BACKGROUND The most common bariatric procedure in Australia is laparoscopic adjustable gastric banding (LAGB). Although successful, there is a substantial long-term complication and failure rate. Band removal and conversion to Roux-en-Y gastric bypass (RYGB) can be an effective treatment for complicated or failed bands. There is increasing evidence(More)
We reviewed the results of percutaneous intervention of hilar biliary malignancy over a 10-year period at a single institution: the Royal Melbourne Hospital. Ninety-nine patients (100 treated in total) were included. Information was retrieved by retrospective examination of patient notes and radiology, combined with interviews with family and relevant(More)
BACKGROUND Oesophageal malignancy is a disease with a poor prognosis. Oesophagectomy is the mainstay of curative treatment but associated with substantial morbidity and mortality. Although mortality rates have improved, the incidence of perioperative morbidity remains high. This study assessed the impact of postoperative morbidity on long-term outcomes. (More)
Synchronous tumours of the oesophagus and pancreatic head are very rare. This report describes a unique case of an adenocarcinoma of the distal oesophagus and a neuroendocrine tumour of the pancreatic head diagnosed synchronously but successfully managed metachronously. Initially, the patient underwent an oesophagectomy, with a colonic reconstruction(More)
Malignant strictures of the biliary tree are an uncommon cause of obstructive jaundice. There are a number of pathological subtypes, but tumours in this region tend to have similar clinical and diagnostic features and therapeutic and prognostic implications. We review the published literature on this topic discussing diagnostic modalities and treatment(More)
Idiopathic hypereosinophilic syndrome (HES) is an uncommon condition characterized by an unexplained elevation of absolute eosinophil count (AEC) to > or = 1.5 x 10(9)/l for at least six months, and is frequently associated with eosinophil-mediated end organ damage. Idiopathic HES, as with secondary HES and primary hypereosinophilic clonal hematopoietic(More)
INTRODUCTION Benign gastro-colic fistula is a rare occurrence in modern surgery due to the progress in medical management of gastric ulcer disease. Here we report the first case of benign gastro-colic fistula occurring whilst on proton-pump inhibitor therapy. This is a case study of benign gastro-colic fistula and review of the available literature in(More)
Greater curve plication is an emerging procedure for the treatment of morbid obesity. A median weight loss of up to 61% at one year has been reported in initial reports. Thus far, operative morbidity is low and there is no reported mortality. We present a case of gastric herniation after greater curve plication. Severe nausea and vomiting occurred in our(More)
OBJECTIVE Bile duct injury is an uncommon but potentially serious complication in cholecystectomy. A recognized treatment for minor biliary injury is internal biliary decompression by endoscopic retrograde cholangiopancreatography (ERCP) and stent insertion. The aim of this study was to assess the effectiveness of ERCP in the management of minor biliary(More)
