Abstract

Locally recurrent rectal cancer (LRRC) is a complex disease with far-reaching implications for the patient. Until recently, research was limited regarding surgical techniques that can increase the ability to perform an en bloc resection with negative margins. This has changed in recent years and therefore outcomes for these patients have improved. Novel radical techniques and adjuncts allow for more radical resections thereby improving the chance of negative resection margins and outcomes. In the past contraindications to surgery included anterior involvement of the pubic bone, sacral invasions above the level of S2/S3 and lateral pelvic wall involvement. However, current data suggests that previously unresectable cases may now be feasible with novel techniques, surgical approaches and reconstructive surgery. The publications to date have only reported small patient pools with the research conducted by highly specialised units. Moreover, the short and long-term oncological outcomes are currently under review. Therefore although surgical options for LRRC have expanded significantly, one should balance the treatment choices available against the morbidity associated with the procedure and select the right patient for it.

Core tip: This article provides an up-to-date review of the current international trends in surgical approaches for locally recurrent rectal cancer (LRRC), specifically highlighting the novel radical techniques that are now used in cases previously deemed unresectable. We have described these approaches according to anatomical locations of the recurrences and reviewed the respective oncological and functional outcomes. In addition, laparoscopic surgeries for LRRC are discussed and their outcomes are outlined.
