Abstract
急性闌尾炎在急診是相當常見的腹部急症, 由於其臨床的徵狀表現千變萬化, 因而常造成許多急診及外科醫師在確實診斷急性闌尾炎上的困難。 為了降低非必要的闌尾炎手術 ,因而發展出許多量表 (SCORING SYSTEM) 及發炎指標, 用來作為診斷急性闌尾炎評分系統的輔助工具。 其中最常被提及的檢查為白血球數目及C-反應蛋白 (CRP), 不僅於實驗室檢查的方便, 臨床使用的普及和實用性也相當高。 目前, 白血球數目及C-反應蛋白之升高常被應用在急性闌尾炎之診斷。 然而, 這是否意味著白血球數目及C-反應蛋白之升高就可作為急性闌尾炎之診斷? 其實, 許多文獻報告的結果都不盡相同。 從民國87年至90年, 本研究報告共收集420位診斷為急性闌尾炎且經手術切除闌尾之病患; 每位病患手術前都採集血液標本並測定其白血球數目及C-反應蛋白。 手術切除之闌尾標本也經病理檢查確認, 並且依據病理分類把病患分成3組, 即 GROUP A 非闌尾炎組149人, GROUP B 急性闌尾炎組202人, 及 GROUP C 急性壞疽性闌尾炎組69人, 並將每組白血球數目及C-反應蛋白之平均值分別作統計上之比較。 Group A 非闌尾炎組白血球數目及C-反應蛋白之平均值在正負標準差 WBC (13967/μl ± 5334), CRP (3.67mg/dl ± 4.93), Group B 急性闌尾炎組白血球數目及C-反應蛋白之平均值在正負標準差 WBC (14803/μl ± 4381), CRP (3.99mg/dl ± 6.41), Group C 急性壞疽性闌尾炎組白血球數目及C-反應蛋白之平均值在正負標準差 WBC (15068/μl ± 3423), CRP (4.99mg/dl ± 3.77)。 每組間之白血球及C-反應蛋白平均值, 經t檢定沒有統計上之意義。 因此, 臨床上, 白血球數目及C-反應蛋白之升高無法作為用於診斷急性闌尾炎之指標, 其所扮演的角色需再探討。
ABSTRACT PURPOSE: The aim of this research was to study the role and important of leucocyte count and C-reactive protein in clinical suspicious of acute appendicitis. METHODS: We performed a retrospective study of 420 cases, which underwent operation under the impression of acute appendicitis by clinical data and with a mean age of 34.12 years. The diagnosis of acute appendicitis was confirmed by pathology of the removed appendix vermiformis. According the pathological reports, it was divided into three groups: (Group A) uninflamed appendix vermiformis (n=149), (Group B) simple acute appendicitis (n=202), and (Group C) acute gangrenous appendicitis (n=69). Each group was compared by mean values of leucocyte count and C-reactive protein by using two-sided Student’s t-test. RESULT: The mean values and standard deviation of leucocyte count and C-reactive protein in each group are: Group A WBC (13967/μl ± 5334), CRP (3.67mg/dl ± 4.93), Group B WBC (14803/μl ± 4381), CRP (3.99 mg/dl ± 6.41), and Group C WBC (15068/μl ± 3423), CRP (4.99 mg/dl ± 3.77). The leucocyte count and C-reactive protein increase in simple acute appendicitis, and acute gangrenous appendicitis group but not significant when compare to the uninflamed appendix group by using Student’s t-test. CONCLUSION: Leucocyte count and C-reactive protein are not a good inflammatory serum marker for clinical suspicious of acute appendicitis. Neither normal nor increase in leucocyte count and C-reactive protein could suggest the possibility of acute appendicitis.
