Artificial ascites using the guidewire technique during microwave ablation in the liver dome: technique and analysis of fluid repartition.

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
purposeTo describe the guidewire technique to perform hydrodistension and create artificial ascites during liver microwave ablation (MWA) of tumors located in the hepatic dome and evaluate the effectiveness of repartition of peritoneal fluid along segments VII and VIII with this technique. MATERIALS AND
methodsA retrospective review of all 18 consecutive patients who benefited from MWA combined with hydrodistension causing artificial ascites performed with the guidewire technique was conducted. The technique involves inserting a 20G spinal needle in the liver parenchyma and catheterizing the peritoneum with a 0.018 nitinol guidewire while retrieving the needle from the liver. Technical success was defined by the successful insertion of a sheath over the wire in the peritoneal cavity and identification of peritoneal fluid on CT images, with repartition of ascites around segments VII and VIII.
resultsTarget tumors were located in segments VII and VIII and had a mean size of 27.7 mm with a mean distance from the diaphragm of 1.7 mm. Technical success of artificial ascites was 14/18 (78%). In the four cases where artificial ascites failed, patients had undergone previous liver surgery. In the 14 cases for which artificial ascites were successful, complete separation of the diaphragm from the ablation zone was noted in 9/14 cases and partial separation in 5/14 cases.
conclusionHydrodistension with the guidewire technique is effective and safe to accomplish artificial ascites. The extent of repartition of peritoneal fluid is variable, especially in the peritoneal recess in contact with the bare area where diffusion of fluid was variable.
