Cholangiocarcinoma (CCA) is a rare biliary tract epithelial malignancy. We described the clinical features of CCA patients in our institution. A 10-year retrospective study of patients with cholangiocarcinoma in University Malaya Medical Centre was conducted. Clinical data and outcomes in relation to the three anatomical groups of CCA were collected and analysed. Of the 69 patients that were included 55% were male. Mean age was 61 years. Twelve (17%) had intrahepatic, 38 (55%) perihilar and 19 (28%) distal tumour. Mean age (p=0.043), median duration of symptoms (p=0.011), jaundice (p<0.001), total bilirubin level (p=0.003), INR (p=0.005) and mean tumour size (p=0.048) were significantly related to the site of tumour. Only 12 patients had curative resection with seven R0 resections. Cholangiocarcinoma is increasingly diagnosed in our population. Despite that, the diagnosis is still often late. Age, jaundice and tumour size may predict anatomical location of CCA.
A study was conducted at the Department of Pathology, University of Malaya Medical Centre, Kuala Lumpur into the histological type (WHO classification), grade (modified Edmondson and Steiner's grading system), mitotic rate, bile production, hyaline globule and Mallory hyaline formation of 52 cases of hepatocellular carcinoma (HCC) diagnosed during a 13-year period between 1st January 1990 to 31st December 2002. In addition, associated cirrhosis, dysplasia (large liver cell dysplasia: LLCD and small liver cell dysplasia: SLCD) and microvascular permeation were also looked for whenever the situation permitted. The patients' ages ranged from 21-years to 85-years (mean = 58.7 years) with a predilection for males and Chinese. Histologically, majority (73.1%) of the tumours demonstrated a trabecular pattern of growth. The bulk (73%) of the tumours were either of grade II or III differentiation. Mitotic activity ranged between 0-100/10 high power fields (hpf) with a mean of 22.2/10 hpf. Bile was noted in 25%, hyaline globules 17.3% and Mallory bodies in one case. Concomitant cirrhosis was present in 73.5%. 73.5% of the cases had associated LLCD. 5 with LLCD also showed SLCD. Microvascular permeation was shown in 76.2% of cases. On comparison with findings from other studies, no major difference seems to exist between the histological characteristics of our HCC cases and that of other populations.
To investigate the clinical features and survival of patients treated for cholangiocarcinoma in our institution and to analyze the factors affecting their survival.
Arrhythmogenic right ventricular dysplasia is an inherited disease causing fatty replacement of heart tissue. This disease often presents as T-wave inversion in the anterior leads of the electrocardiogram (ECG) with life-threatening ventricular arrhythmias. In older patients, progressive right and left ventricular failure can develop. This is a case report of postoperative death occurring in a 59-yr-old woman with undiagnosed arrhythmogenic right ventricular dysplasia after hepatic cystectomy. The patient had T-wave inversion in the inferior ECG leads and no history of arrhythmias. During general anesthesia, cardiovascular collapse occurred in the absence of arrhythmias that was unresponsive to resuscitation.
