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

backgroundPostoperative benign bilioenteric anastomotic stricture (BBAS) is a serious complication of biliary surgeries.

aimTo determine the efficacy and safety of percutaneous transhepatic cholangioscopy (PTCS)-assisted procedures, including stricture dilation and recanalization for BBAS and biliary stone therapy for concomitant stones.

methodsPatients with BBAS who received PTCS-assisted procedures were included. Primary outcomes were anastomotic patency (including initial anastomotic patency after stricture dilation and cumulative anastomotic patency after PTCS catheter removal) and treatment success (

resultsForty patients were included; 32 underwent PTCS-assisted stricture dilation/recanalization and 36 underwent biliary stone therapy. The initial patency rates were 58.1% and 41.9% at 1 and 2 years, respectively, and the cumulative patency rates were 74.3%, 59.7, 49.8%, and 34.8% at 1, 3, 5, and 7 years, respectively. The treatment success rate was 90.6% (29/32) for PTCS-assisted stricture procedures. The technical success rates were 100% (31/31), 87.5% (7/8), and 94.5% (34/36) for PTCS-assisted stricture dilation, recanalization, and biliary stone therapy, respectively. The median duration of the indwelling PTCS catheter in the 29 patients with treatment success was 6 (range: 2-109) months. Only one patient experienced acute bleeding, which was manageable.

conclusionPTCS-assisted procedures are efficacious and safe for the management of BBAS and concomitant biliary stones. Placement of an indwelling PTCS catheter across the anastomosis after stricture dilation improves the anastomotic patency.
