Abstract

AbstractAimLow anterior resection syndrome (LARS) causes devastating symptoms and impairs quality of life (QOL). Although its incidence and risk factors have been reported, these data are scarce in Japan. This study aimed to elucidate the incidence and risk factors of LARS as well as to evaluate its association with QOL in Japanese patients.MethodPatients with anal defecation at the time of the survey between November 2020 and April 2021 were included, among those who underwent anus‐preserving surgery for rectal tumors between 2014 and 2019 in tertiary referral university hospital. The severity of LARS and QOL were evaluated with the LARS score and the Japanese version of the fecal incontinence quality of life scale (JFIQL), respectively. Primary endpoint was the incidence of major LARS. Secondary endpoints were risk factors and association with JFIQL.ResultsOf 332 eligible patients, 238 (71.7%) answered the LARS survey completely. The incidence of major LARS was 22% overall, and 48% when limited to lower tumors. Independent risk factors included lower tumors (OR: 7.0, 95% CI: 2.1–23.1, p = 0.001) and surgical procedures with lower anastomoses (OR: 4.6, 95% CI: 1.2–18.5, p = 0.03). The JFIQL generic score correlated moderately with the LARS score (correlation coefficient of −0.65). The JFIQL generic score was also significantly lower in lower tumors.ConclusionsThe incidence of major LARS is 22% in Japanese patients, and independent risk factors include lower tumors and surgical procedures with lower anastomoses. More severe LARS is associated with worse QOL which is significantly more impaired in patients with lower tumors.
