| Summary: | Background: Acute abdomen is the most commonly attended surgical emergency. It can be caused by intra-abdominal, extra-abdominal and metabolic causes. A few imaging modalities are at disposal of primary care physicians like plain x-ray and ultrasonography. Materials and Methods: This study has been done to compare the efficacy of clinical diagnosis, plain radiography and sonography in diagnosis of non-traumatic acute abdomen. Every patient under study admitted in the Department of General Surgery underwent thorough clinical evaluation, biochemical investigations, X-rays and sonography. Findings of clinical evaluation, X-Rays and sonography were compared to the final diagnosis found intraoperatively. Results: Clinical diagnosis was made in 47 (94%) out of 50 patients. X-rays were able to diagnose in 20 patients (40%) whereas sonography diagnosed 26 patients (52%). Conclusion: The present study showed that clinical evaluation, x-rays or Ultrasound alone are not sufficient to diagnose cause of non-traumatic acute abdomen in all cases. Clinical evaluation combined with x-rays and ultrasound increases the number and accuracy of pre-operative diagnosis in non-traumatic acute abdomen.
