REVIEW
Serge Ginzburg, Jeffrey J Tomaszewski, Alexander Kutikov
Partial nephrectomy is the optimal surgical approach in the management of small renal masses (SRMs). Focal ablation therapy has an established role in the modern management of SRMs, especially in elderly patients and those with comorbidities. Percutaneous ablation avoids general anaesthesia and laparoscopic ablation can avoid excessive dissection; hence, these techniques can be suitable for patients who are not ideal surgical candidates. Several ablation modalities exist, of which radiofrequency ablation and cryoablation are most widely applied and for which safety and oncological efficacy approach equivalency to partial nephrectomy...

BACKGROUND: Traditionally, open hepatic resection is the first choice of treatment for symptomatic enlarging hepatic hemangiomas, which requires a large abdominal incision and is associated with substantial recovery time and morbidity. Minimally invasive laparoscopic resection has been used recently in liver surgery for treating selected hepatic hemangiomas. However, laparoscopic liver surgery poses the significant technical challenges and high rate of conversion. Radiofrequency (RF) ablation has been proved feasible in the treatment of hepatic hemangiomas with a size range of 5...

INTRODUCTION: Management of renal-cell carcinoma (RCC) in patients with Von Hippel-Lindau syndrome (VHL) represents a clinical dilemma: the oncologic outcomes must be weighed against preservation of renal function. Radiofrequency ablation (RFA) is currently used in selected cases for treatment of small-size RCC. The aim of this study was to evaluate the safety, complications, and functional and oncologic outcomes of RFA in the treatment of RCC in VHL patients. PATIENTS AND METHODS: RCCs were treated with ultrasound-guided RFA or with laparoscopic RFA...

Solitary mediastinal lymph node metastasis of hepatocellular carcinoma (HCC) is rare. We report a case of metachronically solitary mediastinal metastases of HCC treated by video-assisted thoracic surgery (VATS) twice. A 66-year-old man underwent repeated laparoscopic radiofrequency ablation or trans-arterial catheter chemo-embolization against HCC for more than 10 years. The level of alpha fetoprotein protein was elevated, and radiological modalities including FDG-PET revealed solitary mediastinal tumor metachronically...

Purpose The locoregional interventional oncological treatment approach is an accepted modality for liver neoplasms, especially for hepatocellular carcinoma (HCC) and oligonodular liver metastases. Materials and Methods The main aim of ablation therapies like microwave ablation (MWA) is to eradicate all malignant cells in a minimally invasive technique under imaging guidance while preserving the healthy tissue with a sufficient safety margin (at least 5 mm) surrounding the ablated lesion. Results Ablation therapy can be performed via a percutaneous, laparoscopic or intraoperative approach under ultrasound, MRI or CT guidance for adequate localization and monitoring of the ablation process...

Treatment modalities for small renal masses (SRMs) include open or minimally invasive radical or partial nephrectomy, and laparoscopic or percutaneous ablations. Members of the Endourological Society were surveyed to evaluate how practitioner and clinical practice characteristics may be associated with the management of SRMs over time. The survey assessed characteristics of urologists (recency of residency and fellowship training, clinical practice type and location, and treatment modalities available) and their management of SRMs over the past year and over the course of the year 5 years prior...

BACKGROUND: Inoperable hepatocellular carcinoma (HCC) can be treated with laparoscopic radiofrequency ablation (LRFA), which is generally a more accurate and accessible procedure than percutaneous RFA (PRFA). However, few studies have compared survival outcomes between LRFA and PRFA in patients with HCC. AIMS: This study aimed to compare the efficacy of LRFA and PRFA for HCC treatment. METHODS: Patients who underwent PRFA or LRFA as an initial treatment modality between April 2005 and April 2016 were enrolled in this study...

Patients affected by the presence of leiomyomas may incur a substantial physical, emotional, social and financial toll as well as losses in their quality of life. Although many myomas are not amenable to medical therapy or hysteroscopic resection, many others are amenable to minimally invasive surgical approaches. In patients who prefer to retain their fertility, laparoscopic myomectomy should be considered the intervention of choice. In this review we expand on the surgical techniques of both conventional laparoscopic and robotic-assisted myomectomies...

In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...

PURPOSE: Percutaneous radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) has some limitations such as poor sonic window and injury to adjacent organs. The laparoscopic approach has been suggested as an alternative option. The aim of this study was to show the safety and efficacy of laparoscopic RFA for single, small (≤3 cm), and primary or recurrent HCC that is not suitable for percutaneous RFA or surgical resection. METHODS: We reviewed the cases of 37 patients (32 men and 5 women, mean age 61 ± 8...

Angiosarcoma is a rare type of soft tissue sarcoma that accounts for less than 1% of all sarcomas and only 2% of all primary hepatic tumours. Thorotrast, arsenic, and vinyl chloride monomer are frequently listed as occupational exposure risks. The estimated latency is long (10-40 years) in occupational cases and very long (60 years or more) in non-occupational cases. The symptoms and CT-scan appearance of hepatic angiosarcoma (HAS) are non-specific. We present a case of a 65-year-old Caucasian male with history of cryptogenic cirrhosis, low alpha-foetoprotein levels and a single, 4-cm nodule of potential atypical hepatocellular carcinoma (no washout at MRI and CT-scan) in segment VIII...

Laparoscopic resection of the transplanted kidney has been very rarely reported in the literature. On the one hand, this is due to the extremely low incidence of tumors of renal transplants. On the other hand, these patients are usually managed by open surgery due to difficulties in laparoscopic resection because of the scar tissue in the kidney area. Other options, though rarely performed, are cryosurgery and radiofrequency ablation of the tumor. In this article we report our own experience with a patient who underwent laparoscopic resection of renal transplant for renal cell carcinoma T1aN0M0 19 years after kidney transplantation...
