[Colo-anal anastomosis. Our experience]

Area of Science:

• Oncology
• Surgical Gastroenterology
• Rectal Cancer Surgery

Context:

• Rectal cancer treatment, particularly ultra-low tumors, presents challenges in preserving sphincter and sexual functions.
• Anterior resection with colo-anal anastomosis is a surgical approach for managing these complex cases.
• Locoregional recurrence remains a concern in rectal cancer management.

Purpose:

• To present the surgical outcomes and experiences with ultra-low rectal carcinomas treated via anterior resection and colo-anal anastomosis.
• To evaluate the efficacy of this surgical technique in managing rectal cancer.
• To assess functional outcomes (sphincter, sexual) and recurrence rates.

Summary:

• Thirty-three patients with low and ultra-low rectal carcinoma underwent surgery between 2005 and 2007.
• The majority (30 patients) received neoadjuvant radio-chemotherapy prior to surgery.
• Surgical procedures included colo-anal anastomosis (16 patients), ultra-low colorectal anastomosis (11 patients), and Miles resection (7 patients).

Impact:

• This experience contributes to understanding the feasibility and outcomes of ultra-low rectal cancer surgery.
• The results may inform surgical decision-making for rectal cancer, balancing oncological control with functional preservation.
• Updated results provide valuable data for optimizing treatment strategies and patient care in rectal cancer surgery.
