摘要

This systematic review synthesizes current evidence on robotic transanal minimally invasive surgery (TAMIS) for rectal neoplasms, analyzing data from 26 clinical studies (2011–2024) involving 1,284 patients. The findings demonstrate robust short-term oncologic outcomes, including an 89.1% R0 resection rate for malignant lesions and an 8.3% local recurrence rate at a median follow-up of 28 months. Technical advancements, particularly the development of single-port robotic systems, have yielded significant improvements in procedural efficiency, reducing operative time by 22% while enhancing surgical ergonomics. Comparative analyses reveal advantages over conventional endoscopic TAMIS, including lower conversion rates (4% vs. 12%) and superior maneuverability in confined spaces. However, the review identifies persistent knowledge gaps regarding long-term survival outcomes and cost-effectiveness that require further investigation through prospective trials. The current evidence supports selective use of robotic TAMIS in specialized centers for carefully selected cases, particularly early-stage adenocarcinomas and complex benign lesions, while highlighting the need for standardized training protocols and economic evaluations.
