OBJECTIVES To study the incidence of and factors associated with single-vehicle rollover (SVRO) accidents in the "Top End" of the Northern Territory (NT); to identify factors associated with major injury and death from SVRO accidents. DESIGN Retrospective analysis of records from the NT Department of Transport and Works' police database, Royal Darwin(More)
T-tube drainage of the common bile duct (CBD) following duct exploration has become standard surgical practice. This randomized prospective study has compared primary closure versus T-tube drainage of the CBD following exploration for calculous disease. Thirty-seven patients underwent primary closure and 26 underwent closure over T-tube. Both groups were(More)
A variety of conservative and surgical options are available in the management of para-oesophageal hiatus hernia. However opinion is divided in regard to the best form of treatment. A series of 71 patients with para-oesophageal hiatus hernia has been studied, to assess hospital management and outcome after treatment. Case notes of all patients were(More)
BACKGROUND Due to the geographical remoteness of Darwin, which has no resident neurosurgeon, emergency transfer of patients for neurosurgery is usually impractical. In Darwin emergency neurosurgery must be undertaken by general surgeons. METHODS Data from the operating theatre, Emergency Department and Intensive Care Unit were prospectively recorded on(More)
The role of the pylorus in the control of gastric emptying of liquids and digestible solids was investigated in the present study by pylorus excision in six pigs. The pylorus was left intact in another six pigs. Antro-pyloro-duodenal motility was recorded by a sleeve sensor and side holes. Liquid emptying was significantly more rapid in pylorus excised than(More)
We have investigated the role of ascending duodenal intramural nerves in the control of isolated pyloric pressure waves (IPPW) and liquid gastric emptying. In six pigs, the proximal duodenum was transected to interrupt intramural nerves. A further six pigs had a sham operation. Four weeks after operation, motility of the antrum, pylorus, and duodenum was(More)
1. In six conscious pigs antral, pyloric and duodenal pressures were recorded with a 5.5 cm sleeve sensor and multiple perfused side holes. The manometric assembly was positioned by dual point transmucosal potential difference measurement. Gastric emptying was measured by drainage of the proximal duodenum through a Thomas cannula. Pressures were correlated(More)
Because of the paucity of adequate training models for laparoscopic common bile duct exploration, a live porcine training model was developed and evaluated. This model requires preliminary laparoscopic ligation of the distal bile duct 7–14 days prior to utilization. It aids the development of skills for laparoscopic common bile duct exploration and should(More)
BACKGROUND Royal Darwin Hospital (RDH) is the only major hospital for the 'Top End' of Northern Territory and Western Australia. As retrieval distances exceed 2600 km, resident generalist surgeons undertake all emergency neurosurgery. METHODS Retrospective clinical study from RDH records and review of prospectively collected datasets from RDH Intensive(More)
BACKGROUND This study has investigated first the role of the antrum and pylorus in the retardation of gastric emptying during distension of the duodenum, and second whether ascending duodenal intramural nerves contribute to control of both antro-pyloric motility and liquid gastric emptying in response to distension of the duodenum. METHODS Studies were(More)
