Radiographic examination of the distal esophagus, stomach and duodenum after administration of CM. Also called Barium meal or GI Series. Used to study
radiographically the form and function of distal esophagus, stomach, and duodenum
UPPER GASTROINTESTINAL SERIES (UGIS)
TYPE OF EXAMINATION UPPER GASTROINTESTINAL SERIES (UGIS) and SMALL INTESTINAL SERIES (SIS)
- Single Contrast Exam
- Double Contrast Exam
- Dual/Biphasic/Welin Technique
- Hypotonic Duodenography
gross pathology, very ill patients, and children. 1 type of contrast media is used usually positive CM.
Single Contrast Exam
small lesion, mucosal lining. Combination of positive and negative CM. Have the patient turn from side to side to cover the whole organ.
Double Contrast Exam
combination of single exam and double exam on the same day.
Dual/Biphasic/Welin Technique
less frequently done examination, duodenal lesion.
Hypotonic Duodenography
suggested introduction of CM through intubation passing through the nose and mouth.
*Liotta
UPPER GASTROINTESTINAL SERIES (UGIS)
PREPARATION:
- Intake of Glucagon prior to examination or
introduction of CM (use to relax abdominal
muscles) - Light Evening Meal
- NPO at midnight
- Food withhold for 8 hrs. (<1 y/o = 4 hrs., 1 y/o = 6
hrs.) - No Breakfast until exam is finished.
UPPER GASTROINTESTINAL SERIES (UGIS)
POST PROCEDURAL CARE:
- Instruct the patient to drink plenty of fluids; and
- To take mild laxative
- long tube structure connecting to the stomach and the colon,
measuring about 22 ft. It is where most of the nutrient
absorption happens.
SMALL INTESTINES
c-shaped part situated proximally and connected
to the stomach, measuring about 10 inches, shortest segment.
(RUQ,LUQ)
Duodenum
has coiled spring, feathery appearance in the radiograph, measuring about 2/5 of the total length of the small intestine (2.5m) where most digestion happens. (LUQ,LLQ)
Jejenum
last section, measuring about 3.5 meters, longest
segment where most absorption happens. (RUQ)
Ileocecal Valve – valve that connects to large intestine
Ileum
Radiographic examination of the three components of the small bowel to detect
abnormal conditions and to study form and function
SMALL INTESTINAL SERIES (SIS)
SMALL INTESTINAL SERIES (SIS)
PREPARATION:
- 2 days low residue diet
- NPO after midnight
- No breakfast
- Cleansing enema be given in some cases to clear
the colon
contrast media is introduced into the duodenum to examine small bowel.
Enteroclysis (double contrast study)
single lumen catheter advance to jejenum, uses water soluble
iodinated contrast media or thin mixture of BaSO4
.Intubation Method (single contrast study)
