Validity of ultrasound examination in the diagnosis of acute appendicitis compared with surgical results

Objective: To assess the validity of ultrasound examination in the diagnosis of acute appendicitis. Methods: This case series study included 750 patients. From January 2003 to March 2007, patients with suspected acute appendicitis were sent to the radiological section in the ALJamhory teaching hospital and my private clinic for sonography. A distended appendix with a lumen more than 6mm, aperistaltic appendix with appendicolith in its lumen are all signs and criteria for the diagnosis of acute appendicitis. Result: Of the 750 patients suspected to have acute appendicitis who were examined by sonography, 527 were males and 223 females. 468 patients had true acute appendicitis, and 220 patients were negative for this disease. Thirty patients showed false positive diagnosis, while 32 patients proved to have false negative results. The overall sensitivity of ultrasound examination to diagnose acute appendicitis was 94%, specificity 88%, accuracy 92%, positive predictive value 93% and negative predictive value was 88%. Conclusion: sonography must be used as first modality to assess suspected acute appendicitis. It is easy, non invasive, simple and rapid. ةصلاخلا : فدهلا : داحلا ةيدودلا ةدئازلا باهتلا هابتشا تلااح صيخشت يف ةيتوصلا قوف تاجوملا صحف ةيمهأ مييقتل . ثحبلا مييقت : ةيضرم تلااحل ةيفصو ةسارد . نوآراشملا : ٧٥٠ داحلا ةيدودلا ةدئازلا باهتلا هابتشاب نوباصم اضيرم . ينمزلا راطلإاو ثحبلا ءارجإ ناكم : ةساردلا تيرجأ م يف ةعشلأا ةبعش يف . لا يروهمج ةصاخلا ةدايعلاو يميلعتلا يناثلا نوناآ ذنم لصوملا يف ٢٠٠٣ راذآ ىتحو ٢٠٠٧ . ةساردلا قرط : تلمشو دا حلا باهتللاا ى لع ة لدأآ ة يلاتلا تافصلا دا متعا م تو ىضرملل ةيدودلا ةدئازلا صحف مت نم رثآأ اهفيوجت رطق حبصي ثيحب ةيدودلا ةدئازلا خافتنا ٦ ملم , ةدئازلل ةيضبنلا ةآرحلا نادقف , بيرغ مسج دوجو اهدادسنلا اببسم ةدئازلل فيوجتلا لخاد . جئاتنلا : ةسارد مت ) ٧٥٠ ( ةيدودلا ةدئازلا باهتلا هابتشاب نيباصم اضيرم . ٥٢٧ و روآذلا نم ٢٢٣ ةباصإ ني بت ثانلإا نم ٤٦٨ لا ءارجإب تبثملا داحلا ةيدودلا ةدئازلا باهتلاب اضيرم يحارجلا لخادت , ناآ امنيب ٢٢٠ اذه نم اميلس اضيرم
