Accuracy of ultrasonography in the diagnosis of acute appendicitis.

Aims and Objectives: To assess the accuracy of ultrasonography in the diagnosis of acute appendicitis. Methodology: A prospective randomized study was carried in the Dept. of Radiology and Imaging, Tribhuvan University, Teaching Hospital, Maharajgunj, Kathmandu, Nepal. A total of 120 patients, who were clinically diagnosed as acute appendicitis were subjected to ultrasonography of the abdomen. A detailed ultrasonography was performed and the findings were recorded. Twenty one cases had alternate diagnosis. Ninety nine cases ultimately underwent laparotomy and the retrieved appendices were sent for histopathological examination. Intra-operative, histopathological and ultrasonographic diagnoses were then statistically analyzed. Results: Ultrasonographic, intra-operative and histopathological findings were statistically insignificant (P0.05). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy percentage of ultrasonography in the diagnosis of acute appendicitis was 85.7%, 100%, 100%, 6.7% and 85.9% respectively. Conclusion: Ultrasonography has a high degree of accuracy in the diagnosis of acute appendicitis. However, the diagnosis should be considered with the diameter of appendix over 6 mm. Therefore acute appendicitis with diameter of appendix having less than 6 mm should be evaluated with other diagnostic parameters. Key words: Acute Appendicitis, Ultrasonography.

Ultrasonography of acute abdominal pain in children

OBJECTIVE.--To determine the ability of ultrasonography to detect appendicitis and to identify other conditions responsible for symptoms in children with acute abdominal pain. DESIGN.--Cohort study. The accuracy of ultrasonographic results was assessed in relation to final diagnoses established by surgery or by composite clinical data and follow-up. SETTING.--Metropolitan, pediatric hospital; ambulatory and hospitalized patients. PATIENTS.--Consecutive sample of 178 pediatric patients who were referred for ultrasonography because of suspected acute appendicitis, but in whom the diagnosis could not be definitively established by clinical criteria. RESULTS.--Appendicitis was proven at surgery in 38 patients. Ultrasonography demonstrated the findings of appendicitis (noncompressible appendix with or without concomitant periappendiceal fluid collection or appendicolith) in 31 (82%) of these patients. Among the 140 children without appendicitis, other specific diagnoses were established by clinical, laboratory, and radiologic findings in 58 patients (including gynecologic diseases in 25, gastrointestinal tract abnormalities in 17, renal diseases in six, and extra-abdominal disease in 10). Ultrasonography aided in the diagnosis of other conditions in 34 (59%) of these 58 patients. No definitive clinical diagnosis was established in the remaining 82 patients. There were no false-positive results of ultrasonography. CONCLUSION.--Approximately half of children referred for suspected appendicitis will have a final diagnosis of abdominal pain of unknown origin. In the remainder, ultrasonography is useful, both to establish the diagnosis of appendicitis and to aid in diagnosing other causes of acute abdominal pain.

Computed tomography and ultrasonography in the diagnosis of equivocal acute appendicitis. A meta-analysis

Acute appendicitis is the most common acute surgical condition of the abdomen. Computed tomography (CT) and Ultrasonography (US) can reduce the rate of complications and unnecessary appendectomies, in addition, they can establish an alternative diagnosis. We carried out a systematic review to evaluate the evidence relating radiological imaging (US and CT scan) and early detection of acute appendicitis in patients presenting with equivocal findings, and to provide recommendations to use radiological imaging (US and CT scan) in diagnosing acute appendicitis as part of the initial clinical assessment of the patients presenting with equivocal findings to reduce complications and unnecessary appendectomies. We used the MEDLINE to search for articles published from 1966 to December 2005 that related to radiological imaging of acute appendicitis; additional articles were identified from the bibliographies of review articles. Selection criteria were used to limit the analysis to prospective studies with more than 100 patients involved in each study as a study group. Forty-five studies fulfilling our inclusion and exclusion criteria were extracted, and 13,046 patients were included. Although the CT scan was more sensitive than US in diagnosing patients with equivocal appendicitis (93.4% [95% CI 92.1-94.6] versus 83.7% [95% CI 82.3-85.0]), either diagnostic study should be used as part of the initial assessment of the patients presenting with equivocal findings.
