Abstract
The technique of intersphincteric resection (ISR) has been proposed as an alternative to conventional abdominoperineal resection (APR) in low rectal cancer, in order to preserve the bowel continuity [1]. By definition, ISR means excision of part of or the whole of the internal anal sphincter by a combined abdominal and perianal approach [2]. Excision of the internal anal sphincter is performed to achieve safe distal resection margin in tumours close to or reaching the anal sphincter. Indications of ISR are therefore tumours with a lower edge less than 1 cm from the anal sphincter. Contraindications to ISR are infiltration of the external anal sphincter or the levator ani muscles and anal incontinence.
