ABSTRACT Background We previously reported the gender disparities in surgical procedures between male and female surgeons using National Clinical Database covering more than 95% of all operations performed in Japan. This study aims to examine the changes in gender disparity in the surgical experience of gastrointestinal surgeons in Japan before and after implementation of measures by the Japanese Society of Gastrointestinal Surgery to address gender inequality commenced in 2021. Methods We conducted a nationwide retrospective study to compare the number of operations performed by male and female surgeons using National Clinical Database. The number of operations per surgeon was calculated based on every 2 years of a surgeon's experience, and a comparison was made between male and female surgeons. The years selected for analysis were 2015, 2019, and 2023. Results Almost no gender differences were observed in the number of low‐difficulty surgeries. For medium‐difficulty surgeries, the number performed by female surgeons showed an improving trend over the study period, yet some disparities remained. The number of high‐difficulty surgeries (low anterior resection and pancreaticoduodenectomy) performed by male surgeons was higher than the number performed by female surgeons, except for protrusions. This disparity remained unchanged over the study period. Conclusions The efforts of the Japanese Society of Gastrointestinal Surgery has been shown to be effective in mitigating gender disparities in the number of surgeries performed. High‐difficulty surgeries have emerged as the primary target for further improvement initiatives.
