Anterior resection syndrome significantly impacts quality of life for rectal cancer patients after sphincter-preserving surgery. This review explores its mechanisms and treatment options.

Area of Science:

  • Colorectal Surgery
  • Gastroenterology
  • Oncology

Background:

  • Sphincter-preserving surgery is common for rectal cancer, with up to 80% of patients undergoing this procedure.
  • A significant majority (up to 90%) of these patients experience altered bowel habits, including incontinence and dysfunction.
  • This constellation of symptoms is known as anterior resection syndrome (ARS), lacking a clear definition or established cause.

Purpose of the Study:

  • To investigate the underlying mechanisms contributing to disturbed bowel function after rectal cancer surgery.
  • To review current, emerging, and potential future therapeutic strategies for anterior resection syndrome.
  • To provide a comprehensive overview beyond comparative reconstructive techniques.

Main Methods:

  • Literature review focusing on mechanisms of bowel dysfunction post-rectal resection.

  • Analysis of current and novel treatment modalities for anterior resection syndrome.
  • Exploration of future research directions in managing ARS.

    • Main Results:

    • Anterior resection syndrome encompasses a range of bowel dysfunctions affecting quality of life.
    • Existing research often focuses on surgical reconstruction, but mechanisms of ARS are not fully understood.
    • A spectrum of treatments, from conservative to innovative, are being explored.

    Conclusions:

    • Understanding the mechanisms of anterior resection syndrome is crucial for effective management.
    • A multidisciplinary approach is likely needed to address the complex symptoms of ARS.
    • Further research into novel treatments is essential to improve patient outcomes and quality of life.
