The diagnostic value

of CRP in the overall patient with acute abdominal pain showed a sensitivity of 79%, specificity of 64% and global accuracy of 73% for predicting subsequent hospitalization using a cut-off value for positive test of >5 mg/L [2]. More recently, Salem et. al. [5] reviewed the diagnostic value of CRP in true find more surgical patients with acute abdominal pain in the ED. They concluded that CRP alone is not useful in differentiating between surgical causes of acute abdomen or self-limiting condition [5]. In addition, CRP can neither differentiate between surgical conditions requiring SCH772984 nmr intervention from those who can be treated non-operatively [5]. In conclusion, these studies confirm the difficulty to diagnose an acute abdomen and assessing the need for a laparotomy as in our cases. Although high CRP levels or increase in CRP concentrations are seen in combination with abdominal complaints, it does not directly mean that a surgical

complication should be the problem. When CRP is compared with lactate, Epacadostat one study concluded that CRP is as a poor marker for the diagnosis of an acute abdomen considering that its activation is later in the onset of the disease compared to lactate or Interleukin-6 (IL-6) [1, 5]. Patient with severe sepsis and those with sepsis on the ED with an acute abdomen can superiorly be differentiated by levels IL-6 and lactate [1]. But this study only included patients with sepsis or shock. From our cases and a review of literature it is clear that we need more reliable markers to help establishing a fast and reliable diagnosis of patients with acute abdominal pain. Recently,

the newer biomarker procalcitonin (PCT) showed to be a reliable marker to differentiate bacterial from nonbacterial infection or noninfectious inflammation with high accuracy [6]. Prospective studies on the use of PCT as screening test for appendicitis on the ED showed that this marker may only be useful in identifying patients with complicated (severe) appendicitis [7, 8]. Furthermore, procalcitonin has also been proven to be helpful during the diagnosis or exclusion of acute mesenterial ischemia, intestinal ischemia or necrosis in acute bowel obstruction and abdominal sepsis [9–11]. Liothyronine Sodium Its use may be considered as additional tool to improve clinical decision making and appropriate therapy. Imaging modalities have proven to be valuable adjuncts in diagnosis patients with acute abdominal pain. In one patient the CT-scan revealed no abnormalities and neither did the following laparotomy. The third patient did not have abdominal pain and the CT-scan showed potential bile peritonitis. The critical illness of the patient with abnormal increase in CRP and lactate concentration pushed the surgeons to perform a laparotomy, again without abnormalities. Perhaps, it should be recommended that all patients with acute abdominal pain and increased CRP and/or lactate levels should additionally undergo a CT-scan [12].
