OBJECTIVE: Local recurrence after abdomino-perineal excision of the rectum for tumours has been reported to occur in up to a third of patients in contrast to 4% after restorative anterior resection. METHOD: Low rectal tumours were defined as tumours within 8 cm of the anal verge and were treated by either stapled low anterior resection (SLAR) or abdomino-perineal excision of the rectum (APER). One hundred and seventy-eight patients with tumours in the lower third of the rectum (30% of 591 rectal cancers) underwent surgical resection between 1980 and 2001. Data were collected prospectively; 68 (38%) had SLAR and 110 (62%) had APER with median follow up of approximately 12 years; 54 SLAR (79%) and 76 APER (69%) had curative procedures on clinical and pathological criteria. RESULTS: Local and distant recurrence occurred in seven (13%) and eight (15%) patients in the SLAR group and six (8%) and 14 (18%) patients in the APER group, respectively. Overall 5-year survival was 63% and 60% in the SLAR and APER groups, respectively CONCLUSION: For rectal cancers within 8 cm of the anal verge, both procedures achieved equivalent results measured by low local recurrence rates and overall survival.
