[Posterior rectotomy indications for villous tumors]

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Gastroenterology

Context:

• Villous tumors of the rectum pose surgical challenges.
• Traditional removal methods may have limitations for certain tumor sizes and locations.
• The Kraske approach offers an alternative surgical technique.

Purpose:

• To evaluate the safety and efficacy of the posterior (Kraske) approach for rectal villous tumors.
• To assess complication rates and outcomes associated with this surgical method.

Summary:

• The posterior (Kraske) approach was utilized in 12 patients for rectal villous tumor excision.
• Postoperative complications included wound infection, hemorrhage, dehiscence, and cellulitis in six patients.
• One patient experienced mortality; however, no fistulas were observed.
• This approach is well-tolerated, especially in elderly patients and for mid-rectal lesions unsuitable for other methods.
• The procedure is indicated for benign tumors, with preoperative digital palpation aiding diagnosis, though microscopic confirmation is essential.

Impact:

• The posterior approach provides a viable surgical option for specific rectal villous tumors.
• It demonstrates a low rate of fistula formation, a significant advantage.
• The technique is particularly beneficial for high-risk patients and challenging tumor locations.
