00:01 In this very brief lecture, I’m going to review gastroschisis and omphalocele. 00:07 These are the kinds of problems that can show up on exam and that you need to know they exist. 00:12 But generally, exams won't have too much there in about what you have to know about them. 00:16 So I’ll try and review the important information and make this brief. 00:21 So an omphalocele is a midline abdominal wall defect as you can see here. 00:28 The viscera is still in the peritoneal sac. 00:31 This happens in roughly 1 in 5,000 babies. 00:34 So it’s rare, but most largest birthing centers will see one or two a year. 00:40 There are associated anomalies in half of these babies. 00:44 So we should call a geneticist in many cases. 00:47 They may have cardiac anomalies, renal anomalies, skeletal anomalies or even neural tube defects like anencephaly or spina bifida. 00:59 The prognosis varies depending on really the other anomalies. 01:04 The intestinal material can be usually surgically repaired without too much trouble. 01:10 This is compared to the gastroschisis. 01:14 A gastroschisis is a full thickness defect in the abdominal wall. 01:20 The intestinal material is hanging out of the abdomen. 01:24 There is an evisceration of bowel and in this case, there is no covering membrane. 01:30 This is less common. 01:31 It happens in roughly one in ten thousand births. 01:34 Maybe one birth a year in large birthing center. 01:39 These patients have associated defects in a smaller percent of the time, about 10% of the time. 01:45 They may have intestinal atresia or duplication. 01:49 They may have undescended testes. 01:52 These patients have an excellent prognosis if it’s a small defect. 01:57 If it’s a large defect, these infants can run into run some trouble. 02:03 Small defects are generally reduced and have a primary closure, they just sew it up. 02:09 But large defects require a gradual reduction over three to ten days. 02:15 These kids may have other symptoms too such as respiratory distress or need other things in the neonatal intensive care unit. 02:23 So great care has to be provided. 02:26 Surgeons use a silo to gradually reduce gastroschsis. 02:31 So that’s my quick summary of gastroschisis and omphalocele. 02:36 Thanks for your attention.
The lecture Gastroschisis and Omphalocele by Brian Alverson, MD is from the course Neonatology (Newborn Medicine).

Short lecture but excellent as it is presented in a way that is very easy to remember (presentation, frequency).
