Abstract
in English, Portuguese

Objective: To assess the acquisition of basic laparoscopic skills of Medical students trained on a surgical simulator.

Methods: First- and second-year Medical students participated on a laparoscopic training program on simulators. None of the students had previous classes of surgical technique, exposure to surgical practice nor training prior to the enrollment in to the study. Students´ time were collected before and after the 150-minute training. Skill acquisition was measured comparing time and scores of students and senior instructors of laparoscopic surgery.

Results: Sixty-eight students participated of the study, with a mean age of 20.4 years, with a predominance of first-year students (62%). All students improved performance in score and time, after training (p<0,001). Score improvement in the exercises ranged from 294.1 to 823%. Univariate and multivariate analyses identified that second-year Medical students have achieved higher performance after training.

Conclusions: Medical students who had never been exposed to surgical techniques can acquire basic laparoscopic skills after training in simulators. Second-year undergraduates had better performance than first-year students.

Objetivo: Avaliar o aprendizado de habilidades laparoscópicas básicas em estudantes de Medicina submetidos a treinamento em um simulador.

Métodos: Estudantes de Medicina do primeiro e segundo ano participaram de um treinamento de exercícios de laparoscopia em simuladores. Nenhum estudante havia cursado a disciplina de técnica operatória ou teve exposição prévia a cirurgias ou treinamento cirúrgico. Os mesmos tiveram seu tempo coletado antes e após treinamento de 150 minutos. A aquisição de habilidade foi medida comparando tempo e pontuações dos alunos em relação a cirurgiões instrutores em cirurgia laparoscópica.

Resultados: O trabalho teve a participação de 68 alunos, com média de idade de 20,4 anos. Houve predomínio de alunos do primeiro ano (62%). Na comparação pré e pós-treino, todos os alunos obtiveram melhora de desempenho em pontuação e tempo dos exercícios, com significância estatística (p<0,001). A pontuação apresentou variação de melhora de 294.1 a 823%. Análise univariada e multivariada identificaram que alunos do segundo ano obtiveram um maior ganho de desempenho com o treinamento.

Conclusões: Estudantes de Medicina nunca expostos à técnicas cirúrgicas adquirem habilidades laparoscópicas básicas em treinamento sistematizado em simuladores. Alunos do segundo ano apresentaram melhor desempenho em relação a alunos do primeiro ano.
