Abstract

Acute abdomen is the most common cause for surgical admission. Computed tomography (CT) scans are increasingly used to aid early diagnosis. Considering significant disease burden, role of CT in evaluation of patients with non-traumatic acute abdomen needs further evaluation. Thus, the present study was performed to evaluate role of CT scan in determination of etiological spectrum in non-traumatic acute abdomen. Materials and Methods: The present study was a prospective, observational, single centre study over a period of 2 years. Patients were initially subjected to USG abdomen. Patients with positive findings on USG and those with clinically suspected abdominal cause of acute pain were subjected to CT abdomen. The categorical and continuous variables are represented as frequency (percentage) and mean (standard deviation, SD), respectively. Results: In the present study, majority of patients were young males. In the present study, according to the systems affected, majority of the patients had urinary tract pathology (38.75%) followed by hepatobiliary pathology (30%), and GI pathology (17.50%). Of 43 patients that were managed surgically, the surgical findings correlated with CT findings in 41 patients. Moreover, the Ultrasonography (USG) findings correlated with CT findings in 44 patients. Thus, CT scan and USG were diagnostic in 95.35% and 55% patients. Conclusion: In the present study, non-traumatic acute abdomen mainly affected urinary tract and hepatobiliary system. In majority of patients surgical findings correlated with CT findings. Moreover, the USG findings correlated with CT findings in limited number of patients.
