Background:Acute appendicitis is a very common surgical emergency. Early and correct diagnosis and early intervention are necessary to prevent complications. It is often diagnosed on clinical signs and a certain ratio of negative appendectomy is acceptable. For early and accurate diagnosis, various scoring systems such as Alvarado, Ohmann, Eskelinen and more recently Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) have been developed.Objective:In this study, we aimed to compare the effectiveness and accuracy of scoring systems.Materials and methods:The patients who attended emergency department and operated with acute appendicitis pre-diagnosis were evaluated retrospectively. Alvarado, Ohmann, Eskelinen, and RIPASA scores were calculated and compared with histopathologic results by reviewing the patient files.Results:A total of 76 patients (44 males and 32 females) were included in the study. The mean age was 33.8 ± 13.2 years. Of which, 59 patients (77.6%) were diagnosed to have acute appendicitis on histopathological examination. The mean leukocyte count was 13.9 ± 3.7 × 103μL. Sensitivity and specificity of Alvarado, Ohmann, Eskelinen, and RIPASA were 36%–82%; 58%–71%; 36%–8%, and 68%–71%, respectively. Cut-off values were 8, 14, 55.63, and 10, respectively. RIPASA had the highest accuracy. The cut-off value of leukocyte counts was 13,900 × 103/μL. Sensitivity and specificity were 64% and 88%, respectively; positive predictive value was 95%. In the receiver operating curve analysis, the area under the curve was found to be 74%.Conclusion:The RIPASA scoring system is a more reliable scoring system than Ohmann, Eskelinen, and Alvarado scoring systems. In cases of suspected acute appendicitis, it may be useful to evaluate patients with RIPASA score in emergency departments by general practitioners, where there is no general surgeon. Thus, patients can be guided in a timely manner to reduce the complications that may arise from delays. The cut-off value of 13,900 × 103/μL is an important marker for the presence of acute appendicitis.

Introduction: Scoring systems are still valuable and valid for differential diagnosis of acute appendicitis (AA). Bedel Score is a new diagnostic tool with 7 parameters that can be easily applied. The aim of this study is to determine the diagnostic performance of the Bedel score in AA and compare it with the Alvarado score. Methods: Our study consisted of 95 patients as a prospective cohort who were admitted to our emergency department due to abdominal pain and were hospitalized with a preliminary diagnosis of AA. Bedel and Alvarado scores were calculated. The patients were categorized into two groups (positive and negative appendectomy) according to their histopathological diagnosis. Results: The study population consisted of 65 (68.4%) male and 30 (31.6%) female patients. The mean age of the patients was 34 (18-87) years. 81 (85.3%) of the patients had histopathologically confirmed AA. Median Alvarado score was significantly higher in patients with positive AA than those with negative AA (7 (range: 3-10) vs. 5 (range 3-7), p<0.001, respectively). Median Bedel score of positive AA patients were also significantly higher than those with negative AA (9 (range: 6-10) vs. 5 (range 2-8) p<0.001, respectively) In separating acute appendicitis from negative exploration, the threshold of the Alvarado score is 63% sensitivity for ?7, 85.7% specificity; The Bedel score had 80.2% sensitivity and 92.9% specificity for the threshold value ?7. Conclusion: Bedel score is fast, simple, easy to learn and apply, as well as an effective and practical scoring system with only 7 parameters. Keywords: Acute appendicitis, Alvarado score, New score, Negative appendectomy

Background: Acute appendicitis is the most common cause of acute abdominal pain in young adults requiring emergency surgery. Appendicectomy is the most frequently performed surgery. The diagnosis is often challenging and the decision to operate in an emergency setting is always debatable. A combination of clinical signs and symptoms with laboratory findings in many scoring systems are suggesting the probability of appendicitis and the possible subsequent management pathway. The aim was to evaluate accuracy of the clinical Alvarado scoring system, radiological finding and histopathological examination for the diagnosis of acute appendicitis.Methods: A retrospective study was conducted in the department of general surgery in a tertiary care centre in South India. Total of 237 patients with acute abdominal pain were included and evaluated with the clinical Alvarado scoring system, radiological finding with (USG/CT abdomen) and histopathological examination for the diagnosis of acute appendicitis. The data was collected and analyzed retrospectively.Results: Of the 237 patients, 164 patients were male (69.1%) and rest is female. The correlation of the Alvaroda score with histopathological findings in groups with score > 7 and ≤7 the correlation of Alvarado score and the ultrasound findings were comparable between the study groups. The sensitivity of ultrasound in diagnosing acute appendicitis in patients with Alvarado score >7 was 72.99%. The sensitivity of ultrasound in diagnosing acute appendicitis in patients with Alvarado score ≤7 was decreased to 27%.Conclusions: The diagnostic accuracy of clinical features is far better than radiological investigations in the diagnosis of acute appendicitis. Therefore, it is concluded that it is better to use radiological investigations only to confirm the diagnosis of acute appendicitis rather to diagnose it.

Background: Acute appendicitis is one of the most common cause of acute abdomen surgery. Several scoring systems have been adopted by physicians to aid in the diagnosis and decrease the negative appendicectomy rate. Tzanakis scoring system is one such score. Objective of present study was the validation of this scoring system in our population and compare its accuracy with histopathological examination (HPE).Methods: A retrospective study was carried out at the Department of Surgery at Mohammad Afzal Beigh Memorial Hospital Anantnag India. Tzanakis score was calculated in 288 patients who underwent appendicectomy from September 2016-2018 and HPE results were analysed.Results: 276 patients were eligible for the study. The sensitivity and specificity of Tzanakis score in diagnosing appendicitis was 90.66% and 73.68% respectively. The overall diagnostic accuracy was 86.23% with positive predictive value of 97.89% and negative predictive value of 36.84%.Conclusions: Tzanakis scoring system is an accurate modality in establishing the diagnosis of acute appendicitis and preventing a negative laparotomy.

Introduction: Various diagnostic criteria have been described for acute appendicitis. For decades the most commonly used one has been Alvarado score. RIPASA scoring system has also been developed for Asian population which has shown highest sensitivity and diagnostic accuracy. This study aimed to compare these two diagnostic criteria in Nepalese population attending a tertiary center. Methods: Patients with clinically suspected acute appendicitis were classified according to both Alvarado and RIPASA scoring systems before undergoing surgery. Histopathological examination was taken as the gold standard for diagnosis. Statistical analysis was done using McNemar's test as applicable. Results: Ninety nine (90 %) patients had histologically confirmed appendicitis. With the cut-off value greater than 7.5 for RIPASA score; sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy and negative appendectomy rates were 94.5%, 27.27 %, 92.16 %, 37.5 %, 88.18% and 7.84% respectively. With the cut-off value greater than 7 for Alvarado score, sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy and negative appendectomy rates were 71.72%, 72.73 %, 95.95 %, 22.22%, 71.82 %, and 4.05 % respectively. 94.5% of patients were correctly stratified by RIPASA under higher probability group while only 71.8 % were classified by Alvarado (p value= 0.0001). Conclusion: RIPASA scoring system showed high sensitivity and diagnostic accuracy in comparison to Alvarado scoring system. So, this method can be applied in Nepalese setting for the diagnosis of acute appendicitis.

Our objective was to compare the diagnostic accuracy of Alvarado and appendicitis inflammatory response (AIR) scoring systems among children suspected of acute appendicitis concerning their postoperative outcomes. During a two-year period, a prospective multicentric study was carried in the selected hospitals of Iran. All children who were admitted with the diagnosis of acute appendicitis were enrolled in the study. However, patients suffering from generalized peritonitis or those who had a history of abdominal surgery were excluded. Before decision-making, each patient’s score according to two appendicitis scoring systems was calculated. The clinical outcomes and diagnosis of patients were then compared to the results of each scoring system. For those patients who were a candidate for surgery, the final diagnosis of acute appendicitis was made by histopathology. Patients were divided into a high- and low-risk group according to scoring systems outcomes. Among the patients with a low score for appendicitis, the AIR scoring system had a sensitivity and specificity of 95% and 74%, respectively, which was more promising in comparison to that of the Alvarado system (90% and 70%, respectively). Regarding the patients at higher risk of acute appendicitis, none of the scoring systems provided reliable results since both systems showed sensitivity and specificity of less than 50%, which was not sufficient to distinguish patients who are a candidate for surgery. AIR and Alvarado scoring systems are not accurate models to predict the risk of acute appendicitis among children; however, the AIR system could be used as a reliable material to rule out the acute appendicitis diagnosis.

Background.Decision-making for management may sometimes be difficult in acute appendicitis (AA). Various diagnostic scoring systems exist, but their sensitivity and specificity rates are far from ideal. In this study, the determination of the predictors and the effect of radiological data and developing a new scoring system were aimed.Methods.Medical records of patients who were hospitalized for AA between February 2012 and October 2016 were retrospectively reviewed. All data were compared between patients with and without appendicitis. The multivariate analysis was performed to define significant variables and to examine the sensitivity and specificity of each group of predictors including radiological data. A new scoring system (NSS) was formed and was compared with two existing scoring systems: pediatric appendicitis score (PAS) and Alvarado scoring system (ASS) by using reclassification method.Results.Negative appendectomy rate was 11.3%. Statistical analysis identified 21 independently significant variables. The heel drop test had the highest odds ratio. Sensitivity and specificity rates of clinical predictors were 84.6% and 94.8%, respectively. Radiological predictors increased the sensitivity rate to 86.9%. Sensitivity and specificity rates for PAS, ASS, and NSS were 86.8% and 83.9%, 84.7% and 81.6%, and 96.8% and 95.6%, respectively. The “re-assessed negative appendectomy rate” was 6.2% and false positive results were remarkably more common in patients with duration of symptoms less than 24 hours.Conclusion.Radiological data improves the accuracy of diagnosis. Containing detailed clinical and radiological data, NSS performs superiorly to PAS and ASS, regarding sensitivity and specificity without any age limitation. The efficiency of NSS may be enhanced by determining different predictors for different phases of the inflammatory process.

Background: Acute appendicitis is the most common acute surgical condition of the abdomen requiring early intervention. The diagnosis is often challenging and the decision to operate in an emergency setting is always debatable. Alvarado score for diagnosis of acute appendicitis is easy and additional tools like sonography results in accurate diagnosis. The aim was to evaluate accuracy of the clinical Alvarado scoring system, radiological findings and histopathological examination for the diagnosis of acute appendicitis.Methods: 100 cases of acute abdomen admitted in PES institute of medical sciences and research, Kuppam from December 2016 to June 2018 were included. Clinical examination was done and all patients were subjected to ultrasound abdomen examination and other relevant blood and imaging investigations.Results: Out of 100 patients 62 were males and 38 were Females. Most common symptom was pain in the right iliac fossa and patients with Alvarado Score 7 or > 7 subjected to USG followed by emergency appendectomy showed positive operative findings and histopathological findings. The overall specificity of abdominal USG in the diagnosis of acute appendicitis was 88.09% and sensitivity was 95.37%.Conclusions:The Alvarado scoring system combined with ultrasound can therefore be used as a cheap and less expensive useful, reliable and non invasive way of confirming acute appendicitis thus helps in reducing negative appendectomy rate. The overall accuracy of diagnosis of acute appendicitis goes up to 90% with positive histopathological findings.

Background: Definitive diagnosis of acute appendicitis preoperatively is sometimes difficult. Failure to make a diagnosis is the main reason for persistent rate of morbidity and mortality. Various scoring systems are devised to aid diagnosis of acute appendicitis. In some studies the modified Alvarado score was helpful, reliable and practical in minimizing unnecessary appendectomy. Objective: The purpose of this study was to evaluate the usefulness of modified Alvarado score for the diagnosis of acute appendicitis. Materials and Method: A prospective study of 89 adult patients, admitted with abdominal pain suggestive of acute appendicitis, from July 2011 to June 2012, was conducted. Data including clinical signs and symptoms and laboratory findings were recorded in modified Alvarado score record form. All 89 patients underwent appendectomy. Final diagnosis was confirmed by histopathological examination. Reliability of scoring system was assessed by negative appendectomy rate and positive predictive value. Results: Out of 89 patients who underwent appendectomy, 85 had acute appendicitis on histopathology. Positive predictive value was 95.5% and negative appendectomy rate was 4.5%. 52.8% had score 7 or above and 47.2% had score less than 7. From score it is difficult to predict which patient warranted appendectomy and who may be safely observed or discharged. Conclusions: Diagnosis of acute appendicitis remains mainly clinical evaluation and it is more helpful than modified Alvarado scoring system in adults.Bangladesh Journal of Medical Science Vol.14(4) 2015 p.336-338

Introduction. The diagnosis of acute appendicitis (AA), as the most common cause of acute abdominal pain, has changed in the past decade by introducing scoring systems in addition to the use of clinical, laboratory parameters, and radiological examinations. This study aimed to assess the significance of the four scoring systems (Alvarado, Appendicitis Inflammatory Response (AIR), Raya Isteri Pengiran Anak Saleha Appendicitis (RIPASA) and Tzanakis) in the prediction of delayed appendectomy. Materials and methods. The study included 100 respondents, who were diagnosed with AA in the period from January 2018 to February 2019 and were also operated on. In addition to the clinical, laboratory, and ultrasonographic examinations, four scoring systems (Alvarado, AIR, RIPASA, and Tzanakis) were used to diagnose AA. According to the obtained histopathological (HP) findings, the patients were divided into 3 groups: timely appendectomy, delayed appendectomy and unnecessary appendectomy. Using the sensitivity and specificity of all 4 scoring systems, ROC analysis was performed to predict delayed appendectomy. Results. In the study that included 100 patients (58% men, 42% women), after the appendectomy was performed, the resulting HP showed that 74% had a timely appendectomy, while 16% had delayed and 10% had an unnecessary appendectomy. For the prediction of delayed appendectomy, the area under the ROC curve showed a value of 0.577 for the Alvarado score, 0.504 for the AIR, 0.651 for the RIPASA, and 0.696 for the Tzanakis. Sensitivity and specificity for the Alvarado score was 54% and 62%, for RIPASA 62.5% and 63.5%, for Tzanakis 69% and 60.8%, respectively. Combining the three scoring systems (Alvarado, RIPASA, and Tzanakis), the surface area under the ROC curve was 0.762 (95% CI 0.521–0.783), with a sensitivity of 85% and a specificity of 62%. Conclusion. In our study, the diagnostic accuracy of RIPASA and Tzanakis showed better results than Alvarado, while AIR cannot be used to predict delayed appendectomy in our population. However, the simultaneous application of all three scoring systems, RIPASA, Tzanakis and Alvarado, has shown much better discriminatory ability, with higher sensitivity and specificity, as opposed to their use alone. Combining scoring systems should help in proper diagnosis to avoid negative appendectomy, but additional studies with a larger number of patients are needed to support these results.

Objective: To compare the negative appendectomy in the females of reproductive and non-reproductive age groups. Study Design: Cross-sectional study. Place and Duration of Study: Department of Pathology, Diagnostic and Research Laboratory, Liaquat University of Medical and Health Sciences, Hyderabad, Pakistan, from January 2018 to December 2019. Methodology: A total of 1126 appendectomy specimens were enrolled irrespective of age and gender. The biodata of patients was retrieved from the database. Statistical analysis was done using SPSS version 22. Results: Out of total 1126 reported cases, 787 (69.9%) were males and 339 (30.1%) were females. The mean age was calculated to be 24.43 ± 12.42 years ranging from 2-94 years. Histopathological examination revealed cases of acute appendicitis 374 (33.2%), acute appendicitis with peri-appendicitis 478 (42.5%), fibrous obliteration 28 (2.5%) and parasitic infestation 7 (0.6%). Overall negative appendectomies were 219 (19.4%) and were prominent in females 100 (29.5%) than males 119 (15.1%). Also it was higher in females of reproductive age group 77 (30.4%) than in non-reproductive age group 23 (27.9%). Conclusion: In our study negative appendectomy in females of reproductive age groups was found to be higher than expected. Clinical scoring systems, biochemical markers, imaging modalities, and second opinion from other specialties like internal medicine, gynae and obstetric have been introduced to substantiate the diagnosis of acute appendicitis and thereby decreases the negative appendectomy.
