ABSTRACT

AIMS: Cholangiocarcinoma is a rare cancer arising from the biliary tree. Case series indicate that 25-40% of all borderline resectable primary tumours are potentially resectable. The Memorial Sloane Kettering System (MSKCC) stratifies patients for resectability by longitudinal and radial extension of the hilar tumour. The Bismuth-Corlette system describes the longitudinal extension of the tumour within the biliary duct system. We sought to validate and, if possible, augment these two scores within an independent validation cohort. METHODS: Patients diagnosed with hilar cholangiocarcinoma between January 2009 and December 2016 were analysed from a prospectively held database. Patients with distal cholangiocarcinoma, peripheral cholangiocarcinoma and gallbladder cancer were excluded. Comparison of surgical findings to pre-operative radiological imaging was undertaken at the time of surgery. RESULTS: The validation cohort was formed of 198 patients, of which, 55 (27.8%) patients underwent resection. Logistic regression analyses identified that BC score, MSKCC score, age at diagnosis and left artery involvement were all significant independent predictor's univariately. BC score explained 28% of the variability in resectability compared to 26% explained by MSKCC. In combination, the model consisting of BC score, age at diagnosis and left artery involvement explained 39% of variability in resectability compared to the 34% explained same model including MSKCC score instead of BC score. CONCLUSION: In this cohort an augmented BC score, incorporating left hepatic artery involvement, is more discriminative in predicting resectability than the current MSKCC system.

ABSTRACT

INTRODUCTION: Streptococcus bovis can lead to bacteraemia, septicaemia, and ultimately endocarditis. The objective of this study was to evaluate the long-term implications of S. bovis endocarditis on cardiac morbidity and mortality. METHODS: A retrospective cohort study was performed between January 2000 and March 2009 to assess all patients diagnosed with S. bovis bacteraemia from the Belfast Health and Social Care Trust. The primary end-point for cardiac investigations was the presence of endocarditis. Secondary end-points included referral for cardiac surgery and overall mortality. RESULTS: Sixty-one positive S. bovis blood cultures from 43 patients were included. Following echocardiography, seven patients were diagnosed with infective endocarditis (16.3 % of total patients); four patients (9.3 %) had native valve involvement while three (7.0 %) had prosthetic valve infection. Five of these seven patients had more than one positive S. bovis culture (71.4 %). Three had significant valve dysfunction that warranted surgical repair/replacement, one of whom was unfit for surgery. There was a 100 % recurrence rate amongst the valve replacement patients (n = 2) and six patients with endocarditis had colorectal pathology. Patients with endocarditis had similar long-term survival as those with non-endocarditic bacteraemia (57.1 % alive vs. 50 % of non-endocarditis patients, p = 0.73). CONCLUSION: Streptococcus bovis endocarditis patients tended to have pre-existing valvular heart disease and those with prosthetic heart valves had higher surgical intervention and relapse rates. These patients experienced a higher rate of co-existing colorectal pathology but currently have reasonable long-term outcomes. This may suggest that they represent a patient population that merits consideration for an early surgical strategy to maximise long-term results, however, further evaluation is warranted.

ABSTRACT

We report a case of a diagnosis of Williams syndrome in a 57-year-old male referred for cardiac surgery with a presumptive diagnosis of aortic valvular stenosis and ascending aortic aneurysm, supravalvular stenosis being first suspected during surgery. Williams syndrome was subsequently confirmed via genetics testing. In patients presenting with an ascending aortic aneurysm, developmental delay, and with poorly visualized coronary arteries during angiography, the diagnosis of supravalvular aortic stenosis or Williams syndrome should be considered.

ABSTRACT

Endovascular aneurysm repair (EVAR) is an established therapy to prevent rupture in large infrarenal abdominal aortic aneurysms (AAA). As experience with this therapy has grown, treatment of more challenging anatomy has led to the identification of several new procedurally related complications. We report the case of a 67-year-old man with an asymptomatic, large infrarenal AAA with an associated left common iliac artery aneurysm. Endovascular therapy for an aortoiliac aneurysm involved prior coil embolization of his left internal iliac artery to allow conventional EVAR with extension to the external iliac artery of the left graft limb, thus excluding the left iliac aneurysm. He presented 6 weeks postoperatively with onset of left-sided scrotal pain and underwent emergency orchidectomy for ischemic infarction of his left testis. The histology report confirmed that the left testis was necrotic secondary to a thrombus in the testicular artery. To our knowledge, this is the first report of testicular infarction after EVAR.
