This prospective, multicenter randomized crossover trial compared the KARAHOC anchoring catheter (KH) with a conventional angiocatheter (CA) for repeated paracentesis in 87 patients with cirrhosis and refractory ascites. In the intention-to-treat analysis, successful drainage of at least 3 L occurred more often with KH than CA (87.5% vs. 71.6%; OR 2.78, 95% CI 1.22-6.30; p = 0.018). Median procedure time was also shorter with KH (71 vs. 80 min; p = 0.018), and patient and operator satisfaction were higher. Adverse events were comparable, with no major complications.
Key findings
- Intention-to-treat paracentesis success was 87.5% with KH versus 71.6% with CA (OR 2.78, 95% CI 1.22-6.30; p = 0.018).
- Median procedure time was 71 min with KH and 80 min with CA (p = 0.018).
- Patient and operator satisfaction were higher with KH (both p < 0.001).
- Adverse events were comparable, and no major complications occurred.
Why it matters
Repeated large-volume paracentesis is standard care for refractory ascites, and catheter kinking or dislodgement can hinder drainage. In this trial, the anchoring catheter improved procedural success and efficiency while maintaining comparable safety. These results provide comparative evidence for a device option intended to improve catheter stability during paracentesis.
What to keep in mind
The trial enrolled patients at three Korean academic hospitals; the abstract does not report longer-term outcomes beyond the procedures studied.
