Area of Science:

  • Oncology
  • Surgical Oncology
  • Rectal Cancer Surgery

Background:

  • Lower rectal cancer treatment requires balancing oncologic control with functional preservation.
  • Nerve-sparing techniques aim to minimize postoperative morbidity, particularly urinary and sexual dysfunction.

Purpose of the Study:

  • To analyze survival, functional outcomes, operative challenges, and recurrence patterns in patients undergoing nerve-sparing surgery with lateral dissection for lower rectal cancer.

Main Methods:

  • Retrospective analysis of 133 patients who underwent nerve-sparing surgery with lateral dissection.
  • Evaluation of survival rates (5-year), urinary function, operative time, blood loss, and recurrence patterns.

Main Results:

  • Acceptable urinary function preserved in 84% of patients.

  • 5-year survival rates: 67% overall, 88% (Dukes' A), 74% (Dukes' B), 59% (Dukes' C).
  • Local recurrence rates: 2.7% (Dukes' B), 13% (Dukes' C).

    • Conclusions:

    • Pelvic nerve-sparing procedures with lateral dissection represent a promising surgical approach for lower rectal cancer.
    • This technique effectively achieves adequate lymphadenectomy while preserving crucial urinary function.
