Abstract Background Appendicectomy is a common emergency operation. The aim of this analysis was to study the effect of preoperative delay on disease progression, and whether a novel scoring system (Atema score) could be useful in predicting complicated appendicitis. Methods Patients with uncomplicated acute appendicitis on CT and who underwent appendicectomy in 2014–2015 were analysed for patient characteristics, preoperative delay and outcomes. Results Of 837 patients with uncomplicated appendicitis on CT, 187 (22.3 per cent) were found to have complicated appendicitis at surgery. The median time estimate for perforation was 25.4 h after CT, with an hourly rate of perforation of 2 per cent. Patients with an Atema score of 6 or less and those with no appendicolith on CT and a C-reactive protein level below 51 mg/l were the slowest to develop perforation, reaching a perforation rate of 5 per cent in 7.1 and 7.6 h respectively. Conclusion A substantial proportion of patients with uncomplicated acute appendicitis on CT have complicated appendicitis at surgery. However, in patients with no risk factors, surgery can be postponed safely for up to 7 h.

Objective: The objective of this research was to evaluate the diagnostic value of mean platelet volume/platelet count (MPV/PC) ratio in pediatric acute appendicitis. Methods: This retrospective study included a total of 310 patients, 176 in the uncomplicated appendicitis group, 80 in the complicated appendicitis group, and 54 in the nonspecific abdominal pain (NSAP) group. C-reactive protein (CRP) level, white blood cell (WBC) count, absolute neutrophil count (ANC), MPV, PC, and MPV/PC ratio were compared between the groups. Results: WBC and ANC levels differed significantly between the groups (P<0.001 in all pairwise comparisons). CRP levels in the complicated appendicitis group were higher than in the NSAP and uncomplicated appendicitis groups (P<0.001 for both comparisons). There was a negative correlation between MPV and PC (r= -0.434, P<0.001). Both PC and MPV/PC ratio were able to distinguish cases of complicated appendicitis from NSAP (P=0.047 and P=0.045, respectively) and from cases of uncomplicated appendicitis (P=0.010 and P=0.045, respectively). Areas under the ROC curve for CRP, WBC, ANC, MPV, PC, and MPV/PC ratio were 0.640, 0.690, 0.727, 0.553, 0.541, and 0.546, respectively. Conclusion: According to the results of our study, MPV/PC ratio can be used in addition to the conventional markers to discriminate cases of complicated appendicitis.

Background: Identification of complicated and uncomplicated acute appendicitis is important in children. In acute appendicitis, along with clinical evaluation and staging, many laboratory tests have been used. The aim of the study was to compare total leucocyte count in children with uncomplicated and complicated acute appendicitis in different age groups.Methods: Retrospective cohort study was performed in children who underwent appendicectomy, in a Government tertiary care institution between January 2017 and December 2018. 206 patients were divided into complicated and uncomplicated appendicitis. Total leucocyte count at time of admission was compared according to age. Unpaired t test and Chi-square test were used for statistical analysis.Results: There were 136 males and 70 females. 107 patients (51.94%) had complicated and 99 (48.06%) had uncomplicated appendicitis. Mean leucocyte count per µl in uncomplicated appendicitis was 18993±3540 in <5 years, 17155±3386 in 5-10 years and 15833±3613 in 10-15 years. The mean leucocyte count for complicated appendicitis was 19974±3658 in <5 years, 17727±4487 in 5-10 years and 17220±3411 in 10-15 years age group. In 10-15 years group, patients with complicated acute appendicitis had statistically significant higher values of mean total leucocyte count.Conclusions: Total leucocyte count can be used as marker of severity of acute appendicitis in children older than 10 years. In children with clinical suspicion of acute appendicitis, total leucocyte count >20000 per µl signifies complicated appendicitis in all age groups.

Abstract Background: No reliably specific marker for complicated appendicitis has been identified. Serum C-reactive protein (CRP) increases and albumin (ALB) decreases in patients with inflammation and infection. C-reactive protein and albumin ratio (CRP/ALB ratio) has been found associated with neonatal septicemia, inflammatory bowel disease and pancreatitis. However, its value in the diagnosis of complicated appendicitis has not been studied. The aim of this study was to evaluate the value of CRP/ALB ratio for predicting complicated appendicitis in children.Methods: A retrospective study of 232 children with acute appendicitis was conducted with assessment of age, gender, weight, symptom duration, albumin and blood routine indexes. According to intraoperative findings and postoperative pathological results, patients were divided into the simple appendicitis group (127 cases) and complicated appendicitis group (105 cases). SPSS version 17 was used to analyse the data.Results: Of the 232 patients, 118 (50.9%) were male and 114 (49.1%) were female. The age range was 1 to 15 years, the mean age of the patients was 8.30 ± 3.25 years. The CRP/ALB ratio was higher in complicated appendicitis compared with simple appendicitis(p<0.05). Logistic regression analysis showed that mononuclear cell (MC), CRP, procalcitonin (PCT) and CRP/ALB ratio were independent risk factors for complicated appendicitis in children. Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) of CRP/ALB ratio was higher than MC, PCT and CRP (0.946 vs 0.619 vs 0.843 vs 0.906). CRP/ALB ratio >1.43 was found to be a significant marker in predicting complicated appendicitis with 91.4 % sensitivity and 90.6 % specificity. Compared with CRP/ALB ratio=<1.43, patients with CRP/ALB ratio >1.43 had a 102.22 times higher chance of complicated appendicitis (95% CI:41.322 - 252.874).Conclusion: The CRP/ALB ratio is a novel and promising indicator to predict complicated appendicitis in children before operation，which is easy-to-measure and repeatable. Therefore, CRP/ALB ratio can provide a reference for the choice of surgical treatment for acute appendicitis in children.

Abstract Background: Complicated appendicitis is an indication for emergency surgery. Therefore, the predictive factors for appendicitis based on the patient background needs identification. Previously, factors predicting non-complicated and complicated appendicitis were reported. However, most of those reports were deemed unsuitable as a standard for emergency use, since those comprised too many items as predictors. We previously reported three items that preoperatively predicted complicated appendicitis (body temperature, C-reactive protein, and fluid retention around the appendix). In this study, we re-evaluated different cases to confirm the usefulness of these three items can for accurately predicting complicated appendicitis preoperatively. In addition, we compared the effectiveness of these predictor items with those reported by other researchers.Methods: We retrospectively evaluated 417 adult patients who underwent surgery for acute appendicitis between January 2013 and December 2019, and compared our predictor items with those used in previous reports on the preoperative prediction of complicated appendicitis (criteria A consisting of eight predictor items and criteria B consisting of seven predictor items). Results: The area under the receiver operating characteristic curve (AUC) for the sensitivity to diagnose complicated appendicitis according to our criteria, criteria A, and criteria B were 0.823, 0.839, and 0.856, respectively. The AUC of our criteria and criteria A were similar (P = 0.356); those of criteria A and B were also similar (P = 0.352). However, the AUC of criteria B was statistically higher than that of our criteria (P < 0.05).Conclusion: Diagnostic criteria B were statistically the best predictor items for characterizing complicated and uncomplicated appendicitis. However, like criteria A and B, the AUC of our criteria exceeded 0.8, and only involved three predictor items; therefore, they can be considered useful predictors.

Introduction The purpose of this study is to evaluate the diagnostic value of C-reactive protein (CRP) to identify complicated appendicitis (defined as perforation, abscess or gangrenous appendicitis) versus simple appendicitis. Methods A retrospective study was performed in the emergency department (ED) of Prince of Wales Hospital in the New Territories of Hong Kong. The clinical records of patients admitted to the surgical wards via the ED over 17 months were reviewed by a research assistant. We included all patients aged >13 years who had a provisional diagnosis of “acute appendicitis” or “right lower quadrant pain”. We excluded patients with pregnancy, previous appendicectomy, incomplete medical records or no CRP levels determined before operation and those who discharged themselves from hospital against medical advice after admission. The outcome of this study was the CRP level in relation to the presence of complicated appendicitis. ROC curve analysis was employed to identify the optimum cut-off level of CRP which had the best sensitivity and specificity to identify complicated appendicitis compared to simple appendicitis. Results Forty-two patients were diagnosed to have acute appendicitis, 31 of whom had complicated appendicitis. CRP level was higher in the group of complicated appendicitis (p<0.05). We identified an optimum cut-off value for CRP of 40.1 mg/L to discriminate between complicated and non-complicated appendicitis. The sensitivity and specificity of CRP to identify complicated appendicitis were 71.0% and 100% respectively at this cut-off level. Conclusion High CRP levels could possibly predict the diagnosis of complicated appendicitis and facilitate more appropriate surgical care. This finding needs to be confirmed in prospective and larger multicentre studies. (Hong Kong j.emerg.med. 2014;21:354-360)

SummaryIntroductionAcute appendicitis (AA) – acute inflammation and infection of the appendix – is one of the most common cause for abdominal surgery in pediatrics. Appendectomy has been the gold standard since 1735, but in recent years there have been several studies that investigate antibacterial therapy for uncomplicated acute appendicitis. In 2016 new recommendations for suspected AA were implemented in emergency department setting of Children's Clinical University Hospital (CCUH).Aim of the StudyTo evaluate whether diagnostic criteria for patients with a suspected acute appendicitis is effective as a diagnostic tool and to evaluate whether dual antibacterial therapy is safe and effective as first line treatment for children with diagnosis of uncomplicated acute appendicitis in CCUH.Material and methodsA retrospective study was made in CCUH from January 2017 to December 2017. Patients aged 7 to 18 with suspected uncomplicated acute appendicitis were identified and data were collected from an internal hospital management system and patients’ medical records. Patients were divided into two groups – A and B. In group A were patients who met the criteria of uncomplicated AA, and in group B – patients who met the criteria of complicated AA. Both groups received ampicillin and metronidazole. For statistical analysis IBM SPSS Statistics 22 program was used.ResultsFrom 98 patients majority were boys (51% (n=50)) with mean age 12.6 years. As a result of antibacterial therapy clinical condition improved in 93% (n=89) of patients who were discharged without surgery. 7 patients did not improve and underwent surgery within 48 hours after admission, another 2 had elective appendectomy. There was a significant positive moderate correlation between C–reactive protein (CRP), white blood cell count (WBC), basophil granulocytes (BASO) and appendix diameter at admisson and after 48 hours of dual antibacterial therapy (r=0.31, p=0.003 vs. r=0.37, p<0.001 vs. r=0.41, p=0.017 vs. r=0.51, p=0.013). In group A (68% (n=67)) there was a significant positive moderate correlation between CRP, WBC and appendix diameter at admission and after 48 hours of dual antibacterial therapy (r=0.31, p=0.003 vs. r=0.37, p<0.001 vs. r=0.51, p=0.013). In group B (30% (n=31)) 7 patients underwent appendectomy and 2 patients received a broad spectrum antibacterial therapy prior to elective appendectomy. There is evidence of significant association between ALVARADO score (p=0.004), rebound tenderness (p<0.001), WBC (p=0.004), CRP (p<0.001) and stage in which appendicitis has progressed to.ConclusionsAntibiotic-alone treatment may be a safe and effective initial management choice in children with uncomplicated acute appendicitis. However, to fully evaluate effectiveness of antibacterial therapy and diagnostic criteria, further follow–up research is needed.A normal C–reactive protein value does not rule out uncomplicated acute appendicitis, therefore it can not act as a single marker to diagnose AA or to differentiate between complicated and uncomplicated AA.Recommendations of treatment of UCAA are acceptable for use in emergency department as they act as a unified tool that allows pediatricians and pediatric surgeons to quickly assess suspected acute appendicitis.

Aim The main goal of our study was to assess a 7 days long course of antibiotics for acute uncomplicated appendicitis. Materials and Methods From March 2014 to November 2015, all patients diagnosed with acute appendicitis have been considered to be treated by only antibiotics. Inclusion criteria included clinical (tenderness), biological (C-reactive protein [CRP] < 50), and radiological features (diameter > 6 mm). All patients were treated with intravenous amoxicillin and clavulanic acid (100 mg/kg/day) for 2 days (six doses). At the end of the treatment, clinical and paraclinical examinations included blood samples at day 7 and ultrasound (US) scan at 3 months. Results A total of 166 patients were treated and followed up prospectively during the study period. Mean age at diagnosis was 10.8 ± 0.6 years. All children, but four were discharged with a clinical improvement after 48 hours and six intravenous antibiotics injection according to our protocol. Four children required surgery during the initial hospitalization period.Initial ultrasound scan showed a mean diameter of 7.85 ± 1.6 mm, with inflamed fat in 124 patients (74.7%). At Day 7, the diameter was 5.2 ± 1.6 mm (p < 0.0001).During a median follow-up of 18.8 months (3.5–18), 22 patients (13.25%) had to be managed for a novel episode of acute appendicitis after a median period of 138 days (13–270). None had to be managed for a complicated appendicitis. Conclusion Non-operative treatment (NOT) is a safe alternative for the management of uncomplicated acute appendicitis in children. Further study should be conducted to determine relapse risk factors.

The purpose of this study was to determine whether the Alvarado score is beneficial in identifying complicated versus uncomplicated acute appendicitis in elderly patients. A retrospective review was conducted of patients aged 65 years and older who underwent an appendectomy for pathologically confirmed appendicitis. A review of 310 operative reports and patient charts from October 2012 to December 2016 yielded 216 patients. Patients were grouped based on complicated versus uncomplicated appendicitis. One hundred ten patients had complicated appendicitis, whereas 106 patients were uncomplicated. Among the complicated appendicitis patients, 76.4 per cent were perforated, 38.2 per cent were gangrenous, and 34.5 per cent had an abscess. The complicated appendicitis group had a higher mean duration of symptoms (2.70 ± 3.41 days vs 2.09 ± 3.08 days, P = 0.011). Appendectomies that were open or converted to open were more likely to be associated with complicated appendicitis (75% vs 48%, P = 0.012). Mean hospital length of stay was greater in those with complicated appendicitis (5.34 ± 5.56 days vs 3.12 ± 2.86 days, P < 0.001). The two groups did not differ on mean Alvarado score (complicated = 6.96 ± 1.99 vs uncomplicated = 6.72 ± 1.85, P = 0.36). Only 62.5 per cent of patients had an Alvarado score that met the cutoff for acute appendicitis. The Alvarado score was not able to differentiate complicated from uncomplicated appendicitis in elderly patients.

Abstract Background The diagnosis of acute appendicitis in children is quite challenging as the rate of negative appendectomy varies between 15 and 57%. Increased utilization of imaging diagnostic facilities in advanced countries seems to have reduced the incidence of operating on normal appendix to a single digit. In low- and middle-income countries, the incidence remains unacceptably high (double digits). Inflammatory markers and scoring systems may be a suitable adjunct to increase diagnostic yield in most third world countries. Thus, the aim of this study was to evaluate the diagnostic value of Alvarado score, white blood cell count, and serum C-reactive protein in children with acute appendicitis. Results The ages of patients ranged between 4 and 15 years with a mean of 11.2 ± 2.8 years. The male to female ratio was 1.4 to 1.0. Nineteen percent of patients had negative appendiceal findings on histological examination. The sensitivity and specificity of Alvarado score, C-reactive protein estimation, total white blood cell count in diagnosing acute appendicitis were 86.4% and 63.2%, 98.8% and 36.8%, and 51.9% and 89.5% respectively. Alvarado score has the highest area under ROC curve analysis 0.824, 95% CI of 0.724 to 0.924 compared with CRP, 0.769. 95% CI of = 0.647 to 0.891 and WBC count, 0.765, 95% CI of 0.643 to 0.887. Both CRP and WBC count showed higher discriminatory values between complicated and uncomplicated appendicitis, p < 0.001. Conclusion Alvarado score outperformed other tests in setting the diagnosis of acute appendicitis. However, none of the tests can be relied on wholly for operative decision. Clinical judgement remains the bedrock for diagnosis and operative management.
