5 CONCLUSIONS
Elderly patients with abdominal pain present to hospitals later due to the obscurity of their symptoms and signs. The high rates of comorbidities in the elderly also lead to more complicated appendicitis. This results in an increased rate of postoperative complications and longer hospital stay. The USG and CT modalities used for diagnosis have almost the same, or sometimes even lower sensitivity and specificity values compared to the laboratory parameters examined here. Preoperative WBC, neutrophil, NLR, MPV, CRP, and direct and total bilirubin levels can be used in the diagnosis of AA in elderly patients. Again, NLR, PLR, RDW, CRP, and direct and total bilirubin levels can be used to determine the complications in appendicitis.
