Abstract：
OBJECTIVE: Peritonsillar abscess (PTA) is a frequent pathology. Treatment consists in drainage of the collection, associated to probabilistic antibiotic therapy. The usefulness of cytobacteriological testing (CBT) of the drainage pus is controversial.
METHODS: A retrospective study of patients managed for PTA between 2013 and 2020 in our university hospital was performed. The main objective was to assess the usefulness of CBT in the management of PTA. The secondary objectives were to determine the bacteriological profile involved in the onset of PTA and to assess the rate of bacterial resistance to antibiotics prescribed on a probabilistic basis.
RESULTS: The study included 207 patients: 70 outpatients (33%) and 137 inpatients (67%). Probabilistic antibiotic therapy was implemented in 100% of patients. CBT was performed systematically and was negative in 106 patients, revealing oropharyngeal flora in 40% of cases, polymicrobial flora in 50% and sterile samples in 10%. In the 101 patients with positive CBT, the bacteria isolated were penicillin-sensitive in 99%. All patients were successfully treated. In the light of the bacteriological results, no changes were made to the probabilistic antibiotic therapy introduced on admission.
CONCLUSIONS: CBT on drainage pus had no impact on the management of PTA. CBT is therefore unnecessary in patients with no comorbidities and no signs of severity at admission.

摘要：
目的：扁桃体周围脓肿（PTA）是一种常见的病理。处理包括收集的排水，与概率抗生素治疗相关。引流脓液的细胞细菌学测试（CBT）的有用性存在争议。
方法：对我院2013年至2020年接受PTA治疗的患者进行回顾性研究。主要目的是评估CBT在PTA管理中的有用性。次要目标是确定PTA发作所涉及的细菌学特征，并在概率基础上评估细菌对抗生素的耐药性。
结果：该研究包括207名患者：70名门诊患者（33%）和137名住院患者（67%）。100％的患者实施了概率抗生素治疗。系统进行CBT，106例患者为阴性，40%的病例显示口咽菌群，50％的微生物菌群和10％的无菌样品。101例CBT阳性患者中,99%的细菌对青霉素敏感。所有患者均成功治疗。根据细菌学结果，入院时采用的概率抗生素治疗没有变化.
结论：引流脓液的CBT对PTA的管理没有影响。因此，对于没有合并症且入院时没有严重迹象的患者，CBT是不必要的。
