Treatment of liver alveococcosis with high-intensity focused ultrasound

Chemical and physical features of biological fluids in treatment of hydatid disease

The aim of this paper is to better understand the dynamics of crystallogenic and starting activity in biological fluids of patients throughout surgery and the late postoperative phase in alveococcosis. Samples of saliva from 22 individuals with alveococcosis were included in the research. Biological fluid samples were taken at the time of admission and before the patient was discharged. Following that, slides were made utilizing the teziocrystalloscopy method, which incorporates the investigation of the crystal forming activity of mixed saliva with its starting characteristics using a 0.9 percent sodium chloride solution as the foundation ingredient. Using our own set of criteria, we evaluated the outcomes of crystalloscopic and tezigraphic experiments. Specrophotometric examination of tezigraphic and crystalloscopic facies was done using a PowerWave XS microplate spectrophotometer at wavelengths of 400, 350, and 300 nm to augment the results from ocular morphometry of dried saliva micro slides. Surgical therapy results in a partial normalization of physical and chemical parameters, as well as the composition of the patient's biological fluids after the patient is discharged from the hospital.

Comparison of Combination Stereotactic Body Radiotherapy Plus High-Intensity Focused Ultrasound Ablation Versus Stereotactic Body Radiotherapy Alone for Massive Hepatocellular Carcinoma

Background

Thermal high-intensity focused ultrasound ablation is a non-invasive treatment of massive hepatocellular carcinomas. In stereotactic body radiotherapy, ablative radiotherapy is administered to tumors in targeted, limited doses to minimize damage to nearby tissues. We evaluated the outcomes and survival of patients receiving stereotactic body radiotherapy (singular therapy) versus those receiving combination thermal high-intensity focused ultrasound ablation plus stereotactic body radiotherapy (combination therapy).

Material/Methods

We compared data of 160 patients with massive hepatocellular carcinomas (12.5–18 cm) who were treated with combination therapy to those treated with singular therapy between January 2009 and February 2016.

Results

Eighty-four patients were treated with single therapy while 76 were treated with combination therapy. Comparison of short-term outcomes and long-term survival between the groups revealed no significant differences in adverse events. In the combination group, the proportions of patients with complete response, partial response, stable disease, and progressive disease were 52.6%, 21.1%, 21.1%, and 5.3%, respectively; in the single therapy group, the corresponding rates were 0%, 23.8%, 50%, and 26.2%, respectively (P<0.0001). The 1-year, 3-year, and 5-year survival rates in the combination group were 33%, 20%, and 13%, respectively, while those in the single therapy group were 21%, 14%, and 1%, respectively. These data indicated no differences in complications between the groups except for a significantly higher level of skin edema in the combination group (P=0.015).

Conclusions

Combination therapy is more effective than single therapy for the treatment of massive hepatocellular carcinomas, although rates of most complications appear to be similar.

High-intensity focused ultrasound ablation: a non-surgical approach to treat advanced and complicated liver alveococcosis

Liver alveococcosis is a life-threatening parasitic disease with progressive growth and wide metastasis to neighboring tissues, lungs, and brain. The radical treatment option is surgery along with a few chemical therapies. However, the frequency of progression and recurrence, as well as postoperative complications and mortality, remains very high. The high-intensity focused ultrasound (HIFU) treatment system, a therapeutic application using ultrasound to deliver heat or agitation into the body, was initially designed to treat cancer. Advanced and complicated forms of liver alveococcosis usually require surgical treatment to provide partial ectomy of necrotized liver tissue along with alveococcal caverns and sanitation of the peritoneal cavity. In this article, we presented a case of successful HIFU ablation with transhepatic puncture and drainage in treatment of complicated and advanced liver alveococcosis to avoid wide surgical treatment.
