BACKGROUND Achieving the critical view of safety (CVS) before transection of the cystic artery and duct is important to reduce biliary duct injury in laparoscopic cholecystectomy. To gain more insight into complications after laparoscopic cholecystectomy, we investigated whether the criteria for CVS were met during surgery by analyzing videos of operations(More)
INTRODUCTION Local therapies for liver tumors are considered to be safe. However, cryoablation (CA) has been associated with an exaggerated systemic inflammatory response (SIR). Aim of this study was to assess the degree of SIR after radiofrequency ablation (RFA) in comparison with major (MR) or minor (mR) liver resection. MATERIAL AND METHODS Thirty-nine(More)
BACKGROUND AND OBJECTIVES The K-ras gene is one of the most extensively investigated oncogenes in a wide variety of human tumors, but has rarely been studied in distal bile duct carcinoma (DBDC). We sought to investigate the diagnostic and prognostic value of K-ras codon 12 mutations in this type of tumor. METHODS Forty-seven patients who had undergone(More)
We report genomic abnormalities identified in 14 human primary common bile duct carcinomas analyzed by cytogenetics or comparative genomic hybridization, or both. Combining the results of the two methods of analysis, 11 chromosomal arms were observed to be gained in whole or in part, and 9 chromosomal arms were lost in whole or in part in at least four(More)
BACKGROUND The prognosis of patients with colorectal cancer is poor, especially when there is distant metastatic disease. Local ablation of tumor by radiofrequency ablation (RFA) has emerged as a safe and effective new treatment modality, but its long-term efficacy may be hindered by renewed local tumor growth at the site of RFA. The objectives of this(More)
BACKGROUND Large number of patients with colorectal liver metastasis show recurrent disease after curative surgical resection. Identification of these high-risk patients may guide therapeutic strategies. The aim of this study was to evaluate whether the presence of disseminated tumor cells in bone marrow from patients undergoing surgical resection of(More)
AIMS Patients with breast cancer metastasized to the liver have a median survival of 4-33 months and treatment options are usually restricted to palliative systemic therapy. The aim of this observational study was to evaluate the effectiveness and safety of resection of liver metastases from breast cancer and to identify prognostic factors for overall(More)
AIMS To determine the incidence and prognostic value of p53 immunopositivity in resectable distal bile duct carcinoma (DBDC). METHODS Forty-seven paraffin-embedded archival tumour samples of patients with DBDC, who underwent subtotal pancreatoduodenectomy from 1985 to 1996, were immunohistochemically examined for p53 positivity, using the anti-p53(More)
PURPOSE To investigate whether a single pre-operative dose of 120 mg acetylsalicylic acid (ASA) decreased either (1) emboli rate, as detected by transcranial Doppler (TCD), during and early after carotid endarterectomy (CEA) and (2) clinical intra- and post-operative signs suggestive of embolism or increased bleeding tendency. DESIGN Prospective,(More)
One hundred twenty-six effusion samples from 102 patients were examined by cytology and flow cytometry (FCM). Overall, there was an 84% correlation between cytologic and FCM results. Of the 36 malignant cases determined by cytologic examination, FCM revealed an aneuploid peak in 20 (56%). Image analysis (IA) performed on the malignant cytologic cases with a(More)
