Meconium Ileus

If your baby has only meconium ileus and not a more complex problem, the surgeon will first try to wash out the blockage with an enema guided by X-rays. 

• In this procedure, a radiologist will place a tube (catheter) in your baby’s rectum.
• X-ray dye (dilute contrast) will slowly be put through this tube into your baby’s large intestine (colon).
• The radiologist may also use warm saline. This may be enough to clear the blockage. 

If the entire blockage does not wash out the first time, the surgeon and radiologist may perform enemas again over the next 1 to 2 days, depending on how your baby is doing.

If enemas do not work, your baby will need surgery to remove the blockage. At the time of surgery, we give your baby medicine to make them sleep without pain (general anesthesia).

The surgeon makes a cut (incision) near the belly button. There are many ways to take care of meconium ileus. Your surgeon will decide which method is best for your baby while doing the surgery. The surgeon may be able to wash out the meconium. But some babies will need to have a segment of their intestine removed (resection) or to have an ostomy (pronounced OST-uh-mee).

The surgeon removes the segment of intestine that is blocked and any segment that was damaged by the blockage. (Usually when the intestine is perforated, the surgeon must remove that segment.)

If the rest of the intestine is healthy enough, the surgeon sews the 2 open ends of the intestine back together (primary anastomosis, pronounced an-as-toe-MOE-sis) and closes the incisions. In many cases, the baby needs an ostomy instead.

The surgeon brings the 2 open ends of the intestine to the surface of the baby’s belly and attaches them to openings (stoma) made in the wall of the belly. Sometimes only 1 ostomy is needed. In this case, the surgeon attaches 1 of the open ends to the side of the other open end. Then the surgeon brings just the remaining open end to the surface of the belly.

After surgery, the surgeon may try to soften and wash out the blockage with liquid. This depends on how much meconium had to be left in the intestine. Liquid can be put through a tube that passes through your baby’s nose to their stomach (NG tube) or through a tube inserted in your baby’s rectum or ostomy. The surgeon may use medicine called acetylcysteine to help soften and move the meconium.

A bag can be attached to the ostomy to collect waste from the intestine. If your child needs an ostomy, we will teach you how to care for the stoma.

After the blockage is cleared, the surgeon performs another surgery weeks or months later to close the ostomy and to sew the ends of the intestine together. The baby is usually able to go home with the ostomy before the second surgery.

After surgery, your baby will stay in our Level IV Neonatal Intensive Care Unit (NICU), where they get the high level of care they need. Seattle Children’s is the first hospital in Washington to have a Level IV NICU. When they’re ready, they move to a regular hospital room and, eventually, home.

The length of hospital stay varies, but is usually at least a few weeks and often longer. The time frame depends mostly on how long it takes your baby to start eating again and gaining enough weight.

After surgery, your baby will need feedings through a tube that goes into a large vein (central line). When their intestines start to work, most babies need an NG tube or OG tube. Some will be able to eat by mouth instead of having an NG or OG tube. Your doctor will talk with you about the feeding method that is best for your baby.

We will give your baby pain medicine to make them comfortable.

The surgeon will stay closely involved with your baby’s care while they are in the hospital. When your baby goes home, the surgeon will schedule a follow-up visit. At the follow-up visit, the surgeon will make sure that the incision is healing and your baby is gaining weight and growing as they should.

If your baby has cystic fibrosis, lung doctors (pulmonologists) who treat this disease will be a part of your baby’s care and will provide long-term follow-up for many years.

We do more minimally invasive procedures on children for a broader range of conditions than any hospital in the region. After this type of surgery, your child is likely to heal faster with less pain and go home from the hospital sooner.

Children react to illness, injury, pain and medication differently than adults. They require – and deserve – care designed specifically for them. Our pediatric experts understand how treatments today affect growing bodies in the future and are specially trained to meet the needs of children and teens.

We provide the right care, at the right time. We are committed to avoiding unnecessary diagnostic tests, radiation and surgery. Radiation doses at Seattle Children’s are consistently lower than the guidelines recommended by the American College of Radiology.

Seattle Children’s is 1 of just 5 hospitals nationwide whose commitment to preventing and relieving kids’ pain has been recognized by ChildKind International.

When it comes to your child’s health, experience matters. Our surgical teams have the skills to do it right the first time, to handle the unexpected and to care for children with the rarest conditions. We also have experience dealing with other problems that may look like meconium ileus, such as meconium plug and small left colon syndrome.

More cases mean greater surgical expertise and a sharper ability to determine if surgery is even necessary. All that adds up to better outcomes.

When you come to Seattle Children’s, you have a team of people to care for your child before, during and after surgery. Along with your child’s surgeon, you are connected with nurses, dietitians, child life specialists and others. We work together to meet all of your child’s health needs and help your family through this experience.

We work with many children and families from around the Northwest and beyond. Whether you live nearby or far away, we can help with financial counseling, schooling, housing, transportation, interpreter services and spiritual care. Learn about our services for patients and families.
