SURGICAL DISEASES, TRAUMATOLOGY, ORTHOPEDICS, UROLOGY : INTESTINAL OBSTRUCTION (ILEUS). Mechanical obstruction (obstructive ileus) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
Etiology. Tumors of the intestines, tumors of other organs, squeezing my intestines, scar congenital and inflammatory narrowing of the lumen of the intestine, blockage of a ball Ascaris, gall stone, foreign body impaction of intestine (but not loops) cicatricial the strand.
The pathogenesis. Compression or obstruction of the lumen of the intestine from the inside or outside without significant disturbance of the intestinal circulation (without compression of the mesentery). Diet ulcer initially suffers a little, intestine makes a strong peristalsis, its resulting plot is filled with content coming from upstream areas, and due to enhanced secretion is stretched, the muscle layer hypertrophies, then comes paresis, stretching, ulceration, perforation, and peritonitis.
Symptoms. Bouts of cramping pains particular location, often accompanied visible to the eye motility. Pain alternate with periods of silence. Asymmetric bloating, loud peristalsis, constipation, alternating with diarrhea. Vomiting, the noise of lapping. Pulse frequent, small, blood pressure falls.
For. Often develops in a gradual incomplete, slowly increasing obstruction.
Much easier when the x-ray study (the presence of multiple horizontal levels bowl). The reduction of the chlorides of the blood.
