Various types of intestinal obstruction due to the following reasons;
(1) mechanical intestinal obstruction
(1) parenteral factors: ① adhesion and adhesion with oppression. Adhesions can cause intestinal folding, reverse, resulting in obstruction. Congenital adhesions seen more children because of abdominal surgery and intraperitoneal adhesions, the inflammation was particularly prevalent in adults. ② incarcerated hernia, or hernia. ③ parenteral tumor or abdominal mass oppression. ④ volvulus. As often caused by adhesions.
(2) the reasons for the intestine itself: ① stenosis and congenital deformities obturator. ② inflammation, tumor, anastomosis and other factors caused by stenosis. For example, inflammatory bowel disease, intestinal tuberculosis, radiation injury, intestinal tumors, such as intestinal anastomosis. ③ intussusception. See fewer adults, often caused polyps or other lesions.
(3) lumen within reason: As a group of Ascaris lumbricoides, cholelithiasis, and foreign body Fenkuai caused not common.
(B) Power Ileus
(1) of paralytic: major abdominal surgery, peritonitis, abdominal trauma, retroperitoneal bleeding, anesthetics, pneumonia, empyema, hypokalemia, and other systemic metabolic disorder can cause paralytic ileus.
(2) spastic: intestinal inflammation and nervous system dysfunction may lead to temporary intestinal cramps.
(3) obstruction of blood supply
Mesenteric artery thrombosis and embolism or mesenteric venous thrombosis is the main reason.
Intestinal pseudo-obstruction, it is a bowel obstruction signs and symptoms, but no evidence of mechanical obstruction syndrome, it could be acute and chronic, growing attention in recent years, is generally considered to be intestinal neuromuscular degeneration results. Connective tissue diseases, primary myopathy, certain endocrine diseases, diseases of the nervous system and some drugs can cause secondary intestinal pseudo-obstruction, intestinal pseudo-obstruction of the primary reasons is not very clear.
