Objective: The objective of this study was to compare laparoscopic ultrasound-guided radiofrequency ablation of fibroids (Lap-RFA) and laparoscopic myomectomy in terms of 1) health care utilization and 2) serious complication rates. The secondary objectives were comparison of subject responses to validated symptom and quality-of-life questionnaires. We hypothesized that Lap-RFA health care utilization and clinical outcomes would not be worse than those of laparoscopic myomectomy in the aggregate...

Background: Laparoscopic liver resection has been gaining momentum, and it has become an accepted practice after the two international consensus conferences where experts worked up guidelines to standardize this approach and improve its safety. However, most laparoscopic hepatectomies were performed in patients with liver metastases. The concurrent presence of liver cirrhosis with hepatocellular carcinoma (HCC) poses a great challenge to clinicians trying to establish a routine use of laparoscopic liver resection for HCC...

OBJECTIVE: To evaluate the microscopic characteristics and quantify the volume of a radiofrequency ablation (RFA) lesion. METHODS: Ten male pigs were submitted to laparoscopic RFA. An RFA needle was introduced in the lower pole of the left kidney to create a lesion expected to be a sphere of 2.0 cm diameter. The animals were followed up for 21 days. Kidneys were weighed and the volume was assessed using Scherle's method. Cavalieri's principle was used to assess the RFA volume, and sphericity was calculated to assess RFA lesion...

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...

We report a case of repeated surgical resections for the tumor seeding of hepatocellular carcinoma(HCC)after radiofrequency ablation(RFA). A 79-year-old man, who had an intrahepatic recurrence of HCC(segment 2)5 months after RFA, was referred to our hospital for surgery, and underwent a laparoscopic lateral segmentectomy. Histological examination showed a poorly differentiated HCC(pStage II). Eight months after RFA, subcutaneous nodules along the RFA needle tract were pointed out by abdominal CT, and a tumorectomy was performed...

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...

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...
