Permanent stenting in "unextractable" common bile duct stones in high risk patients. A prospective randomized study comparing two different stents.
Trial report in Langenbeck's archives of surgery, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled 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.
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
backgroundEndoscopic sphincterotomy (ES) and stone extraction is the treatment of choice for bile duct stones. Therefore, if ES and conventional stone extraction fail, further treatment is mandatory. Insertion of a biliary endoprosthesis is an effective option. MATERIALS AND
methodsWe treated 30 high-risk patients (17 women and 13 men, mean age 82 years) affected by difficult common bile duct stones. The patients were randomly assigned preoperatively using closed envelopes (blind randomization) into two groups to receive insertion of polyethylene or hydrophilic hydromer-coated polyurethane stent, respectively. Follow-up was achieved by contacting referring physicians and patient's relatives.
resultsBiliary drainage was established in all patients. Early minor complications occurred in 28%. In all these patients, the stent was a definitive measure. Median follow-up was 38 months. Late complications occurred in 34%. Cholangitis was the most frequent. During follow up, 11 patients died, two as result of a biliary-related cause. No statistically significant difference was observed on different stents patency.
conclusionEndoprosthesis insertion as a permanent therapy is an effective alternative to surgery or dissolution therapy. Therefore, biliary stenting should preferably be restricted to high-risk patients unfit for operative treatment and with a short life expectancy.
