Summary
Colon cancer is one of the most common solid tumours in western society. The usual initial treatment is excision of the cancer by an operation done through a cut down the midline of the abdominal wall. Over the past 10 years, minimally invasive technology has changed the approach to many surgical operations. A good example of this is an operation to remove the gall bladder. This is now routinely done using a laparoscope (telescope) which is introduced at the umbilicus.

The usual initial treatment is excision of the cancer by an operation done through a cut down the midline of the abdominal wall. Over the past 10 years, minimally invasive technology has changed the approach to many surgical operations. A good example of this is an operation to remove the gall bladder. This is now routinely done using a laparoscope (telescope) which is introduced at the umbilicus. An image on a video screen of the gall bladder is then used to guide instruments to remove the gall bladder without making a large incision in the abdominal wall. This is called a laparoscopic cholecystectomy. The safety of a laparoscopic assisted approach in the removal of colon cancer is yet to be determined. This study will compare the long term and short term outcomes of people who have colon cancers removed either by a laparotomy (a cut in the midline of the abdominal wall) or by a laparoscopic assisted approach (telescope).Read moreRead less

Summary
The liver is the main organ in the body for the metabolism and biliary excretion of natural and foreign solutes. Various liver diseases such as cirrhosis, alcoholic liver disease, diet and drug induced fatty livers can affect the uptake and metabolism of drugs and their suitability- dosing needs. Some liver diseases such as fatty livers are very common but how rapidly drugs are metabolised in these patients is not well described.

Various liver diseases such as cirrhosis, alcoholic liver disease, diet and drug induced fatty livers can affect the uptake and metabolism of drugs and their suitability- dosing needs. Some liver diseases such as fatty livers are very common but how rapidly drugs are metabolised in these patients is not well described. The work is important as it may help us better design new drugs and better choose which drugs to give and, if so, in what doses. In addition, many liver diseases require a biopsy for a definite diagnosis of the likely function of the liver. Estimation of liver function is particularly important in estimating whether there will be sufficient reserve on resection of a cancer or deciding if a liver transplant is needed. The liver is also a very complex organ which can trap or breakdown solutes by a range of different systems. Also of importance is how those diseases affect drug disposition in the liver given that an altered hepatic drug disposition may affect systemic response to the drugs and their metabolites. This work seeks to answer these questions.Read moreRead less

The Department of Gastroenterology and Clinical Nutrition at the Royal Children's Hospital has gained recognition as a national centre of excellence for the management of infants and children with SBS and intestinal failure. Due to the significant personal and heath-care burden related to SBS there has been an urgent need to improve understanding about the process of intestinal adaptation following massive small bowel resection (MSBR) in order to develop new treatments aimed at improving clinical outcome for patients with SBS. Over the past 5 years we have developed a preclinical model for the study of intestinal adaptation in infants using the juvenile pig. Our recent studies in this model have revealed that elemental formula is inferior to whole protein formula suggesting that the current clinical recommendations need urgent re-evaluation. Using the preclinical model in this proposal, we aim to define the mechanisms underlying the adaptive response and evaluate novel therapies aimed at enhancing adaptation following MSBR. Supplementation of enteral feeds with bovine colostrum isolate resulted in normal growth in the preclinical model despite MSBR. In this proposal we plan to advance this observation for the first time to human clinical trials in infants with SBS. Even small gains in enteral tolerance during the early post-operative period may have a significant impact on morbidity and mortality of children with SBS due to parenteral-nutrition related liver disease and gut-related sepsis. This research proposal provides a unique link between studies aimed at providing the scientific basis for understanding the mechanisms of intestinal adaptation using an established preclinical model and translating the results of these studies onto human trials, taking advantage of the clinical expertise available in the management of children with SBS.Read moreRead less
