Spinopelvic Reconstruction with Femoral Allograft and Vertical Rectus Abdominis Myocutaneous Flap after Total Sacrectomy in Recurrent Sacral Chordoma: A Case Report

STUDY DESIGN: Case report. OBJECTIVES: To report a case of recurrent sacral chordoma treated with total sacrectomy and spinopelvic reconstruction. SUMMARY OF LITERATURE REVIEW: Sacral chordoma is a musculoskeletal tumor reported to have a low incidence. Surgical treatment is considered difficult due to the complicated sacropelvic structure, so the prognosis for patients with sacral chordoma has been considered poor. MATERIALS AND METHODS: We report a surgical technique and outcomes from spinopelvic reconstruction with femoral allograft and vertical rectus abdominis myocutaneous flap after total sacrectomy. RESULTS: We report no tumor recurrence at 43 months postoperatively. CONCLUSIONS: Spinopelvic reconstruction with thorough surgical planning after total sacrectomy was found to be a safe and effective treatment method.

Resección abdominoperineal isquioanal con reconstrucción de pared posterior de vagina con colgajo miocutáneo de músculo recto abdominal vertical / Ischioanal abdominoperineal resection with reconstruction of posterior wall of vagina with vertical rectus abdominis myocutaneous flap

El colgajo del recto abdominal miocutáneo vertical, es un excelente colgajo que rellena el gran defecto en la pelvis luego de una resección abdominoperineal isquioanal, siendo libre de tensión y reduciendo significativamente la incidencia de complicaciones de la herida perineal y la estancia hospitalaria, con el cual se puede reconstruir la pared posterior de la vagina. Se reporta aquí el primer caso en Costa Rica de una resección abdominoperineal isquioanal, con reconstrucción de pared posterior de vagina con colgajo del recto abdominal miocutáneo vertical, practicada con éxito en una paciente de 62 años, con un adenocarcinoma rectal localmente avanzado con infiltración de pared posterior de vagina.

Vertical rectus abdominis myocutaneous flap, is an excellent flap that fills the large defect in the pelvis after an adominoperineal ischioanal resection; it is free from tension, significantly reduces the incidence of perineal wound complications and hospital stay and can be used to reconstruct the posterior wall of the vagina. We report the first case of Costa Rica abdominoperineal ischioanal resection with reconstruction of posterior vaginal wall with vertical rectus abdominis myocutaneous flap, successfully practiced in a patient of 62 years with locally advanced rectal adenocarcinoma infiltrating posterior wall of the vagina.
