Leakage of feces from the stoma area for a day or two may be related to factors such as poor connection of the stoma bag, edema of the stoma, and untimely replacement of the stoma bag. 1. Insecure connection of stoma bag: After the stoma surgery, the stoma bag will be connected to the stoma area in order to receive the intestinal feces. If the stoma bag is not firmly attached and cannot fit tightly with the skin of the abdominal wall, it may lead to leakage of feces. It is necessary for the patient to use the stoma bag correctly under the guidance of the doctor. 2. Ostomy edema: If the patient does not pay attention to cleaning the stoma area, or if the stoma area tissue is edematous due to other reasons, the use of the stoma bag may also lead to local fecal leakage. It is necessary to go back to the hospital as soon as possible for review and regular medication to ensure the recovery of the wound. 3. Failure to change the ostomy bag in time: If the patient does not change the ostomy bag in time, more feces in the bag or the ostomy bag can not be tightly fitted with the skin may lead to fecal leakage. It is necessary to change the stoma bag in time to maintain local hygiene and cleanliness to reduce the occurrence of fecal leakage.
