Entero-Enteric Lumen Apposing Metal Stents (LAMS) for Biliary Access in Patients with Altered Anatomy.
Article in Digestive diseases and sciences, 2026. 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
BACKGROUND AND
aimsBiliary access in patients with Roux-en-Y hepaticojejunostomy, pancreaticoduodenectomy and duodenal switch can be challenging. Placement of an EUS guided lumen apposing metal stent (LAMS) between the small bowel and the afferent jejunal limb can create an entero-enteric conduit (EUS-EE), allowing for successful endoscopic access to the biliary tree for intervention. In this study, we aim to describe the safety and efficacy of EUS-EE for biliary access.
methodsThis is a multicenter retrospective cohort study of patients who underwent EUS-EE for the purpose of biliary intervention at three US centers. The primary outcome was technical success. Secondary outcomes included clinical success, defined as ability to perform intended biliary intervention and adverse events. Descriptive statistics were used to analyze the data.
resultsEighteen patients underwent EUS-EE for biliary access. The most common surgical anatomy was a Roux-en-Y hepaticojejunostomy (66.6%). 72.2% of patients had either deep enteroscopy or a hepaticogastrostomy attempted for biliary access prior to proceeding with EUS-EE placement. A 20 mm LAMS was used in 12 patients and 15 mm used in 6 patients. Technical and clinical success was achieved in 100% of patients. Two adverse events were noted; 1 patient had a perforation of the opposite jejunal wall that was treated with through-the-scope clips and one patient had minor bleeding that was managed conservatively.
conclusionThis study demonstrates the feasibility, safety, and efficacy of EUS-EE for management of biliary disorders in patients with surgically altered anatomy. Future large scale multicenter studies are needed to further validate these findings.
