Obstruction of an intestine - a symptom-complex, described disturbance of passage of contents on a gastrointestinal tract. Distinguish a dynamic and mechanical obstruction of an intestine. The dynamic intestinal obstruction can be spastic (extremely seldom) and paralytic.

The paralytic intestinal obstruction is caused by infectious-toxic influences, disturbances of the maintenance of electrolytes in Serum or depression of a blood flow in a wall of an intestine. The infectious-toxic reasons: a peritonitis, a pneumonia, a uremia, an acidosis, a diabetes mellitis, porphyrinic illness and a poisoning with morphia. The reflex factors, able to lead to a paralytic intestinal obstruction: postoperative stress, cholic and renal colics, a pancreatitis, a torsion of ovaries, the big omentum, a trauma of organs of an abdominal cavity and retroperitoneal space, a myocardial infarction.

Signs, current. A constant blunt arching abdominal pain with periodic intensifyings as fights, a nausea, a vomiting congestive contents. Tongue dry, is imposed. A stomach rather soft, distended.

The tumoral intestinal obstruction arises more often at a locating of a tumour in the left half of colonic intestine. Advanced age of the patients, gradually accrueing constipation with the subsequent development of a full intestinal obstruction are characteristic.

The adherent intestinal obstruction meets in 30 % of cases. Solderings can lead to a prelum of an intestine and an obstruction besides massive cicatrixes can squeeze and a mesentery of an intestine together with an intestinal wall. Solderings promote also to development of a torsion. The adherent intestinal obstruction often has relapsing character: usually after a hyperalimentation intensifying a painful syndrome that is caused by a stretching of an intestinal wall and a decompensation of a passage of intestinal contents is marked.
