Purpose  

We aimed to determine safety and efficacy of radiofrequency ablation (RFA) in the treatment of lung metastases arising from sarcoma.     

Characteristics of Patients Undergoing Hysterectomy for Failed Endometrial Ablation

Background and Objectives:

Endometrial ablation is a minimally invasive procedure for menorrhagia. High success rates are documented with >90% of patients experiencing satisfaction. However, adequate relief after endometrial ablation is not obtained in a cohort of patients. The purpose of this study is to identify the characteristics of patients for whom endometrial ablation fails due to persistent symptoms, causing them to choose hysterectomy for definitive treatment.

Methods:

We conducted a retrospective chart review of patients who underwent hysterectomy for persistent menorrhagia, pain, or both, who previously had endometrial ablation. We reviewed medical records including pathology reports from hysterectomy. We compared demographics to a group previously studied at our institution that were identified as satisfied 5 years after ablation.

Results:

The number of patients in our study group was 51 (n = 51). Median age of patients was 39 (range 29–50) years. Average body mass index was 31 (range 19–47) kg/m². Average parity was 1.9. Sixty-nine percent underwent tubal ligation. The majority were nonsmokers (75%). Ninety-six percent were Caucasian. Compared with the previously studied satisfied group, the only statistically significant difference was age.Of 51 patients, 11 (22%) noted pelvic pain as their chief concern. Menorrhagia was the chief concern in 22 (43%). Eighteen patients (35%) complained of both. The most common diagnosis was endometriosis, which was identified in 35 patients (68%). Leiomyomata were present in 33 patients (64%). Adenomyosis was identified in 22 patients (43%).

Conclusions:

Patients who present for hysterectomy after endometrial ablation have a high rate of endometriosis, adenomyosis, and leiomyomata, with endometriosis being the most common finding.     

Safety and Efficacy of Microwave Ablation of Hepatic Tumors: A Prospective Review of a 5-Year Experience

Background  

This study was designed to evaluate the safety, efficiency, effectiveness, and overall long-term outcome in patients treated with microwave thermal ablation of hepatic tumors. Microwave ablation technology represents the next generation in ablative techniques for the treatment of hepatic malignancies. Currently there have been no large reports of its use in the United States with appropriate long-term follow-up.     

Management of Small Hepatocellular Carcinoma: A Review of Transplantation,Resection, and Ablation

Purpose and Design  

The management of patients with early hepatocellular carcinoma has become increasingly complex. The most appropriate therapy largely depends on the functional status of the underlying liver. Here we review the modalities of transplantation, resection, and ablation in this patient population.     

Patterns of Recurrence After Ablation of Colorectal Cancer Liver Metastases

Purpose  

To determine the local recurrence rate and factors associated with recurrence after intraoperative ablation of colorectal cancer liver metastases.     

Surgical Resection Versus Laparoscopic Radiofrequency Ablation in Patients With Hepatocellular Carcinoma and Child-Pugh Class A Liver Cirrhosis

Background  

This study compared two homogeneous groups of patients submitted to either surgical resection (HR) or laparoscopic radiofrequency ablation (LRFA) for the treatment of hepatocellular carcinoma (HCC). When compatible with the liver functional reserve, HR remains the treatment of choice for HCC, while LRFA seems to be a promising, less invasive alternative. We thus compared HR or LRFA for short- and long-term outcomes in patients with a single HCC nodule and Child-Pugh class A liver cirrhosis.     

CT-Guided Radiofrequency Ablation of Pediatric Osteoid Osteoma Utilizing a Water-Cooled Tip

Background  

Radiofrequency ablation (RFA) has a success rate of 70% to 90% in the treatment of osteoid osteoma (OO). Failures are due to malpositioning of probes or incomplete ablation, possibly related to conventional probes’ small heating diameter (range, .5–.8 cm). Cooled-tip probes have a larger heating distance, ablating up to 3 cm, affecting a larger volume, and improving success rate in adults. Concerns regarding damage to surrounding structures and unknown effects on bony growth potential have delayed the widespread use of cooled tips in children. Our goal was to examine whether this technique, when added to conventional RFA, improves the clinical results and whether it carries any additional risks to children.     

A Novel Technique of Partial Splenectomy Using Radiofrequency Ablation

Introduction  

Partial splenectomy has frequently been advocated to avoid the risk of overwhelming postsplenectomy sepsis. Concerns over adequate haemostasis during partial splenectomy, however, have limited its widespread use. We have previously reported our experience of using radiofrequency (RF) ablation to minimise blood loss during hepatic and splenic resections.     

Surgical Resection Versus Local Ablation for HCC on Cirrhosis: Results from a Propensity Case-Matched Study

Background  

Surgery for hepatocellular carcinoma (HCC) had great improvements in the last decades with low morbidity and mortality and good long-term results. Percutaneous local ablative therapies (LAT) such as radiofrequency ablation and ethanol injection (PEI) for HCC gained consent for their efficacy and safety. In retrospective studies, patients submitted to resection (LR) or LAT frequently have important selection bias. Propensity case-matched analysis proved to reduce selection bias of retrospective studies and allow comparison between different therapies.
