RESUMEN

PURPOSE: This study evaluated the usefulness of a new scoring system in diagnosing acute appendicitis which expresses the patient's symptoms, physical examination, and laboratory findings more clearly and objectively. METHODS: A prospective study was conducted with 314 patients who were hospitalized with suspicion of acute appendicitis. After analyzing the symptoms, physical examination, and laboratory findings, 10 meaningful variables were selected, each of which were scored separately. The diagnostic value of the new scoring system was evaluated, and analyzed in comparison to the preexisting Alvarado score. RESULTS: Ten variables including vomiting, migration pain, fever, Dunphy's sign, Rovsing's sign, tenderness, rebound tenderness, increased white blood cell counts, increased neutrophil proportion, and increased CRP levels were associated with acute appendicitis. The new scoring system is developed by applying 1 point for each variable, with a total score of 10 points. In the new scoring system, a score above 5 points had sensitivity of 0.75, specificity of 0.73, positive predictive value of 0.92, and diagnostic accuracy of 0.71. The area under the receiver operating characteristic curve was 0.80, which is larger than 0.72 of the preexisting Alvarado score, and thus has a higher diagnostic accuracy. As acute appendicitis progresses, the average score tends to become significantly higher (P=0.001). CONCLUSION: The new scoring system, which objectively reflects the clinical variables of the patient's symptoms, physical examination and laboratory findings, will be useful in accurately diagnosing acute appendicitis and in quickly deciding a therapeutic policy in patients with right lower abdominal pain.

RESUMEN

PURPOSE: The modified triple test (MTT; physical examination, ultrasonography, and fine-needle aspiration cytology) for palpable breast masses yielded 100% diagnostic accuracy when all 3 components were concordant (all benign or all malignant) in our previous study. However, about 30% of cases were discordant and required open or core needle biopsy. This study is designed to evaluate the modified triple test by scoring system, based on our experience, and to develop a method to further limit the need for surgical biopsy of discordant cases. METHODS: The MTT was performed in 175 palpable breast masses of 166 female patients between August 1998 and June 2001 at the Outpatient Clinic, Department of Surgery, Chungbuk National University Hospital. Each component of the MTT was assigned 1, 2, or 3 points for a benign, suspicious, or malignant result, respectively, yielding a total modified triple test score (MTTS) from 3 to 9 points, and 25 cases with 3 points of MTTS were clinically followed up without histological confirmation. RESULTS: Among 175 cases, concordant cases were 120 (68.6%); benign cases was 66 (37.7%), and malignant cases were 54 (30.8%). Concordant cases had 100% of diagnostic accuracy, sensitivity, and specificity. Among the 25 cases of benign concordant (MTTS 3 points), no case was proved to be malignant through clinical follow-up observation. Total discordant cases were 55 (31.4%); 15 cases of 4 points (8.6%), 11 cases of 5 points (6.3%), 4 cases of 6 points (2.3%), 18 cases of 7 points (10.3%), 7 cases of 8 points (4.0%). In each discordant group, 0 cases of 4 points (0%), 2 cases of 5 points (18.2%), 3 cases of 6 points (75%), 15 cases of 7 points (83.8%), and 7 cases of 8 points (100%) were proved to be malignant by histologic confirmation. Aspiration cytology has the highest specificity and positive predictive value of the 3 MTT components. CONCLUSION: Palpable breast masses that score 3 or 4 points by MTTS are benign and could be clinically followed up, and masses that score 8 or 9 points are malignant and should undergo defiitive therapy. Confirmatory biopsy might be applied on only 20% of the masses the reserve MMTTS of 5, 6, and 7 points.
