BACKGROUND There are scant data in the literature regarding the role of robotic liver surgery. The aim of the present study was to develop techniques for robotic liver tumour resection and to draw a comparison with laparoscopic resection. METHODS Over a 1-year period, nine patients underwent robotic resection of peripherally located malignant lesions(More)
BACKGROUND The best measure of the technical success of radiofrequency ablation (RFA) is local recurrence (LR). The aim of this prospective study is to identify factors that predict LR. METHODS Three hundred thirty-five patients with 1032 unresectable liver tumors underwent laparoscopic RFA between November 1999 and August 2005. All lesions were assessed(More)
HYPOTHESIS The technique of thyroidectomy has undergone little change in several decades. The harmonic scalpel, using ultrasonic frictional heating to ligate vessels, is widely used in laparoscopic surgery, but there is little experience in open thyroidectomy. We hypothesized that the use of the harmonic scalpel could lead to a significant reduction in(More)
OBJECTIVE To assess factors affecting long-term survival of patients undergoing radiofrequency ablation (RFA) of colorectal hepatic metastases, with attention to evolving chemotherapy regimens. METHODS Prospective evaluation of 235 patients with colorectal metastases who were not candidates for resection and/or failed chemotherapy underwent laparoscopic(More)
OBJECTIVE The aim of this study was to determine the success of limited neck exploration (LE) for primary hyperparathyroidism (1 degrees HPT). METHODS Between 1999 and 2007, 1407 patients with hyperparathyroidism underwent bilateral neck exploration (BE). Of these, 1158 patients with first-time sporadic 1 degrees HPT were analyzed prospectively. Based on(More)
BACKGROUND For the past 14 years, we have been performing laparoscopic adrenalectomy via the lateral transabdominal as well as the posterior retroperitoneal approach. The aim of this study is to describe patient selection criteria for each approach with comparison of perioperative outcomes. METHODS In patients with smaller tumors, low body mass index(More)
OBJECTIVE Clarify the incidence of thyroid cancer in patients with Familial adenomatous polyposis (FAP) in a prospective study of thyroid neck US screening. BACKGROUND FAP is a hereditary disease predisposing to cancer in multiple organs, including the thyroid. However, routine thyroid screening for FAP patients is not generally practiced in the United(More)
BACKGROUND Since our first report 13 years ago, laparoscopic radiofrequency ablation has been incorporated into the treatment algorithm of patients with neuroendocrine liver metastases. The aim of this study is to report long-term oncologic results. METHODS Eighty-nine patients with neuroendocrine hepatic metastases underwent 119 laparoscopic(More)
BACKGROUND Although radiofrequency-assisted (RF) precoagulation has been described for open resections, there is little data evaluating precoagulation options in laparoscopic liver resection. The purpose of this study is to provide an algorithm for the use of monopolar and bipolar RF devices in laparoscopic liver resection. METHODS Patients undergoing(More)
BACKGROUND While normocalcemic hyperparathyroidism is well recognized in primary hyperparathyroidism (PHP), less is known about patients with high calcium but normal intact parathyroid hormone (iPTH). We aimed to describe this entity and designated it normohormonal primary hyperparathyroidism (NHPHP). METHODS From a prospectively maintained database of(More)
