Beyond the "B": a new concept of the surgical staple enabling miniature staplers.
Article in Surgical endoscopy, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundSurgical staplers currently all rely on the same staple form-the "B" which necessitates a high delivery profile (12 mm). A novel "D" shape staple allows for an extremely low profile of the applicator. The acute and long-term efficacy of a D-shaped staple (Cardica, Redwood City, CA, USA) was compared to conventional B-form staples (Covidien, Norwalk, CN, USA) in an animal model for intestinal transections and anastomoses.
methodsJejunojejunal anastomoses (JJ) were performed via mini-laparotomy in a swine model. White & blue D- and B-shaped staples were studied in three groups (planned survival 14-84 days). Intraoperative assessment included completeness of staple line, hemostasis, and need for intervention. Postoperatively, animals were evaluated for complications. At the time of sacrifice, gross pathological and histological assessments were performed.
resultsTwenty-three animals had 40 anastomoses (23 "D" and 17 "B" staple anastomoses) with no intraoperative mortalities. One "D" staple application required a manual extension of the cut. Acute hemostasis was 100%. Group 1 (n = 5) compared white staples in JJs (D staple n = 5; B staple n = 5; 14-day survival = 100%). Group 2 (n = 12) compared white staples in JJs (D staple n = 12; B staple n = 6; 34-day survival = 92 %). One animal died on day 4 for a non-staple related cause. Group 3 (n = 6) compared blue staples in JJs (D staple n = 6; B staple n = 6; 84 day survival = 84%). One animal died on day 18 due to an obstruction at the B staple JJ caused by stricture. There were no other bleeding, leaks or strictures in any of the groups. Gross pathology and histology were unremarkable in all JJs.
conclusionsThis study showed no difference in intraoperative performance and the chronic healing response in JJs between D- and B-shaped staples. Based on these findings, the D-shaped staple elicits a normal healing response in jejunostomies and offers the possibility of clinical use of this advance in staple design.
