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

BACKGROUND AND

aimsSingle-operator cholangioscopy (SOC) has been suggested to be a cost-effective strategy for the detection of cholangiocarcinoma (CCA). The aim of this study is to compare the performance characteristics of SOC-guided biopsies and transpapillary biopsies with standard sampling techniques for the detection of CCA.

methodsA retrospective cohort study of patients undergoing SOC between 1/2007 and 10/2018 at a single academic center was performed. Demographic, procedural, and outcomes data were recorded and analyzed using STATA 14.0. Sensitivity comparison between diagnostic tests was performed using exact McNemar test exclusively among patients with CCA. Two-sided p value < 0.05 was considered statistically significant.

resultsNinety-two patients were included; 36 (39.1%) with primary sclerosing cholangitis (PSC), 41 (44.6%) with CCA, and median follow-up was 15.1 months. In the overall cohort, brush cytology demonstrated a sensitivity of 44.7% and increased with the addition of FISH (56.8%; p = 0.12), FISH with SOC-guided biopsy (71.4%; p = 0.03), and FISH with transpapillary biopsy (64.5%; p = 0.01). However, in patients with PSC, there was no significant improvement in sensitivity with the addition of SOC-guided biopsy or transpapillary biopsy in addition to FISH when compared to brush cytology. There was no difference in the rates of overall adverse events (14% vs. 23.2%; p = 0.27) or infection (3% vs. 4%; p = 0.83) in patients with and without PSC.

conclusionsSOC-guided and transpapillary biopsies improve sensitivity for the detection of cholangiocarcinoma in combination with other ERCP-based techniques compared to brush cytology alone. However, while safe, these modalities do not significantly improve the sensitivity for the detection of malignancy in PSC patients.
