Sphincter-preserving surgery for rectal cancer offers benefits but often leads to bowel dysfunction. Understanding the anatomical, nerve, and sphincter changes is key to managing this common complication.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Colorectal Surgery
Context:
- Advancements in rectal cancer treatment have increased sphincter-preservation rates.
- Bowel dysfunction remains a significant challenge for patients post-sphincter-preserving surgery.
Purpose:
- To summarize the mechanisms and epidemiology of bowel dysfunction after rectal cancer surgery.
- To elucidate the role of these mechanisms in the treatment and prevention of bowel dysfunction.
Summary:
- Postoperative bowel dysfunction is linked to anatomical changes, nerve damage, and sphincter injury.
- Defecation function alterations are analyzed through anatomy, physiology, and dynamics.
- This review consolidates understanding of the causes and management strategies for bowel dysfunction.
Impact:
- Improved patient outcomes through better management of bowel dysfunction.
- Informed clinical decision-making for rectal cancer surgical approaches.
- Enhanced quality of life for patients undergoing rectal cancer treatment.
