In order to better secure the ostomy bag, patients with an ostomy usually need to wear a lap band. A stoma is a fistula that connects the intestines to the abdominal wall for patients with bowel irregularities for various reasons, ensuring that the patient can have normal bowel movements. Some patients undergo fistula reduction surgery after their basic condition is stabilized. Clinically, fistulas are mostly performed on the abdominal wall of the colon. In order to accept the feces in the intestine, an ostomy bag is attached to the fistula site to receive the feces. After the ostomy bag is attached, a lap band is often used to secure the ostomy bag and prevent it from detaching. Therefore, patients undergoing fistula surgery generally need to wear a lap band while wearing an ostomy bag. Nowadays, medical devices are updated frequently, if the patient’s bowel movement is relatively small, you can also use the snap type ostomy bag, in this case, it is also possible not to use the abdominal band. However, it is still recommended to wear a lap band for better fixation of the ostomy bag.
