Robotic Intracorporeal Single-Stapled Anastomosis (RiSSA): Indications, Technical Benefits, and Current Limitations.
Review in The international journal of medical robotics + computer assisted surgery : MRCAS, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRobotic 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.
methodsA 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'.
resultsRiSSA 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.
conclusionsAvailable 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.
