Non-parasitic hepatic cysts: B-ultrasound guided percutaneous injection treatment clinical observation. The observed results also support this outcome. Compared with surgery, B-ultrasound guided percutaneous injection sclerotherapy for non-parasitic liver cysts is less invasive, causes less pain, and can be repeated. The first treatment for patients with solitary liver cysts can achieve an effect that more patients are willing to accept, making it a worthy application. The superiority of this method for the treatment of multiple liver cysts in patients deserves further clinical study. Liver with multiple cysts over a wide range, cysts filling the entire liver, increasing cyst compression on liver parenchyma, causing atrophy and necrosis of liver cells around the cysts, eventually leading to a decrease in the number of liver cells and liver function, which leads to liver failure; repeated surgical treatment for part of the cyst is unrealistic. Continuously repeated puncture and injection sclerotherapy for large liver cysts may slow down the liver damage caused by the cyst's oppression on liver tissue, improving or slowing down liver failure. So far, there has not been much reported in this area, with differing opinions, but there is a necessity to conduct clinical studies in this regard, in order to obtain convincing clinical data.
