Comparative wound healing of intestinal anastomosis: high-frequency electric welding vs suture in a rabbit model.
Article in International journal of surgery (London, England), 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
backgroundThis study aimed to comparatively evaluate the tissue healing characteristics of High-Frequency Electric Welding (HFEW) versus conventional suture techniques in intestinal side-to-side anastomosis using an animal model. MATERIALS AND
methodsIntestinal side-to-side anastomoses were performed in New Zealand White rabbits using HFEW and hand-sewn techniques. Intraoperative assessment focused on procedure duration, hemostasis, and immediate anastomotic strength. Postoperative monitoring tracked vital signs, physiological parameters, healing progression (assessed via burst pressure), histopathological features, and inflammatory cell infiltration.
resultsHFEW application reduced surgical duration and postoperative bleeding. Healing progression was comparable between HFEW and Suture groups. At 1 week postoperatively, vital signs and tissue strength normalized in experimental animals, with necrotic tissue replaced by regenerated tissue; Suture group specimens exhibited elevated inflammatory cell infiltration. By week 2, tissue strength further improved, inflammation subsided, and tissue morphology advanced. At 4 weeks, pathological structures in both HFEW and Suture groups closely resembled normal tissue. Compared with sutures, HFEW has advantages in terms of operating time and blood loss. During the postoperative healing phase, HFEW can effectively reduce the inflammatory response and accelerate healing.
conclusionsPostoperative healing with HFEW-based intestinal repair demonstrates comparability to manual suturing, while exhibiting reduced complication rates - offering residue-free foreign body anastomosis solution for laparoscopic surgery.
