Randomized clinical study for assessment of incision characteristics and pain associated with LESS versus 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
backgroundLaparoendoscopic single-site surgery (LESS) has emerged as a technique that uses a natural scar, the umbilicus, within which a multiple-entry portal is placed into a 3.0-4.0-cm single incision to perform operations. The objective of this study was to compare incision size, wound complications, and postoperative pain of LESS compared with those of laparoscopic cholecystectomy (LC).
methodsA prospective randomized controlled study was conducted between January and June 2011 at two university hospitals in Rio de Janeiro, Brazil. Fifty-seven patients were randomly assigned to undergo laparoscopic or LESS cholecystectomy. Skin and aponeurosis wound sizes were recorded. A 10-point visual analog scale (VAS) was used to assess pain at postoperative hours 3 and 24. Healing and wound complications were assessed at follow-up.
resultsA total of 57 patients, 53 women and 4 men with a mean age of 48.7 years, were randomly assigned to undergo LESS (n = 28) or LC (n = 29). The mean length of the umbilical skin incision was 4.0 cm (range = 2.1-5.8) in LESS and 2.7 cm (1.5-5.1) in LC (p < .0001). The mean internal aponeurosis diameter was 3.5 cm (2.0-5.5) in LESS and 2.3 cm (1.2-3.5) in LC (p < .0001). The mean operative time was 60.3 min (32-128) for LESS and 51.3 min (25-120) for LC (p = 0.11). Gallbladder perforation at detachment occurred in 15.69 % of the LESS cases and in 5.88 % of the LC cases (p = 0.028). The mean VAS score for pain at hour 3 was 2.0 points (0-7) for the LESS group and 4.0 (0-10) for the LC group (p = 0.07), and at postoperative hour 24 it was 0.3 points (0-6) for LESS and 2.3 (0-10) for LC (p = 0.03). There were no significant differences in wound complications. Incisional hernias were not found in either group.
conclusionsThe LESS single-port (SP) operations demand a bigger incision than LC surgery. However, there were no differences in healing, wound infections, and hernia development. We found a tendency of less postoperative pain associated with LESS/SP than with LC.
