Abstract

Background

Robotic surgery has significantly advanced colorectal procedures, yet achieving an optimal anastomotic technique remains challenging. The Robotic Intracorporeal Single-Stapled Anastomosis (RiSSA) has been introduced to overcome the limitations of the conventional double-stapled approach, such as intersecting staple lines and ‘dog ears’, which are potential structural weak points.

Methods

A comprehensive search of PubMed, Embase, Scopus, and Web of Science was performed through March 2026 using the keywords ‘robotic colorectal anastomosis’, ‘robotic single-stapled anastomosis’, and ‘RiSSA’.

Results

RiSSA was reviewed from its origin to recent applications, focussing on its technical rationale, procedural steps, and indications, including colorectal cancer, inflammatory bowel disease, and gynaecological conditions such as deep endometriosis. Advantages and limitations were critically assessed.

Conclusions

Available evidence suggests that RiSSA is a feasible and promising technique; however, high-quality prospective studies are needed to better define its comparative benefits and its long-term oncological and functional outcomes.

机器人体内单钉吻合术（RiSSA）：适应症、技术优势和当前局限性。

背景：机器人手术已经显著地推进了结直肠手术，但实现最佳的吻合技术仍然具有挑战性。机器人体内单钉吻合术（RiSSA）已经被引入，以克服传统双钉方法的局限性，例如相交的钉线和“狗耳”，这是潜在的结构弱点。方法：使用关键词“机器人结直肠吻合术”、“机器人单钉吻合术”和“RiSSA”，综合检索PubMed、Embase、Scopus和Web of Science，检索截止到2026年3月。结果：RiSSA从其起源到最近的应用进行了回顾，重点介绍了其技术原理、程序步骤和适应症，包括结直肠癌、炎症性肠病和妇科疾病，如深部子宫内膜异位症。对优势和局限性进行了批判性评估。结论：现有证据表明，RiSSA是一种可行且有前景的技术；然而，需要高质量的前瞻性研究来更好地确定其比较效益及其长期肿瘤和功能结果。

期刊介绍： The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
