Abstract

Background:A prospective observational study of 105 operated cases of non-traumatic acute abdomen in emergency setting in tertiary government hospital was carried out. The correlation between preoperative diagnostic, radiological and clinical assessment and operative findings was noted. The clinical and radiological diagnostic accuracy rates were calculated using descriptive statistical analysis. Negative laparotomy rates were calculated and compared to the previous studies.

Methods: The most common finding was acute appendicitis and the most frequently involved age group was 21-40.The absence of correlation between preoperative diagnosis and operative findings was noted in 7 cases of which 2 cases of appendicitis had been missed on ultrasound and 2 cases of appendicular mass were reported as acute appendicitis where appendectomy could not be done on account of adhesions.2 cases of x-ray diagnosed obstruction with clinical features of vomiting ,constipation had no gross bowel pathology on laparotomy while one case diagnosed preoperatively as appendicitis turned out to be a case of renal colic with hydroureter.

Results:The diagnostic accuracy rate of x-ray and ultrasound for obstruction/perforation and acute appendicitis were found to be 89.79% and 94.64% respectively.

Conclusions:The negative laparotomy rates were low around 2.85%.
