Acute colonic pseudo-obstructive syndrome

Introduction to acute colonic pseudo-obstruction syndrome Acute Colonic Pseudoobstruction Syndrome is a group of syndromes in which the primary or secondary colon is dilated and the colon itself is free of lesions. Often occurs in chronic illnesses and long-term bedridden patients, often in the ileocecal or right colon. The main manifestation is rapid progressive abdominal distension, but slower patients may have no abdominal symptoms, and nausea and vomiting are absent. basic knowledge The proportion of illness: 0.005% - 0.008% Susceptible people: no specific population Mode of infection: non-infectious Complications: amyloidosis malnutrition scleroderma abortion sepsis

The cause of acute colonic pseudo-obstructive syndrome

Its possible pathogenesis: parasympathetic nerves from the spinal cord 2,3,4 (S2 -4) are blocked, leaving the left colon flaccid without tension; the body suffers from stress and other stress, hormonal disorders in body fluids; Poor tension and prolonged bed rest, intestinal peristalsis is weakened, due to the above reasons, intestinal fluid accumulation can not be advanced to the far side, resulting in increasing intestinal pressure, the intestinal lumen is also progressive expansion and secondary colonic pseudo-obstruction.

Acute colonic pseudo-obstructive syndrome prevention

In the clinical application of antibiotics, the types of antibiotics should be carefully selected (broad-spectrum antibiotics are several times higher than narrow-spectrum antibiotics and cause AAC, even PMC) and dosage. Avoid the abuse of antibiotics and PMC.

Complications of acute colonic pseudo-obstructive syndrome Complications amyloidosis malnutrition scleroderma abortion sepsis

Secondary colonic pseudo-obstruction often occurs in the following diseases: scleroderma, amyloidosis, myotonic dystrophy, hypothyroidism, Chagas disease, central nervous system dysfunction, or drug-induced, can also occur in After surgery, pregnancy, induced abortion, revascularization, alcoholism, trauma, cancer and sepsis.

Acute colonic pseudo-obstructive syndrome symptoms Common symptoms Acute abdominal pain, abdominal pain, nausea, vomiting, bloating, nausea

The main manifestation is rapid progressive abdominal distension, but slower patients may have no abdominal symptoms, and nausea and vomiting are absent.

Examination of acute colonic pseudo-obstructive syndrome

Abdominal X-ray film: Both have flatulence and dilatation of the colon, less gas and more fluid, small and scattered liquid level or scattered in one place, no large-span gas-liquid level and overlapping arrangement of ladder-like changes, the number of gas-liquid planes and The size is not proportional to bloating.

Diagnosis and diagnosis of acute colonic pseudo-obstructive syndrome

diagnosis

The best diagnostic method is abdominal plain film. It can be seen that the colon is segmentally dilated, the ileocecal part, the ascending colon is obviously dilated, some patients have gas in the descending colon and rectum, and the nasogastric tube suction can help to identify, the abdominal plain film can not be diagnosed. In the case of the presence of a perforation, a barium enema can be used to establish a diagnosis.

Differential diagnosis

Should be identified with the ileocecal department, sigmoid torsion, acute gastric dilatation and gastric pseudo-obstruction.
