Laparoscopic total mesorectal excision combined with en-bloc seminal vesicle and prostate resection for rectal cancer after chemoradiotherapy.

It is safe and feasible to perform laparoscopic TME combined with en-bloc SVR and PPR in selected LARC patients after neoadjuvant CRT. It can provide a safe circumferential resection margin and R0 resection. More studies are warranted to improve the diagnostic accuracy for T4b stage after CRT and avoid unnecessary extended resection.
