A large bowel obstruction occurs when part or all of your large intestine is blocked. As a result, waste can't move through your bowel correctly and out of the body. You must be treated right away to manage the blockage.
During a colostomy part of the colon (large intestine) is removed or disconnected. If the large intestine was diseased, it may be removed. If it was injured, it may be disconnected for a short time while it heals, then reconnected after a certain period of time.
An intestinal obstruction means that the small or large intestine is blocked at one or more spots. This prevents air, food, stool, and fluid from passing normally through the digestive system.
During an ileostomy, healthcare providers either remove or disconnect your colon (large intestine), and sometimes part of the last section of your ileum (last section of your small intestine).
