Noninvasive diagnosis of periportal fibrosis in schistosomiasis mansoni: A comprehensive review.

World J Hepatol 2022 Apr;14(4):696-707

Postgraduate Program in Tropical Medicine, Center of Health Sciences, Universidade Federal de Pernambuco, Recife 50670-901, Pernambuco, Brazil.

Schistosomiasis mansoni is a neglected disease and key public health problem, mainly due to its high prevalence, the scarcity of public policies, and the severity of some clinical forms. Periportal fibrosis (PPF) is the commonest complication of chronic schistosomiasis mansoni and its diagnosis requires different techniques. Even though wedge biopsy of the liver is considered the gold standard, it is not justified in non-surgical patients, and percutaneous liver biopsy may be informative but does not have sufficient sensitivity.

Contemporary evidence on colorectal liver metastases ablation: toward a paradigm shift in locoregional treatment.

Int J Hyperthermia 2022 ;39(1):649-663

Department of Interventional Radiology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Image-guided percutaneous ablation techniques represent an attractive local therapy for the treatment of colorectal liver metastases (CLM) given its low risk of severe complications, which allows for early initiation of adjuvant therapies and spare functional liver parenchyma, allowing repeated treatments at the time of recurrence. However, ablation does not consistently achieve similar oncological outcomes to surgery, with the latter being currently considered the first-line local treatment modality in international guidelines. Recent application of computer-assisted ablation planning, guidance, and intra-procedural response assessment has improved percutaneous ablation outcomes. Read More
