The role of the human camera holder during laparoscopic surgery keeps valuable personnel from other duties. EndoAssist is a robotic cameraholding device controlled by the operator’s head movements. This study assesses its introduction into clinical practice. Ninety-three patients undergoing laparoscopic cholecystectomy were randomized to have either the(More)
Important physiological changes occur after major abdominal surgery. Cellular and morphological changes follow a period of malnutrition. Enteral feeding is an important strategy for maintaining gut integrity and function. Controversies remain on the use of feeding jejunostomy after major abdominal surgery and its use had not gained widespread acceptance.(More)
INTRODUCTION This observational study was carried out to establish how surgeons performing laparoscopic cholecystectomy currently deal with the issue of spilled gallstones. MATERIALS AND METHODS A questionnaire was circulated amongst laparoscopic surgeons attending the annual conference of the Association of Laparoscopic Surgery of Great Britain and(More)
Many colorectal procedures can be performed laparoscopically and frequently involve the formation of a stoma. This study aims to demonstrate whether there is an association between stoma complications and the operative technique: laparoscopic or open. A review was conducted of all patients undergoing stoma formation at a single center throughout 2009.(More)
BACKGROUND Few data exist on the physiological aspects of pig-to-primate renal xenotransplantation. METHODS Use of organs transgenic for human decay accelerating factor has allowed assessment of the metabolic and hormonal functions of these xenografts. RESULTS Porcine renal xenografts largely maintain plasma electrolyte homeostasis. An increase in(More)
A questionnaire was given to 37 members of staff of the Department of Surgery, Addenbrooke's Hospital, Cambridge, in order to determine whether their knowledge was adequate to give accurate information to patients regarding operations and thus to obtain properly informed consent for that operation. Each participant was asked to estimate the 24-h and 30-day(More)
BACKGROUND XT using the pig as a donor species may provide a potential solution to the lack of human organs available for transplantation. However, two major immunological obstacles have impeded the survival of porcine organs transplanted into primates. The first is hyperacute rejection (HR), which is a consequence of the recipient's preformed antibodies(More)
The increased survival of hDAF pig-to-primate renal xenografts for up to two months has afforded the opportunity to study physiological aspects such as organ growth. Experimental evidence exists of species restriction of the activity of growth hormone, although growth itself is also controlled by a number of other endocrine, paracrine and autocrine(More)
