Título

Ultrasound and Doppler in the Identification and Follow-up of Pilonidal Cysts in Pediatrics

Descrição sucinta do(s) objetivo(s)

To analyze ultrasound and Doppler findings in the detection and follow-up of pilonidal cysts in pediatric patients, highlighting their usefulness in identifying cysts, ensuring appropriate post-surgical follow-up, and detecting complications such as recurrences, infections, and fistulous tracts.

Material(is) e método(s)

A retrospective study was conducted on 55 pediatric patients diagnosed with pilonidal cysts, evaluated with ultrasound and Doppler (15 MHz). Ultrasound was used to locate the cysts, assess post-surgical changes, and detect complications, while Doppler was employed to analyze inflammatory activity in fistulous tracts.

Resultados e discussão

Of the 55 patients, 47 (85%) presented well-defined cysts located in the sacrococcygeal midline, with an average size of 3.2 cm (range 1.5-5.0 cm). Recurrences were detected in 6 (11%) patients, and infectious complications in 4 (7%).
Ultrasound identified fistulous tracts in 9 (16%) cases. Doppler showed increased vascularization in 5 (9%) cases, indicating active inflammation, and allowed differentiation between acute (increased flow) and chronic (low or no flow) processes.
Post-surgical follow-up using ultrasound was conducted in 42 (76%) patients, with no recurrences or complications. The remaining 24% required further intervention due to persistent fistulous tracts.

Conclusões

Ultrasound and Doppler are essential for the diagnosis and follow-up of pilonidal cysts in pediatrics. These tools provide accurate visualization of cysts, facilitate the detection of complications, and allow analysis of inflammatory activity, aiding in timely therapeutic decision-making.
