TEO-Transanal Intersphincteric Intramesorectal and Laparoscopic Approach in Proctosigmoidectomy for Benign Disease

Completion proctectomy is the traditional approach in the rectal stump remaining after subtotal colectomy for benign disease. It is associated with high morbidity and urinary and sexual dysfunction. To reduce this risk, a minimally invasive approach is presented, intersphincteric intramesorectal proctosigmoidectomy by transanal endoscopic operation and laparoscopy.

Patients who had undergone total or subtotal colectomy for benign disease, those with a rectosigmoid stump who had rejected intestinal reconstruction and with refractory symptoms or risk of degeneration were selected. The technique proposed and the morbidity outcomes are described.

Three patients underwent this minimally invasive approach, operative time was 130 to 150 minutes. The median postoperative hospital stay was 6.6 days. Genitourinary and sexual tests performed in the male patient showed no dysfunction.

This minimally invasive technique, with intersphincteric resection and dissection close to the rectal wall, theoretically reduces morbidity and the damage to the autonomic pelvic nerves.
