Comparative study between clinical diagnosis, plain radiography and sonography for the diagnosis of nontraumatic acute abdomen.

Abstract

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. 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. 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%). 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.
