[Colo-anal anastomosis, a strong competitor of preternatural anus]

Area of Science:

• Surgical Oncology
• Gastroenterology

Background:

• Colostomy after rectal amputation significantly impacts patient lifestyle.
• Restoring anal defecation after rectal extirpation is desirable if oncological safety and functional outcomes are maintained.

Purpose of the Study:

• To evaluate colo-anal anastomosis as an alternative to colostomy after rectal excision for low-seated lesions.
• To assess the method's safety, functional results, and oncological consequences.

Main Methods:

• Literature review and analysis of seven patient cases undergoing colo-anal anastomosis.
• Evaluation of complications, functional outcomes, and oncological principles.

Main Results:

• Colo-anal anastomosis is a viable alternative to colostomy in selected rectal cancer cases.
• The method demonstrated good functional results and adhered to oncological principles.
• It can be applied when low anterior resection is not feasible or technically more challenging.

Conclusions:

• Colo-anal anastomosis can successfully prevent the need for a colostomy.
• This technique offers a safe and effective option for selected rectal carcinoma patients, preserving quality of life.
