Abstract

Abstract: Aim: We aimed to evaluate regional disparities in the proportion of the three main laparoscopic surgeries for benign gynecological diseases among 47 prefectures in Japan and their correlation with the number of laparoscopy‐qualified gynecologists per population. Methods: In this retrospective ecological study, we collected the data of patients from 47 prefectures in 2017 using "The National Database of Health Insurance Claims and Specific Health Checkups of Japan" Open Data from the Ministry of Health, Labor and Welfare in Japan. The primary outcome of the study was the proportion of laparoscopic surgeries conducted for benign gynecologic diseases (hysterectomy, myomectomy and surgery for the benign ovarian diseases). The main exposure was the number of laparoscopy‐qualified gynecologists per 100 000 females. Results: The average proportion of laparoscopic hysterectomies, myomectomies and surgeries for the benign ovarian disease were 38% (standard deviation (SD) 16, range 12–74), 48% (SD 18, range 9–81) and 60% (SD 11, range 36–79), respectively. Multiple regression analysis showed a significant correlation between the number of laparoscopy‐qualified gynecologists per 100 000 females and the proportion of the three main laparoscopic surgeries. Conclusion: There are obvious regional disparities in the proportion of the three main laparoscopic procedures for benign gynecological diseases among 47 prefectures. The number of laparoscopy‐qualified gynecologists correlated significantly with these regional disparities. The academic society should monitor these regional disparities and make an effort to reduce these regional disparities by increasing laparoscopy‐qualified gynecologists in areas where the widespread use of laparoscopic techniques is lagging.
