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.

[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.

Abstract
Retroperitoneal appendiceal perforation presents unique challenges in surgical management due to the complex nature of the retroperitoneal space. We present a case of a 57-year-old male with retroperitoneal appendiceal perforation, characterized by the presence of a large amount of gas in the retroperitoneal space. Emergent laparoscopic surgery was performed to address the retroperitoneal involvement. In retroperitoneal appendiceal perforation, surgical intervention and postoperative drainage are of great significance to prevent septic shock. The interconnectedness of the retroperitoneal space with other body regions is highlighted, underscoring the potential for severe complications. This case emphasizes the need for a tailored approach to managing retroperitoneal appendiceal perforation, preventing potential complications associated with this condition.

Khalid SY, Elamin A. The Diagnostic Accuracy of Hyperbilirubinemia in Predicting Appendicitis and Appendiceal Perforation. Cureus 2023; 15:e48203. [PMID: 37929270 PMCID: PMC10624947 DOI: 10.7759/cureus.48203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/03/2023] [Indexed: 11/07/2023] Open
Abstract
Background Every diagnostic tool that may assist in the identification of appendicitis is of great importance to emergency general surgeons. While recent research has indicated that hyperbilirubinemia can serve as a valuable predictor of appendiceal perforation, these studies have not specifically examined the role of bilirubin as an indicator for acute appendicitis. This study aimed to assess the role of hyperbilirubinemia as a diagnostic factor in detecting appendicitis and appendiceal perforation. Methodology This single-center retrospective study involved 333 patients with acute appendicitis who underwent an emergency appendectomy at a model three hospital between January 2021 and December 2022. Statistical analysis was performed using STATA/SE 18.0 for Windows (StataCorp., College Station, TX, USA) to compare bilirubin levels, white blood cell count (WCC), and C-reactive protein (CRP) among normal appendices, non-perforated appendicitis, and perforated appendicitis. Results Among 333 patients, 60.66% were male, and 39.34% were female, with a male-to-female ratio of 1.54:1. The average hospital stay was 3.27 ± 3.02 days. Hyperbilirubinemia was observed in 25.53% (85 individuals). Among the 51 cases of perforated appendicitis, 70.59% had elevated bilirubin levels of above 20 μmol/L. Significantly more patients with appendiceal perforation had hyperbilirubinemia than non-perforated appendicitis (70.59% vs. 19.03%, p < 0.001). Bilirubin had higher specificity (94.29%) for detecting non-perforated appendicitis than normal appendices (odds ratio = 3.88), while WCC and CRP showed higher sensitivities. WCC had a sensitivity of 73.28% and a specificity of 42.86%, and CRP had a sensitivity of 76.53% and a specificity of 60.00%. When comparing perforated appendicitis with non-perforated appendicitis, bilirubin showed a specificity of 80.97% and an odds ratio of 10.21. The likelihood of a patient with hyperbilirubinemia having perforated appendicitis was more than 10 times higher than those without appendiceal perforation, suggesting it to be a potential indicator for appendiceal perforation. WCC showed a specificity of 26.72% and an odds ratio of 4.28, while CRP had a specificity of 23.48% and an odds ratio of 4.91. Conclusions The significant association between bilirubin levels and appendicitis highlights its potential as a valuable marker for predicting appendicitis and appendiceal perforation. The simplicity, cost-effectiveness, and diagnostic value of bilirubin assessment support its routine use in suspected cases of acute appendicitis.

Abstract
OBJECTIVE Investigate the potential use of the neutrophil-to-lymphocyte ratio (NLR) in the identification and differentiation of acute appendicitis patients, specifically between simple and complicated presentations. METHODS An observational retrospective cohort study was conducted in Aseer Central Hospital, Saudi Arabia. RESULTS In total, 103 patients were included in this study, in which males (50.5%) were more common than females (49.5%), and the most common age group was found to be 36-45 years (56.3%), followed by 18-25 years (23.3%). All patients (100%) had a diagnosis of acute appendicitis. The means of neutrophils, lymphocytes, and NLR were found to be 68.970%, 22.067%, and 5.020, respectively. The majority (69%) had non-complicated appendicitis, while (31%) had complications. A significant association was seen between NLR and the occurrence of complications (p-value = 0.00001). CONCLUSION This study can comprehensively support the evidence presented in the literature review. The use of the NLR demonstrates a notable level of accuracy in diagnosing acute appendicitis and differentiating between complex and uncomplicated cases.

Abstract
Aims The objectives of the study were to establish the function of bilirubin as a novel diagnostic tool for predicting complex appendicitis and to compare the impact of other variables such as white blood cell count (WCC), C-reactive protein (CRP), and neutrophil. Methods This retrospective, single-center cohort analysis included all patients admitted to Torbay General Hospital in Torquay, United Kingdom, between January 2020 and December 2020 with a clinical diagnosis of acute appendicitis. In addition to serum CRP, WCC, and neutrophil, serum bilirubin and other liver enzymes were obtained from the patients’ blood on admission. Results The quantitative analysis included 174 patients from the group that remained. The large majority of the sample consisted of adults and males (77% and 51.7%, respectively). Overall, 49.4% of participants in the study were diagnosed with complicated appendicitis; 74.7% of adults had complicated appendicitis, with 58.6% being male. In 68.6% of cases, perforated appendicitis was the most prevalent form of complicated appendicitis. Patients with complicated appendicitis had significantly higher WCC, neutrophil, and CRP levels than those with uncomplicated appendicitis (14.15 vs. 12.88, p = 0.016; 11.63 vs. 10.19, p = 0.007; and (89.28 vs. 40.65, p = 0.0001, respectively).. The significantly greater alkaline phosphatase and total serum bilirubin discrepancies were observed in patients with complicated appendicitis. There were statistically significant differences in the means of the patients: (18.46 vs. 10.98, p = 0.0001 and 110.64 vs. 102.24, p = 0.033). Conclusion Serum bilirubin is a crucial diagnostic aid for determining the existence of complicated appendicitis.

Abstract
Introduction The ability to predict risk of perforation in acute appendicitis (AA) could direct timely management and reduce morbidity. Platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) are surrogate severity markers in infections. This study investigates the use of PLR and NLR as a marker for distinguishing uncomplicated (UA) and complicated appendicitis (CA) in children. Materials and methods This retrospective single-center study collected data between January 1, 2014, and December 31, 2020. Children between five and 17 years of age with histologically confirmed appendicitis were included. Cut-off values for NLR and PLR were determined by employing the receiver operating characteristic (ROC) curve with sensitivity and specificity in addition to regression analysis. Results A total of 701 patients were included with a median age of 13 years. Out of which 52% of the cohort was female. The difference between the NLR and PLR ratios between UA and CA was significant (p=0.05, Kruskal-Wallis). For UA, the area under the ROC curve (AUC) and cut-off for NLR and PLR were 0.741, 3.80 with 95% CI of 0.701-0.781 and 0.660, 149.25 with 95% CI of 0.618-0.703, respectively. In CA, using NLR and PLR, AUC and cut-off were 0.776, 8.86 with 95%CI of 0.730-0.822 and 0.694, 193.67 with 95%CI of 0.634-0.755, respectively. All were significant with p<0.001. Conclusions NLR and PLR are reliable, synergistic markers predicting complicated appendicitis which can guide non-operative management in children.

Abstract
Introduction Acute appendicitis of the subhepatic appendix is uncommon, and a preoperative diagnosis is difficult without a thorough understanding of the various anatomical locations. Cross-sectional imaging is indispensable for prompt diagnosis and subsequent treatment. Surgery is the standard treatment for perforated appendicitis in the subhepatic region. In this study, we present a case of subhepatic appendicitis with an unusual presentation. Case presentation A 28-year-old man presented to our emergency department with a 3-day history of diffuse right abdominal discomfort, diarrhea, fever, and vomiting. Physical examination revealed rebound soreness and guarding in the right upper and lower quadrants. Laboratory tests revealed high levels of C-reactive protein and serum bilirubin and neutrophilic leukocytosis. Abdominal computed tomography revealed an undescended cecum and a subhepatic appendix with an intraluminal appendicolith, fat stranding, and peri-appendiceal fluid. The patient underwent open exploration and appendicectomy, during which the subhepatic perforated appendix was excised. The patient's recovery was uneventful. Discussion Atypical presentations may indicate an unusual anatomical placement of the appendix. Preoperative diagnosis using cross-sectional computed tomography imaging and a thorough understanding of these situations frequently result in early diagnosis and expeditious surgical care. Conclusion Surgical crises resulting from aberrant anatomical variations of the appendix constitute a distinct diagnostic challenge. A strong index of suspicion for this uncommon presentation permits early surgical intervention and prevents delay-induced morbidity/mortality. Appendicitis classically presents with right iliac fossa pain. Anomalous positions of the appendix can give rise to clinical challenges. Perforation in subhepatic appendicitis masquerades as acute cholecystitis. Undescended cecum could give rise to the rare anatomical position of the appendix.

Abstract
Abstract
We present two patients with right lower quadrant pain during the 36th week of pregnancy. In both cases, the challenges in diagnosing acute appendicitis in late pregnancy is underlined by misleading imaging results, revealing fluid in the lower abdomen, suggesting an appendicitis. Surgery was performed. Pre- and intraoperative gynecological examinations showed no signs of fetal distress. In patient 1, surgery revealed a torsion and necrosis of the right ovary and a 7-cm cyst of the fallopian tube. Open ovariectomy and appendectomy were performed. In patient 2, we saw a perforated appendicitis and cloudy ascites. Histology after appendectomy showed spots of endometriosis and serositis infiltrating into the appendix with signs of perforation at the tip. Patient 1 recovered after a short period of bowel paralysis. Patient 2 needed Caesarean section due to severe deceleration in the cardiotocograph and irregular uterine contractions. The newborn was kept in the neonatal ICU for 10 days.

Abstract
OBJECTIVES Complicated appendicitis needs an aggressive and urgent management, hence there is need of an efficient scoring system for predicting complicated appendicitis. With this in mind, the author developed the present scoring system for predicting complicated acute appendicitis. The study aimed to assess the suitability of this novel (Shabir's SMART-LAB) score for predicting diagnosis of complicated appendicitis. MATERIAL AND METHODS In this prospective study, a novel score designated as "SMART-LAB" SCORE, proposed by the author (Shabir) based on his previous observations was calculated in all patients. This score includes sonography (S), migratory right iliac fossa pain (M), anorexia (A), rebound tenderness (R), tenderness (T), leukocytosis (L), Acute phase protein-CRP (A), and serum bilirubin (B). RESULTS Of a total of 150 patients included in this study, 52 cases turned out to be perforated and/or gangrenous appendicitis on intraoperative/histopathologic examination. The most commonly affected age group was 10-19 years. SMART-LAB score of >9 was present in significantly higher number of patients in complicated (perforated and gangrenous) appendicitis than uncomplicated appendicitis (p value<0.001 i.e., highly significant). Hence, high likelihood of complicated appendicitis is reflected by a score >9 (with a sensitivity= 80.7%, specificity= 92.9%, PPV= 85.7%, NPV= 90.1%, and accuracy= 88.7%), while a score 7-9 needs further confirmation to reach a conclusion, and for a score of <7, there is low likelihood of complicated appendicitis. CONCLUSION It seems that this novel score (Shabir's SMART-LAB score) is a reasonably good tool to predict the diagnosis of complicated appendicitis. Early diagnosis of appendiceal perforation is important to limit the associated abdominal sepsis.

Abstract
BACKGROUND Acute appendicitis is a common surgical emergency amongst the paediatric population. Available diagnostic tools are focussed to make a diagnosis of acute appendicitis. A definitive predictive factor for the diagnosis of complicated appendicitis is lacking. Thus, this aims to analyse hyperbilirubinaemia as a predictor of complicated appendicitis amongst the paediatric population. MATERIALS AND METHODS A prospective observational study was conducted in a tertiary hospital from November 2018 to October 2019. All children undergoing emergency appendectomy were included in the study. Preoperatively, patients were evaluated clinically, and routine investigations including total and direct serum bilirubin were sent. All patients were grouped as 'simple appendicitis' or 'complicated appendicitis' based on intra-operative and histological findings. Bilirubin level was compared between these groups and analysed. RESULTS A total of 52 children fulfilling the inclusion criteria were included. The mean age was 13.2 ± 4.2 years, and the male: female ratio was 2.1:1. Thirty-four (65.4%) had simple appendicitis and 18 (34.6%) had complicated appendicitis. Total bilirubin was 23.83 ± 5.94 mmol/L in the complicated appendicitis group and 13.15 ± 3.29 mmol/L in the simple appendicitis group. Direct bilirubin was 5.28 ± 2.22 mmol/L in complicated appendicitis and 2.62 ± 0.83 mmol/L in simple one. Both total and direct bilirubin were significantly high in the complicated group (P < 0.001) compared to the simple appendicitis group. On the Receiver operating curve (ROC), the best cutoff value for total and direct bilirubin was 21 and 5.5 mmol/L, respectively. The sensitivity and specificity of total and direct bilirubin were 72.2%, 100%, and 61.1%, and 85.3%, respectively. CONCLUSION It is concluded that hyperbilirubinaemia is a good predictor for paediatric complicated appendicitis.

Abstract
Preoperative differentiation of complicated and uncomplicated appendicitis is challenging. The research goal was to construct a new intelligent diagnostic rule that is accurate, fast, noninvasive, and cost-effective, distinguishing between complicated and uncomplicated appendicitis. Overall, 298 patients with acute appendicitis from the Wenzhou Central Hospital were recruited, and information on their demographic characteristics, clinical findings, and laboratory data was retrospectively reviewed and applied in this study. First, the most significant variables, including C-reactive protein (CRP), heart rate, body temperature, and neutrophils discriminating complicated from uncomplicated appendicitis, were identified using random forest analysis. Second, an improved grasshopper optimization algorithm-based support vector machine was used to construct the diagnostic model to discriminate complicated appendicitis (CAP) from uncomplicated appendicitis (UAP). The resultant optimal model can produce an average of 83.56% accuracy, 81.71% sensitivity, 85.33% specificity, and 0.6732 Matthews correlation coefficients. Based on existing routinely available markers, the proposed intelligent diagnosis model is highly reliable. Thus, the model can potentially be used to assist doctors in making correct clinical decisions.

Abstract
Introduction Acute appendicitis (AA) is one of the most common acute general surgical presentations affecting 7% of the population at some point in their lifetime. The ability to assess the risk of complicated appendicitis (CA) from uncomplicated appendicitis (UA) in acute appendicitis (AA) could reduce the associated morbidity and mortality. The value of platelet lymphocyte ratio (PLR) as an inflammatory marker increases when its fluctuations are interpreted along with other complementary hematologic indices, such as neutrophil-to-lymphocyte ratio (NLR), which provides additional information about the disease activity. Hence, we postulated that NLR and/or PLR could serve as a potential surrogate marker in assessing the severity of AA. Aim This study aims to investigate the use of PLR and/or NLR as a surrogate biomarker in differentiating uncomplicated from complicated appendicitis. Material and methods This retrospective study was conducted at Russells Hall Hospital from January 1, 2017, to December 31, 2020. Data of all patients over age 16 years that had histologically confirmed appendicitis were retrieved. NLR and PLR were calculated from the admission hemogram, and the ratios were compared between uncomplicated (UA) or complicated appendicitis (CA). Cut-off values were calculated using the summarized ROC curve; in addition, the sensitivity and specificity with 95% confidence intervals were determined using SPSS 25.0 (IBM Corp., Armonk, NY). Results A total of 799 patients were analyzed, of which 469 (58.7%) were female. The median age was 31.2 years. The difference between NLR and PLR within the two appendicitis groups was significant (P=0.05; Kruskal-Wallis). Cohen’s kappa (degree of inter-rater agreement) between NLR and PLR showed a moderate agreement of 0.589 (P<0.001). We equally demonstrated an exponential relationship between PLR and NLR (R2 =0.510, P<0.05). For UA, the area under the curve (AUC) and the cut-off for NLR and PLR were 0.715, 4.75 with a confidence interval (CI) of 0.678-0.653 and 0.632, 155 with a CI of 0.591-0.672, respectively. For CA, using NLR and PLR, the AUC and cut-off were 0.727, 6.96 with a CI of 0.687-0.768 and 0.653, 180.5 with a CI of 0.602-0.703, respectively; all were significant with a P of <0.001. Conclusion NLR and PLR are a reliable, less cumbersome surrogate biomarker for assessing the severity of acute appendicitis.

Abstract
Total serum bilirubin and other biochemical parameters have been associated with acute appendicitis, mainly in complicated cases. The present study aimed to evaluate the role of biochemical parameters in the diagnosis of acute appendicitis, and to further investigate the role of bilirubin as a diagnostic marker irrespective of the severity of the pathology. All recorded cases of appendicectomies in a 1-year period in a single institution were reviewed. The median values of white cell count, C-reactive protein and total serum bilirubin on admission were associated with final histology, and their respective rates of abnormal and normal values were compared between patients who were proven to have negative histology and patients who were proven to have acute appendicitis. A total of 300 patients were studied. Median total serum bilirubin, white cell count and C-reactive protein on admission were significantly associated with acute appendicitis (P<0.001). Respective rates of normal and abnormal values were significantly associated with final histology (P<0.001). Total serum bilirubin demonstrated higher specificity (0.88) but lower sensitivity (0.26) and diagnostic accuracy (0.40) for acute appendicitis. In conclusion, total serum bilirubin on admission should be considered in the diagnostic workup to confirm rather than exclude appendicitis, without focusing on subgroups of specific severity of the disease. White cell count and C-reactive protein may also contribute to the diagnostic work-up, although with limited accuracy.

Abstract
Background: This prospective cohort study aimed to investigate the association of hyperbilirubinemia with perforated appendicitis in the pediatric population. Patients and Methods: A total of 284 children in whom the diagnosis of acute appendicitis was established were included in this study. The patients were allocated in study groups in regard to operative findings. The first study group included patients who had perforated appendicitis (n = 64; 22.5%) whereas the patients in the second group had simple appendicitis (n = 220; 77.5%). Blood samples for serum bilirubin levels and acute inflammatory markers were taken before the patients underwent surgery. The primary outcome of the study was to investigate whether the level of serum bilirubin should be used to distinguish between simple and perforated appendicitis. Results: The median level of serum bilirubin in children with perforated appendicitis was 27 mcmol/L whereas the patients with simple appendicitis had lower median levels of serum bilirubin (10 μmol/L; p < 0.001). An area under the receiver operating characteristic (ROC) curve for total serum bilirubin was 0.876 (95% confidence interval [CI], 0.820-0.929) in the patients who had a perforated appendicitis. An ROC analysis showed the best sensitivity (92%) and specificity (77.3%) for a cutoff value of 15.5 mcmol/L for total serum bilirubin (p < 0.001). Hyperbilirubinemia at admission was found in 35 patients (54.7%) with complicated appendicitis and in 14 patients (6.4%) with non-perforated appendicitis (p < 0.001). The modeling of collected data by multivariable logistic regression identified serum bilirubin concentration (odss ratio [OR] = 1.12; 95% CI, 1.07-1.18; p < 0.001), serum sodium concentration (OR = 0.64; 95% CI, 0.51-0.81; p < 0.001), body temperature (OR = 2.48; 95% CI, 1.05-0.84; p < 0.001), and duration of symptoms (OR = 1.06; 95% CI, 1.02-1.09; p < 0.001) as risk factors for perforated appendicitis. Conclusion: Elevateds level of total serum bilirubin may be useful as an indicator of perforated appendicitis in children. Levels of bilirubin in serum is an inexpensive, simple, and available laboratory marker and should therefore be recommended in the initial evaluation for acute appendicitis in pediatric patients.

Safety of Laparoscopic Cholecystectomy for Acute Cholecystitis in the Elderly: A Multivariate Analysis of Risk Factors for Intra and Postoperative Complications. MEDICINA (KAUNAS, LITHUANIA) 2021; 57:230. [PMID: 33801408 PMCID: PMC8002041 DOI: 10.3390/medicina57030230] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 02/23/2021] [Accepted: 02/23/2021] [Indexed: 12/13/2022]
Abstract
Background and Objectives: This study investigates the impact of age upon the safety and outcomes of laparoscopic cholecystectomy performed for acute cholecystitis, by a multivariate approach. Materials and Methods: A 2-year retrospective study was performed on 333 patients admitted for acute cholecystitis who underwent emergency cholecystectomy. The patients included in the study group were divided into four age subgroups: A ≤49 years; B: 50-64 years; C: 65-79 years; D ≥80 years. Results: Surgery after 72 h from onset (p = 0.007), severe forms, and higher American Society of Anesthesiologists Physical Status Classification and Charlson comorbidity index scores (p < 0.001) are well correlated with older age. Both cardiovascular and surgical related complications were significantly higher in patients over 50 years (p = 0.045), which also proved to be a turning point for increasing the rate of conversion and open surgery. However, the comparative incidence did not differ significantly between patients aged from 50-64 years, 65-79 years and over 80 years (6.03%, 9.09% and 5.8%, respectively). Laparoscopic cholecystectomy (LC) was the most frequently used surgical approach in the treatment of acute cholecystitis in all age groups, with better outcomes than open cholecystectomy in terms of decreased overall and postoperative hospital stay, reduced surgery related complications, and the incidence of acute cardiovascular events in the early postoperative period (p < 0.001). Conclusions: The degree of systemic inflammation was the main factor that influenced the adverse outcome of LC in the elderly. Among comorbidities, diabetes was associated with increased surgical and systemic postoperative morbidity, while stroke and chronic renal insufficiency were correlated with a high risk of cardiovascular complications. With adequate perioperative care, the elderly has much to gain from the benefits of a minimally invasive approach, which allows a decreased rate of postoperative complications and a reduced hospital stay.

Abstract
BACKGROUND In appendicitis, elevated intra-luminal pressure and ischemic necrosis of mucosa causes tissue gangrene or perforation. This leads to cytotoxin facilitated progressive bacterial invasion or translocation into the hepatic parenchyma through portal system. This phenomenon interferes with the bilirubin excretion into the bile canaliculi. In the present study, establishment of a possible role of hyperbilirubinemia as a marker of gangrenous/perforated appendicitis has been studied. METHODS After matching the inclusion and exclusion criteria, all cases of clinically diagnosed acute appendicitis were taken for this prospective, single center, observational study. Per-operative diagnosis was confirmed by histopathological examination. RESULTS Out of 110 subjects of acute appendicitis 41 subjects (37.27%) had hyperbilirubinemia. Out of 35 subjects diagnosed as complicated appendicitis 32 subjects (91.42%) had raised total bilirubin levels, while the remaining 03 (8.58%) had normal levels. Among 75 subjects diagnosed as acute simple appendicitis 09 subjects (12%) had raised total bilirubin level, while the remaining 66 subjects (88%) had normal levels. It was Mixed Type of Hyperbilirubinemia in gangrenous/perforated appendicitis. The sensitivity of Total serum bilirubin in predicting complicated appendicitis was found 91.43% (76.942% to 98.196%), where as the specificity of this test was 88.00% (78.439% to 94.363%). positive predictive value and negative predictive value were 78.03% and 95.65% respectively. Positive likelihood ratio and negative likelihood ratio were found to be 7.619 and 0.097 respectively taking prevalence of complicated appendicitis be 31.80%. Receiver Operating Characteristic curve was obtained which shows optimal criterion at Total Bilirubin Level 1.06 mg/dl where sensitivity was 91.43% and specificity was 97.33% at 95% confidence interval with 31.8% disease prevalence. CONCLUSIONS This is to conclude that Serum bilirubin level estimation, which is a simple, cheap and easily available laboratory test, can be added to the routine investigations in clinically suspected cases of acute appendicitis for early diagnosis of complications.

Abstract
Background Serotonin-containing cells are abundantly found in the appendix. Studies have shown that acute appendicitis is likely to be characterized by altered urinary 5-hydroxyindole acetic acid (5-HIAA), an active serotonin metabolite. The aim of this study is to investigate the diagnostic potential of 5-HIAA as a biomarker for acute appendicitis. Method This cross-sectional study enrolled patients referred at the Madani Hospital, with right iliac fossa pain, suspected to having the acute appendicitis. Before the initiation of the basic treatment and surgery, urine samples were obtained from the patients. Enzyme-linked immunosorbent assay (ELISA) was used for the analysis of 5-HIAA urinary levels. The obtained data were statistically analyzed using SPSS v18. Results Of 129 patients included in the study with the mean age of 29 years, 62 (48.1%) were men and 67 (51.9%) were women. Appendectomy was performed in 96 patients, where 81 cases were that of acute appendicitis. The mean levels of 5-HIAA in acute appendicitis group and in the negative appendectomy group was not statistically significant. The sensitivity of the test was 54.3% based on 7.4 μmol/L as cut-off %-HIAA value. Conclusion Our study reports that 5-HIAA urine concentration is not a reliable diagnostic marker for the diagnosis of acute appendicitis.

Abstract
Background Improved diagnostic biomarkers are required for acute appendicitis. The circulating fibrocyte percentage (CFP) is increased in inflammatory states, but has not been studied in acute appendicitis. This study aimed to determine CFP in acute appendicitis and compare diagnostic accuracy with standard serological biomarkers. Methods A prospective cohort study was carried out between June 2015 and February 2016 at University Hospital Limerick. The CFP was determined by dual‐staining peripheral venous samples for CD45 and collagen I using fluorescence‐activated cell sorting, and correlated with histopathological diagnoses. The accuracy of CFP in determining histological acute appendicitis was characterized and compared with the white cell count, C‐reactive protein concentration, neutrophil count, lymphocyte count and neutrophil : lymphocyte ratio. Results Of 95 adults recruited, 15 were healthy individuals and 80 had suspected appendicitis at presentation. Forty‐six of these 80 patients had an appendicectomy, of whom 34 had histologically confirmed appendicitis. The CFP was statistically higher in patients with pathologically proven acute appendicitis than in healthy controls (median 6·1 (i.q.r. 1·6–11·6) versus 2·3 (0·9–3·4) per cent respectively; P = 0·008). The diagnostic accuracy of CFP, as determined using the area under the receiver operating characteristic (ROC) curve, was similar to that of standard biomarkers. In multinomial regression analysis, only raised CFP was retained as an independent prognostic determinant of acute appendicitis (odds ratio 1·57, 95 per cent c.i. 1·05 to 2·33; P = 0·027). Conclusion The CFP is increased in histologically confirmed acute appendicitis and is as accurate as standard serological biomarkers in terms of diagnosis.

Abstract
The normal physiologic changes of pregnancy complicate evaluation for sepsis and subsequent management. Previous sepsis studies have specifically excluded pregnant patients. This narrative review evaluates the presentation, scoring systems for risk stratification, diagnosis, and management of sepsis in pregnancy. Sepsis is potentially fatal, but literature for the evaluation and treatment of this condition in pregnancy is scarce. While the definition and considerations of sepsis have changed with large, randomized controlled trials, pregnancy has consistently been among the exclusion criteria. The two pregnancy-specific sepsis scoring systems, the modified obstetric early warning scoring system (MOEWS) and Sepsis in Obstetrics Score (SOS), present a number of limitations for application in the emergency department (ED) setting. Methods of generation and subsequently limited validation leave significant gaps in identification of septic pregnant patients. Management requires consideration of a variety of sources in the septic pregnant patient. The underlying physiologic nature of pregnancy also highlights the need to individualize resuscitation and critical care efforts in this unique patient population. Pregnant septic patients require specific considerations and treatment goals to provide optimal care for this particular population. Guidelines and scoring systems currently exist, but further studies are required.

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
Background Misdiagnosis of the severity of acute appendicitis may lead to perforation and can consequently result in increased morbidity and mortality. In this study, the role of hyperbilirubinemia as a predictor of perforation is assessed by performing a meta-analysis of diagnostic accuracy. Methods A systematic search of the literature published over the past 20 years was performed using the EMBASE, PubMed, Cochrane library, and Google Scholar databases. Results Low values of sensitivity, specificity, and diagnostic odds ratio (DOR) were detected: 0.21 (95% confidence interval (CI): 0.13 - 0.30, standard error (SE) = 0.43), 0.27 (95% CI: 0.15 - 0.43, SE = 0.73), and 0.10 (95% CI: 0.3 - 0.28, SE = 0.05), respectively. The positive likelihood ratio (PLR) was low (0.29 (95% CI: 0.27 - 0.91, SE = 0.76)), whereas the negative likelihood ratio (NLR) was high (2.88 (95% CI: 1.66 - 5.14, SE = 0.10)). The hierarchical summary receiver operating characteristic curve was positioned towards the lower right corner, and the area under the curve was 0.19, both indicating a low level of overall accuracy and discrimination. Compared with the PLR, the negative inverse likelihood ratio (1/LR-) indicated that a positive result has a greater impact on the odds of disease than does a negative result. Conclusions Hyperbilirubinemia alone is not a reliable tool to predict perforation. Future studies should investigate whether the combined predictive values of bilirubin, C-reactive protein (CRP), and white blood cells are a more effective diagnostic tool.

Abstract
INTRODUCTION While patients with acute uncomplicated appendicitis may be treated conservatively, those who suffer from complicated appendicitis require surgery. We describe a logistic regression equation to calculate the likelihood of acute uncomplicated appendicitis and complicated appendicitis in patients presenting to the emergency department with suspected acute appendicitis. MATERIALS AND METHODS A cohort of 895 patients who underwent appendicectomy were analysed retrospectively. Depending on the final histology, patients were divided into three groups; normal appendix, acute uncomplicated appendicitis and complicated appendicitis. Normal appendix was considered the reference category, while acute uncomplicated appendicitis and complicated appendicitis were the nominal categories. Multivariate and univariate regression models were undertaken to detect independent variables with significant odds ratio that can predict acute uncomplicated appendicitis and complicated appendicitis. Subsequently, a logistic regression equation was generated to produce the likelihood acute uncomplicated appendicitis and complicated appendicitis. RESULTS Pathological diagnosis of normal appendix, acute uncomplicated appendicitis and complicated appendicitis was identified in 188 (21%), 525 (59%) and 182 patients (20%), respectively. The odds ratio from a univariate analysis to predict complicated appendicitis for age, female gender, log2 white cell count, log2 C-reactive protein and log2 bilirubin were 1.02 (95% confidence interval, CI, 1.01, 1.04), 2.37 (95% CI 1.51, 3.70), 9.74 (95% CI 5.41, 17.5), 1.57 (95% CI 1.40, 1.74), 2.08 (95% CI 1.56, 2.76), respectively. For the same variable, similar odds ratios were demonstrated in a multivariate analysis to predict complicated appendicitis and univariate and multivariate analysis to predict acute uncomplicated appendicitis. CONCLUSIONS The likelihood of acute uncomplicated appendicitis and complicated appendicitis can be calculated by using the reported predictive equations integrated into a web application at www.appendistat.com. This will enable clinicians to determine the probability of appendicitis and the need for urgent surgery in case of complicated appendicitis.

Abstract
Background Appendicitis is one of the most common surgical emergency in general surgical practices. Early and prompt diagnosis is necessary to avoid life-threatening complications associated with it. The diagnosis is mainly clinically aided by imaging techniques. The physiological obstruction of the bile flow associated with appendicular pathology leads to hyperbilirubinemia, which can be used as a predictive factor of appendicular perforation. Method This prospective study was conducted in the department of general surgery in Madras Medical College and Rajiv Gandhi Government Hospital, Chennai, from January 2012 to November 2012. A total of 378 patients with the features of acute appendicitis or appendicular perforation admitted in the emergency surgical ward were included. Results Out of 378 of the study population, 18% had appendicular perforation and 82% had acute appendicitis. Out of 67 perforations, 60 patients have hyperbilirubinemia (90%) whereas out of 311 patients with appendicitis, only 89 (29%) of them had elevated bilirubin. Hyperbilirubinemia with a cutoff point of 0.9 mg% for appendicitis patients has a sensitivity of 89.6%, specificity of 71.4%, a positive predictive value of 27%, and a negative predictive value of 96.9%. Hyperbilirubinemia with a cutoff point of >1.3 mg% for appendicular perforation has a sensitivity of 80%, specificity of 89%, a positive predictive value of 93%, and a negative predictive value of 96%. Conclusions Hyperbilirubinemia with bilirubin levels more than 1.3 mg% are highly predictive of appendicular perforation and, hence, aid in prompt diagnosis. This can be combined with a clinical diagnosis and imaging for an accurate and precise diagnosis.

Abstract
IMPORTANCE Appendicitis is a common, potentially serious pediatric disease. An important factor in determining management strategy [whether/when to perform appendectomy, duration of antibiotic therapy/hospitalization, etc.] and predicting outcome is distinguishing whether perforation is present. OBJECTIVE The objective was to determine efficacy of commonly assessed pre-operative variables in stratifying perforation risk in children with appendicitis. DESIGN A retrospective analysis of consecutive cases was performed. SETTING The setting was a large urban hospital pediatric emergency department. PARTICIPANTS Four hundred forty-eight consecutive cases of CT [computerized tomography]-confirmed pediatric appendicitis during a 6-year period in an urban pediatric ED [emergency department]: 162 with perforation and 286 non-perforated. MAIN OUTCOME(S) AND MEASURE(S) To determine efficacy of clinical and laboratory variables with distinguishing perforation outcome in children with appendicitis. RESULTS Regression analysis identified 3 independently significant variables associated with perforation outcome - and determined their ideal threshold values: duration of symptoms>1day; ED-measured fever [body temperature >38.0 °C]; CBC WBC absolute neutrophil count >13,000/mm3. The resulting multivariate ROC [receiver operating characteristic] curve after applying these threshold values gave an AUC [area under curve] of 89% for perforation outcome [p<0.001]. Risk for perforation was additive with each additional predictive variable exceeding its threshold value, linearly increasing from 7% with no variable present to 85% when all 3 variables are present. CONCLUSIONS A pre-operative scoring system comprised of 3 commonly assessed clinical/laboratory variables is useful in stratifying perforation risk in children with appendicitis. Physicians can utilize these factors to gauge pre-operative risk for perforation in children with appendicitis, which can potentially aid in planning subsequent management strategy.

Abstract
Introduction Clinical diagnosis of acute appendicitis still remains a problem. Delays in diagnosis of acute appendicitis may cause perforation and septic peritonitis which result in increasing morbidity and mortality. The aim of this study was to determine the sensitivity, specificity and the diagnostic value of total serum bilirubin levels as a predictor of acute appendicitis. Methods In this cross-sectional study, patients who underwent appendectomy with the diagnosis of acute appendicitis from April 2012 to March 2013 at Emam Reza Hospital in Mashhad (Iran) were enrolled. Serum bilirubin-Total and Direct-, were measured. Then based on the final pathologic reports, patients were categorized into five groups of normal appendix, chronic inflammatory changes, acute appendicitis, gangrenous and/or necrotic changes, and perforated appendicitis. Independent sample t-test, ANOVA, and Chi-square test were used for data analysis by SPSS version 16. Results There were 174 patients studied, (117 male, 57 female) with a mean age of 27.15±0.7 years. All of the patients had rebound tenderness; 75.3% had nausea, 58.6% had anorexia and 21.3% had fever. The histological reports of all patients showed 76.4% acute appendicitis. Analyzing p-values for SGPT, SGOT, WBC was (p=0.903) and differential count was (p=0.959). The study showed no significant difference between the pathological groups. However, there were no significant differences in serum total bilirubin levels between the pathological groups. Total bilirubin showed sensitivity of 48% and specificity of 61% in the diagnosis of acute appendicitis. Total serum bilirubin more than 0.85 mg/dl was the cut-off value with the best performance for diagnosis of appendicitis. Conclusion Bilirubin levels are reliable, sensitive and specific to diagnosis and a prediction of complicated appendicitis.

Abstract
PURPOSE The diagnostic value of the neutrophil-to-lymphocyte count ratio (NLR) and the Appendicitis Inflammatory Response (AIR) score for identifying acute appendicitis (AA) perforation in elderly patients in the emergency department (ED) were evaluated. METHODS A total of 103 patients who were admitted for appendectomy for AA via the ED between January 2012 and December 2014 were reviewed retrospectively. Patients aged 65 and over were included. Patient age, sex, comorbidities, body temperature, clinical findings and initial laboratory results including white blood cell (WBC) count, NLR, serum levels of CRP and total bilirubin (TB) in the ED were assessed, and the AIR score was calculated. RESULTS Perforation due to AA was identified in 58 (56.3 %) elderly patients. Median WBC count, neutrophil count, CRP and TB were significantly higher in the perforated group compared to the non-perforated group (p = 0.005, p = 0.001, p = 0.004 and p = 0.012) in the ED. The NLR was significantly different in the two groups (perforated vs non-perforated group, 9.5 vs 5.1, p < 0.001). The area under the curve value of NLR was 0.755 (95 % CI 0.660-0.834), and the cutoff value was 5.6 (sensitivity 78.0 % and specificity 65.9 %). In multivariate logistic analysis, NLR > 5.6 [odds ratio (OR) 6.794, p = 0.001] was significant independent factor for AA perforation in elderly patients. The AIR score risk probability did not differ between the two groups of elderly patients (p = 0.094). Twenty-five (42.4 %) patients in the perforated group and five (11.4 %) patients in the non-perforated group were classified as high probability by the modified AIR score including the NLR value (p = 0.001). CONCLUSION We suggest that the initial NLR in the elderly patient is the most powerful predictive factor for the diagnosis of AA perforation in the ED.

Abstract
BACKGROUND Delta neutrophil index (DNI) is a new inflammatory marker and the present study aimed to evaluate the predictive value of the DNI for the presence of a perforation in elderly with acute appendicitis. METHODS This retrospective observational study was conducted on 108 consecutive elderly patients (≥65 years old) with acute appendicitis treated over a 24-month period. RESULTS Sixty-nine of the 108 patients (median, IQR: 72, 67-77 years) were allocated to the perforated appendicitis group (63.9%) and 39 to the non-perforated appendicitis group (36.1%). WBC, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and DNI were significantly higher in the perforated group. In multiple logistic regression analyses, initial DNI was the only independent marker that can significantly predict the presence of perforation in multiple regression [odds ratio 9.38, 95% confidence interval (2.51-35.00), P=.001]. Receiver operator characteristic curve analysis showed that DNI is a good predictor for the presence of appendiceal perforation at an optimal cut-off for DNI being 1.4% (sensitivity 67.7%, specificity 90.0%, AUC 0.807). CONCLUSION Clinicians can reliably differentiate acute perforated appendicitis from non-perforated appendicitis by DNI level of 1.4 or more in elderly patients.

Abstract
Background Acute appendicitis is the most common surgical emergency and can represent a challenging diagnosis, with a negative appendectomy rate as high as 20 %. This review aimed to evaluate the clinical utility of individual biomarkers in the diagnosis of appendicitis and appraise the quality of these studies. Methods A systematic review of the literature between January 2000 and September 2015 using of PubMed, OvidMedline, EMBASE and Google Scholar was conducted. Studies in which the diagnostic accuracy, statistical heterogeneity and predictive ability for severity of several biomarkers could be elicited were included. Information regarding costs and process times was retrieved from the regional laboratory. European surgeons blinded to these reviews were independently asked to rank which characteristics of biomarkers were most important in acute appendicitis to inform a cost–benefit trade-off. Sensitivity testing and the QUADAS-2 tool were used to assess the robustness of the analysis and study quality, respectively. Results Sixty-two studies met the inclusion criteria and were assessed. Traditional biomarkers (such as white cell count) were found to have a moderate diagnostic accuracy (0.75) but lower costs in the diagnosis of acute appendicitis. Conversely, novel markers (pro-calcitonin, IL 6 and urinary 5-HIAA) were found to have high process-related costs including analytical times, but improved diagnostic accuracy. QUADAS-2 analysis revealed significant potential biases in the literature. Conclusion When assessing biomarkers, an appreciation of the trade-offs between the costs and benefits of individual biomarkers is needed. Further studies should seek to investigate new biomarkers and address concerns over bias, in order to improve the diagnosis of acute appendicitis.

Abstract
Background The certainty of diagnosing acute appendicitis in patients presenting with right iliac fossa pain still remains a mystery though acute appendicitis being the commonest surgical procedure done in emergency. In acute appendicitis, serum bilirubin levels are raised due to hepatocellular damage as a result of direct insult caused by Gram-negative bacterial endotoxemia. The need for the study is to conclude whether the serum bilirubin can be considered as a new laboratory marker to aid in the diagnosis of acute appendicitis and if so, does it have the predictive capacity to warn us about appendicular perforation. Materials and methods This is a prospective study carried out at rural tertiary healthcare center and includes 213 patients clinically diagnosed as acute appendicitis. Results Out of 213 patients, raised serum bilirubin ≥1.2 mg/dl was present in 195 (91.5%) patients, out of which 194 (99.4%) patients had histopathologically inflamed appendix and this difference was statistically highly significant with p-value < 0.0001. In this study, 32 patients had perforated appendix. Out of those, 30 patients had bilirubin ≥ 4 mg/dl and 2 patients had bilirubin level between 1.2 and < 4 mg/dl. Raised serum bilirubin (≥4 mg/dl) was present in 35 (17.9%) patients, out of which 30 (87.7%) patients had perforated appendix. How to cite this article Saxena D, Tandon M, Shah Y, Gedam BS.

Abstract
OBJECTIVE To investigate the patient's history and physical examination information to find out risk factors associated with complicated appendicitis. MATERIAL AND METHODS Two hundred patients who were admitted with complicated appendicitis (including abscess, phlegmon, and generalized peritonitis) were retrieved from our database. Two hundred patients with non-complicated acute appendicitis were randomly selected from the same period. These two groups were compared in terms of demographic characteristics, past medical history, and presenting symptoms. We made a multivariate analysis model using binary logistic regression and backward stepwise elimination. RESULTS Based on multivariate analysis, risk factors for complicated appendicitis included presenting with epigastric pain (OR=3.44), diarrhea (OR=23.4) or malaise (OR=49.7), history of RLQ pain within the past 6 months (OR=4.93), older age (OR=1.04), being married (OR=2.52), lack of anorexia (OR=4.63) and longer interval between onset of symptoms and admission (OR=1.46). Conversely, higher (academic) education was associated with decreased odds for complicated appendicitis (OR=0.26). CONCLUSION Our findings suggest that a surgeon's clinical assessment is more reliable to make a judgment. "Bedside evaluation" is a useful, cheap, quick and readily available method for identifying those at risk for developing complicated acute appendicitis.

Abstract
INTRODUCTION suspected appendicitis is the most common indication for surgery in non-obstetric conditions during pregnancy and occurs in about one in 500 to one in 635 pregnancies per year. This occurs more often in the second trimester of pregnancy. Acute appendicitis is the most common general surgical problem encountered during pregnancy. METHODS a literature review on research of scientific articles, under the terms "acute appendicitis" and "pregnancy", in PubMed, Lilacs/SciELO, Scopus, Cochrane Library and Uptodate databases. RESULTS the clinical manifestations of appendicitis are similar to non-pregnant women, however, without a classic presentation, which often occurs, diagnosis is difficult and must be supported by imaging. DISCUSSION clinical diagnosis should be strongly suspected in pregnant women with classic findings such as abdominal pain that migrates to the right lower quadrant. The main purpose of imaging is to reduce delays in surgical intervention due to diagnostic uncertainty. A secondary objective is to reduce, but not eliminate, the negative appendectomy rate. Differential diagnosis of suspected acute appendicitis usually includes pathologies considered in non-pregnant people. CONCLUSION the imaging study of choice is ultrasound, MRI may be used when the former is not conclusive and, as a last resort, a CT scan can be performed. The treatment remains appendectomy by laparotomy, since the feasibility of video- assisted surgery in these cases remains controversial.

Abstract
BACKGROUND The diagnosis of acute appendicitis is made using clinical findings and investigations. Recent studies have suggested that serum bilirubin, a cheap and simple biochemical test, is a positive predictor in the diagnosis of appendiceal perforation and may be more specific than C-reactive protein (CRP) and white cell count (WCC). The aim of this study was to investigate the utility of the serum bilirubin level in patients with suspected acute but non-perforative appendicitis. METHODS A retrospective chart review of 213 patients who presented with suspected appendicitis in a 6-month period to Nambour General Hospital was performed. Serum bilirubin, WCC and CRP were recorded and analysed as to their utility in relation to the final diagnosis. RESULTS A total of 196 patients underwent an appendicectomy and 41 of these were negative. The specificity of hyperbilirubinaemia for appendicitis overall was 0.83 with a positive predictive value (PPV) of 0.86, compared with CRP (specificity 0.40, PPV 0.75) and WCC (specificity 0.67, PPV 0.85). The area under the receiver operating characteristic curve for bilirubin was 0.6289 compared to 0.6171 for CRP and 0.7219 for WCC. A subgroup analysis of those with complicated appendicitis demonstrated a PPV for bilirubin of 0.66 compared to 0.58 for WCC and 0.34 for CRP in agreement with the literature. Subgroup analysis of hyperbilirubinaemia in simple appendicitis demonstrated a PPV of 0.81 compared to CRP (0.71) and WCC (0.82). CONCLUSION Bilirubin had a higher specificity than CRP and WCC overall in patients with appendicitis. Hyperbilirubinaemia had a high PPV in patients with simple appendicitis.

Abstract
Purpose Recently, randomized controlled trials have reported that conservative therapy can be a treatment option in patients with noncomplicated appendicitis. However, preoperative diagnosis of noncomplicated appendicitis is difficult. In this study, we determined predictive factors to distinguish patients with noncomplicated appendicitis from those with complicated appendicitis. Methods A total of 351 patients who underwent surgical treatment for acute appendicitis from January 2011 to December 2012 were included in this study. We classified patients into noncomplicated or complicated appendicitis groups based on the findings of abdominal computed tomography and pathology. We performed a retrospective analysis to find factors that could be used to discriminate between noncomplicated and complicated appendicitis. Results The mean age of the patients in the complicated appendicitis group (54.5 years) was higher than that of the patients in the noncomplicated appendicitis group (40.2 years) (P < 0.001), but the male-to-female ratios were similar. In the univariate analysis, the appendicocecal junction's diameter, appendiceal maximal diameter, appendiceal wall enhancement, periappendiceal fat infiltration, ascites, abscesses, neutrophil proportion, C-reactive protein (CRP), aspartate aminotransferase, and total bilirubin were statistically significant factors. However, in the multivariate analysis, the appendiceal maximal diameter (P = 0.018; odds ratio [OR], 1.129), periappendiceal fat infiltration (P = 0.025; OR, 5.778), ascites (P = 0.038; OR, 2.902), and CRP (P < 0.001; OR, 1.368) were statistically significant. Conclusion Several factors can be used to distinguish between noncomplicated and complicated appendicitis. Using these factors, we could more accurately distinguish patients with noncomplicated appendicitis from those with complicated appendicitis.

Abstract
AIM The aim of this study is to evaluate the diagnostic value of pre-operative bilirubin levels in the diagnosis of acute appendicitis and appendiceal perforation. METHOD A retrospective analysis of 557 patients undergoing emergency appendicectomy over a 24-month period at a large teaching hospital. Hyperbilirubinaemia was defined as >25 µmol/L. Data were analysed using descriptive statistics. RESULTS 484 of the 557 (86.9 %) operated cases were found histologically to be appendicitis. 116 cases of the 484 were perforated (24 %). Bilirubin levels were significantly higher in the group with appendicitis versus the group found to have a normal appendix at histology, [median (IQR) 12.0 µmol/L (9.00) vs. 8.0 µmol/L (7.00) respectively, p < 0.001], despite being within normal serum bilirubin range. Sensitivity of hyperbilirubinaemia for acute appendicitis was only 8 %, however specificity was 94 %. PPV was 85 % and NPV was 26 %. Whilst bilirubin was higher in patients with a perforated appendix versus acute appendicitis [median (IQR) 13.0 µmol/L (9.00) vs. 11.0 µmol/L (9.00), respectively], statistically, there was no significant difference in pre-operative bilirubin levels between the perforated appendicitis cases and the non-perforated appendicitis cases (p = 0.326). However, the specificity of hyperbilirubinaemia for perforated appendicitis was 93 %, sensitivity 9.4 %, PPV 24 % and NPV 82 %. CONCLUSION Bilirubin levels may be high, but remain within normal range, in cases of appendicitis. Therefore, bilirubin levels may be a useful measurement when investigating a patient with suspected appendicitis. Hyperbilirubinaemia is highly specific with regards to perforation, a finding supported by other studies. However, possibly because of the few perforated cases in this study, we cannot recommend that hyperbilirubinaemia be used to predict perforation.

Abstract
INTRODUCTION Acute appendicitis is a common surgical diagnosis. We investigated the use of blood markers (WCC, CRP and serum bilirubin) and diagnostic imaging (USS and CT scan) to arrive at this diagnosis, as well as the surgical approach used for appendicectomy. METHODS This was a retrospective analysis of consecutive patients undergoing appendicectomy in seven hospitals within GG&C Health Board during a 6 month study period. Data were collected from electronic patient records. Sensitivity and specificity of each investigation for diagnosing acute appendicitis was calculated. RESULTS 363 patients were included. Appendicectomy was performed open in 53%, laparoscopically in 43% and converted in 4%. Diagnostic imaging was used in 38%. The overall negative appendicectomy rate was 15% (18% when no imaging was used, 23% when USS was used and 1% when CT scanning was used). Elevated bilirubin had a sensitivity of 0.44 and a specificity of 0.84 for detecting acute appendicitis. Sensitivity and specificity for elevated WCC were 0.78 and 0.55, and for elevated CRP were 0.81 and 0.59, respectively. The specificity of bilirubin for diagnosing perforated appendicitis was 0.63. DISCUSSION WCC and CRP were sensitive blood markers in acute appendicitis, whereas serum bilirubin was more specific. Diagnostic imaging with a CT scan was very effective at reducing the rate of negative appendicectomy, but USS was not. CONCLUSION Serum bilirubin has utility in diagnosing acute appendicitis, irrespective of whether perforation has occurred. CT scanning should be considered the first line imaging modality for investigation of acute appendicitis if diagnosis is in doubt.

Abstract
UNLABELLED Appendicitis is a common clinical diagnosis aided by biochemical, haematological and radiological investigations. The role of some investigations, such as bilirubin, is controversial but could indicate complicated appendicitis. Accurate diagnosis enables prioritisation of patients on operating lists and a possible reduction in unnecessary investigations. METHODS This is a retrospective cohort study of 1347 patients who underwent appendicectomy. Statistical analysis of serum bilirubin levels was performed according to histological classification of appendicitis. RESULTS Mean serum bilirubin levels; perforated/gangrenous appendicitis 20.5 mg/L (SD 12.6), inflamed appendicitis mean 17.5 mg/L (SD CI 11.1), normal appendix mean 12.6 mg/L (7.0). Kruskal-Wallis indicated bilirubin levels were significantly different (H=128.87, df=4, p<.001) between histological groups, and a post hoc analysis with Bonferroni adjustment showed perforated/gangrenous to be significantly higher than all other groups (p<.001). Binary logistic regression combining White Cell Count (WCC) level, C-Reactive Protein (CRP) and Bilirubin levels gave a sensitivity and specificity of .69 with AUROC=.766 (std error .015) for gangrenous/perforated. Assessment according to clinical relevance showed only 30.4% of patients with an abnormally raised bilirubin had gangrenous/perforated appendicitis. CONCLUSIONS Serum bilirubin does not independently predict perforation/gangrenous appendicitis. Statistical analysis showed differences in mean bilirubin between histological groups however this did not relate to clinical significance as bilirubin levels were still within normal clinical limits. Diagnosis of complicated appendicitis should be made on clinical grounds, with utilization of biochemical/haematological investigations, but there should not be independent reliance on investigations such as bilirubin.

Abstract
BACKGROUND Hyperbilirubinaemia is reported to be a positive predictor in diagnosing appendicitis and especially appendiceal perforation. We, therefore, analysed the diagnostic accuracy of serum bilirubin in anticipating appendicitis and its severity. METHODS All consecutive patients undergoing appendectomy for suspected appendicitis from May 2009 to August 2011 were analysed. Patients were classified based on final histopathological findings into the groups: no appendiceal inflammation, non-perforated appendicitis and perforated appendicitis. Primary outcome was the diagnostic accuracy of serum bilirubin levels in discriminating between no appendiceal inflammation and any appendicitis (perforated and non-perforated appendicitis) and non-perforated and perforated appendicitis. RESULTS Of 493 analysed patients, 125 (25%) had no appendiceal inflammation, 312 (64%) had non-perforated appendicitis and 56 (11%) had perforated appendicitis. The proportion of patients with bilirubin elevation (>1.1 mg/dL) was different between those with no appendiceal inflammation (14%) and any appendicitis (36%) (p<0.0001), and between non-perforated appendicitis and perforated appendicitis 48% (p=0.04). However, the positive and negative likelihood ratios (LRs) for an elevated bilirubin were poor at discriminating the groups: no appendiceal inflammation versus any appendicitis (LR+ 2.62 (95% CI 1.65 to 4.16) and LR- 0.75 (95% CI 0.67 to 0.83)) and non-perforated appendicitis versus perforated appendicitis (LR+ estimate 1.74 (95% CI 1.28 to 2.38) and LR- 0.72 (95% CI 0.55 to 0.93)). CONCLUSIONS Hyperbilirubinaemia is present in acute appendicitis but has a low diagnostic accuracy in discriminating between any appendicitis versus no appendiceal inflammation and perforated versus non-perforated appendicitis and is, therefore, of limited value in clinical routine.

Abstract
BACKGROUND Appendicitis is a frequent reason for hospital admissions. Elevated C-reactive protein, white blood cell count, and serum bilirubin have been suggested as individual markers for appendicitis and appendiceal perforation. The aim of this study was to analyze if a combination of serologic markers could increase the prognostic accuracy of diagnosing non-perforated and perforated appendicitis. MATERIAL AND METHODS Demographic data, histological findings, blood tests, and clinical symptoms were collected on all patients who underwent a diagnostic laparoscopy, a laparoscopic appendectomy, or conventional (open) appendectomy between May 2009 and May 2012 from a surgical department. The patients were grouped into those with either perforated appendicitis, non-perforated appendicitis, or differential diagnosis. Univariate and multivariate models were used to identify which markers were useful in predicting acute and perforated appendicitis, and receiving operating characteristics curves were used to find the specificity, sensitivity, and the negative and positive predictive values. RESULTS A total of 1008 patients were operated under suspicion of appendicitis. From these, 700 patients had a pathologically verified inflamed appendix and 190 had a perforated appendix. Patients with acute appendicitis had significantly higher blood levels of white blood cell, bilirubin, C-reactive protein, and alanine transaminase than patients without appendicitis. Patients with perforated appendicitis had significantly higher levels of white blood cell, bilirubin, and C-reactive protein than patients with non-perforated appendicitis. The highest positive predictive value to discriminate between acute appendicitis and non-appendicitis was of a linear regression model combining white blood cell count, bilirubin, and alanine transaminase. C-reactive protein levels and a linear regression model, including white blood cell count, bilirubin, and C-reactive protein levels as variables, had the highest negative predictive values when discriminating between perforated and non-perforated appendicitis. CONCLUSION Combining blood markers was useful in predicting appendicitis and perforated appendicitis. In addition to C-reactive protein and white cell count, blood levels of bilirubin, and alanine transaminase may be useful.

Abstract
BACKGROUND Acute abdominal complaints in children are common presentations in the emergency department. The aetiology, presentation, diagnosis and management often differ from those in adults. METHODS This review was based on expert paediatric surgical experience confirmed by evidence from the literature obtained by searching PubMed and the Cochrane Library. Keywords used were the combinations of 'abdominal emergencies', 'acute abdomen' and the disorders 'acute appendicitis', 'intussusception', 'volvulus', 'Meckel's diverticulum', 'incarcerated inguinal hernia', 'testicular torsion' and 'ovarian torsion' with 'children'. Information was included from reviews, randomized clinical trials, meta-analyses, and prospective and retrospective cohort studies. RESULTS Presentation and symptoms of abdominal emergencies, especially in young children, vary widely, which renders recognition of the underlying disorder and treatment challenging. Critically targeted imaging techniques are becoming increasingly important in obtaining the correct diagnosis without unnecessary delay. Minimally invasive techniques have become the method of choice for the diagnosis and treatment of many abdominal emergencies in children. CONCLUSION Knowledge of abdominal disorders in childhood, their specific presentation, diagnosis and treatment facilitates management of children with acute abdomen in emergency departments. Imaging and minimally invasive techniques are becoming increasingly important in the diagnosis of acute abdomen in children. Urgent operation remains the cornerstone of therapy for most acute abdominal disorders.

Abstract
PURPOSE Elevation of the serum total bilirubin (STB) level not stemming from hepatic dysfunction or biliary obstruction may be seen in cases of acute appendicitis. This paper deals with the clinical significance of such elevations. METHODS Data from 410 appendectomized patients classified into two groups (a high preoperative STB group and a normal preoperative STB group) were analyzed to reveal the significance of preoperative hyperbilirubinemia. We also examined whether the preoperative STB level might serve as a risk factor for gangrenous appendicitis by a multivariate analysis. RESULTS Gangrenous appendicitis was more common in the high preoperative STB group (p < 0.001). The multivariate analysis revealed that an elevated preoperative STB level (odds ratio 1.7919) was a risk factor for gangrenous appendicitis. CONCLUSION In patients with an elevated preoperative STB level, it is very likely that the inflammation is severe and that the disease has progressed to a severe condition histopathologically; therefore, meticulous attention should be paid to the selection of the surgical procedure, as well as to the postoperative clinical course.

Abstract
At present, the treatment of choice for uncomplicated acute appendicitis in adults continues to be surgical. The inflammation in acute appendicitis may sometimes be enclosed by the patient’s own defense mechanisms, by the formation of an inflammatory phlegmon or a circumscribed abscess. The management of these patients is controversial. Immediate appendectomy may be technically demanding. The exploration often ends up in an ileocecal resection or a right-sided hemicolectomy. Recently, the conditions for conservative management of these patients have changed due to the development of computed tomography and ultrasound, which has improved the diagnosis of enclosed inflammation and made drainage of intra-abdominal abscesses easier. New efficient antibiotics have also given new opportunities for nonsurgical treatment of complicated appendicitis. The traditional management of these patients is nonsurgical treatment followed by interval appendectomy to prevent recurrence. The need for interval appendectomy after successful nonsurgical treatment has recently been questioned because the risk of recurrence is relatively small. After successful nonsurgical treatment of an appendiceal mass, the true diagnosis is uncertain in some cases and an underlying diagnosis of cancer or Crohn’s disease may be delayed. This report aims at reviewing the treatment options of patients with enclosed appendiceal inflammation, with emphasis on the success rate of nonsurgical treatment, the need for drainage of abscesses, the risk of undetected serious disease, and the need for interval appendectomy to prevent recurrence.

Abstract
Hyperbilirubinemia associates with perforated acute appendicitis, but the precise test characteristics have not been determined by sufficiently powered studies. A systematic literature search of reports on hyperbilirubinemia in acute appendicitis was performed. After review and quality assessment of eight studies encompassing a total of 4974 patients the sensitivity, specificity and other measures of accuracy of hyperbilirubinemia as a predictor of perforation in acute appendicitis were pooled using a random-effects model. Summary estimates for hyperbilirubinemia (cutoff 1 mg/dl) as a predictor of perforation in acute appendicitis were as follows: sensitivity, 0.49 (95% confidence interval [CI], 0.45-0.52); specificity, 0.82 (95% CI, 0.80-0.83); positive likelihood ratio, 2.51 (95% CI, 1.58-4.00); negative likelihood ratio, 0.58 (95% CI, 0.44-0.76); diagnostic odds ratio was 4.42 (95% CI, 2.21-8.83). In summary receiving operating characteristic (SROC) analysis, the area under curve was 0.73. The presence of hyperbilirubinemia does not alone distinguish a perforation in acute appendicitis. Serum bilirubin level is of some value as a predictor of appendiceal perforation. Patients with hyperbilirubinemia combined with symptoms and signs consistent with severe acute appendicitis should be considered for early appendectomy.

Abstract
INTRODUCTION Inflammatory markers such as white cell count (WCC) and C-reactive protein (CRP) and, more recently, bilirubin have been used as adjuncts in the diagnosis of appendicitis. The aim of this study was to determine the diagnostic accuracy of the above markers in acute and perforated appendicitis as well as their value in excluding the condition. METHODS A retrospective analysis of 1,169 appendicectomies was performed. Patients were grouped according to histological examination of appendicectomy specimens (normal appendix = NA, acute appendicitis = AA, perforated appendicitis = PA) and preoperative laboratory test results were correlated. Receiver operating characteristic (ROC) curve area analysis (area under the curve [AUC]) was performed to examine diagnostic accuracy. RESULTS ROC analysis of all laboratory variables showed that no independent variable was diagnostic for AA. Good diagnostic accuracy was seen for AA when all variables were combined (WCC/CRP/bilirubin combined AUC: 0.8173). In PA, the median CRP level was significantly higher than that of AA (158mg/l vs 30mg, p<0.0001). CRP also showed the highest sensitivity (100%) and negative predictive value (100%) for PA. CRP had the highest diagnostic accuracy in PA (AUC: 0.9322) and this was increased when it was combined with WCC (AUC: 0.9388). Bilirubin added no diagnostic value in PA. Normal levels of WCC, CRP and bilirubin could not rule out appendicitis. CONCLUSIONS CRP provides the highest diagnostic accuracy for PA. Bilirubin did not provide any discriminatory value for AA and its complications. Normal inflammatory markers cannot exclude appendicitis, which remains a clinical diagnosis.

Abstract
BACKGROUND AND AIMS Delayed or wrong diagnosis in patients with appendicitis can result in perforation and consequently increased morbidity and mortality. Serum bilirubin may be a useful marker for appendiceal perforation. The purpose of this systematic review was to evaluate studies investigating elevated serum bilirubin as a predictor for appendiceal perforation. MATERIAL AND METHODS Medline, Embase, and Cochrane databases were searched for studies evaluating elevated bilirubin in the diagnosis of perforated appendicitis. Study selection criteria included English language papers evaluating serum bilirubin as a marker of appendiceal perforation in humans. A total of 189 abstracts were screened for eligibility, of which five clinical studies were included in this study. RESULTS Bilirubin was significantly higher in patients with appendiceal perforation compared with patients with appendicitis without perforation. Elevated serum bilirubin had a sensitivity ranging from 0.38 to 0.77 and a specificity ranging from 0.70 to 0.87 in predicting appendiceal perforation. CONCLUSIONS Elevated serum bilirubin for determining the risk of perforation in appendicitis has low sensitivity but higher specificity. This measure can therefore be used as a supplement in the diagnostic process.
