A bowel obstruction happens when either your small or large intestine is partly or completely blocked. The blockage prevents food, fluids, and gas from moving through the intestines in the normal way. The blockage may cause severe pain that comes and goes.
Tumors, scar tissue (adhesions), or twisting or narrowing of the intestines can cause a bowel obstruction. These are called mechanical obstructions.
In the small intestine, scar tissue is most often the cause. Other causes include hernias and Crohn's disease, which can twist or narrow the intestine. Or a tumor can block the intestine. A blockage also can happen if one part of the intestine folds like a telescope into another part. This is called intussusception.
In the large intestine, cancer is most often the cause. Other causes are severe constipation from a hard mass of stool and narrowing of the intestine caused by diverticulitis or inflammatory bowel disease.
Symptoms of a bowel obstruction include:
Your doctor will ask you questions about your symptoms, other digestive problems you've had, and any surgeries or procedures you've had in that area. He or she will check your belly for tenderness and bloating.
Your doctor may do:
Most bowel obstructions are treated in the hospital.
In the hospital, your doctor will give you medicine and fluids through a vein (IV). To help you stay comfortable, your doctor may place a tiny tube called a nasogastric (NG) tube through your nose and down into your stomach. The tube removes fluids and gas and helps relieve pain and pressure. You will not be given anything to eat or drink.
Most bowel obstructions are partial blockages that get better on their own. The NG tube may help the bowel become unblocked when fluids and gas are removed. Some people may need more treatment. These treatments include using liquids or air (enemas) or small mesh tubes (stents) to open up the blockage.
Surgery is almost always needed when the intestine is completely blocked or when the blood supply is cut off. You may need a colostomy or an ileostomy after surgery. The diseased part of the intestine is removed, and the remaining part is sewn to an opening in the skin. Stool passes out of the body through the opening and collects in a disposable ostomy bag. In some cases, the colostomy or ileostomy is temporary until you have recovered. When you are better, the ends of the intestine are reattached and the ostomy is repaired.
If your blockage was caused by another health problem, such as diverticulitis, the blockage may come back if you don't treat that health problem.
