REVIEW
Julian A Gingold, Ndeye-Aicha Gueye, Tommaso Falcone
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...

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...

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...

First reported two decades ago, isolated incisional recurrence of hepatocellular carcinoma is an extremely rare clinical entity. We present two cases of recurrence: one recurring over 10 years after initial resection, and the second presenting with a port site recurrence 3.5 years following laparoscopic radiofrequency ablation. Clinical case presentation, including radiographical, pathological, laboratory and intraoperative images are reported, together with a review of the current literature surrounding this uncommon hepatocellular carcinoma presentation...

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...

Computed tomography-guided radiofrequency ablation (CT-RFA) and laparoscopic RFA (L-RFA) have been used to treat intrahepatic recurrent small hepatocellular carcinoma (HCC) against the diaphragmatic dome. However, the therapeutic safety, efficacy, and hospital fee have never been compared between the two techniques due to scarcity of cases. In this retrospective study, 116 patients were divided into two groups with a total of 151 local recurrent HCC lesions abutting the diaphragm. We compared overall survival (OS), local tumor progression (LTP), postoperative complications, and hospital stay and fee between the two groups...

BACKGROUND AND AIM: Multipolar radiofrequency ablation (RFA) is feasible for the treatment of hepatocellular carcinoma (HCC) for which a large ablative area is planned, and it imposes a light physical burden on patients. Multipolar RFA via the percutaneous approach is performed in the majority of cases, but the efficacy of multipolar RFA with a laparoscopic approach has rarely been studied. This study aimed to evaluate the efficacy and safety of multipolar laparoscopic RFA (LRA) for localized HCC over the short term...

The management of disappearing colorectal liver metastases in the postadjuvant chemotherapy setting is challenging. We describe a novel technique that facilitates laparoscopic resection of disappearing metastatic liver lesions with great precision. Details of this new technique are described in 2 patients with colorectal cancer synchronously metastatic to the liver. Both patients had small indistinct intraparenchymal liver lesions after adjuvant chemotherapy. A video displays the steps of the procedure. Both patients presented with colorectal cancer with synchronous liver metastasis...

Needle tract implantation after percutaneous ethanol injection therapy(PEIT)for hepatocellular carcinoma(HCC)is rare. Surgical treatment of such HCC implants is still controversial. We herein report the case of a patient who underwent laparoscopic resection for peritoneal dissemination after PEIT. An 81-year-old man underwent PEIT for primary HCC at another hospital. Thereafter, percutaneous radiofrequency ablation(RFA)was performed twice for intrahepatic recurrence. After the second RFA, a mass lesion was detected at the subhepatic space on computed tomography(CT)...
