Published by BMJ. Vaginal pessary is a practical and effective tool for pelvic organ prolapse management. Nevertheless, serious complications can occur in neglected patients such as vesicovaginal and rectovaginal fistula, erosion and impaction in adjacent structures. We report a case of neglected pessary found in the uterine cavity. The patient was treated with abdominal hysterectomy with in situ doughnut pessary. Proper pessary care and regular follow-up should be emphasised among patients, caregivers and related healthcare personnel to early detect as well as to avoid complications.Mahidol UniversityMedicineArticleSCOPUS10.1136/bcr-2018-228415
