Robotic transanal minimally invasive surgery (r-TAMIS): perioperative and short-term outcomes for local excision of rectal cancers

Transanal minimally invasive surgery (TAMIS) is an advanced technique for excision of early rectal cancers. Robotic TAMIS (r-TAMIS) has been introduced as technical improvement and potential alternative to total mesorectal excision (TME) in early rectal cancers and in frail patients. This study reports the perioperative and short-term oncological outcomes of r-TAMIS for local excision of early-stage rectal cancers. Retrospective analysis of a prospectively collected r-TAMIS database (July 2021–July 2023). Demographics, clinicopathological features, short-term outcomes, recurrences, and survival were investigated. Twenty patients were included. Median age and body mass index were 69.5 (62.0–77.7) years and 31.0 (21.0–36.5) kg/m2. Male sex was prevalent (n = 12, 60.0
