This thesis utilises an established small animal model to investigate the aetiology of port site metasrases and the efficacy of preventative strategies in reducing tumor implantation following laparoscopy. / Thesis (Ph.D.)--University of Adelaide, Dept. of Surgery, 2000?

Explores the factors affecting the movement of tumour cells from a primary malignancy across the peritoneal cavity to the port-site following laparoscopic intervention. Filter methods and radio-labelled tumour cells provided the most useful way of following cell movement. Concludes spread of tumour cells to the port-site is more likely in the presence of disseminated disease, as well as with inappropriate surgical technique. Metastasis may be reduced by the use of intraperitoneal lavage and appropriate surgical technique.

O objetivo deste trabalho foi avaliar os efeitos de sucessivas sessões de aspirações foliculares na quantidade, qualidade e capacidade de maturação in vitro de oócitos obtidos de ovelhas submetidas à estimulação hormonal prévia (80 mg FSH + 300 UI eCG). Foram selecionadas seis ovelhas (n=6) da raça Santa Inês, as quais foram submetidas a nove sessões de aspiração folicular por vídeolaparoscopia com intervalo de sete dias, totalizando 56 aspirações. Ao final do período de cultivo de 24 horas, os oócitos foram corados e classificados quanto ao estádio de maturação nuclear e citoplasmática. A taxa de recuperação foi de 61,4±2%, observando-se ausência de variação entre as sessões (p>0,05), e a média de oócitos recuperados por fêmeas de 6,4±2 por semana, com um total de 249 oócitos recuperados, sendo a média de 42±4 oócitos por fêmea no total das apirações. Não houve diferença significativa entre a classificação da maturação nuclear (p=0,937), mas sim entre a maturação citoplasmática (p<0,0001), entretanto não foi observado variação estatística entre as semanas quanto a maturação nuclear (p=0,908) e a maturação citoplasmática (p=0,792). Concluímos que após nove sessões consecutivas de aspiração folicular o número e a qualidade dos oócitos recuperados permaneceram constantes assim como as taxas obtidas de maturação nuclear e citoplasmática, demonstrando a viabilidade desta técnica para repetidas aspirações foliculares em uma mesma doadora / The success of in vitro production requires an effective collection technique as well as an efficient oocyte recovery. In addition, the best results have been applied for using laparoscopic aspiration. The aim of the present study was to evaluate if successive follicle aspiration sessions may interfere on quantity, quality and in vitro maturation of oocytes recovery from ewes submitted to hormonal stimulation. Santa Ines ewes (n=6) were submitted to a total of nine sessions (one session per week) of follicle aspiration performed by videolaparoscopy. The oocytes from each session were classified in according to quality and to in vitro maturation capacity. Nuclear and citoplasmatic maturation were assessed. The recovery rate was 61,39±19,97%, with no variation among the sessions (p>0,05) and the mean of recovered oocytes per ewe was 6,36±2,0 per week. There was no significant difference among nuclear maturation classification (p=0,937), but there was significant difference among citoplasmatic maturation (p<0,0001). There was no statistical variation among weeks to nuclear maturation (p=0,908), neither to citoplasmatic maturation (p=0,792). We could conclude that after nine consecutive sessions of follicle aspiration the number and quality of the recovery oocytes were constant, as well as nuclear and citoplasmatic maturation rates. Therefore, laparoscopic recovery of oocytes is a viable technique for repeated follicle aspiration in the same donor

Background: Considerable resources have been invested in low and high fidelity simulators in surgical training. The purpose of this study was to establish construct and predictive validity for the Fundamentals of Laparoscopic Surgery (FLS, low fidelity box trainer) and LapVR (high fidelity virtually reality) training systems and to establish construct validity for two operative ratings scales (GOALS and OSATS) in our center. Methods: 26 participants performed tasks from the FLS program and the LapVR simulator as well as a human laparoscopic cholecystectomy. Performance was evaluated using FLS and LapVR metrics, and the previously validated global rating scales. Results: GOALS and OSATS demonstrated construct validity. Construct and predictive validity was also strongly demonstrated for FLS tasks but only indeterminately for LapVR. Conclusions: The high cost LapVR remains experimental in resource constrained training programs. Efforts should be focused on utilizing the well-validated, lower cost FLS video trainer for assessment of laparoscopic skills.
