“…Emergency service physicians encounter patients with abdominal pain many times a day and try to differentiate between these diagnoses. Tan and et al [5] have stated that abdominal CT is especially important for suspected cases for diagnosis in their study. They have found that patients undergoing CT evaluation have a negative appendectomy rate of 5.7% compared to 17.9% in those without CT evaluation in suspected cases.…”

“…In cases where differential diagnosis is challenging, an experienced ultrasonographer cannot be always accessible. [5] Non-contrasted and/or contrast-enhanced abdominopelvic tomography (CT) requires a specialist for its interpretation, not mentioning exposure to the risks of radiation and contrast agent hypersensitivity. This condition can leave the patient and the physicians in a difficult dilemma.…”

BACKGROUND:Only one diagnostic parameter is not available for acute appendicitis. For the establishment of diagnosis, combination of medical history, clinical, laboratory tests, and radiological imaging modalities are used so as to decrease the rates of negative laparotomy and morbidity secondary to delay in diagnosis. Thepresent study aimed to determine haematological and inflammatory markers which will be used in the discrimination of acute appendicitis (AA) and renal colic which are the most frequent and indistinguishable causes of abdominal pain in patients applying to the emergency service.

“…numerous scoring systems evaluating clinical symptoms and blood tests to increase the prognostic accuracy of appendicitis have been designed (7)(8)(9). However, none of the scoring systems evaluate the risk of appendiceal perforation, and none of the scoring systems use a combination of blood markers.…”

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 nonperforated 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.

Alvarado score: a guide to computed tomography utilization in appendicitis

Abstract: In suspected appendicitis, patients who benefit from CT evaluation are those with the AS ranging from 4 to 8. We propose a management algorithm with the AS guiding the necessity for CT evaluation.
