Towards Standardisation of Technique for En Bloc Sacrectomy for Locally Advanced and Recurrent Rectal Cancer

Treatment strategies for advanced or recurrent rectal cancer have evolved such that the ultimate surgical goal to achieve a cure is complete pathological clearance. To achieve this where the sacrum is involved, en bloc sacrectomy is the current standard of care. Sacral resection is technically challenging and has been described; however, the technique has yet to be streamlined across units. This comprehensive review aims to outline the surgical approach to en bloc sacrectomy for locally advanced or recurrent rectal cancer, with standardisation of the operative steps of the procedure and to discuss options that enhance the technique.

Reconstruction after Subtotal Sacrectomy for Sacral Ewing’s Sarcoma Using Tibial Allograft Strut Grafting: A Case Report

We present the case of a 15-year-old girl. Two months after becoming aware of pain, she was diagnosed with a sacral tumor and referred to our department. She was diagnosed with a sacral Ewing’s sarcoma; after chemotherapy, it was determined that the tumor could be resected, so surgical treatment was performed. The sacrum and ilium were partially resected at the lower end of S1, and the lumbar vertebrae and pelvis were fixed with a pedicle screw and two iliac screws on each side of L3, and the sacral resection was reconstructed with a tibial strut allograft. No tumor recurrence or metastasis has been observed 1 year postoperatively. She developed bladder and rectal dysfunction, but she remained independent in activities of daily living and her daily life was not limited. The bone fusion in the reconstructed area confirmed the lack of instrumentation looseness. Surgical treatment for sacral Ewing’s sarcoma was performed to cure the patient. We believe that the tibial allograft contributed to the patient’s ability to walk on her own due to its high mechanical stability. Postoperative bone healing was observed with the same material, suggesting that the tibial allograft is useful for similar procedures.

A minimally invasive pericoccygeal approach to resection of a large presacral schwannoma: case report

Resection of large presacral schwannomas can present a challenge. The posterior approach is commonly associated with coccygeal disarticulation, partial sacral resection, and muscular disarticulation, which can all result in significant morbidity. Minimally invasive surgery may obviate some of the morbidity traditionally associated with this approach. The authors present the case of a morbidly obese 49-year-old man with an enlarging presacral schwannoma. The patient refused laparoscopic resection because of the morbidity he had experienced with a previous laparoscopic surgery. The tumor was resected using a minimally invasive paracoccygeal approach, which affords improved access with minimal morbidity.
