Background: Isolated seminal vesicle invasion is a rare occurrence in patients with locally advanced rectal cancers. This study describes the surgical technique and the perioperative outcomes of minimally invasive 'en‐bloc' seminal vesicle excision, preserving the bladder and the prostate. Methods: A retrospective review of 23 consecutive patients who underwent minimally invasive, en‐bloc resection of seminal vesicles for locally advanced, non‐metastatic rectal adenocarcinoma between May 2016 and November 2021. Perioperative outcomes and short‐term oncological outcomes were defined. Results: Eighteen patients underwent a laparoscopic procedure while five received a robotic resection. All patients received preoperative radiation with or without consolidation chemotherapy. The median age was 42 years (range 20–64 years) and the median hospital stay was 8 days (range 3–19 days), respectively. Serious complications (Clavien–Dindo ≥ IIIb) were seen in six patients (26.1%). Two patients (8.7%) had an involved circumferential resection margin. At a median follow up of 19 months (range 2–52 months), four patients developed recurrences. The 2‐year overall and disease‐free survival was 84.4% and 73.6%, respectively. Conclusion: Minimally invasive, en‐bloc resection of one or both seminal vesicles for locally advanced rectal adenocarcinoma, is feasible in a select group of patients with acceptable morbidity and short‐term outcomes.
