Our short-term results in patients who underwent sphincter-saving trans-sphincteric surgery by excising the invasive proximal sphincteric segment due to advanced lower rectal cancer with external anal sphincteric invasion

Key Points

• The study aims to evaluate the outcomes of sphincter-preserving surgery using trans-sphincteric methods for advanced lower rectal cancer.
• Evaluated patients who underwent trans-sphincteric surgery.
• Focused on excising the invasive proximal sphincteric segment.
• Considered patient outcomes related to surgical complications.
• Sphincter-preserving surgery was possible despite high complication rates.
• Trans-sphincteric techniques are viable alternatives for affected patients.
• The invasive proximal segment can be effectively resected.
