Impact of COVID-19 Outbreak on Stoma Surgery and Stoma Clinic Service: A Retrospective Study at a Single Japanese Referral Hospital.

Abstract

Aim The impact of the COVID-19 pandemic on medical practice has been frequently reported from Western countries, but there have been few studies in other areas, especially regarding stoma surgery and stoma care. Methods We investigated the numbers of all operations and stoma-related surgeries at our hospital in 2019 and 2020. The cumulative numbers of consultations at our ostomy clinic and patient population stratified by the period of having a stoma were compared between these calendar years. The frequency of ostomy clinic visit by individual patients within the first year after stoma creation and stoma-related complications per consultation were also analyzed. Results The number of elective surgeries decreased by approximately 10% from 2019 to 2020, but the numbers of stoma creation and closure procedures did not differ. The total numbers of consultations at our ostomy clinic were also similar between these years. However, the percentage of patients with a stoma for less than a year who visited our ostomy clinic increased from 49.7% in 2019 to 53.5% in 2020, whereas the visitation rate for other patients decreased. Moreover, patients with a stoma for less than a year visited the ostomy clinic more frequently in 2020 (0.42/month) than in 2019 (0.30/month, p=0.032). There were fewer grade 2 or more severe peristomal complications in 2020 (11% vs 17% in 2019, p < 0.001) at our ostomy clinic. Conclusion The COVID-19 outbreak led to a shift in the patient population at ostomy clinics of new stoma patients, which may have resulted in fewer peristomal complications.
