| Abstract |
[Purpose]: Only a few reports about pediatric pyogenic lymphadenitis have been written by pediatric surgeons. We retrospectively examined the cases of this disease in our hospital. [Methods]: Patients with a white blood cell count >-8,000/μl and abscess formation on imaging between January 2008 and March 2020 were included. We collected information on the patients' background characteristics, laboratory findings, and course of treatment from medical records. We also compared the incisional drainage group and the non-incisional group and examined the correlation between abscess diameter and the duration of antimicrobial use. [Results]: Thirty-one patients (21 boys and 10 girls) were included in this study, and the age at initial examination was 3.66 +- 2.65 years. The sites of abscess formation were the neck in 25 patients, the axilla in one patient, and the inguinal region in five patients; pyogenic lymphadenitis was unilateral in 25 patients and bilateral in six. The abscess diameter at initial examination was 23.3 +- 7.8 mm, and there was a negative correlation between age and abscess diameter. Drainage was performed in 14 patients, and the number of days to drainage was 6.2 +- 5.9 days counting from the day of the initial examination. MSSA was detected by culture in 10 patients and MRSA was detected by culture in one patient, and neither MSSA nor MRSA was detected in three patients. The patients in the drainage group were younger and their abscess diameters were larger than those in the non-drainage group. The durations of hospitalization and antimicrobial use were longer in the drainage group. There was a significant negative correlation between abscess diameter and duration of antimicrobial use only in the drainage group. [Conclusions]: In pediatric pyogenic lymphadenitis, the younger the age, the larger the abscess diameter at the initial diagnosis. In the drainage group, the larger the abscess diameter, the shorter the duration of antimicrobial use. Further studies are needed to select the appropriate antimicrobial agents and determine the indications for incisional drainage. |
