Sonuç: Bu çalışma sonucunda, ADKG'nin, akut apandisit düşünülen olgularda, negatif laparotomi oranını azaltamayacağı öne sürülmektedir. Background/Purpose: Upright plain abdominograph (UPAC) still remains as one of the most frequently used roentgenographic modalities in the diagnosis of acute appendicitis. In this study, we aimed to evaluate the role of UPAG in the diagnosis of acute appendicitis. Method: The clinicopathological diagnoses and plain abdominal X-rays of 93 children (55 boys, 38 girls) operated with diagnosis of acute appendicitis were evaluated retrospectively. An experienced radiologist was blinded to the postoperative diagnoses. Thirteen roentgenographic criteria related with appendicitis were noted and compared with histopathological diagnoses. Data was analysed by Fisher's exact test and positive and negative predictive values of UPAG in the diagnosis of acute appendicitis were determined. Results: Mean age was of 9.5 years (13 months-15 years). 81 patients had acute appendicitis and 12 had a normal appendix. At least one or more roentgenographic criteria were detected in 75 (81 %) cases. 66 of the cases had appendicitis and 9 had a normal appendix. The most frequent findings were lumbar scoliosis with left-sided convexity (49 pts. 52 %) and air-fluid levels in the small intestines (36 pts. 38 %). In 18 cases no diagnostic criteria was detected. In all of the perforated cases, at least one of the determined criteria was seen. It was interesting that while radiological sign (s) was noted in 9 pts. Without appendicitis, no sign was seen in 15 cases with appendicitis. The difference in the percentage of roentgenographic signs found in cases with and without appendicitis was not significant (p>0.05). The negative predictive value of UPAG in the diagnosis of acute appendicitis was 17 % and positive predictive value was 88 %. Conclusion: It is concluded that UPAG does not decrease the rate of negative laparotomies in children having a preoperative diagnosis of acute appendicitis."> [PDF] Akut apandisitte konvansiyonel radyografik bulgular | [PDF] Conventional X-ray findings in acute appendicitis 0.05).
