Digital single-operator cholangioscopy: a useful tool for selective guidewire placements across complex biliary strictures.
Article in Surgical endoscopy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 27 papers.
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.
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
backgroundTreatment of biliary strictures is challenging. Digital single-operator cholangioscopes (SOCs) equipped with an improved imaging quality, were recently introduced and may be useful for selective guidewire placement in difficult biliary strictures.
methodsA total of 167 digital SOC procedures performed between 2015 and 2018 were retrospectively analyzed for successful guidewire placements across biliary strictures. Only cases with previous failed conventional guidewire placement approaches were included.
resultsIn total, 30 examinations with a digital SOC-assisted guidewire placement across biliary strictures, performed in 23 patients, were identified. In 52% of all patients, the stricture was benign with post-liver-transplant strictures (75%) as the most frequent finding; in 48% of all patients the stricture was malignant with cholangiocellular carcinoma as the most frequent type (64%). Guidewire placement was successful in 21 of 30 procedures (70%). According to a subgroup analysis, digital SOC-assisted guidewire placements were significantly more successful in patients with benign strictures than those in patients with malignant strictures (88.2% vs. 46.2%; p = 0.02). Furthermore, the technical success rate tended to be increased in cases of initial examinations (78.3%) than in patients with repeated examinations (42.9%; p = 0.15). Adverse events, such as post-interventional pancreatitis or cholangitis as well as severe bleeding occurred in 16.7% of all examinations.
conclusionsDigital SOC-assisted guidewire placements have high technical success rates, especially in benign biliary strictures. This technique can help to avoid more invasive procedures such as percutaneous transhepatic or endoscopic ultrasound-guided biliary drainage.
