Indirect assessment of hemorrhoid incidence using invasive treatment data in Japan: A 5-year study based on nationwide health insurance claims.

ABSTRACT:

Aim

The epidemiology of hemorrhoids is challenging because of variability in sampling methodologies and diagnostic criteria across different studies. This study indirectly clarified the epidemiology of hemorrhoids by investigating the number of invasive treatments for hemorrhoids (ITH) using a nationwide healthcare claims database.

Methods

The annual number and rate of ITH procedures per 100 000 people during 2018-2022 were examined. ITH covered by the Japanese healthcare insurance includes sclerotherapy, rubber band ligation, infrared coagulation, thrombectomy, hemorrhoidectomy, and stapled hemorrhoidopexy. The demographic peak patterns in the sex- and age-stratified data were analyzed. Annual trends were evaluated using the Jonckheere-Terpstra trend test or Poisson regress
