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

backgroundAfter surgery for congenital biliary dilatation (CBD), hilar and hepatic bile duct stenosis and intrapancreatic bile duct remnants can cause many postoperative complications. We investigated the efficacy of laparoscopic surgery with aggressive bile ductoplasty and complete excision of the intrapancreatic bile duct in CBD patients compared to open surgery.

methodsPediatric patients who underwent surgery for CBD at our institution between 2006 and 2020 were divided into two groups: laparoscopic surgery (Lap group) and open surgery (Op group). Surgical outcomes were compared between the two groups.

resultsWe enrolled 160 patients (85 in the Lap group and 75 in the Op group). Hilar bile ductoplasty was performed in 52 (61%) patients from the Lap group and 40 (53%) patients from the Op group. The operative time was significantly longer, the amount of blood loss was significantly lower, and the length of hospital stay was significantly shorter in the Lap group than in the Op group. Postoperative early and late complications occurred at a similarly low rate in both groups. When the surgical outcomes were compared between the group who underwent laparoscopic bile ductoplasty and the group that did not, postoperative early and late complications occurred similarly in both groups.

conclusionsLaparoscopic surgery for CBD with aggressive hilar bile ductoplasty and complete excision of the intrapancreatic bile duct is safe and effective, comparable to open surgery. However, it is necessary to verify whether long-term occurrence of hepatolithiasis similar to open definitive surgery can be obtained in the future.
