duodenal stasis
Introduction
Introduction to duodenal deposition Duodenal stagnation syndrome, duodenal hoarding disease, refers to the duodenal obstruction caused by various causes, resulting in the proximal end of the duodenal obstruction, the clinical syndrome caused by food accumulation. Mainly for upper abdominal pain and fullness symptoms, mostly during or after eating, nausea, vomiting, bile, and sometimes vomiting to relieve symptoms due to upper abdominal fullness. basic knowledge The proportion of illness: 0.006% Susceptible people: no special people Mode of infection: non-infectious Complications: intestinal obstruction
Cause
Cause of duodenal deposition
The superior mesenteric artery oppresses the duodenum (50%):
There are many causes of this disease, the majority of the mesenteric artery compression of the duodenum to form a hoarding (usually accounting for 50% of the total cause), this condition is also known as superior mesenteric artery syndrome.
Other factors (15%):
1 congenital anomaly; 2 tumors; 3 duodenal distal or proximal jejunal invasive disease and inflammation; 5 other congenital malformations: duodenal inversion, gallbladder duodenal colon cord caused by twelve fingers Intestinal obstruction and so on.
Postoperative adhesions (8%):
Adhesion of the duodenum after gallbladder and stomach surgery, adhesion, ulcer, stenosis or sputum syndrome after gastrojejunostomy.
Prevention
Prevention of duodenal deposition
Suffering from stomach, duodenal inflammation, tuberculosis, tumors should try to eat easily digestible food, abdominal surgery to avoid postoperative adhesions.
Complication
Duodenal complication Complications, intestinal obstruction
Easy to have intestinal obstruction, long-term vomiting can lead to water, electrolyte metabolism disorders.
Symptom
Symptoms of duodenal congestion common symptoms bowel nausea constipation upper abdominal pain
1, symptoms
Mainly for upper abdominal pain and fullness symptoms, mostly during or after eating, nausea, vomiting, bile-like substances, and sometimes vomiting to relieve symptoms due to upper abdominal fullness, the disease is periodically recurrent, gradually Aggravation, constipation often occurs.
2, signs
Visible stomach type and peristaltic wave, positive vibration of the upper abdomen, can smell the sound of the water in the abdomen and the bowel sounds.
Examine
Examination of duodenal stagnation
1 barium meal examination can see signs of duodenal stagnation and dilation, or somewhere in the duodenum, the expectorant is suddenly blocked, and sometimes can see reverse creep.
2 gastroscopy can find the cause of obstruction in the duodenal cavity and obstruction of the gastroscope at the obstruction site.
3 When the duodenal juice is taken from the fasting, it is often found that there is food residue.
Diagnosis
Diagnosis and identification of duodenal stagnation
diagnosis:
1. Typical symptoms are an important basis for diagnosis.
2. X-ray barium meal examination features: the horizontal part of the duodenum sees the break of the column (sudden vertical cut); the penile movement caused by the strong forward peristalsis and reverse peristalsis of the proximal intestine; the expectorant passes smoothly in the prone position. The reverse creep disappears.
3. Selective superior mesenteric artery angiography if necessary, showing the anatomical relationship with the duodenum.
Differential diagnosis:
Symptoms of dyspepsia need to be differentiated from peptic ulcers, and sometimes both can coexist. Tumors of the duodenum, such as pancreatic head cancer or giant pancreatic cysts, cause duodenal deposition and can be distinguished by endoscopy or retrograde cholangiopancreatography. Occasionally, the disease can be caused by the abdominal aortic aneurysm pressing the duodenum. The disease also needs to be distinguished from duodenal obstruction caused by stones, fecal stones, mites, and foreign bodies in the duodenum.
