Magnetically anchored camera and percutaneous instruments maintain triangulation and improve cosmesis compared with single-site and conventional laparoscopic cholecystectomy.

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 evaluated operative outcomes and ergonomics for a magnetic camera (MAGS) used in conjunction with percutaneous instruments [percutaneous surgical set (PSS)] compared with single-site laparoscopic (SSL) and conventional laparoscopic (LAP) cholecystectomy techniques.
methodsFour surgical trainees each performed three porcine cholecystectomies using three randomized techniques including MAGS/PSS, SSL, and LAP. The operative outcomes, procedure-specific ratings (1-5 scale; 1 = superior), workload (1-10 scale; 1 = superior), and global impressions (1-10 scale; 10 = superior) were recorded. Comparisons used analysis of variance (ANOVA) on ranks (Kruskal-Wallis), and p values lower than 0.05 were considered significant.
resultsThe operative outcomes were similar except for significantly higher blood loss with SSL (16.3 ± 10.3) versus LAP (2.8 ± 1.5; p < 0.05) but not with MAGS/PSS (4.8 ± 3.8). Several inadvertent tissue-damaging events occurred with SSL but not with MAGS/PSS or LAP. The incision was significantly shorter with MAGS/PSS (29.3 ± 2.8 mm) and SSL (29.3 ± 2.5 mm) than with LAP (48.0 ± 3.6 mm; p < 0.05). Compared with SSL (3.6 ± 0.5), the procedure-specific ratings significantly favored MAGS/PSS (2.8 ± 0.4) and LAP (1.7 ± 0.2; p < 0.05). Ergonomics and technical challenges both were rated significantly inferior with SSL (4.3 ± 1.0 and 3.8 ± 0.5, respectively) versus LAP (1.5 ± 0.6 and 2.0 ± 0.8, respectively; p < 0.05) but not with MAGS/PSS (2.5 ± 1.0 and 3.0 ± 0.8, respectively). Both MAGS/PSS (4.5 ± 0.5) and SSL (4.8 ± 1.0) were associated with a significantly greater workload than LAP (2.5 ± 0.6; p < 0.05). Global impression ratings were significantly higher for LAP (8.7 ± 1.3) versus SSL (5.8 ± 2.0; p < 0.05) but not for MAGS/PSS (7.1 ± 1.8). Cosmesis was significantly better with MAGS/PSS (9.5 ± 0.6) versus LAP (6.5 ± 2.4; p < 0.05) but not with SSL (8.8 ± 1.3).
conclusionThe MAGS/PSS technique allows better triangulation and fewer technical difficulties than SSL and better cosmesis than LAP. Further development of these devices is warranted.
