Q

what is a normal barium swallow procedure

A

-Fluoroscopy is used initially to visualise swallowing mechanisms functionality and to make sure on initial swallow there is no aspiration.

A small amount of barium (a sip) is taken at this stage: held in the mouth until given the ok to swallow

Once safety has been established, a full cup of barium is given to the patient

The patient is standing upright or seated, in the fluoroscopic machine

Q

contraindications of buscopan (8)

A
  1. fructose intolerance
  2. myasthenia gravis
  3. glaucoma
  4. mega colon
  5. heart arythmia
  6. bowel/stumoch onstruction
  7. warfarin or heparin
  8. passed its use by date
17
Q

how can buscopan cause problems

A
  • it can affect other muscle groups besides the colon
  • If eye muscles don’t work or are slowed down then pressure builds up in the eye.
  • Glaucoma is when the optic nerve is slowly compromised. if Buscopan causes increased eye pressure, it can accelerate the underlying condition of Glaucoma.
18
Q

imaging techniques for barium meal

A

Control image

Double contrast

Single contrast: barium only

Supine or erect

RAO: duodenal cap

Erect LPO and lateral: different views of duodenal cap

Prone shows the mid portion of the duodenum

Supine RPO shows the lower 2/3s of the duodenum

19
Q

post care for barium meal

A

Bowel motions may be a “lighter” colour for up to 72 hours after the procedure

“pushing” to have a bowel motion too
hard may cause internal bleeding

Eat healthy foods like grains, vegetables to aid in bowel motion

Drink plenty of water for the next 24hrs after the procedure

Drinking dehydrating substances (eg alcohol, coffee, caffeine drinks etc) may cause the Barium to “set” or harden causing constipation

Prune juice will help in improving the motility of the bowel

20
Q

complications of barium meal

A

Usually arise from lack of after care.

the patient will usually have a bowel blockage, react to the barium in some way.

21
Q

barium meal and follow through vs. small bowel series

A

Barium meal and follow through: mouth to larynx plus the duodenum as well as the Oesophagus and small bowel

Small bowel series: only examines the small bowel

22
Q

barium prep for barium meal and follow through and small bowel series

A

Larger dose of Barium is given so that ALL of the small bowel can be seen.

The examination can take up to 8 hours. To aid in the flow of Barium, the patient can walk around the department, drink a little water to help flush things through

23
Q

barium meal and follow through and SBS prep

A
  • check pregnancy
  • check if patient has had other barium studies/biliary studies
  • night before: pt doesn’t eat anything
  • NBM or only clear fluids
  • change into hospital gown, remove metal items from upper GIT
24
Q

barium meal and follow through and SBS indications

A
  1. Strictures
  2. Mass
  3. Abnormal motility of the small bowel
  4. Bloating
  5. Generalised pain
  6. Excessive Nausea
  7. Non synchronized contractions of the small bowel
  8. Diarrhoea
  9. Constipation
  10. Gastroparesis
25
Q

imaging for barium meal and follow through

A

Control image

Double contrast

Single contrast: barium only

Supine or erect

RAO: duodenal cap

Erect LPO and lateral: different views of duodenal cap

Prone shows the mid portion of the duodenum

Supine RPO shows the lower 2/3s of the duodenum

26
Q

imaging for SBS

A
  • Immediate AXR
  • 15 minute AXR
  • 30 minute AXR

Some images may be done Prone to “spread out” the small bowel. Sometimes sponges are used to put pressure on various parts of the small bowel.

The aim of the sequence of images is to demonstrate ALL of the small bowel.

Imaging ends when the Ileocecal junction is reached.

27
Q

post care for barium meal and follow through and SBS

A

Bowel motions may be a “lighter” colour for up to 72 hours after the procedure

“pushing” to have a bowel motion too
hard may cause internal bleeding

Eat healthy foods like grains, vegetables to aid in bowel motion

Drink plenty of water for the next 24hrs after the procedure

Drinking dehydrating substances (eg alcohol, coffee, caffeine drinks etc) may cause the Barium to “set” or harden causing constipation

Prune juice will help in improving the motility of the bowel

28
Q

complications of barium meal and follow through and SBS

A

bowel blockage

29
Q

gastrografin use in SBS indications

A
  1. Suspected Bowel perforation
  2. Peptic ulcer causing perforation
  3. Resection of bowel (post-operative)
  4. Complete obstruction in bowel
  5. Post-operative ileus (decreased motility)
  6. Acute haemorrhage
  7. Pre-operative investigation
  8. Megacolon
  9. Fistula
30
Q

preparation for gastrografin SBS

A

check pregnancy

  • check if patient has had other barium studies/biliary studies
  • night before: pt doesn’t eat anything
  • NBM or only clear fluids
  • change into hospital gown, remove metal items from upper GIT
31
Q

contraindications for gastrografin SBS

A
  1. Suspected Aspiration
  2. Broncho Fistula
  3. Allergy/sensitivity to Gastrografin or Iodine
  4. Pregnancy
  5. Same contraindications as for Iodine studies
32
Q

barium enema antomy covered

A

large bowel only

33
Q

barium enema bag prep

A
  1. Clamp the end of the tub
  2. Pour the Barium into the bag
  3. Before tipping the bag up, fill the bag with air
  4. Once the bag is full of air and Barium tip the bag up so that the barium runs to the bottom of the tube
  5. Hang the bag up on an IV pole
  6. Have tape ready so the tube can be secured.
  7. For single contrast Barium study you do not need to blow the bag up with air

  4. Megacolon
  5. Acute abdominal pain
  6. Rectal pathology that could be perforated on inserting the tube
36
Q

imaging sequence for barium enema

A
  • Pre Contrast AXR(s).
  • KV setting should be around 90kv
  • The patient may be required to roll 360 degrees to coat the inner lining of the bowel
  • Supine projection: general anatomical view
  • Prone projection: to move the area to the ascending and descending colon
  • RAO to include rectum
  • LPO for Hepatic Flexure
  • RPO for Splenic Flexure
  • Supine Caudal (20 degrees) over rectum area
  • L and R decubitus to see filling of Ascending and Descending Colon
  • Lateral (patient prone) Rectal X-ray
37
Q

after care for barium enema

A
  • The tube is withdrawn, and the patient is asked to void in the toilet
  • Let the patient know that the stool will be white colour for up to 72 hours
  • Bloating can occur and flatulence is a normal affect, and not to hold it in as it can cause an obstruction
  • Patient should drink water, LOTS of water
  • Patient should avoid dehydrating substances
38
