Biliary stent migration after cholecystectomy following a single-preoperative ERCP: insights into real-world bile duct management.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPreoperative endoscopic retrograde cholangiopancreatography (ERCP) with biliary stent placement is commonly employed in patients with choledocholithiasis as part of a staged perioperative management strategy. In clinical practice, biliary stent migration is often observed at the time of planned postoperative ERCP. Characterizing the occurrence of biliary stent migration, its associated clinical factors, and its implications for postoperative management is therefore relevant to optimizing patient care.
methodsWe conducted a single-center retrospective cohort study including adult patients who underwent a single preoperative ERCP with biliary plastic stent placement, followed by cholecystectomy and a planned postoperative ERCP for stent removal between 2012 and 2023. The primary outcome was biliary stent migration, defined as absence of the stent at postoperative ERCP, confirmed endoscopically and fluoroscopically. Demographic, clinical, and procedural variables were analyzed to explore factors associated with stent migration.
resultsA total of 208 patients were included. Biliary stent migration was observed in 51 patients (24.5%). At postoperative ERCP, choledocholithiasis was identified in 67.8% of cases. In univariate analysis, pancreatic stent placement during the index ERCP was associated with lower odds of biliary stent migration; however, this association did not remain statistically significant after multivariable adjustment. No other demographic or procedural factors were independently associated with migration.
conclusionsIndividualized approach may be applied for selective patients referred to the biliary stent removal after cholecystectomy. Abdominal imaging before postoperative ERCP in asymptomatic patients with normal liver function tests may help in the decision-making process and potentially prevent unnecessary invasive procedures and reduce its complications.
