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

backgroundLarge sheet-type surgical materials (e.g., absorbable hemostat, adhesion barrier membranes, and flat surgical mesh) are difficult to introduce into a corporeal cavity using a 5-mm trocar; however, laparoscopic surgeries that use mainly 5-mm trocars are increasing. Furthermore, it is necessary not only to introduce but also to secure the applied surgical material and expand it from the original surgical site. To address these challenges, we developed a novel procedure for introducing such surgical materials into a corporeal cavity using a 5-mm trocar and a self-expanding origami structure, called the "chevron pleats procedure (CPP)".

methodsWe used CPP in 114 cases of laparoscopic surgery for gastrointestinal diseases. The chevron folding pattern is an excellent origami structure and compactly folds a large sheet of material for use with a slim trocar. Surgical materials were folded using a chevron pleats pattern and inserted into a novel, slim, long syringe-type device, which was made from a specially ordered precision polypropylene tube, for introduction into a corporeal cavity. When the surgical material was used, the end of the device was placed above the surgical site and the inner rod was pushed. The surgical material was securely injected and expanded over the surgical site.

resultsSurgical materials were introduced smoothly and securely using a 5-mm trocar to a site of intraoperative bleeding, the incisional surface of the liver, and defects of the abdominal wall or peritoneum. Efficient hemostasis was attained, the introduction and expansion of surgical mesh was made simpler, and the covering of defects of the peritoneum with adhesion barrier membranes, which is typically difficult during laparoscopic surgery, was easily performed.

conclusionsCPP is a basic utility procedure for introducing several sheet-type surgical materials into a corporeal cavity with a 5-mm trocar and might help ensure efficient and safe laparoscopic surgery.
