An ostomy device including a bag, a lid, and a vent. The lid is replaceably attached to the bag, attaches to a site of a stoma of a patient, and self-seals to the stoma of the patient. The vent is operatively connected to the bag, and vents gas emanating from the stoma of the patient to prevent build-up of the gas that could detach the ostomy device from the site of the stoma of the patient and require rettachments that could irritate skin of the patient at the site of the stoma of the patient.
