6
Q
2 Methods of SBFT
A
Mouth
- in combination with UGI
- oral
Enteroclysis
- direct injection of contrast into an intestinal tube
- small intestine enema
7
Q
Contraindications of SBFT
A
- complete obstruction
- suspected perforation
- pre surgical patients
- concern for fecal impaction
8
Q
Equipment needed for SBFT
A
- barium
- fluorscope
- spot image device
- over table tube
- video recording system
- time markers on all images
9
Q
Prep for UGI and SBFT
A
- low residue diet 2-3 days prior to exam
- NPO 8-12 hours prior to exam
- no smoking or chewing gum
- remove all clothing, gown
- possible cleansing enema before
10
Q
w/v% for SBFT
A
-30-50% (1-2 cups)
- possible negative contrast CO2 fizzy tablets
11
Q
Procedure for Upper GI or SBFT
A
- preliminary scout image
- notation of time 1st cup of barium is ingested
- Fluoroscopist will perform upper GI first
- second cup of barium is ingested
- first image taken immediately following ingested - PA/AP (centered at L2)
- 30 minute image - PA/AP centered at L2
12
Q
Oral Method of SBFT
A
- after 30 min image every half hour centered at iliac crest
- image until barium reaches lower ileum (2 hours)
13
Q
Views for SBFT
A
- prone (compress abdomen contents)
- supine (lateral and superior shift of barium & prevents overlap of loops)
- LPO oblique to demonstrate the stomach and 1st part of duodenum
14
Q
Technique for SBFT
A
- L2 centering early images 0 & 15min
- Iliac crest for later images
- 125kVp
- trendelenburg to unfold low hanging superimposed bowel loops of ileum
- imaging is complete when barium reaches ileocecal valve
15
Q
Evaluation Criteria for SBFT
A
- entire intestine on image
- stomach on initial image
- time markers
- no rotation
16
Q
Post Care for SBFT
A
- drink plenty of fluids
- resume normal diet
- warn about white bowel movements
17
Q
when is Enterolclysis used
A
- when oral method fails to provide conclusive information
- small bowel enema using NG, Bilbao-Dotter or Sellink tube passed to the duodenojejunal flexure near ligament of Trietz
18
Q
Enteroclysis Exam
A
- Ba runs at 100mL/min until contrast reaches cecum
- D/C exam
- spot images with and without compression
