Background: Acute Appendicitis is common surgical emergencies with a lifetime prevalence of approximately 1 in 7. Despite advances in diagnosis and treatment; acute Appendicitis is still associated with morbidity (10%) and mortality (1-5 %). Presentations of acute Appendicitis can mimic various acute medical and surgical conditions, and the diagnosis is predominantly a clinical one-different scoring systems used for aiding in early diagnosis of Acute Appendicitis and its prompt management. Alvarado score and RIPASA score are the most popular ones. So we retrospectively applied and compared Alvarado and RIPASA score in the diagnosis of acute Appendicitis in Indian population.Methods: In this study, we compared RIPASA score and Alvarado scoring system retrospectively by applying to 74 patients. This study period from November 2018 to March 2020. Both scores were calculated for patients presented with right iliac fossa pain. Sensitivity, specificity, positive predictive value (PPV), negative predictive (NPV), diagnostic accuracy for RIPASA and Alvarado system was calculated.Results: The sensitivity and specificity of the Alvarado score were 85.07% and 57.14% respectively. The sensitivity & specificity of RIPASA score were 91.04% and 71.42% respectively. Accuracy of the Alvarado scoring system is 82.44% and for RIPASA scoring system is 89.18%. The results show that the RIPASA scoring system is a better diagnostic tool for the diagnosis of Acute Appendicitis.Conclusions: RIPASA scoring system is simple, accurate, convenient, and more specific scoring system than the modified Alvarado scoring system for the Indian population.

Acute appendicitis is the most common condition encountered in the Emergency department .Alvarado and Modied Alvarado scores are the most commonly used scoring system used for diagnosing acute appendicitis.,but its performance has been found to be poor in certain population . Hence our aim was to compare the diagnostic accuracy of RIPASA and ALVARADO Scoring system and study and compare sensitivity, specicity and predictive values of these scoring systems. The study was conducted in Government district hospital Nandyal . We enrolled 176 patients who presented with RIF pain . Both RIPASA and ALVARADO were applied to them. Final diagnosis was conrmed either by CT scan, intra operative nding or post operative HPE report. Sensitivity,specicity, positive predictive value, negative predictive value, diagnostic accuracy was calculated both for RIPASA and ALVARADO. It was found that sensitivity and specicity of the RIPASA score in our study are 98.7% and 83.3%, respectively. PPV and NPV were 98.1% and 88.2% and sensitivity and specicity of the Alvardo score in our study are 94.3% and 83.3%, respectively. PPV and NPV were 98% and 62.5%.Diagnostic accuracy of RIPASA score and Alvarado score are 97% and 93% respectively. RIPASA is a more specic and accurate scoring system in our local population when compared to ALVARADO . It reduces the number of missed appendicitis cases and also convincingly lters out the group of patients that would need a CT scan for diagnosis (score 5-7.5 ) BACKGROUND: Acute appendicitis is one of the most commonly dealt surgical emergencies, with a lifetime prevalence rate of approximately 1 one in seven. The incidence is 1.5–1.9 per 1,000 in the male and female population, and is approximately 1.4 times greater in men than in women. Despite being a common problem, it remains a difcult diagnosis to establish, particularly among the young, the elderly and females of reproductive age, where a host of other genitourinary and gynaecological inammatory conditions can present with signs and symptoms that are 2 similar to those of acute appendicitis. A delay in performing an appendectomy in order to improve its diagnostic accuracy increases the risk of appendicular perforation and peritonitis, which in turn increases morbidity and mortality. A variable combination of clinical signs and symptoms has been used together with laboratory ndings in several scoring systems proposed for suggesting the probability of Acute Appendicitis and the possible subsequent management pathway. The Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) and ALVARADO score are new diagnostic scoring systems developed for the diagnosis of Acute Appendicitis and has been shown to have signicantly higher sensitivity, specicity and diagnostic accuracy. AIMS AND OBJECTIVES PRIMARY OBJECT 1. To compare RIPASA Scoring system and ALVARADO Scoring system in terms of diagnostic accuracy in Acute Appendicitis. 2. To study and compare sensitivity, specicity and predictive values of above scoring systems. SECONDARY OBJECT 1. To study the rate of negative appendicectomy based on above scoring systems. CONCLUSION: The RIPASA score is a simple scoring system with high sensitivity and specicity for the diagnosis of acute appendicitis. The 14 clinical parameters are all present in a good clinical history and examination and can be easily and quickly applied. Therefore, a decision on the management can be made early. Although the RIPASA score was developed for the local population of Brunei, we believe that it should be applicable to other regions. The RIPASA score presents greater Diagnostic accuracy and Sensitivity and equal specicity as a diagnostic test compared to the Alvarado score and is helpful in making appropriate therapeutic decisions. In hospitals like ours, the diagnosis of AA relies greatly on the clinical evaluation performed by surgeons. An adequate clinical scoring system would avoid diagnostic errors, maintaining a satisfactory low rate of negative appendectomies by adequate patient stratication, while limiting patient exposure to ionizing radiation, since 21 there is an increased risk of developing cancer with computed tomography, particularly for the paediatric age group.

Background: The RIPASA Score is a new diagnostic scoring system developed for the diagnosis of Acute Appendicitis which showed higher sensitivity, specificity and diagnostic accuracy compared to ALVARADO Score, particularly when applied to Asian population. Not many studies have been conducted to compare RIPASA and ALVARADO scoring systems. Hence, author want to compare prospectively Alvarado and RIPASA score by applying them to the patients attending the hospital with right iliac fossa pain that could probably be acute appendicitis.Methods: A prospective analysis of 116 cases admitted with RIF pain during a 2 years period was performed. Patients between 15-60 years were scored as per Alvarado and RIPASA scoring system. Histopathological reports of the cases were collected and compared with the scores. ROC curve area analysis was performed to examine diagnostic accuracy of RIPASA and ALVARADO scores.Results: The sensitivity of ALVARADO score is estimated to be 52.08 for a cut off of 6. The specificity is 80%, positive predictive value is 92.59, negative predictive value is 25.81. The Diagnostic accuracy of ALVARADO scoring is found to be 56.9. The sensitivity, specificity, positive predictive value and negative predictive values of RIPASA scoring system are 75%, 65%, 91.14%, 35.14%. The diagnostic accuracy of RIPASA score is 73.28.Conclusions: The difference in the diagnostic accuracy between ALVARADO and RIPASA scoring system is significant indicating that the RIPASA score is a much better diagnostic tool for the diagnosis of acute appendicitis. When the ROC curve was observed the area under the curve is high for RIPASA scoring system.

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.

Background: Acute appendicitis is one of the commonest surgical emergencies in all ages. Diagnosis is mainly clinical, delay in diagnosis definitely increases the morbidity, mortality and cost of treatment, more aggressive surgical approach has resulted in increased white appendectomies.Methods: A total 100 cases hospitalized with abdominal pain, suggestive of acute appendicitis on the basis of modified Alvarado scoring system and were subsequently operated, were included in the present study in our institute for period of 20 Months.Results: Males belonging to young age group of 21-30 were most commonly affected. Abdominal pain was seen in 100% of patients. Fever seen in 87% of patients and vomiting in78%. Modified Alvarado score of 9 had positive predictive value of 100% while negative predictive value 8.9%, while score between 7-8 had positive predictive value of 98.9% and negative predictive value 27.8%. The sensitivity was 86.1% and specificity was 83.3%. The ultrasonography showed a sensitivity of 94.68%. In present study rate of total white appendectomy was 6%. The Modified Alvarado scoring system is a reliable and practicable diagnostic modality to increase the accuracy in diagnosis of acute appendicitis and thus to minimise unnecessary appendectomy.Conclusions: Young males are most commonly affected almost always presents with abdominal pain. The Modified Alvarado scoring system is a reliable and practicable diagnostic modality to increase the accuracy in diagnosis of acute appendicitis and thus to minimise unnecessary appendectomy.

Background: Acute appendicitis remains as one of the most common surgical entity requiring early intervention. Hence there is always a need to develop a well-designed protocol for diagnosis and to reduce negative appendectomy. The most common and widely applied was Alvarado score and best performed in validating studies, but was observed with few drawbacks. A recently introduced appendicitis inflammatory response score (AIR) was designed to overcome the drawbacks associated with the implementation of Alvarado scoring system. The objective the present study was to evaluate the AIR score on cases of suspicious appendicitis and to compare it with Alvarado scorings system.Methods: A prospective study for a period of two years from March 2015 to February 2017 was conducted on consecutive patients who presented to emergency department and scoring was performed based on the necessary variables.Results: The present study was conducted on 300 cases suspicious of appendicitis. The results analysed showed the area under the ROC curve of the AIR score was 0.94 and better than the area under the curve of Alvarado score of 0.82. The AIR score also did well in difficult cases of women, children when compared to Alvarado score in diagnosis of appendicitis. In our study, in cases with >8 points, a lower sensitivity was observed in AIR scoring than Alvarado scoring (0.26 vs. 0.12), but was associated with higher specificity (1.00 vs. 0.95). In these cases, PPV turned out to be 1.00 for AIR scoring and 0.77 for Alvarado scoring.Conclusions: To conclude, AIR scoring performed well almost equally with Alvarado system with high specificity and high negative predictive value preventing unnecessary negative appendectomies. Follow up of these cases will help in deciding surgical intervention in unnecessary cases. This scoring system also prevents unnecessary and costly radiological investigations thereby reducing the financial burden to the patients.
