Correlation of histological diagnosis and laboratory findings in distinguishing acute appendicitis and lymphoid hyperplasia.

Purpose: Acute appendicitis (AA) is one of the most frequent causes of abdominal surgery encountered in emergency rooms. However, reactive lymphoid hyperplasia (RLH) is one of the appendicular pathologies often misdiagnosed. It is quite challenging to distinguish between AA and RLH in terms of planning treatment in an emergency. Therefore, this retrospective study aimed to compare the histological and laboratory findings of AA and RLH. Methods: The retrospective data included in the study were obtained from patients diagnosed with AA. Complete blood count (CBC) and C-reactive protein (CRP) levels of patients with AA and RLH were compared before the surgery based on the histological diagnosis of the patients. Results: A total of 187 patients who previously underwent appendectomy were included in the study. Histopathological examination revealed that 152 patients (81.3%) were diagnosed with AA, and 35 (18.7%) with RLH. While white blood cell count (P < 0.001), neutrophil (P < 0.001), and neutrophil/lymphocyte ratio (P < 0.001) were found to be significantly higher in those with AA; lymphocyte (P = 0.003) and eosinophil counts (P = 0.033) were detected to be significantly higher in those with RLH. CRP level was also significantly higher in those with AA (P = 0.002). Conclusion: We consider that CBC and CRP levels may be predictive in distinguishing between AA and RLH. We consider that these parameters may be valuable in making a distinction between patients before surgery.

Association between red blood cell distribution width and acute pancreatitis.

BACKGROUND: We aimed to determine whether there are any alterations in red blood cell width in patients diagnosed with acute pancreatitis. MATERIAL/METHODS: This was a retrospective study of records of patients treated in emergency units and diagnosed with acute pancreatitis between January 2011 and April 2013. Records were investigated regarding patient age, sex, and causes of acute pancreatitis. Red blood cell width and amylase values obtained from the patients during diagnosis and after a full recovery from acute pancreatitis were added to the records. RESULTS: Recorded red blood cell width and amylase values of 104 patients diagnosed with acute pancreatitis were statistically compared according to the time of sample collection. Samples were collected in the post-diagnostic period and after full recovery. Values of red blood cell width and amylase were found to be significantly higher in samples collected during hospital admission in comparison to those obtained from patients after fully recovering from acute pancreatitis (p<0.05). CONCLUSIONS: An increase in red blood cell width value is a marker of acute pancreatitis; therefore, we suggest that red blood cell width can be used as a tool for the early diagnosis and assessment of disease progression.
