Abstract BackgroundMicrowave ablation (MWA) is a popular therapy for liver malignant tumor in recent years. Few studies have been conducted on its use in the treatment of hepatic alveolar echinococcosis (HAE). The study aims to evaluate the efficacy and safety of MWA in the treatment of HAE.MethodsThis study analyzed the data of 45 patients (mean age,38 ±2 years; 24 males) diagnosed with HAE and underwent MWA treatment between June 2014 to December 2019. The patients after MWA were examined by CT or MRI to determine whether the lesions were relapsed and to evaluate the therapeutic effect of MWA. The safety of MWA was evaluated by monitoring postoperative complications. Clinical data, such as patient demographics, imaging features of the lesions, relevant findings of laboratory tests before and after ablation, and information related to ablation, were collected and analyzed. Paired-sample t tests and paired-sample Wilcoxon signed-rank tests were used to compare relevant laboratory indicators before and after MWA. ResultsMWA was applied to 57 HAE lesions in 45 patients. The median size of lesions was 3.42 cm (IQR2.85-4.41). The rate of complete ablation was 100% (57/57). The median follow-up time was 32 months (IQR 23–48.5). The recurrence rate was 13% (6/45), and the median time of recurrence was 22 months. The rate of minor complications was 11.1% (5/45), and there were no major complications and deaths. Compared to preoperative, ALB, RBC, HBG, and PLT were decreased (p<0.001); ALT, TB, DB, and WBC were increased (p<0.001); and no statistically difference in PT, APTT, and INR (p＞0.05).ConclusionsMWA is a safe and effective way to cure HAE. Meanwhile, it provides a new option and a new way of thinking about the treatment modality for patients with lesions ≤ 5 cm in diameter.

Objective. The aim of our research is to explore the clinical efficacy and safety of CT-guided percutaneous microwave ablation (MWA) for the treatment of lung metastasis from colorectal cancer. Materials and Methods. CT-guided percutaneous MWA was performed in 22 patients (male 14, female 8, mean age: 56.05 ± 12.32 years) with a total of 36 lung metastatic lesions from colorectal cancer between February 2014 and May 2017. Clinical data were retrospectively analyzed with respect to the efficacy, safety, and outcome. Results. Of the 36 lesions, 34 lesions (94.4%) reduced obviously with small cavitations or fibrous stripes formed and had no evidence of recurrence during follow-up. The volume of the other 2 lesions demonstrated local progression after 6 months by follow-up CT. The primary complications included pneumothorax (28%), chest pain (21%), and fever (5%). These symptoms and signs were obviously relieved or disappeared after several-day conservative treatment. The mean follow-up of the patients was 25.54 ± 12.58 months (range 2–41 months). The estimated progression-free survival rate was 94.4%. Conclusion. Our results demonstrate that CT-guided percutaneous MWA appears to be an effective, reliable, and minimally invasive method for the treatment of lung metastasis from colorectal cancer. This trial is registered with ChiCTR-ORC-17012904.

Cystic echinococcosis (CE) or hydatidosis (hydatid cysts) is an infection with a wide spectrum of manifestations, from symptomatic infection to fatal disease. Ultrasound (US) allows screening, diagnosis, differential diagnosis, treatment guidance and follow-up of CE under many circumstances. Hydatid cysts are predominantly observed in the liver. Herewith we present a review to demonstrate established and innovative imaging features of CE of the hepatobiliary tract.

Abstract Objective The present study aimed to evaluate the short-term clinical performance and safety of percutaneous microwave ablation (MWA) techniques for the treatment of bone tumors. Methods This single-institution retrospective study investigated 47 cases of bone tumors treated by MWA from June 2015 to June 2018. The study included 26 patients (55.3%) with benign bone tumors and 21 patients (44.7%) with malignant bone tumors. The tumors were located in the spine or sacrum (15, 31.9%), the upper extremities (6, 12.8%), the lower extremities (17, 36.2%) and the pelvis (9, 19.1%). Outcomes regarding clinical efficacy, including pain relief, quality of life, and intervention-related complications, were evaluated before and after MWA using the visual analog scale (VAS) and the 36-item Short-Form Health Survey (SF-36) scoring system. Results Of the 47 patients included in this study, all of them completed follow-up examinations, with a mean follow-up duration of 4.8 ± 1.6 months (range, 2–9 months). Significantly improved VAS and SF-36 scores were recorded after the initial treatment (P<0.001), suggesting that almost 100% of patients experienced pain relief and an improved quality of life following surgery. No major intervention-related complications (e.g., serious neurovascular injury or infection) occurred during or after the treatment. We recorded only three minor posttreatment complications (6.4%, 3/47), which were related to thermal injury that caused myofasciitis and affected wound healing. Conclusion In our study, the short-term efficacy of MWA was considerably favorable, with a relatively low rate of complications. Our results also showed that MWA was effective for pain relief and improved patients’ quality of life, making it a feasible treatment alternative for bone tumors.

Retrohepatic Inferior Vena Cava

This study evaluates the feasibility of retrohepatic inferior vena cava (RHIVC) resection without reconstruction in patients with end-stage hepatic alveolar echinococcosis (AE). Four hundred and fifty-seven patients diagnosed with hepatic AE and who underwent surgical resections between January 2010 and October 2018 were retrospectively analyzed. Nine patients receiving RHIVC resection without reconstruction were included in this study. Among the patients, 5 were male and 4 female. Mean follow-up time was 64.4 months (18-95). In this series, adequate collateral circulation was formed before operation in all patients, and 7 cases underwent ex vivo liver resection and autotransplantation (ELRA) and 2 cases underwent extended right hemi-hepatectomy. Average standard liver volume, graft volume, surgical time, and anhepatic phase in ELRA group patients was 1144 ± 127 cm3, 740 ± 235 cm3, 16.8 ± 4.1 hours, and 337.4 ± 108.65 minutes respectively. Average hospital stay time for all patients was 45 ± 36.4 days. There were no intraoperative deaths. The 30-day mortality rate was 11.1%, and total mortality rate was 22.2%. Postoperative complications occurred in 4 patients. During follow-up, no relapsed AE lesions were found. RHIVC resection without reconstruction is a feasible way for hepatic AE patients with adequate collateral circulation. Careful protection of collateral venous is the key factor for successful operation.

Background Treatments for anal intraepithelial neoplasia (AIN) are still being established. Methods: An audit of patients referred for treatment of anal disease by CO2 laser at a Perth SHS was performed. Patient demographics including sex, sexual preference, age, and HIV status were documented. Anal cytology, histopathology, and HPV testing before and after treatment were reviewed in this preliminary analysis. Initial diagnosis of anal disease including AIN was made by high-resolution anoscopy (HRA) and by histological examination. Patients were then referred for treatment. Six-monthly HRA review occurred after treatment and the original site of HGAIN was biopsied. Results: Preliminary analysis of 28 patients included 16 patients with AIN 2 and 12 with AIN 3. After laser treatment, 7 patients had no AIN, 3 had AIN 1, 10 had AIN 2 and 4 had AIN 3, indicating successful reduction in AIN status (Pearson χ2 = 15.2, P = 0.002). The incidence of AIN decreased over the 18 months of follow-up. Conclusions: Studies of CO2 laser ablation of the anal canal are ongoing and need further study. Table 1.
