扁桃腺切除術(shù)具有良好的療效 【?2007-05-30 發(fā)布?】 美迪醫(yī)訊
扁桃腺切除術(shù)對預防成人新發(fā)甲型鏈球菌感染來說是行之有效的治療手段。 Oulu (Finland)大學的科學家隨機抽取70例鏈球菌感染性咽炎病例(這些病例滿足6個月內(nèi)3次或更多或者1年內(nèi)有四次感染經(jīng)歷的病人)。這項研究目的為了檢測成人扁桃腺切除術(shù)的有效性。36例病人隨機抽樣后進行手術(shù),另外34例病人作為參照。原始結(jié)果以90天內(nèi)再發(fā)鏈球菌感染風險的百分比變化的形式表示。 結(jié)果顯示與對照組相比,扁桃腺切除術(shù)能迅速下降急性咽炎的發(fā)生次數(shù)。除了術(shù)后2周咽喉疼痛外沒有強烈的副作用。90天后,對照組中有8例(24%)再次發(fā)生鏈球菌性咽炎,而手術(shù)組中僅有1例(3%)再發(fā)這種疾病。對照組咽炎的平均再發(fā)次數(shù)為2.1次,而切除扁桃腺組為0.6次。與切除組相比,對照組咽炎發(fā)生時,咽喉以及發(fā)熱癥狀持續(xù)的時間要長得多,鼻炎的癥狀也更加嚴重。此研究刊登于英國醫(yī)學雜志2007年5月刊。 Oulu大學Pekka Alho博士認為,扁桃腺切除的即刻效應(yīng)反映這種做法對臨床上防止再發(fā)鏈球菌性咽喉感染是非常有用的。 來源:University of Oulu Tonsillectomy Found Effective in Adults Tonsillectomy is an effective remedy for adults with recurrent bouts of group A streptococcal pharyngitis, according to a new study. Researchers at the University of Oulu (Finland) enrolled 70 adults in a randomized prospective study of adults with recurrent streptococcal pharyngitis (defined as three or more episodes in six months or four episodes in a year). The study wished to examine the effectiveness of tonsillectomy in adults. Thirty-six patients were randomized to immediate surgery, and 34 remained on the waiting list as controls. The primary outcome was the percentage change in the risk of an episode of streptococcal pharyngitis at 90 days. The results showed that tonsillectomy sharply reduced the number of acute episodes of pharyngitis, compared with watchful waiting. There were no serious adverse effects other than about two weeks of throat pain after the surgery. At 90 days, streptococcal pharyngitis had recurred in eight of the control patients (24%). One patient (3%) in the tonsillectomy group had a recurrence. The mean number of medical consultations for pharyngitis was 0.9 in the control group and 0.1 in the tonsillectomy group. The mean number of episodes of pharyngitis was 2.1 in the control group and 0.6 in the tonsillectomy group. The controls also had significantly more days with sore throat and fever, and rhinitis was higher, but not significantly so. The study was published in the May 5, 2007 issue of the British Medical Journal (BMJ). "Traditionally, tonsillectomy has been used to prevent recurrent streptococcal throat infections,?concluded lead author Olli-Pekka Alho, M.D., Ph.D., from the University of Oulu, and colleagues. think that the immediate effect of tonsillectomy reflects its overall usefulness.?/td> Related Links: University of Oulu 本文關(guān)鍵字:
