INTRODUCTION
John Hunter is
credited with first
pathological
description of
intussusception
Early descriptions of
this condition can be
traced back to
Hippocrates.

PATHOPHYSIOLOGY



Intussusception is the most
common cause of intestinal
obstruction in infants under
2 years of age.
The median age of
presentation is 7 months
In India an increased
incidence of intussusception was reported in the
summer months
(WHO/V&B/00.23, 2000)

PATHOPHYSIOLOGY


Invagination of a bowel segment (usually small
bowel) into the lumen of the more distal bowel
(usually colon) occurs. The invaginated segment
(intussusceptum) is carried distally by peristalsis.
Mesentery and vessels become involved with
the intraluminal loop and are squeezed within
the engulfing segment (intussuscipiens). Almost
all occurrences are acute. Venous congestion is
a major factor both in symptomatology and in the
characteristic presence of blood in the stool.

AGE INCIDENCE

Aetiology
An idiopathic aetiology was reported in 42
to100% of patients in 20 studies.
 An association with a prior respiratory
infection or acute gastroenteritis was
reported in some studies.


The diagnostic difficulty in differentiating
between acute gastroenteritis or bacillary
dysentery and intussusception is present in 17% of
patients who present with rectal bleeding alone.
These patients were treated for three to five
days for bacillary dysentery before the diagnosis of
intussusception was established.
It is recommended that intussusception should be
excluded in patients with acute rectal bleeding or if
abdominal distension followed an episode of
gastroenteritis or enterocolitis.

The delay in appropriate treatment caused
by misdiagnosis contributes to the
resection rate and mortality (Jain et al.,
1990).
In another study, 52% of patients had a
preceding history of diarrhoea and had
been treated with antidiarrhoeal agents

intussusceptions are acute and
present in a well-nourished infant with
signs and symptoms of bowel obstruction
as follows:
 Cramping abdominal pain
 Poor feeding
 Vomiting

 The

infant usually has one or more
episodes of diarrhoea mixed with blood
and mucus (i.e., currant-jelly stool), which
is related to venous congestion
 A palpable, slightly tender, sausageshaped mass in the abdomen is
characteristic

 In

some patients, intussusception is
painless; the infant may appear pale,
diaphoretic, or lethargic
 The physician may not suspect
intussusception if unusual symptoms
present or if symptoms mask an upper
respiratory infection

pathological
description of
intussusception
Early descriptions of
this condition can be
traced back to
Hippocrates.

PATHOPHYSIOLOGY



Intussusception is the most
common cause of intestinal
obstruction in infants under
2 years of age.
The median age of
presentation is 7 months
In India an increased
incidence of intussusception was reported in the
summer months
(WHO/V&B/00.23, 2000)

PATHOPHYSIOLOGY


Invagination of a bowel segment (usually small
bowel) into the lumen of the more distal bowel
(usually colon) occurs. The invaginated segment
(intussusceptum) is carried distally by peristalsis.
Mesentery and vessels become involved with
the intraluminal loop and are squeezed within
the engulfing segment (intussuscipiens). Almost
all occurrences are acute. Venous congestion is
a major factor both in symptomatology and in the
characteristic presence of blood in the stool.

AGE INCIDENCE

Aetiology
An idiopathic aetiology was reported in 42
to100% of patients in 20 studies.
 An association with a prior respiratory
infection or acute gastroenteritis was
reported in some studies.


The diagnostic difficulty in differentiating
between acute gastroenteritis or bacillary
dysentery and intussusception is present in 17% of
patients who present with rectal bleeding alone.
These patients were treated for three to five
days for bacillary dysentery before the diagnosis of
intussusception was established.
It is recommended that intussusception should be
excluded in patients with acute rectal bleeding or if
abdominal distension followed an episode of
gastroenteritis or enterocolitis.

The delay in appropriate treatment caused
by misdiagnosis contributes to the
resection rate and mortality (Jain et al.,
1990).
In another study, 52% of patients had a
preceding history of diarrhoea and had
been treated with antidiarrhoeal agents
(Yadav, 1986) (WHO/V&B/00.23, 2000)

INTRODUCTION

pathological
description of
intussusception
Early descriptions of
this condition can be
traced back to
Hippocrates.

PATHOPHYSIOLOGY



Intussusception is the most
common cause of intestinal
obstruction in infants under
2 years of age.
The median age of
presentation is 7 months
In India an increased
incidence of intussusception was reported in the
summer months
(WHO/V&B/00.23, 2000)

PATHOPHYSIOLOGY


Invagination of a bowel segment (usually small
bowel) into the lumen of the more distal bowel
(usually colon) occurs. The invaginated segment
(intussusceptum) is carried distally by peristalsis.
Mesentery and vessels become involved with
the intraluminal loop and are squeezed within
the engulfing segment (intussuscipiens). Almost
all occurrences are acute. Venous congestion is
a major factor both in symptomatology and in the
characteristic presence of blood in the stool.

AGE INCIDENCE

Aetiology
An idiopathic aetiology was reported in 42
to100% of patients in 20 studies.
 An association with a prior respiratory
infection or acute gastroenteritis was
reported in some studies.


The diagnostic difficulty in differentiating
between acute gastroenteritis or bacillary
dysentery and intussusception is present in 17% of
patients who present with rectal bleeding alone.
These patients were treated for three to five
days for bacillary dysentery before the diagnosis of
intussusception was established.
It is recommended that intussusception should be
excluded in patients with acute rectal bleeding or if
abdominal distension followed an episode of
gastroenteritis or enterocolitis.

The delay in appropriate treatment caused
by misdiagnosis contributes to the
resection rate and mortality (Jain et al.,
1990).
In another study, 52% of patients had a
preceding history of diarrhoea and had
been treated with antidiarrhoeal agents
(Yadav, 1986) (WHO/V&B/00.23, 2000)

description of
intussusception
Early descriptions of
this condition can be
traced back to
Hippocrates.

PATHOPHYSIOLOGY



Intussusception is the most
common cause of intestinal
obstruction in infants under
2 years of age.
The median age of
presentation is 7 months
In India an increased
incidence of intussusception was reported in the
summer months
(WHO/V&B/00.23, 2000)

PATHOPHYSIOLOGY


Invagination of a bowel segment (usually small
bowel) into the lumen of the more distal bowel
(usually colon) occurs. The invaginated segment
(intussusceptum) is carried distally by peristalsis.
Mesentery and vessels become involved with
the intraluminal loop and are squeezed within
the engulfing segment (intussuscipiens). Almost
all occurrences are acute. Venous congestion is
a major factor both in symptomatology and in the
characteristic presence of blood in the stool.

AGE INCIDENCE

Aetiology
An idiopathic aetiology was reported in 42
to100% of patients in 20 studies.
 An association with a prior respiratory
infection or acute gastroenteritis was
reported in some studies.


The diagnostic difficulty in differentiating
between acute gastroenteritis or bacillary
dysentery and intussusception is present in 17% of
patients who present with rectal bleeding alone.
These patients were treated for three to five
days for bacillary dysentery before the diagnosis of
intussusception was established.
It is recommended that intussusception should be
excluded in patients with acute rectal bleeding or if
abdominal distension followed an episode of
gastroenteritis or enterocolitis.

The delay in appropriate treatment caused
by misdiagnosis contributes to the
resection rate and mortality (Jain et al.,
1990).
In another study, 52% of patients had a
preceding history of diarrhoea and had
been treated with antidiarrhoeal agents
(Yadav, 1986) (WHO/V&B/00.23, 2000)

Hippocrates.

PATHOPHYSIOLOGY



Intussusception is the most
common cause of intestinal
obstruction in infants under
2 years of age.
The median age of
presentation is 7 months
In India an increased
incidence of intussusception was reported in the
summer months
(WHO/V&B/00.23, 2000)

PATHOPHYSIOLOGY


Invagination of a bowel segment (usually small
bowel) into the lumen of the more distal bowel
(usually colon) occurs. The invaginated segment
(intussusceptum) is carried distally by peristalsis.
Mesentery and vessels become involved with
the intraluminal loop and are squeezed within
the engulfing segment (intussuscipiens). Almost
all occurrences are acute. Venous congestion is
a major factor both in symptomatology and in the
characteristic presence of blood in the stool.

AGE INCIDENCE

Aetiology
An idiopathic aetiology was reported in 42
to100% of patients in 20 studies.
 An association with a prior respiratory
infection or acute gastroenteritis was
reported in some studies.


The diagnostic difficulty in differentiating
between acute gastroenteritis or bacillary
dysentery and intussusception is present in 17% of
patients who present with rectal bleeding alone.
These patients were treated for three to five
days for bacillary dysentery before the diagnosis of
intussusception was established.
It is recommended that intussusception should be
excluded in patients with acute rectal bleeding or if
abdominal distension followed an episode of
gastroenteritis or enterocolitis.

The delay in appropriate treatment caused
by misdiagnosis contributes to the
resection rate and mortality (Jain et al.,
1990).
In another study, 52% of patients had a
preceding history of diarrhoea and had
been treated with antidiarrhoeal agents
