Intersphincter resection (ISR) is considered to be a superior technique offering sphincter preservation in patients with ultralow rectal cancer.1 Because high-definition laparoscopy offers wider and clearer vision into the narrow pelvic cavity and intersphincteric space, ISR has been further refined.2 However, functional outcome after ISR has not been optimal. More than half of patients receiving ISR suffer partial or even complete anal incontinence.3 We therefore propose a laparoscopic-assisted modified ISR, with the aim of improving sphincter function following ISR. ⋯ Laparoscopic-assisted modified intersphincter resection for ultralow rectal cancer is safe and feasible. This technique should be considered whenever possible as a means to offer sphincter preservation and improve sphincter function in patients with ultralow rectal cancer.
