1. Neonatal Emergencies
2. “Neonatal bilious emesis is a surgical emergency until proven otherwise”
7. INCARCERATED INGUINAL HERNIA Most common in first year of life
30% of infant hernias present with incarceration most manually reducible
Dx by physical examination alone
If abdomen distended or septic obtain KUB to R/O free air
8. MECONIUM ILEUS Most commonly diagnosed at birth
1/3 of neonatal small intestinal obstructions
Occurs in 15% of infants with CF
Extremely rare in non-Caucasians
Males and females equally affected
9. MALROTATION Must consider in every infant with bilious emesis
Many subtle variations of malrotation/ nonfixation
30% present within first week of life
50% within first month
Midgut volvulus with necrosis disasterous
Can lead to SBS, intestinal tx, death
10. HIRSCHSPRUNG’S ENTEROCOLITIS Major cause of morbidity / mortality
Commonly misdiagnosed as gastroenteritis
No known etiology or effective prevention
Occurs in 1/3
Presenting sx - 7.7%; Postop - 21%
Higher incidence of enterocolitis associated with early dx, (especially first week of life): definitive repair <4 mo of age
11. Pyloric Stenosis
12. Pyloric Stenosis Most common GI obstructive anomaly in neonates
Hypertrophy of the muscular layer of the pylorus
A medical emergency but not a true surgical emergency
Incidence: 1 – 3 :1,000 live births
2 - 5x more common in first born, M > F (4:1)
13. Pyloric Stenosis Etiology : unknown
? acquired condition with hereditary
predisposition
Symptoms are apparent between 2nd-6th wk of life
Presents with nonbilious projectile vomiting, signs of dehydration, jaundice (2%)
14. Pyloric Stenosis Physical Exam
visible gastric peristalsis
palpable “olive-shaped” mass to the right
of the epigastric area
signs of dehydration
Labs: CBC serum electrolytes EKG
ABG BUN
15. Pyloric Stenosis Diagnosis
history and physical exam
abdominal ultrasound
upper GI series with barium contrast
not recommended
pathological
pyloric wall thickness = 4 mm
pyloric length of > 16 cm
16. Pyloric Stenosis
17. Pyloric StenosisPreoperative Preparation
18. Pyloric Stenosis Surgical Management
Pyloromyotomy
definitive treatment
open or laparoscopic
Lab indices for safe anesthesia
serum Cl >100 mEq/L
HCO3 < 28 mEq/L
19. Congenital Diaphragmatic Hernia
20. Congenital Diaphragmatic Hernia
21. Congenital Diaphragmatic Hernia 50% mortality regardless of the method of treatment
Incidence: 1:2,000-5,000 live births
M<F 1:1.8, frequently full term
Etiology: unknown
no genetic factors have been implicated
Antenatal history: polyhydramnios
22. Congenital Diaphragmatic Hernia
23. Congenital Diaphragmatic Hernia
25. Congenital Diaphragmatic Hernia
28. Congenital Diaphragmatic Hernia
30. Congenital Diaphragmatic HerniaIntraoperative
32. Tracheoesophageal Fistula
33. Tracheoesophageal Fistula
40. Abdominal Wall Defects
