clinicalGJ tube is a better short-term solution than fundoplication for reflux in unrepaired omphalocele, with fundoplication performed at the time of definitive abdominal wall repair↗
▶Ep 7 · 48:08

clinicalDuring omphalocele reduction with liver, hepatic veins are very superficial and can be injured during fascial dissection if not careful↗

clinicalMetoclopramide (Reglan) can be given intravenously for gastroschisis hypomotility, unlike oral prokinetics where absorption is uncertain↗
▶Ep 34 · 25:02
clinicalA UK study showed cisapride helped gastroschisis patients achieve bowel function more quickly, but cisapride is no longer available↗
▶Ep 34 · 25:37
clinicalA randomized prospective trial is currently underway to determine if intravenous metoclopramide can shorten the period of hypomotility in gastroschisis↗
▶Ep 34 · 25:57
clinicalAt 4 weeks without bowel function, contrast enema is performed to look for mechanical obstruction, sometimes followed by upper GI if enema is inconclusive↗
▶Ep 34 · 26:44
clinicalIf still no bowel function at 6 weeks, laparotomy is typically performed, often finding adhesions which are taken down↗
▶Ep 34 · 27:21
opinionGoing in too early on gastroschisis patients with prolonged ileus is a mistake↗
▶Ep 34 · 28:03
clinicalIn gastroschisis, it's usually the right testis that is extruded, and in about half the cases it finds its way down into the scrotum after being reduced↗
▶Ep 34 · 28:43
clinicalOmphalocele has a much higher incidence of associated anomalies and chromosomal abnormalities compared to gastroschisis↗
▶Ep 34 · 28:59
clinicalKaryotype analysis and testing for Beckwith-Wiedemann syndrome are routinely performed for omphalocele patients↗
▶Ep 34 · 29:47
clinicalSmall omphaloceles without liver are more likely to be associated with abnormal chromosomes than large omphaloceles↗
▶Ep 34 · 30:05
clinicalFor small omphaloceles, there's no rationale for routine cesarean section, delivery at a perinatal center, or preterm delivery↗
▶Ep 34 · 30:23
clinicalSmall omphaloceles are simple to repair surgically↗
▶Ep 34 · 31:04
clinicalFor giant omphaloceles (defined as any omphalocele with a lot of liver out), most surgeons recommend cesarean section, though this is not evidence-based↗
▶Ep 34 · 31:42
clinicalGiant omphaloceles should be delivered at a perinatal center because they need a pediatric surgeon and experienced neonatologists↗
▶Ep 34 · 31:55
clinicalPulmonary hypoplasia is associated with giant omphaloceles and is very difficult to diagnose prenatally↗
▶Ep 34 · 32:09
clinicalSome giant omphalocele patients have severe pulmonary hypoplasia requiring early intubation and respiratory support↗
▶Ep 34 · 32:38
clinicalThe goal in omphalocele management is to reduce viscera without injury from direct trauma or increased intraabdominal pressure↗
▶Ep 34 · 33:14
clinicalIntraabdominal pressure monitoring is very helpful in omphalocele management↗
▶Ep 34 · 33:28
clinicalStuart Lacy established the guideline of keeping intraabdominal pressure below 20 mmHg based on rabbit studies in the 1980s, which showed improved outcomes in a prospective study in children↗
▶Ep 34 · 33:56
clinicalLacy also described an increase in central venous pressure of more than 4 as a concerning threshold↗
▶Ep 34 · 34:02
clinicalIntraabdominal pressure can be measured through the nasogastric tube or via Foley catheter measuring intravesical pressure↗
▶Ep 34 · 34:17
clinicalThe trend of pressure is more important than the absolute number during reduction↗
▶Ep 34 · 34:43
clinicalPrimary closure is attempted for full-term omphalocele patients without significant cardiac disease, respiratory issues, or pulmonary hypoplasia↗
▶Ep 34 · 35:07
clinicalThe Montreal group described using the omphalocele sac as a silo by sequentially ligating it over several days to allow abdominal wall stretching↗
▶Ep 34 · 35:44
clinicalSequential sac ligation requires a thick enough sac and umbilical cord insertion at the top rather than the side↗
▶Ep 34 · 37:34
clinicalUsing Duoderm to gradually reduce omphaloceles appears to achieve reduction more quickly than sac ligation↗
▶Ep 34 · 38:12
clinicalIndications for escharotic therapy include prematurity, severe cardiac disease, pulmonary hypoplasia, multiple anomalies, chromosomal abnormalities, or giant omphaloceles where reduction is not feasible↗
▶Ep 34 · 38:49
clinicalMushroom-shaped omphaloceles have a small abdominal wall defect but large external contents, making reduction impossible↗
▶Ep 34 · 39:26
clinicalSigy Ein had long experience using silver sulfadiazine (Silvadene) for escharotic therapy in omphaloceles↗
▶Ep 34 · 39:45
clinicalWith escharotic therapy, the omphalocele is painted with the agent, forms an eschar, eventually epithelializes, and is later repaired like a large ventral hernia↗
▶Ep 34 · 40:19
clinicalTiming of definitive omphalocele repair after escharotic therapy depends on the individual child, ranging from 6-8 months to 3-4 years depending on defect size and medical comorbidities↗
▶Ep 34 · 41:10
clinicalMushroom-shaped omphaloceles never reduce spontaneously and stay large↗
▶Ep 34 · 41:20
clinicalFor mushroom-shaped omphaloceles, the abdominal wall defect can be enlarged surgically as a first step to allow more spontaneous reduction before definitive repair↗
▶Ep 34 · 43:06
clinicalFormal adult-style component separation in small children carries risk of devascularization and can leave patients in worse condition if complications occur↗
▶Ep 34 · 43:35
clinicalIn omphalocele closure, the defect often extends to the costal margin, making the upper portion impossible to close primarily, requiring patch placement↗
▶Ep 34 · 44:01
clinicalSurgisis patch fails in approximately 50% of omphalocele repairs, requiring reoperation with non-absorbable mesh like Prolene↗
▶Ep 34 · 44:44
clinicalOmphaloceles can be part of pentalogy of Cantrell, commonly associated with diaphragmatic hernia of Morgagni↗
▶Ep 34 · 45:08
clinicalPentalogy of Cantrell omphaloceles tend to be more superiorly placed↗
▶Ep 34 · 45:19
clinicalMost pentalogy of Cantrell patients have cardiac problems requiring escharotic therapy for the omphalocele↗
▶Ep 34 · 45:31
clinicalIn pentalogy of Cantrell, the diaphragmatic patch can be placed from above through sternotomy during cardiac surgery, with abdominal wall repair performed later↗
