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 only potentially curative option for patients with perihilar cholangiocarcinoma (PHC) is resection, typically an extrahepatic bile duct resection in combination with (extended) liver resection. Complications such as bile leakage and liver failure have been suggested to be more common after right-sided resections compared to left-sided resections, whilst superior oncological outcomes have been reported after right-sided resections. However, data on outcomes after right-sided or left-sided liver resections in PHC are scarce. Therefore, we aimed to investigate short- and long-term outcomes after left and right hemihepatectomy in patients with PHC.

methodsIn this retrospective study, patients undergoing major liver resection for suspected PHC in a tertiary center between 2000-2018 were included. Patients who had undergone left-sided resections were compared to patients with right-sided resections in terms of complications (90-day mortality, overall and severe morbidity and specific complications). For long-term outcomes, only patients with pathologically proven PHC were included in the survival analysis.

resultsA total of 178 patients undergoing hemihepatectomy for suspected PHC were analysed, including 76 left-sided and 102 right-sided resections. Overall 90-day mortality was 14% (24 out of 178), with no significant difference after left-sided resection (11%; 8 out of 76) versus right-sided resection (16%; 16 out of 102) (P=0.319). Severe morbidity (Clavein Dindo ≥3) was also comparable in both groups: 54% versus 61% (P=0.361). No differences in specific complications including bile leakage were observed, although liver failure appeared to occur more frequently after right hemihepatectomy (22% versus 11%, P=0.052). Five-year overall survival for pathologically proven PHC, excluding in-hospital mortality, did not differ; 43.7% after left-sided resection

conclusionsBoth short- and long-term outcomes between patients undergoing left and right hemihepatectomy for PHC were comparable. Post-hepatectomy liver failure was more common after right-sided resection.
