Abstract Primary care physicians are often required to
initially manage the children with surgical emergencies. Many
neonates with congenital malformations delivered without
supervision may also be managed initially by the family
physicians. The role of the primary care physician in such
cases should be to diagnose the condition correctly, provide
immediate care and then refer the newborn or child to higher
centre for appropriate management.

Spinal Dysraphism and Hydrocephalus
Spinal dysraphism or neural tube effects are a major cause of
morbidity and mortality, and have long term consequences on
quality of life of the patients as well as the care givers. These
defects occur due to abnormal neurulation during fetal
development. The defect can occur from head to the sacral
region. Cranial lesions may include a) anencephaly; b)
encephalocele (Fig. 1), or c) cranioschisis. Amongst the many
types described, common varieties of spinal lesions include a)
meningomyelocele; b) meningocele; c) rachischisis (Fig. 2) d)
lipomeningomyelocele; and; e) congenital dermal sinus [1]. Most
common type seen in clinical practice is meningomyelocele as
many severe types result in perinatal mortality.
Most lesions can be diagnosed on antenatal ultrasound and
appropriate management should be advised to the parents after
counseling about the prognosis of the lesion. Severe
anomalies are associated with intrauterine death. If seen for
the first time after birth, diagnosis can be made on clinical
examination. The lesion can appear as a cystic lesion, or open
defect with leak of cerebrospinal fluid. Spina bifida occulta
may present as skin covered lesion, a sinus, or tuft of hair on
the back. Special attention is required to look for neurological
sequelae like paresis, fecal and urinary incontinence, and
associated hydrocephalus. Head circumference should be
measured and monitored for evidence of hydrocephalus.
Required investigations include ultrasonography and
magnetic resonance imaging [2].
After proper neurological assessment and explaining the
prognosis, surgical repair of the lesion can be performed in most
cases. It must be explained to the parents that the neurological
deficit and hydrocephalus may not improve after surgery but
may become apparent or worsen in postoperative period.
Hydrocephalus may require insertion of ventriculoperitoneal
shunt before or after correction of spinal defect. The parents
must be counseled that the condition may occur again in the next
sibling but incidence can be reduced by administration of folic
acid before conception.

This is one of the common but most severe anomaly of
the upper gastrointestinal tract. This occurs due to a
developmental defect in the foregut. In the most common
type, the upper end of esophagus is blind while the lower
esophagus communicates with the trachea or bronchus
leading to trachea-esophageal fistula. The anomaly is

and frothing at mouth. The child may have rapid respiratory
rate due to aspiration pneumonia. X-ray after insertion of a
nasogastric feeding tube will show coiling of the tube in the
neck. Such a child requires immediate suction of all the
contents in the oral cavity and throat; stopping of all the feeds,
initiation of intravenous fluids and oxygen, and transfer to a
tertiary care centre under supervision where surgery can be
performed by the pediatric surgeons [4].

associated with many other congenital anomalies described by
the acronym VACTERL (Vertebral, Anal, Cardiac, TracheoEsophageal, Renal/Renal and Limb defects). Therefore, in a
child suspected or diagnosed to have esophageal atresia, it is
important to perform clinical examination and investigations
to rule out other associated anomalies [3].
If delivered in the hospital setting, the diagnosis is usually
made in the immediate postnatal period. But in case of
unsupervised delivery, the diagnosis may be missed and the
baby generally presents with failure to accept feeds, cyanosis,
Apart from pneumonia and other medical causes, surgical
causes of respiratory distress in a newborn include congenital
diaphragmatic hernia, trachea-esophageal fistula,
pneumothorax, and congenital lung malformations like
congenital cystic adenomatoid malformation and congenital
lobar emphysema. The child presents with signs of respiratory
distress like tachypnea, cyanosis, chest retractions etc. [5].
In case of congenital diaphragmatic hernia, the abdomen
appears scaphoid in shape. The apex beat may be shifted to
opposite side and one can appreciate bowel sounds in the
thorax on the side of hernia [6]. If a case of suspected
congenital diaphragmatic hernia requires resuscitation, it is
advised to intubate the trachea and ventilate in preference to
bag and mask ventilation because the later may worsen the
respiratory distress.
The x-ray findings are quite suggestive of individual
lesions. In diaphragmatic hernia, bowel may be seen in the
chest, heart is shifted to opposite side and bowel shadows in
the abdomen are decreased. The x-ray in congenital lobar
emphysema may mimick pneumothorax. This sometimes
results in insertion of intercostal tube drainage without any
clinical improvement. In both conditions, it is recommended
that the primary care physician should initiate the child on
intravenous fluids and oxygen, and transfer the baby to a
higher centre for management. Contrary to previous belief of
immediate surgery, it is necessary to resuscitate and stabilize
the hemodynamic status of the neonate before repairing the
diaphragmatic defect [6].
Idiopathic Hypertrophic Pyloric Stenosis
Fig. 2 Rachischisis
Idiopathic hypertrophic pyloric stenosis is a condition wherein
functional gastric outlet obstruction occurs secondary to
hypertrophy and hyperplasia of the muscular layers of the
pylorus. The condition is more common in males and first
born babies. The incidence is about 2–4/1000 in western
countries and is less common in India. They usually present
with progressive, non-bilious, projectile vomiting in the first
month of the life. Untreated, the child may develop
hematemesis and a small percentage may develop jaundice.

Clinical examination reveals a malnourished child with
varying degree of dehydration. Due to continued vomiting
of gastric contents, there is hypokalemic, hypochloremic,
metabolic alkalosis. Urine output is reduced. Abdominal
examination shows visible peristalsis moving from left to
right, and the pyloric mass may be felt in 3/4th of the cases.
For this, an empty stomach child is put to the left breast of the
mother, and an attempt is made to feel the mass in the right
hypochondrium on deep palpation using left hand as the child
is feeding. Ultrasound examination confirms the diagnosis in
most cases and contrast studies are usually not required.
It is important to adequately resuscitate the infant and
correct the electrolyte imbalance before contemplating
surgery [7]. Pyloromyotomy remains the standard treatment
of choice and can be performed laparoscopically.
Intestinal Obstruction
Intestinal or bowel obstruction is one of the most common
emergencies seen by the primary care physician. The causes
of intestinal obstruction are different in neonates and older
children but the principles of management remain the same.
Intestinal obstruction in the neonates is usually due to
congenital anomalies and includes Hirschsprung’s disease,
duodenal and intestinal atresia, malroation and volvulus,
meconium ileus etc. Common causes of intestinal obstruction
in infants and older children include Hirschsprung’s disease,
congenital bands and malrotation, intussusceptions (Fig. 3),
obstructed internal and external hernia. Tuberculosis and
ascariasis (Fig. 4) still remain common causes of intestinal
obstruction in India [8]. Detailed description of individual
conditions is beyond the scope of this review.
Acute intestinal obstruction may present with bilious
projectile vomiting, pain, distension of abdomen and failure
to pass stools and may vary with the condition. A neonate who
presents with projectile bilious vomiting with or without
blood, abdominal distension and features of shock should be
considered to have malrotation with volvulus and managed
accordingly. It cannot be overemphasized that bilious
projectile vomiting is a definite sign of acute intestinal
obstruction. Occasionally, paralytic ileus associated with other
conditions like sepsis, pneumonia, and some drugs may
mimick dynamic intestinal obstruction but should be managed
conservatively. Plain x-ray in erect position demonstrates
multiple air-fluid levels and may show gas under the dome
of diaphragm if there is an intestinal perforation.
Any child suspected to have acute intestinal obstruction
should be kept nil orally; nasogastric tube should be inserted
to aspirate the intestinal contents; and the child should be put
on appropriate intravenous fluids. A severely dehydrated child
is catheterized to monitor urinary output. The child is then
transferred to a facility for the appropriate surgical procedure

individual condition.
Abdominal Wall Defects: Omphalocele and Gastroschisis
Omphalocele and gastroschisis are congenital abdominal wall
defects which present in neonatal period and require

closure and gradual reduction followed by closure of

cases.
immediate surgical intervention. Omphalocele is a defect in
which the abdominal contents fail to return to abdominal
cavity during fetal development. The contents commonly
include intestine and liver which are covered by a
membranous sac (Fig. 5a). In gastroschisis, on the other side,
intestines protrude through a defect to the right of umbilicus
and are usually edematous, thickened (Fig. 5b) and may be
atretic [9] . If diagnosed on antenatal ultrasound, the parents
should be advised to have the delivery at a health care facility
where surgery can be performed for these defects.
Initial management of both the conditions includes
covering of the lesions and the contents with a moist sterile
dressing or a sterile bag; nasogastric tube to decompress the
intestinal tract; maintenance of temperature and asepsis; and
intravenous fluids to adequately hydrate the neonate. The
child with gastroschisis is nursed in lateral position during
stay in the hospital and transfered to a centre with facility for
neonatal surgery. The treatment includes reduction of the
contents in to the abdominal cavity and closure. It is usually
possible to close the defects primarily in small omphalocele
and most gastroschisis; it may not be feasible to perform
primary closure in some cases. In such cases, alternatives
include skin closure and creation of a ventral hernia or silo
Anorectal malformations occur with an incidence of about 1 in
5000 and are one of the most common congenital anomalies
seen by pediatric surgeons. These include a wide spectrum of
conditions in both males and females. Most cases present in
the neonatal period, however some girls may present in later
life with missed or untreated defects.
While the most commonly used Wingspread classification
divided the anomalies into low, intermediate and high
anomalies, the recent Krickenbeck’s classification divides
them as major clinical groups and rare regional variants. In
males, there is generally complete absence of an anal opening
(Fig. 6a) and the child may pass meconium with urine in case
of a rectourinary communication. In the girls, there is usually a
perineal fistula through which she may pass meconium and
decompress (Fig. 6b). It is important to rule out other

associated anomalies in a child with anorectal malformation.
Anomalies like covered anus, anterior perineal anus,
anocutaneous fistula, anovestibular fistula, and anal stenosis
can be managed by a primary perineal procedure as a
definitive treatment in neonatal age [11]. However, most other
conditions require colostomy at birth and divided sigmoid
colostomy is the preferred procedure. The child is subjected
to radiological investigations like distal colostogram to define
the anatomy, micturating cystogram to rule out reflux,
ultrasound to rule out renal anomalies and echocardiogram
to check for cardiac anomalies. While the low anomalies are
managed by perineal anoplasty, posterior sagittal
anorectoplasy is the most preferred surgical procedure for
other common anomalies. It is important for primary care
physician to not explore the local anal site as it may disturb
the anatomy and inadvertently damage the sphincter system,
and affect the results of definitive repair.
Paraphimosis
Paraphimosis is a condition wherein the prepuce cannot be
pulled back over the glans after it has been retracted back. It
generally results due to forcible retraction of the tight prepuce
by the clinician or the parents for performing any procedure or
cleaning. The retracted prepuce become swollen and
edematous and cannot be brought back over the glans in the
original position. The condition is quite painful and may be
associated with retention of urine.
The condition is best avoided by small precautions. A tight
prepuce should not be retracted back forcibly with a mistaken
diagnosis of phimosis. If retracted, it should be pulled back
over the glans after cleaning or the procedure [12].
Paraphimosis can be treated by manual compression of the
swollen foreskin followed by reduction of prepuce over the
glans. In some cases, needle puncture may be done to express
the edema fluid. An emergency dorsal slit or circumcision
should be the last option for the management of paraphimosis.
The child requires analgesics and antibiotics in some cases.
Testicular Torsion
Torsion of the testis is a surgical emergency where the
spermatic cord twists and results in ischemic damage to the
testis [13]. The event may occur even in antenatal period
resulting in an atrophic or vanishing testis. In the pediatric
age, torsion occurs more commonly in the prepubertal age.
The condition presents as severe scrotal pain of acute onset,
along with swelling and erythema of the scrotum. It is usually
associated with nausea and vomiting. Examination reveals a
high tender testis with an abnormal orientation. Opposite testis
may also be abnormally positioned.
795
Clinical examination is most important in making a diagnosis
of torsion of testis. Epididymoorchitis and some other testicular
inflammatory conditions may mimick torsion. Torsion can be
confirmed on Doppler ultrasound and nuclear scan. However,
this is one emergency where surgical intervention may be
required even with a doubtful diagnosis. Delay should not be
done for the want of diagnostic investigations as this leads to
loss of viability of testis. Scrotal exploration is done to untwist
the cord, confirm the viability of the testis and orchiopexy.
Orchidectomy is necessary for non-viable testis. Most surgeons
fix the opposite testis at the same time.
Take Home Message
It is important to note that primary care physicians are often
the first medical contacts for children with surgical
emergencies and play a role in improving outcome of these
cases [14]. Most conditions may be beyond their expertise but
prompt diagnosis, optimal initial management and timely
referral to a centre with facility for neonatal and pediatric
surgery are necessary. One should ensure appropriate
temperature maintenance, proper hygiene and cleanliness,
insert nasogastic tube wherever appropriate, administer
intravenous fluids, and start broad spectrum antibiotics
wherever deemed necessary. The transfer of the child should
be done with possible prior information to the centre so that
preparations can be done for prompt management.
