Evaluation of the frequency and pattern of local recurrence following intersphincteric resection for ultra-low rectal cancer

Abstract EN

Introduction : Abdomino-perineal resection has been the standard treatment for rectal tumors located 65 cm from the anal verge.

Recently, intersphincteric resection became a valid option which preserves the bowel continuity with better functional outcome.

Aim : Is to evaluate the oncological and functional outcome alongside the associated surgical morbidity in patients with T1-3 rectal cancer, who underwent intersphincteric resection (ISR).

Patients & methods : Between the years 2006 and 2011, 55 patients with invasive rectal adenocarcinoma, T1-3 lesions, located 2–5 cm from the anal verge underwent ISR with total mesorectal excision.

When inevitable, complete.

ISR was performed, otherwise partial ISR was done.

All T3 patients underwent total meso-rectal excision (TME) while some had lateral lymph node dissection (LND) with concomitant pelvic autonomic nerve preservation (PANP).

Results : Among the 55 patients, 21 (38.1 %) patients were T1-2 and 34 (61.9 %) patients were T3.

The tumor location range was 0–5 cm from the anal verge (median 2.3 cm).

Partial or complete ISR
