A laparoscopia é uma técnica cirúrgica minimamente invasiva que tem sido amplamente utilizada em diferentes especialidades médicas. Nessa técnica, um pequeno dispositivo óptico é inserido no abdômen do paciente, permitindo ao cirurgião visualizar a cavidade abdominal e realizar procedimentos cirúrgicos com instrumentos especiais. A laparoscopia oferece vantagens em relação à cirurgia aberta, como menor dor pós-operatório, menor tempo de internação e retorno mais rápido às atividades normais. No entanto, a laparoscopia pode apresentar riscos, como lesões nos órgãos abdominais e complicações decorrentes da anestesia. Com o desenvolvimento de novas tecnologias, como a cirurgia robótica, a laparoscopia tem se tornado ainda mais avançada e eficiente.

The contamination of waterbodies is a worldwide concern due to the increasing urbanization and industrialization of the cities without good effluent management. Touristic cities can suffer with the number of people during high seasons periods, which can lead to an elevated use of natural resources and effluents discharges. Moreover, raining seasons, either high or low, can also play an important role in contaminating waterbodies once a dilution or concentration of contaminants may take place. The present study evaluated the water quality of the Tejereba River (Guarujá, Brazil) during the high season (January) and low season (March and May) in 2018. Reduction in water quality was observed in May, a month with low pluviosity and low tourism. The integrated data analysis (PCA) showed a positive correlation between the physicochemical parameters and the month of May, in which they were negatively correlated with pluviosity and the percentage of tourists. Despite the deterioration of water quality in May, no toxicity to Daphnia magna was observed. Our work showed that water quality (physicochemical and microbiological parameters), during the studied months, is more related to raining seasons than to the presence of tourists in Guarujá, Brazil.
