8. Key Terms
Fistula: It is an abnormal communication between two epithelial-
lined surfaces.
Atresia: It refers to complete obliteration or absence of an orifice
of a hollow organ.
Stenosis: It is a change in diameter of a hollow organ to become
narrower.
10. Overview
Tracheoesophageal fistula (TEF) is an abnormal communication
between Esophagus and Trachea.
Esophageal atresia (EA) is when the esophagus ends blindly and is not
in continuity with the stomach.
It often occurs with EA & these are the most common congenital
anomalies of esophagus and trachea.
Early diagnosis is important to minimize complications.
Tracheoesophageal Fistula
11. Classification
According to the system formulated by Gross:
Type A – Esophageal atresia without fistula or pure esophageal atresia (10 %)
Type B – Esophageal atresia with proximal TEF (˂ 1%)
Type C – Esophageal atresia with distal TEF (85%)
Type D – Esophageal atresia with proximal & distal TEFs (˂1%)
Type E – TEF without esophageal atresia or H-type fistula (4%)
Type F – Congenital esophageal stenosis (˂1%)
Tracheoesophageal Fistula
13. Frothing and bubbling at mouth.
Episodes of cough and cyanosis.
Respiratory Distress
Regurgitation.
Episodes of coughing and choking associated to cyanosis.
Tracheoesophageal Fistula
Clinical Features
14. Diagnosis
EA or TEF may be suspected prenatally if
ultrasound examination reveals polyhydraminos or
absence of stomach gas.
TEF may be detected postnatally by chest x-ray
which will reveal a coiled feeding tube in
esophageal pouch and/or air distended stomach.
Inability to pass NG tube.
Tracheoesophageal Fistula
15. Treatment
Supportive:
Antibiotic
Prone position and suction
Prevent endotracheal intubation to prevent abdomen distention.
Specific:
Surgical ligation of TEF and primary end-to-end anastomosis of esophagus via right sided thoracotomy.
Primary repair is delayed in pts with LBW, complications or anomalies, initially treat pts conservatively
with parenteral nutrition, gastrostomy until they are considered at low risk.
In healthy infants primary repair is performed within first few days of life.
Complication:
Anastomotic leak.
Refistulization and anastomotic stricture.
Tracheomalacia.
Tracheoesophageal Fistula
17. Overview
Duodenal atresia is most common site of neonatal
intestinal obstruction.
It is congenital absence or complete closure of
portion of lumen of duodenum, result from failed
recanalization of intestinal lumen during
gestation.
50% of infant with duodenal atresia are
premature.
25 – 40 % are associated with down syndrome.
Duodenal Atresia
18. Bilious vomiting without abdominal distention mostly on 1 DOL.
Peristaltic waves may be visualized early in disease.
1/3rd of cases may develop jaundice.
Absence of flatus.
Duodenal Atresia
Clinical Features
19. Diagnosis
On plain abdomen radiography double
bubble sign.
U/s abdomen pyloric thickness 3-4 mm and
pyloric length 15-19 mm is diagnostic.
Duodenal Atresia
20. Treatment
Insertion of NG or orogastric tube for decompression.
IV fluids for rehydration.
Surgical repair of duodenal atresia is Duodenoduodenostomy.
Post-operatively gastrostomy tube can be placed to drain
stomach and protect airway.
Trans anastomotic jejunal tube is needed until infant start oral
feed.
Duodenal Atresia
22. Overview
It is most common congenital anomaly of GIT caused by incomplete
obliteration of omphalomesenteric duct during 7th week of gestation.
It is an outpouching or bulge in lower part of small intestine.
Referred to by the rule of 2’s
2% of the population
Usually found 2 feet proximal to the ileocecal valve.
About 2 inches long.
2 times more common in males than females.
Symptomatic mostly before 2 years of age.
Meckel’s Diverticulum
23. Mostly asymptomatic.
Symptoms typically appear in first or second year of life.
Intermittent painless rectal bleeding.
Stool are typically brick color or currant jelly color.
Anemia
Meckel’s Diverticulum
Clinical Features
24. Diagnosis
Usually clinical (It account for 50% of all GUT bleeding in child
younger than 2 years).
Technetium pertechnetate scan/Meckel scan which is dependent on
uptake of isotipe in heterotopic tissue.
Management is by surgical excision of diverticulum by
divertuculectomy.
Meckel’s Diverticulum
26. In Neonates and Infants
Failure to pass meconium
Abdominal distension
Bile-stained vomiting
Episodes of diarrhea & constipation
In Older Children
Constipation with abdominal distension
When stool passed foul smelling, and liquid in consistency
Malnourished and anemic
Hirschsprung’s Disease
It is a developmental disorder characterize by absence of ganglionic cells in
sub mucosa and myenteric plexus.
27. Pathophysiology
Due to absence of ganglionic cells
Lack of peristalsis in the affected portion
Functional obstruction of colon
Accumulation of gas & feces proximal to
the defect
Enlargement of the colon occurs and
called Megacolon.
Hirschsprung’s Disease
28. Diagnosis
Suspected in a baby who has not passed
meconium within 48 hrs. of birth
Rectal suction biopsy
Palpation
Anorectal manometry
Contrast enema
Hirschsprung’s Disease
29. Medical Treatment
Laxatives
High fiber diet
Increased fluid
Surgical Treatment
Previously temporary ostomy was placed and definitive surgery was delayed until
child was older, currently many infants undergo primary pull-through procedures:
1. Swenson was to excise the aganglionic segment and anastomose the normal proximal
bowel to rectum 1-2 cm above the dentate line.
2. Duhamel procedure to create neorectum bringing down normally innervated bowel
behind the ganglionic rectum.
3. Soave involve stripping the mucosa from aganglionic rectum and bringing normally
innervated colon through residual muscular cuff thus bypassing abnormal bowel from
within.
Hirschsprung’s Disease
31. Overview
It is most common acute surgical emergency in children.
An acute inflammation of appendix causes acute severe abdomen pain.
Predisposing factors
Facolith Obstruction
Family history
Lymphoid hyperplasia
Tumor
Appendicitis
32. Local tenderness is elicited at McBurney's point when pressure is applied
Rebound tenderness (i.e., production or intensification of pain when pressure is released)
may be present
Symptoms
Abdominal pain > 95%
Anorexia > 70%
Constipation: 4-16%
Diarrhea: 4-16%
Fever: 10-20%
Migration of pain to right lower quadrant: 50 – 60 %
Nausea Vomiting > 65 %
Appendicitis
Clinical Features
33. Score Significance
1 – 4 Unlikely to be acute appendicitis
5 - 6 Possible diagnosis of acute appendicitis
7 – 8 Acute appendicitis present
9 – 10 Definite acute appendicitis requiring surgery
Appendicitis: Clinical Evaluation
34. Diagnosis
Based on history and clinical examination
CBC
CRP
Ultrasound studies
CT
Appendicitis
37. Overview
Most common surgically treatable cause of cholestasis in newborns.
It is a condition in which extra hepatic biliary system is disturbed.
Progressive damage of extra hepatic and intrahepatic bile ducts secondary
to inflammation may occur.
Infants with prolonged jaundice should be thoroughly investigated for BA.
BA should be considered in all neonate with direct hyperbilirubenmia.
About 30% of cases extra hepatic biliary atresia associated to Polysplenia
syndrome which is characterized by situsenversus, interruption of IVC,
Malrotation levocardia and heterotaxia.
Biliary Atresia
38. Jaundice in newborn period but may be delayed until 2-3 weeks.
Deep yellow urine
Light stools/acholic stools
Hepatomegaly
Splenomegaly may develop
Biliary Atresia
Clinical Features
39. Diagnosis
HIDA scan distinguish intrahepatic from extrahepatic causes
of cholestasis.
Elevation of serum Gamma-glutamyltranspeptidase or
Alkaline phosphatase.
Prolong prothrombin time
U/s abdomen: Gall bladder is not visualized, Exclude specific anomalies of
extrahepatic biliary system particularly choledochal cyst.
Liver Biopsy: Ductal proliferation with bile plugs and fibrosis while basic
liver lobules are intact.
Biliary Atresia
40. Treatment
Supportive
Vitamin A,D,E and K.
Antibiotics
Surgical
Hepatoportoenterostomy (Kasai procedure)
Portocholecystomy (Gall bladder Kasai procedure)
Ideal age is 6-10 weeks
Ultimate cure is liver transplant in those who fail to drain bile after kasai
procedure.
