An Investigation of the Sensitivity of Laboratory Tests and Sonography Results in Diagnosis of Acute Cholecystitis in One of the Dezful Hospitals in 2014-15

One of the most common surgical problems was acute cholecystitis. Accurate and timely diagnosis to start proper treatment and to decrease mortality rate is very essential. Due to contradictory results regarding diagnostic methods in acute cholecystitis, this study investigated the sensitivity of laboratory tests and sonography results in diagnosis of acute cholecystitis.
This cross-sectional study was performed using all people records that had cholecystectomy with diagnosis of acute cholecystitis in Dezful large hospital in 1393. Laboratory findings included the number of leukocytes, levels of AST, ALT, alkaline phosphatase, direct and indirect bilirubin and ultrasound that compared with pathological findings as definitive diagnosis. Data were analyzed using SPSS statistical software (version 18), and descriptive statistics and Pearson's correlation coefficients were employed.
In this study, 67 patients’ records were included with a mean age of 47.58 ± 17.36 years (23 patients (%34.3) were male and 44 patients (%65.7) were female). Positive predictive value or sensitivity was %56.1 for WBC, %34.2 for alkaline phosphatase, %37.5 for AST, ALT (50%), direct bilirubin (%77.4), % 62.1 indirect bilirubin and (% 96.2) for ultrasound.
Due to the ease of access to ultrasound and liver enzymes and their values obtained in this study, they can guide us to the cost – effective diagnosis.
