1 · What the graph read from it

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.

2 · The registry

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

backgroundThe global prevalence of obesity has risen significantly, thereby resulting in a consequential increase in the use of bariatric surgical procedures. Optical trocars are extensively utilized for identifying laparoscopic access in patients with morbid obesity. However, their efficacy and safety are dependent on the surgeon's capability to accurately identify anatomical structures during insertion. The current study investigated the influence of anatomical structure recognition and insertion time on successful optical trocar insertion, which can offer insights that are applicable to various surgical specialties.

methodsThis retrospective study was conducted on 143 patients who underwent laparoscopic sleeve gastrectomy. Data on demographic characteristics, comorbidities, anatomical structure recognition, and trocar insertion time were collected. To evaluate the associations between these factors, a statistical analysis using the univariate and multivariate models was performed.

resultsThe recognition of anatomical structures such as the rectus abdominis and peritoneum during the procedure was significantly related to shorter insertion times (p < 0.01). Multivariate analysis revealed that an accurate identification of these structures independently contributed to an efficient trocar placement. The risk of complications increased in cases where the peritoneum could not be clearly identified. However, there were no cases of major vascular or organ injuries, and all complications were managed with conservative treatment.

conclusionsSuccessful trocar insertion in patients with morbid obesity is dependent on the precise recognition of anatomical structures, particularly the rectus abdominis and peritoneum. This approach enhances both procedural safety and efficiency, and the findings may have broader applicability to laparoscopic techniques.
