The application of video-assisted thoracic surgery (VATS) for major lung resection is controversial. We review our combined experience from three centers in Asia. From June 1993 through June 1997, 214 patients underwent VATS major resections (2 segmentectomies, 203 lobectomies, 6 bilobectomies, 3 pneumonectomies), mostly for primary malignancy. Stringent(More)
The few reports in the literature on thoracoscopic anatomic lung resections were almost exclusively for early primary lung cancers. We report our combined experience on video-assisted thoracoscopic (VAT) lobectomy for benign diseases from two major hospitals in Hong Kong over a 20-month period. From August 1993 to March 1995, 66 VAT lobectomies were(More)
BACKGROUND Lymphoepithelioma-like carcinoma (LELC), best known to occur in the nasopharynx, can arise in a variety of sites, such as the salivary gland, thymus, lung, stomach, and skin. Primary LELC of the lung is very rare, with only limited information in the literature. METHODS The clinicopathologic features of 11 patients with pulmonary LELC collected(More)
We report our combined experience on video-assisted thoracoscopic (VAT) anatomic lung resections from two major hospitals in Hong Kong over a 17-month period. From August 1993 to December 1994, 82 cases of major lung resections were attempted using the VATS approach, of which 60 were successfully completed (55 lobectomies, 2 bilobectomies, 2(More)
OBJECTIVE To review the results of endovascular treatment of acute thoracic aortic diseases in a group of Chinese patients. DESIGN Retrospective study. SETTING A tertiary referral hospital with a cardiothoracic surgery service. PATIENTS All 15 patients presenting with acute thoracic aortic diseases between September 2001 and October 2005 inclusive, of(More)
Accumulating evidence suggests that the p53 gene is a good target for molecular epidemiological studies to search for risk factors in carcinogenic events. The lung cancer incidence for females in Hong Kong is unusually high, ranking among the highest in the world despite a low percentage with a history of smoking. To gain insights into possible etiological(More)
We report three cases of benign metastasising leiomyoma, which is a rare cause of multiple lung nodules, in three Hong Kong Chinese females. One patient presented with pleuritic chest pain, another was asymptomatic, while the last presented with haemoptysis. All three patients had previously undergone surgical resection of uterine leiomyomas. Multiple lung(More)
OBJECTIVES To evaluate if antihypertensive regimens that conform to present FDA guidelines by maintaining > or = 50% of their peak effect at the end of the dosing interval protect patients during sporadic lapses in adherence. METHODS 169 patients on monotherapy for high blood pressure underwent electronic adherence monitoring for 3 months. Blood pressures(More)
OBJECTIVE To report the surgical experience in the management of patients with synchronous primary lung cancer and solitary brain metastasis. DESIGN Retrospective cohort study. SETTING Regional hospital, Hong Kong. PATIENTS Seventeen patients with synchronous primary lung cancer and solitary brain metastasis were treated by pulmonary resection and(More)
Objective: To characterize the metabolic " fingerprint" of fecal extracts for diagnosis of early-stage colorectal cancer(CRC)using proton nuclear magnetic resonance spectroscopy(1H-NMR)-based metabolomics coupled with pattern recognition. Methods: From January 2014 to December 2014, we collected fecal samples at the Second Affiliated Hospital of Shantou(More)
