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

backgroundMany studies have failed to demonstrate significant differences between single- and two-staged approaches for the management of choledocholithiasis with concomitant gallstones in terms of post-operative morbidity. However, none of these studies paid specific attention to the differences between the methods of accessing the bile duct during laparoscopy. The aim of this study was to report outcomes of transcystic versus transductal laparoscopic common bile duct exploration (LCBDE) from our experience of over four hundred cases.

methodsRetrospective review of 416 consecutive patients who underwent LCBDE at a single-centre between 1998 and 2018 was performed. Data collected included pre-operative demographic information, medical co-morbidity, pre-operative investigations, intra-operative findings (including negative choledochoscopy rates, use of holmium laser lithotripsy and operative time) and post-operative outcomes.

resultsTransductal LCBDE via choledochotomy was achieved in 242 patients (58.2%), whereas 174 patients (41.8%) underwent transcystic LCBDE. Stone clearance rates, conversion to open surgery and mortality were similar between the two groups. Overall morbidity as well as minor and major post-operative complications were significantly higher in the transductal group. The main surgery-related complications were bile leak (5.8% vs 1.1%, p = 0.0181) and pancreatitis (7.4% vs 0.6%, p = 0.0005). Median length of post-operative stay was also significantly greater in the transductal group.

conclusionThis study represents the largest single study to date comparing outcomes from transcystic and transductal LCBDE. Where possibly, the transcystic route should be used for LCBDE and this approach can be augmented with various techniques to increase successful stone clearance and reduce the need for choledochotomy.
