Presentation Transcript

  1. Definition • Herniation of bowel loops & other abdominal organs through a defect in the abdominal wall w/ no associated covering /sac • Defect just to the right of the umbilical cord

  2. Embryology • During the 4th week of development, the lateral body folds move ventrally and fuse in the midline to form the anterior body wall. • Incomplete fusion defect that allows abdominal viscera to protrude through the abdominal wall. • The bowel typically herniates through the rectus muscle, lying to the right of the umbilicus.

  3. Risk Factors • High-risk pregnancies complicated by infection • young maternal age • Smoking / drug abuse • anything that contributes to low birth weight can increase the incidence of gastroschisis

  4. Differential Diagnosis ANTS & CLAUDING— may table form yung ddx see if pwede na o congested pa din Thanks!!! P.S. Same lang yung table at di table form Pili lang k..thanks again

  5. Omphalocele • a defect in the anterior abdominal wall with extrusion of abdominal organs. • covered by a membrane (consisting of an outer layer of amnion and an inner layer of peritoneum) with the cord inserting through these covering. • In contrast with gastroschisis there is a high association with other malformations and chromosomal abnormalities

  6. Congenital hernia of the abdominal wallan extra-abdominal mass on the right of the normal umbilical cord insertion. • Bladder extrophy: abdominal wall defect of the infra-umbilical region in which bladder mucosa is exposed. Ultrasound findings are absence of a fluid-filled intrapelvic bladder and a soft tissue mass seen at the lower abdomen. • Cloacal dystrophy: also known as OEIS complex: association of omphalocele, bladder extrophy, imperforate anus and spina bifida.

  7. Limb body wall complex (body stalk anomaly): a set of disruptive abnormalities characterized by a severe body-wall defect (thorax, abdomen or both), evisceration of the abdominal organs into an amnioperitoneal sac and a shortened or absent umbilical cord • Pentalogy of Cantrell: large abdominal wall defect characterized by omphalocele, ectopia cordis and disruption of the distal sternum, anterior diaphragm and diaphragmatic pericardium. It appears on ultrasound as a large thoracoabdominal wall defect containing the heart and much of the abdominal contents • Beckwith Wiedeman syndrome: omphalocele, organomegaly (liver, splenic and renal enlargement), macroglossia and polyhydramnios
