Refractory Post-TIPS Hepatic Encephalopathy Complicated by Small Bowel Obstruction: A Therapeutic Dilemma.
Article in Case reports in gastrointestinal medicine, 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
Introduction: Refractory hyperammonemic encephalopathy in cirrhosis presents a therapeutic challenge, particularly in post-TIPS patients or with contraindications to standard therapies. We report a fatal case complicated by small bowel obstruction (SBO), highlighting the limitations of current management strategies. Case Presentation: A 69-year-old male with decompensated NASH cirrhosis and recent TIPS revision for shunt stenosis developed SBO. He presented with severe encephalopathy (GCS 5), seizures, and MRI-confirmed cerebral edema. Due to SBO, lactulose and rifaximin were not effective. Despite aggressive dialysis with continuous venovenous hemodialysis (CVVHD) reducing ammonia from 447 to 160 μmol/L, he progressed to irreversible cerebral edema and met brain death criteria. Discussion: Post-TIPS hyperammonemia carries high mortality, especially when compounded by SBO. CVVHD effectively lowers ammonia but may fail to prevent neurologic injury if initiated late. Conclusion: This case underscores the need for proactive RRT and novel ammonia-lowering strategies in high-risk patients, especially when gut decontamination is not feasible.
