21. Intestinal obstruction

22. Definition:
• Intestinal Obstruction(IO) is a condition in
which there is a sudden stoppage of the
onward passage of intestinal contents-i.e. Gas,
digestive juices and food

23. Intestine

24. CLASSIFICATION
According to:
Aetiopathology
Onset
Level
Nature

25. Peristalsis is working against
a mechanical obstruction
DYNAMIC
(MECHANICAL)
Result from atony of the
intestine with loss of normal
peristalsis, in the absence of a
mechanical cause.
or it may be present in a non-
propulsive form (e.g. mesenteric
vascular occlusion or pseudo-
obstruction)
ADYNAMIC
(FUNCTIONAL)

26. Small or Large bowel
High (Proximal) or Low (Distal) small bowel


According to LEVEL

27. High IO- near the ampulla- jejunum and
proximal ileum.
Low IO- distal to the ampulla- distal ileum
and colon.

29. According to nature of Obstruction:
1.Simple Obstruction- the bowel lumen is occluded ,blood supply remains
intact. The source of obstruction is usually intra-abdominal. ( Eg. Intra-
abdominal adhesions, very rarely gallstones, ball of worms, bezoars).
2. Strangulation- the bowel lumen together with its blood supply is cut-off.
Eg. Strangulated inguinal hernias. Pure strangulation without bowel
luminal narrowing is usually due to mesenteric embolism/thrombosis.

30. 3. Closed loop obstruction- The bowel is
obstructed both proximally and distally. Here
the blood supply may be impaired.
A classic example is seen in an obstruction of
the colon with a competent ileo-caecal valve.
NB: All the 3 types spoken about can occur at
the same time for example in a strangulated
inguinal hernia.

31. Closed loop obstruction

32. According to onset:
-Chronic Obstruction-Usually seen in large
bowel obstruction. The symptoms may arise
from the cause and the subsequent obstruction.
-Acute on Chronic Obstruction- sudden
obstruction in a previously incomplete
obstruction.
Sub-acute Obstruction- There is a partial
obstruction.

33. Causes Dynamic obstructrion

34. BANDS

35. Ball of Ascaris worms

36. Adynamic cause of Obstruction
•Paralytic ileus
•Electrolyte imbalance
•Spinal injury
•Diabetis mellitus
•Renal surgeries
•Mesenteric ischemia

37. Pathophysiology

38. Clinical presentation
The clinical presentation varies according to;
-The location of the obstruction
-The age of the obstruction
-Underlying pathology
-Presence or absence of intestinal ischaemia.

39. Clinical features
•Abdominal pain
•Vomiting
•Distension
•Constipation
•Dehydration
•Feature of toxemia and septicemia
•Feature of strangulation
•Temperature
•Bowel sound
•Per rectal examination

40. Small vs large bowel obstruction

41. Investigation
•CBC
•Electrolyte Na/K
•Plan X-ray abdomen erect and supine
•CT scan

42. A.Investigations
(i) Supportive- FBC, BU+Cr. Other investigations may be
requested on the basis of clinical suspicion.
(ii)Diagnostic
-Plain abdominal x-rays
Erect and supine
-CXR
-Enema
-Endoscopic techniques

43. Managmenet
I.V fluids and electrolytes rescusitation
N.G tube if repeated vomiting
Antibiotics
Exploratory laparatomy
Hernia  operation
Adhesions  Adhesiolysis
Obstruction  remove
Volvulus  derotate and or operate
Mesenteric ischemia  operate
Abscess or peritonitis  drain and treat
Intussusception  pneumatic or barium reduction or operate
