Introduction
limentary tract duplications, a group of rare
malformations, vary greatly in appearance, size,
location and symptoms. Duplications of ileum appear as
noncommunicating spherical cysts. They are mistaken
for mesenteric or omental cysts because of their location
but are clarified by identification of mucosa rather than
endothelial lining [1].
Case Report
A 53 days old male infant presented with vomiting and
abdominal distension of 5 days duration. The vomiting was
bilious and associated with progressive abdominal
distension. The child had not passed stool. Antenatal and
perinatal period was uneventful and infant was exclusively
breast fed. Clinically the infant had moderate dehydration
and visible distended bowel loops. On palpation a firm cystic
mass was felt in right lumbar region, bowel sounds were
exaggerated, external genitalia and hernial sites were normal.
Abdominal radiograph revealed soft tissue density lesion
in right lumbar region deviating bowel loops to the left side
(Fig 1). Ultrasonography revealed a cystic mass in right lumbar
region. Abdominal CT revealed a well defined round
uniloculated cystic lesion in the Right lumbar region
67x52x60mm in size suggestive of intestinal duplication cyst
with a grossly distended stomach (Fig 2). There was no
malformation of the vertebral column or genitourinary tract.
The neonate was taken up for exploratory laparotomy
through supraumbilical transverse incision. The laparotomy
revealed 7"x6"x5" size intestinal duplication cyst about 18"
from the duodenojejunal flexure. The proximal bowel was
grossly distended and distal loop collapsed. Resection and
anastamosis of jejunum containing the duplication cyst was
done. Postoperatively infant was managed with antibiotics,
intravenous fluids and analgesics. On the 6th postoperative
day infant passed flatus, by 8th postoperative day was breast
fed and was discharged on 14th postoperative day. Gross
examination of excised specimen revealed a (Fig 3), small
nodular cystic mass 7cm diameter, attached to intestine with
straw coloured mucoid content. Section from cyst wall shows
a flattened epithelium and at places low cuboidal epithelial
*
wall containing fibrous tissue and ecstatic congested blood

vessels.
Discussion
Duplication of the intestinal tract are rare anomalies
consisting of well formed tubular or spherical structures
firmly attached to the intestine on the mesenteric side
of the lumen. Lined with intestinal mucosa they share a
common wall and mesenteric blood supply with the
adjacent intestine but usually not communicate with the
gut lumen. Potter reported 2 cases in more than 9000
foetal and neonatal autopsies [1].

The duplication can be classified into localized

duplication, duplication associated with spinal cord and
vertebral malformation and duplication of the colon.
Localized duplications are common in the ileum and
jejunum [2]. Theories explain duplication as a defect in
recanalisation of the intestinal lumen after the solid stage
of embryological development. The split notochord
theory proposes neural tube traction mechanism resulting
in intestinal duplication along with vertebral and spinal
cord anomalies (hemivertebrae, anterior spinabifida,
band connection between lesion and cervical or thoracic
spine) [1,2].
The symptoms depend on the size, location and
mucosal lining of the cyst. Patient may present with
abdominal pain, vomiting, palpable mass or acute
gastrointestinal haemorrhage. Intestinal duplication in
thorax may present with respiratory distress. Due to
nonspecificity, a preoperative diagnosis based on
radiography is unlikely. Upper GI study and barium
enema demonstrate filling defect or rarely a
communication between the cyst and normal bowel [3].

The ultrasound and CT Scan are useful in establishing
diagnosis and may be used to evaluate synchronous
lesion once a single duplication has been identified [1].
Duplication of cyst manifest as smooth, rounded, fluid
filled cysts or tubular structure with thin slightly enhancing
wall on CT Scan. MRI scan shows intracystic fluid with
heterogenous signal density on TI weighted image and
homogenous high signal intensity on T2 weighted
image [4].
Treatment of small cystic or short tubular duplication
involves segmental resection along with adjacent
intestine. A long tubular duplication cannot be excised
as it will lead to short bowel syndrome. In these cases
mucosal stripping through a series of multiple incisions
is recommended [5].
