Unplanned excision of soft tissue sarcomas of the musculoskeletal system. / Resección no planificada en sarcomas de partes blandas del aparato locomotor.

INTRODUCTION: The diagnosis process of soft tissue sarcomas of the musculoskeletal system (SPBAL) continues to be complex, with cases of unplanned excisions ("whoops" surgeries). This study evaluates the frequency of these type of procedures, trying to indentify patient characteristics, tumors, surgical treatment and final results. MATERIAL AND METHODS: 131 patients treated surgically between October 2018 and December 2021 of a SPBAL were retrospectively reviewed. Patients with SPBAL located in the viscera, mediastinum, heart, retroperitoneum, peritoneum and genital tract were excluded. Differences between patients with planned and unplanned excisions were assessed with chi2 tests and a Cox multivariate regression model. RESULTS: Unplanned excisions of SPBAL have taken place in 18% of the patients in our área, mainly in tumors of less than 5 cm and located superficial to the fascia. 29,2% of these patients did not have a previous imaging test. It has not been shown that a "whoops" surgery can lead to a decrease in survival or a higher rate of recurrences. CONCLUSIONS: We recommend carrying out an imaging test always prior to the removal of any type of soft tissue tumor, as well as adherence to the referral guidelines to reference centers.

Resección no planificada en sarcomas de partes blandas del aparato locomotor / Unplanned excision of soft tissue sarcomas of the musculoskeletal system

Introducción: El proceso diagnóstico de los sarcomas de partes blandas del aparato locomotor (SPBAL) sigue siendo comprometido, con casos de resecciones no planificadas (cirugías «whoops»). Este estudio evalúa la frecuencia de este tipo de procedimientos, tratando de identificar características de los pacientes, tumores, tratamiento quirúrgico y resultados. Material y métodos: Se revisan de forma retrospectiva 131 pacientes tratados de forma quirúrgica en nuestro centro entre octubre de 2018 y diciembre de 2021 de un SPBAL. Se excluyen los pacientes con SPBAL localizados en vísceras, mediastino, corazón, retroperitoneo, peritoneo y aparato genital. Las diferencias entre pacientes con resecciones planificadas y no planificadas fueron evaluadas con pruebas χ2 y un modelo de regresión multivariado de Cox. Resultados: Las resecciones no planificadas de SPBAL han tenido lugar en 18% de los pacientes de nuestra área, principalmente en tumores menos de 5 cm y localizados superficiales a la fascia; 29,2% de estos pacientes no disponían de una prueba de imagen previa. No se ha demostrado que una cirugía «whoops» pueda suponer una disminución de la supervivencia o una mayor tasa de recidivas. Conclusiones: Recomendamos la realización de una prueba de imagen siempre previa a la extirpación de cualquier tipo de tumoración de tejidos blandos, así como la adherencia a las guías de remisión a centros de referencia.(AU)

Edema persistente de miembro inferior debido a quistes sinoviales en un paciente con artritis reumatoide / Persistent lower limb edema caused by synovial cysts in a patient with rheumatoid arthritis

Introducción. Las bursitis del iliopsoas son una entidad clínica poco frecuente como causa de compresión de estructuras vasculonerviosas de la región inguinal. Ésta a menudo se encuadra asociada a diversas patologías de la cadera y es raro encontrarla como entidad clínica aislada. Caso clínico. Se presenta el caso de un paciente de 75 años diagnosticado de artritis reumatoide de larga evolución, con edemas persistentes en miembro inferior derecho, así como dolor e incapacidad funcional de la misma cadera debido a una amplia sinovitis. Los estudios de imagen demuestran un quiste sinovial ectópico gigante del iliopsoas con compresión de las estructuras vasculares inguinales. Fue tratado, en principio, con punciones repetidas e infiltraciones de corticoides que no resolvieron el caso, por lo que se decide extirparlo quirúrgicamente, para en un segundo tiempo proceder a la sustitución total de la cadera. Conclusión. Los autores concluyen que la bursitis del iliopsoas debe ser considerada en la evaluación de los pacientes con dolor inespecífico de la ingle o la pelvis. El tratamiento con corticoides se debería intentar como alternativa previa a la cirugía

Introduction. Bursitis of the iliopsoas infrequently causes compression of the vascular and nerve bundle in the inguinal region. Compression of vascular and nerve structures in the inguinal region is more frequently associated with different hip conditions and is rarely found as an isolated clinical entity. Case report. We present the case of a 75 year old patient diagnosed with long term rheumatoid arthritis and persistent edema in his lower right leg. The patient also reported pain and had decreased functionality of his right hip due to a large synovitis. Images showed a giant ectopic synovial cyst on the iliopsoas with compression of inguinal vascular structures. The patient was initially treated with repeated punctures and steroid injections, but did not resolve. Therefore it was decided to excise the cyst surgically and subsequently, in a second operation, perform total hip replacement. Conclusion. The authors conclude that iliopsoas bursitis must be considered when patients with non-specific pain in the groin or pelvis are assessed. Steroid treatment must be used before deciding on a surgical approach
