Strategies for lateral pelvic lymph nodes

Gyu-Seog Choi
Choi argues for a selective, risk-adapted approach to lateral pelvic lymph nodes, using high-quality MRI to identify clinically suspicious nodes rather than treating all low rectal cancers with routine LPN dissection. For colorectal surgeons, the practical message is to integrate pre- and post-treatment MRI, response to neoadjuvant therapy, and the morbidity of LPN dissection when deciding which patients need an extended pelvic operation.
