Common clinicopathologic findings
include leukocytosis with a neutrophilia on
complete blood count.1
generally reoccur proximal to the initial
intussusception site.1,9
P
On biochemistry
panel, common anomalies include azotemia,
hyperphosphatemia, hypochloremia
and hypokalemia.1
Abdominal radiographs
may reveal a distended, gas-filled stomach
and a mass-effect within the proximal
portion of the gastrointestinal tract,
often within the pylorus or fundus for
patients with pylorogastric intussusceptions.1,5
Abdominal
ultrasound, which is
highly sensitive and specific for the diagnosis
of intussusceptions, may reveal multiple
concentric rings on transverse imaging or
parallel lines on longitudinal views.1,4-5
Surgery
is necessary for immediate correction
and to prevent recurrence.
Manual reduction of the intussusception
can be attempted after careful inspection
of tissue viability and patency of
enteric vessels.1 Resection and anastomosis
or gastrectomy may be required if
tissues are compromised, lesion is unreducible,
or neoplasia is suspected.1,4-5
Following
reduction, enteroplication can be
performed to reduce risk of recurrence,
although the procedure does not reduce
the potential for complications postoperatively
or mortality.1,4-5

pyloric antrum (white arrow) is intussuscepted
into the fundus (black arrow) of the stomach. The
serosal surface of the stomach appears reddened
and grossly thickened.
flap advancement pyloroplasty has been
described in a very limited number of
cases with gastric outflow disease to aid in
widening the pylorus.1,3-5
The long-term
follow-up and risk of recurrence for this
technique is not well described. Information
regarding prognosis is fairly limited
in the literature for retrograde intussusceptions
with some studies reporting a
guarded prognosis.1
intussusceptions vary between 3-25% and
