BACKGROUND The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) is an objective and appropriate scoring system for risk-adjusted comparative general surgical audit. This score was devised in the UK and has been used widely, but application of POSSUM to centres outside the UK has been limited, especially in(More)
Despite the increasing number of patients with the human immunodeficiency virus (HIV) infection, surgical experience with these patients remains limited. A retrospective review over a 9 year period (January 1985 to December 1993) was undertaken to determine the indications, operative management, pathologic findings and outcome of major abdominal surgery in(More)
BACKGROUND A consecutive series of 269 cases of bleeding gastric ulcer were studied prospectively from 1979 to 1993 inclusive. METHOD Fifty-five (21%) had a giant gastric ulcer with a diameter of 3 cm or more. These cases were compared with those with ulcers less than 3 cm in diameter in terms of clinical details, prognostic factors, urgent operation and(More)
Abdominal aortic aneurysm (AAA) repairs represent a significant workload in vascular surgery in Asia. This study aimed to audit AAA surgery and evaluate the application of the Portsmouth Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (P-POSSUM) in an Asian vascular unit for standard of care. Eighty-five consecutive(More)
BACKGROUND Abdominal aortic aneurysms (AAA) are common in the Caucasian population. Apart from reported differences in the occurrence of AAA in the black and white populations, there are few studies on the incidence of AAA in the Asian population. METHODS A prospective database of all patients with AAA seen between 1996 and 1999, in the South-East Asian(More)
Historically, Streptococcus pyogenes was a common cause of endocarditis and infected aortic aneurysm. Today, endovascular infections due to this organism have become exceedingly rare. We report the first case of aortic aneurysm infection due to S. pyogenes treated with initial endoluminal repair, review previous reports and discuss current treatment options.
BACKGROUND Pancreas-kidney transplantation is currently the most effective method to re-establish euglycaemia in insulin-dependent diabetics with associated renal failure. The standard technique employed has been bladder drainage of exocrine secretions coupled with systemic venous drainage ('systemic-bladder' (SB) drainage). The more physiological(More)
BACKGROUND Abdominal aortic aneurysms (AAA) repairs are routine operations with low mortality in the developed world. There are few studies on the operative management of AAA in the Asian population.This study reports the initial results from a unit with no previous experience in this surgery by a single surgeon on completion of training. METHODS All(More)
AIM Nocardia infections are an uncommon but important cause of morbidity and mortality in renal transplant recipients. The present study was carried out to determine the spectrum of Nocardia infections in a renal transplant centre in Australia. METHODS A retrospective chart analysis of all renal transplants performed from 2008 to 2014 was conducted to(More)
Comparative surgical audit to monitor quality of care should be performed with a risk-adjusted scoring system rather than using crude morbidity and mortality rates. A validated and widely applied risk adjusted scoring system, P-POSSUM (Portsmouth-Physiological and Operative Severity Score for the enUmeration of Mortality) methodology, was applied to a(More)
