ANATOMY
Parts of S.I:Duodenum: 1st,shortest,widest and most
fixed.Jejunum: 2/5 and feathery appearance.Ileum: 3/5, longest, smooth no feathery
appearance, and joins large intestine at ileocecal valve.

Patient Preparation
1 NPO For 8 hrs.
2 Low residue diet 2 days before the procedure.
3 No smoking or chewing gum during the NPO period.
4 Void before the procedure

1. Ba Meal Follow through
PA 30 minutes
![Page 8: Small Bowel procedures](https://reader033.vdocuments.site/reader033/viewer/2022051020/56815f3f550346895dce143f/html5/thumbnails/8.jpg)
1. Ba Meal Follow through
1 Hour
![Page 9: Small Bowel procedures](https://reader033.vdocuments.site/reader033/viewer/2022051020/56815f3f550346895dce143f/html5/thumbnails/9.jpg)
1. Ba Meal Follow through
2 Hours
![Page 10: Small Bowel procedures](https://reader033.vdocuments.site/reader033/viewer/2022051020/56815f3f550346895dce143f/html5/thumbnails/10.jpg)
1. Ba Meal Follow through
Ileocecal valve

2. Ba Follow through (S.B only)
Plain radiograph(scout).2 cups of Ba ingested (note the time.)15 or 30 min radiograph (center to the iliac
crest “high” to include the stomach, because most of the Ba is in the stomach and proximal S.B.)
Half-hour interval radiographs until Ba reaches large bowel (usually 2 hours)
If more time is needed(< 2hrs) 1-hour interval radiographs are obtained.

2. Ba Follow through (S.B only)
Some routines may include continuous half hr imaging until Ba reaches the cecum. (usually Ba reaches the L.I within 2 or 3 hrs but time varies from one pt to another).
Optional: spot films of ileocecal valve using compression cone.

3. Enteroclysis
Injection of c/m into the S.B. It is a Double contrast method used to evaluate the S.B. the pt is intubated under flouroscopic control with a special
catheter. Stomach → duodenum → duodenojujinal junction.CM
1. Thin BaSO4. ( Coats the mucosa).2. Air or Methylcellulose.
To distend the bowel and provide double contrast

4. Intubation ( S.B enema)
It is a single contrast method where a nasogastric tube is passed through:
pt’s nose→esophagus→stomach→duodenum and into the jejunum.
C.M: thin BaSO4 or water soluble iodinated c.m.diagnostic Therapeutic

4. Intubation ( S.B enema)
Procedure:Single lumen catheter advanced to proximal jejunum(double lumen catheter for therapeutic intubation)C/M injected.(time is noted).Conventional radiographs or optional spot films are taken
at specific time intervals.
