Autoimmune/allergy
Metabolic
Iatrogenic/idiopathic
Neoplastic
Social-social reason

Alcohol
Behavioural
Congenital -all
Degenerative
Drug related
Endocrine/exocrine problems
Karotype/genetic disorders

20
Q

Classification of intus

A

Idiopathic/sec
Anatomical location:
Enterocolic :ileocolic ,ileo-ileocolic
Enteroenteric :jejunojenal
Colocolic :caecolic

Single /double
Anterograde/retrograde

21
Q

Pathophysiology
Edema and swelling of the -leads to -occlusion and - occlusion
Transmural necrosis of -,peritonitis and perforation
- leads to 3rd space loss,- and -
- results in sepsis,MODS and ultimately Death

A

Intusscepien
Luminal and mesenteric vascular
Intususceptum
Fluid sequestration
transmural bacterial migration.

22
Q

Classical triad

A

Intermittent abd pain,vomiting and bloody stool

23
Q

Clinical features
Early symptoms

A

1)paroxysmal and pain
2)separated by periods of apathy
3)Vomitting

24
Q

Late symptoms

A

1)Worsening vomitting becoming bilious
2)abd distention
3)initial normal stool ,then red currant jelly stool
4)dehydration(progressive)

25
Q

Physical examination

Healthy looking child
Palpable abd mass in early presentation

Irritable,weak and lethargic
Febrile pale and dehydrated or -(in late presentation)

    Abd distention and features of peritonitis
    Rectal examination(- and -s)
A

Healthy looking child
Palpable abd mass in early presentation

Irritable,weak and lethargic
Febrile pale and dehydrated or in shock(in late presentation)

Dance sign
Abd distention and features of peritonitis
Rectal examination(blood mucoid stool,palpable mass)

26
Q

Prolapsed intus Vs rectal prolapse

A

Possiblity to freely insert index finger between anal wall and the prolapsed

27
Q

Epid
Noticed to occur more at time of weaning especially in well nourished children
Incidence is less than 30% in malnourished children
90% of cases are btw ages 3months -3yrs
There is seasonal variation

A

Noticed to occur more at time of weaning especially in well nourished children
Incidence is - in malnourished children
90% of cases are btw ages - to -
There is seasonal variation

28
Q

Definitive surgery for intussception

A

Laparotomy through right extended upper transverse incision

29
Q

Viability must be assessed before intussusceptions reduction:
If bowel is viable,-of intussusceptum from intussuscepiens for manual reduction

If viability but manual reduction difficulty cause of edema then use -around intussusceptions for 10mins then manualy reduce

If reduction impossible after above then -

If viability questionable,saline soaked and towel is wrapped and oxygen delivery is increased to -for -mons from initial -%
Then bowel is reassesed-viability achieved-manual reduction

If no viability,reaction and anastomosis is done immediately

A

If bowel is viable,milk apex of intussusceptum from intussuscepiens for manual reduction

If viability but manual reduction difficulty cause of edema then used saline soaked abd towel around intussusceptions for 10mins then manualy reduce

If reduction impossible after above -bowel resection and anastomsis

If viability questionable,saline soaked and towel is wrapped and oxygen delivery is increased to 100% for 10mins from initial 69%
Then bowel is reassesed-viability achieved-manual reduction

If no viability,reaction and anastomosis is done immediately
