Abstract
Extralevator abdominoperineal excision ELAPE was introduced to improve outcomes for lowlying locally advanced rectal cancers LARC not amenable to sphincter preserving procedures This study investigates prospectively outcomes of patients operated on with ELAPE compared with a similar cohort of patients operated on with conventional APEAfter the exclusion of patients without neoadjuvant therapy inhospital mortality and incomplete metastatectomy we identified 72 consecutive patients who had undergone either conventional APE n = 36 or ELAPE n = 36 for LARC ≤6 cm from the anal verge The primary outcome measure was local recurrence at 5 years and secondary outcome measures were causespecific and overall survivalMedian distance from the anal verge was significantly lower in the ELAPE group 2 vs 4 cm p = 0029 Inadvertent bowel perforation could be completely avoided in the ELAPE group but amounted to 167 in the conventional APE group p = 0025 Cumulative local recurrence rate at 5 years was 182 in the APE group compared to 59 in the ELAPE group p = 0153 Local recurrence without distant metastases occurred in 155 in the APE group but was not observed in the ELAPE group p = 0039 We did not detect significant differences in causespecific nor in overall survival
