    Summary

    Sphincter-saving rectal cancer surgery preserves anal, urinary, and sexual functions. Autonomic nerve preservation in early rectal cancer significantly reduces post-operative urinary and sexual dysfunction.

    Area of Science:

    • Oncology
    • Surgical Gastroenterology
    • Urology

    Context:

    • Rectal cancer treatment aims to maximize oncologic control while preserving critical functions.
    • Sphincter-saving procedures are increasingly utilized for upper and middle rectal cancers.
    • Understanding the impact of surgical techniques on functional outcomes is crucial.

    Purpose:

    • To evaluate the effectiveness of sphincter-saving operations in preserving anal, urinary, and sexual functions in rectal cancer patients.
    • To assess the role of autonomic nerve preservation in mitigating post-operative dysfunction.

    Summary:

    • Low anterior resection, invagination, and pull-through techniques are key sphincter-saving operations for upper and middle rectal cancers, treating over 60% of cases.
    • These procedures, when applied to Dukes A rectal cancer, involve anatomical preservation of autonomic nerves (hypogastric, pelvic, pudendal).
    • Successful autonomic nerve preservation leads to a significant reduction in post-operative urinary and male sexual dysfunction, with rates decreasing to 10% or less.

    Impact:

    • Establishes sphincter-saving surgery and autonomic nerve preservation as effective strategies for maintaining quality of life in rectal cancer survivors.
    • Provides evidence for improved functional outcomes, specifically urinary and sexual function, following tailored surgical approaches.
    • Highlights the importance of meticulous surgical technique in autonomic nerve preservation for rectal cancer surgery.
