Summary
The Robotic Intracorporeal Single-Stapled Anastomosis (RiSSA) offers a promising alternative for robotic colorectal surgery, potentially improving upon traditional methods. Further high-quality studies are needed to confirm its long-term benefits.
Area of Science:
- Minimally Invasive Surgery
- Surgical Technology
- Gastrointestinal Surgery
Background:
- Robotic surgery enhances colorectal procedures, but anastomotic techniques present challenges.
- The Robotic Intracorporeal Single-Stapled Anastomosis (RiSSA) addresses limitations of double-stapled methods.
- Potential weak points like intersecting staple lines and 'dog ears' are mitigated by RiSSA.
Purpose of the Study:
- To review the origin, applications, and technical aspects of RiSSA.
- To critically assess the advantages and limitations of the RiSSA technique.
- To evaluate RiSSA's role in various colorectal and gynecological conditions.
Main Methods:
- Comprehensive literature search across major databases (PubMed, Embase, Scopus, Web of Science).
- Keywords included 'robotic colorectal anastomosis', 'robotic single-stapled anastomosis', and 'RiSSA'.
- Review conducted up to March 2026.
Main Results:
- RiSSA's technical rationale, procedural steps, and indications were analyzed.
- Applications span colorectal cancer, inflammatory bowel disease, and deep endometriosis.
- Advantages and limitations of RiSSA were critically evaluated.
Conclusions:
- RiSSA appears to be a feasible and promising surgical technique.
- High-quality prospective studies are required for definitive conclusions.
- Further research should focus on comparative benefits and long-term oncological/functional outcomes.
