This has renewed interest in the understanding of the basic principles of the molecular biology of colorectal carcinogenesis. The condition is characterised by multiple(More)
Barrett's oesophagus represents the replacement of stratified squamous epithelium by metaplastic columnar epithelium for 3 cm of the distal oesophagus. Gastro-oesophageal reflux, which affects 40% of the adult population, is the principal aetiological factor. This results in predominantly acid but also bile reflux (due to duodenogastrooesophageal reflux)(More)

INTRODUCTION The development of pancreatic infection is associated with the development of a deteriorating disease with subsequent high morbidity and mortality. There is agreement that in mild pancreatitis there is no need to use antibiotics; in severe pancreatitis it would appear to be a logical choice to use antibiotics to prevent secondary pancreatic(More)
Gastro-oesophageal reflux disease (GORD) is attributable primarily to acid and bile reflux through the lower oesophageal sphincter. Bile reflux has been implicated in severe oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma. Developments in evaluating and managing GORD and Barrett's are discussed, with their aetiological role in junctional(More)
A prospective study was undertaken to review the use of combined lumbar spinal and thoracic high-epidural regional anesthesia in high-risk patients who underwent gastrointestinal/colorectal surgery from 2004 to 2006. Twelve high-risk patients underwent 13 gastrointestinal/colorectal surgical procedures, using a regional anesthetic technique, which consisted(More)
