Summary

Rectal cancer surgery can be improved by sphincter-preserving techniques and autonomic nerve preservation (ANP) to reduce postoperative morbidities like defecation, urinary, and sexual dysfunction. These advanced surgical methods enhance both cancer survival rates and functional outcomes for patients.

Area of Science:

  • Surgical Oncology
  • Gastrointestinal Surgery
  • Oncology

Context:

  • Rectal cancer surgery frequently leads to postoperative morbidities, including defecation, urinary, and sexual dysfunction.
  • Balancing effective cancer eradication with functional preservation is a key challenge in rectal cancer surgery.
  • Advancements in surgical techniques and instrumentation have improved outcomes.

Purpose:

  • To evaluate the efficacy of sphincter-preserving operations and autonomic nerve preserving (ANP) techniques in rectal cancer surgery.
  • To compare functional outcomes and survival rates between conventional and advanced surgical methods.
  • To discuss the role of local excision for early-stage rectal cancers.

Summary:

  • Sphincter-preserving operations like anterior resection, invagination, and pull-through have shown varying 5-year survival rates (81%, 71%, 57% respectively).

  • Autonomic nerve preserving (ANP) operations significantly reduced postoperative urinary dysfunction (15% vs. 33%) and male sexual impotence (21% vs. 81%) compared to conventional methods.
  • Local excision is a viable option for early rectal cancers confined to the mucosa or submucosa.

    • Impact:

    • Improved functional outcomes, including reduced rates of defecation, urinary, and sexual dysfunction after rectal cancer surgery.
    • Enhanced quality of life for rectal cancer patients through organ preservation.
    • Increased feasibility of sphincter preservation in over 65% of rectal cancer cases due to improved instrumentation.
