Objective: To evaluate the short-term clinical outcomes of radiofrequency ablation (RFA) using a radiofrequency (RF) needle device for varicose ulcers.
Methods: From September 2020 to September 2021, a total of 80 patients with varicose ulcers were included in this study. Based on the different surgical methods, the patients were divided into RF group and control groups, with 40 cases in each group.
Background Microwave ablation (MWA) is currently under preliminary investigation for the treatment of multifocal papillary thyroid carcinoma (PTC) and has shown promising treatment efficacy. Compared with surgical resection (SR), MWA is minimally invasive and could preserve thyroid function. However, a comparative analysis between MWA and SR is warranted to draw definitive conclusions.

Background: Ultrasonography is the most widely used technique to diagnose echinococcosis; however, challenges in using this technique and the demand on medical resources, especially in low-income or remote areas, can delay diagnosis. We aimed to develop a deep convolutional neural network (DCNN) model based on ultrasonography to identify echinococcosis and its types, especially alveolar echinococcosis.
Methods: This retrospective, large-scale, multicentre study used ultrasound images from patients assessed at 84 hospitals in China, obtained between Jan 1, 2002, and Dec 31, 2021.
Article Synopsis
- The study investigates the safety and efficacy of microwave ablation (MWA) in patients with multifocal papillary thyroid carcinoma (M-PTC) compared to those with unifocal papillary thyroid carcinoma (U-PTC), using data from 504 patients over five years.
- Results showed that while the complete ablation was achieved in all cases, the tumour disappearance rate was significantly lower and slower for M-PTC patients compared to U-PTC, but the overall safety and complication rates were comparable between the two groups.
- In conclusion, MWA is an effective and safe treatment for selected M-PTC patients, with clinical outcomes similar to those with U-PTC
Objectives: To assess the safety and efficacy of ultrasound-guided thermal ablation for low-risk papillary thyroid microcarcinoma (PTMC) via a prospective multicenter study.
Methods: From January 2017 through June 2021, low-risk PTMC patients were screened. The management details of active surveillance (AS), surgery, and thermal ablation were discussed.
Article Synopsis
- Ultrasound-guided thermal ablation, including microwave and radiofrequency ablation, is being studied as a treatment option for papillary thyroid microcarcinoma (PTMC) in a large patient cohort.
- A retrospective analysis of 725 patients revealed significant tumor size reduction after the procedure, with 71% experiencing complete disappearance of tumors within six months.
- Complications were relatively low, with 2.6% of patients affected, but the procedure proved to be an effective and safe alternative to surgery or active surveillance.
Background Microwave ablation (MWA) and radiofrequency ablation (RFA) have recently attracted interest as minimally invasive treatment modalities for papillary thyroid carcinoma (PTC). However, the ablation outcomes of T1N0M0 PTC are not well characterized. Purpose To evaluate the efficacy and safety of thermal ablation (MWA or RFA) of solitary T1N0M0 PTC in patients who were ineligible for (due to presence of comorbid cardiovascular disease, renal failure, other malignancy, etc) or who refused surgery.

The objective of this study was to evaluate the feasibility, efficacy, and safety of thermal ablation for patients with solitary T1bN0M0 papillary thyroid carcinoma (PTC) who are ineligible for or unwilling to undergo surgery.
Materials And Methods: Data pertaining to 172 patients (38 males and 134 females) who received thermal ablation therapy at 12 hospitals between April 2015 and March 2020 were retrospectively analyzed.
