Jejunal atresia is a rare congenital condition that affects the small intestine, specifically the jejunum. It occurs when there is a blockage or absence of a portion of the jejunum, leading to significant digestive complications. The symptoms of jejunal atresia can vary depending on the severity of the condition, but there are several common signs to be aware of.
One of the primary symptoms of jejunal atresia is abdominal distension, which refers to a swollen or bloated abdomen. This occurs due to the accumulation of gas and fluid in the intestines, resulting from the obstruction caused by the atresia. The distended abdomen may appear visibly enlarged and feel firm to the touch.
Infants with jejunal atresia often experience frequent episodes of vomiting. The vomit may be greenish or yellowish in color, indicating the presence of bile. Vomiting occurs as a result of the blockage in the jejunum, preventing the normal passage of food and digestive juices through the intestines.
Meconium is the dark, sticky stool that newborns typically pass within the first 24 to 48 hours after birth. In cases of jejunal atresia, the blockage in the jejunum can prevent the passage of meconium. This can lead to a delay in the passage of stool or a complete inability to pass stool, known as meconium ileus.
Infants with jejunal atresia may experience abdominal pain or discomfort. This can manifest as irritability, crying, or a general sense of unease. The pain is caused by the obstruction in the jejunum, which can lead to distension and increased pressure within the intestines.
Due to the blockage in the jejunum, infants with jejunal atresia may have difficulties with feeding. They may show signs of decreased appetite, have trouble latching onto the breast or bottle, or experience discomfort during feeding. In severe cases, they may be unable to tolerate any oral intake and require intravenous nutrition.
If left untreated, jejunal atresia can lead to weight loss and failure to thrive in affected infants. The obstruction in the jejunum prevents the proper absorption of nutrients, leading to inadequate nourishment. This can result in poor weight gain, stunted growth, and overall failure to thrive.
If you suspect that your child may have jejunal atresia based on these symptoms, it is crucial to seek immediate medical attention. Jejunal atresia requires surgical intervention to remove the blockage and restore normal intestinal function. Early diagnosis and treatment can significantly improve the prognosis and long-term outcomes for affected infants.
