Identifying the needs for teaching fundamental knowledge of laparoscopic surgery: a cross-sectional study in Japan.

<bold>Background: </bold>Recently, laparoscopic surgery (LS) has become a more common procedure than traditional open surgery. Although LS-related adverse events have been reported, there is no formal, standardized curriculum to teach the fundamentals of LS in Japan. Understanding surgeons' knowledge regarding LS is crucial for developing an educational curriculum. The purpose of this study was to determine the baseline knowledge on LS of surgeons and surgical trainees in Japan.<bold>Methods: </bold>Participants completed 24 multiple-choice questions testing basic cognitive knowledge of LS and a questionnaire regarding the status of laparoscopic education. The examination was developed according to the 13 content domains of the Fundamentals of Laparoscopic Surgery (FLS) program. Scores were compared between post-graduate year (PGY) > 5 and PGY 1-5 participants. Data are expressed as median scores and interquartile ranges. Wilcoxon signed-rank test was used for statistical analysis.<bold>Results: </bold>A total of 195 surgeons and surgical trainees from 10 teaching hospitals (PGY1-5: 66, PGY > 5: 129) across Japan completed the examination. The median score in the entire cohort was 75 [67; 83] %, with significantly higher scores in the PGY > 5 group compared to the PGY1-5 group (79 [75; 83] % vs. 67 [58; 75] %, p < 0.001). The differences in performance were due to better scores for PGY > 5 group on the sections "equipment," "patient considerations," "abdominal access," "tissue handling," "hemorrhage and hemostasis," "tissue approximation," and "exiting the abdomen." Overall, the median scores in the "energy sources" and "establishment and physiology of the pneumoperitoneum" subsections were lower than in other domains. All participants agreed on the need for fundamental knowledge and a formal educational curriculum.<bold>Conclusions: </bold>Compared to experienced surgeons, surgical trainees had lesser knowledge about performing LS. Regardless of the years of experience, there are crucial knowledge gaps in specific areas regarding safe LS that should be addressed by implementing an educational curriculum. [ABSTRACT FROM AUTHOR]
