicitis. Consequently, establishing an early and accurate diagnosis of AA, and effectively differentiating CA from UA, becomes paramount. This study explores the diagnostic utility of various blood biomarkers for distinguishing CA from UA in pediatric patients. METHODS We conducted a retrospective review of medical records pertaining to pediatric patients who underwent surgery for AA. Patients were categorized as either having UA or CA based on histopathological examination of the appendix. The data collected and analyzed included demographic information, white blood cell (WBC) count, neutrophil proportion, lymphocyte proportion, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP) levels upon admission. RESULTS Among the 192 pediatric patients who underwent surgery for AA, 150 were diagnosed with UA, while 42 were diagnosed with CA. The CA group exhibited significantly higher neutrophil proportions, NLRs, PLRs, and CRP levels, alongside lower lymphocyte proportions (all p < 0.01) compared to the UA group. Receiver operating characteristic (ROC) curve analysis disclosed that CRP exhibited the highest specificity, sensitivity, and positive and negative predictive values for predicting CA. CONCLUSION CRP emerges as a valuable biomarker for differentiating complicated appendicitis from uncomplicated appendicitis.

Tryptase in Acute Appendicitis: Unveiling Allergic Connections through Compelling Evidence. Int J Mol Sci 2024; 25:1645. [PMID: 38338923 PMCID: PMC10855922 DOI: 10.3390/ijms25031645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 01/23/2024] [Accepted: 01/24/2024] [Indexed: 02/12/2024] Open
Abstract
The aetiology of acute appendicitis (AA), the most frequent abdominal surgical emergency, is still unclarified. Recent epidemiologic, clinical and laboratorial data point to an allergic component in the pathophysiology of AA. Mastocytes participate in the Th2 immune response, releasing inflammatory mediators from their granules upon stimulation by IgE-specific antigens. Among the well-known mediators are histamine, serotonin and tryptase, which are responsible for the clinical manifestations of allergies. We conducted a prospective single-centre study to measure histamine and serotonin (commercial ELISA kit) and tryptase (ImmunoCAP System) concentrations in appendicular lavage fluid (ALF) and serum. Consecutive patients presenting to the emergency department with a clinical diagnosis of AA were enrolled: 22 patients with phlegmonous AA and 24 with gangrenous AA The control group was composed of 14 patients referred for colectomy for colon malignancy. Appendectomy was performed during colectomy. Tryptase levels were strikingly different between histological groups, both in ALF and serum (p < 0.001); ALF levels were higher than serum levels. Tryptase concentrations in ALF were 109 times higher in phlegmonous AA (APA) (796.8 (194.1-980.5) pg/mL) and 114 times higher in gangrenous AA (AGA) (837.4 (272.6-1075.1) pg/mL) than in the control group (7.3 (4.5-10.3) pg/mL. For the diagnosis of AA, the discriminative power of serum tryptase concentration was good (AUC = 0.825), but discriminative power was weak (AUC = 0.559) for the differential diagnosis between APA and AGA. Mastocytes are involved in AA during clinical presentations of both phlegmonous and gangrenous appendicitis, and no significant differences in concentration were found. No differences were found in serum and ALF concentrations of histamine and serotonin between histological groups. Due to their short half-lives, these might have elapsed by the time the samples were collected. In future research, these determinations should be made immediately after appendectomy. Our findings confirm the hypersensitivity type I reaction as an event occurring in the pathogenesis of AA: tryptase levels in ALF and serum were higher among patients with AA when compared to the control group, which is in line with a Th2 immune response and supports the concept of the presence of an allergic reaction in the pathogenesis of acute appendicitis. Our results, if confirmed, may have clinical implications for the treatment of AA.

Ann Med 2023; 55:2248454. [PMID: 37862106 PMCID: PMC10763853 DOI: 10.1080/07853890.2023.2248454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Accepted: 08/11/2023] [Indexed: 10/22/2023] Open
Abstract
BACKGROUND Glycaemic dysregulation potentiates the pro-inflammatory response and increases oxidative injury; therefore, preoperative hyperglycaemia is linked to increased mortalities. In addition, inflammation is accompanied by higher glycated haemoglobin (HbA1c) levels, and the relationship between this and random blood sugar (RBS) could be non-linear. METHODS This is a cross-sectional study. Non-diabetic paediatric patients with acute surgical abdomen, presenting to the emergency surgical services were enrolled, over a period of 6 months. They were all screened for their random blood sugar and HbA1c levels. RESULTS Fifty-three cases were studied. The prevalence of glycaemic dysregulation in the enrolled children was high. Abnormal HbA1c was observed in 66% of the study group. Stress hyperglycaemia was observed in 60% of the enrolled children. There was a significant correlation (r = 0.770, p-value: < 0.001) between RBS and the total leucocytic count (TLC). The TLC cutoff value for predicting stress hyperglycaemia was 13,595 cells/mm3. The cutoff value of RBS for predicting leukocytosis was 111.5 mg/dl. Median RBS level was significantly higher in complicated appendicitis (169.5 mg/dl), compared to uncomplicated appendicitis (118.0 mg/dl). CONCLUSION HbA1c and RBS could be used as inflammatory markers for surgical acute abdomen and its degree of severity, respectively. HbA1c rises in a considerable number of cases with surgical acute abdomen, irrespective of the disease stage. However, as the disease progresses, the random blood sugar rises due to stress hyperglycaemia, thus becoming a surrogate inflammatory marker.

Abstract
BACKGROUND Primary infection has been questioned as the pathogenetic cause of acute appendicitis. We attempted to identify the bacteria involved and to investigate if their species, types, or combinations affected the severity of acute appendicitis in children. METHODS Samples from both the appendiceal lumen and the peritoneal cavity of 72 children who underwent appendectomy were collected to perform bacterial culture analysis. The outcomes were studied to identify if and how they were associated with the severity of the disease. Regression analysis was performed to identify any risk factors associated with complicated appendicitis. RESULTS Escherichia coli, Pseudomonas aeruginosa, and Streptococcus species were the most common pathogens found in the study population. The same microorganisms, either combined or separate, were the most common in the appendiceal lumen and the peritoneal cavity of patients with complicated appendicitis. Gram-negative bacteria and polymicrobial cultures in the peritoneal fluid and in the appendiceal lumen were associated with complicated appendicitis. Polymicrobial cultures in the peritoneal cavity presented a four times higher risk of complicated appendicitis. CONCLUSIONS Polymicrobial presentation and Gram-negative bacteria are associated with complicated appendicitis. Antibiotic regimens should target the combinations of the most frequently identified pathogens, speculating the value of early antipseudomonal intervention.

Int J Mol Sci 2023; 24:ijms24109091. [PMID: 37240441 DOI: 10.3390/ijms24109091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Revised: 05/11/2023] [Accepted: 05/13/2023] [Indexed: 05/28/2023] Open
Abstract
Several pieces of evidence point to an allergic component as a trigger of acute appendicitis. As the Th2 immune response is characterized by eosinophil mobilization to the target organ and release of their cationic granule proteins, it is reasonable to investigate if the degranulation of eosinophils could be associated with the local injury. The primary aim of this study is to evaluate the participation of eosinophils granules proteins in acute appendicitis, both at local and systemic levels and the secondary aim is to evaluate the diagnostic accuracy of eosinophils granules proteins for the detection of acute appendicitis, as well as for distinguishing between complicated and uncomplicated acute appendicitis. Eosinophil-derived neurotoxin (EDN), eosinophil cationic protein (ECP) and eosinophil peroxidase (EP) are the most well-known eosinophil granule proteins. From August 2021 to April 2022, we present a prospective single-center study to evaluate the EDN, ECP, and EP concentrations simultaneously in appendicular lavage fluid (ALF) and the serum of 22 patients with acute phlegmonous appendicitis (APA), 24 with acute gangrenous appendicitis (AGA), and 14 normal controls. Concerning EDN, no differences were found between groups. ECP concentrations in ALF and serum were significantly higher in the histologically confirmed acute appendicitis compared to the control groups (p < 0.0001 and p < 0.0001, respectively). In ALF, no differences were found between ECP levels in APA: 38.85 ng/mL (IQR 26.50-51.77) and AGA 51.55 ng/mL (IQR 39.55-70.09) groups (p = 0.176). In the serum, no difference was found between ECP levels at APA: 39 ng/mL (IQR 21.30-56.90) and AGA: 51.30 ng/mL (IQR 20.25-62.59) (p = 0.100). For EP, the concentrations in ALF (p < 0.001) and serum (p < 0.001) were both higher in acute appendicitis compared to the control. In ALF, no difference was found between APA: 240.28 ng/mL (IQR 191.2-341.3) and AGA: 302.5 (IQR 227.7-535.85) (p = 0.236). In the serum, no differences were found between APA: 158.4 ng/mL (IQR 111.09-222.1) and AGA: 235.27 (IQR 192.33-262.51) (p = 0.179). Globally, the ALF concentrations were higher than serum concentrations, reflecting an intense inflammatory local reaction in AA. The optimal ECP cut-off for discriminating between acute appendicitis and the controls was >11.41 ng/mL, with a sensitivity of 93.5%, but with a specificity for identifying appendicitis of 21.4%, good discriminative power (AUC = 0.880). For EP, the optimal cut-off was >93.20 ng/mL, with a sensitivity of 87%, but with a specificity of 14.3% (AUC = 0.901), excellent discriminative power. For the diagnosis of perforated AA, the discriminative power of ECP and EP serum concentrations are weak (AUC = 0.562 and AUC = 0.664, respectively). Concerning the presence of peritonitis, the discriminative power of ECP and EP serum concentrations is acceptable, respectively: AUC = 0.724 and AUC = 0.735. Serum levels of EDN (p = 0.119), ECP (p = 0.586) and EP (p = 0.08) in complicated appendicitis were similar to uncomplicated appendicitis. Serum concentrations of ECP and EP can be added to decision-making AA diagnosis. A Th2-type immune response is present in AA. These data bring forward the role of an allergic reaction in the pathogenesis of acute appendicitis.

Abstract
Mounting evidence suggests that acute appendicitis (AA) is not one but two diseases: complicated appendicitis, which is associated with necrosis leading to perforation or periappendicular abscess, and uncomplicated appendicitis, which does not necessarily result in perforation. Even though AA is the most frequent cause of surgery from abdominal pain, little is known about the origins and etiopathogenesis of this disease, much less regarding the different disease types. In this study, we investigated the microbiome (inter-domain amplicon and metagenome sequencing) of samples from the appendix, rectum and peritoneum of 60 children and adolescents with AA to assess the composition and potential function of bacteria, archaea and fungi. The analysis of the appendix microbial community revealed a shift depending on the severity of the AA. This shift was reflected by two major community state types that represented the complicated and uncomplicated cases. We could demonstrate that complicated, but not uncomplicated, appendicitis is associated with a significant local expansion of oral, bacterial pathogens in the appendix, most strongly influenced by necrotizing Fusobacterium spp., Porphyromonas and Parvimonas. Uncomplicated appendicitis, however, was characterized by gut-associated microbiomes. Our findings support the hypothesis that two disease types exist in AA, which cannot be distinguished beyond doubt using standard clinical characterization methods or by analysis of the patient's rectal microbiome. An advanced microbiome diagnosis, however, could improve non-surgical treatment of uncomplicated AA.

Abstract
This meta-analysis aims to evaluate the comparative outcomes of drain insertion versus no drain after appendicectomy for complicated appendicitis. A systematic search of PubMed, Cochrane Library and Scopus was conducted, and all studies comparing drain versus no drain after appendicectomy for complicated appendicitis were included. Abdominal collection, surgical site infection (SSI), bowel obstruction, faecal fistula, paralytic ileus, length of hospital stay (LOS) and mortality were the evaluated outcome parameters for the meta-analysis. Seventeen studies reporting a total number of 4,255 patients who underwent appendicectomy for complicated appendicitis with (n=1,580) or without (n=2,657) drain were included. There was no significant difference between the two groups regarding abdominal collection (odds ratio (OR)=1.41, P=0.13). No-drain group was superior to the drain group regarding SSI (OR=1.93, P=0.0001), faecal fistula (OR=4.76, P=0.03), intestinal obstruction (OR=2.40, P=0.04) and paralytic ileus (OR=2.07, P=0.01). There was a difference regarding mortality rate between the two groups (3.4% in the drain group vs 0.5% in the no-drain group, risk difference (RD)=0.01, 95% CI (-0.01, 0.04), P=0.36). In conclusion, this meta-analysis has shown that drains have no effect on the development of intra-abdominal collections in complicated appendicitis, but it can significantly increase the risk of postoperative complications such as fistula, surgical site infection (SSI), bowel obstruction, ileus and length of hospital stay.

Abstract
BACKGROUND Complicated appendicitis (CA) is defined as perforated appendicitis, peritonitis, peri-appendicular abscess, or appendicular mass. One-third of patients who develop appendicitis are diagnosed with CA at presentation. Studies regarding the prevalence of CA are lacking in low-income countries, and the characteristics of patients presented with CA are incoherently identified. OBJECTIVE To assess the prevalence and the significant characteristics associated with CA among patients admitted with the diagnosis of acute appendicitis at Adama Hospital Medical College. METHODS A cross-sectional study was conducted from January 1, 2018, up to December 31, 2019. From a total of 1043 patients during the study period, the charts of 431 patients were selected using a systematic random sampling technique. Data were collected by a structured checklist. Bivariate and multivariable binary logistic regression analyses were employed to assess the association of patients' characteristics with CA. RESULTS Out of 431 patients, 157 (36.4%) had CA. Characteristics of patients having a significant association with CA were found to be generalized abdominal tenderness (AOR: 27.48, 95% CI: 4.03, 187.24), diagnosis with peritonitis (AOR: 14.87, 95% CI: 4.05, 54.54), right lower quadrant (RLQ) abdominal mass (AOR: 7.79, 95% CI: 2.02, 29.99), shock (10.37, 95% CI: 3.18, 33.76), white blood cell (WBC) count >11,000 (AOR: 2.16, 95% CI: 1.02, 4.61), onset to visit interval of 8-14 days (AOR: 10.45, 95% CI: 2.4, 45.52) and ultrasound report of acute appendicitis (AOR: 0.33, 95% CI: 0.13, 0.85), appendiceal abscess (AOR: 5.05, 95% CI: 1.48, 17.31), and appendiceal mass (AOR: 6.04, 95% CI: 1.45, 25.14). CONCLUSION The prevalence of CA was very high. Generalized abdominal tenderness, RLQ abdominal mass, shock, WBC count, onset to visit interval, abdominopelvic ultrasound report, and clinical diagnosis of peritonitis were significantly associated with CA.

Abstract
Introduction Acute appendicitis can lead to perforation which can be lethal. The present study assessed the outcomes of laparoscopic appendectomy versus open appendectomy in patients with perforated appendicitis. Methodology A comparative study was conducted at the Department of Surgery, Liaquat University of Medical & Health Sciences (LUMHS), between March 2, 2019 and July 7, 2020. The inclusion criteria consisted of a diagnosis of perforated appendicitis. Exclusion criteria consisted of intellectual disability hindering the procurement of informed consent, pediatric patients < 15 years of age, patients with an appendicular mass or abscess unsuited for laparoscopic appendectomy, severe sepsis or septic shock on presentation, and pregnant women. Patients were allocated to either open appendectomy (Group A) or laparoscopic appendectomy (Group B). The data gathering proforma recorded demographics, surgical findings, operating room (OR) time, length of inpatient care, requirement of analgesic, and any adverse events following surgery. All of the surgeries were conducted by an experienced surgical consultant with an experience of at least five years. Results A total of 85 patients were included in the laparoscopic appendectomy group, while 101 cases were included in the open appendectomy group. The use of analgesics thrice a day to manage the postoperative pain was significantly associated with the open appendectomy (p < 0.0001). Moreover, the postoperative length of hospitalization was substantially greater in patients who underwent open appendectomy than those who underwent laparoscopic procedure (p < 0.0001). Wound-related complications were considerably lower in patients who had laparoscopic appendectomy as compared to those who had open appendectomy (23.53% versus 40.5%; p = 0.013). Conclusion The length of stay was significantly lower in patients who underwent laparoscopic appendectomy. Moreover, laparoscopic appendectomy was also associated with a lower rate of wound infection postoperatively, thus giving the former an edge over the latter. Despite the finding that the postoperative pain was not considerably different between the two groups, patients who underwent open appendectomy group required significantly more painkillers to manage the postoperative pain.

Abstract
BACKGROUND To compare the readmission rate, rate of urgent/unplanned visits to emergency, complication rate along with cost of health care among children and adolescents who were discharged the same day following a laparoscopic appendectomy and those who were not discharged on the same day. METHODS A systematic search was performed in the PubMed, Embase, and Scopus databases. Randomized controlled trials and studies, observational in design, were considered for inclusion. The included studies were conducted in children and adolescents with uncomplicated appendicitis undergoing laparoscopic appendectomy and compared outcomes of interest between patients that were discharged the same day (SDD group) following the operation and patients that were discharged within 2 days post-operatively (non-SSD group). Statistical analysis was performed using STATA software. Effect sizes were reported as pooled odds ratio (OR) or weighted mean difference (WMD) with 95% confidence intervals. RESULTS A total of 13 studies with 32,021 children and adolescents were included. There was no significant difference in the risks of unplanned visit to the emergency department (OR 1.07, 95% CI: 0.78, 1.47), readmission (OR 0.83, 95% CI: 0.66, 1.05), reoperation/re-intervention (OR 1.73, 95% CI: 0.19, 16.2) and complications (OR 0.84, 95% CI: 0.67, 1.06) in both groups of patients. Patients in the SDD group had slightly lower risk of wound infection/complication (OR 0.74, 95% CI: 0.57, 0.96) compared to patients in the non-SDD group. Those with SDD had to incur comparatively lesser hospital expense (in USD) compared to those with no SDD (WMD -2587.4, 95% CI: -4628.3, -546.6). CONCLUSION In children and adolescents with uncomplicated acute appendicitis undergoing laparoscopic appendectomy, same-day discharge is not associated with increased readmission risk, unplanned visits to emergency, and complications. Further, SDD is associated with lower cost of hospital care. Adoption of SDD in this subset of children and adolescents may be encouraged.

Abstract
BACKGROUND This study aims to compare the waiting and operating times of the patients who applied to our hospital with the diagnosis of acute appendicitis (AA) during the pandemic, how the process was managed in terms of AA and other data of the patient compared to the pre-pandemic period. METHODS A retrospective cohort analysis was performed among patients who were hospitalized in the Fatih Sultan Mehmet Training and Research Hospital General Surgery Clinic with a pre-diagnosis of AA. For this purpose, two groups were formed. Group 1: It comprised patients who were operated between March 11 and June 1, 2020; Group 2: It comprised patients who were operated between March 11 and June 1, 2019, with a pre-diagnosis of AA. RESULTS Forty-six patients in Group 1 and 79 patients in Group 2 were operated with the pre-diagnosis of AA. There was no difference between groups in terms of pre-operative symptom durations or surgery waiting times. CONCLUSION During the COVID-19 pandemic, significant decrease observed in the number of patients operated because of AA can be interpreted as the avoidance of patients from applying to the hospital with the concern of infection. Moreover, it may suggest that uncomplicated cases undergo spontaneous resolution; however, there is a requirement for further research to support this assumption and define the criteria for this condition by including a level of scientific evidence.

Cost-Utility Analysis of Antibiotic Therapy versus Appendicectomy for Acute Uncomplicated Appendicitis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18168473. [PMID: 34444222 PMCID: PMC8392297 DOI: 10.3390/ijerph18168473] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 08/03/2021] [Accepted: 08/06/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Current UK National Health Service (NHS) guidelines recommend appendicectomy as gold standard treatment for acute uncomplicated appendicitis. However, an alternative non-surgical management involves administrating antibiotic-only therapy with significantly lower costs. Therefore, a UK-based cost-utility analysis (CUA) was performed to compare appendicectomy with an antibiotic-only treatment from an NHS perspective. METHODS This economic evaluation modelled health-outcome data using the ACTUAA (2021) prospective multicentre trial. The non-randomised control trial followed 318 patients given either antibiotic therapy or appendicectomy, with quality of life (QOL) assessed using the SF-12 questionnaires administered 1-year post-treatment. A CUA was conducted over a 1-year time horizon, measuring benefits in quality adjusted life years (QALYs) and costs in pound sterling using a propensity score-matched approach to control for selection based on observable factors. RESULTS The CUA produced an incremental cost-effectiveness ratio (ICER) of -GBP 23,278.51 (-EUR 27,227.80) per QALY. Therefore, for each QALY gained using antibiotic-only treatment instead of appendicectomy, an extra GBP 23,278.51 was saved. Additionally, two sensitivity analyses were conducted to account for post-operative or post-treatment complications. The antibiotic-only option remained dominant in both scenarios. CONCLUSION While the results do not rely on a randomized sample, the analysis based on a 1-year follow-up suggested that antibiotics were largely more cost-effective than appendicectomy and led to improved QOL outcomes for patients. The ICER value of -GBP 23,278.51 demonstrates that the NHS must give further consideration to the current gold standard treatment in acute uncomplicated appendicitis.

The impact of COVID-19 pandemic lockdown on the incidence and outcome of complicated appendicitis. Surg Endosc 2021; 36:3460-3466. [PMID: 34312724 PMCID: PMC8313000 DOI: 10.1007/s00464-021-08667-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 07/20/2021] [Indexed: 12/28/2022]
Abstract
Background Patient attendance at emergency departments (EDs) during the COVID-19 pandemic outbreak has decreased dramatically under the “stay at home” and “lockdown” restrictions. By contrast, a notable rise in severity of various surgical conditions was observed, suggesting that the restrictions coupled with fear from medical facilities might negatively impact non-COVID-19 diseases. This study aims to assess the incidence and outcome of complicated appendicitis (CA) cases during that period. Methods A retrospective study comparing the rate and severity of acute appendicitis (AA) cases during the COVID-19 initial outbreak in Israel during March and April of 2020 (P20) to the corresponding period in 2019 (P19) was conducted. Patient data included demographics, pre-ED status, surgical data, and postoperative outcomes. Results Overall, 123 patients were diagnosed with acute appendicitis, 60 patients during P20 were compared to 63 patients in P19. The rate of complicated appendicitis cases was significantly higher during the COVID-19 Lockdown with 43.3% (26 patients) vs. 20.6% (13 patients), respectively (p < 0.01). The average delay in ED presentation between P20 and P19 was 3.4 vs. 2 days (p = 0.03). The length of stay was 2.6 days in P20 vs. 2.3 days in P19 (p = 0.4), and the readmission rate was 12% (7 patients) vs. 4.8% (3 patients), p = 0.17, respectively. Logistic regression demonstrated that a delay in ED presentation was a significant risk factor for complicated appendicitis (OR 1.139, CI 1.011–1.284). Conclusion The effect of the COVID-19 initial outbreak and Lockdown coupled with hesitation to come to medical facilities appears to have discouraged patients with acute appendicitis from presenting to the ED as complaints began, causing a delay in diagnosis and treatment, which might have led to a higher rate of complicated appendicitis cases and a heavier burden on health care systems.

Abstract
Background Acute appendicitis is the most common cause of acute abdomen surgery. Despite its commonness and the abundance of literature on the subject, its diagnosis remains challenging. Delay in intervention results in complications of the process leading to increased morbidity and mortality. Methodology An observational prospective cohort study was conducted, and all patients who had undergone appendectomy for a clinical diagnosis of appendicitis were included in the study. Data were analysed using Statistical Package for Social Sciences (SPSS) version 23. Results Half of the study participants were in the age range of 18–25 years with male preponderance (63.9%). The mean duration of symptoms was 51.3 hours. The most common presenting symptom was abdominal pain (98.2%), while right lower quadrant tenderness was the most common sign (93.4%). Abdominal ultrasound was done in 81% of the study population with a sensitivity and specificity of 95.7% and 33.3%, respectively. Three-quarters (74.4%) of the patients had uncomplicated appendicitis, while 1.8% had a grossly normal appendix. None of the appendectomy specimens were sent for pathology. The mean hospital stay was 3.2 days. The morbidity and mortality rate were 3.8% and 0.4%, respectively. Conclusion Acute appendicitis was the most common emergency surgical procedure in the study period. Abdominal ultrasound was used in the majority of the patients as supplementary imaging for the diagnosis of acute appendicitis. Uncomplicated appendicitis took the major share of the intraoperative finding leading to acceptable morbidity and mortality rates.

Abstract
BACKGROUND Acute appendicitis is one of the most common emergencies treated by general surgeons. The treatment of choice in the majority of cases is laparoscopic appendectomy. In the era of the COVID-19 pandemic, there is a concern for a delayed referral of patients and thus a more advanced presentation of the disease leading to a prolonged and complicated course. METHODS Retrospective review of a computerized database of patients who were admitted with acute appendicitis and underwent laparoscopic appendectomy during the COVID pandemic in a single tertiary center in Israel. Patients were compared with those who were admitted and operated for appendicitis in the same period in the previous year. RESULTS One hundred twenty-three patients underwent laparoscopic appendectomy in the study period in 2020, compared with 109 who had surgery in 2019. During the COVID pandemic 41 patients presented with complicated appendicitis versus 22 patients in 2019 (P=0.0174). The placement of peritoneal drains was more prevalent during the pandemic, 5.5% versus 11.4%, and the use of stapler device for appendicular stump closure (P=0.0105). CONCLUSIONS During the first stage of the COVID-19 pandemic, there was a significant increase in the rate of complicated appendicitis. Patients should be strongly encouraged not to refrain from medical treatment and go to the emergency room with the persistence of symptoms.

Abstract
BACKGROUND Approximately 30% of appendectomies are for complicated acute appendicitis (CAA). With laparoscopy, the main post-operative complication is deep abscesses (12% of cases of CAA, versus 4% for open surgery). A recent cohort study compared short and long courses of postoperative antibiotic therapy in patients with CAA. There was no significant intergroup difference in the post-operative complication rate (12% of organ/space surgical site infection (SSI)). Moreover, antibiotic therapy is increasingly less indicated for other situations (non-complicated appendicitis, post-operative course of cholecystitis, perianal abscess), calling into question whether post-operative antibiotic therapy is required after laparoscopic appendectomy for CAA. METHODS/DESIGN This study is a prospective, multicenter, parallel-group, randomized (1:1), double-blinded, placebo-controlled, phase III non-inferiority study with blind evaluation of the primary efficacy criterion. The primary objective is to evaluate the impact of the absence of post-operative antibiotic therapy on the organ/space surgical site infection (SSI) rate in patients presenting with CAA (other than in cases of generalized peritonitis). Patients in the experimental group will receive at least one dose of preoperative and perioperative antibiotic therapy (2 g ceftriaxone by intravenous injection every 24 h up to the operation) and metronidazole (500 mg by intravenous injection every 8 h up to the operation) and, in the post-operative period, a placebo for ceftriaxone (2 g/24 h in one intravenous injection) and a placebo for metronidazole (1500 mg/24 h in three intravenous injections, for 3 days). In the control group, patients will receive at least one dose of preoperative and perioperative antibiotic therapy (2 g ceftriaxone by intravenous injection every 24 h up to the operation) and metronidazole (500 mg by intravenous injection every 8 h up to the operation) and, in the post-operative period, antibiotic therapy (ceftriaxone 2 g/24 h and metronidazole 1500 mg/24 h for 3 days). In the event of allergy to ceftriaxone, it will be replaced by levofloxacin (500 mg/24 h in one intravenous injection, for 3 days). The expected organ space SSI rate is 12% in the population of patients with CAA operated on by laparoscopy. With a non-inferiority margin of 5%, a two-sided alpha risk of 5%, a beta risk of 20%, and a loss-to-follow-up rate of 10%, the calculated sample size is 1476 included patients, i.e., 738 per group. Due to three interim analyses at 10%, 25%, and 50% of the planned sample size, the total sample size increases to 1494 patients (747 per arm).
