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

purposePostoperative anastomotic stricture (PAS) is a well-known complication after correcting choledochal cyst (CC). Although the exact cause of PAS is unknown, various risk factors, such as Todani classification type IV-A, hepaticoduodenostomy, and narrow anastomosis have been reported to be associated with PAS. As far as we know, there is no report with a cumulative analysis of such risk factors of PAS. This systematic review and meta-analysis aimed to investigate the risk factors of PAS following surgical correction of CC in children.

methodsA systematic literature search for relevant articles was performed in four databases using the combinations of the following terms "Congenital biliary dilatation", "Congenital choledochal cyst", "Choledochal cyst", "Stenosis", "Stricture", and "Complication" for studies published between 1973 and 2022. The relevant cohorts of PAS were systematically searched for clinical presentation and outcomes.

resultsThe search strategy identified 795 reports. Seventy studies met the defined inclusion criteria, reporting a total of 206 patients with PAS. There is no prospective study in this search. The incidence of PAS was 2.1%. The proportion of Todani classification of the patient with PAS was higher in type IV-A with significant difference (2.0% in type I and 10.1% in type IV-A (p = 0.001)). Fourteen studies reported a comparison between hepaticojejunostomy and hepaticoduodenostomy. There was no significant difference between the two groups (p = 0.36). Four studies reported the diameter of the anastomosis at the primary surgery. The mean diameter was 12.5 mm. Nine studies reported a comparison between laparoscopic surgery and open surgery. Pooled odds ratio of PAS did not show a statistical difference (p = 0.29).

conclusionsThis study suggests that close careful follow-up is important in the patients with type IV-A of CC who underwent excision surgery, considering the possibility of PAS.
