Endoscopic Ultrasound-Guided Hepaticogastrostomy via a Retrosternal Gastric Tube Conduit for Obstructive Cholangitis Caused by Ampullary Carcinoma: A Case Report.
Article in Cureus, 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
Subtotal esophagectomy with retrosternal gastric tube reconstruction alters upper gastrointestinal anatomy and can create two obstacles to endoscopic retrograde cholangiopancreatography (ERCP): displacement and rotation of the pylorus and proximal duodenum, which impede side-viewing duodenoscopy, and ampullary carcinoma, which may obscure the bile duct orifice and prevent selective cannulation. When endoscopic drainage fails, endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) offers an alternative route for internal biliary decompression. Reports of EUS-HGS performed from within a retrosternal gastric tube conduit are limited. A 79-year-old woman with prior subtotal esophagectomy and retrosternal gastric tube reconstruction presented with acute cholangitis and obstructive jaundice caused by ampullary adenocarcinoma. ERCP was abandoned because tumor infiltration obscured the bile duct orifice. EUS-HGS was performed on the same day through the gastric conduit. A 19-gauge puncture and a double-guidewire technique enabled placement of a 7-Fr, 14-cm plastic stent without adverse events. Cholangitis resolved, diet was resumed four days later, and the stent remained patent at 57 days. Histology confirmed adenocarcinoma. EUS-HGS via a retrosternal gastric tube conduit was feasible and achieved internal biliary drainage in a patient with complex post-esophagectomy anatomy and failed ERCP.
