Objective. To verify the role of sonography in screening of acute appendicitis in patients admitted to an infectious disease unit for suspected acute infectious enteritis. Methods. One hundred eighty consecutive patients (102 male and 78 female; age range, 5-72 years; mean age, 31 years) admitted for suspected infectious enteritis or typhoid fever were prospectively studied with abdominal sonography within 48 hours after admission. None of the patients had peritoneal irritation. Forty-six patients (25%) had white blood cell counts of more than 10,000/mm 3 (range, 10,300-18,000/mm 3 ). The diagnosis of acute appendicitis was made when a detectable appendix with an anteroposterior diameter of greater than 7 mm could be seen on sonography. Results. Eleven (6%) of 180 patients had thickened appendixes (anteroposterior diameter range, 7-14 mm); 2 of them had periappendiceal abscesses. Four (36%) of 11 patients with acute appendicitis had high white blood cell counts. All sonographic diagnoses of acute appendicitis and periappendiceal abscesses were confirmed at surgery. Sonography ruled out acute appendicitis in 169 patients. In all of them, clinical and sonographic follow-up excluded the diagnosis of acute appendicitis. Normal appendixes were shown on sonography in 38 (22%) of 169 cases and were not detectable in 131 (78%) of 169. Conclusions. Sonography of the appendix is a useful method for early assessment of acute appendicitis in patients thought to have enteritis or typhoid fever.

“…In general, CT has been accepted as superior to US in the diagnosis of appendicitis, with higher sensitivity, specificity, and accuracy, and lower normal-appendix removal. The sensitivity, specificity, and accuracy of CT imaging were reported as 93-100%, 85-99%, and 94-97.6%, respectively, with higher ratios in men compared to women [5][6][7][8][9][10].…”

“…Cross-sectional imaging techniques, including ultrasonography (US), computed tomography (CT), and more recently, magnetic resonance imaging (MRI), have been successfully used to examine patients suspected to have appendicitis [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Because of technical improvements, US has been reported to reach sensitivities and specificities of up to 98% for diagnosis of acute appendicitis, a rate highly dependent on the experience of the sonographer [5,[11][12][13][14][15][16][17].…”

Aim: We aimed to establish the new and objective criteria that can be used for distinguishing the normal or pathological appendix from ileal segments sonographically. Materials and Methods:Long diameter, short diameter, mean diameter, circularity index (CI), and diameter index (DI) in mm on transverse images of normal and pathological appendices, and the others form of the ileum, were calculated.Results: DI, CI, long dimension show high sensitivity and specificity in discrimination of the normal or pathological appendix from ileal segments.Conclusion: DI, CI, and long dimension are effective and objective criteria for distinguishing normal or pathological appendix from ileum sonographically.

“…(3) The usefulness of high frequency probe and graded compression method has a high diagnostic value for acute appendicitis. (4,5) Superiority of Computed tomography compared to Ultrasonography is overemphasised by many studies (6,7,8,9,10,11) possibly because ultrasonography instrumentation was not very well developed at that time.…”

BACKGROUNDAppendicitis is a common cause for acute abdomen. Many literatures are available on imaging appendicitis and visualisation of normal appendix, but very limited studies for predominant contents of appendix by ultrasonography. Aim-To analyse contents of appendix in normal and inflamed appendix and to find if any content has association with inflammation of appendix and severity of inflammation.
