Manejo endoscópico del atrapamiento del nervio ciático en el síndrome de glúteo profundo: resultados clínicos / Endoscopic treatment of sciatic nerve entrapment in deep gluteal syndrome: Clinical results

Introducción: El síndrome de glúteo profundo (SGP) es una enfermedad caracterizada por la compresión a nivel extra-pélvico del nervio ciático (NC) por cualquier estructura en el espacio glúteo profundo. El objetivo de este estudio fue evaluar los resultados clínicos en pacientes con SGP manejados con técnica endoscópica. Métodos: Estudio retrospectivo de pacientes con SGP intervenidos con técnica endoscópica entre 2012 al 2016 con seguimiento mínimo de 12 meses. Los pacientes fueron evaluados antes de la intervención y durante el primer año de seguimiento con las escalas WOMAC y VAIL. Resultados: Se incluyeron 44 cirugías en 41 pacientes (36 mujeres y 5 varones) con un promedio de edad de 48,4±14,5 años. La causa más frecuente de atrapamiento fueron las bandas fibrovasculares, hubo 2 casos de variante anatómica en la salida del nervio, y en un caso aislado, el atrapamiento del NC fue atribuido a la aplicación de biopolímeros en la región glútea. Se encontró mejoría de la funcionalidad y dolor valorado con la escala WOMAC con una mediana de 63 a 26 puntos después de la intervención (p<0,05). Al final del seguimiento un paciente continuaba con dolor residual del nervio cutáneo femoral posterior. Cuatro casos requirieron de revisión a los 6 meses posteriores al procedimiento, por atrapamiento de tejido de cicatrización alrededor del NC. Conclusión: La liberación endoscópica del NC es una alternativa en el manejo del SGP al mejorar la función y disminuir el grado de dolor, cuando existe una adecuada selección de pacientes

Introduction: Deep gluteal syndrome (DGS) is characterized by compression, at extra-pelvic level, of the sciatic nerve within any structure of the deep gluteal space. The objective was to evaluate the clinical results in patients with DGS treated with endoscopic technique. Methods: Retrospective study of patients with DGS treated with an endoscopic technique between 2012 and 2016 with a minimum follow-up of 12 months. The patients were evaluated before the procedure and during the first year of follow-up with the WOMAC and VAIL scale. Results: Forty-four operations on 41 patients (36 women and 5 men) were included with an average age of 48.4±14.5. The most common cause of nerve compression was fibrovascular bands. There were two cases of anatomic variant at the exit of the nerve; compression of the sciatic nerve was associated with the use of biopolymers in the gluteal region in an isolated case. The results showed an improvement of functionality and pain measured with the WOMAC scale with a mean of 63 to 26 points after the procedure (P<.05). However, at the end of the follow-up one patient continued to manifest residual pain of the posterior cutaneous femoral nerve. Four cases required revision at 6 months following the procedure due to compression of the scarred tissue surrounding the sciatic nerve. Conclusion: Endoscopic release of the sciatic nerve offers an alternative in the management of DGS by improving functionality and reducing pain levels in appropriately selected patients
