Gasless single-port access laparoscopy using a J-shaped retractor in patients undergoing adnexal surgery.
Article in Surgical endoscopy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveThe aim of this study was to compare gasless single-port access (SPA) laparoscopy using a J-shaped retractor and conventional SPA laparoscopy in patients undergoing adnexal surgery. Study design The medical records of 80 patients who underwent laparoscopic adnexal surgery between May 2017 and April 2019 were reviewed. Of the 80 patients, 40 patients underwent gasless SPA laparoscopy using a J-shaped retractor and 40 underwent conventional SPA laparoscopy. All surgeries were performed by one laparoscopic surgeon. Surgical outcomes were compared between the two groups.
resultsThere are no significant differences in age, body mass index, parity, previous abdominal surgery, tumor marker, and tumor diameter between the gasless and conventional groups. The median retraction setup time from skin incision was 7 min (range 5-12 min) in gasless SPA laparoscopic adnexal surgery. The median total operation times were 55.5 min (range 30-155 min) in the gasless group and 55 min (range 30-165 min) in the conventional group without a significant difference. Additionally, there were no differences in operation type, conversion rate of laparotomy, use of an additional trocar, and pathological outcomes between the two groups. No major complications, such as urologic, bowel, and vessel injuries, were found in both groups.
conclusionsGasless SPA laparoscopy using a J-shaped retractor appears to offer a better alternative to conventional SPA laparoscopy that avoids the potential negative effects of carbon dioxide gas in selected cases.
