Small Bowel procedures
Reem A. Al-Thekair
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.
For 8 hrs.
2 days before the procedure.
PA 30 minutes
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.
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.
To distend the bowel and provide double contrast
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.
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.
