laparoscopic radiofrequency ablation

Guangfu Li, Kevin F Staveley-O'Carroll, Eric T Kimchi
Radiofrequency ablation (RFA) is an important treatment option for patients with early hepatocellular carcinoma (HCC). RFA offers a reliable, reproducible modality to effectively treat hepatic lesions with minimal collateral damage to the surrounding hepatic parenchyma. In addition to traditional open operative techniques, RFA can be performed percutaneously or laparoscopically to minimize the physiologic insult to the patient. Due to the concomitant hepatic damage and dysfunction that often is present in patients with HCC these factors make RFA a frequently utilized therapeutic option...

PURPOSE: Successful adoption of a new surgical procedure varies among practicing surgeons, and skill acquisition depends on the surgeon's innate ability, the complexity of the technique, and training. We report intraoperative and near-term postoperative outcomes from the Acessa procedure conducted by minimally invasive gynecologic surgeons new to Acessa, and report the surgeons' experiences during the training period. PATIENTS AND METHODS: The study was designed as a postmarket, prospective, single-arm, multicenter analysis of operative and early postoperative outcomes after proctored surgical training with the Acessa device and procedure (laparoscopic ultrasound-guided radiofrequency volumetric thermal ablation of symptomatic fibroids) in premenopausal, menstruating women as conducted in community and university hospitals in the USA and Canada...

Port-site metastasis of hepatocellular carcinoma (HCC) is extremely rare, and only one case has been reported in the English-language literature. Contamination with malignant cells along the needle tract during percutaneous biopsy or radiofrequency ablation is a well-recognized cause of HCC recurrence. Here, we describe a case of port-site metastasis after laparoscopic liver resection of HCC. The patient, who had undergone laparoscopic partial resection of the left lateral segment of the liver 18 months earlier, was diagnosed with HCC...

Gastroesophageal reflux disease (GERD) is defined by the presence of troublesome symptoms resulting from the reflux of gastric contents. The prevalence of GERD is increasing globally. An incompetent lower esophageal sphincter underlies the pathogenesis of GERD. Proton pump inhibitors (PPIs) form the core of GERD management. However, a substantial number of patients do not respond well to PPIs. The next option is anti-reflux surgery, which is efficacious, but it has its own limitations, such as gas bloating, inability to belch or vomit, and dysphagia...

BACKGROUND AND OBJECTIVES: Leiomyoma of uterus forms the most common type of benign tumor of uterus and also the most common pelvic tumor in women. The symptomatology continues to be variable. Surgery has for long been the main mode of therapy for the myomas. For women who wish to retain the uterus for future pregnancies or other reasons, myomectomy is preferred. Recent trend has been toward nonsurgical approaches like GnRH hormone analogs/agonists, RU 486, or selective uterine artery embolization, laparoscopic cryoablation, radiofrequency thermal ablation, and MRGUs...

The liver is a vascular-rich solid organ. Safe and effective dissection of the vessels and liver parenchyma, and control of intraoperative bleeding are the main concerns when performing liver resection. Several studies have confirmed that intraoperative blood loss and postoperative transfusion are predictors of postoperative morbidity and mortality in liver surgery. Various methods and instruments have been developed during hepatectomy. Stapling devices are crucial for safe and rapid anastomosis. They are used to divide hepatic veins and portal branches, and to transect liver parenchyma in open liver resection...

BACKGROUND: Liver resection is the treatment option with the best chance for cure in patients with malignant liver tumors. However, there are concerns regarding postoperative recovery in elderly patients, which may lead to a preference of non-resectional therapies over hepatectomy in this patient population. Although laparoscopic liver resection (LLR) is associated with a faster recovery compared to open hepatectomy, there are scant data on how elderly patients tolerate LLR. The aim of this study was to analyze the perioperative outcomes of LLR in elderly patients with hepatic malignancies, with a comparison to laparoscopic RFA (LRFA)...

BACKGROUND: For the treatment of both primary and metastatic liver tumors, laparoscopic parenchyma-sparing surgery is advocated to reduce postoperative liver failure and facilitate reoperation in the case of recurrence. However, atypical and wedge resections are associated with a higher amount of intraoperative bleeding than are anatomical resections, and such bleeding is known to affect short- and long-term outcomes. Beyond the established role of radiofrequency and microwave ablation in the setting of inoperable liver tumors, the application of thermoablative energy along the plane of the liver surface to be transected results in a zone of coagulative necrosis, possibly minimizing bleeding of the cut liver surface during parenchymal transection...
