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

backgroundCommon bile duct (CBD) stones are reported in ~ 15% of patients who undergo laparoscopic cholecystectomy for symptomatic gallstones. Prior to lithotripsy techniques, transcystic laparoscopic common bile duct exploration (LCBDE) was limited to smaller CBD stones. The addition of lithotripsy to LCBDE increases cost, operative time and staffing requirements. Predicting which patients might require lithotripsy would be useful in operative planning. The primary aim was to investigate clinical variables for predicting lithotripsy assistance during transcystic bile duct exploration by laparoendoscopy (PRE-LABEL). Secondary aims were to develop and validate a predictive scoring tool.

methodsA retrospective review of a prospectively collected database of consecutive patients who underwent transcystic LCBDE at a single centre in the UK was performed to investigate clinical variables for PRE-LABEL and develop a scoring tool (ABCdE score: age, bilirubin, CBD diameter, ERCP). Binary logistic regression was used to investigate which independent variables (predictors) were associated with lithotripsy assistance during transcystic LCBDE. The ABCdE score was applied to both UK and Spain patient cohorts to determine its sensitivity, specificity and accuracy.

resultsFrom 8 pre-operative clinical variables analysed, age ≤ 40 years, bilirubin > two-times upper limit of normal, CBD diameter ≥ 10 mm and ERCP failure of stone extraction were independent predictors of requiring lithotripsy during transcystic LCBDE and formed the ABCdE score. The hazard ratios were 2.87, 3.79, 2.78 and 10.06, respectively. An ABCdE score ≥ 2 resulted in 71% sensitivity, 81% specificity and 79% accuracy in predicting lithotripsy during LCBDE (UK cohort). Validation using a contemporary cohort from Spain yielded similar sensitivity, specificity and accuracy.

conclusionsThis study represents the only study to date reporting independent predictors of requiring lithotripsy assistance during transcystic LCBDE. ABCdE score ≥ 2 can highlight patients that may require lithotripsy in order to avoid failure of transcystic LCBDE and therefore avoid choledochotomy or post-operative ERCP.
