Major sacral resection outcomes were studied in 53 patients. Preserving sacral nerves, especially S3 roots, is key for maintaining bowel and bladder function after surgery.

Area of Science:

  • Oncology
  • Neurosurgery
  • Urology

Background:

  • Major sacral resection is typically for malignant tumors.
  • Outcomes, particularly bowel and bladder function, are poorly understood due to rarity.

Purpose of the Study:

  • To retrospectively analyze bowel and bladder function after major sacral resection.
  • To identify factors influencing functional outcomes.

Main Methods:

  • Retrospective analysis of 53 patients undergoing major sacral resection over 10 years.
  • Evaluation of bowel and bladder function based on the extent of sacral nerve root resection.

Main Results:

  • Unilateral sacrectomy with contralateral nerve preservation: 87% normal bowel, 89% normal bladder function.

  • Bilateral S2-S5 sacrifice: 100% abnormal bowel and bladder function.
  • Bilateral S3-S5 resection: 40% normal bowel, 25% normal bladder function.
  • Bilateral S4-S5 resection with S3 preservation: 100% normal bowel, 69% normal bladder function.
  • Asymmetric resection with at least one S3 nerve preserved: 67% normal bowel, 60% normal bladder function.

    • Conclusions:

    • Unilateral sacral root resection preserves function in most patients.
    • Preserving at least one S3 nerve root during bilateral resection is critical for maintaining bowel and bladder function.
    • Surgical strategy should aim to preserve sacral nerve roots to optimize functional outcomes.
