    OBJECTIVE: To examine the prevalence trends of minimally invasive hysterectomy for benign indications in Japan and investigate regional disparities. STUDY DESIGN: A retrospective cohort and ecological study using "The National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) Open Data". SETTING: Nationwide Japan. PATIENTS: Individuals who underwent hysterectomy for benign indications from 2014 to 2020. INTERVENTIONS: Trend analysis of minimally invasive surgery (MIS) rates through laparoscopic hysterectomies (LH) and robotic-assisted laparoscopic hysterectomies (RA-LH) at the national and prefecture levels. Examination of regional factors contributing to the disparity in MIS implementation rates by second medical service area (SMSA). RESULTS: The number of LH has increased from 16,016 in 2014 to 27,755 in 2020. The nationwide MIS hysterectomy rate increased from 29% in 2014 to 55% in 2020 (p less than 0.001). More than 50% of hysterectomies have been performed as MIS since 2019. There was an increasing trend in MIS rates in all age groups. All prefectures except one showed a significant upward trend (p less than 0.05) in the MIS rates, but MIS rates varied widely (23-84%). In a multivariable model, the MIS was more likely to be performed in the SMSAs in western Japan (p = 0.011), in the SMSAs where the number of laparoscopy-qualified gynecologists is 5-10 (p = 0.013), and 11 or higher (p less than 0.001). CONCLUSIONS: This study reveals a shift towards minimally invasive surgery (MIS) in total hysterectomy procedures in Japan. However, significant disparities in the prevalence of MIS hysterectomy exist, potentially influenced by the number of laparoscopy-qualified gynecologists.
