Posterior resection of selected rectal tumors

Area of Science:

• Gastroenterology
• Surgical Oncology

Background:

• Villous adenoma is a rare rectal tumor.
• Large villous adenomas with wide bases present treatment challenges.

Purpose of the Study:

• To evaluate the safety and efficacy of posterior local excision for large rectal villous adenomas.

Main Methods:

• Seven patients with large rectal villous adenomas and one with adenocarcinoma underwent posterior local excision.
• Patients were observed for an average of 36 months.

Main Results:

• No deaths or major complications occurred; one patient developed a temporary fecal fistula.
• A local recurrence of benign villous adenoma was observed in one patient after 47 months.
• Posterior resection was simple and well-tolerated.

Conclusions:

• Posterior local excision is a viable and safe treatment for large rectal villous adenomas.
• This technique is not recommended for rectal adenocarcinoma when radical surgery is feasible.
