BACKGROUND: When a major hepatic resection is necessary, sometimes the future liver remnant is not enough to maintain sufficient liver function and patients are more likely to develop liver failure after surgery. AIM: To test the hypothesis that performing a percutaneous radiofrecuency liver partition plus percutaneous portal vein embolization (PRALPPS) for stage hepatectomy in pigs is feasible. METHODS: Four pigs (Sus scrofa domesticus) both sexes with weights between 25 to 35 kg underwent percutaneous portal vein embolization with coils of the left portal vein...

Liver resection is the standard treatment for any liver lesion. Laparoscopic liver resection is associated with lower intra-operative blood loss and fewer complications than open resection. Access to the posterior part of the right liver lobe is very uncomfortable and difficult for surgeons due the anatomic position, especially when employing laparoscopic surgery. Based on these experiences, a new laparoscopic device was developed that is capable of bending its long axis and allowing the application of radiofrequency energy in areas that were not technically accessible...

Renal cell cancer is nowadays predominantly diagnosed in early stages due to the widespread use of sectional imaging for unrelated symptoms. Small renal masses (<4 cm) feature a largely indolent biology with a very low risk for metastasis or even a benign biology in up to 30% of the cases. Consequently, there is a need for less invasive therapeutic alternatives to nephron-sparing surgery. Meanwhile, there is a broad portfolio of local ablation techniques to treat small renal tumors. These include the extensively studied radiofrequency ablation and cryoablation techniques as well as newer modalities like microwave ablation and irreversible electroporation as more experimental techniques...

A 55-year-old woman underwent laparoscopic anterior resection and D2 lymph node dissection for recto-sigmoid colon cancer in November 2014, which was diagnosed as T3N1M1(H3, PUL2), stage IV , for the purpose of preserving the ileus. FOLFOX therapy with panitumumab(Pmab)was started in January 2015.A t the end of 11 courses, pulmonary metastasis changed to CR, and liver metastasis was down-graded to H2 on the CT.Because of the risk of hepatic dysfunction with advanced fatty liver due to chemotherapy and extrahepatic lesions, we chose radiofrequency ablation(RFA)therapy for liver metastasis...

RATIONALE: Adequate future liver remnant (FLR) volume is often a concern for patients with hepatocellular carcinoma (HCC). Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure can rapidly lead to impressive growth of FLR. We describe the technique of an entirely laparoscopic radiofrequency-assisted liver partition with portal vein ligation for staged hepatectomy (RALPP) in a cirrhotic patient with HCC. PATIENT CONCERNS: A 33 year-old female cirrhotic patient with HCC in the right liver was indicated for RALPP as the predicted future liver remnant (FLR) was 21%...

BACKGROUND: Preservation of hepatic parenchyma is important in liver surgery to prevent postoperative liver failure and according to some reports it could offer a prolonged survival and lower recurrence rates compared to major hepatectomies in patients with colorectal liver metastases. However, laparoscopic parenchyma-preserving liver resections can be technically challenging. The aim of this video is to illustrate the concept of laparoscopic parenchymal-preserving liver resections after conversion chemotherapy with targeted therapy...

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...
