Institutional review board statement: This study was approved by our local institutional review board. Prior to April 2019, institutional board review approval was not required by our institution; data was prospectively collected and extracted from a database managed by our colorectal department coordinator using FileMaker© (Claris International Inc., United States of America) from January 2015. Data was de-identified when extracted for analysis with no traceable data or reference codes for re-identification of included patients. For data after April 2019, institutional review board approval was obtained for our prospectively maintained database. Data was stored on REDCap and de-identified by our colorectal department coordinator prior to analysis by the study team. The study team made no attempts to access patients' medical records.
Informed consent statement: Informed consent was obtained from patients included (No. SDB-2023-0069-TTSH-01).
Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article.
Data sharing statement: The data used in this study is not publicly available due to institutional policies. However, requests may be made to the corresponding author for access to de-identified data at kchan023@e.ntu.edu.sg.

Core Tip

Core Tip: Multivisceral resection (MVR) remains the only potential curative surgical treatment for locally advanced rectal cancer but bears high morbidity. Literature on minimally invasive MVR (miMVR) is scarce. Our results showed that miMVR had lower major morbidity and shorter length of stay compared to open MVR with comparable R0 resection and long-term survival. Robotic MVR was used for more complex cases but had similar post-operative complications compared to laparoscopic MVR. Use of robotic MVR is feasible and safe even in lower volume institutions for locally advanced rectal cancer.
