Abstract
There are two types of treatment for acute appendicitis (AA): surgery and antibiotic therapy. Some patients with complex appendicitis are treated with surgery; however, for uncomplex appendicitis, most could be treated effectively with antibiotics instead. How to distinguish complex appendicitis from uncomplex appendicitis before surgery is currently unknown. The present study aimed to assess the efficacy of the laboratory parameters to diagnose complicated appendicitis. Data from 1,514 cases with acute appendicitis who were admitted to Beijing Tsinghua Changgung Hospital and Beijing Aerospace General Hospital (both Beijing, China) from January 2016 to September 2021 were retrospectively analyzed. All cases were divided into uncomplicated and complicated appendicitis. Independent variables were analyzed by uni- and multivariate logistic regression analyses. Receiver operating characteristic (ROC) curve analysis was used to identify significant parameters in the multivariate logistic regression analysis. Cut-off values, sensitivity, specificity and accuracy with area under the curve (AUC)>0.600 were considered significant parameters. Significant differences were found in age (P<0.001), body temperature (P<0.001), white blood cell (WBC) count (P<0.001), C-reactive protein (CRP; P<0.001), neutrophil count (P<0.001), neutrophil-to-lymphocyte ratio (NLR, P=0.019), platelet-to-lymphocyte ratio (PLR, P<0.001), platelet count (P<0.001), coefficient of variation (CV) and standard deviation (SD) of red blood cell distribution width (RDW); both P<0.001), mean platelet volume (MPV, P<0.001) and total (P<0.001) and direct bilirubin (P<0.001) between the two groups. CRP, neutrophil count, NLR, PLR, platelet count, RDW-CV, RDW-SD, MPV and direct bilirubin levels were found as the independent variables to diagnose complicated appendicitis. In patients with acute appendicitis, CRP >22.95 mg/l, NLR >5.7, serum direct bilirubin >6.1 mmol/l and RDW-SD>17.7 fl were significantly associated with complicated appendicitis.

Abstract
BACKGROUND Acute appendicitis is a common surgical emergency worldwide. Recent studies on hematological inflammatory markers concerning acute appendicitis have shown variable results. AIMS The aim of this study was to evaluate pre-operative values of platelet indices such as mean platelet volume (MPV) and platelet distribution width (PDW), and red cell distribution width (RDW) in relation to the diagnosis of acute appendicitis and their efficacy as predictors of appendicular perforation. METHODS A prospective observational study of 190 patients diagnosed with appendicitis and who underwent an appendectomy was undertaken and confirmed histopathologically. Preoperatively, blood samples of white blood cells (WBCs), platelet count, MPV, PDW, and RDW were analyzed using a Sysmex XN1000 analyzer machine. RESULTS Of 190 patients, 169 had acute appendicitis, and 21 had perforated appendicitis. The mean age of patients was 28.04 ± 14.2 years. The male-to-female ratio was 1.5:1. The WBC (p<0.05), MPV (p<0.05), and PDW (p<0.05) were found to have higher statistically significant values in acute appendicitis and perforated appendicitis compared to the RDW (p>0.05). However, perforated appendicitis had a higher RDW value compared to acute appendicitis, which can be a predictive factor. CONCLUSIONS The elevated value of MPV and PDW associated with leukocytosis can be used as supportive evidence for the clinical and radiological diagnosis of acute appendicitis and appendicular perforation. Thus, these values can be used as diagnostic cost-effective inflammatory biomarkers.

Abstract
Background An accurate diagnosis and timely surgical intervention have significant importance in noncomplicated appendicitis (NCA) and complicated appendicitis (CA). Therefore, any factor that helps in the prediction of CA also contributes to suitable treatment options. Aim This retrospective study aimed to identify any relationship between acute appendicitis (AA) and preoperative blood test levels and whether these parameters can differentiate between NCA and CA patients. Patients and Methods A database of 201 appendectomies and 100 control healthy patients was analyzed between 2019 and 2022. Patients were divided into three groups: NCA without peritonitis or phlegmonous appendicitis as group 1; CA with perforated, necrotizing appendicitis with peritonitis as group 2; and the healthy control group (CG) as group 3. White blood cell (WBC), platelet distribution width (PDW), mean platelet volume (MPV), red cell distribution width (RDW), creatine kinase (CK), and bilirubin levels were collected from the patients and compared statistically between the groups. Results Age, WBC, and PDW levels were set as predictive in the differential diagnosis of CA as a result of receiver operating characteristic (ROC) analysis. The multivariate analysis demonstrated that age (OR: 1.023; 95% CI: 1.000-1.045; P = 0.04), male sex (OR: 3.718; 95% CI: 1.501-9.213; P = 0.005), WBC levels (OR: 1.000; 95% CI: 1.000-1.000; P = 0.002), and PDW levels (OR: 2.129; 95% CI: 1.301-3.484; P = 0.003) were independently associated with CA. Conclusion Age, higher WBC count, and PDW levels are valuable in differentiating the diagnosis of CA from NCA, and this could be a feasible approach for surgical decisions.

Abstract
PURPOSE Appendicitis is a common cause of acute abdominal pain, and treatment with laparoscopy has become increasingly common during the past two decades. Guidelines recommend that normal appendices are removed if operated for suspected acute appendicitis. It is unclear how many patients are affected by this recommendation. The aim of this study was to estimate the rate of negative appendectomies in patients undergoing laparoscopic surgery for suspected acute appendicitis. METHODS This study was reported following the PRISMA 2020 statement. A systematic search was conducted in PubMed and Embase for retrospective or prospective cohort studies (with n ≥ 100) including patients with suspected acute appendicitis. The primary outcome was the histopathologically confirmed negative appendectomy rate after a laparoscopic approach with a 95% confidence interval (CI). We performed subgroup analyses on geographical region, age, sex, and use of preoperative imaging or scoring systems. The risk of bias was assessed using the Newcastle-Ottawa Scale. Certainty of the evidence was assessed using GRADE. RESULTS In total, 74 studies were identified, summing up to 76,688 patients. The negative appendectomy rate varied from 0% to 46% in the included studies (interquartile range 4-20%). The meta-analysis estimated the negative appendectomy rate to be 13% (95% CI 12-14%) with large variations between the individual studies. Sensitivity analyses did not change the estimate. The certainty of evidence by GRADE was moderate due to inconsistency in point estimates. CONCLUSION The overall estimated negative appendectomy rate after laparoscopic surgery was 13% with moderate certainty of evidence. The negative appendectomy rate varied greatly between studies.

Abstract
Background Acute appendicitis (AA) is one of the most common emergency surgery. Aim To evaluate the performance of laboratory parameters used in the diagnosis of AA. Subjects and Methods There were two groups. In both groups, leukocyte (WBC), neutrophil, lymphocyte count, neutrophil/lymphocyte ratio (NLR), mean platelet volume (MPV), red cell distribution width (RDW), and platelet distribution width (PDW) values were examined in complete blood count (CBC). In addition, serum bilirubin (total bilirubin and direct bilirubin) values were examined. All laboratory parameters studied were compared to evaluate their diagnostic performance. Results A total of 128 people were in the AA group and 122 people were in the healthy group (control). WBC count, neutrophil count, NLR, total bilirubin, direct bilirubin, and PDW values were significantly higher in the AA group than in the control group (P value <0.05). Lymphocyte counts and MPV values in the AA group were significantly lower than in the control group (P value <0.05). The sensitivity and selectivity of the WBC and neutrophil counts in AA were 95.13%, 89.34%, 94.53%, and 93.44%, respectively. The sensitivity and selectivity of the total bilirubin values were 59.38% and 73.77%, respectively. Area under the ROC curve (AUC) values within 95% confidence interval were over 0.900 for neutrophil count, WBC count, direct bilirubin, NLR, and PDW values. AUC values for total bilirubin, lymphocyte count, RDW, and MPV values were below 0.700. Conclusions Diagnostic performances of the laboratory parameters were determined as follows: neutrophil count > WBC count > direct bilirubin = NLR = PDW > total bilirubin = lymphocyte count = RDW = MPV.

Abstract
BACKGROUND Platelet distribution width (PDW) is a predictor for all-cause mortality in patients with cardiovascular diseases (CVD). This study aimed to evaluate the prognostic implication of PDW in predicting cardiovascular and all-cause mortality in patients undergoing peritoneal dialysis (PD). METHODS In total, 762 PD patients from a single center were recruited retrospectively from 2005 to 2017 and followed up until 2021. The primary and secondary outcomes were cardiovascular and all-cause mortality, respectively. Survival analysis was conducted using Kaplan-Meier estimates and Cox regression analysis. RESULTS During a median of 52.2 months of follow-up, 135 (17.7%) cases of CVD and 253 (33.2%) cases of all-cause mortality were reported. After multivariate adjustment, high levels of PDW were associated with an increased risk of death from CVD (HR: 1.583; 95% CI: 1.109-2.258; P = 0.011) and all-cause mortality (HR: 1.313; 95% CI: 1.006-1.758; P = 0.045). Subgroup analysis indicated a stronger association between PDW and all-cause mortality among female participants (P-value for interaction = 0.033). Higher levels of PDW predicted an increased risk of all-cause mortality in female patients (HR: 1.986; 95% CI,1.261-3.127). CONCLUSION High levels of PDW are independently associated with cardiovascular and all-cause mortality in the PD population, and differences by sex exist in the association of PDW with all-cause mortality.

Abstract
PURPOSE This study aimed to examine the diagnostic value of IL-6, thiol-disulfide homeostasis, complete blood count and inflammatory biomarkers in the prediction of acute appendicitis in children. METHODS The study was designed as a prospective and controlled study in children-the study was conducted at a tertiary referential university hospital between May 2020 and April 2021. Patients were divided between study groups and one control group (CG): 1: confirmed acute appendicitis group (AAP); 2: perforated appendicitis group (PAP); and 3: non-specified abdominal pain (NAP). The age and gender of the patients were determined. The following listed laboratory parameters were compared between groups: TOS: total oxidative status, TAS: total antioxidant status, OSI: oxidative stress index, TT: total thiol, NT (µmol/L): native thiol, DIS: disulfide, IL-6: interleukin 6, TNF-a: tumor necrosis factor-alpha, WBC: white blood cell, NEU: neutrophil, NEU%: neutrophil percentage, LY: lymphocyte, LY%: lymphocyte percentage, PLT: platelet, MPV: mean platelet volume NLR: neutrophil lymphocyte ratio, CRP: C-reactive protein, LCR: lymphocyte CRP ratio, and serum lactate. RESULTS The TOS level of the PAP group was found to be significantly higher than that in the AAP, NAP and control groups (p = 0.006, < 0.001 and p < 0.001). TAS, TT, and NT levels in the PAP group were significantly lower than those in the AAP, NAP and control groups. OSI was significantly higher in the PAP group than in the other groups. The TT and NT levels of the NAP group were both similar to those of the control group. Serum DIS level was similar between the AAP and PAP groups, AAP and NAP groups, and NAP and control groups. Serum IL-6 and TNF-α levels were found to be significantly higher in the PAP group compared to those in all groups. The WBC, NEU, and NEU% values were found to be significantly higher in the PAP group than those in the NAP and control groups, while LY and LY% values were found to be significantly lower. PAP and AAP groups were found to be similar in terms of WBC, NEU, LYM, NEU%, and LYM% values. PLT and MPV values and serum lactate values did not show a significant difference between the groups. NLR was similar in the AAP and PAP groups. A significant increase in CRP versus a decrease in LCR was detected in the PAP group compared to that in the AAP group. Multivariate analysis demonstrated that only IL-6 has significant estimated accuracy rates as 80% for the control group, 78.8% for AAP, 96.9% for PAP, and 81.6% for NAP. CONCLUSION Rather than AAP, PAP caused significantly higher oxidative stress (increased TOS and OSI), and lower antioxidation capacity (decreased TT and NT). IL-6 levels can provide a significant stratification. Nevertheless, simply detecting WBC or CRP is not enough to distinguish the specific pathology in acute appendicitis and related conditions.

Hyperbilirubinemia and Hyponatremia as Predictors of Complicated Appendicitis. Med Sci (Basel) 2022; 10:medsci10030036.

Abstract
Several studies have reported elevated serum bilirubin or reduced serum sodium levels in patients with complicated appendicitis (CA). This study examined the efficacy of hyperbilirubinemia, hyponatremia, and both combined in the preoperative diagnosis of CA. Patients who underwent surgery for acute appendicitis were included in this retrospective review. In total, 247 patients were included in the final analysis. Of these, 36 (14.2%) had early appendicitis, 177 (72.0%) had acute suppurative appendicitis, 32 (13.0%) had necrotizing/gangrenous acute appendicitis, and 2 (0.8%) had other types of appendicitis. The mean total bilirubin (TBIL) level was significantly higher in patients with CA than in those with uncomplicated appendicitis. Conversely, the mean serum sodium level was significantly lower in patients with CA than in those with uncomplicated appendicitis. The levels of TBIL (odds ratio: 1.098, 95% CI: 1.052–1.147) and serum sodium (odds ratio: 0.743, 95% CI: 0.646–0.855) were associated with CA. Hyponatremia combined with hyperbilirubinemia yielded significant discriminatory value for the diagnosis of CA. TBIL and serum sodium levels can be considered as adjuvant parameters in the diagnosis of perforated/necrotizing appendicitis. Although hyperbilirubinemia and hyponatremia together were better able to determine the risk of CA than either marker alone, other markers are required to definitively predict CA. Furthermore, large-scale studies are needed to confirm these findings.

Abstract
BACKGROUND: Appendicitis is an undesirable diagnosis, and the Alvarado score (AS) alone is insufficient in recognizing it. Many novel laboratory indicators, such as leukocytes and mast cells, differentiate.
AIM: Our objective was to demonstrate that mast cells had a greater influence on appendicitis severity than the AS, neutrophils, and platelets.
MATERIALS AND METHODS: An observational research in which 35 individuals with acute appendicitis at our institutions were identified for the appendix grade and allocated to one of two groups: Complicated or non-complicated. The AS and white blood cell count were calculated using the neutrophil-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), thrombocyte-to-neutrophil ratio (TNR), and total leukocyte. Mast cell count and granulation are evaluated using pathological anatomy.
RESULTS: TLR could not distinguish between severe appendicitis and others, but some showed potential. NLR, TNR, total leukocyte, ASs, mast cell count, and degranulation demonstrated good sensitivity-specificity values.
CONCLUSIONS: Mast cells have the potential to become a promising approach for predicting complicated pediatric appendicitis.

Background: Despite great advances in medicine, numerous available laboratory markers, and radiological imaging, the diagnosis of acute appendicitis (AA) in some cases still remains controversial and challenging for clinicians. Because of that, clinicians are still looking for an ideal marker that would be specific to AA. The red blood cell distribution width (RDW) has been recently investigated in several studies as a potential biomarker for AA. The aim of this systematic review and meta-analysis was to systematically summarize and compare all relevant data on RDW as a diagnostic biomarker for AA. Methods: This systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Scientific databases (PubMed, Scopus, Web of Science, and Excerpta Medica database—EMBASE) were systematically searched for relevant comparative studies by two independent researches using keywords ((red cell distribution width) OR rdw) AND (appendicitis). An independent assessment of the methodological quality was performed by two authors using the Downs and Black scale. RevMan 5.4 software was used to perform the meta-analysis. Results: Fifteen studies were included in the final meta-analysis; the majority of the studies was retrospective. Nine studies compared the RDW values between AA and non-AA; four studies compared the same between AA and healthy controls, while two studies compared the RDW values among all three groups. The estimated heterogeneity among the studies for all outcome was statistically significant (I2 = 92−99%, p < 0.00001). The pooling the data demonstrated no statistically significant difference in the RDW values (weighted mean difference (WMD) = 0.03, 95% CI = (−0.46, 0.52), p = 0.91) between AA and healthy controls as well as between AA and non-AA cases (WMD = 0.23, 95%CI = (−0.19, 0.65), p = 0.28). A separate subanalysis was performed to evaluate the utility of this biomarker for the pediatric age group. Pooling the data demonstrated no significant difference among the AA and non-AA groups in terms of the RDW values (WMD = 0.99, 95% CI = (−0.35, 2.33), p = 0.15). Conclusion: The RDW value difference demonstrated no statistically significant difference in AA versus healthy individuals and AA versus non-AA individuals. At the moment, there is no evidence of RDW utility in diagnostic testing of AA. Further research with prospective, multicenter studies and studies targeting special patient groups with a large sample size are needed in this field.

Abstract
The aim of this study is to evaluate and compare the diagnostic ability of platelet-related parameters and white cell-based parameters in pregnant women with appendicitis. This is a retrospective case-controlled study. Women aged between 18 and 50-years-old who had undergone appendectomy between January 2010 and January 2021 were enrolled in the study. Age, pathological diagnosis and relevant laboratory parameters were recorded for each patient. Gestational characteristics were recorded for pregnant patients. There were 58 pregnant and 1171 non-pregnant women enrolled. Pregnant women with acute appendicitis were significantly younger (p < .0001, d= -0.532), had significantly lower PLT (p = .002, d= -0.428) and ALC (p = .033, d= -.304) levels but had significantly higher MPV (p = .004, d = .415) levels than non-pregnant counterparts. In pregnant women, only MPV was the independent predictor of acute appendicitis (OR: 1,952). MPV cut-off value of 9,6 fL provided 63,5% sensitivity, 67,7% specificity, 94,2% PPV and 17,3% NPV whereas 10 fL provided 55,8% sensitivity, 100% specificity, 100% PPV and 21,4% NPV for acute appendicitis in pregnant women. Therefore, MPV might be useful for diagnosing acute appendicitis in pregnant women.Impact statementWhat is already known on this subject? In pregnant women, counts and percentages of white blood cells and neutrophils are known to be independent predictors of acute appendicitis. Meanwhile, physiologic leukocytosis of gestation is a challenge for interpretation of these parameters. Platelets and related markers are, as well, predictive for inflammatory processes in the human body.What do the results of this study add? The role of platelet-related markers in the diagnosis of acute appendicitis in pregnant women has not been studied previously. The results of the present study indicate that in pregnant women, changes in mean platelet volume might be an independent predictor of acute appendicitis.What are the implications of these findings for clinical practice and/or further research? Further similar large-scale case-controlled or cohort studies are required to validate the present results. In pregnant women with abdominal pain, the use of mean platelet volume as a biomarker could reduce negative laparotomy rates. A mean platelet volume is a useful tool for diagnosing acute appendicitis in pregnant women and provides helpful guidance for clinicians dealing with these patients in the emergency room.

Dalbaşı E, Akgül ÖL. Are average platelet volume, red cell distribution width and platelet distribution width guiding markers for acute appendicitis treatment options? Int J Clin Pract 2021; 75:e14232.

Abstract
BACKGROUND Acute appendicitis (AA) is the most common cause of surgery performed for the acute abdomen. The standard treatment for AA patients has been appendectomy for more than a century. The use of broad-spectrum antibiotics, the medical treatment option has come to the fore in the treatment of uncomplicated AA. AIM Evaluate whether white blood cell (WBC), platelet count, mean platelet volume (MPV), platelet distribution width (PDW), red cell distribution width (RDW) and C-reactive protein (CRP) values of patients diagnosed with uncomplicated AA clinically, with laboratory tests and radiologically with abdominal computed tomography (CT) could be a marker for choosing medical or surgical treatment. MATERIALS AND METHODS 519 patients aged between 20 and 65 years who were diagnosed with uncomplicated AA by abdominal CT in our centre between January 2016 and January 2019 were retrospectively analysed. The presence of at least one of the criteria of 7 mm or more appendix diameter and oedema or fluid accumulation around the appendix was accepted as uncomplicated AA. After the diagnosis of AA, 223 patients were treated medically, while 296 patients underwent laparoscopic appendectomy. The first group included patients who were treated medically and the second group included patients who underwent laparoscopic appendectomy. RESULTS Group 2 patients had higher mean platelet count (P < .005) and RDW (P = .003) values compared to Group 1 patients, while mean PDW (P < .001) values were lower compared to those of Group 1 patients. The differences between the mean WBC, CRP and MPV values of the groups were not statistically significant (P > .05). CONCLUSIONS Recently, studies supporting antibiotic therapy have been conducted in patients diagnosed with AA. As a result, we think that PDW, RDW, and platelet values in patients diagnosed with uncomplicated AA may be a guide in choosing patients to be treated with surgery or antibiotics.

Abstract
INTRODUCTION Acute appendicitis is one of the most common surgical emergencies worldwide. Clinical scoring system systems have been developed to diagnose acute appendicitis, but insufficient to predict the complication. The amount of serum biomarkers elevates in response to acute inflammation, which could be beneficial for diagnostic tools. Accordingly, a meta-analysis was conducted to evaluate the efficacy of platelet indices, including mean platelet volume (MVP) and platelet distribution width (PDW) as potential biomarkers for the diagnosis of a diagnosis of acute appendicitis. MATERIAL AND METHODS The dataset was defined by searching for articles published until December 2020 from PubMed, EMBASE, Google Scholar and the Cochrane database. The meta-analysis was performed using Review Manager Software version 5.4.1. RESULTS The final analysis was made from 9 studies, including 3124 patients. The results demonstrated that lower MPV values was significantly associated with acute appendicitis (odds ratio (OR) = 0.81, 95% confidence interval (CI) = -1.51 to -0.11, P = 0.02), but not associated with complicated appendicitis by comparing it with the control (OR = -0.13,95% CI = -0.33 to -0.07, P = 0.19) and non-complicated appendicitis groups (OR = -0.13,95% CI = -0.30 to -0.04, P = 0.14). The present study failed to demonstrate the diagnostic value of PDW for the prediction of appendicitis and its complication. CONCLUSION The results of the meta-analysis strongly indicate that a lower MVP values could function as a marker for predicting the acute appendicitis.

Abstract
BACKGROUND Emergency abdominal surgery in the elderly represents a global issue. Diagnosis of AA in old patients is often more difficult. Appendectomy remains the gold standard of treatment and, even though it is performed almost exclusively with a minimally invasive technique, it can still represent a great risk for the elderly patient, especially above 80 years of age. A careful selection of elderly patients to be directed to surgery is, therefore, fundamental. The primary aim was to critically appraise and compare the clinical-pathological characteristics and the outcomes between oldest old (≥ 80 years) and elderly (65-79 years) patients with Acute Appendicitis (AA). METHODS The FRAILESEL is a large, nationwide, multicentre, prospective study investigating the perioperative outcomes of patients aged ≥ 65 years who underwent emergency abdominal surgery. Particular focus has been directed to the clinical and biochemical presentation as well as to the need for operative procedures, type of surgical approach, morbidity and mortality, and in-hospital length of stay. Two multivariate logistic regression analyses were performed to assess perioperative risk factors for morbidity and mortality. RESULTS 182 patients fulfilled the inclusion criteria. Mean age, ileocecal resection, OAD and ASA score ≥ 3 were related with both overall and major complication. The multivariate analysis showed that MPI and complicated appendicitis were independent factors associated with overall complications. OAD and ASA scores ≥ 3 were independent factors for both overall and major complications. CONCLUSIONS Age ≥ 80 years is not an independent risk factor for morbidities. POCUS is safe and effective for the diagnosis; however, a CECT is often needed. Having the oldest old a smaller functional organ reserve, an earlier intervention should be considered especially because they often show a delay in presentation and frequently exhibit a complicated appendicitis.

Platelet indices in patients with acute appendicitis: a systematic review with meta-analysis. Updates Surg 2021; 73:1327-1341.

Abstract
Correlation between blood inflammatory parameters and acute appendicitis (AA) remains controversial. This meta-analysis aims to evaluate whether platelet (PLT) indices including mean platelet volume (MPV), PLT count, and platelet distribution width (PDW) are associated with AA. Pubmed, Embase, and Cochrane Library databases were searched for observational studies published from inception through April 2020 by two independent investigators. Studies reporting associations between platelet indices and AA were selected for inclusion. Standardized mean difference (SMD) and 95% confidence interval (CI) were estimated for continuous outcomes using a DerSimonian-Laird random-effects model. Of 842 records identified, 17 studies with a total of 6793 subjects met our inclusion criteria. Meta-analysis indicated that compared with those in healthy controls, significant decrease in MPV levels was observed in subjects with AA (SMD - 0.34; 95% CI - 0.56 to - 0.12; P = 0.003). Subgroup analyses represented a significant reduction of MPV levels in patients aged ≥ 30 years and non-complicated/non-perforated AA. Due to the small number of studies and patients included in each subgroup, these subgroup analyses need to be interpreted with caution. However, none of the levels of PLT (SMD - 0.13; 95% CI - 0.28-0.012; P = 0.071) or PDW (SMD 0.30; 95% CI - 0.22-0.83; P = 0.257) was seen decrease or increase in subjects with AA. This meta-analysis indicates a significant decrease in MPV levels in patients with AA, which makes MPV have the potential of serving as a biomarker for AA. The associations of other PLT indices with AA need to be further examined.

Abstract
OBJECTIVE Abdominal examination findings in pediatric acute appendicitis (AA) significantly vary by age. Therefore, grading systems have been developed for diagnosing pediatric appendicitis, and laboratory and radiological findings have an important role in this diagnosis. However, there is a need to develop new parameters for diagnosing AA. This study aimed to investigate the diagnostic value of platelet indices in AA. METHODS This retrospective, observational study included 207 pediatric patients who were admitted to the Emergency Department and operated on for AA. The patients were divided into three groups on the basis of their surgical and histopathological findings (non-AA, uncomplicated AA, and complicated AA). RESULTS There was no significant difference in the mean platelet volume/platelet count (MPV/PC) ratio among the groups. The white blood cell (WBC) count and the MPV/PC ratio showed a significant negative relationship (r = -0.239). The specificity for MPV was 61.8% and the sensitivity was 68.8%. Receiver operating curve analysis of WBC and MPV showed significance for diagnosing AA. CONCLUSION There is a negative, but weak, relationship between the WBC count and the MPV/PC ratio. However, the MPV/PC ratio could be a useful parameter for diagnosing pediatric AA according to receiver operating curve analysis.

Abstract
Background Several efforts have been made to find out a valuable marker to assist the diagnosis and differentiation of gangrenous/perforated appendicitis. We aimed to determine the diagnostic capacity of soluble B7H3 (sB7H3) in acute appendicitis (AA) and its accuracy as a predictor of the severity of appendicitis. Methods 182 children were allocated into four groups as follows: control group (CG, 90), simple appendicitis (SA, 12), purulent appendicitis (PA, 49), and gangrenous appendicitis (GA, 31). Prior to appendectomy, blood was collected and sent for analysis of routine examination and cytokines (sB7H3 and TNF-α). We compared values of all measured parameters according to histological findings. Furthermore, we assigned AA patients into the nonperforated appendicitis group and the perforated appendicitis group. The diagnostic effects of significant markers were assessed by ROC curves. Results Only the levels of CRP, FIB, and sB7H3 had a remarkable rising trend in AA-based groups, while differences in the levels of CRP and FIB between simple appendicitis and purulent appendicitis were not statistically significant. In addition, sB7H3 was found as the only marker in children with AA, which was markedly associated with the degree of histological findings of the appendix. Furthermore, sB7H3 had a high diagnostic value in predicting AA and complex appendicitis (PA+GA) in children. However, the diagnostic performance of sB7H3 for distinguishing PA from GA was not remarkable. Additionally, only the levels of CRP and sB7H3 were statistically different between the nonperforated appendicitis group and the perforated appendicitis group. The diagnostic performance of CRP and sB7H3 could not merely predict perforation of AA in children; however, the diagnostic performance was improved after combination. Conclusions sB7H3 could be used as a valuable marker to predict the presence of AA and complex AA in children. However, the diagnostic value of sB7H3 to predict gangrenous/perforated appendicitis was not found to be remarkable. The combination of sB7H3 and CRP might improve the prediction of perforated appendicitis.

Abstract
Background Although several previous studies have examined the association between the platelet to lymphocyte ratio (PLR) and acute appendicitis (AA), findings have been controversial. We aimed to systematically assess the available evidence to elucidate the overall relationship between the PLR and AA. Methods Pubmed and Embase databases were searched for all available published literature before August, 2019 by two independent investigators for observational studies reporting the association between the PLR and AA. Random effects models were applied for all meta-analyses. Pooled standardized mean difference (SMD) and 95% confidence interval (CI) were calculated as effect estimates. Results Eleven articles met the inclusion criteria and included in this study. Meta-analysis showed that the level of PLR in the AA group was significantly higher than that in the control group (SMD: 1.19, 95% CI: 0.75 to 1.62, P<0.001). A series of subgroup analyses were conducted to investigate the heterogeneity, showing a significant increase in PLV levels in adults with age ≥30 years (SMD: 1.46, 95% CI: 0.89 to 2.02),compared to those in adult <30 years(SMD: 0.58, 95% CI: 0.12 to 1.04) or in children (SMD: 1.03, 95% CI: 0.51 to 1.56). Compared to non-AA controls, a significant increased PLR level was also observed in non-perforated AA (SMD: 1.23, 95% CI: 0.88 to 1.59) and in AA patients during pregnancy (SMD: 0.70, 95% CI: 0.36 to 1.04), while not in perforated AA (SMD: 2.28, 95% CI: -1.72 to 6.28). Conclusions A significant increase in PLR level is found in patients with AA, indicating that PLR is a promising biomarker for AA. PLR provides a convenient option for emergency department to quickly screen for clinically or radiologically confirmed AA awaiting appendectomy, especially for pregnant women suspected of having AA. More high-quality evidence is needed to further confirm the diagnostic accuracy of PLR for AA.

Abstract
Background: Acute appendicitis (AA) is one of the most common causes of abdominal pain requiring surgical intervention. Approximately 20% of AA cases are characterized by complications such as gangrene, abscesses, perforation, or diffuse peritonitis, which increase patients' morbidity and mortality. Diagnosis of AA can be difficult, and evaluation of clinical signs, laboratory index and imaging should be part of the management of patients with suspicion of AA.Methods: This consensus statement was written in relation to the most recent evidence for diagnosis and treatment of AA, performing a literature review on the most largely adopted scientific sources. The members of the SPIGC (Italian Polispecialistic Society of Young Surgeons) worked jointly to draft it. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Chest Physicians (CHEST) for the strength of the recommendations.Results: Fever and migratory pain tend to be present in patients with suspicion of AA. Laboratory and radiological examinations are commonly employed in the clinical practice, but today also scoring systems based on clinical signs and laboratory data have slowly been adopted for diagnostic purpose. The clinical presentation of AA in children, pregnant and elderly patients can be unusual, leading to more difficult and delayed diagnosis. Surgery is the best option in case of complicated AA, whereas it is not mandatory in case of uncomplicated AA. Laparoscopic surgical treatment is feasible and recommended. Postoperative antibiotic treatment is recommended only in patients with complicated AA.

Abstract
Acute appendicitis is one of the most common causes of acute abdominal diseases seen between the ages of 10 and 19, mostly seen in males. The lifetime risk of developing acute appendicitis is 8.6% for males and 6.7% for females. We aimed to investigate the efficacy of the complete blood count parameters, C-reactive protein, and Lymphocyte-C-reactive Protein Ratio laboratory tests in the diagnosis of acute appendicitis, as well as their relationship with appendix diameter. We retrospectively examined all patients who underwent appendectomy between 1 January 2012 and 30 June 2019 in the General Surgery Clinic of Gaziosmanpasa University Faculty of Medicine. Laboratory tests, imaging findings, age, and gender were recorded. Lymphoid hyperplasia is considered as normal appendix—in other words, as negative appendicitis. The distribution of Lymphoid hyperplasia and appendicitis rates were statistically different in the groups formed according to appendix diameter (≤6 and >6 mm) (p < 0.001). We found a significant correlation between appendix diameter and WBC (White blood count), Lymphocyte, Neutrophil, RDW(Red blood cell distribution width), NLR(Neutrophil to lymphocyte ratio), and PLT/L (Platelet to lymphocyte ratio), MPV (Mean platelet volume) and RDW were significantly different in patients with an appendix diameter of ≤6 mm (p = 0.007, p = 0.006, respectively). WBC, Neutrophil, PDW, and NLR values were significantly different between appendicitis and hyperplasia groups in patients with an appendix diameter of >6 mm. The sensitivity of the NLR score (cutoff = 2.6057) in the diagnosis of appendicitis was 86.1% and selectivity was 50% in these patients. Complete blood count parameters evaluation with the clinical findings revealed that NLR is an important parameter that may help the diagnosis of acute appendicitis with an appendix diameter of >6 mm. In patients whose pathological results indicated acute appendicitis but who had a diameter of ≤6 mm, we found an elevated MPV and low RDW values.

Abstract
Introduction: Acute appendicitis is the most common cause of the abdominal pain in surgery. Despite its significant prevalence, the diagnosis is associated with many problems in some cases, which leads to false appendectomy. Objective: The aim of this study was to determine the validity of diagnostic tests of mean platelet volume (MPV) and red cell distribution width (RDW), as a new possible tool in the diagnosis of acute appendicitis. Methods: In this study, all patients who referred to the emergency department of Besat Hospital, Hamadan, Iran, in 2015, with abdominal pain and first impression of acute appendicitis, undergone appendectomy, were evaluated. The diagnostic markers of pre-operative and post-operative pathology and the validity of MPV and RDW were determined in diagnosis of acute appendicitis. Results: Laboratory and clinical data from 438 patients, presenting the signs and symptoms of acute appendicitis with the mean age of 26.51±13.9 years, were examined (55.6% men). The sensitivity, specificity, positive and negative predictive value of MPV in the diagnosis of acute appendicitis were 59.77, 98.66, 99.5 and 34.26 percent, and for the RDW were 57.79, 56.00, 86.07 and 21.98 percent, respectively. The area under the receiver operating characteristic (ROC) curve for RDW and MPV was 0.61and 0.90, respectively. The mean of MPV in patients with normal pathologic outcome was 9.52±1.60 and in patients with acute appendicitis was 7.51±1.22. There was a significant difference between the mean MPV in both groups (p<0.001). The mean of RDW in patients with normal pathology were 13.42±1.97 and 13.05±1.09, in patients with acute appendicitis. There was a significant difference between the mean RDW of the two groups (p=0.009). Conclusion: MPV and RDW indexes have the potential to be used by the surgeons in diagnosis of acute and perforated appendicitis, especially in adults, in order to reduce unnecessary appendectomy, but MPV is more valid in screening acute appendicitis, compared to the RDW.

Abstract
BACKGROUND: The occurrence and early management of acute appendicitis among children are especially important due to the difficult diagnosis and nonspecific symptoms of the disease. Diagnosis of appendicitis in children is very difficult due to similarity of its symptoms to other diseases, and also its self-limiting nature Platelet indexes such as mean platelet volume (MPV) and platelet distribution width (PDW) have been suggested as a biomarker of inflammation. AIM: Therefore, we examined the association of MPV and PDW with acute appendicitis in children. METHODS: This cross-sectional study was conducted on 464 patients with suspected acute appendicitis under the age of 18 years referred to the specialised hospitals of the ten studied provinces between October 2014 and October 2015. All data obtained regarding patient’s lab tests, i.e. platelet count, MPV and PDW and also radiological studies and surgical reports were gathered in datasheets and analysed to evaluate the potential association of platelet levels, mean platelet volume (MPV) and platelet distribution width (PDW) with acute appendicitis RESULTS: Our results showed that the MPV was significantly higher in acute appendicitis in comparison to perforated appendicitis as well as acute gangrenous appendicitis. PDW was significantly higher in acute appendicitis in comparison to perforated appendicitis and acute gangrenous appendicitis. The current project indicated that PDW < 10.05 had a sensitivity of 35% and specificity of 75%, platelet count < 229500 had a sensitivity of 24% and specificity of 75% and MPV < 8.95 had a sensitivity of 70% and specificity of 71%. CONCLUSION: Our study suggested that platelet indexes such as MPV and PDW could significantly correlate with acute appendicitis in pediatric patients. Hence, we believe that both MPV and PDW could use as a simple and low-cost lab test for diagnosing acute appendicitis. Also, this study revealed that the MPV lower than 8.95 could be a novel index for diagnosing acute appendicitis with sensitivity of 70% and specificity of 71%.

Abstract
BACKGROUND To evaluate the prognostic significance of systemic inflammation score (SIS) for patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy for non-small-cell lung cancers (NSCLCs). Methods: This retrospective cohort study was conducted on the prospectively maintained database in our institution during the study period. Preoperative SIS comprising serum albumin (sALB) and lymphocyte-to-monocyte ratio (LMR) was graded into 0, 1 and 2. Survival analysis was performed to distinguish differences in postoperative survival between three groups of SIS. Finally, multivariate Cox proportional hazards regression analyses were conducted to determine independent prognostic factors. Results: There were 390 patients with operable NSCLCs included. We applied sALB at 40 g/L and our median LMR at 3.91 as the cutoffs for modified SIS scoring criteria. Both overall survival (OS) and disease-free survival (DFS) were significantly shortened in a step-wise fashion with each 1-point increase in SIS (Log-rank p < .001). There was a significant step-wise decline in both OS and DFS rates in proportion to SIS (p < .001). No difference was found in postoperative complications between three groups of SIS. Multivariate analyses finally demonstrated that both SIS = 1 and SIS = 2 could be independent prognostic factors for unfavorable OS and DFS of NSCLCs. Conclusions: SIS can serve as a novel risk stratification tool to refine the prognostic prediction for surgical NSCLCs.

Abstract
PURPOSE OF REVIEW Concern regarding appendicitis is a common reason for presentation to the paediatric emergency department. We review recent progress in the use of biomarkers, imaging and clinical scoring systems in improving diagnostic accuracy in suspected appendicitis in children. RECENT FINDINGS Use of ultrasound, often performed at the bedside, is becoming more widespread with a parallel reduction in computed tomography (CT) use. Protocols for image acquisition and interpretation have been shown to improve diagnostic accuracy. Novel biomarkers have been explored and clinical diagnostic algorithms refined but none have achieved the level of diagnostic accuracy required. SUMMARY Appendicitis remains a clinical diagnosis. Point of care ultrasound is increasingly available and offers higher diagnostic accuracy than several routinely performed laboratory investigations. Recent publications provide support for increased use of clinician performed ultrasound, increased use of MRI, less use of CT, less emphasis on basic laboratory investigation and a renewed respect for the value of serial examination, particularly early in the course of illness.

Abstract
OBJECTIVES to investigate whether Neutrophil-to-lymphocyte ratio (NLR) can predict acute appendicitis and whether it can distinguish between uncomplicated and complicated appendicitis. METHODS A search of electronic information sources was conducted to identify all studies reporting NLR in patients with clinical suspicion or confirmed diagnosis of acute appendicitis. We considered two comparisons:1) appendicitis versus no appendicitis; 2) uncomplicated appendicitis versus complicated appendicitis. ROC curve analysis was performed to determine cut-off values of NLR for appendicitis and complicated appendicitis. RESULTS Seventeen studies, enrolling 8,914 patients were included. NLR of 4.7 was cut-off value for appendicitis with sensitivity of 88.89% and specificity of 90.91% with AUC of 0.96. NLR of 8.8 was cut-off value for complicated appendicitis with sensitivity of 76.92% and specificity 100% with AUC of 0.91. NLR >4.7 was predictor of acute appendicitis (OR:128,P < 0.0001) and, NLR >8.8 was predictor of complicated appendicitis (OR:43,P < 0.0001). CONCLUSIONS NLR predicts both diagnosis and severity of appendicitis. This may have implications for prioritising cases for surgery, for monitoring conservatively treated patients and for patients who do not routinely undergo CT scan (pregnant or paediatric patients).

Abstract
Objectives: Our aim was to study whether laparoscopic appendectomy radix ligation techniques were eutrophic in the development of intra-abdominal abscess. Methods: Between September 2009 and April 2017, all emergency cases admitted to our surgery polyclinic were reviewed, and the results of the patients who underwent laparoscopic appendectomy were collected. Appendectomy radix ligation techniques were reviewed from surgical notes on discharge reports. Postoperative controls were also reviewed, and any cases with abscess formation were reported. Results: A total of 350 patients were included in the study. Of these cases, 207 were males, and 143 were females. The mean age of the patients was 26.89±4.9 years. One hundred eighty-nine cases were found to have two endoloops placed on top of each other, whereas 161 cases had a 2 mm distance left in between the two endoloops and tied. None of the 189 cases who had endoloops placed on top of each other developed abscess formation. However, of the 161 cases who had endoloops with a 2 mm distance in between, 8 reported with abscess formation in the inner abdomen. Of these eight cases, seven had percutaneous abscess drainage by an interventional radiologist, whereas one was treated with relaparoscopy. Conclusion: In the present study, patients who had endoloops placed on top of each other developed no abscess formation, whereas in the literature’s gold standard procedure, those with a 2 mm distance left between two endoloops developed an inner abdominal abscess formation in 8 (4.9%) of the patients. We believe that this 2 mm dead space distance left between the two endoloops contributes to the formation of the abscess.
