Refers to a mechanical intestinal obstruction in patients with clinical manifestations, Caesarean section inspection found only mesocaval expansion blocking lesions. Pseudo-obstruction common causes are:
① intestinal smooth muscle disease;
② myenteric plexus lesion;
③ collagen disease (systemic sclerosis, dermatomyositis);
④ nerve lesions (muscle tension malnutrition, Parkinson's disease);
⑤ endocrine diseases (myxedema, pheochromocytoma);
⑥ Drugs (Clonidine, phenothiazines, tricyclic antidepressants, vincristine). At this point intestinal Electromyography contraction wave lack of visible range or lower, the response of the intestinal expansion disappear or decrease.
