Abstract

Aim: The purpose of the study was to evaluate the clinical validity of the urinary tripsinogen-2 strip test in the diagnosis of acute pancreatitis. Methods: The prospective study consisted of 200 consecutive patients admitted to the emergency unit with acute abdominal pain. The urinary and blood samples of these patients were analyzed for urinary and blood amylase and urinary tripsinogen-2 levels. The results were evaluated for sensitivity, specificity, positive and negative predictive values, accuracy rate and relative risk ratio. Continous data were compared by the Mann-Whitney U test and test strip results were compared by McNemar's test. Results: In 16 of the 200 patients with abdominal pain, the diagnosis of acute pancreatitis could be established. The sensitivity of the urinary tripsinogen-2 strip test, urinary and serum amylase results were 98%, 81%, 88% and specificity were 95%, 94% and 93%, respectively. The positive and negative predictive values were 61%, 54%, 52% and 99%, 98%., 99%, respectively. The accuracy rate and relative risk ratio of these tests "were 95%, 93%, 93% and 53.87, 31./78, 44.85 respectively.Conclusions: The three tests studied were not significantly different from each other in terms of the parameters taken into account. But the urinary tripsinogen-2 strip test can be considered a valuable non invasive, simple urinary screening test in the diagnosis of acute pancreatitis especially in subclinical cases.

Özet

Amaç: Akut pankreatitin erken ve doğru tanısında tripsinojen-2'nin idrardaki artışının tanısal değerini belirlemek. Yöntem: Acil Cerrahı Polikliniğine 2003 Nisan - Mayıs aylarında başvuran kesin tanı konulmamış akut abdomen ön tanılı 200 hasta incelendi. Alınan idrar ve serum örneklerinde amilaz ve üriner tripsinojen-2 strip testi (Actim pankreatit testi) ölçümleri yapıldı. Elde edilen sonuçlar ile duyarlılık, özgüllük, pozitif kestirim değeri, negatif kestirim değeri, doğruluk oranı ve göreli risk değerleri hesaplandı. Sürekli veri Mann-Whitney U testi ile, strip testi sonuçları ise McNemar testi ile karşılaştırıldı. Bulgular: Yaş ortalaması 57 yıl olan 16 hastada akut pankreatit tanısı konuldu. Bu hastalarda üriner tripsinojen-2 strip testi, üriner amilaz değeri ve serum amilaz değerlerinin duyarlılığı sırasıyla %88, %81 ve %88 olarak, özgüllük %95, %94 ve %93 olarak, pozitif kestirim değeri %61, %54 ve %52 olarak, negatif kestirim değeri %99, %98 ve %99 olarak, doğruluk oranları %95, %93 ve %93 olarak, göreli risk oranı ise 53.87, 31.78 ve 44.85 olarak bulundu. Sonuç: Akut pankreatit tanısında her üç testin duyarlılık, özgüllük, pozitif ve negatif kestirim değerleri, doğruluk ve göreli risk oranları açısından anlamlı farklılık tespit edilememiştir. Ancak üriner tripsinojen-2 strip testi non-invazif, basit bir izleme testi olması nedeniyle acil durumlarda, tanı konulamayan akut pankreatitlerin tanısında yararlı olabileceği kanısına varılmıştır.
