Experimental evaluation of the fineness of needle forceps: advantages other than minimal access.
Article in Surgery today, 2021. 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
purposeNeedle forceps are used to limit damage to the abdominal wall in endoscopic surgery; however, few experimental studies have evaluated the fineness and performance of needle forceps. We conducted this study to identify the advantages of needle forceps over conventional 5 mm forceps, focusing on fine grasping and needle control.
methodsTwenty physicians executed tasks using 5 mm forceps and 2.1 mm small diameter forceps in a laparoscopic experimental setting. First, we timed the execution and recorded the number of drops in a task of grasping and moving grains of rice and red beans. Next, we measured the execution time, looseness of the knot, and the deviation from the stitching point in a suture and ligation task using suture needles with a diameter of 17 or 26 mm.
resultsThe needle forceps required a significantly shorter execution time to move the rice grains (37.7 s vs. 45.8 s; p = 0.01) and a significantly higher completion rate (90% vs 20%; p < 0.01). The deviation of the stitching point using the 17 mm needle with needle forceps was significantly smaller than with the 5 mm forceps (0.5 mm vs. 1.0 mm; p < 0.01).
conclusionNeedle forceps are better for procedures requiring fine grasping and enable more accurate small diameter needle control than 5 mm forceps.
