to evaluate the value of ultrasonography in the diagnosis of acute-appendicitis, in clinically suspected cases.
Methodology: This prospective observational study was carried out at DHQ Teaching hospital, Khyber Medical University,Institute of Medical Sciences Kohat, Pakistan from Feb-2009 to Nov-2011. This study included 150 patients with a clinicalsuspicion of acute-appendicitis. The ultrasound findings were compared with histopathological outcome of the case,which was taken as gold standard. In the radiology department, color Doppler ultra sound machine, Accucie Toshibawith a 7.5 MHz, abdominal probe was used. All the exams were performed by a single senior radiologist.
Out of 150 patients, 112 (74.7%) were male and 38 (25.3%) were female. Age ranged from 12 to 60 years. Onthe basis of ultrasonography, 100 (66.7%) patients were labeled as positive for acute-appendicitis and 50 (33.3%) patientsas negative for acute-appendicitis. Out of 100 positive patients, 79% patients were confirmed as acute-appendicitis onhistopathology and 21% had normal appendix on histopathology. Out of 50 negative patients, 12 (24%) patients had rightureteric calculus and 6 (12%) patients had acute cholecystitis while 5 (10%) patients were explored later on becauseof persistent pain and progressing symptoms and a diagnosis of acute-appendicitis was confirmed on histopathology.
In clinically suspected cases of pain right iliac fossa, the use of ultrasonography is valuable to establishacute appendicitis or alternate diagnosis. It can be recommended as a valuable screening tool in clinically suspectedcases of acute-appendicitis.
