Q

Ix findings bowel obstruction - AXR

A

Distended proximal bowel

Absent gas distally

17
Q

Ix findings bowel obstruction - Erect CXR

A

Fl levels in SBO

Air under diaphragm if perforation

18
Q

Why do contrast enema for bowel obstruction Ix

A

Differentiates obstruction + pseudo-obstruction

Can ID level of obstruction + ileo-caecal competency

19
Q

Mx of SBO (4)

A

A-E resus
Urinary catheter
IV ABx
Ryles tube - NBM + NG Decompression

20
Q

Mx LBO

A

Hartmans

Enema + manual evac if b/c fecal impaction

21
Q

Sx bowel strangulation (4)

A

increasing pain/tenderness
leucocytosis
Systemic upset
Peritonism

22
Q

What is volvulus

A

Twisting of loop of bowel around its mesenteric axis –> obstruction + venous occlusion at base of mesentery

23
Q

Who gets sigmoid volvulus

A

Elderly, constipated pt

24
Q

XR appearance sigmoid volvulus

A

Coffee bean appearance XR

25
Q

Tx sigmoid volvulus

A

Insertion of long flatus tube advanced into sigmoid often untwists volvulus
If unsuccessful –> laparotomy

26
Q

Who gets caecal volvulus

A

Young kids b/c = congenital malformation

27
Q

XR appearance caecal volvulus

A

Embryo

28
Q

Tx caecal volvulus

A

Untwisting via laparotomy

29
Q

SBO vs LBO - vomiting

A

Absent/faeculant in LBO

Bilious + green SBO + nausea

30
Q

SBO vs LBO - constipation

A

Absolute in LBO

May not be absolute in SBO

31
Q

SBO vs LBO - progression

A

Progression more rapid in SBO

32
Q

SBO vs LBO - pain

A

Colicky + poorly localised SBO

33
Q

PS of malrotation of bowel w/ midgut volvulus

A

Obstruction w/ PR bleed/mucus

Abnormal bowel position on AXR w/ contrast

34
Q

A 
Poor diet
Dehydration 
Lack of exercise 
IBS
Old age
Pain
35
Q
