Contraindications

to postoperative review of the upper gastrointestinal tract 1.
Complete GI obstruction2
.
Acute phase of
gastrointestinal bleeding3.
Perforation
of the digestive tract4.
Patients with poor physical condition and difficulty tolerating the operation method
of the examination are divided into single contrast contrast and air barium dual angiography
.

One.
Contrast medium 100% (W/V 200G barium sulfate type II dry suspension with 200ml of water)

Two.
Preparation
before contrast 1.
It is necessary to stop drugs that affect the contrast or gastrointestinal function, such as bismuth hypocarbonate and calcium
gluconate.

2.
Vegetarian dinner the day before barium meal inspection, and fasting after dinner (including no milk, strong tea).


3.
Fasting and abstaining from water (including not taking medication)
after waking up in the morning on the day of the examination.

4.
Critically ill and mobility patients need to be accompanied
for examination.

Three.
Operation step
1.
The patient takes the upright position, first do chest and abdomen fluoroscopy, observe whether there are lesions in the lungs and mediastinum, the shape, position and mobility of the transverse septum, the shape of the gastric vesicles, whether there is a soft tissue mass shadow in the cardia and fundus, and if the stomach is displayed, it indicates that there is fasting retained fluid
.
Pay attention to whether the small intestine has gas, dilation and gas level, and patients with intestinal obstruction can not do barium examination, pay attention to whether there are gallstones, kidney stones and other abnormal calcifications
.

2.
After chest and abdomen fluoroscopy, instruct the patient to take a packet of foaming agent, flush with 5 ml of water, swallow as soon as possible without belching, and then, upright oral barium to observe the first mouthful of barium, observe the pharyngeal structure and swallowing movement, and take positive lateral position if
necessary.

3.
Observe whether the barium passes through the esophagus smoothly, whether there is a stenosis obstruction, niche, whether the softness of the mucous membrane is normal, and whether the barium passes through the cardia is observed in the right anterior oblique position, the positive position, and the left anterior oblique position, and if necessary, dot the piece
.

4.
Lay the examination table flat and instruct the patient to turn it twice to the right, in order to evenly coat the barium agent on the surface of the gastric mucosa, forming a double contrast
of barium.
Multi-angle observation of the expansion of the morphological position of the stomach and duodenum, mucous membrane and peristalsis, etc.
, and taking spot films

5.
Photo program
(1) Lie on the right anterior oblique position on your back and observe the double contrast
of antrum and duodenal barium.

(2) Lie on the left anterior oblique position and observe the double contrast
of barium in the fundus and stomach body.

(3) Prone (flipped to the right) right posterior oblique position (equivalent to left anterior oblique position), observe the filling phase
of the gloenteroduodenal ball and descending part of the gastric antrum.

(4) Flip to the right to the right anterior oblique position of supine or supine to observe the horizontal part of the glopeloduodenal bulb and descending part and the proximal jejunum
.

(5) Upright anterior oblique or positive position, observe the gastric fundus and cardia double contrast phase
.

Four.
Other:

(1) Diagnostic requirements: cavity wall line continuous, no bubbles, no flocculation, mucosal folds display well, satisfactory
contrast.
The lesion is clearly displayed and the diagnosis is clear
.

(2) Body position requirements: the correct photographic position and position, including the display
of the upper and lower left and right edges, parts and areas of interest.

(3) Imaging requirements: Imaging ranges from the esophagus to the Qud's
ligaments.
The test person's data must include the year, month, and day, examination number, hospital name, and patient's name, which does not affect the display
of the diagnostic area.

(4) The photographic requirements are as follows: esophageal double phase, esophageal filling phase, supine left anterior oblique gastric double phase, supine right anterior oblique gastric double phase, supine gastric body, antral filling phase, gastric fundus, cardia left anterior oblique double phase, gastric fundus, cardia left anterior oblique double phase, duodenal ball and circle filling phase, duodenal ball double phase, duodenal ball compression phase, upright or semi-recumbent total gastric filling phase
.
If a lesion is found, the lesion site must include more than two phases to facilitate a clear diagnosis
.
