GASTROSQUISE ONFALOCELE PDF

Tojara The specific cause of this condition remains unknown, however there are some factors that are thought to increase the risk of having a baby with gastroschisis: Summary — Gastroschisis vs Omphalocele: Abdominal wall defects are uncommon, and gastroequise is more common than Omphalocele: However, when that does not happen and the intestines remain in the umbilical cord, the Omphalocele occurs. The primary approach is indicated for small omphaloceles. Very rarely, other organs may also gastrosquide out, such as stomach and liver. In gastroschisis, the herniated organs are not covered by a protective sac. Additionally, omphalocele is a characteristic of many genetic syndromes: You are commenting using your Facebook account. Right after birth, a plastic pouch or a mesh is used to contain the herniated organs gastroschisis or the sac omphalocele.

Imaging differential diagnosis Epidemiology The estimated incidence is at around per 10, live births. There may be a male predilection and an increased incidence with younger maternal age. Pathology This anomaly does not have a surrounding membrane unlike an uncomplicated omphalocele. It is the small bowel that herniates most often. The defect is invariably on the right side and usually measures between cm.

There is no covering membrane or membrane remnant. Content The small intestine always herniates through the abdominal wall defect and lacks normal rotation and fixation to the posterior abdominal wall. In addition to the small intestine, the large intestine, stomach, portions of the genitourinary system and liver may herniate through the defect as well.

Etiology A compromise in vascular supply to the area in the abdominal wall adjacent to the umbilicus may be a causative factor. Some also suggest an incomplete regression of the right umbilical vein as a possible causative factor.

Genetics Most cases have a sporadic occurrence. Associations Associated anomalies are rare with gastroschisis unlike with an omphalocoele except for related bowel abnormalities i. This causes the fetal abdominal circumference to be smaller than expected for gestation age. The herniated bowel often appears free-floating rather than contained. The herniated bowel wall can be thickened due to edema. The condition of the bowel at birth is the single most important prognostic factor.

Antenatal diagnosis of gastroschisis may facilitate a planned delivery in a specialized unit tertiary care center with parental counseling as well as surgical planning. Most infants are treated surgically on the first day of life. In general, it carries a good survival rate post surgery 3. Some state that the smaller the gastroschisis, the greater the risk of ischemia to the herniated gut due to a more severe restriction of blood flow.
