Feasibility of endoscopic papillary large balloon dilation to remove difficult stones in patients with nondilated distal bile ducts.
Trial report in World journal of gastrointestinal endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundCurrent guidelines recommend not performing papillary large balloon dilation in patients with nondilated distal bile ducts.
aimTo assess the feasibility of balloon dilation to remove difficult stones in patients with nondilated distal bile ducts.
methodsData from 1289 endoscopic retrograde cholangiopancreatography (ERCP) procedures were obtained from two prospective studies. While 258 cases had difficult stones (> 1 cm, multiple > 8, impacted, or having a thin distal duct), 191 underwent biliary dilation up to 15 mm after endoscopic sphincterotomy. Cholangiographies of these cases were retrospectively reviewed in order to classify the distal bile duct and both the stone size and number. Primary outcomes were clearance rate at first ERCP and complications.
resultsOf the 191 patients (122 women and 69 men; mean age: 60 years) who underwent biliary dilation for difficult stones, 113 (59%) had a nondilated or tapered distal duct. Patients with a dilated distal duct were older than those with nondilated distal ducts (mean 68 and 52 years of age, respectively;
conclusionLarge balloon dilation for difficult stones is feasible in patients with a nondilated or even tapered distal duct.
