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

backgroundCholecystectomy on index admission for acute cholecystitis is associated with improved patient outcomes. The timing of intervention is mainly driven by service provision. This population-based cohort study aimed to evaluate timing of emergency cholecystectomy in England.

methodsData from all consecutive patients undergoing surgery for acute cholecystitis on index admission in England from 1997 to 2012 were captured from the Hospital Episodes Statistics database. Data were analysed based on whether patients underwent surgery 0-3 days, 4-7 days or ≥ 8 days from admission. Outcome measures were rate of post-operative biliary complications, conversion to open and length of stay.

resultsForty-three thousand eight hundred and seventy patients underwent emergency cholecystectomy. 64.6% of patients underwent surgery between days 0 and 3 of admission, 24.3% between days 4-7 and 11.0% had surgery after day 8. Patients undergoing early surgery had significantly reduced rates of intra-operative laparoscopic conversion to open (0-3 days: 3.6%; 4-7 days: 4.0%; ≥ 8 days 4.7%, p = 0.001), post-operative ERCP (0-3 days: 1.1%; 4-7 days: 1.5%; ≥ 8 days 1.9%, p < 0.001) and bile duct injury (0-3 days: 0.6%; 4-7 days: 1.0%; ≥ 8 days 1.8%, p < 0.001). Early cholecystectomy was also associated with a shorter post-operative length of stay (LOS) [0-3 days group: median post-operative LOS 3 days (IQR: 1-6); 4-7 days group: 3 days (IQR 2-6); ≥ 8 days group: 4 days (IQR 2-9) (p < 0.001)]. High-volume centres undertook a significantly greater proportion of cholecystectomies within 3 days of presentation (high-volume: 67.3%; medium-volume: 64.8%; low-volume: 61.2%). In multivariate analysis greater time to surgery was independently associated with increased risk of post-operative ERCP and bile duct injury.

conclusionsEarly cholecystectomy within 3 days of admission reduces intra-operative conversion, post-operative biliary complications and length of stay. Centres undertaking the greatest numbers of emergency cholecystectomies perform a larger proportion within 3 days of admission.
