Abstract

Insights

Internal hemipelvectomy is a complex surgery for pelvic tumors. While complications occur, it offers better function and survival rates than external hemipelvectomy, especially with curative intent.

Area of Science:

  • Surgical Oncology
  • Orthopedic Surgery
  • Pelvic Reconstruction

Background:

  • Complications and long-term outcomes of internal hemipelvectomy are not well-documented.
  • Internal hemipelvectomy is a complex surgical procedure.

Purpose of the Study:

  • To document the complications and long-term follow-up results of internal hemipelvectomy.
  • To evaluate functional outcomes and survival rates associated with internal hemipelvectomy.

Main Methods:

  • Retrospective review of 32 internal hemipelvectomy cases performed between 1976 and 1994.
  • Analysis of pathological diagnoses, surgical approach, complications, functional status, and survival rates.

Main Results:

  • Common diagnoses included soft tissue sarcoma (15) and bone tumors (14).
  • Average blood loss was 3.2 L, and operative time averaged 7.5 hours.
  • Complications included infection (15 cases) and skin flap necrosis (4 cases). Functional outcomes showed 34% ambulated independently, 59% with crutches, and 7% wheelchair-bound.
  • Ten-year survival rates were 45% for curative resections versus 29% at two years for palliative resections.

Conclusions:

  • Internal hemipelvectomy is a complex procedure with significant morbidity but offers functional and cosmetic advantages over external hemipelvectomy.
  • Curative intent internal hemipelvectomy is associated with considerable long-term survival rates.
