Abstract

Objective

The incidence of recurrent peritonsillar abscess (7.4–22%) was estimated in retrospective studies. The aim of this prospective study was to estimate the cumulative incidence of recurrent peritonsillar abscess and related risk factors.

Methods

We performed a prospective longitudinal cohort study. The study included adult patients (≥18 years old) of both sexes who were attended in the emergency facilities of our tertiary hospital, without peritonsillar abscess background, diagnosed of a first episode of peritonsillar abscess and treated with standard of care (abscess drainage and antibiotics). Patients were followed for 24 months. Cumulative incidence of peritonsillar abscess recurrence was estimated and its 95% confidence interval was calculated; and predictive risk factors were assessed.

Results

Between January 1st, 2019 and March 9th, 2020, a total of 181 consecutive patients were included. The cumulative incidence of recurrent peritonsillar abscess at 2 years of the diagnosis was 9.9% (18 out of 181, 95% CI: 6.4–15.2%). The only risk factor associated with recurrent peritonsillar abscess in multivariate analysis was low plasma glucose level at the time of emergency room attendance (HR: 0.46, 95% CI: 0.24–0.91, p-value: 0.026).

Conclusion

Peritonsillar abscess is an incident medical issue, with an established recurrence rate, but with unclear predictive risk factors of recurrence. Further studies are needed to assess the risk factor associated with recurrent peritonsillar abscess.

成人复发性腹股沟周围脓肿:前瞻性纵向队列中的发病率和风险因素
目的 回顾性研究估计了复发性腹腔镜周围脓肿的发病率(7.4%-22%)。本前瞻性研究旨在估算复发性腹腔镜周围脓肿的累积发病率及相关风险因素。研究对象包括在我院三级医院急诊设施就诊的成年男女患者(≥18 岁),他们均无腹腔镜脓肿背景,被诊断为首次腹腔镜脓肿并接受了标准护理(脓肿引流和抗生素)。对患者进行了 24 个月的随访。结果在2019年1月1日至2020年3月9日期间,共纳入了181名连续患者。确诊2年后,腹腔镜周围脓肿复发的累计发生率为9.9%(181例中有18例,95% CI:6.4-15.2%)。在多变量分析中,唯一与腹腔周围脓肿复发相关的风险因素是急诊就诊时血浆葡萄糖水平低(HR:0.46,95% CI:0.24-0.91,P 值:0.026)。需要进一步研究来评估与腹腔镜周围脓肿复发相关的风险因素。
